What happens if you take NFS out of the equation? Try creating a local user on the K12LTSP server and give her a non-NFS home directory. How do the slow apps respond then? Then create a Samba/LDAP user but give her a local home directory (e.g., "/tmp/username") and see how the apps respond. I'm guessing that you've got NFS locking issues. Every time I've seen behavior like this that seemed to be the culprit, but an update has always fixed the problem before I got time to track it down further and figure out *why* locking was a problem. --matt -- Open Source Software Engineering Consultant http://majen.net/ From mel at melwade.com Mon Jan 1 17:07:20 2007 From: mel at melwade.com (Mel Wade) Date: Mon, 1 Jan 2007 09:07:20 -0800 Subject: [K12OSN] k12ltsp.org down?

But typically releases happen in March/Sept and the following seasonal holiday (summer or christmas) k12 is released. Ofcourse nothing prevents k12 to set up its own repos. -- Wishing you very best for the New Year 2007 Regards, Sudev Barar From dyoung at mesd.k12.or.us Tue Jan 2 03:40:22 2007 From: dyoung at mesd.k12.or.us (Dan Young) Date: Mon, 01 Jan 2007 19:40:22 -0800 Subject: [K12OSN] A couple more oddities with K12LTSP 6.0 In-Reply-To: <458B25E7.8070502@hvja.org> References: <458B25E7.8070502@hvja.org> Message-ID: <4599D426.1080107@mesd.k12.or.us> Huck wrote: > on bootup I get this message: > > system message bus: unknown group netdev in message bus configuration > file... This was mentioned on the fedora-devel list as a known issue. It's a harmless message regarding a Debian-specific configuration that went into the Avahi package.

I posted this a couple of weeks ago and never did hear anything back. I figure everyone was probably quite busy with the holidays and I may have been looked over. I figured I would try once again. I've been working on this and haven't came up with any luck so far. I have two workstations that were working on my K12LTSP 4 box which I cannot get to come up on the K12LTSP 5. I have three machines of the same hardware configuration. One works, the other two do not. I have tried to copy the lts.conf information from the one that works: [C112] PRINTER_0_DEVICE = /dev/lp0 PRINTER_0_TYPE = P X_MODE_0 = 800x600 40 800 840 968 1056 600 601 605 628 +hsync +vsync to the two that are not currently working: [C113] [C116] *Note - I did not put this on the same line, I'm must showing that both have the same config. PRINTER_0_DEVICE = /dev/lp0 PRINTER_0_TYPE = P X_MODE_0 = 800x600 40 800 840 968 1056 600 601 605 628 +hsync +vsync In the global section, the XSERVER = "auto" I tried adding XSERVER = "mga" to the individual lines as well to see if that would help, it did not. The video cards in all three are AGP Matrox Millenium II (MGA2164WA-B) The error I am getting basically goes as follows: Scanning for video card.. then it says to check /tmp/mnt/xorg.log for errors (which is not in /tmp/mnt/xorg) Then I receive xserver failed. As mentioned earlier, I did have these working under K12LTSP 4. I did have an issue earlier when I didn't realize that the dhcpd.conf file was changed. So if something in lts.conf has changed, that may be something I don't know. I do have several other terminals (4 working), one of which is an identical machine as two that are not working. I did think about trying to redo the image for the network boot, but I don't really know why that would change anything.

K12LTSP 6.0.0 Release Notes =========================== K12LTSP 6.0.0 is based on Fedora Core 6, with a large number of changes including: * LTSP 4.2 update 4 * A bunch of packages from Fedora Extras * Hundreds of updated FC6 packages * A handful of K12LTSP packages, just to spice things up This release of K12LTSP is slightly different than past releases in that there is no specific "LTSP" install option. If you want do a "normal" Fedora Core 6 install from K12LTSP 6, simply uncheck the "LTSP" package group. The "Education" package group has been split up into two groups. Now there is "Eduction (K- 5)" which includes tuxtype, tuxpaint, gcompris, etc for the younger kids, and there is "Education (6- 12)" which includes gperiodic, qcad, etc for the older kids. Also note that if you install the LTSP package group, the DHCP and DNS use alternate configuration files: DHCP: /etc/dhcpd- k12ltsp.conf DNS: /etc/named- k12ltsp.conf Changelog ========= K12LTSP specific packages: root- desktop- urls 0.6- k12ltsp.6.0.0 - include a "Remove Icons" icon to complement the "Push Icons" icon - "Get Acrobat Reader" now fetches Acrobat Reader 7.0.8 k12ltsp- education

I made all hits to http://www.k12ltsp.org/phpwiki/* go to a redirector page. The content in phpwiki is now at http://www.k12ltsp.org/phpwiki-old/ & I excluded that url in robots.txt so that it won't get indexed. In a couple of weeks, we'll remove the old phpwiki all together. NOTE: this is not a rant about phpwiki, it is the DB4 database that is driving me crazy... we switched to mysql for the new wiki. -Eric From ascensiontech at gmail.com Tue Jan 2 17:30:22 2007 From: ascensiontech at gmail.com (Peter Hartmann) Date: Tue, 2 Jan 2007 12:30:22 -0500 Subject: [K12OSN] K12LTSP 6.0.0 Released In-Reply-To: <459A34DB.0DA4.007D.0@shenandoah.k12.ia.us> References: <458EC82E.6090305@mail.mesd.k12.or.us> <459A34DB.0DA4.007D.0@shenandoah.k12.ia.us> Message-ID: <9bd317560701020930h698bb045x3ace54d32c3cfe7a@mail.gmail.com> I did an upgrade from fc5 to fc6 on my laptop and it went smoothly. but I don't have the ltsp specific bits installed just the eduapps.

I haven't tested that out but I'll take a look at it tomorrow. I definitely think it's some NFS, DNS, network or permissions issue. What kind of update did you do to fix the problem? You mean just a 'yum update'? ~ Julian From julian_yap at yahoo.com Tue Jan 2 18:11:34 2007 From: julian_yap at yahoo.com (Julian Yap) Date: Tue, 2 Jan 2007 10:11:34 -0800 (PST) Subject: [K12OSN] Fedora Legacy support no longer In-Reply-To: <774593a20701011854i25e08da8n7074598533609b97@mail.gmail.com> Message-ID: <688010.14834.qm@web35607.mail.mud.yahoo.com> If you want longer support, can't you just pick the K12LTSP installs based off of RHEL sources? For example, K12LTSP 4.2.x.EL should be updated until Feb 29, 2012 (http://www.centos.org/modules/smartfaq/faq.php?faqid=42). RHEL5 is due to come out late February 2007.

Updates are available for 7 years, I think. It's also similar to Fedora, which might be a plus since Fedora is what you've been using. -Rob --- john wrote: > Hi All, > > > I am in the process of moving a web-server off of > Fedora 4 and onto a flavor > that will be supported for a while.

Unfortunately, I don't have the answer either. It gets especially muddy, when your server is an LTSP server, serving desktops to thin clients. I think what you'll find is that server-type things, like the kernels, apache, samba, postgres and others will have security updates for 5 years. But, desktop things, like Gnome Firefox will only have updates for 3. Jim. Rob Owens wrote: > Jim, is there a list of packages which qualify as > "server"?

Late february RHEL 5 will be released which will be supported until something like 2014, and I guess CentOS 5 will be released shortly after. If you're used to using yum and the 'Red Hat way' of Linux I think CentOS is a better choice than Ubuntu or another Debian-based distro. But of course you can always try both and see what you like best. Nils Breunese. -------------- next part -------------- A non-text attachment was scrubbed...

See if the " non-working" client now works.There's so many varibles even from "thought to be identical" clients. Maybe a bios setting such as PCI, auto or manual,etc. Maybe all worked hunky/dory with FC4 but FC5 doesnt like the bios settings of the two non working clients.Possibly irq conflict or such( at bios level, not linux level). If the client does work,,then you know it is the video card. possibly a different firmware version on the non> OK>working clients. This is a bit of a hassle i know,but at least you have eliminated one eliment from the equation. If the swap makes no diff check closer at bios setting pertaining to PCI-Auto versus- manual,,and see what your working client is set to.. Also are you sure the two non-working clients are receiving the actual ip addresss that it should have( that you assigned them in dhcp/lts.conf files). as it boots up? You have to look quick at the first few lines of the boot process!!! This is a possibility,in that you have a wrong number/letter in your dhcp entrys for the two non-working clients hence they are just using the default "auto" XSERVER setting that is entered in the lts.conf.. This sint too scientific,,but may be worth a shot.

The job of our schools is nothing less than to help co-create the 21st-century citizen. We want our kids to be active, engaged citizens of the world. They'll be workers if they are that, too... that part will take care of itself. We want them to be able to engage in the world around them and to make it better. Nothing less than that is our task as educators." Chris Lehman is the principal of the Science Leadership Academy (SLA) in Philadelphia, Pennsylvania, and a proponent of "School 2.0." Here is his description of SLA: "The Science Leadership Academy is a new high school that opened in September 2006 in partnership with The Franklin Institute and the School District of Philadelphia. Opening with a powerful School 2.0 vision and a 1:1 laptop ratio, SLA looks to redefine the learning spaces and tools our students, parents and teachers use. The school uses open source tools such as Moodle, Elgg, Gallery and homegrown school information system software to create a robust school-web portal to support the learning that happens in classrooms. Our goal is to create 24/7/365 learning environment for all members of the community." (From his accepted proposal to speak at NECC this year.) (We'll be holding open workshops on Moodle, Drupal, and Web 2.0 (with Will Richardson) at SLA in Philadelphia the week of January 29 - February 3. For more information, please visit the www.EdTechLive.com workshop page. To join in the discussion on School 2.0, please visit www.School20.net.) Notes: * Chris spent 9 years at the Beacon School in New York as a teacher, coach, technology coordinator, and administrator. The experience was amazing. Has come home to Philadelphia to start SLA--"a small progressive public high school with a focus on technology infusion across the curriculum." * While SLA is a public school, their first class of 110 students (the 9th grade) have had to apply for admission and each applicant had a personal interview. Future classes will have current students on their admissions committees. * Microsoft's School of the Future also opened in Philadelphia this year ("they have a nicer gym than we do"). If SLA is reinventing the wheel, School of the Future is "blowing up the car." Both have a focus on project-based learning and re-imagining what a school can look like, but SLA is based on more familiar pedagogies (sounds like it would be really interesting to interview someone from School of the Future!). * They are using Linux, Moodle, and Elgg and consider themselves an "open source" school. * "At the end of the day, it isn't about what computer you use, it's about the pedagogy and how the teachers implement it, and what your goals are for how your teachers and students use it." Technology doesn't change the classroom, pedagogy changes the classroom. The new tools make it affordable to integrate the technology and support the pedagogy, but the pedagogy comes first. If you put the technology first, the tail will wag the dog. "SLA was never a laptop school first, it was an inquiry-drive, project-based school with five very strong core values, and the technology we use supports those core values." * The five values are: inquiry, research, collaboration, presentation and reflection. * Blogging has helped him be a better teacher and administrator through "reflective practice." It has also helped them through the starting of SLA by allowing for "transparent" dialog by blogging during the planning process--which also produced a very involved community. He feels that this made the SLA very "School 2.o" by doing this from the start. * "We've got to teach kids to be powerful, careful, and critical consumers and producers of information and content." "The fundamental jobs of our schools as we move forward in this new era is to teach wisdom... unless we realize that our job is to teach kids what to make sense of this world, how to critically analyze what they see out there, and how to do something with it, then it doesn't matter what we do with the technology." * "We can't be complacent in education--the stakes are too high... the fear of what could go wrong can't stop me from doing what is right." * All of the students went nuts when they first got instant messaging on their laptops--and the parents were really worried about their children having access to instant messaging during school. Chris's response was: the kids are going to figure out how to have access to these tools even if we try to block them, and they will need them in college and in the workplace eventually... so let's help them to figure out how to use them responsibly now. * They did have a problem with misusing instant messaging (including bullying)... and the students started solving the problems themselves, as they wanted there to be consequences so that they could keep their laptops. * Chris's definition of School 2.0: School 2.0 starts with a progressive pedagogy that recognizes that the role of schools has changed, and that the role now is to help students navigate an ever-changing world, and to help them have the skills they need to adapt, to create, to judge, to synthesize, and to analyze. It has to be about teaching kids to become critical consumers and producers of the information around them... We can't assume that we have all the answers--we've got to teach the kids to take a core set of skills and find rich, powerful answers that are out there in the world for themselves... School 2.0 doesn't have walls to it--it recognizes that this happens all day every day. When we invite the world in rather than shut it out, we create communities and institutions that are real and authentic and caring, and that kids recognize as valuable in their own lives. * School 2.0 isn't about letting students do anything they want. It's about rigor and passion--keeping students engaged, but also helping them understand the need to work even when we don't want to. * "We actually do know how to fix what's wrong in education. Because the fact of the matter is that there are lots of places in this country where schools are doing just fine... they are good, healthy places where kids are doing well. We know, sadly, that most of those places are not in cities, and when we talk about the crisis in education, what we are really talking about... is urban education... It's not just schools size, it's teaching load... We want to change education?... Let's have teachers teaching fewer classes and planning more... Do that and we will change education." -- Steve Hargadon steve at hargadon.com 916-899-1400 direct www.SteveHargadon.com - (Blog on Educational Technology) www.K12Computers.com - (Refurbished Dell Optiplexes for Schools) www.EdTechLive.com (Podcasts, Workshops, & Conferences) www.TechnologyRescue.com - (Linux Thin Client Solutions) www.LiveKiosk.com - (Web Access and Content Delivery Solutions) www.PublicWebStations.com - (Disaster & Shelter WebStation Software) www.K12OpenSource.com (Public Wiki) www.SupportBlogging.com (Public Wiki) From microman at cmosnetworks.com Wed Jan 3 06:46:57 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Wed, 03 Jan 2007 01:46:57 -0500 Subject: [K12OSN] RFP to replace SASIxp in my school district Message-ID: <459B5161.8070805@cmosnetworks.com> Hello folks, It has been a while, and I hope that folks have enjoyed their holidays and have welcomed the new year in well.

There was only ONE fedora legacy update to FC4 - which hardly qualifies as good support. The good news I have heard in the discussions about the demise of the fedora legacy project is 1) potentially extending the life of the Fedora core support, and 2) building "extras" repositories for the up-coming RHEL5/CentOS5. If both of these are done, it will largely fill in the gap that fedora legacy intended to bridge. -Eric From dtrask at vcsvikings.org Wed Jan 3 15:13:12 2007 From: dtrask at vcsvikings.org (David Trask) Date: Wed, 03 Jan 2007 10:13:12 -0500 Subject: [K12OSN] needed: recommendations for Linux flavor with ongoing=?ISO-8859-1?Q? support?= In-Reply-To: References: <151198.24756.qm@web32801.mail.mud.yahoo.com> Message-ID: "Support list for open source software in schools." writes: >SUSE!

I have always thought that what people needed was a distro that split the base OS and core libraries away from the applications so once you had a working kernel and device drivers you wouldn't have to change (and likely break) them just to get a version-level update to openoffice or firefox. When you replace your hardware you would want to install a new kernel with current device drivers for it. So far none of them take that approach, though. -- Les Mikesell les at futuresource.com From spowers at inlandlakes.org Wed Jan 3 16:10:08 2007 From: spowers at inlandlakes.org (Shawn Powers) Date: Wed, 3 Jan 2007 11:10:08 -0500 Subject: [K12OSN] NFS help Message-ID: I've been using NFS for years, and it's been great.

Could someone point me in the right direction to diagnose, and hopefully fix NFS? The symptoms are: 1) Programs on thin clients for users with NFS home directories don't open, they just sorta hang and hang. Sometimes they'll start after 10 minutes. 2) double clicking a file in nautilus will sometimes open the file (in openoffice), but then nautilus will hang. 3) on my OSX clients, Microsoft Word complains that either a file is locked, or it can't lock a file -- both errors are common. If I try to: service nfs restart the part that says, "Shutting down NFS daemon: FAILED" always comes up, but then further down it says, "Starting NFS daemon: SUCCESS" I can't find any useful errors, but rebooting the NFS server does fix the problem for a while. It first, of course, locks up every client unless they've logged out, so it's not a great solution, and was not a great way to start the year. :) Thanks for any insight, -Shawn -- Shawn Powers Technology Director Inland Lakes Schools PHN: 231-238-6868 x9174 FAX: 509-356-7024 spowers at inlandlakes.org Work Website: http://techcorner.inlandlakes.org Personal Blog: http://www.brainofshawn.com ---- The views, opinions, visions, thoughts, comments, sarcastic whims, forecasts, poetic outbursts, cynical wit, future plans, implementation ideas, OS preference, curricular insight, ice cream preference, or anything else I might infer are not the views of Inland Lakes Schools.

Not everyone thinks this, of course. But enough people seem to--witness the Samba project, and Jeremy Allison's resignation from Novell--and GPL3 is being modified to prevent deals like the one between Novell & MS, such that Novell may have a hard time shipping future versions of Samba. No doubt there will be other projects that adopt GPL3, making Novell's future murky. Choosing SUSE at this point may not be 'highly dangerous' but perhaps 'dubious'.

I can look at packaging up the ED version, but I generally try to avoid doing that as much as possible - it always ends up causing me a great deal of grief ;-) The first thing I would recommend is submitting a request for enhancement in the Fedora Extras bugzilla: https://bugzilla.redhat.com/bugzilla/ -Eric From petre at maltzen.net Wed Jan 3 18:12:37 2007 From: petre at maltzen.net (Petre Scheie) Date: Wed, 03 Jan 2007 12:12:37 -0600 Subject: [K12OSN] needed: recommendations for Linux flavor with ongoing support In-Reply-To: <1167844454.7355.22.camel@oldmoola.futuresource.com> References: <151198.24756.qm@web32801.mail.mud.yahoo.com> <459BD7FD.9050003@cmosnetworks.com> <20070103114306.2d274fd3@laptop.thesizemores.us> <459BE194.7030609@maltzen.net> <1167844454.7355.22.camel@oldmoola.futuresource.com> Message-ID: <459BF215.8020502@maltzen.net> Les Mikesell wrote: > On Wed, 2007-01-03 at 11:02 -0600, Petre Scheie wrote: > >> --and GPL3 is being modified to prevent deals >> like the one between Novell & MS, > > Errr...

I expect other projects will do likewise, though certainly not all. Linus has said he thinks GPL3 is a bad idea, so the kernel may not be moving; OTOH, I *think* I recall reading somewhere that he also said that if the consensus in the kernel community evolves to favor GPL3, then he would go along with it (but I could be wrong about that). So, in a year, say, Novell will be stuck with the last version of GPL2 Samba. Either they don't get a new version or they fork it themselves, and it's not clear they have the resources to handle that. How many other projects that Novell uses in SUSE will move to GPL3? That's what makes Novell's future murky, making SUSE a dubious choice for now.

I have run or tried most flavors at one time or another. used RH pretty solidly until FC and have not been very happy with FC. the --Buntu distros and I do not seem to like each other and I have lots of trouble just getting it to work.

The FSF has made it very clear that virtually all of that software will be GPL3'd. Oops, kinda hard to make a functional distro w/o glibc...or grep...or awk...or sed...unless you want to port FreeBSD's libc, etc. Maybe that's what Novell will have to do. The SuSE distro does have an component of actual danger to it as well. When that five-year "no suing" agreement ends, either Microsoft demands greater extortion^H^H^H^H^H^H^H^H^H fees, or Microsoft starts going after SuSE customers. Novell has a nice, handy-dandy list of all of its customers, and due to the agreement with MS, it might be easier to subpoena that list...if MS doesn't already have it. No, I wouldn't risk my business--or my district--by going with SuSE anymore. --TP From dhuckaby at paasda.org Wed Jan 3 19:08:58 2007 From: dhuckaby at paasda.org (Huck) Date: Wed, 03 Jan 2007 11:08:58 -0800 Subject: [K12OSN] compiled documentation for K12LTSP apps In-Reply-To: <459BFE70.9090108@maltzen.net> References: <459BF6AD.9040205@paasda.org> <459BFE70.9090108@maltzen.net> Message-ID: <459BFF4A.9070602@paasda.org> point me in the direction and I'll do my best...=) (I honestly dunno wiki address ;) --Huck Petre Scheie wrote: > A page on the wiki with all this info would be great (nudge, nudge, > wink, wink). > > Petre > > Huck wrote: >> I compiled this list this morning for the latest site where I've >> installed K12LTSP(an elementary school).

The directory and its contents are owned by user A, and I want user B to have rwx permissions on that directory as well. So I tried adding user B to /etc/groups using vigr and doing the following. The directory is 775 but user B still can't do touch in the directory. When I use the 'groups' command as that user, I don't see that 'B' is part of the group 'A'. Here's what the relevant part of my /etc/groups file looks like. A:x:508,B Thanks for any advice you can give me! John -------------- next part -------------- An HTML attachment was scrubbed...

It also says that because of a hardware bug, it can't probe the card to find out how much RAM it has, and so it guesses at 4MB. Probably because of that same hardware bug, in trying to use the MGA driver, it is unable to allocate memory for the frame buffer, and then X dies. I suggest trying a couple of things: 1. In the lts.conf file, specify the vesa driver for this workstation, thusly: XSERVER = vesa The vesa driver is sometimes labeled as being slower, but I find it's often unnoticable, and slow is better than non-working. You may need to also set X_VIDEORAM = 4096 or some such to get it to work. 2. Switch the video card with one from one of the working machines. If the problem follows the video card, it may be that the cards in those machines are not all identical. In which case, you may have to replace the non-working card. Used video cards can be found for $5-$10 that will work fine. Petre Michael Elliott wrote: > Petre - > > Thank you for that suggestion. I was able to get the command prompt and > try to startx.

The point is, of all the distros out there only SuSE has implicitly admitted that it is violating M$ IP by accepting a covenant for it's customers that states M$ will not sue them for any IP violations. Which by the way are not listed. It's very clever in that the agreement does not list the infringing IP. In addition it deliberately circumnavigates GPLv2. This is why many, including myself, feel that it is violating the intent of the GPLv2. I am very disappointed in SuSE for handing M$ the FUD they wanted. I can still hear Ballmer "Only SuSE has patent peace!" Samba does not violate any M$ IP. M$ wishes it did. We can thank the brilliance of Andrew Tridgell for that. Mono is another matter. In addition, Novell pays M$ royalty for each version of SuSE it sells. It is sacrilege that M$ should get money from indirectly selling Linux. Anyway, bottom line, I don't consider SuSE a true Linux distro anymore. They sold out cause they needed the money. For M$ it's a win-win situation. They get the FUD they wanted plus get the FLOSS community to abandon one of the top 3 distros. And for anyone that buys the BS that this deal was about creating better interoperability, all I have to say is M$ has been hard at work doing it's best to thwart Linux-Windows compatibility for a long time. They hate Samba and tried to obfuscate it out of existence. But Tridgell is not someone easily obfuscated :) > > -- > Les Mikesell > les at futuresource.com > > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see > -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From timothy.hart at gmail.com Thu Jan 4 03:15:53 2007 From: timothy.hart at gmail.com (Timothy Hart) Date: Wed, 3 Jan 2007 22:15:53 -0500 Subject: [K12OSN] compiled documentation for K12LTSP apps In-Reply-To: <459C078C.7050106@maltzen.net> References: <459BF6AD.9040205@paasda.org> <459BFE70.9090108@maltzen.net> <459BFF4A.9070602@paasda.org> <459C078C.7050106@maltzen.net> Message-ID: <464c38cc0701031915m49074f46j3b25b1f086c263ae@mail.gmail.com> I added that to the documentation page.

This justification of the deal just makes me laugh!! (NOTE: this message is not directed at anyone on the list, just feeling the need to add my own $0.02 to the argument.) If MS _REALLY_ wants to help with the "Linux/Windows compatibility", all they would have to do is start following the _STANDARDS_ already in place. Not try to create there own, or tack on their crazy crap on top of the standards they are already "following" (XML comes to mind for Word). As a company, they make a concise decision between (1) Following standards already in place or (2) by creating new formats of their own. By going with (1) they _INSTANTLY_ create interoperability between them and everyone else, no extra work needed. And they get to save man-hours, and money by building on top of something already in place. By going with (2) they limit (if not completely eliminate) interoperability between them and others. The have to put extra man-hours and money into building their format from the ground up. Don't get me wrong, there are both _VERY_ valid ways of doing business. Anyone, in any line of work, needs to make these kind of decisions all the time. Both have there own set of positives and negatives. (leave it up to the ready to make a list :-) ) _BUT_ it is a decision that is made by the company/individual. No agreements between different parties need to be made. IT IS COMPLETELY INTERNAL. If MS _REALLY_ wanted to make things more compatible, then all they would have had to do is go with decision #1. NO BUSINESS DEAL NEEDED. This is why I can't not help but think that there is some kind of ulterior motive here at play. P.S. - I know there is also a combo of the two, were you build something from the ground up, but you work "openly" so others can see, and eventually build on what you started. But I my mind that more or less falls into the #1 area.

It's something similar to what's described here: http://www.faqs.org/faqs/sgi/faq/apps/section-26.html I had IPTables firewall running on the NFS/SMBLDAP server. I needed to statically assign the NFS Lock Manager port (since it's randomly assigned) and open up that port. An excellent guide here: http://www.stevesearle.com/tech/faq.html#nfs0010 Also: http://www.lowth.com/LinWiz/nfs_help.html There were some other NFS related ports I needed to fix too (and set to static) according to the above link. ~ Julian --- Matt Oquist wrote: > I'm guessing that you've got NFS locking issues.

What you're doing here is called a "flood" ping, and you're specifying a packet size of 15,000 bytes/packet. I will do this until I fill up the link. I've actually pegged an OC-12c with multiple such ping sessions. I would have, say, four of these from Box A pinging Box B, and I'd have another four or so from Box B going to Box A. So, you should have no trouble filling up a 100Mbps client link. Here's another way: fire up full-screen TuxType or TuxMath sessions on all of your clients, simultaneously. This *WILL* generate a boatload of traffic. All you need are 15 simultaneous sessions of this to peg the server's Gig-E link (one of them will use 73Mb/sec). Then, as Dan mentions above, check out the port statistics on your switch, assuming that it's a managed switch (e. g. BayStack 450T, Cisco Catalyst, or Amer.com SR48G2i). If you're not using a managed switch, it actually would be a wise investment; 24-port BayStack 450T's with a fiber Gig-E interface can be had on eBay for about $200.

There will be no more releases of Fedora Core or Fedora Extras. Wait! Where are you going? Come back! I'm serious. We've talked all along about how there should be no differences in how packages are treated whether they are in Core, or they are in Extras; no differences depending on who maintains the package. The best solution to this? Eliminate the distinction between Core and Extras entirely. Starting with Fedora 7, there is no more Core, and no more Extras; there is only Fedora. One single repository, built in the community on open source tools, assembled into whatever spins the Fedora community desires. Are we there yet right now? No. There's a lot of work to be done, and we're looking for help. What's left of the Core Steering Committee is going to work with the Fedora Board and FESCO to figure out just how this new combined repository is going to be governed and managed. In the meantime, just because we're not going to have a release of Core or Extras doesn't mean we're not going to have a release. Hence, Fedora 7. Name TBD, but probably not 'Bride of Zod'. http://fedoraproject.org/wiki/Releases/7 The current schedule is: 23 January 2007 | F7 Test1 development freeze 30 January 2007 | F7 Test1 Release 20 February 2007 | F7 FEATURE Freeze | F7 string freeze | F7 Test2 development freeze 27 February 2007 | F7 Test2 release 19 March 2007 | F7 translation freeze | F7 Test3 development freeze 26 March 2007 | F7 Test3 release ... Continual freeze. Only critical bugs fixed ... 5 April 2007 | Final devel freeze. 26 April 2007 | F7 General Availability And, what would a release be without features. We've identified 28 features that we'd like to include in the release, available at http://fedoraproject.org/wiki/Releases/7/Features: - Modify the build system to support this new paradigm - Merge Core and Extras in source control - Use the new pungi tool to spin all releases - A Fedora Desktop spin - A Fedora Server spin - A Fedora KDE spin - Make LiveCDs as a part of the distribution release process - Ability to customize non-packaging distrubution parameters - Switch to libata drivers for PATA support - Speedup of bootup and shutdown - Make wireless rock-solid - Add wireless firmware for all the chipsets we can - CodecBuddy - Fixing the proliferation of dictionary packages - Support encrypted filesystems - Fast user switching in the desktop - Fix the firewire stack - Switch to a tickless kernel by default - Fix unnecessary wakeups across the distribution - Add KVM virtualization support to our tools - Investigate (but probably don't switch to) new init technologies - Add the nouveau drivers for nVidia cards - Speed up Yum and RPM - Add support for RandR 1.2 - Switch to syslog-ng - Make the update system useable by all More information on each of these features is available on the wiki, including responsible people and plans. If you'd like to chip in on these features, please, do! If you've got new features you'd like to add, and you are willing to do the work, or have the ability to get others to do the work for you, we can add them too. Note that Test2 is the feature freeze. Here's to making Fedora 7 the best release yet!

That's not at all clear - and Novell has explicitly stated the opposite.

I think you missed the other half of the arrangement. Novell still claims rights to the original UNIX code (in spite of SCO's claims) and MS now includes Services-For-Unix and other things that might possibly infringe. It's better for everyone for MS to be able to use good, well tested designs instead of inventing something worse and putting it on our networks. > They hate Samba > and tried to obfuscate it out of existence. But Tridgell is not > someone easily obfuscated :) Samba is really only interesting to someone running Windows anyway. If the GPL didn't prevent people from distributing all the components you need together, we might have had some real competition to windows by now and made it irrelevant. -- Les Mikesell les at futuresource.com From dyioulos at firstbhph.com Thu Jan 4 20:46:22 2007 From: dyioulos at firstbhph.com (Dimitri Yioulos) Date: Thu, 4 Jan 2007 15:46:22 -0500 Subject: [K12OSN] very unexpected In-Reply-To: <459D63CC.9030702@paasda.org> References: <459D63CC.9030702@paasda.org> Message-ID: <200701041546.22765.dyioulos@firstbhph.com> On Thursday 04 January 2007 3:30 pm, Huck wrote: > just received this from the principal of the school I set up the latest > K12LTSP lab. http://www.hvja.org/ (warning website 1 page only ;) > > [quote] > Hi Holley, > > Wow.

Otherwise, I've got an 'expect' script that takes a ID and PW as parameters and PW to the given ID. Then you just write a script that parses the file for each ID & PW and calls the expect script accordingly. I can post the expect script if you're interested. Webmin might be easier, but writing scripts like this is more fun. ;-) Petre Ray Garza wrote: > Hello Script Gurus, > > Anyone know how to create user accounts from a text file using scripts? > > Example: > > user_accounts.txt > "username1","password" > "username2","password" > "username3","password" > "username4","password" > > convert that list into users on a local machine > > Better yet I need to convert a dbase file of usernames and passwords into > valid local user accounts.

On the older versions (pre 5.0) of K12LTSP I was able to simply install the OS and boot the client with a boot disk.

I can see your point of view Les. Shuttleworth, I'm sure, sees it also as he has decided to ship binary video drivers with the next version of Ubuntu. However, this is a very controversial topic as some feel that in the end it hurts us more than it helps us. However, if we look at FreeBSD/OpenBSD they have basically no restrictions. They haven't attained the support that Linux has. I think that's because of the the GPL. The GPL keeps a fair playing field and thus encourages contribution. In any case, I don't think the GPL is standing in the way of beating Windows. Apple has been trying for some time with a superior product and they haven't made much of a dent either. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From microman at cmosnetworks.com Fri Jan 5 05:34:32 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Fri, 05 Jan 2007 00:34:32 -0500 Subject: [K12OSN] needed: recommendations for Linux flavor with ongoing support In-Reply-To: <1167943353.16197.123.camel@oldmoola.futuresource.com> References: <151198.24756.qm@web32801.mail.mud.yahoo.com> <459BD7FD.9050003@cmosnetworks.com> <20070103114306.2d274fd3@laptop.thesizemores.us> <459BE194.7030609@maltzen.net> <1167844454.7355.22.camel@oldmoola.futuresource.com> <459BF215.8020502@maltzen.net> <459BFEAE.50709@cmosnetworks.com> <1167865073.8934.6.camel@oldmoola.futuresource.com> <1167943353.16197.123.camel@oldmoola.futuresource.com> Message-ID: <459DE368.9040305@cmosnetworks.com> Les Mikesell wrote: > On Wed, 2007-01-03 at 18:32 -0800, Robert Arkiletian wrote: > > >> The point is, of all the distros out there only SuSE has implicitly >> admitted that it is violating M$ IP by accepting a covenant for it's >> customers that states M$ will not sue them for any IP violations. >> > > That's not at all clear - and Novell has explicitly stated the > opposite.

I'm just realistic about what what it can never do as long as software patents and hardware vendors that can't, for various reasons, release GPL'd driver code continue to exist. It doesn't make sense to ever expect legal and complete hardware and multimedia support to be distributed along with GPL'd components even if there are an assortment of ways you might assemble some of those things together yourself. Of course much of what a k12ltsp system includes (X, perl, apache, sendmail, etc.) are covered by licenses less restrictive than the GPL. > If you're convinced that you're at legal risk for using > GNU/Linux or any other GPL'd software such as Samba, then you're free to > go to Windows or Mac OS X. As a matter of fact, I do use use Windows some at work and OSX at home. If you can afford it, I think OS X is the best starting point because there are no restrictions on what the vendor can include in the box for your convenience and you can easily add any missing free software yourself (although samba is already there...). I'd prefer to see more and better competition to Microsoft, though. My main complaint about the GPL is that by preventing distribution of all the components that you need together it keeps any Linux distro from being competitive as a desktop system - and has probably thus made more money for Microsoft than any other single thing. -- Les Mikesell les at futuresource.com From les at futuresource.com Fri Jan 5 07:33:20 2007 From: les at futuresource.com (Les Mikesell) Date: Fri, 05 Jan 2007 01:33:20 -0600 Subject: [K12OSN] needed: recommendations for Linux flavor with ongoing support In-Reply-To: References: <151198.24756.qm@web32801.mail.mud.yahoo.com> <459BD7FD.9050003@cmosnetworks.com> <20070103114306.2d274fd3@laptop.thesizemores.us> <459BE194.7030609@maltzen.net> <1167844454.7355.22.camel@oldmoola.futuresource.com> <459BF215.8020502@maltzen.net> <459BFEAE.50709@cmosnetworks.com> <1167865073.8934.6.camel@oldmoola.futuresource.com> <1167943353.16197.123.camel@oldmoola.futuresource.com> Message-ID: <459DFF40.8060807@futuresource.com> Robert Arkiletian wrote: >> I'm not sure anyone can say that with any confidence, given the >> state of US patent law and the number of patents held by MS.

Ensuring that the development was done independently and no code was copied is enough to avoid problems with copyright violations but patents are different. They cover the process whether you copy it or re-invent it with no knowledge of the covered version. >> I think you missed the other half of the arrangement.

They might: Novell has its own patent portfolio that may include what came with its purchase of AT&T UNIX. It is common for large companies to make broad cross-licensing agreements just because it is cheaper than having to worry about problems and raises the bar to competition from smaller startups. I think this one has just been overblown in the news. >> Samba is really only interesting to someone running Windows anyway. >> If the GPL didn't prevent people from distributing all the components >> you need together, we might have had some real competition to >> windows by now and made it irrelevant. > > I can see your point of view Les.

I'll agree partly in that IBM and a few other large companies might not have invested so much in Linux if the GPL did not restrict how that work might be distributed. However, my take on Linux vs. *BSD is that the popularity (and thus the subsequent development effort) was established much more by the timing of the RH 4.x release which was the first thing you could count on to install by dropping a CD into about 90% of the PCs around at the time, and also by the effect of the AT&T vs. Regents of California lawsuit regarding the *BSD code instead of the license terms. What happened was that vast numbers of people tried that RH CD and got something working before they realized just how bad the code was - and then some of them started fixing it... If you don't agree with that point of view, just wade back though the source changes on some of the programs like bind and sendmail to see how much was really wrong back then - or try installing one of those on an internet-connected box and see how quickly it gets hacked. > In any case, I don't think the GPL is standing in the > way of beating Windows.

Apple sells hardware and isn't really interested in selling an unbundled OS so it isn't a good indication of what someone could do in that market with an equivalent product. Even at that, I maintain the logs for some large web sites used by stock and commodity traders and I see 2 to 3x the hits from Macs as all the other unix/linux versions identified in the logs combined, so I don't think you can use Apple or its bsd base as an example of doing something wrong compared to Linux. -- Les Mikesell les at futuresource.com From dtrask at vcsvikings.org Fri Jan 5 13:35:09 2007 From: dtrask at vcsvikings.org (David Trask) Date: Fri, 05 Jan 2007 08:35:09 -0500 Subject: [K12OSN] very unexpected In-Reply-To: <459D68A0.8070001@paasda.org> References: <459D63CC.9030702@paasda.org> <459D67B2.6000508@maltzen.net> <459D68A0.8070001@paasda.org> Message-ID: "Support list for open source software in schools." writes: >Yes..google-earth that puppy :) GORGEOUS view of Mt.

I think it's a mistake for Fedora to not include KDE in the main distribution. Gnome & KDE both been able to easily fit on the DVD image. I've been a fedora/redhat user since redhat 5.1, but this move makes kubuntu look a little more attractive. Sure, someone will spin a fedora KDE ISO, but ubuntu already has a KDE community with kubuntu. After reading the full thread on the fedora list it appears that a few others agree this is a bad idea, but the powers that be are pretty much interested in keeping it "Gnome centric" Luis Dan Young wrote: > -------- Original Message -------- > Subject: Fedora 7 > Date: Thu, 4 Jan 2007 14:50:32 -0500 > From: Bill Nottingham > Reply-To: Development discussions related to Fedora Core > > To: fedora-devel-list at redhat.com > > It's time to bite the bullet. > > There will be no more releases of Fedora Core or Fedora Extras. > > Wait!

Judging by the other responses I may be reading this question wrong. The way I read it is that your server will basically be stationary and you'll simply be bringing a new internet connection into your server room at the same time as your old one, then phase the old one out once your sure your new connection is completely operational. I have found in the past that 2 network cards on different internet connections can make things get a little stupid. Instead, every time I make a move like this I simply lower my DNS TTL to 1 hour. That way the maximum time your DNS will take to renew after the change is an hour. Then I look through all of my configuration files to be sure that either they reference eth0 or localhost or 127.0.0.1 and then quickly note which ones reference my actual external IP. Don't forget to look through your webmail conf, your php conf, sql conf, or any other confs that Postfix may be calling on. They will all need to be updated. Once you have a list of which confs need the IP change you can make the switch in a matter of minutes. I basically go off the fact that any mail server trying to send to my server has a retry queue. I figure if my server is down for 30 minutes or so, I still won't miss any messages because the sending server will continue to retry, and if for some reason I am not back up in time, at least the sender will get a failure notice (though they never seem to understand them :-). So once I have both connections, I shut down postfix, make my DNS changes, run through all noted configs and change the IP, switch the Internet connections, change the servers IP, then reboot. If I really want to speed up local activity (since that is where most of our customers reside) I call our local IP and ask them to refresh their DNS (we have a home grown ISP here so they are easy to talk into things). With that sequence everyone should be back on the server within an hour max with no messages lost. If you really want to try and shorten things up. Make your TTL change a week ahead of time. Then you know the whole world is on a 1 hour max TTL when you make the change. Then make your DNS changes about 30 minutes before the shutdown and switch. That will almost ensure you a maximum downtime of 30 minutes. And if a couple sending servers get your new IP 15 minutes early or something, since there is no server present yet it should just go in a retry queue and come through once you get things running. Couple all of that and make your changes at 2am or something and about the only email you may loose is some SPAM. I am sure this is not the "PROPER" way to make the changes, but it works for me. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

Both resolutions resulted in the login screen appearing, but when I try to log in it goes black then comes back to the login screen - doesn't reboot, just back to the login. I tried to put back in the VESA and the 4096 statements, but the Xserver crashes again. As far as the other machines are pulling their names - I can see when I do a "w" I see the other users logged into ws131. As far as the ones I am having trouble with, I don't know how to see their names other than when the DHCP kicks in I can see the static IP being assigned.

Fedora is primarily a GNOME distro and they're planning a subproject to distribute a disc with KDE. I fail to see the difference. In fact, I think a "Fedora KDE" could be much improved over the existing situation. Those who are passionate about KDE can form a community around the Fedora KDE efforts and put their expertise to work. It's evident from fedora-devel that there are many such passionate users.

There's a part in that file that says the following: # Run preferred X display manager preferred= if [ -f /etc/sysconfig/desktop ]; then . /etc/sysconfig/desktop if [ "$DISPLAYMANAGER" = GNOME ]; then preferred=gdm elif [ "$DISPLAYMANAGER" = KDE ]; then preferred=kdm elif [ "$DISPLAYMANAGER" = XDM ]; then preferred=xdm fi fi Now, in the part where it checks $DISPLAYMANAGER for GNOME, just tweak that to kdm instead of gdm. Then, so that the new display manager (kdm) takes effect, just do an init 3 followed by an init 5, and that should do it. --TP -------------- next part -------------- An HTML attachment was scrubbed...

I don't have any good suggestions, however I know I have seen good discussion on this list in the past. I just quick added to the subject to help others chime in. On another note, I helped set this school up when it started. Since day one they have used nothing other than K12LTSP for all their needs. It would be awesome if you guys could help them get a good linux based grading system.

I will take a hard look at the config files that you mentioned. Regarding DNS TTL, I may have trouble coordinating the changes because I cannot directly update our DNS pointers. I need to have Cox personnel do it. If I do not need to make any changes to the config files, can you expound at all about "a little stupid" regarding the connections to two ISP's?

I need to have Cox personnel do it. If you don't have control over things it may be tough to convince an ISP to reduce the TTL. You may want to make your change then at lunch or something and just let users know that the server may be down for a couple hours in the evening then make your changes at night. If you can, check the remaining TTL of the common ISP's in your area. If ISP 1 expires in 6 hours, ISP 2 expires in 8 hours, and ISP 3 expires in 4 hours, making your DNS changes 6 hours ahead of time may cause the least amount of downtime. I don't have a recommendation for a good way to check for this any more. The programs I used to use were windows based and I don't have a good suggestion for a way to check this under Linux, but it should be simple (anyone?) > If I do not need to make any changes to the config files, can you expound > at all about "a little stupid" regarding the connections to two ISP's? I left "a little stupid" as vague on purpose. It seems to me that every time I have tried such a thing my machines get "a little stupid" when trying to get to the internet, almost like at times they are not certain which path to take, but I leave that vague because it still doesn't make sense to me why it doesn't always work since I only have one gateway. But if any of your config files reference eth0 or your external IP, you may not be able to tell them to listen to eth0 and eth1 and to external IP 1 and 2. Again it most likely depends entirely on which programs you are using with postfix and how your postfix is configured. I still prefer on late night change overs, getting ahead of DNS, and relying on mail queue's to prevent lost messages. Seems the least muddy to me. I make switches like this quite often, and I have absolutely no problems as long as I give my config files a good once/twice over for how they listen and stay ahead of my DNS. And if I make my change over in the middle of the night with DNS changing shortly before that, there really isn't many if any messages being sent at that time of night anyhow. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

I've seen cases (one just the other day as a matter of fact) where ~/.gconf gets hosed up and when I try to login, it just keeps sending me back to the login screen. This usually happens when I'm messing around with screen resolutions and such. With a brand new ID, you won't have any conflicting settings already in existence.

I do like that it has both desktops, but I realize that adds some constraints that others may not want to deal with. As long as it's easy to add kde, I think that's okay.

I need to have Cox personnel do it. If you can have it changed twice, add the new address as a 2nd equal-weight MX ahead of time. Senders will always try both if one fails so for the transition you can answer on either. After the cutover, have the old one removed. MX records only apply to smtp senders though. If you have people connecting to pick up email with POP or IMAP on the public address they will have to wait until the A record changes in DNS. > If I do not need to make any changes to the config files, can you expound > at all about "a little stupid" regarding the connections to two ISP's? You can have multiple addresses (even on a single NIC), but you will only have one default gateway and return packets don't track the inbound path so you'll often be sending back the wrong way. Normally this will work anyway, but you can have some problems. -- Les Mikesell les at futuresource.com From dhuckaby at paasda.org Fri Jan 5 18:28:09 2007 From: dhuckaby at paasda.org (Huck) Date: Fri, 05 Jan 2007 10:28:09 -0800 Subject: [K12OSN] k12ltsp.org error Message-ID: <459E98B9.2030407@paasda.org> Faliled to open configuration file: "/usr/local/etc/Counter/conf/count.cfg" and yes..the actual error message is misspelled =) I was actually looking for a link to the WIKI...any chance of get'n a link to that on the index page rather than the FAQ page? --Huck, being nit-picky From melliott at rpmhd.org Fri Jan 5 18:55:30 2007 From: melliott at rpmhd.org (Michael Elliott) Date: Fri, 05 Jan 2007 13:55:30 -0500 Subject: [K12OSN] Issues with two terminals - xserver fails / Matrox Millenium II Message-ID: <459E9F22.6060804@rpmhd.org> Tried creating a new user ID, same thing happened.

In order to gain critical mass we need to bend the rules a bit, but does that put us on a slippery slope? I don't know. Hopefully not.

I hope Apple keeps gaining market share. I wonder, now that MacOSX runs on x86 arch, if Apple will ever sell their OS to someone like say Dell?

Just wanted to point out that in my system /usr/sbin/gdm did nothing. It just informed me that it has a gdm already running so my action was canceled. Solution for this was to use gdm-stop command :) This stopped the gdm and PS shows that now I have a kdm processes up :) So this means that something happened somewhere somehow. Now I just have to wait until morning to see if this action helped but now I have another question : I used /etc/gdm/PostSession and /etc/gdm/PreSession scripts to execute some commands (like erase home directories and stuff) ... does this now continue to work as I'm using kdm ?

I agree completely, but I'm not young enough to expect them to go away in my lifetime. Nor do I see much of a trend in that direction. So, unless someone buys a patent and releases it for free redistribution, nothing covered can be legally combined with anything covered by the GPL since it permits distribution only if the 'work as a whole' has no additional restrictions. > I believe the main reason M$ did > this deal was to try to reduce Redhat sales by creating FUD that only > SuSE is safe.

What we need is a clear definition of what that 'work as a whole' means in the legal sense. Linus was widely quoted long ago as saying that binary kernel modules were OK, and I think the current popularity grew partly from that. Now he is waffling about it. If a GPL'd kernel isn't going to be usable for everything we need, there are other choices. > Okay maybe it's not an apples to apples comparison. ;) > In any case, I too am seeing more and more Apple notebooks around.

Nice debate Les. While I don't object to buying OSX and the bundle of licensed products it includes for myself, I hate to give up on a freely available OS being able to do all the equivalent things for anyone who can't afford to pay. It just seems bizarre (but predictable) that the driver that Nvidia would like to give away can't be included and that the license that calls itself free prevents it. -- Les Mikesell les at futuresouce.com From petre at maltzen.net Fri Jan 5 21:24:41 2007 From: petre at maltzen.net (Peter Scheie) Date: Fri, 05 Jan 2007 15:24:41 -0600 Subject: [K12OSN] GDM login manager problem In-Reply-To: <046001c73101$ed280620$0301a8c0@lammas> References: <003401c730cd$8ee575e0$c60e10ac@melka> <459E8484.5090007@maltzen.net> <046001c73101$ed280620$0301a8c0@lammas> Message-ID: <459EC219.4060806@maltzen.net> I don't think the /etc/gdm/*Session scripts will run if you're using KDM.

It lasted two trouble-free years until it got discovered by the Windows Nazis and ripped out. During that time, I had the kids choosing GNOME, KDE, or XFce. About half of them chose KDE, since "it's more like XP", and the other half chose GNOME. A couple chose XFce out of curiosity. BTW, I may have lost that K12LTSP server...but, as of recent, I now have THREE MORE in its place! Different sites, obviously. TUX lives. --TP _______________________________ Do you GNU!?

I know what you mean. I have an application that runs under linux. It has been an uphill battle convincing customers that they can live without windows. Once it's installed they wonder why they put with windows for so long. My clients all use Gnome. I would guess it is because that is what I setup for them. They just like that it works. I'm always checking my software against various distros. Fedora so far works the best overall. I have a box setup with K12LTSP to test with now. It is looking as if it will be my new platform of choice. The fat server/thin client setup is ideal for a small office. Just like I explain to my customers you need the right tool for the job. Fedora works great for my clients because I don't have any configuration issues. I use Centos for dedicated server apps like mail. My laptop is running Ubuntu. I know that it would make more sense to just use one distro. I however need to be able to offer support on any of them. All of them still require more than a plug and play install. I'm happy Fedora is merging the repositories. Ubuntu requires setting up additional repositories and tools to make it fully usable. It is not quite a polished as Fedora but giving out bootable/runable CD's is a plus. My son hands them out at school like crazy. Most of the teenagers find it easier when they can just boot a CD and play without doing an install. As a personal note. I would not mind seeing more kids getting their hands on Ubuntu disks. (hint, hint).

Once the kids learn that, being a "Live CD," it won't FUBAR their Windows installations w/ all their games, they seem more ready to try it. When they ask me, "Where's Internet Explorer?", I then, in my best Confucius imitation, answer with the now-venerable KDE saying, "First came the Navigator, then came the Explorer, and finally, cometh...the Konqueror. Remember this, you my padawans, and thou, too, shalt grasp the Tao of Linux." That always gets a laugh out of 'em. :-) BTW, since you like CentOS, there is a CentOS version of K12LTSP. I'm using it right now to type this, and my terminal is an EtherBooting AMD K6-2/450 that I built eight years ago. Server is a dual-Athlon 1.2GHz box w/ 2GB DRAM built three years ago, and still rockin' beautifully. --TP _______________________________ Do you GNU!?

Since you are currently running it, what versions of the OS and LTSP does it consist of and where can ISO images be obtained? I looked on the K12LTSP site and the CentOS site and don't see any CentOS/K12LTSP info. A quick Google search only turns up various forum postings referring to CentOS with LTSP v4.x.x. I did see Eric's one word affirmative response to a query about future K12LTSP/CentOS distributions, but apparently there is a version already released, so any specifics about what is already out would be helpful.

Take a look at the 'EL' versions at ftp://k12linux.mesd.k12.or.us/pub/ K12LTSP/ . I don't know if there's a website with more info, but I believe it's based on CentOS 4. I don't run it myself though.

Virtual machines are perfect for this too. You can set up several distros running on the same physical box under the free VMware server with NFS access to the same resources and connect to them with 'X -query ...' from your desktop. If you can set up freenx on each virtual server, that is even better. The VMware console works too, but not quite as nicely as a direct X connection or the NX client. > Just like I explain to my customers you need the right tool for the job. > Fedora works great for my clients because I don't have any configuration > issues.

We have multiple IBM X235/x236 with double Xeon 3GHz processors outfitted for a failover LTPS configuration at our school (80-100 clients) and are wondering whether we can simplify the configuration by making use of a single server with double Xeon dual core processors (say an X3650 that comes with 2 dual-core Xeon 2.33/2.66 or 3.0GHz) Can anybody testify a configuration with similar loads who made such a swap? I know dual core processors don't have a similar performance as 2 separate xeons at the same speed, but one might wonder with all the threaded apps en memory use in LTSP, that it could stack up to it... I must say I feel a bit skeptical sometimes at the performances quotas that I sometimes see here on the list, since we noticed (even on our glass backbone) that x236 servers with 3GHz processors and 8GB ram fitted are really dropping performance to a slow when 60 people login (2 classes) and start working on office and firefox stuff at the same time. That's why we needed 2 similar servers and we are doing fine now. As soon as the CPU loads get over the 65% peak loads, we get a real drop in performance, but no iowait or memory hogs or anything....

Depending on the apps running (e. g. TuxType), it could also be server bandwidth, but from what you describe, it sounds like you're starting to swap to disk once you hit 60 clients. That will definitely slow any kind of terminal server, including LTSP servers, to a crawl. You might not have any DRAM hogs, but if you've got a bunch of instances of an app running, all using a certain amount of DRAM, that adds up. For that reason, I normally didn't push my servers, which generally have 4GB DRAM, past 30 clients. Since you're only at 65% CPU usage, it really doesn't sound like that's your problem. Also, make sure that you are indeed checking that *all* of your server's CPUs are seeing only 65% usage. By default, top shows only an average between all of them. --TP _______________________________ Do you GNU!? Microsoft Free since 2003 --the ultimate antivirus protection!

When I did the install I knew what ethernet adapter (eth0)I would be using for the client side and edited the ip information accordingly. For what it's worth the other interface (eth1) is specified as 192.168.10.2. It is connected to my private network that is firewalled appropriately. I can connect regular machines to the switch on eth0 and receive DHCP addresses fine and the machines connect to the internet. > > * what type of terminals are you using? This is where the problem gets funky. I am using old IBM 380EZ laptops with 3Com 3CCFE574BT PCMCIA ethernet adapters. The way I always booted these clients with K12LTSP 4.X.X and earlier was to get the wireless_ltsp-3.0.5-i386.tgz package and extract the floppy.img image and either make a boot floppy or copied this image to the harddisk of the terminal and edited the grub boot menu accordingly. I found these instructions on the mailing list here: http://marc.theaimsgroup.com/?l=ltsp-discuss&m=108789847231845&w=2 I have done some experimenting and I have learned that I can successfully boot a client that has a built in ethernet connector when I enable the BOOTROM in the BIOS so the problem seems to be related to the boot image I am using....... I hope that I can resolve this problem because the client/terminals I am using are ideal for my setup because of several reasons...I got them for free, they are real space savers and my daughters don't need to use my wife and my desktops to access their accounts..... Thanks for you help so far.

How has the administrative and teachers in general accepted k12ltsp in your school? I'd like to hear actual "comments". Here is a scenario at our school. Of course most teachers are very offish because " Its not MS$". The last superintendent was very receptive to Linux/K12LTSP, but having consolidated and a new super,I heard was " Well whether you like it or not,it's a MS$ world out there". Enough said. How do you get any farther than that?:(. Also Ive heard "It's free"? Mind turning,,, it must not be worth much:(. Or "How much longer will it be free". You can show all involved the benefits of the Educational software bundled for all age ranges,right out of the box,in K12LTSP,but seems to not offset it,, not being branded MS$. I've found if you told the higher ups its going to cost thousands of $$ to get k12ltsp going they would listen much more. Don't make sense but thats the way it seems. Here's a good point too. I talk to an old timer on the phone for hardware, that is a long time Linux guru,,that had his own business and is a world traveler, He told me that the US would be the last country to "flip" to accepting Linux,because the US is so "commercialized". Im seeing he makes very much sense.:)You people in Europe/Asia/etc, are a step ahead,in thinking i can see!:). Just curious what others have heard when trying to roll out K12LTSP in your schools.

The HD is still under warranty but am wondering how to enable the new HD once it gets here. This is on a sata raid-0 arrangement. Out of all of the calamities we have run into,ive never had to replace just one hd in a raid array. These are on hot swappable server so removing/replacing( in front), is easy. Will i need to go into the raid bios part at bootup on this server and "rebuild raid array"? I dont want to wind up "mirroring" the wrong drive and end up with two blank HD's! This would be my luck!:)... Any info appreciated.

They have been pushing hard for Linux and OpenOffice. The district thinks every family can go out and plunk down the cash for MS Office to do homework with. Most who do have it are using a borrowed copy from their parents work. My oldest son has taken a pretty firm stance. He has linux on a thumb drive and boots it to do his work on at school. While it annoys the tech people the teachers find it amusing. So far the only issue was when someone from the district tech support was in the classroom and decided he was just a dumb kid. My son retaliated by calling him an idiot and rebooted every computer in the district. I had to chat with the principal and we both agreed the guy was an idiot. My son also apologized to the principal and has managed to control himself. I also made a point that he would not have been able to do that if they were using Linux. The biggest issue seems to be with the support staff. They see the loss of windows as a loss of job security. In the evolve or die equation they seem to choose the latter.

Focus on the concept that the software is Free as in Freedom. There is a price for Freedom :). Free Software isn't the same as $0. See also: http://www.gnu.org/philosophy/selling.html Other factors such as labor and support are not $0. Consider support contracts from local GNU/Linux vendors or through a local non-profit if it's available. Perhaps that can give an added sense of realism. Remember that to many, the concept of not paying for software conjures up words like 'Freeware'. People are also brought up the the concept that 'nothing comes for free'. ~ Julian From mrjohnlucas at gmail.com Tue Jan 9 11:09:35 2007 From: mrjohnlucas at gmail.com (John Lucas) Date: Tue, 9 Jan 2007 07:09:35 -0400 Subject: [K12OSN] general acceptance of k12ltsp in schools In-Reply-To: <45A344FF.2080504@cmosnetworks.com> References: <1168306400.20976.2.camel@localhost.localdomain> <45A344FF.2080504@cmosnetworks.com> Message-ID: <200701090709.35714.MrJohnLucas@gmail.com> On Tuesday 09 January 2007 03:32, Terrell Prud?

I also have 20 k12ltsp thins in a building @ 3rd grade. My intention is to do a manual install of the SM client and try wine. You will need sound on your thins. Even if you are using SM @ grade 5 ( no sound ) you will need a sound card to run the installer. Also the course we use most is Math Concepts and Skills. I have not tinked with the Enterprise version. The ability to use thins for SM would make LTSP even better. I heard at one time SM was going flash/web based which would solve our problem.

I have had weird problems when connecting 100MB NIC to 1GB switch ports (hoping for the switch to slowdown) and also problems connecting 1GB NIC to 100MB switch ports (hoping for the NIC to slow down). In both cases things should work, I also get link lights and activity. If you are using an all gig switch maybe try something with a gig uplink for the server and standard 100MB ports for the clients. Also maybe try using dumb switch if your current one is a managed switch. I have found the Dell 23xx line to work great (maybe try a 2324) and they are fairly cheap. If your using the same NICs with both setups and the same clients, I would have to say your problem is with the switch or negotiation. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

I'm trying to make a lab available for more kids to take more classes through Plato, but I am not allowed access to Plato, or the plug-ins needed to make some of the things work with the Plato courses. We are running the web-based version of Plato. Has anyone gotten K12LTSP to work successfully with Plato? According to their specifications it will work on Apple or Windows with IE and Netscape. Most of the classrooms here are running it through Safari, but not everything works (some of the math animations apparently don't work with Safari). I'd like to set up a lab for Plato with K12LTSP in our school, but I want to make sure it will play nice with K12LTSP first.

The blog to which you're referring that describes that BSA audit is called "The Blog of Helios" over at blog.lobby4linux.com, and I read it, too. Ken "Helios" Starks now runs K12LTSP at "Ultra Secret Corporation," so named because they're apparently in pending litigation with the BSA and Microsoft. Everyone on this list should read The Blog of Helios. Starks's story is truly an example of Things Done Right. And he's doing it...WHILE BATTLING CANCER.

So the actual usage per user is less. Look at top to see RES and SHR. There is only one instance of the shared memory allocation for all the users using firefox. So subtract SHR from RES for the actual memory used by the user. > > ( and games, edu apps, drawing, java science... ) > > + 500MB goes to squid (web proxy) which make a big difference !!! > > Nadav :-) > (Bless Eric) > > > On 1/9/07, "Terrell Prud?

I am think now that it has something to do with the script I used to set .doc, .xls, .ppt files as the default for users. Since I am using Ubuntu, I don't have any of the handy-dandy scripts that Eric wrote to ease k12LTSP administration. So I wrote my own. Hopefuly someone can spot a problem and help me work this out. Here's the scenerio: 1) I want all student users Open Office docs to save MS formats by default. I accomplish this by copying information from a template account into the directory of the student at login. The script creates the path to the OpenOffice files in question because they are normally dynamically created when the user executes OO for the first time. If I don't pre-create these directories then the MS defaults aren't copied accross successfuly until the SECOND time students use OO. This is script is called from /etc/gdm/PostLogin/Default. Here's the script #creates the directories ahead of time so that the following scripts always have a place to go sa=/home/VUARD/$USER/.openoffice.org2/user/registry/data/org/openoffice/ sw=/home/VUARD/$USER/.openoffice.org2/user/registry/data/org/openoffice/Office/ mkdir -p $sa mkdir -p $sw chown -R $USER $sa chown -R $USER $sw cp -f /var/oofficeDefaults/Setup.xcu \ /home/VUARD/$USER/.openoffice.org2/user/registry/data/org/openoffice/Setup.xcu #makes the Zdrive the default save location for users by copying the settings from #/var/oofficeDefaults/ cp -f /var/oofficeDefaults/Common.xcu \ /home/VUARD/$USER/.openoffice.org2/user/registry/data/org/openoffice/Office/Common.xcu exit 0 Thanks in advance for any help anyone might be able to render.

GCompris...same as above.

Tux-type/math .. Oh this is fun! But it's getting slower, not faster (as more people loaded it...those are intense power hungry apps) Terminal...what can the kids do with this? (Huck, absolutely anything they want...create files, write programs, create scripts, learn/run almost any program) Where's the anti-virus software? (Huck laughed) All in all I was surprised at how quickly the older ones caught on and got the hang of stuff... and then I demo'd TeacherTool ;) and they were all, Ahhhhhhhhhhhhhh!!! now THAT's what I want!!

Is it linux software raid or handled by bios on the motherboard? You can 'cat /proc/mdstat' to see if you have software raid. If you do, you can 'fdisk -l' the working drive to see the partition size(s), then fdisk the replacement drive to match, then mdadm -add /dev/md? /dev/sd?? where the ?'s would be determined by the array and disk/partition numbers. If it is done at the bios level it is probably different for each vendor. -- Les Mikesell lesmikesell at gmail.com From KEBoone at bcps.k12.md.us Wed Jan 10 10:29:31 2007 From: KEBoone at bcps.k12.md.us (Boone, Kevin E.)

Usually you hit a key during boot-up to get into the raid setup and there is some kind of step where you 'initialize' a disk and then add it to the array to create a volume. It should know which disk has not been initialized when you boot after adding the new drive. They usually don't rebuild automatically unless you set up a hot spare ahead of time, so you have to tell it to add the new disk to the existing array or volume. -- Les Mikesell lesmikesell at gmail.com From petre at maltzen.net Wed Jan 10 14:34:08 2007 From: petre at maltzen.net (Petre Scheie) Date: Wed, 10 Jan 2007 08:34:08 -0600 Subject: [K12OSN] Neoware thinclients In-Reply-To: References: <4024.192.168.1.2.1168393379.squirrel@192.168.1.2> Message-ID: <45A4F960.3000500@maltzen.net> I think the one that's getting all the attention is the $99 TU system, on the top left part of the homepage.

No problem there. The issue with my current configuration is that the mirror list is fetched from a single server, such as: mirrorlist=http://k12linux.mesd.k12.or.us/mirrors/k12ltsp-6.0-$basearch If you can't get to http://k12linux.mesd.k12.or.us, you can't get to the mirrors. I'll look into setting up a virtual server, say http://repos.k12linux.mesd.k12.or.us, and putting the mirrorlist there. I'm already running all the traffic through a Foundry L4 switch, so it shouldn't be too tough to configure transparent fail-over between two servers. -Eric From nils at breun.nl Wed Jan 10 16:32:53 2007 From: nils at breun.nl (Nils Breunese) Date: Wed, 10 Jan 2007 17:32:53 +0100 Subject: [K12OSN] K12LTSP ftp/yum/rsync server down In-Reply-To: <45A512FB.20107@mail.mesd.k12.or.us> References: <45A50CD8.2080909@mail.mesd.k12.or.us> <45A512FB.20107@mail.mesd.k12.or.us> Message-ID: Eric Harrison wrote: > Yum has great support for mirrors.

Wouldn't it be a good idea to ship a k12ltsp-release package with a mirrorlist in it and use mirrorlist= in the repo file? That way people always have their mirrorlists and you can push updated mirrorlists by creating a new version of the k12ltsp-release package. I believe I have seen other repositories do this.

Mirroring the repositories, in the current design of K12LTSP, requires a huge commitment of storage space and effort. In the past, trying to mirror the repositories has caused me more problems than it has solved - and the problem set is now 4 times larger considering there are four current versions of K12LTSP vs only one in the past. Guess what I've been working on the last couple of weeks? Making K12LTSP much easier to mirror and easier on the mirrors ;-) >> The issue with my current configuration is that the mirror list is >> fetched from a single server, such as: >> >> mirrorlist=http://k12linux.mesd.k12.or.us/mirrors/k12ltsp-6.0-$basearch >> >> If you can't get to http://k12linux.mesd.k12.or.us, you can't get to the >> mirrors. > > Wouldn't it be a good idea to ship a k12ltsp-release package with a > mirrorlist in it and use mirrorlist= in the repo file? > That way people always have their mirrorlists and you can push updated > mirrorlists by creating a new version of the k12ltsp-release package.

I believe that CentOS is using DNS to deal with this, which is pretty slick, but requires the mirrors to be consistent in their file system layout. -Eric From timothy.hart at gmail.com Wed Jan 10 17:07:10 2007 From: timothy.hart at gmail.com (Timothy Hart) Date: Wed, 10 Jan 2007 12:07:10 -0500 Subject: [K12OSN] OLPC Laptop On Sale To Public Next Year Message-ID: <464c38cc0701100907h46675303h84bbc2dd79c22201@mail.gmail.com> Link to News Story: http://news.bbc.co.uk/2/hi/technology/6246989.stm Tim -------------- next part -------------- An HTML attachment was scrubbed...

I have come accross several that have been able to load shockwave under WINE. Here is a link to a howto running Ubuntu and the Windows version of FireFox http://www.ubuntux.org/shockwave-player-ubuntu-linux Hope this helps.

But you could run "top", and see which programs are using the most CPU, then switch it (I believe you press "M" while it's running) to see which programs are using the most RAM (on the assumption that the offender is swapping out a lot). If I had to guess, I'd suspect spamassassin (I've seen it gobble lots of RAM over time).

It has a big advantage on the client side in that you can use a local caching proxy and all the machines behind it will used cached copies of the updates if they have already been downloaded.

To see this interview summary with the original links, go to http://www.stevehargadon.com/2007/01/interview-with-jim-hirsch-at-plano-isd.html "The students, when they leave our classrooms, self-manage their own learning, their own collaboration. As we bring those kinds of environments within a classroom setting, how do we have that blend, if you will, of teacher-management and student-management? That is perhaps our greatest challenge right now: to what degree can we place the responsibility of learning, and the management of that learning, on the individual student? And to make that work, our parents have to be partners, they have to have input into how that will work, and they have to believe that that's also the environment that their children are functioning [in] outside of school... so let's see how we can make that work inside of school." "These students today are very adept at working together, to find information, and to create knowledge. What they're not adept at yet is knowing what questions are the best ones to ask before they go looking for that information. And yes, I firmly believe, that in my thinking of reform, that our new collaborative tools, our web 2.0 tools, will make the difference in making that happen in classrooms." Jim Hirsch is the Associate Superintendent for Technology and Academic Services at the 53,000 student Plano Independent School District. I visited Plano ISD in November when we held a 2-day workshop on Moodle, and I remember being struck by the superb training facilities that they have there. I interviewed Jim last week, using an article in eSchool News on "Education 2.0" as the starting point for the discussion on school reform and technology. Because much of the discussion on "School 2.0" or "Education 2.0" usually comes from the grass-roots level of teacher-practioners who feel that the school administration doesn't support the use of new technologies, I thought it would be interesting to interview Jim. Jim comes across as determined, pragmatic, organized, focused, and methodical. He is articulate, and I felt that every answer he gave to my questions had been thought about and spoken by him before. Jim has been an outspoken proponent of "Open Technologies," which is not the same thing, necessarily, as "Open Source" or "Free and Open Source" software, so I was prepared to listen carefully as to how he discussed those topics. Notes: * In the eSchool News article, Jim is quoted as predicting that within five years "not a single desktop [at Plano] will carry the image of a proprietary school software program." They are aiming to totally move away from their dependence on proprietary client-based software, and moving into a web-based sphere of development. They want to extend learning outside of the school walls, including to devices that most used by their students and their families--including cell phones. Much of this, he believes, will be possible through Open Source or Open Technologies. * Usually I hear from teachers that it is hard to implement web and collaborative tools in the classroom because the districts are restricting their use. I asked Jim what was happening in Plano, since the push is coming from the district side. He replied that they are two years away from becoming a "majority minority" district, and they've been in quick transition for the last few years, meaning that they are coming to the realization that they can't do business as they have done in the past to help all of their students to receive high-quality instruction to to achieve. Their approach is very pragmatic, as they can't afford to use technology that doesn't accomplish that. They don't want to wait for the teacher ground-swell--they want to figure it out now. * How is this different than the technology promises of the last 20 years? He agrees that often technology has been placed in classrooms with "hope" but without "planning." He thinks more and more schools are thinking about how to truly leverage their resources to actually make a difference. Low cost technologies with high impact are starting to get adopted, like wireless keyboard in the classroom that can be passed around and be used by the students to impact what's being presented. Much less expensive than a digital chalkboard, and more effective. * Even their low-income families have cell phones (in fact, they more often have a cell phone than a land line, which requires more stability). So then the challenge is to figure out how to use these technologies that they have access to. * To implement student-centered learning takes a lot of planning and training. Training is a big part of changing from students being "given knowledge" to "participating." * Parental involvement--by and large the parents are interested in being more informed and more involved in the student learning. Plano have put into place a system that sends an email to parents based on "trigger points" that they get to define. They are trying to make the parents more of a partner in the learning process. * They involve their teachers "intimately" in the curriculum development process, and they provide teacher-leaders with the most up-to-date tools and information that they can--both to get input from their teams and to provide initial training and support. This involves hundreds of teacher-leaders. * How do you figure out what new technologies to focus and train on? Until the technology gets out into the hands of the teachers, they don't know how they will be used or how successful they will be. I was very impressed with this mind-set from Jim. They have to be agile enough, and open to input from the teachers, to figure out what tools and training actually work. He uses the word "trust" here--that the teachers have to trust that their input will make a difference, so that they are willing to give it. * The technologies getting most quickly adopted are those that allow the students to participate and collaborate, like "large group viewing" from a projector. Both teachers and students have said the same thing--the students get a chance to deliver their creation in front of the classroom. * They are trying not to draw a distinction between Open Source / Open Technology and proprietary software based on cost, but rather on use and the strength the application brings to learning. * Open Office: are using in a limited number of classrooms. It is part of the goal to move away from proprietary desktop software, but Microsoft Office-built parts of their curriculum make that hard to do immediately, particularly PowerPoint presentations that don't play well in Open Office. They don't want any unknown holes in their curriculum, so have to identify those resources and then determine what they are going to do. * Much easier to implement has been the Free and Open Source program GIMP, the graphical image program. They can roll out GIMP very quickly and very easily in a mass implementation, because the dependencies on previously-built training materials aren't there. * I asked Jim if it was appropriate to link the new web technologies and school reform. He does believe that the classroom environment and teaching strategies do need to be reformed. Our students of today, because of access to media, the internet, and instant messaging "no longer rely on a historical perspective to make decisions." The rely much more on their friends and what they can find on a search engine. They are good at getting information, but don't know what questions to ask before looking for the information (and maybe in evaluating that information). He does think the Web 2.0 tools will really help in the classroom. * Blogs and wikis: they are at the infancy stage in using these. When commercial-free sites became available, teachers asked to use them. Rather than have the teachers go out and use different services, they have committed to providing the resources internally. This means that they have moved more slowly than some of the early adopters might have liked, but they have actively involved those teachers who are most interested in helping to make the decisions about how to bring blogs and wikis into the curriculum. And once they are in the curriculum, they will become systemic. Producing their own resources for blogs and wikis will also give them the ability to manage them "in the way that is most appropriate" for their community and make decisions about student safety. Currently, all blogs being used are being kept internal and not available to the outside world. (They use Wordpress as their blogging platform.) * Moodle--all their new development on on-line courses are now being done on Moodle. They have been doing online courses since February of 2000. They want to move all their existing content to Moodle and wish they had a utility to do that (heads-up, Moodle consultants!). * How are their proprietary vendors responding to these initiatives? They all ask the same first question: have we done something wrong? He tells them no, but that they need to consider how their product and service might work in the new environment. Removing proprietary desktop software doesn't mean that Plano won't have products and services that are needed from vendors--it just changes the model of what is paid for. * It's not just about instructional technology, but also involves administrative systems: they are working on the development of their own ERP system, looking for something totally web-based. * The big concern about web-based applications for students is what happens if the network goes down. We also talked about data privacy and the ownership of data, as well as the local hosting of services. * They don't use Linux on the desktop "at this point in time." They do use it on their server farms. They have 120 units of ultra-mobile units on order that will run Linux. It is a direction that they are "definitely having as a requirement." * They have 31,000 desktop computers, one computer for every 2.2 students. But they are not pushing for a 1:1 environment. Every student needs teacher interaction every day, and collaboration doesn't require computing. You can overdo the technology on occasion, but the reverse is worse. He tells the touching story of one of their 8-year-old students guide a parent through the process of helping her parent fill out an online job application at a kiosk. "It's incumbent upon us in public education to provide our students with experiences that allow them to function in their natural world--and that includes technology." * He's noticed that many of their students are moving from MySpace to FaceBook. * Jim doesn't blog, but he does track them and tries to contribute. Interviewing Jim was quite interesting. Please comment and let me know what you think.

I have eth0 plugged into an unmanaged, consumer grade gigE switch. I have several different thin clients plugged into the switch. I asked the list previously for suggestions about how to check what actual network performance I'm getting. Someone suggested I run TuxType fullscreen while running IPTraf. When I run IPTraf on eth0 I see around 50Mb/s of traffic with one client running TuxType. I've gotten two clients gotten 2 clients going playing battle for Wesnoth and gotten the traffic on the server up to about 70Mb/s. So I know the NIC on my server can serve more than 50Mb/s, but I thought that TuxType fullscreen took around 70. At 50 Mb/s, the performance in TuxType is pretty terrible. The screen redraws are jerky, the letters don't come down very fast or smoothly. There's a ton of latency when selecting even from the menu to start the game. What does this tell me about where my bottleneck might be? CPU and RAM are way below 50%. (I can't remember the exact numbers) No swapping. It seems like all that's left is disk, but I can't imagine that Tux or Wesnoth is that disk intensive in the midst of a game. Or the wiring to the clients. Any thoughts about how to track this down? My clients are kindof whimpy, do I need more than 4 megs of video ram? Does the type of video card make a difference? What's best? Better nics in the clients? I'm kindof confused. I thought you could get good performance from dumpster hardware using K12LTSP. By and large I'm very happy with my thin client setup, but this is one area I'd like to improve. Just to be clear, my main problem is slow screen redraws during fullscreen games where the whole screen is moving. I get the same effect when I scroll a web page with the browser window maximized. It just scrolls slowly and choppily. Any ideas what's the limiting factor here?

Wherever you see 192.168.0, replace it with 192.168.1. dhcpd is smart enough to know to hand out 192.168.1.0/24 addresses only on the interface in that subnet (I'm assuming you'll use 192.168.1.254 for your server's new NIC). Also, make sure that you have a "next-server" setting in each of your DHCP scopes that points to the appropriate NIC (192.168.0.254 for the original scope, and 192.168.1.254 for the second, new scope). That's how your clients will know where to TFTP-boot from. For /etc/hosts, you get to essentially replicate everything in there, in a way that you avoid name/address resolution conflicts. You know all those entries that look like this? 192.168.0.9 ws009.ltsp ws009 Well, you'll need to make 254 more entries to account for the clients on the new (192.168.1.x) NIC. But you can't have two "ws009.ltsp" entries pointing to different addresses? What do do? My solution was to tweak the names so that my /etc/hosts has entries like this: 192.168.0.009 ws0009.ltsp ws0009 192.168.1.009 ws1009.ltsp ws1009 192.168.2.009 ws2009.ltsp ws2009 In my case, I simply added a digit to the hostname, specifically, the third octet of the IP address. A simple little script will generate this for you: ****** CUT HERE ****** rm mynewetchosts.txt for octet3 in `seq 0 2` do for octet4 in `seq -w 1 254` do echo '192.168.'$a.$b' ws'$a$b'.ltsp ws'$a$b >> mynewetchosts.txt done done ****** CUT HERE ****** Then, after backing up your original /etc/hosts (/etc/hosts.bak, perhaps?), just copy this mynewetchosts.txt over to /etc/hosts. Finally, we deal with /opt/ltsp/. In my case, since my clients are different CPU architectures, I needed /opt/ltsp/i386 (comes with K12LTSP), /opt/ltsp/ppc, and /opt/ltsp/sparc. Each of these subdirectories served a different subnet. Well, since all of your clients are x86, then you get to have more than one "i386" directory tree. Why? Yes, the binaries are the same, but you need to tell your clients which IP address to talk to. Just copy your entire /opt/ltsp/i386 directory over to, say, /opt/ltsp/i386-1. Head on into this new /opt/ltsp/i386-1, and tweak lts.conf such that wherever you see "192.168.0", you replace it with "192.168.1". There should be only a couple of spots, and, IIRC, the critical one is the "SERVER" variable. Note that, in your second DHCP scope in /etc/dhcpd.conf, you will need to tweak "option root-path" to point to /opt/ltsp/i386-1. In my /etc/dhcpd, I've got three scopes, one pointing to /opt/ltsp/i386, one pointing to /opt/ltsp/ppc, and one pointing to /opt/ltsp/sparc. The reason you have to do that is because this is the directory that your LTSP clients use to do the pivot-root. In your case, each of your /opt/ltsp/i386 and /opt/ltsp/i386-1 will be pointing to a different IP address (NIC) on your LTSP server. Once you're done, you should be able to turn up your second NIC, bounce dhcpd, and have clients netbooting on your other subnet. HTH, --TP _______________________________ Do you GNU!?

I cleaned out things in /var/lib/nfs -- but made sure to re-create the folder structure, because it's VERY crucial to create the folders... I also fsck'd my /home partition, and did a little "server get better" dance in the server room. I rebooted everything, to make sure it came up on it's own, and things appear to be working well this morning. I did get a "files can't be locked" error on on eMac that hadn't been rebooted. After reboot, the eMac didn't complain about file locking. I also found that I had a cron job running every minute to fix permissions on a shared folder. It was a recursive chmod command, and there are now quite a few files/directories in the share. I bumped that down to every 10 minutes, so maybe that will help with performance issues a bit. If I can limp through this year, I'm pretty sure next year I'll have my OSX machines mount home folders in a different way (via netatalk maybe, but I'll have to get LDAP working on either an OSX server or a Linux box) Thanks for the well-wishes, and the email I got offlist as well. -Shawn On Jan 10, 2007, at 12:48 PM, Huck wrote: > GOOD LUCK SHAWN! ;) > > Shawn Powers wrote: > >> If nothing else, please wish me luck. >> -Shawn > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see > --- > This message checked for SPAM and Viruses by MailFoundry. > If this is SPAM, please forward it to spam at mailfoundry.com -- Shawn Powers Technology Director Inland Lakes Schools PHN: 231-238-6868 x9174 FAX: 509-356-7024 spowers at inlandlakes.org Work Website: http://techcorner.inlandlakes.org Personal Blog: http://www.brainofshawn.com ---- The views, opinions, visions, thoughts, comments, sarcastic whims, forecasts, poetic outbursts, cynical wit, future plans, implementation ideas, OS preference, curricular insight, ice cream preference, or anything else I might infer are not the views of Inland Lakes Schools.

Each user and group has a number. The names are only to help us humans keep them all straight. Anyway when you create a user, the number is assigned automatically unless you specify it. If you create users in a different order on the new machine than on the old machine, the user numbers won't match up. You probably now have a user "bob" whose home folder is owned by "mary". Or maybe bob's home folder is owned by "502" or some other number (a number which doesn't have an associated user on the new system). "cat /etc/passwd" will show you the user and group numbers, so you'll understand what I'm talking about. If you want to fix bob's home directory permissions, type this: chown -R bob.bob /home/bob This will assign owner "bob" and group "bob" to every file and folder in /home/bob. (First make sure that the group "bob" exists and that's the group you really want to assign). Alternatively: chown -R bob.students /home/bob would assign owner "bob" and group "students" to every file and folder in /home/bob. -Rob --- tkathan at charter.net wrote: > Recently reinstalled server.

In big school boards, the number one reason why Linux isn't adopted is because the IT people are scared shitless. For some stupid reason they think they will lose their jobs, so they do anything possible to keep Windows around. I find this sad and amusing at the same time. The _IT_ people are afraid of _IT_. The _IT_ people are afraid to learn about new _IT_. In every private sector IT job I've had, I've been expected to learn about new technologies all the time - it's _part_ of the job! The other thing strange is that if school IT people actually got some Linux training, they would see their usefulness shoot through the roof, along with their salaries. I don't bother with big boards anymore - waste of my time. I'd like the business, but the politics and fear keep the people in charge from doing anything that will benefit the students - and Linux will certainly benefit the students. -- Kanwar Ranbir Sandhu Linux 2.6.18-1.2869.fc6 i686 GNU/Linux 23:51:23 up 6:03, 1 user, load average: 0.35, 0.45, 0.34 From carl at snarlnet.com Fri Jan 12 07:54:37 2007 From: carl at snarlnet.com (Carl Keil) Date: Thu, 11 Jan 2007 23:54:37 -0800 Subject: [K12OSN] Getting sound to work with LTSP-esd-alsa Message-ID: <45A73EBD.205@snarlnet.com> Hey, Thanks for the reply.

Unless changes are made, your LTSP server is not set up as a router and won't pass packets from the "inside" network to the "outside" network.

K12LTSP should come with a script to do all of this, though. Try service nat on to start it and chkconfig nat on to make it start automatically at boot up. Your other routers shouldn't need to know about the eth0 address range because outgoing packets nat to the eth1 address.

Usually, 'ifdown eth0; ifup eth0; service NAT restart' fixes it. And yes, the K12LTSP server is setup to automatically act as a router, and handle all the networking correctly automatically. I just have a tendency to unplug things and mess things up temporarily.

On all but one routing has always worked perfectly for any Windows PCs connected to the "internal" subnet. The server this has never worked on, though, is one where I know for sure I did not have either NIC (it has two) connected during the K12LTSP installation.

Mind you, 'connected' just means the NIC is connected to a switch; there doesn't have to be any other devices connected to that switch.

The nat service is pretty simple. If you strip it down, this is all it does: PUBLIC_ETHERNET="eth1" iptables -t nat -A POSTROUTING -o $PUBLIC_ETHERNET -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward It doesn't care if the interface is up or down, what the ip address is, etc, etc. The only configurable item is the interface that is nat'd.

Thanks for the info! I'd be nice to have this working. Though, frankly, it's not critical since, with this particular server (serving a single classroom) the Windows PCs connected to its subnet are already using NX Client to run apps on the server and, as needed, access the Internet.

(either by clicking on the "Install Acrobat" icon or running /usr/sbin/get.acrobat) I can update the root-desktop-urls to point to the latest version of Adobe Reader, but "yum update" will only update the root-desktop-urls package - it won't automatically fetch the updated Acrobat as well. So I'm going to try a new approach. The latest root-desktop-urls package for K12LTSP 6.0 has a new script, /usr/sbin/get.acrobat-upgrade, that is automatically executed after the package is installed. If the upgrade script sees that you have the AdobeReader_enu package installed, it fetches and installs the latest version. I'll do this for the 5.0 & 4.2.3EL versions as well, once I'm sure this really is as safe and sane as I think it is... In the meantime, you can go to http://www.adobe.com/ , click on "get Adobe Reader", choose "rpm", click on "Continue". When the download is done, you can open up a shell and run "rpm -Uhv AdobeReader*rpm" to install the new package. -Eric From atmlogic at kmts.ca Sat Jan 13 01:22:53 2007 From: atmlogic at kmts.ca (ATM Logic) Date: Fri, 12 Jan 2007 19:22:53 -0600 Subject: [K12OSN] Failed software raid 5 In-Reply-To: <1159414533.23295.60.camel@merlin.localnetsolutions.com> Message-ID: <004d01c736b1$5a033760$f800a8c0@ATMLogic.local> Just wondering if anyone on the list may be able to point me in a good direction for getting support on a failed software Raid5 (3 drives)?

I've been using Qemu for over a month in one computer lab on Windows boxes that were bought new one year ago. This sounds like a lot of extra work,but I have come to find out it was worth the "experiment". This would be for the people that cant "give up Windows fat clients". I installed a FC5 install via network of the K12ltsp CD's. Then added the qemu & kmod-kqemu / accelerator rpm's. Then installed Winder's Xp pro onto the fat clients.The nice thing about this arrangment is Qemu has an overlay option,so if someone kills the system files,or has "lost" icons,or whatever you simply remove the overlay,to original windows install then re-create your overlay and the machine is going again. Much the same as system restore only a one click,and going again,affair! Takes all of about 2 minutes. Really no need for anything like Deepfreeze,,either with this setup. I tested on several pc's before diving into this. I found you should have a minimum 0f 376mb ram,,then start emu with the -m 256 switch for the windows guest OS. You'll never get quite the response running emulation,,as you would "hardware" but is very acceptable. All sound cards are the same this way,as well as video, nics, etc. I just made up a startup script to start Qemu at FC5 login, and made the FC5 to auto-logon,,so bootup time ends up being about 120 seconds .versus a normal windows bootup of about 45-50 secs.You are booting FC5 ,then Windows on top of it afterwords. Some people may not like ths.You have the reliablity of Linux,with Winders. riding on top of it for the Windows users. Sorry for long post.

I personally prefer /etc/hosts over centralized DNS for this, since it's really only used for LTSP client lookup purposes. The advantages to /etc/hosts in this case are as follows. 1.) You could have multiple 192.168.0.x and 192.168.1.x lookup tables (remember, everything's NAT'ed, and thus kept private). Yes, that means you can re-use this same /etc/hosts file on multiple LTSP servers without running into hostname/IP address conflicts across your network. LTSP servers already do this by default for 192.168.0.x. Sure, you could do the same thing with BIND running on each LTSP server, but it's a little bit more work to set up. Centralized DNS, to my knowledge, doesn't let you re-use hostname/address information at all (does it?). 2.) Say you do go w/ centralized DNS, since either you choose to use different subnets for each LTSP server's client segment, or you have only one LTSP server. If that centralized DNS for some reason does take a dump, the LTSP clients will have problems, but with either /etc/hosts or locally-running BIND present, they'll still be just peachy. They may not be able to hit Google or www.h4x0rz.com, but people can still get on and access their local files. --TP _______________________________ Do you GNU!?

While I agree that Jim is doing fantastic things and that supporting him however you can is a great idea $18 / eeprom is not cheap especially when you consider that it could be the single most expensive parts of some of the refurbished labs (excluding the server and network). I spent the money for a Eprom programmer and an Eraser so I am able to take advantage used EPROMs from ebay ($1 for used 27C256) as well as this site: http://www.futurlec.com/ICFLASH.shtml That being said, for the number of EPROMS I have programmed, buying them from Jim would have been the cheaper route. However, a number of Network cards can flash eeproms. The 3c905C is one of those cards and is readily available pretty cheap: http://www.vfxweb.com/index.php?productid=8006 I have purchased several from vfxweb and for some of them I got lucky and received cards with PXE built in. When it comes to remote booting I look for: 1) PXE support for the onboard NIC 2) PXE on the card (these are cheap whn you find them) Preprogrammed EEProms are for specific NICs (pci ids) and when you get into programming them yourself via a NIC you should have more time than money...

Try... man mdadm This will give you idea of how to manage the array. In such cases where one of the drive of RAID1 array goes bad just giving a command to remove drive from array and then adding it back and giving it time to re-build is sufficient. Unless the drive has physically gone bad there shoud not be a problem and after few minutes (depending on data size) the array will report ok. Note that you have to do this to each raid device ..md1,md2,md3..individually. Raid devices start numbering from 0 and hard disk partitions from 1 ...so typically md0 will have components hda1 and hdb1 The command, in sequence, that I have used are: mdadm /dev/md0 -r /dev/hdb1 mdadm -D /dev/md0 mdadm /dev/md0 -a /dev/hdb1 mdadm -D /dev/md0 Repeat fro all degraded arrays.Again read man pages and make sure you have backup.

Crossover linux? Openoffice.org? Message-ID: Goal: I am doing a fresh install for the new year. This time as well as setting up our children on K12ltsp I am trying to migrate our secretary. After the hard drive failed on her windows computer I thought it would be a good time to do it. The secretary needs MS Office, MS Publisher, MYOB (accounting package), ASB Fastnet Office. She also likes to listen to Realmedia lectures. She has been using realplayer to do this Approach: So we are trying Crossover Linux for the office apps. If I can't get the tricky apps (MYOB, Publisher) to install with Crossover Linux I will use Windows XP in VMware server. I am thinking of using mplayer and mplayer plugin for media. Realplayer would also be nice as that is what she is used to and I heard it is better than Mplayer at playing realmedia files. Also Flash 9 with sound. Results: Flash sound: I have already installed Flash 9 beta 2 using esd modification from Jean-Michel Dault at Revolution Linux inc. It's working great so far. MS Office under Crossover Linux: So far MS Office is OK (including MS Access) but I haven't figured our how to get the Crossover linux sound to the clients. When I add a sound to Powerpoint the sound works fine on the server when I use alsa driver. The esd driver makes sounds on the server but then freezes powerpoint. No sound at all on the clients. Openoffice I also tried OpenOffice.impress to compare the sound. No luck there. It seems you have to install a java applet to make it work. Don't know if if works with remote sound. I've heard that in Ubuntu there is a gstreamer version. That sounds more promising. Tuxmath, Tuxpaint, Gcompris have sound fine. So does Tuxtype2, and Childsplay although they are not listed in the gnome menu and when started they lead to "out of range" message on the monitor. xmms works when esound is set for remote host: host name. All the K... educational games etc. have no sound. blinKen complained that it couldn't open arts. I haven't installed Mplayer yet, but I know that it has native esd capability so there shouldn't be any problem. Also haven't tried VLC or totem with xine. Summary: Works: Flash in Firefox, Tuxtype2, Tuxpaint, Tuxmath, Gcompris, Childsplay, xmms, mplayer Doesn't work yet. K... programs, MS Powerpoint under Crossover Linux, Openoffice.org Impress Untested: Realplayer (v. 8 with esd) or (v. 10), VLC, Totem, Xine Hope this is useful for someone. Hopefully we can get more of the programs to run with sound too. Krsnendu dasa -------------- next part -------------- An HTML attachment was scrubbed...

If you need a quick fix: FC5 and newer use gnome-screensaver. In any case, a temporary fix is to launch fl_teachertool (as root of course) then select all users and click View. Now type gnome-screensaver into the input box and click Select. Now click Kill. Do the same for xscreensaver if that process exists.

Thanks, Nils. I think I found the cause, and a human was involved. When configuring /etc/dhcpd-k12ltsp.conf, I unwittingly gave the same IP address to two different MAC addresses.

Message-ID: <44418.192.168.254.3.1168806628.squirrel@www.eazylivin.net> Hi Scott, If this is fresh install of FC6,( or any version), I had this happen on one server many moons ago. Not sure why this cured it,but this was an AMD processor server. I bumped up the CPU timing from "default" to one speed higher and never had the Nautilus crash again. This went on for sometime, before I made the change so I'm sure the CPU timing change DID actually cure it. I m guessing if you had faulty memory ,the results could be the same. I know you'd think if this worked OK for previous version K12LTSP ,it should work Ok for the latest.greatest version of K12LTSP. If this server is an AMD ,I'd give this a try ,wont hurt anything. A simple reboot, dive into the bios and adjust CPU timing up/down one speed. Mine was on a fairly old AMD processor server ,FYI. But works like a charm for its purpose. Naulitlus would crash at the console as well as on clients too,just so you know. Let us know what you figure out.

Otherwise anyone who has root on their own machine can mount any nfs share and automagically have root on it as well. You'll probably need to export this directory with the *no_root_squash *option. Here's a little blurb on NFS that might help.

So would plain text. The raid is not being rebuilt alongwith others since it is likely to be de-graded. When you run delete component and then add component you can see the raid array being re-built by "mdadm -D /dev/md2" Just run it couple of times after interval of a minute or so and you can see the progress of array re-building going on. If it still gives errors then you need to dig in further to find out what is causing it. -- Regards, Sudev Barar -------------- next part -------------- An HTML attachment was scrubbed...

I think I forgot to mention in my prior post that ping works fine from the Windows clients as long as I specify an IP address; when I ping using a name, ping fails. I get similar results with web browsers... going to a site by IP address works fine, but doing so by name (www.whatever.com) fails every time. Which tells me I have a name resolution problem. I noticed that there's at least one other person in this discussion thread seeming to have the same problem as I'm having. For me, the crazy part is that my other k12LTSP servers work fine as far as this goes. But when comparing settings between them, I do not see any differences. Most likely, though, I'm looking in the wrong places. Any suggestions on what I should check? thanks!

I think I edited the following files: /etc/sysconfig/networking/devices/ifcfg-eth0 /etc/sysconfig/networking/devices/ifcfg-eth1 changing the hardware addresses in each file to match the MAC of the physical cards. (I got the idea from a discussion thread from about a year ago.) As a disclaimer: I said "I think" that's what I did because a) I don't have my setup notes for that server with me at the moment, and b) won't be able to check the server itself until this evening. I'll send a follow-up if it turns out I actually did something different.

At least, when trying to install, the raid card is not recognized. I tried booting using linux noprobe and then manually specifying the dpt_i2o device, but ... two screens later(when you are asked about the installation/partition option) no drives are found during the installation. I also tried just typing yum upgrade, and since this system is currently at FC4 (running very well, but have to upgrade it for other reasons), it does not run an upgrade to the latest version of k12ltsp. So ... other than removing the i2o card and using either software or no raid, what are my options? Is there a command line option during the install process other than noprobe that might ensure the raid card is detected? Finally, on a different note: Comcast is currently blocking all email from k12osn at redhat.com because according to them the mail server cannot be verified. Eric or Paul, if you need more information, please email me at either this new email address or at my old one (dahopkins_at_comcast.net).

I have installed k12LTSP. I have successfully setup authentication to our Win2k3 server. I have also setup automount home dirs to /home/DOMAIN/user. however, some students have problems writing files to their windows share. it appears that on the windows side, everything is fine, the owner of created files is correct. But when creating files on the thin client, it does create them, but it shows the permissions wrong. it show the owner as root group as root. when this happens, a student cannot save to that file becuase it sees the owner as root. however, the student can delete the file. Like I said, windows show the permissions correctly. I do have some students that do not have the problem. it shows the owner as them in natilus and group as domain users. the can write to files just fine. i cannot seem to see any difference on the win2k3 server between these student. any ideas?

Next time you do an K12LTSP6 install select the Mail Server section and make sure all packages are checked. This will install all packages you need to run a mail server & simplyfy things for you next time. You will need : 1. sendmail( which is installed) 2. dovecot 3. procmail ( if you want to setup spamassassin) 4. spamassassin ( if you want spam killing) 5. Squirrelmail 6. Apache FYI:All of these packages/rpms are on your k12ltsp6 cd's. Note: you really dont need procmail or spamassassin if you are going to run an "internal"/intranet only mail server. yum install all of these. now you are set go into the System>Administration>Server Settings > Services and make sure all of these are started,as well as checked to start at boot> Save. Once you have all of these running,point your webbrowser to http://localhost/webmail You will get the Squirrelmail login. Whoever has a user account on this server will be able to log in right now! By deafult sendmail is setup to send on localhost only, which is what you are wanting( I think), to only send emails internally/ not via internet. If you are only wanting for students to send internally you are up and running! If you want to send externally you will need to setup mx records etc in your BIND config,which can be kinda daunting until you have it working. Post back if you run into any snags. Let us know your progress.

The dhcp clients should be getting the k12ltsp server's address as the DNS server as well as the default gateway. You should see this with the ipconfig /all. The server itself will do its own lookups (and thus those for thin clients) based on the 'nameserver' entries in its /etc/resolv.conf file and the local /etc/hosts file can override those lookups. However, to act as a nameserver for other machines, you must have the named program running and configured properly. Some tests you can do: service named restart If you don't see the 'OK' during the shutdown step, it wasn't running and you need to 'chkconfig named on'. If there are errors in the startup you need to fix /etc/named.conf file. dig will show the root servers based on lookups from a server in /etc/resolv.conf. If this works but dig @localhost does not work, your nameserver can't reach the root servers. One thing that might cause that is firewalling at your internet gateway. You may have to add the nameservers listed in your /etc/resolv.conf (which seem to be working) and add them as 'forwarders' in your /etc/named.conf file. This will make your named pass the queries to the specified (and reachable) servers instead of attempting the lookups directly. Once you have named working on the server, the clients behind it should also work, which you can test with 'nslookup some_internet_name'. -- Les Mikesell les at futuresource.com From brcisna at eazylivin.net Mon Jan 15 17:47:16 2007 From: brcisna at eazylivin.net (Barry Cisna) Date: Mon, 15 Jan 2007 11:47:16 -0600 (CST) Subject: [K12OSN] Student run mail system Message-ID: <55586.192.168.254.3.1168883236.squirrel@www.eazylivin.net> Hi Nils, Thanks for the pointer on the "yum groupinstall"..

Message-ID: <1168881375.20075.7.camel@penguin.anderson.local> Hello, I am running K12LTSP 5.0 at a computer lab I set up as a volunteer. I am doing administration and teaching there once a week. When the lab was set up it was set up without sound. This included not installing the audio applications. I have since set up lts.conf for the terminals' sound. I get an error that it cannot located /dev/dsp. I think this is because the sound packages are needed. How do I install the sound packages now. I've tried the yum based tools but have not been successful. I have also received errors that the K12LTSP repos are not available.

In-Reply-To: References: Message-ID: <45ABCCA6.8070402@cmosnetworks.com> First, it's not a good idea to attach Microsoft .doc files, since not everyone here uses MS Windows or MS Office. Furthermore, .doc files very often contain macro viruses and even embedded CraptiveX controls. I never open those from untrusted sources. Much better to use .odt or .sxw, since we all here do use K12LTSP. Now, to your question. Sure, if you want Internet connectivity, it'd be easy to add a third NIC. However, a much safer option is to have some kind of packet-filtering router between your K12LTSP server and the Internet. This way, your Windows clients could also hit the Internet. I'm assuming here, since you say that you cannot connect to the school's network, that you have a second Internet connection, e. g. broadband or separate T1 line. Also, doing it this way (packet filter in front of the Internet connection) saves you from having to bother with a third NIC in the LTSP server. Am I understanding your situation right? --TP _______________________________ Do you GNU!? Microsoft Free since 2003 --the ultimate antivirus protection!

Sometimes, Ive found ,I overexplain instructions. The instructions,in the link I provided did not give the "devel" packages that are needed for pusle & esound audio,and for Make to compile the libflashsupport.c file to compile correctly. Good call !:) The bottom line Flash Player 9 WILL work, with sound on terminals. The same instructions you posted here, will work on K12LTSP5 as well. Just so everyone knows. Glad the " touch /tmp/.esd/socket " routine revived your flash sound. Do the cron job script as you mentioned ( on the ltsp wiki),to keep the socket "there" to cut down on having to manually recreate it!

If not please let me know. I have put together a tar.gz of what works on two of our k12ltsp v5 servers to get sound through Flash Player9 -plugin. This is a "manual" install. Please know that this has ONLY been tested on k12ltsp v 5 32-bit. It may or may not work on older/newer vesrions of k12ltsp? I know a lot of people here have put a lot of work into getting things to work in the k12ltsp . Credit goes to Jean-Michel Dault at RevolutionLinux, for the code in the libflashsupport in getting both esd and pulse audio to work along with FP9-plugin on terminals. I have only assembled the files after i compiled them on k12ltsp v5. the file is : flashplayer9-esdpulse-k12ltsp.tar.gz (about 2.5 mb's) If you feel brave go here to download from my humble ftp site and read the install.txt inside the tar.gz to get it all installed: ftp://eazylivin.net/pub/flashplayer9-esdpulse-k12ltsp As a precautionary measure i have also upped the flash-plugin7 rpm as a backup. If you would like to revert back to FP7.It can be found here: ftp://eazylivin.net/pub/flash-plugin7-rpm Please post positive/ negitive comments on how things went. Hope this is alright with everyone and hoping it may help .

I think that we are the only ones to use it State wide. We replicate the data to the State level. The IT staff at the State can see our data at any given time. I just returned from the STI user's conference. All they kept talking about is their new web based application called Information Now. After supporting the old POC, piece of crap, for the last 8 years, I am doubtful that they are capable of producing anything worth while. During the conference I asked a couple of questions about the new software: 1.) Does the web server have to be IIS? Yes, STI is soooooo Microsoft centric that it is disgusting. 2.)

Google, Yahoo and a whole bunch of other large companies are doing massive development around AJAX. I'd say it's widely used now, and will become even more so. I dislike Microsoft just as much as anybody on this list, but I really do like AJAX. I'm doing some incredibly cool cross-platform GUI programming using AJAX and it would have been far more difficult (damned near impossible) without AJAX.

Not sure I would bet the farm that it will become > widely used in the long term. There are some pretty obviously good uses for Ajax (Asynchronous Javascript and XML, formerly known as DTML...) in a student information system, because using Ajax in a complex form like a gradebook spreadsheet data can be sent to the server as each form element is entered, rather than only when the whole form is submitted. This gets around classic problems like accidentally closing the browser window after spending an hour entering 3/4 of your grades or having your session timeout before you submit the grades and losing them. Of course, Ajax isn't the only way to prevent these, and, like anything else, it can be done badly. --Tom From microman at cmosnetworks.com Tue Jan 16 04:56:45 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Mon, 15 Jan 2007 23:56:45 -0500 Subject: [K12OSN] Web based Student Information Systems?

Same with FAT; it's a technique of organizing files on a storage device. Are we sure that this AJAX won't come back to bite us in a legal sense? I ask this because Jim McQuillan just said that it was indeed written by Microsoft, first as "XMLHTTP". I quote Mr. McQuillan: "Actually, AJAX should be considered a Microsoft thing.

(Even Microsoft can > have a few good ideas)" Jim's explanation there is a bit of an oversimplification. Here Jesse James Garrett in the 2005 essay which created the term Ajax (note he does not work for Microsoft): http://adaptivepath.com/publications/essays/archives/000385.php "Ajax isn't a technology. It's really several technologies, each flourishing in its own right, coming together in powerful new ways. Ajax incorporates: * standards-based presentation using XHTML and CSS; * dynamic display and interaction using the Document Object Model; * data interchange and manipulation using XML and XSLT; * asynchronous data retrieval using XMLHttpRequest; * and JavaScript binding everything together." All those pieces were prexisting technologies with multiple implementations and at least draft specifications by an open standards body. Microsoft gets credit for coming up with the XMLHttpRequest API originally (and supporting XML in general) but that's about it. Also, if you look at the examples in Garrett's essay, none of them are from Microsoft. > Hence, the concern.

If F/OSS developers start trying to verify that they are infringing no patents before they write software, they won't be able to write any software at all, the whole software patent is just a complete mess. --Tom From thewhitmers at gmail.com Tue Jan 16 12:43:19 2007 From: thewhitmers at gmail.com (David Whitmer) Date: Tue, 16 Jan 2007 07:43:19 -0500 Subject: [K12OSN] Blocked net access In-Reply-To: <45ABBC89.2040909@futuresource.com> References: <72E8F49B-A217-11DB-ABB4-000393C5DC16@k12.hi.us> <45A78F68.7060002@futuresource.com> <45A79CB1.4040503@maltzen.net> <45A7BF12.3060009@futuresource.com> <45A7C6CE.1000403@mail.mesd.k12.or.us> <45ABBC89.2040909@futuresource.com> Message-ID: On 1/15/07, Les Mikesell wrote: > > The dhcp clients should be getting the k12ltsp server's address > as the DNS server as well as the default gateway.

As I was getting ready to add "forwarders" to /etc/named-k12ltsp.conf (there doesn't seem to be a named.conf) I noticed the following option commented out under options: /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below. Previous versions of BIND always asked * questions using port 53, but BIND 8.1 uses an unprivileged * port by default. */ // query-source address * port 53; I uncommented the query-source-address, restarted named, and like magic name lookups from the Windows client, whether using ping or a web browser, began working. Though it seems I may actually have been having a firewall issue, I nonetheless learned a lot about working with name servers. Thanks for your help everyone!

But there may be more. The AOpen uses a Realtek chip, some derivative of the 8139, I'm pretty sure, while the Intel probably uses something made by Intel. Realtek chips show up on most of the cheap cards, and even some of the more expensive ones; I've noticed the latest Linksys wireless cards use Realtek chips inside. In my experience, Realtek chips have always worked well with LTSP, and I use them frequently in clients. I'm even using some gigabit cards in servers that use a chip made by Realtek (different model, I forget the number), although I haven't benchmarked their throughput. And I think Realtek is considered one of the better companies about working with Linux ethernet driver developers, in that they don't hide stuff in proprietary, binary drivers with no published specs, like other companies tend to do, e.g., Marvel. However, I have also read, although I don't know if this is accurate or not, that part of the reason that Realtek chips, and the cards they appear on, are so inexpensive is that they push more of the processing of the networking back onto the system's CPU. In other words, I have seen them derisively referred to as the 'winmodem' of network cards. Again, I don't know if this is accurate, or just snobbery or posing by sophomores who don't actually know what they're talking about. In the client, it probably doesn't matter, and the cheap cards are just fine. But in the server, depending on the number of clients being supported, the apps involved, and the available resources of the CPU--is it a dual CPU, dual-core, single-core, how fast, etc.--it MAY make sense to spend $40 more for a 3Com or Intel GB NIC. Or it may not matter, the criticisms of Realtek chips may be just propaganda from friends of Intel & 3Com, and that extra $40 may be wasted. I'm not certain. I'd be curious as to anyone else's opinion.

I'm not certain. I'd be curious as to anyone else's opinion. I prefer Intel NICs, FWIW. That's not some generic Intel prejudice on my part - all my home systems (and most which I assemble for others) use Athlon 64s. The Linux server companies I'm familiar with (Penguin, ABMX) also seem to concur on Intel NICs.

Opterons have generally had better performance than Xeons, which is one of the main reasons AMD has had such good sales numbers for the past few years. Now, a 2-way quad-core Xeon box might outperform the Opteron box, since it has more cores available. But all of this is predicated on your app being able to take advantage of having that many CPU cores. And it depends on what the app does. We have some perl scripts that parse huge XML files and load them into Oracle. We moved them from a HP Itanium box (eight CPUs? Can't recall exactly) to a handful of Opteron boxes because the parsing turned out to be CPU bound, and the Opterons could run rings around the HP box. But as far as hosting the DB, it stays on the HP because it handles the IO better. (We'd look at using clusters for the Oracle DBs, but we're being absorbed into another company, and it won't be our problem shortly).

Opterons have generally had better performance than Xeons, which is Amen - especially due to NUMA and AMD's Hypertransport. In the benchmarks I've seen, it seems Intel CPUs beat AMDs on closed-source benchmarks (which may be using code optimized for Intel), while the opposite appears to be true with open-source benchmarks (not playing CPU favorites). So I'd suggest buying the Opteron systems, and maybe spending part of the difference on more RAM (unless if the server is already maxed out).

Whether this is to your advantage or not depends on how much you're willing to spend on a lawyer ;P I'm certainly no expert on CIPA, but as I understand you have to use your best efforts to block or filter and visual depictions that are "harmful to minors." This includes pornography, of course, among other things. So if you offer an unfiltered email system to your students and they are all well behaved individuals, then I doubt you will ever have any problems with CIPA or receiving E-rate funding (if that's why you ask). However, if the students learn that they can email pornographic pictures to their school hosted email address and view it on district owned and maintained PCs, then you may start running into some problems. There are some vendors out there that offer email account specifically designed for the K-12 niche which allegedly scan image files for potential pornographic content, etc. The only one that I can think of off the top of my head is Gaggle.net. -Abe ________________________________ From: k12osn-bounces at redhat.com [mailto:k12osn-bounces at redhat.com] On Behalf Of Jason Neiffer Sent: Tuesday, January 16, 2007 2:06 PM To: Support list for open source software in schools.

This is as good a place as any to ask the question. Having managed the development of a GPL-ed SIS for the past couple years, I've got some experience with the matter. A student information system for one school, or for one type of school isn't a very complicated operation. I know of plenty of anecdotal cases of a team of two or three reasonably competent developers writing a system for their school in a year or less. In the past, this usually meant FileMaker or FoxPro, but agile frameworks like Django or Rails provide equally rapid development. I'm not sure what the difference in cost to scale up to a whole district would be. The Providence School Department still runs off a FoxPro database, as far as I know. I think it is fair to say that the knee-jerk reaction by most folks is to jump up to a big Java solution, but it is probably not necessary. Anyhow, the big question becomes your ambitions beyond simply making an application for your district. I've found that the numbers in the first chapter of the classic Mythical Man-Month are pretty accurate. That is, if just writing the application for your own use takes X amount of time. Getting it to the point where it is sufficiently robust, documented, packaged, tested so that anyone can use it will take 3X. If you want it to be easily modified and extensible in a systematic way by third parties, that'll take 3X. If you want both, you're looking at 9X. This is, generally speaking, why there are so few open source SIS's, despite the fact that a number of people have written systems for their own schools using open source frameworks. The one or two developers who wrote the application can't then devote the necessary time to turn it into an ongoing open source project. Regarding a choice of frameworks... I do think the first question is PHP or not PHP. Among people actually working in schools, and thus who are more likely to understand the requirements of the application well, PHP seems to be far and away the most commonly known and used language. Also, Moodle, Drupal, MediaWiki and other similar, popular apps are written in PHP. And it is supported by just about every web host, etc. On the other hand, it is probably the option most likely to cause you security issues, if not because of the inherent properties of the language, because lots of those PHP programmers know exactly enough to be dangerous, and the language itself makes no effort to keep them from hanging themselves. I'm generally a not-PHP person. Whether or not you'd use Java pretty much depends on if you have Java programmers handy and money to pay them. Just using Web2School (written in Java) will become an option if Wicked Good software open sources it. They've stated their intention to do so, but they may find it is a longer, more complicated process than it appears to be. They seem like nice guys, but I'll believe it when I see it. Rails, Django, etc., seem like good options. The weird thing about designing an SIS based on one of these is how do you handle customization? Not that they are difficult to customize; they're easy to customize. In fact, it is so easy to customize them, it isn't clear exactly what a general purpose Rails or Django SIS is. For example, if I had a Rails SIS, and I needed to modify the demographic form for our students, would I do it the Rails way, and modify the tables and run generate scripts? Or would I modify the form through some administrative screens in the web interface like a normal SIS? If the answer is the latter, we've immediately ditched some of the basic assumptions that make Rails development so fast and efficient. As you may know, SchoolTool is written in Python using Zope 3, which on its technical merits is extremely well suited to the task. The problem is that Zope 3 is not very well known and has a somewhat idiosyncratic design, so it is hard to find developers, particularly in the US. Although... now that I think about it, Vancouver is actually a hotbed of Zope development, and I even know some Zope 3 developers there. So building on SchoolTool would actually be a possibility for you.

I'm using an SME server (based on CentOS) running DansGuardian for content filtering/proxing...etc. I'm also running proxy auth. So the way it works now....if the user has the proxy server (10.0.0.1 port 8080) set in their browser, then they get challenged to log in the moment they try to open a browser. They log in and then surf from there....and are filtered according to the group that they are a member of (in other words students are filtered more harshly than staff....etc). If the browser does not have the proxy set, then they are transparently proxied and are filtered at the default level (which is pretty harsh in our case to encourage logging in). Now my dilemma. I still need to play with this more, but at the moment if I enter a different proxy, such as 195.179.62.1 or something like that I may have found on the Internet, I can essentially bypass the filter. What I want to do is to find a way to ONLY accept either no proxy setting (thus transparent) or 10.0.0.1 on port 8080....and nothing else. If a kid enters any other proxy in their browser....it simply doesn't go or gets dropped. Any ideas? I'm not desperate here as I'm in a middle school and the kids know that I know more than they do and can monitor most of what they do, I'm just thinking ahead and trying to solve somthing before it becomes an issue. Anonymizers and proxyfiers are causing major issues in other schools and I want to help them out. I'm open to all sorts of ideas.....even other firewall/content filters like IPCop and the like (FOSS only please) ;-) Can you help? David N.

Interesting to see which will thrive. I think you may be focusing a bit too much on the programming languages used. Probably any language out there can be used to create a great SIS, but you just need a bunch of good developers. If you have a bunch of good developers that prefer to use language X I wouldn't try to force language Y on them, just because Y was used to develop that one fantastic system Z.

Any ideas? > I think this would require a pretty tight firewall policy that would prevent using "outside" proxies. Blocking (outgoing) TCP ports 8080 and 3128 would go a long way toward preventing attachment to proxies beyond your perimeter firewall. An even tighter policy (essentially blocking most outgoing traffic) might be required to completely prevent such access.

Take a look at the common proxy servers that are freely available and can be set up easily by students at home. Then create rules to filter (for example, proxy.php). http.dnsbl.sorbs.net List of Open HTTP Proxy Servers. socks.dnsbl.sorbs.net List of Open SOCKS Proxy Servers. misc.dnsbl.sorbs.net List of open Proxy Servers not listed in the SOCKS or HTTP lists. (many others exist, these were just easy to access) In my area, the town library makes a number of online databases available over the net that we don't /can't afford to buy ourselves. Unfortunatly you must use the libraries proxy server to access it. My point is that while you are doing this, you should also create a list of approved (white listed) proxy servers that your students or staff may need to access. ---------------------------------------------------------------------- Steven Santos Director, Simply Circus, Inc.

I simply went into the firefox browser .js file and hard coded the proxy settings sytem wide. Edit: /usr/lib/firefox-x.x.x.x/greprefs/all.js drill down to line 618 change the proxy line & port line #'s to link to your border router/firewall.. There is a way to make this "grayed out"/ unchangeable as well , but I never went to the trouble of doing this,but you'd want to do this Im sure as much trouble as you've gone to to make this happen for your school. If the kids know how to find this setting in the browser they can "delete it" for their given login session. next time they log in,it is in again though.

Whether this is to your advantage or not depends on how much you're willing to spend on a lawyer ;P I'm certainly no expert on CIPA, but as I understand you have to use your best efforts to block or filter and visual depictions that are "harmful to minors." This includes pornography, of course, among other things. So if you offer an unfiltered email system to your students and they are all well behaved individuals, then I doubt you will ever have any problems with CIPA or receiving E-rate funding (if that's why you ask). However, if the students learn that they can email pornographic pictures to their school hosted email address and view it on district owned and maintained PCs, then you may start running into some problems. There are some vendors out there that offer email account specifically designed for the K-12 niche which allegedly scan image files for potential pornographic content, etc. The only one that I can think of off the top of my head is Gaggle.net. -Abe ------------------------------------------------------------------------------ From: k12osn-bounces at redhat.com [mailto:k12osn-bounces at redhat.com] On Behalf Of Jason Neiffer Sent: Tuesday, January 16, 2007 2:06 PM To: Support list for open source software in schools.

I'm not sure if this is exactly what is needed, but suspect it could fit the bill. Block Out Traffic BlockOutTraffic (in short BOT) is an addon for IPCop v1.4.x. BOT will block all traffic that is allowed in a normal IPCop installation. For example Green -> Red is blocked after installation of BOT. Rules must be created to allow traffic, which means (hard) work but allows for more influence on traffic to and through your firewall. BOT Rules are created by using a very intuitive extension to the IPCop WebGUI. The URL is http://blockouttraffic.de/index.php I'm pretty sure this issue has been discussed on the IPCop mail-list. There are a heap of good addons for IPCop at this website http://firewalladdons.sourceforge.net/ Even though IPCop says it is targeted at the home user, small business, I know it is being used on some LARGE sites.

He didn't say the users were stupid, he said they were ignorant. That simply means that they don't know or understand something, which is true in this case. It doesn't convey superiority, or at least it shouldn't. Tone is hard to convey in an email, but I wouldn't necessarily assume that he was blaming the users. He just said that they would require some training. Frankly, that's a good idea with any new application. It will simply be one more thing to cover in the training. The back button is designed to take you back to the previous URL you visited. It doesn't say undo on it, nor does it function that way. Many web forms warn you that hitting the back button won't unto hitting submit, so this is hardly a unique problem to AJAX sites. Since a webpage shouldn't be able to alter the browser controls (that would be a huge security hole), we are going to have to train/educate users on that idea as part of using a new web-based application.

Well, a web page CAN intercept the "going away" events, and decide to 1) save the data, or 2) warn the user, and cancel the event. (Zimbra does this) OTOH, there is some way to save state information, since Google Mail does it. OTGH, Google's programmers are probably smarter than average (including me), so it may take a lot of effort to do so.

Security updates for such an old version are no longer forthcoming. That version was based on Fedora Core 1, and you're putting your system and users at some risk by not upgrading to something with security updates. The Fedora Legacy project, which supported even Red Hat Linux 7.3, has closed its doors. It's a similar situation to using, say, Windows NT Server 3.51 or 4.0. If you'd like to stay with a single version of K12LTSP for a long period, you might consider the "Enterprise" version of K12LTSP, which is based on CentOS. Security updates for CentOS will be available until the year 2012. Now, that said, one approach would be to download the latest Firefox from www.firefox.com and install it manually. I tend to use /usr/local/firefox for this. You'll have to point your existing symlinks (/usr/bin/firefox, usually) to this new install of Firefox. If /usr/bin/firefox isn't a symlink, but rather an actual file, then just rename /usr/bin/firefox to, say, /usr/bin/firefox.orig. Then symlink (in this example) /usr/local/firefox/firefox to /usr/bin/firefox, and barring any other FC1-specific idiosyncracies, you should be in business with the new Firefox version. But you really, REALLY should upgrade your K12LTSP installation to something current. That's the proper fix. --TP _______________________________ Do you GNU!?

I have fixed that. :-) Now, to your question. I find Edubuntu to be a bit lacking in the LTSP department, and that's been true since Dapper Drake. You can get it to work, but I've found that either you have to take the defaults exactly (and know a little of what you're doing), or you can not take the defaults and *really* have to know what you're doing. I have been using Yellow Dog Linux successfully as a server OS on various types of PPC machines, including a Power Mac G3 B&W and a Total Impact briQ. As a LTSP server, I've run both Y. D. L. and Kubuntu on my PMac G4, and both work just fine. With both Yellow Dog Linux and Kubuntu, I installed LTSP myself from www.ltsp.org. In fairness to Edubuntu, though, if you're trying to use Feisty Fawn, then please remember that Feisty is still pre-release! If you're set on Edubuntu, you're much better off trying either Dapper Drake or Edgy Eft. Like I said, I find it a bit lacking, but it does actually work. --TP _______________________________ Do you GNU!? Microsoft Free since 2003 --the ultimate antivirus protection!

While Hardware RAID controllers will give you a better performance their price is very high. I would recommend using the OS RAID, its robust and I have even tested it by simulating a powerfailure while the drives were actively working. The OS RAID staid intact and no data was lost (ext3 file system). Once your system is up and running use the following command to test your drive speed #hdparm -Tt /dev/md0 Timing buffered disk reads: 132 MB in 3.03 seconds = 43.54 MB/sec Is what I get with a VIA onboard SATA controller.

There's usually a utility, accessible at bootup, in which you specify which drives are to be RAIDed, and what level of RAID to use (striping, mirroring, etc.) and the controller does all the setup for you. Hardware RAID may also have better caching on the controller. The advantage of software RAID is that it doesn't take any special hardware or cost any additional money. Plus, with software RAID, you can take a disk from a RAID system and put it into any other system--you aren't tied to the RAID controller. In most cases, you cannot switch RAID controllers--different types, that is, not identical--and have the RAID still work. IOW, hardware RAID works and works well, but then you're tied to that hardware. I use both, largely depending on budget and need, e.g., how expensive is downtime?

Earlier versions of Fedora have multiple kernels, be sure to use the SMP kernel. FC6 sometimes has problems correctly identifying the kernel architechture, so make sure you get the right kernel upon installation. My laptop's Core Duo (aka Centrino Duo) was mis-identified as an i586 so I had to rectify the problem myself (you may not have the problem on the Core 2 Duo, which has a different lineage than mine). You won't have to "tweak" anything to get load balancing between cores and there is no provision for changing the default CPU behavior in the way that you suggest.

He said that as pluggable devices become more common, such as USB disks and sticks, it cannot always be guaranteed that /dev/sdb3 will be the third partition on the second SCSI disk. With the advent of SATA drives, which appear as /dev/sd* devices, one can foresee a day when all storage is a /dev/sd* device. With labels, which are written to the device, hot plugging and unplugging of devices won't interfere with the OS disks. All of which makes sense to me, so I've been trying to get in the habit of using labels.

In-Reply-To: Message-ID: Plan for upgrades is perhaps the best advice. Some simple things done during construction will make life a lot easier in the future. Home-running low-voltage conduate from your network patch room to each and every other room in the building is a good thing. Depending on the building layout, you may need more than one patch closet (and a conduate directly from each patch closet, to each patch closet AND to your server room). Follow a standard methodology when you do this. Make the conduate a size larger than you think you will need. Think about how to make use of non-traditional spaces for LTSP. Where might you be able to station 4 or 5 workstations as mini labs or so people can check email? Where might you need to plug in a rolling cart of workstations? Hallways, entry ways, etc. Think about spaces that would otherwise go unused in the building. Make sure you have power at each network drop. I personaly like to use combo boxes (wall boxes with closed high voltage spaces, as well as open low voltage spaces) everywhere I would put a network jack. Think about using cat7, or at least cat 6. Also, use solid core wires for the in-wall runs, especially longer runs. Obviously, run eathernet where ever you would otherwise run phone cable. Don't forget about coax. Drops to each room, homerun to your patch closets. Also, plan for wi-fi coverage both indoors and out. Parking lots are often overlooked, but very useful to waiting parents. ---------------------------------------------------------------------- Steven Santos Director, Simply Circus, Inc.

That's an ajax-based navigation, and it's a bad use of the technology. There are plenty of useful things you can do with ajax that can enhance a web site. For example, a quick database-backed lookup for a form textfield. That can potentially make the user experience better when filling out a form without the need to dump a large amount of data into a select box or javascript array, or forcing a popup window. Further, the dynamically generated XML response doesn't need to be overly verbose, and can likely be a much smaller amount of data to transfer. Sorry to beat a dead horse, but I was just disagreeing with the widely held misconception of an inherent back-button problem for all things ajax. Ajax doesn't break the back-button, bad programming breaks the back-button.

In-Reply-To: References: Message-ID: <45B07FF8.1070808@cmosnetworks.com> I would have multi-mode fiber-optic cabling between all of your wiring closets, no exceptions. This is for several reasons. The first is that, going forward, you can easily use Ten Gigabit Ethernet in, say, ten years from today. No, don't laugh; my district used to think, not so long ago, that Cat 3 cabling "was good enough." Well, ten years later, we just got through spending boatloads to rip out all that Cat 3 and put in Cat 5e. Had we put in Cat 5 in the first place, we would not have had to do all this and spend all that money a second time. Oops.... The second reason to use fiber between the closets is so that you're immune to the fluorescent lights that are likely going to be in the building. That, and fiber will let you go considerably longer distances. There are two grades of multi-mode fiber, 62.5um and 50um. If possible, go for the 50um, but if you can't do that, 62.5um will certainly do the job. I've got both types in my house, and they both work fine. The third reason to use fiber is the LTSP server itself. Remember, a single session of TuxType can suck up 73Mb/sec. That means that you can have 14 kids simultaneously playing TuxType before you fill up the Gig-E link and start seeing degradation. In the future, Ten Gig-E will come down in price. With such a NIC, you'd be able to have the entire computer lab of 30 kids playing TuxType or TuxMath at once, and your server's NIC will not be a bottleneck. Yes, that means a fiber Ten-Gigabit NIC. No, that won't be cheap. But, in time, it'll be a heck of a lot cheaper than a second server. Remember, you're looking ahead here, not just to tomorrow. All of this means, use fiber, and furthermore, use fiber bundles of maybe four to six pairs each. No, not four to six *strands*. I mean four to six *pairs*. Your school will thank you big-time in ten years. For your workstation links, I'd suggest going with at least Cat 5e, and if you can do Cat 6 without spending a boatload more money, you might as well do so. As far as the number of drops in each classroom, my district has learned the hard way to err on the side of excess. We have learned not to consider it unreasonable to put twenty (yes, 20) Cat 5e Ethernet drops in each and every classroom, spread around on all four walls, and any computer labs of course get many more drops. Yup, that means lots of patch panels. Don't make the mistake we originally made and skimp on the number of drops. Note that, since you're using Cat 5e, each of those links would support Gigabit Ethernet to the desktop, as the IEEE 802.3ab spec for Gig-E across copper actually calls for Cat 5, so Cat 5e obviously would be just dandy.

Unfortunately, I appear to be firmly in the 'not for others' camp most days. Now, this issue has come to a head here at NCS. I have been told to either get sound working by February 16th (flash, movies in various formats like real player, media player,etc) or else NCS will find a different approach. In other words, a MS-based solution. What is pushing this is that teachers have decided (and management has agreed) that the school should be using UnitedStreaming and a contract has been signed. Now, I have to have sound. So, I have a couple of weekends to try and get this fixed. I am at FC5. I can upgrade to FC6 is absolutely necessary, but even then there are issues with the installer recognizing my RAID card (2010s). Currently, I have sound with the edutainment apps. It can be a little laggy at times, but ... it works. I am re-installing mplayer, hoping that doing so will get the movies working (using info from the list and the wiki). And that leaves flash and shockwave. Shockwave is a non-starter (well, maybe with wine, but ... purchasing codeweavers might work, but is cost-prohibitive since doing so gets into the same price range as an MS-based solution). As recent email to the list suggests, flash 9 is also having problems. So ... if anyone has success stories and are willing to take the time to add them to the wiki, I suspect alot of others on the list (besides just me) would find it very useful. Next, my version of LTSP still has the 'only works for first user' issue. An upgrade is in order. Is there a simple way to upgrade just LTSP without breaking the customizations which K12LTSP uses (and which make life alot simpler in many respects)? Finally, pulseaudio, asla, esd, nasd, gstreamer etc have been mentioned as possible solutions to the 'sound issue', but currently it appears that there isn't a firm solution. I have been trying to get a solid solution for literally a few years now. I have had sound working at varous times, but then it would lag so severely in videos as to be useless.

If you're using various old desktop PCs, the challenges of sound are amplified (no pun intended) by the various sound cards that are typically found in old PCs. I like using old PCs as clients because they're cheap--free, that is--but from a management standpoint, buying dedicated thin clients for $150, in which sound tends to work out of the box, may make a lot of sense. I'm pretty sure UnitedStreaming video should be doable. I seem to recall that William Fragakis and Daniel Howard in Atlanta said they were using it with their thin clients. Perhaps they can chime in on what app they use for it. If the school decides to go to an MS solution, I'd suggest building a separate lab for that special, very expensive circumstance. And not to put too fine a point on it, but which teacher is going to take the pay cut to pay for that MS solution? (snooty rhetorical question).

And I get the impression, Dave, that you're the sole computer support volunteer/tech/person. So, the MS solution will work to begin with, but then will slowly degrade as each system slowly (or quickly) gets out of whack from the kids noodling around with them. And where will the additional time to maintain, fix, and re-fix these machines come from? I'm trying to not sound snooty here, but make sure your school knows that a lab of 10 Windows boxes is TEN TIMES THE WORK of a K12LTSP server with ten thin clients. Which means the MS lab is only 10% as reliable as the K12LTSP setup. Petre Petre Scheie wrote: > What are you using for clients?

I'm also pretty certain all people that don't have working sound have non-working sound because they used things like ESD and OSS and now the flash-plugin only works with ALSA. ALSA is a superior solution, but I imagine that some things need to be changed before it works on a system that didn't use ALSA before. Alas, I don't have a K12LTSP server at the moment so I can't really try out anything. Nils Breunese. -------------- next part -------------- A non-text attachment was scrubbed...

In-Reply-To: References: Message-ID: Howdy, I second the motions for a minimum of solid Cat6 for the in wall runs. Also, If you're wiring a single building, you should probably try to have all of the cables terminated in a single closet so that you can avoid having to install any fiber runs between intermediary closets. You will save money on hardware (no fiber and/or SFPs/GBICs necessary) and it will make administration of the network much easier (a single managed switch versus multiple). For classrooms, I prefer to have my network drops and power boxes distributed evenly throughout the room, usually with 4 RJ-45s per box and 2 5-15 sockets per box. You can never anticipate how one teacher may want the room setup and you can never guarantee that the same teacher will occupy the same classroom forever. I feel better asking "where would you like these computers to go?" rather than stating "you have to buy a new table so that we can hook them all up over there in that dark corner." And from my experience with construction companies and E-rate (if applicable in this case), be very specific with the wiring standards. Don't say "this many drops per room." Say, "I want category 6 cable that meets these specifications, manufactured by one of these companies, with exactly this number of drops in exactly these locations." Otherwise, who knows what you might receive. :P As for the banquet halls and community areas, you may want to consider using wireless in those locations and also have some floor drops installed with Ethernet and power. I would suggest that you at least have power in the floor if you go the wireless route so that you won't have to have extension cords running from the wall across the room for presentations, etc. Just my .02 :) Regards, -Abe -----Original Message----- From: k12osn-bounces at redhat.com [mailto:k12osn-bounces at redhat.com] On Behalf Of Joseph Bishay Sent: Thursday, January 18, 2007 5:02 PM To: Support list for opensource software in schools. Subject: [K12OSN] Networking a new school for K12LTSP? Hello, I hope everyone is doing well. I sit on a design committee for a new building. A major part of the building will be a K-8 school (200 students). The building will also have a day care, banquet hall, and a community area (youth lounge, game room, etc) as it is a multi-purpose building. We are just now getting to the point of getting into how the building will be wiring, and my goal is to make sure the wiring is compatible for maximum LTSP performance. Hopefully both the school and the community area will utilize LTSP. I'd like some input on what people have in their schools that has worked, has not worked, what they wish they had, etc. Any and all feedback is greatly appreciated -- both in terms of LTSP specifically and I.T. generally. Thanks very much.

If all you want is to upgrade LTSP, then dowload the latest "ltspadmin" and upgrade. If you want to upgrade the base OS, you *could* use K12LTSP v6 (which used Fedora Core 6 as it's base), but at this late date, you might have to completely start over, since it represents a major departure from previous LTSP versions (using muekow instead of a separate LTSP distribution).

Unfortunately, this is for imaging a bunch of Windows XP workstations ... but I have no control over that at this point. No experience with "Ghost 4 Linux" (http://sourceforge.net/projects/g4l), but it might do the job. I don't believe it "understands" NTFS partitions, so it would copy an entire partition (mebbe a bit smaller with compression), which means lots of storage would be required for backups. Install images would be rather smaller - you could make a standard install image in a few gigabytes, then expand it to the size of the target drive after installing it (I use qtparted on Knoppix). "Ghost 4 Linux" has a modified Knoppix CD image, so you could probably boot with that CD, do the backup or restore, then reboot to the Evil Empire (tm) OS.

It is predominantly Win2K. We are trying to run LTSP for certain labs of computers that typically use internet and word processing. All the students have home directories hosted on a single Win2K server. I have Dell workstation that is a few years old that I loaded K12LTSP version 6 on. I got it to authenticate users to the ADS domain. I installed pam_mount and setup an automatic mount in the Desktop folder in the linux home folder for each user. To get the K12LTSP to join the ADS domain, I had to leave off the ads switch and let it find the best way to do it. The ADS domain started years ago in mixed mode. It is still running that way, but only has Win2K and Win2K3 servers. The problem is that when I open the folder on the Desktop, it is empty.

Have a map of the new building and give one to the cable guys so that they can mark on it where each cable bundle goes to. That way you know which wiring closet to go to in case you need to do some work. Also, make a copy of the map the cabling crew makes and tack it in each wiring closet. One last tip is to make sure the cabling guys terminate the connectors correctly and not do a sloppy job. Ok, one more tip. If you have a computer lab make sure there are PLENTY of AC outlets (rated to take the load of all the PC's on at the same time) and not just the bare minimum. Get a Hound & Dog cable tracer and use it as a quick and dirty noise tester (along with its regular use). If they ran cables too close to Florecent lighting or other EMI generators you will hear it on the Hound (buzzing noise). That's about all I can think of at the moment.

I assume that both ESD and Pulseaudio support are included and that one would still have to get the Flash9 player/plugin from the Adobe Beta site, and that this is for the 2nd beta version correct? Those still running K12LTSP v5 32-bit should be able to use the source RPMs (and the dependant devel libraries) along with the Adobe Beta Flash9 player/plugin, am I correct? Forgive the rhetorical questions, but I think there is already a great deal of confusion about what works with what (K12LTSP v6 vs. v5, LTSP 4.2 vs. muekow, Pulse vs. ESD etc.) and thought that a little clarification might help.

This box has two sata 320g Hd,s. The OS is installed on the one drive. The second drive is blank. Can i create a raid1 array and make it bootable? Will this hose the boot sector of the hard drive? ive read through the manual and then called the mobo company. the first time the gentleman told me this is not possible. I called the next day inquiring about more questions,and this gentleman told me it is possible? I've never tried this scenario.The server still boots fine with the smart drive errors but the Windows logical disk manager does not "see" the drive to be able to go through the software raid process:(.

K12LTSP is still based on LTSP4.2 The next version based on Fedora Core 7 will be muekow-based. I am using K12LTSP6 and find it very similar to Core 5. However, as long as you have the latest version of LTSP 4.2, there is probably no need to upgrade to get sound working. I had Mplayer and Flash (older version) working fine with K12LTSP5. Now I have Mplayer and Flash 9 working well with sound. I have installed shockwave with Crossover Linux. With other apps I had some trouble with client sound in crossover (Powerpoint specifically), but I am sure others have had more success than me. I just tested Shockwave on the server. The sound works fine.

Thanks! Looks like my weekend is going to be busy. I'll try to answer alot of questions so far. My thin clients are based on the Via Epia 533 mb (Casetronic) with 128mnb memory and 15" LCD monitors so that isn't a problem. We do have some older recycled PC's, but ... everyone that says they have to have sound have the Epias. We have 10 Windows-based desktops (certain staff members that have to work with the state) and 3 wireless laptop labs. The school director has been very supportive, but also has 40+ teachers/staff and next year NCS adds grades K-4 (650 students) so we will be a K-8 charter school (1300+ students). All students/staff/teachers have individual login accounts. Maintaining this hasn't been a real issue for the most part (4-6 hours per week mostly, after it is set up) except for the sound issue. The school can get donated PC's (PIII 1GHz) with Windows 2000 for essentially no cost through a state PC-recycling program that numerous companies contribute their older systems, so I have a difficult time with making the case that upfront, moving to Windows is more costly. (I have my MCSE for Windows thanks to my real job, though I am actually an engineer and do the IT-stuff as needed) App-wise, we use StarOffice (site license for what, about $70.00 total?) and mostly opensource everywhere else (exception is Type to Learn and now UnitedStreaming). The state provides the student attendance/class scheduling software (requires IE at present though the next version is supposedly browser-agnostic). I have two Windows terminal servers to handle windows-specific apps. (one for teachers, one for students). My only other concern is that my switches may need to be upgraded (I have netgear equipment, 24 and 48 port switches with Gigabit links to the servers). The K12LTSP servers are all dual 2.4Ghz with u320 SCSI, 8Gb memory. I still have that issue where I can't use the hardware RAID at present, but ... will sort it out eventually. As mentioned, since sound works for things like tuxtype, I should be close to having it all in place. Haven't tried compiling from source in a long time, so ... we will see. :) I am a stickler on my licensing. Many of the OSS-friendly companies have a hard enough time without stretching the definition of what constitutes a system and user. I will contact codeweavers and see what options are available. As for next year when we add the other grades, I am talking with the IT director and the school director to determine how much support I can reasonably provide. If they stay with K12LTSP and minimal desktops, it can be done without much additional effort. Also, the IT director is coming along in handling routine day-to-day issues. If the schools goes completely to Windows, then they will need to add a full time staff person just to handle the sudden addition of 300+ desktop systems probably. That is one of the really strong points about the linux-based thin client approach: once you have it set up, it will typically just run without many issues. If I can just get through this deadline, then with the advances occurring with LTSP, things should be in very good shape for next fall. Again, thanks to everyone who responded. I will let you know how it turns out. And ... if I can learn enough, all of this would be very good to put on the wiki. I know alot is there, but a 'from scratch with this distro' approach can't hurt. Just have to find time.

They have a free-of-charge version now. I've installed it on a couple different machines, so I could give you pointers if you need it. Also, somebody mentioned upgrading to the latest version of LTSP on your current K12LTSP installation. I can probably help you with that, too. I upgraded LTSP on an Ubuntu machine and the LTSP installer lets you save the new LTSP tree w/o erasing the old one. For instance, you can have /opt/ltsp_old_version and /opt/ltsp_new_version. Then to switch back and forth between the two versions, it's just a matter of changing a few config files to give the proper location of the kernels and the root path, etc. -Rob (in NJ) --- David Hopkins wrote: > Thanks!

Both motherboards are identical. Only the graphics cards are different one is pci and one is agp. It wasn't a problem getting it to run. I haven't tried putting them on the same network and doing the load balancing thing yet. But I have come across a different problem. I have 3 hard drives. They are all 120GB but in bios two of them come up as 111GB and one comes up as 114 Gb. When I mirrored the master 111GB drive to the 114 GB drive no problem But when I took the 114GB drive and put it into another machine and tried to mirror it to a 111GB drive the bios wouldn't allow it. I guess I need to use the 111GB drive to mirror the master drive then put it in the other computer and mirror that 111GB drive to the 114 gb drive. But then if the 111GB drive fails and I need to mirror the 114GB drive... I will have to find another 114 GB drive or bigger I guess. It is inconvenient. The controls in the bios raid are limited, but I was wondering if there is any way to make the 114 GB drive into a 111GB drive so the mirroring will be more straightforward.

I just bought a SATA II drive which my mobo also supports. I know how to install the PATA II and move the /home directory to it, but I'm wondering if I should just use the SATA alone, or run SATA for the boot drive and put /home on the PATA. What would you do given the choice between these drives? Also, I don't have the time/energy right now to reinstall/reconfigure. I'm leaning heavily towards just putting /home on the new SATA and seeing what kindof performance gain I get. BUT I've got to wondering. Is it even possible to install the SATA and copy the PATA to it and then reboot and be in business off the SATA drive? If so, what's the procedure? I've used ~~~~~~~~~~~~~~ mkdir /mnt/newhome mkfs -t ext2 /dev/hdb1 mount /dev/hdb1 /mnt/newhome (cd /home && tar cf - .) | (cd /mnt/newhome && tar xpf -) ~~~~~~~~~~~~~~ To move /home to its own drive before. Would some variant of this copy a bootable filesystem?

If you don't want to reinstall, then go ahead and use the SATA II drive for /home. The reason is as follows. Yes, you can indeed copy the entire contents of that existing PATA drive to the SATA drive (cat or dd are both good for this), thus entirely replacing the PATA drive. However, you also will then have to tweak /etc/fstab to point everything from /dev/hdaX to /dev/sdaX. If you don't do it right, you get a kernel panic (can't find the root partition). Also, generally speaking, you've got to verify that all the drivers for SATA (this includes the generic SCSI driver, BTW, since SATA is seen as SCSI) are present in either the kernel itself or in the initrd; modprobe's not good enough at boot-time. I believe that this is already the case for K12LTSP, so you *should* be OK in that way. Now, if it were me, I would simply put /home on the new SATA II drive and go on with life. It's just way easier. Also, your performance will increase somewhat overall, since now you're spreading the workload across two physical spindles and sets of read/write heads. --TP From carl at snarlnet.com Sat Jan 20 03:56:55 2007 From: carl at snarlnet.com (Carl Keil) Date: Fri, 19 Jan 2007 19:56:55 -0800 Subject: [K12OSN] Swapping out a PATA for a SATA Message-ID: <45B19307.3020100@snarlnet.com> > > > * /From/: "Terrell Prude' Jr." > > ------------------------------------------------------------------------ > >Carl Keil wrote: > > >Hi Folks, > > > > I'm running my k12ltsp server off a single PATA drive.

I haven't used K12LTSP for a couple of years now because I haven't been in a position where I could, but I was using LTSP from the pre-1.0 days, always installed manually until you came along with K12LTSP 1.0 and saved me millions of man-hours. I've been on this list watching you ever since that time. You just keep chugging along on this project as you have for years, never stopping or slowing. I'm ultimately impressed.

The video part of the Flash 9 plugin does work, but sound does not. Note that, with the previous version of Flash, sound did work. Here's what I did: 1.) yum update 2.) yum install flash-plugin 3.) rpm -ihv http://repos.k12linux.mesd.k12.or.us/non-free/4.2.3EL-32bit/libflashsupport-0.1.0-2098.i386.rpm 3.) Close all instances of Firefox. 4.) Start up Firefox and surf to www.youtube.com. Play any video. Now, to make sure that sound in general hadn't broken, I fired up MPlayer to play a .ogg, a .wmv (I keep one for testing purposes), and a .mpg. That still works fine. I am running the KDE desktop, and it is configured to use ESD. My KDE sound themes still work, as does sound for TuxType. As another test, I attempted playing a local .swf that I have lying around (the "Come On Baby Run Linspire" spoof of the famous Doors song). I did this from within kfmclient (a.k.a. Konqueror). Again, video works, but sound does not. Sound did work before the Flash 9 upgrade. --TP _______________________________ Do you GNU!? Microsoft Free since 2003 --the ultimate antivirus protection!

I already had Gadi's sound package installed on some K12LTSP 5 servers. This (along with Gadi's and Jim McQuillan's help) was necessary to get sound working on a bunch of Dell laptops. But that was prior to the upgrade to Flash 9, and the libflashplayer.so that comes with Flash 9, broke flash sound, at least on my servers. I neglected to say which version of K12LTSP I was running in my previous messages, and Eric's quick fix of running 'esddsp firefox' probably works for 6 but not 5. For the record (and archive searchers including myself), I was able to get sound working again with Flash 9 using Jean-Michel Dault's Pulse Audio package at http://pulseaudio.revolutionlinux.com/PulseAudio. Download the source file, run make and make install, just as the instructions say, and sound under Flash 9 works. I installed the following before running make, but they're all available via yum: openssl-devel esound-devel pulseaudio pulseaudio-devel subversion The subversion package is needed to download the Pulse Audio source file from Revolution Linux. Hopefully, this info will be useful to someone in the future.

The trick to getting them to PXE boot is to update the bios. I had to download a dos exe program called softpaq and it makes a boot disk that updates the bios. Once that is done go into setup F10 enable network boot and you should be away. The hard part is tracking down and creating the bios update disk. Once you have done that though it's good.

Here is a workaround I played with last night - it looks like the 4.2.x EL rpm works with V5 - 1. Fresh install of K12LTSP V5 on server without sound card 2. Did the System Tools --> Software updater and updated all 3. Tried TuxType on Client - no sound 4. Did System --> Preferences --> More Preferences --> Multimedia Systems Selector - default output plugin - selected ESD 5. Sound worked on tuxtype on client, no sound on flash 6. Tried the mkdir /tmp/.esd & touch /tmp/.esd/socket flash 7 work around - no sound on client 7. Checked the flash version it - saw it was version 9 8. Tried the 6 version of the flash 9 sound workaround rpm - would not resolve dependencies 9. Installed the 4 version of the rpm - and flash 9 has sound on the client - http://repos.k12linux.mesd.k12.or.us/non-free/4.2.3EL-32bit/ libflashsupport-0.1.0-2098.i386.rpm I tried this out last night on a old donated PIII server and the sound seemed better than the flash 7 (but it was different machines).

IIRC, this is both their strength (as it allows them to clone any file system), but also their weakness (as it forces them to copy all those garbage bytes as well). Assuming you have physical access and hotswap ability of some sort, I would think dd might be more effective in this case (local SATA / USB2 / Firewire speed vs. slurpdisk over LAN). HTH, -dhbarr.

This is kind of off topic, but am guessing someone here has given this a shot , maybe. I stupidly built a server 2 years ago without enabling the onboard Adapetc raid,with intentions of trying the built in software raid on Windows 2003 server. I never got around to setting up the software raid in Windows 2003 logical disk manager. duhhh!!..Now I rebooted this server a few days ago and I am getting smart drive status errors at bios level. This box has two sata 320g Hd,s. The OS is installed on the one drive. The second drive is blank. Can i create a raid1 array and make it bootable? Will this hose the boot sector of the hard drive? ive read through the manual and then called the mobo company. the first time the gentleman told me this is not possible. I called the next day inquiring about more questions,and this gentleman told me it is possible? I've never tried this scenario.The server still boots fine with the smart drive errors but the Windows logical disk manager does not "see" the drive to be able to go through the software raid process:(. I would prefer to do the Adaptec raid (1). Anyone have any ideas on this?

The article talked about an alternative to the traditional network design that they claim offers both more bandwidth to the user and a lower cost. I've included a link and quick excerpt that talks about the bandwidth advantages of this design. Sam "Bringing increased bandwidth ever closer to the user" A new architecture known as fiber-to the-telecom enclosure capitalizes on the bandwidth capabilities of optical circuits. http://cim.pennnet.com/display_article/281158/27/ARTCL/none/none/Bringing-increased-bandwidth-ever-closer-to-the-user/ A small excerpt: "High performance is an additional key benefit of FTTE. Both the low- and high-density FTTE options provide excellent performance in terms of bandwidth delivered to the work area. In many enterprises, 32-port switches are typically deployed and configured with one 1-Gbit/sec fiber uplink to the ER. This provides each workstation approximately 31 Mbits/sec of average throughput (1 Gbit/sec divided by 32 ports). Even if the 32-port switch is configured with two 1-Gbit/sec fiber uplinks, the average throughput available to each workstation is only 63 Mbits/sec. In each of these cases, the backbone has insufficient capacity to carry the full traffic from all workstations, each running at their maximum rate of 100 Mbits/sec. This design results in an .oversubscribed. switch (32 ports x 100 Mbits/sec = 3.2 Gbits/sec required, where only 1 or 2 Gbits/sec is available). The FTTE low-density design offers the highest performance to the work area because the 8-port mini-switch is totally non-blocking. That is, excess .capacity. exists as 200 Mbits/sec remains on the 1-Gbit/sec fiber backbone to the TR when all eight ports are operating at 100 Mbits/sec. The switch is able to provide connectivity to all eight workstations requiring 100 Mbits/sec simultaneously, because the aggregate total from the eight workstations is 800 Mbits/sec and the uplink can provide 1,000 Mbits/sec. The mini-switch in the FTTE low-density design is .non-blocking. or .undersubscribed.. The high-density FTTE design represents a sacrifice in performance, but offers increased installation savings."

I did add the correct entries in the servers file for svn (in the global section) to tell svn to use a proxy. Maybe it is somehow related to mirrors possibly not honoring proxies? So, I browsed to the above UK site and manually downloaded the rpms. Then, trying to install mplayer fails wonderfully with many missing dependencies. Not sure how long it is going to take to resolve all of them at this point. Hmmm ....I also tried livna just to see what was available and can get the pre8 versions, but ... not sure about them (and still doesn't solve the recommendation to build mplayer from src). Maybe I will just come in tonight and start downloading all the rpm dependencies, but no guarantee I can get them installed in the right order? But .. closer to a solution.

Strange since I was able to compile the source code. I will check if there are updates that can be installed since I might just need them for compiling mplayer. Also, it occurs to me that in the past when I got the header incomplete message it was somehow related to the state proxy caching the download information, not to the local yum repositories. Anyhow, will have to track down the list messages on how to completely remove the yum info and also check that my proxy settings are set to force the state to not use any cached info. I did get the source code for mplayer, just need to install the codecs and such first (according to the README) before compiling.

Remember, the thin client itself isn't going out to the Internet. The thin client is simply a display station, and everything is running on the server. So, what you would have to do is block the *server* from going out to the Internet, specifically, the server's "outside" IP address. The approach I would try is putting, for example, an OpenBSD box in front of that K12LTSP server, and you'd then set up authpf on the OpenBSD box. Authpf makes you authenticate before being able to go out past it. But that's kinda complex to do. But unless you're very comfortable with OpenBSD and its PF rules, I wouldn't go this route. Another solution, and the one I would actually recommend, is to set up a second K12LTSP server that you don't allow to go to the Internet (you can block this server's IP address at your Internet router). Set up a bank of thin clients, label them "No Internet Access," and hook up these thin clients to this second K12LTSP server. --TP _______________________________ Do you GNU!?

Message-ID: <392216372.1169503616475.JavaMail.root@fepweb13> Since my district reinstalled my K12LTSP servers (version 5), my staff can no longer "see" files on their thumb drives, as if the drives have no data. I confirmed that staff could see and use those very same files before this reinstall. I thought maybe there was something not chosen in the packages like "enable reading of NTFS", however, aren't thumb drives basic FAT? One additional piece of information; the district made a custom kernel that includes proprietary nic drivers. I thought maybe when the new kernel was recompiled that something happened with the ability to see NTFS or..?? Any troubleshooting tips or steps on how to fix this would greatly be appreciated.

Just use: lpr -P some_printer where the value of 'some_printer' is the name of one of your printers. You can get a list of available printers by running: lpstat -l The same thing is required for printing within acroread. You can get by without the '-P printer' by setting a default, either per-user or system wide. You can use the 'lpoptions' command to set the default. Check the man pages on lpstat and lpoptions for more info.

Boot from Knoppix or first CD as single user and edit the file /etc/shadow to leave password field blank for root. While there you may also want to edit sudoer file to add your self as sudo with all rights. Restart the server and login as root with no password. Change root password.

Maybe a slight lag but not really enough to notice. Not nearly as bad as it has been in the past with other versions. Compared to a windows machine? Yes...some lag. Lo and behold....the hidden esd directory had gone missing. After recreating it and doing a "touch socket" within it all is well with the world again. Man...this is *really* annoying =) On a side note... I won't be rolling this out until summertime so there should be time to work out all the bugs. Perhaps another k12ltsp release by then as well. Caleb Wagnon Technology Coordinator Fordyce Schools ____________________ >>> "David Hopkins" 1/23/2007 7:06 AM >>> Caleb, Sort of off-topic, but ... do you notice a significant lag with sound in flash (or other video streams)? Otherwise, I would second checking that /tmp/.esd/socket exists. I have no idea why someone would code a requirement for a file to exist in a tmp directory that gets cleared periodically.

Figured it would be fairly straightforward. trying this rewrite rule in httpd.conf, but no go. RewriteRule ^/~(.*)/(.*\.(mov|qt)) rtsp://OTHER-SERVER:7070/staff/$1/$2 [NC,NS,L,T=video/quicktime] I've tried with and without the Type changing. I've tried with RTSP and with HTTP. No luck. With HTTP, and if I go to http://Main-server/~user/movie.mov the rewrite works and takes me to http://other-server:7070/staff/user/movie.mov but fails with a server error. IF I have the RTSP: rewrite, it just fails. Why don't we just stream the video from the same server? I don't know. I thought at first it had to do with the mime type, hence the T=video/quicktime part of the re-write, but that didn't seem to help the problem. Does someone want to point out the stupid thing I'm doing (how's that for a chance), or give me pointers on a better way? I think by putting the link as rtsp://other-server/.... it works, but we were trying to make it easy for the students. plus, the rewrite method would force the use of the streaming server if they *didn't* put rtsp://other-server.. as the embedded object. My forehead is flat from slamming my head into the table, if I need to clarify something, just ask.

I've found the source of this error and have boldly moved on to others (; Apparently, I needed a separate 'shared-network' declaration for each subnet. (before, my dhcpd-k12ltsp.conf had both subnets in the one WORKSTATIONS subnet) After this change, the client received the correct IP each time it requested. However, then, I received kernel panics, unable to mount root. I changed the /etc/exports file to the one as is attached, though I'm not sure that made a difference (I defined each mount and its allowed subnets separately instead of using 192.168.0.0/255.255.0.0). I restarted NFS and did 'exportfs -avr' to ensure the changes were taken. I DO get an OK now, though it is still trying to mount to the incorrect NIC. I think I've moved into NFS issues and DHCPD is now all set. (this is a 192.168.1.0/24 client on the 192.168.1.0/24 switch and 192.168.1.0/24 server NIC - I copied a separate i386 for the 192.168.1.0/24 subnet and called it /opt/ltsp/i386-1) Creating new ramdisk to hold our root fs...

NFS doesn't do any logging so I'm kind of fishing in the dark. Does anyone have any suggestions? I hope folks don't mind me attaching and being a bit wordy about this issue.

I love the new spotlight feature. Now to try it out. For the record, on my two-machine-test-setup, where one is the client and the other is the server and they're connected by just a crossover cable, the first time I started the broadcast tool on the server, as root, and with no users selected so the broadcast should automatically go to all clients (only one in this case) the window did appear on the client machine, but not on the server where it was initiated. I chose File-Reset->Broadcast which killed the window on the client. Then I selected the user, clicked Broadcast, and this time the window appeared on both the client and on the server, as it should. I shut it down, unselected the user, so no users were selected, clicked Broadcast, and the window appeared on both the client and the server, again as it should. So, something funny happened the very first time I tried it, but I was not able to reproduce the error. My rule of thumb is that if something goes wrong once, make a note of it but don't worry about; if it happens a second time, then I start to dig into it. Many incidents happen just once and as such, it's not worth the time trying to fix something that never happens again. I mention the missing window here just in case others see something similar. Thanks for all your work on this Robert. And thanks Eric for packaging it up.

All server Ethernet NICs, switch port, and client ports run at 100/F except for a couple of classrooms that run at 10/F due to overlong CAT5 runs. * K12LTSP software: All at version 5.0.0.; all are using Gnome as the desktop environment. * Browser: Firefox 1.5.0.7 at two sites; Firefox 2.0.0.1 at one. * Servers: One site has a clone server with an Intel L440GX+MB motherboard, dual PIII/500MHz CPUs, and 2 GB RAM. The other two sites have a Dell PowerEdge 1600SC server with dual Xeon/2GHz CPUs and 2 GB RAM. * Clients: New Internet Computers (NIC) CPU: Cyrix MII-266GP. RAM: 64 MB.

To me, it looks fine. However, what is interesting is that your 192.168.1.x client is looking for /opt/ltsp/i386-1 from 192.168.0.254 instead of 192.168.1.254. My guess is that there isn't a separate "option root-path" statement in each "shared-network" stanza. Remember that each DHCP scope needs its own pointer to find /opt/ltsp/. So you want it to look sort of like this, using my /etc/dhcpd.conf file as an example (I use 172.16.x.x networks): shared-network WORKSTATIONS-1 { subnet 172.16.1.0 netmask 255.255.255.0 { range dynamic-bootp 172.16.1.100 172.16.1.253; use-host-decl-names on; option log-servers 172.16.1.254; option root-path "172.16.1.254:/opt/ltsp/i386-1"; Then, of course, you'd just comment out the global "option root-path" statement above your "shared network" sections and bounce dhcpd. Try that and let us know. --TP _______________________________ Do you GNU!? Microsoft Free since 2003 --the ultimate antivirus protection!

In-Reply-To: Message-ID: > 2) What is the difference between solid wires and regular cat 6? Is > there a name for this specification? Cat6 is a specification on how much bandwidth a given cable can carry. Solid cable is just that, solid wires twisted into pairs, with 4 pair in each cable. Solid cable isn't as flexble as braided cable, but it will last longer. Braided cable is a lot more flexable (i.e. it bends better), often less expensive but looses more in the transmission. Braided cable take a number of thiner strands and braids them togeather. Any strand may be broken in one or more places, and still work (good in theory, good in specific uses, but due to how electricity works, not the best solution to everything). Having done a little looking around, I found several Cat3, 4 and 5 cables that are not solid, but I didn't find any cat6. > 3) Is it always the case that it's better to have a room with 4 drops > for 4 computers, rather than 1 drop and a switch for the 4 computers > to plug into? Yes, and the more the better. 20 drops per classroom is a good number. > 5) We're going to, due to the distances involved, have a primary > server room where the network cables terminate, and a secondary room > as well.

Even if you use copper for now, you will likely need it in the future. Not much to install now, but can be 10x the cost to run later. > 6) For wiring wireless -- this may be something we do in the future? > Can I ask them to run cables and power to specific spots in the > ceiling and then just leave it as is? Yes. > 8) How much of an issue are florescent lights? Our building is filled > with them -- should I make a point to mention this? Yes, make a point to mention it. Sometimes they are a major issue, sometimes not. Plan where you will run to avoid them if possible. Add some extra sheilding - say like low-voltage conduate - don't run directly over a light and it shouldn't be an issue.

In-Reply-To: References: <45B0FA52.8040501@paasda.org><200701191319.57625.ray@mission.lib.tx.us> Message-ID: 1) Just for clarification: Gigabit speeds can be attained over fiber optic media as well as electrical. There are also different specifications depending on the type of media that you use. But in general, when you hear a "gigabit backbone" mentioned, the idea is that you have at least 1 gigabit per second between your intermediary distribution frames (IDFs) and your main distribution frame (MDF). If you can get away with it, like I mentioned in an earlier response, try to have all of your cables terminated in one networking closet and you can purchase a single, larger switch rather than multiple edge type switches. However, this is only a viable solution if all of your horizontal cable runs are less than 90 meters. 2) You can have solid Category 6 cable or stranded. Solid cable has superior electrical characteristics. Stranded cables are more flexible, easier to work with, and can be moved around quite a bit more without breaking the wires inside as easily. 3) In the case of a managed network, the fewer switches the better. Not only does it make administration easier, but you have fewer pieces of hardware that can fail. Throw into the mix that by having switches in the classroom you run the risk of student sticking pencils in the fans and unplugging the power to the switches all day long. I would know... unfortunately we still have a school wired with several hubs in the fashion until E-rate pulls through and we can re-wire :) 4) Also ask them to see what kind of boxes they have for the floors and walls. I can't recall the manufacturer, but we have some really nice floor boxes which open up so that you can plug in all of your power and Ethernet cables horizontally, and then you can close the tops with the cables poking out through a slot similar to the one shown here: http://www.tlc-direct.co.uk/Images/Products/size_3/UVCSM3SLASH4.JPG 5) I might have a different opinion on this than Steven :) You can run gigabit ethernet over Category 5, 5e, 6, and 7 cabling up to a distance of 100 meters (or so). So 100 feet will be no problem at all. I would suggest running 2 cables between the MDF and your IDF for redundancy (you may want to read up on spanning tree protocol). Category 6 and 7 cabling will also support 10 gigabit Ethernet (amended in IEEE 802.3an). (If the building is being constructed now, you can have them lay conduit which is of sufficient size so that you can have more copper pulled down the road or even have some fiber blown.) 6) Absolutely 7) And make sure the labeling isn't cheap! We always have contractors try to slap some cheap stickers on which fall off in just a matter of days due to heat and/or humidity. 8) Definitely worth mentioning to the contractors, although they should be well aware of this. But if this is your first construction project, heed this advice: STAY ON TOP OF EVERYTHING. Trust no one! Make sure the right number of cables get pulled, make sure the cabling is up to spec (no sub-standard crap), make sure the drops are where you want them, etc. You're going to be paying them a whole lotta money, so you'd best get what you want :) -Abe -----Original Message----- From: k12osn-bounces at redhat.com [mailto:k12osn-bounces at redhat.com] On Behalf Of Joseph Bishay Sent: Wednesday, January 24, 2007 12:10 PM To: Support list for open source software in schools. Subject: Re: [K12OSN] Networking a new school for K12LTSP? Hello, I hope you are doing well. Thank you all for the responses -- I've learned a LOT about this topic. I'm going to be meeting with the electrical people in order to discuss this further. I've gone through the various emails and some small questions have arisen 1) Gigabit backbone -- is that just cat6 cabling or does this relate to topology? And if topology, what kind is the best for LTSP? 2) What is the difference between solid wires and regular cat 6? Is there a name for this specification? 3) Is it always the case that it's better to have a room with 4 drops for 4 computers, rather than 1 drop and a switch for the 4 computers to plug into? 4) I really like the idea of floor drops and power outlets where the network drops are -- thanks! 5) We're going to, due to the distances involved, have a primary server room where the network cables terminate, and a secondary room as well. Is it necessary to connect them via fiber? The distance between them is probably 100 feet. I'm asking because the hardware to convert fiber <-> copper is rather expensive. Is it not easier to run several cat6 and somehow bridge them? (technical details fuzzy, but I think you know what I mean! :) ) 6) For wiring wireless -- this may be something we do in the future? Can I ask them to run cables and power to specific spots in the ceiling and then just leave it as is? 7) Labeling each of the cables with numbers/room location with validation - I got it! 8) How much of an issue are florescent lights? Our building is filled with them -- should I make a point to mention this? I look forward to your responses!

Not really, as I agree with this. For me, its just a cost vs potential cost thing. 40m (~150ft) of multi mode fiber will run you about $75, plus another $75 to have it run along with the other cables that are slated to be run. So for a grant total of about $150 now, you have fiber that if you were to have installed after construction would likely cost you at least a grand to have wired. Looking at the bigger picture, it seems much more cost effective to possibly waste $150 now, than to possibly waste $850 later (thats 850 + the $150 it costs you now). You obviously have to calculate the likelyhood of needing fiber in the next several years, but if the odds are greater than about 1 in 6 that you will need the fiber link over the next 10 years, its the more cost effective solution.

I'm an electrician in France... so I want to give you some technical information. (For the time I take to type this... more information... sorry for rebondancy !) >> 1) Gigabit backbone -- is that just cat6 cabling or does this relate >> to topology? And if topology, what kind is the best for LTSP? 1.The main difference between 5 and 6 is that 6 require continued ground field protector... You can't leave it even on 1 cm... So you need specilised socket that take ground far behind.... Cable is the same except that the wire are a bit larger.... Be very careful on cat6, normalisation was not complete and not fully respected (2-3 year ago... may have change since) >> 2) What is the difference between solid wires and regular cat 6? Is >> there a name for this specification? 2. I think that the difference are in the wire... usually, we but only 1 wire in copper (*8 for 1 cable) for the wall... While for connection, we but many wire (smaller but many) (*8 for 1 cable) The first one are more difficult to install since the can't turn as well as the second... but the first one are better for connection (sometime, some wire of the small one get off and the over wich was not maitain any more go off as well) Secondly, it usually a bit cheaper. Third, he doesn't like to be moved all the time... Connections doesn't move if the wall doesn't move... There for the first one is usually much more reliable than the second.... but The second is much more easy to turn, and the different wire make it much more reliable in time if someone walk on it all the time... (as 1 break is not lost of connection) but it is a bit more expensive.... Therefore: The first one in the wall between socket, the second type between socket and computer... >> 3) Is it always the case that it's better to have a room with 4 drops >> for 4 computers, rather than 1 drop and a switch for the 4 computers >> to plug into? 3. More wire allow you to easily upgrade to more fastest network... I mean, usually, once the building is made, adding an extra cable is very difficult.... and 1 cable of cat 5 won't go over 1G (for very short distance), therefore.... even by putting a gigabit switch, there will be 1G for all the client....that are connect to the hub and client can take as much as 80Mg between them and the server... That the same between no brand giga switch that can go up to 2or3G and nammed that can pass-thru 8G and much more.... Remenber that cost is greater for switch than for cable (25? / switch <=> 80m of cable in france in cat5) and that power bill will consider that... (I don't think that it would be cheaper in consommation without talking of Backing up (ondulated)) >> 4) I really like the idea of floor drops and power outlets where the >> network drops are -- thanks! 4. We have completely recabled our school last year and I already miss some power (1 for screen and 1 for computer but printer, scanner, speaker, external hard drive, screen projector, phone and much more... We (in france) can't use multiple socket for safety of the children...) So I would say now 3 socket by child computer and 5 for the teacher would be the least... The same apply for computer socket... We tend to have network printers, Voip phone, normal phone (use the same wired) (and even laptop for some of us) so they put 2 socket for each teacher place... 3 should be better... Floor drop are not bad idears (but cannot be used in france for security), but what about 1 or 2 roof socket for projector, wifi access point... >> 5) We're going to, due to the distances involved, have a primary >> server room where the network cables terminate, and a secondary room >> as well.

For 100Ft, (30 meter) you can effectively run multiple 1G cat6 connection and aggregate them (need branded hardware that support fail/over multiple link) >> 6) For wiring wireless -- this may be something we do in the future? >> Can I ask them to run cables and power to specific spots in the >> ceiling and then just leave it as is? 6. For sure, leave them non connected for 30year than use them is you want.... Remenber that if you wan't to have a very high speed connection you vill have to have more than one cable or (better I think but depend of the technology evolution) 1 cable for each small area... Wifi is one... phone point can require as well one cable... (6 DECT on a wirelless spot wich use 2 wire) >> 7) Labeling each of the cables with numbers/room location with >> validation - I got it! 7. I would rather say on socket and on cable and not right at the end but 1m before (3ft) >> 8) How much of an issue are florescent lights? Our building is filled >> with them -- should I make a point to mention this? Yes, absolutely.... The cable can cross florescent lights (avoid) but never follow them The same apply for all magnetic field: Big electric Motor, electric tranformateur.... (If i remenber well, 10 light of this type of ligh can make your cables uselless... and that is for Cat5, 1G should be more strict) The same for high voltage... and even 110V can't be good for your transmission... >> >> More remarque 1. Fiber is fast and should be able to go up to 10G for 2fiber.... 6 give you 30G... Should be enough... 2. But as much fiber as you can, then as much cable and then if you are short in money, but empty pipe can allow you extension (if there not turning 3 time at 90? on 10 feet with 3 wire inside already and place for only one new) (french specification says that 30% must be free... on power cable and power cupboard) But for ethernet cable, I would rather says 70% free Let them from the cable road to each mising socket (should be possible to but either fiber (specific renforced) or simple cable) It is more easy to but a new cable in an empty pipe than to add an extra cable to a bigger one already fill at 30%... and specially because if it break, you have loose the one running.... Remenber that cost is mainly time... and is not double time to but two or three at the place of one.... If they are marked correctly you can leave them until you need them... 3. In our school, we have 1 cable for each soket to an computing cupboard... Then wire from the socket to a switch with half of the socket for now.... And over wire for phone to over socket going to the phone installation Therefore... ready to move to Voip Multiple phone wired between main cupboard and building cupboard (4 building on 200m / 600ft) And to finish: 4. 200 student * 80 Mo => 14G I don't think it worst installing more than 30G.... Technology is too quick to change... 5. Are you on different floor or are you on 1 big large place... ? This should help to determine topology: Taking back 100 Cable to one single room is much difficult than 50 to two small room on each side, linked with fiber or copper. The best I think is to have 2 place.... because you can but one server on each side equilibrating charge and reducing risk in case of a fire, an innondation or bombing and so on... More difficult to administrate some will tell... false with Linux, ssh deported session of X.... or simply with rsync.... for simple backup... I hope you won't spend your time behind your server screen anyway... 6. Power security on server room : 2 type of socket and 2 light system (protected with 2*2 different circuit) At least a lock on the door there and on the switch.... not with the classroom key... or the building pass.... A server is secure by network access and physical access ! Good luck >From france ----- Original Message ----- From: To: "Support list for open source software in schools."

I love the new spotlight feature. Now to try it out. Thanks Petre. Being a teacher myself I really think the spotlight feature is going to be very popular. When I did broadcasts before some students knew they could "zone out" because there was no accountability (no interaction). Now students tend to pay VERY close attention cause if I spotlight them and say "show the class how to do it" they are under the scrutiny of their peers. It's a super student based learning activity. I now have some students begging to be spotlighted so they can show off their ability to everyone else. It's really useful for programming classes. I can honestly say that Broadcasting with the spotlight feature now surpasses the functionality of an LCD projector (and it's free). BTW I have added the unlocking of the xscreensaver to 0.41.

I am *so* glad that we ran it in our schools. Given the fluorescent lights and the length of some of the runs, we would be toast without it. If you possibly can, definitely run some fiber. --TP _______________________________ Do you GNU!?

I did this in my new office. We get occasional power outages lasting just a few seconds to a couple of minutes, and my access point and phone never skip a beat. It's WAY cool.

You can put these on the same drop with proper QOS and make everything work, but it is a lot easier if you've planned a separate subnet for them and keep them as much as possible on their own switches. You'll want POE to run the phones with a central UPS, but most other things won't need it and you can get by with older switches that don't have all the latest voice QOS management on the data side if you keep it separate.

Basically, you need to make sure that there is only one DHCP server on that segment, and that the DHCP server has the necessary parameters for TFTP-booting the LTSP clients. Thick clients, like Mac OS X, MS Windows, and GNU/Linux workstations will be just fine; they will simply ignore the TFTP-boot parameters. If you don't already have a DHCP server on that segment, then the dhcpd included with K12LTSP will do the job very nicely indeed. As for IP, hostname, DNS, and subnet, that depends entirely on your own network. You might want to talk to your network administrator to get that information. --TP _______________________________ Do you GNU!? Microsoft Free since 2003 --the ultimate antivirus protection!

I'm curious as to the procedure for a 6.0 upgrade, and whether that's a good idea sooner or later. I know it's been a few months since the release of FC6, but have trolled #fedora enough to know there are always more issues for the early adopters. So, I have two questions. The first is: Is there a recommended upgrade method? (Is there still an upgrade option on the installation discs?) The second is: What are the benefits (other than AIGLX/compiz eyecandy) and the drawbacks (other than falling a release cycle behind thereby making eventual upgrade even more difficult)? - I am naturally more interested in the evolution of x86_64 packages and hope to see these more prevalent, though I understand the restrainers on flash and win32 codecs.

Unfortunately, it doesn't go into depth on what steps would make it work. I emailed Crossover about it, and Jeremy wrote back: "I'm pretty sure that the folks that have gotten it to work have done so just by tweaking either ESD or Arts settings (sadly, I can't remember which one). CrossOver does have a native Arts driver, although it's pretty rough around the edges, so OSS mode via either ESD or Arts might be better." We use ESD and Gnome district-wide. We tried esddsp with Crossover, but it didn't work. Does anyone know what settings need to be tweaked to get Crossover Office Sound to work with LTSP?

Olivier's description fits that: you need a license for each client machine. The fact that multiple copies are running on one machine, the server, is irrelevant. Make sure the administration knows this, that ANY time you start to venture into the MS world, it will cost more money.

I installed via freshrpms a version of mplayer, but it did not have the codecs required, so I then downloaded the src code from mplayerhq. I also downloaded the skins, codecs, and then installed all of the missing development libraries that showed up when running the configure script. This allowed me to finally run make and make install to get mplayer mostly working. I can playback either windows media or quicktime movies that I download from United Streaming from the command line , but, I can't launch the gui interface, even though I included the option to compile it. I have tried to troubleshoot using http://www.mjmwired.net/resources/mplayer-fedora.html The error message is below: Has someone that has manually compiled seen this issue? Also, how do I add mplayer to the menu system (we are using gnome)? The menu entry is removed when I uninstall the version that I installed via yum.

But, checking Terminal server licenses only shows 1 license (a single device cal) being required. Now, we have 50 licenses on the server, and over the last 4 years, only 6 have ever been used, one for each different device that has connected (4 other servers and 2 desktops via MS's TSclient). I agree that MS would probably take exception to the use of a Linux TS to tie in with their TS because it looks like it only pulls 1 license, but .. that is why I mentioned the device CAL issue. I still think that the way the licensing was intended was that each TS session requires a device cal for each device. This isn't unreasonable from MS's perspective where the remote devices are single user systems (their desktops) and thus each device corresponds to a user session, but ... if coming from a multi-user system, it appears they did not account for this scenario. I would probably still lose in court though :( Sincerely, Dave Hopkins On 1/26/07, Petre Scheie wrote: > > My recollection from previous discussions is that whatever is the most > expensive way to > do it, that's the way MS charges you, at least in regard to TS client > licenses. > Olivier's description fits that: you need a license for each client > machine.

Have you seen the bandwidth numbers quoted as being used by some of the terminal server applications? 100MB dedicated back to a switch is much better than 100MB shared by 4 computers which are each trying to pull 70megabits of data at one time.

It allows for redundant links, but does not add any bandwidth capability to the path. The second path sits idle waiting for the first to fail. What you are looking for is port aggregation, or port trunking. So instead of having qty 2 1GB links, with one sitting doing nothing you have one 2GB link. Or make it a total of four wires trunked to have a 4 GB/s backbone (four GB links all combined). Good quality managed switches support this. More thoughts: Even if you choose not to run fiber at this point, I would suggest that you leave an empty conduit/inter-duct for future fiber to be pulled in. Also be aware of conduit fill restrictions. You can not legally fill a conduit up as much as you would think and practically you can't pull stuff into a conduit later that already has wires in it without pulling the old wires out and then pulling the new and old back in together. Regarding size, here is a quote from http://cim.pennnet.com/Articles/Article_Display.cfm?Section=ARCHI&ARTICLE_ID=277768&VERSION_NUM=2&p=27 "So, which design comes first, the cabling system or the conduit system that supports it? Logically, the cabling system. Once the quantity and type of cables required at each outlet location is determined, then the conduit system runs should be sized accordingly. For example, two Category 6A cables from a telecommunications room to an outlet location would require a Trade Size 1 (1-inch) conduit based on the following from the 2005 National Electrical Code:" If you do fiber between the MDF and IDF rooms you could look at preterminated options. Then you just "snap on" a modular pre-terminated break-out adapter on each end of the run and don't have to do time-consuming terminations. Use 50um core multi mode fiber, not 62.5um, since 50 is the standard for 10GB/second transmission. Look at your power requirements for both the UPSs (not 500 or 1000VA home units) as well as the servers and switches. Often times you need several 30AMP outlets along with some 20s. Consider POE items attached (voip phones, security cameras) and how long you want them to keep running when the power goes out. Look at your cooling requirements for your MDF/IDF rooms. > > 8) Definitely worth mentioning to the contractors, although they should > be well aware of this.

Also see the following articles about school networks: "Nothing old school with this high-performance LAN" http://cim.pennnet.com/articles/article_display.cfm?Section=ARCHI&C=feat&ARTICLE_ID=275161&KEYWORDS=school&p=27 "A Grade A infrastructure for every student " http://cim.pennnet.com/articles/article_display.cfm?Section=ARCHI&C=feat&ARTICLE_ID=272214&KEYWORDS=school&p=27 I would look for a cabling install contractor who is a member of BICSI and who is certified by the manufacturer to install the wires/jack brand you choose so that you are able to get the warranty on your install. I like Panduit jacks and dislike Levitron, but there are other good ones out there. Make sure the wires+jacks can be certified together and you should get records of the certification/testing by the installer. You may also consider getting a network design consultant involved. It will cost you, but so will making easy to correct mistakes.

In-Reply-To: <45B8F25F.4090204@futuresource.com> References: <45B8F25F.4090204@futuresource.com> Message-ID: Hello, Thanks once again for all the insight! I'm going to be going back to the building committee with much of this in mind. I'm hoping this isn't a very silly question, but I am a bit confused. I have a question about the MDF and the IDFs -- where all the network cabling will be running back to. Now I know from various setups I've seen that often where all these cables terminate there is a rack with the hardware that connects to the switches and the patch panel. In our case while we will have a patch panel where the various Cat6 cables will come in and terminate. Assuming 4+ drops / room, we'll have many, many terminations. Now, due to the cost of rack-mounted equipment, and what we can afford/is donated to us, it is nearly 99% sure we won't have rack mounted units for the servers. Is this not a problem if they can't fit into that distribution centre (which seems to be not much larger than a big closet)? Is there a problem to have the servers (full size towers) in another room in the building and running cables to the distribution centre? Or will there be some sort of bottleneck? My apologies if this is an obvious thing. The second question relates to the server setup. Currently we have 12 computers running on 1 server. In the future building would it be better to set up different k12ltsp servers serving up everything (IE: clones) spread around the building (IE: 1 for school, 1 for daycare, 1 for youth lounge) or would it be better to have 1 k12ltsp server for the whole building, 1 for NFS mount /home, 1 application server for the whole building,etc. Looking forward to your answer Joseph From lists.john at gmail.com Fri Jan 26 16:52:53 2007 From: lists.john at gmail.com (john ) Date: Fri, 26 Jan 2007 08:52:53 -0800 Subject: [K12OSN] Virtual IPs In-Reply-To: <43080f460701252225g734f2a2dsc45406effecf717@mail.gmail.com> References: <43080f460701252225g734f2a2dsc45406effecf717@mail.gmail.com> Message-ID: <2be970b50701260852m616a25chb606c25d7acd6d3e@mail.gmail.com> How about running a local instance of Dansguardian? http://dansguardian.org/ John On 1/25/07, Mel Wade wrote: > > In working on securing our network we have come across a problem.

Yes. Terminal services (on 2003) can be licensed either per seat or per user. The per seat license is a per device license so every device that connects takes a license (doesn't matter whether it is linux or Mac or whatever). Usually it is more cost effective to go per device on the licensing because most people have more users than they have devices -- so 10 different users sharing the same PC only consume one terminal service CAL in per seat licensing; whereas they would consume 10 licenses in the per user model.

It is much easier to provide physical security, power, cooling, etc if they are located in an area that was designed for them. Also note that many servers have loud fans. You don't want them in your office. I know getting a larger room is harder than I just made it sounds (I've fought this battle with a new building), but it is a worthwhile fight. For a cheap way to deal with non-rack mount servers look at a Wire Rack shelf unit (example at http://www.spacesavers.com/wirshelun.html ). They are available at home improvement stores. Or buy low cost rack mount shelves. I've bought for a reasonable price from Gruber and used their "200 LB" shelves for servers: http://www.gruber.com/catalog/showcase/34-104400.html . They also sell on ebay. The physical location is not a bottleneck. The servers and switches don't know if they are sitting side by side or 50 ft away. The bottleneck would come from how the switches and servers are connected. You want (at least) a gigabit uplink to the switches from the servers and then a multi-gigabit (via trunking/port aggregation) links between the switches if they are large. If they are smaller then you are fine with just a single gigabit feeding a small switch. 100MB* 8 ports switch (each with one computer hooked up, pulling the full 100 MB) = 800 MBits/sec. This would be a fine situation to use a single gigabit uplink. 100MB*48 port switch (each with one computer hooked up, each pulling only 50 MB/sec-- half as much traffic as before!) = 2.4GB/sec of data being pulled. If the traffic was being pulled from three 1GB capable servers (in theory) your bottle neck would be the switch uplink rather than the servers. If you are in a cost crunch, and your general contractor, local inspector and everyone else involved will allow it, you might consider using volunteer labor to help or entirely run the wires to the rooms. You may have parents who are network admins or have this type of experiance. Even parents who don't can lend a helping hand when you a pulling a long wire run and putting temporary labeling on all the cables. It can be a great bonding experaince, a big cost savings, and fun! If you go this route you will probably want to run a short "training" session on wire pulling and have someone on site supervising who know what they are doing to make sure things get done correctly. Besides wiring whole buildings, I've even installed underground conduit and pulled a 1000 ft fiber and a 25 pair phone line between two building using all volunteer labor except for the backhoe.

This makes backup easier (all the important data is on the one server) and it also allows you to put cheep disks on your LTSP servers. Put the expensive SCSI RAID all on the one server that does NFS and login(with redundant power supplies, UPS, etc). This lets you build relatively cheep LTSP servers using dual core CPUS with lots of RAM and cheep low capacity IDE drives. All the servers should use gigabit ethernet though. Two servers seems to be a bad number. I'd either try to keep it all on one server, or divorce your /home and LDAP server from your LTSP servers.

On your server make sure your iptables are shut off,( for testing purposes). ' service iptables stop ' Now boot a couple clients and pause them after you see the MAC address at starting boot. Write down a couple mac addresses. On the server via vnc or NX or console as root in a terminal type the following ' ether-wake -D < mac address > ' the "-D" isnt necessary,though,(only for debugging) example, you see your MAC/ hardware address is 00:11:22:33:44:55 ether-wake -D 00:11:22:33:44:55 with the -D option you'll see the hex numbers being sent to the client machine's Mac address. your client should arise from the dead,,,:) try witha newer laptop that has WOL enabled on it for testing purposes so you know a router or something is not killing the " magic" packet. Hope this helps. This works flawlessly providing you do have WOL on each client. How old are the clients you are testing? Im wondering if say version 1 of WOL may be dodgey?If these are old old client machines. Let us know.

I know unless you tewak it, DG will block ftp sites,for example.Add the ident package to your K12LTSp server's as well as the same ident service to whatever you have for Windows boxes on your lan,and you'll have easy detecting of whoever is getting denied sites as their username in the DG logs.

I did figure out the problem. the streaming server is running OSX, the software buries the movie files in a sub-directory. plus, the server doesn't do ~ usernames. The rewrite is going to be re-writing to something like: http://other-server:7070/staff/$1/Sites/Video_files/$2 Right now, the main server is serving the pages, when we go back and try and figure it out, I should know more. We only had about 8 different things we were trying to straighten out before a demo, figured getting it to stream from a different box was the least of the worries.

This is as true of Fedora as it is of MS Windows or any other platform (Slackware and OpenBSD seem to be somewhat better about this, but still....). This is one of the benefits to the "EL" version of K12LTSP. You don't have to upgrade your entire OS just to keep up on your security updates. Here's how I approach the issue. Generally, any special tweaks that I have to make are somewhere in /etc or /usr/local//etc if I've compiled it from src. What I do is put all of these apps in a single directory, maybe /home/customtweaks/etc, and then I symlink that custom stuff from there into either /etc or /usr/local/etc, as appropriate. This also assumes that /home--or wherever else you're storing the custom stuff--is on a separate partition. For example, I have a custom /etc/dhcpd.conf so that I can netboot x86, PowerMac, and UltraSPARC thin clients from the same server. That's how I preserve it across Fedora releases, because I really don't want to re-write that thing over and over. And as for your homedirs, /home should always be on a separate partition for exactly this reason. If it's not, what I would do if I were you is pick up a second hard disk for your server and move all that /home stuff to it. Really. --TP _______________________________ Do you GNU!?

That said, schools could benefit from this. This is definitely applicable for those of you who asked about using K12LTSP as an email server for your students. We all know about the spam problem. Well, over this last week, I have been playing with OpenBSD's spamd as a possible solution. Basically, I put the spamd box in front of my (yes, GNU/Linux) email server. I have now reduced the spam count in my inbox from close to 200 a day down to...five. FIVE. This is without false positives. I have verified that by studying my spamd logs all week and comparing them to my real email server's logs. For those of you with small pipes to the Internet, this is *definitely* something you might want to consider. It saves you some bandwidth.

You don't need permission to run fl-tt to use the WOL python script. You just need to run the Write_MAC_Addresses command once from fl-tt. Once the file (fl_teachertool.maclist) is created you don't need to run it again unless you change a NIC or machine in the lab.

The per seat license is a per device license so every device that > connects takes a license (doesn't matter whether it is linux or Mac or > whatever). With this and the old thread recalled this is very much clear that you need TCAL's. Question really is can "per device" be taken to imply the server since the MS sessions control (or what ever it is called which refuses connection when numbers go in excess of registered licenses) reads all request coming from one server as one connection? Dave (and others) confirms that RDP sessions from all terminals under LTSP show as connection from one machine to Window$. SO while the M$ rep would want to improve his revenue (and history shows he will not likely interpret otherwise) the final decider could hinge on "What would be the situation if there are two RDP sessions launched form one client?" Do you need a license for every RDP session and not every seat(machine)? Else one license is sufficient as their software is only recognizing multiple sessions from single machine as one connection. Conjecture: While M$ rolled out per seat license to accommodate corporates and schools (where per computer there are many users) they perhaps did not envisage this sort of situation. Safe approach: What I would like to do is put synopsis across to a M$ guy and ask for a written reply. If in future it turns out I was given wrong advise then may be some claims could be pressed. Brave approach: I would say as consumers (customers) you should interpret what benefits you unless expressly prohibited. This is like people taking advantage of airfares / holidays at cheap prices because of wrong price listing by seller. Those that have booked and paid get the benefit. This of course is my view point and needs some more thought. -- Regards, Sudev Barar From fhkms at adelphia.net Sun Jan 28 10:45:51 2007 From: fhkms at adelphia.net (fhkms at adelphia.net) Date: Sun, 28 Jan 2007 5:45:51 -0500 Subject: [K12OSN] server hardware advice Message-ID: <25371639.1169981151213.JavaMail.root@web29> hi All, So, I've potentially been given the opportunity to set my children's school up with k12ltsp (still in the consulting stage at the moment). They have a liberal budget, but I think they can still spend signifiicantly less if they go with k12ltsp. My question is: if I was to get a server from Dell or IBM or some other maker, what should it look like for hardware configuration - how many hard drives, Ram, network cards ect? I'm thinking it would serve 75 thin clients. Also, It might be in the budget to purchase some of the ready-made thin clients. I'd like sound to work out of the box, and to not have video issues. Any recommendations on this? Thanks!

The Dell laptops we're using already have a BIOS setting which can be set to automatically turn on the machine at a designated time, but I've been told we can't use that. In light of the policy, I think a simple icon on the teacher's desktop that calls a script that turns the machines on would be best, rather than putting it in fl_tt. However, as mentioned previously, these Dell Latitudes (model C600) do not respond to WOL packets, or at least I haven't been able to make them work. Yes, the BIOS is setup, yes, I've run the debug switch, etc.; I've even tried using just a crossover cable between sender and client, to no avail. OTOH, I've got a iPaq that does wakeup! Oddly, if I use ltspinfo to remotely shut the machine down, then it will not respond to a WOL packet; it only works if the machine was turned off by hand using the power switch. I've seen mention of this on the LTSP list, but no resolution. As to a script that would run by cron or by icon to wake up a list of machines, you could do something simple like this: for x i $(cat room1.txt) do ether-wake $x # sleep for five seconds so clients don't all start at once sleep 5 done where room1.txt is a file that contains the list of MAC addresses of the machine you want to wake up. Put the above commands into a file, make it executable, create an icon on the teacher's desktop that calls it, and then the teacher just clicks on the icon and the machines will all turn on one by one.

I'm inundated with spam from such. Pretty common spam trick. I have postmaster, abuse and root are sent to my mailbox. I don't do a catchall mailbox. One simple thing that will greatly reduce spam is to use the realtime blacklist that blocks mail from China and Korea. About 90% of the spam originates from there. This is the listing from my blacklists file for qmail: -r dnsbl.tqmcube.com -r dnsbl.sorbs.net -r sbl-xbl.spamhaus.org -r bl.spamcop.net -r cbl.abuseat.org -r dnsbl-1.uceprotect.net -r dnsbl-2.uceprotect.net -r dnsbl-3.uceprotect.net -r combined.njabl.org tqmcube.com catches the bulk of the spammers. That is why it is listed first in my file. This might be too many to check on a heavily loaded mailserver. If I were to limit myself it would be the first two in the list. Anything that gets through the blacklists gets checked with spamassassin. I use the rulesets from saupdates.openprotect.com and check for updates nightly. My server is also setup to do spf checking. This mail project got started because spammers where using totalsense.com in their return addresses. Guess they took a liking to it. I was getting hundreds of bounce messages to non-existent mail addresses. Convinced me real quick not to do a catch-all mailbox. Implementing SPF reduced that by about 2/3 at first. Now I don't see any.

It just so happens that your users are connection with LTSP terminals, and the printers are attached to LTSP terminals. Other than that, it's really a printer management issue on the server. You want one users default printer to be printerA, and another users default printer to be printerB. Assuming that you've got your printers all configured in CUPS on the server, you can use the 'lpoptions' command to set a default for each user. Because a user may log into ws004 in the morning, and then log into ws005 in the afternoon, you'll need to call lpoptions each time the user logs in. the /etc/profile script might be a good place to put this. The magic scripting you'll need to add is something like this: case `echo $DISPLAY | sed s/:.*$//` in ws004) lpoptions -d printerA;; ws005) lpoptions -d printerB;; esac That way, each time a user logs in, it checks the current terminal that they are logging in with, and it sets their default printer accordingly. If you are using Ubuntu's LTSP, you can't use the $DISPLAY, you'll have to use another env variable, like $SSH_CLIENT, which has a different format. do: echo $SSH_CLIENT to see what the value looks like.

They have a liberal budget, but I think they can still spend signifiicantly less if they go with k12ltsp. My question is: if I was to get a server from Dell or IBM or some other maker, what should it look like for hardware configuration - how many hard drives, Ram, network cards ect? I'm thinking it would serve 75 thin clients. Also, It might be in the budget to purchase some of the ready-made thin clients. I'd like sound to work out of the box, and to not have video issues.

Try: lpstat -l -a to get a list of printers that cups knows about. The name that shows as the first word of each line is the name you want to use in the lpoptions command.

SCSI for /home and SATA for / Since it is the home directory that is going to be doing read write operations as that is where user data is this needs to be fast. SATA would server well for fast reads and that is why "system" directories can be on SATA. Ideally I would also put on SCSI (and any other tree path where data writes are going to take place) -- Regards, Sudev Barar From microman at cmosnetworks.com Mon Jan 29 02:14:26 2007 From: microman at cmosnetworks.com (=?ISO-8859-1?Q?=22Terrell_Prud=E9_Jr=2E=22?=) Date: Sun, 28 Jan 2007 21:14:26 -0500 Subject: [K12OSN] OT: just reduced spam by 95% with Free Software In-Reply-To: <45BD0311.70804@paasda.org> References: <45BBC838.5060502@cmosnetworks.com> <45BD0311.70804@paasda.org> Message-ID: <45BD5882.8010400@cmosnetworks.com> I will write up a document on this and email it to the list, then. --TP _______________________________ Do you GNU!?

If your K12LTSP server can handle it, why not just run spamd (which is just the SpamAssassin daemon, right?) on your K12LTSP server directly? I don't think there is a difference between OpenBSD's spamd and Fedora Core's spamd, is there? Nils Breunese. -------------- next part -------------- A non-text attachment was scrubbed...

Good question. Actually, there is a big difference, and a lot of people confuse OpenBSD's spamd with that of SpamAssassin, since the name of the executable happens to be the same. They are in fact different programs with different strategies of dealing with spam. They are not replacements for each other; rather, they are complements. --TP From nils at breun.nl Mon Jan 29 11:34:14 2007 From: nils at breun.nl (Nils Breunese) Date: Mon, 29 Jan 2007 12:34:14 +0100 Subject: [K12OSN] OT: just reduced spam by 95% with Free Software In-Reply-To: <45BDD167.8000909@cmosnetworks.com> References: <45BBC838.5060502@cmosnetworks.com> <4D3A947F-ADAB-4FC1-84A0-BF1B1E2505B7@breun.nl> <45BDD167.8000909@cmosnetworks.com> Message-ID: <1A04BC7A-6134-49FD-BCE8-674973D1B2D3@breun.nl> Terrell Prud?

Looks like 'just a collection of blacklists'. I'm not sure I'd setup a separate box with another OS just for that (different if you're familiar with OpenBSD), but yes, you might want to offload the load that filtering spam takes to another box if your K12LTSP needs all its power to serve your thin clients. I don't have a K12LTSP server at the moment, but I use SpamAssassin with dcc [1], pyzor [2] and razor [3] to fight spam on my servers (running Plesk with qmail as MTA) which works nicely. You could add MAPS zones (like spamhaus.org's zen.spamhaus.org, etc.) as blocklists or plug them into SpamAssassin for extra scoring, but make sure you know which ones you're using and why (they all have different policies and some include others). Also, make sure to keep your list of zones up to date, because a MAPS zone that no longer exists can delay your mail delivery pretty bad. If you happen to run servers running Plesk check out atomicrocketturtle.com's free Project Gamera [4] if you'd like to setup a dedicated spam and virus filtering gateway. Nils Breunese.

Yes, it is physically possible to get 8GB RAM into a box now, but you'll have to use 64-bit version of Linux and not all applications work under 64-bit; you're just asking for trouble, which is NOT the thing to do in the first deployment. If money is available, the best way would be to start with three servers: two terminal servers and one NFS server for /home. This way you can use the NFS server for users' home directories and have it handle authentication (use the smbldap script from David and Matt), and also provide those services for any Mac and Windows boxes. You can assign 30-40 clients to each LTSP server, and if it proves popular, you can quickly setup another similar server to handle another 30-40 clients. The kids can login on any terminal and their environment/setup/files go with them. For the LTSP servers, to handle 30-40 clients, get dual CPUs, 4GB RAM; and normally, SCSI disks are required for this number of users, but if user data is all on a separate NFS server (which should have SCSI disks in a RAID), SCSI may not be necessary on the LTSP servers (anyone want to comment on this?). Don't put too many eggs in one basket: Go for stability to begin with, not the maximum clients you can squeeze onto one box. Any time the system is down, people will remember that more than how much money you saved.

They have a liberal budget, but I think they can still spend signifiicantly less if they go with k12ltsp. My question is: if I was to get a server from Dell or IBM or some other maker, what should it look like for hardware configuration - how many hard drives, Ram, network cards ect? I'm thinking it would serve 75 thin clients. Also, It might be in the budget to purchase some of the ready-made thin clients. I'd like sound to work out of the box, and to not have video issues.

Not only is it hard to figure out the licensing--which means you spend a lot of time thinking about it, trying to figure it out, and time is money--but no matter which licensing structure you conclude, it then costs more money to implement, perhaps much money, money that most likely could be put to much better use. Do they *really* need this app, or do they just want it? Extra costs hurting the children? Ask them which teacher is going to take the paycut to pay for the software. Given those stark contrast terms, they might look hard for an alternative. Petre David Hopkins wrote: > Taking this further OT: And thus my concern that I might not win the > court case.

I'd look for someone who is actually running a Linux system, even if just one system, or just a desktop. IOW, you want someone who has done more than just fired up a Knoppix disk once. Experience with Perl, Python, or PHP would be a good qualification, perhaps mandatory. Questions to ask during the interview: -what kind of mailing lists is the candidate is on? -what sort of experience has the candidate had in supporting FOSS software--the point is to screen out those who are only accustomed to calling a vendor and expecting the vendor to fix everything. -what distros has the candidate worked with? Likes and dislikes about each--to screen out those who are just name-droppers. It also depends on what the principal wants the teacher to do.

Definitely a good mix of Linux experience, as a user, as an administrator, perhaps web administration experience(if that will be part of this role).

With all due respect, in the end I think your really going to regret this. The SMBLDAP scripts included with K12LTSP make this kind of 3 server setup fairly easy. I honestly think that in the short term a 3 server setup (auth/home, TS1 and TS2) would be a lot easier to figure out than setting up 1 server with nic bonding, and working out the bugs/ghosts that can come with it. Long term, I would say this is an even bigger mistake. The more workstations that get added to the building (and it WILL grow), the more difficulties you will have dealing with it on one server. On the other hand, if you start off with a 3 server setup, adding to this becomes really easy. With a 3 server setup its fairly easy to turn around and add more terminal servers, fat linux/unix workstations, windows boxes, mac boxes, or specific services boxes (mail, SQL, WWW, etc) to your network. Without this kind of a setup, this is a lot harder to do (and its more than likely that eventually you WILL want to do this) You should also factor cost into this. I think when you price this all out, a 3 server setup is likely going to cost you less than your single box setup, especially when you factor the larger switches and your setup time into it. Long term your administration will be easier with a 3 server setup as well. You will be able to add, remove, replace or upgrade servers as needed, and without down time, which you won't get with a single machine setup. I hope you think long and hard about this. ---------------------------------------------------------------------- Steven Santos Director, Simply Circus, Inc.

I just hijacked someone's thread because I want to ask a question. I bought two servers (putting the specs on the list is on my to-do list), mostly to have one in case the other dies. How hard is it going to be to set up one as an LDAP server and remote mount its /home on the other server so that both can be used as application servers? Everyone seems to mention 3 servers, with the LDAP/home server not doing any application serving. Is that because it's just easier that way or is there some gotcha I'll run into just over the horizon?

A single dual core is able to server up to 40 clients so it is possible that two dual cores would be able to just about handle this.

You can do two server load balancing with /home hosted on Server 1 and rsync'ed to the Server 2 in some place like /home1 fairly frequently. Server 1 normally should do NFS and the Server 2 running together can run load balanced on same (sub)network. If Server 1 goes down the second server can continue as soon as you have linked /home1 as /home Perhaps some scripting with NFS conditioning check can make this automagically happen. -- Regards, Sudev Barar From sbarar at gmail.com Tue Jan 30 03:12:35 2007 From: sbarar at gmail.com (Sudev Barar) Date: Tue, 30 Jan 2007 08:42:35 +0530 Subject: [K12OSN] 2-server setup In-Reply-To: <1170125912.10277.16.camel@200-8143-202-01.Jefferson.ketsds.net> References: <1170125912.10277.16.camel@200-8143-202-01.Jefferson.ketsds.net> Message-ID: <774593a20701291912q43ea2068qcebd48f26b209187@mail.gmail.com> On 30/01/07, Todd O'Bryan wrote: > mostly to have one in case the other dies.

We ordered from eWiz.com and each server was just less than $2000, not including shipping. We also got 2 switches (24-100MB + 2-1GB ports) for about $90 each. I've included the eWiz part numbers, not to advertise for them (although I have no complaints), but so you can look up the parts if you're interested 1 NEC1231_BL NEC 1.44MB floppy 2 OS-2210 AMD Opteron Dual-Core Processor 2210 1 CA-STCT01B Cooler Master Case (terrific case!!!) 1 MB-S2927A2 Tyan Thunder n3600B Motherboard 1 PS-EN0555 Enhance 550W Power Supply 2 D2667R2G4S 2GB DDR2-667 ECC/Registered RAM 2 HD-W740AD Western Digital Raptor 74GB hard drive 1 DRW-S182LB Samsung DVD+/-RW drive (with LightScribe) 1 MSI-P62TC6 MSI nVidia Video Card 2 FAN-A86G Dynatron A86G Dual-Core Socket F 2U fan A couple of caveats: 1. The fans are godawful loud. I had the maintenance guy drill a hole through my wall and I have them in a (fairly large) closet because otherwise it sounds like a hurricane in my room. 2. There are two sizes of heat sinks: 4" and 3.5". If you decide to order other fans, the motherboard uses the 3.5" fans. We accidentally ordered 4" the first time and were very frustrated when we had a whole system just waiting for the right size fans. Putting everything together was very easy and I can't say enough nice things about the case. It has plenty of room and plenty of ventilation.

I would also be concerned about network bottlencks when serving 75+ clients from a single server. Although you can do channel bonding, thus theoretically it should be possible, but I have never had much luck with it bumping the performance...

I think most of us miss an important point about running LTSP is that the files read writes processing etc are all happening on the pci bus and not network. Only screen refresh information is travelling on network. For "most" applications with 40+ people running sessions the total network load is seldom more that 10mbps in most my locations. For instance right now with 19 active connections iptraf report total network rates as 4796 kbits/sec Yes there are applications which still transfer large data to thin client for screen rendering but as I said most of the robust applications do not do this and in fact I find that in most of the LTSP networks the network load is actually way lower than in fat client network using central storage etc. IMHO -- Regards, Sudev Barar From balmquist at mindfirestudios.com Mon Jan 29 13:23:30 2007 From: balmquist at mindfirestudios.com (Burke Almquist) Date: Mon, 29 Jan 2007 07:23:30 -0600 Subject: [K12OSN] OT: just reduced spam by 95% with Free Software In-Reply-To: <1170021187.12906.12.camel@dbserver> References: <45BBC838.5060502@cmosnetworks.com> <45BD0311.70804@paasda.org> <1170016710.10856.4.camel@dbserver> <45BD0BAE.9080003@paasda.org> <1170021187.12906.12.camel@dbserver> Message-ID: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been using dns blacklists for a while, but I've never gotten SPF checking setup.

Good advice. > I concur with Steve and Robert. To try to put everything onto one server means you'd have to, among other things, use the 64-bit version of Fedora, and lots of applications are not currently compiled for that. If that one server ever went down, *everyone* would be affected; with multiple servers, fewer people are disrupted. Putting everything onto one server will most likely cause your project to fail and thereby (incorrectly) discredit the use of thin clients. Don't do it.

Is 192.168.0.10 being assigned to eth1 by your upstream DHCP server? Or did you assign that manually? Or is this the address you're using on eth0, the interface for the clients? In either case, having both eth0 and eth1 on the 192.168.0 subnet will probably cause problems. This can be fixed by changing the subnet used for the thin clients on eth0, but please clarify before we get into that. Gateway should not be 255.255.255.0; that's the broadcast address. The gateway address should be the address of the next device along the path to the internet, and is frequently the same address as the DHCP server that gives your server an address on eth1. DNS is usually set to the LTSP server, so at least what you've got is consistent. But please answer the above questions first.

I guess you could redesignate the LDAP master to the server you are not upgrading as well as moving /home to it, and switch their roles. I use a server which is dedicated to hosting /home and running as the LDAP master. Then, my K12LTSP servers are LDAP slaves (thanks to the wonderful script supplied by Matt Olmquist (?) and David Trask).

Powerpoint is going to be a worst case; it can be annoyingly graphical. But still, you've got enough fire power that I would think you'd be okay. (And I do agree that if you can get Impress workable, that would be best). One question: is it just Powerpoint, or do you see this behavior with Word as well? If it's the latter, then something is clearly wrong, and you should get in touch with us so we can fix it. With Powerpoint, it may be that there are templates that the students are using; if you can switch away to less graphically intense templates, you may find that things are more sprightly.

Since AD is primarily LDAP and Kerberos, it should be possible, and chapter 9 of "LDAP System Administration" by Gerald Carter (published by O'Reilly) has a pretty good step by step description of how to go about it. You will need administrative rights to the Windows server, since there will be some additional configuration required. BTW anyone using LDAP should be interested in the above mentioned book, it is a very good practical guide for many uses of LDAP.

Else as most of the newer hardware is having gig links I would use a switch with two gig links for servers.

Unless the two locations already share a common ground plane, you need to optically isolate them. Connecting two separate grounds will only ensure that any electrical potential will travel between locations.

This machine scales up by adding RAM and disks (so start with SOME extra cpu, just not as much as a monster LTSP server maybe). The LTSP servers OTOH don't need that kind of storage. Think of them as a screaming workstation. Lots of CPU and RAM. These scale up by increasing the quantity. You can have many relatively cheep and almost identically configured servers. This also lets you isolate network traffic also by not putting too many clients on one gigabit connection.

How did you set that up? There are two parts to implementing SPF. The first is easy and everyone should do it. A DNS record tells the world where email from a given domain should originate from. You can go to http://www.openspf.org/ for info an setting it up. There is a tool to generate the txt record for you. The entry for my domain is simple: "v=spf1 a include:centurytel.net ~all" Mine shows centrytel.net as the only host mail should originate from. Since I'm on a dynamic IP my server uses my isp mailserver as a smarthost. Implementing spf checking is different for every mail system. Since I'm using qmailtoaster ( http://www.qmailtoaster.com ) spf checking was part of the package. I have mine system setup for a hard reject on spf failure. If inbound mail is relayed through another server spf will break. There is yet another protocol that has to be setup called SRS. It does a header rewrite to show the path the mail took to get to you. That is now part of qmailtoaster but I've not implemented it on my system yet. I am acting as a mail filter for a couple of friends who use hosting services with no filters. Since their servers don't check anything SRS has not become an issue yet. I will tell you that mailing lists break just about every checking protocol. SRS would fix some of that if the list servers used it. I had to setup a special entry for this list because the list server software hoses several anti-spam checks.

Perhaps a "more stable" distribution like Centos as opposed to Fedora? And the machine can also be stripped down in the sense you don't need openoffice and other enduser programs. In our school we have 27 terminals and a couple windows laptops for teachers. On the terminals we run Gnome and mostly use Openoffice or Office XP. We also quite often use flash websites using Firefox. We are on a tight budget, so I have tried to do the best I can at low cost. I have currently setup 2 k12ltsp servers on 2 identical desktop machines. AMD 2500XP with 2GB RAM each. Each has a 120GB SATA hard drive and gigabit network. 1: RAID 1 Complete K12LTSP including hosting NFS /home 2: Complete K12LTSP on one drive and a second 250GB drive for BackupPC. I now have a spare 1.2GHZ AMD computer. Would it be worth putting an SATA2 raid card into that and hosting /home and LDAP there? How good it SATA2 with NCQ? Or is it absolutely essential to go for (way more expensive) SCSI hard drives? How much CPU power would I need for an LDAP /home host for 27 clients? Is 1.2 GHZ enough? And how much RAM? I know that BackupPC (rsync) uses a bit of cpu power, but because this machine would back up at night I guess it wouldn't matter much. Thanks.

But, I will find out exactly what templates they are using in PowerPoint to make this work. I also I can upgrade the backbone of the lab from 100mb fiber to 1GB fiber to give the terminals a little more oomph. Since this class is just Powerpoint, Word or Excel have not been tested with a load. But, just using Word and Excel by itself no big problems that I can see when I use it. One test I did was I opened Powerpoint Presentations in Impress and the performance was significantly better. That is to be expected since Impress is native to Linux though.

Subject: Re: [K12OSN] CXOFFICE cause High Load on K12LTSP 5.0 Hi Glenn, I'd get a ticket in with us to see if we can fix this for you. Powerpoint is going to be a worst case; it can be annoyingly graphical. But still, you've got enough fire power that I would think you'd be okay. (And I do agree that if you can get Impress workable, that would be best). One question: is it just Powerpoint, or do you see this behavior with Word as well? If it's the latter, then something is clearly wrong, and you should get in touch with us so we can fix it. With Powerpoint, it may be that there are templates that the students are using; if you can switch away to less graphically intense templates, you may find that things are more sprightly.

In case the other responses didn't completely spell this out, the advantages of a separate home/authentication server are that the software for those operations does not change frequently so if you build this box to be rock solid (RAID, dual power supplies, etc.) the others become more or less disposable since they don't take much individual setup and users can log into any of them. The desktop software does improve enough to make it worth installing new versions every year but you can use much cheaper systems and keep a spare for testing or swapping in as a replacement if something breaks. > The reality is that this school will not be completed for at least > another 2 years.

If you don't have a gig backbone you'd be forced to that topology but you still have a choice to do it that way if you want. -- Les Mikesell lesmikesell at gmail.com From robark at gmail.com Wed Jan 31 20:32:09 2007 From: robark at gmail.com (Robert Arkiletian) Date: Wed, 31 Jan 2007 12:32:09 -0800 Subject: [K12OSN] Re: Networking a new school for K12LTSP?

No. A gigabit card is 1 Gibabit/s (that's 1 billion bits per second). Each byte is 8 bits. So it maxs out at 125MB/s. A simple PCI bus can handle 133MB/s max. So 1 gigabit ethernet card can saturate a PCI bus (remember other devices are probably sharing the PCI bus). That's why not many manufacturers make gigabit pci nics. What you want is PCI-X or now we have the newer PCI-E. Server boards still use PCI-X as PCI-E is too new.

I'd want a gig of RAM to start with room to double if you need more clients. NCQ is pretty good on the newer SATA drives. The downside to IDE/SATA drives is the lower speed motors, having a single head for read and write, and lower QC for consumer drives. A good compromise would be the SATA Raptor drives. They are 10k RPM drives that are designed for server use. It's almost like a 10k SCSI drive using a SATA connector. Of course they have a cost between that of real SCSI and desktop SATA drives too. > > How much CPU power would I need for an LDAP /home host for 27 clients? > Is 1.2 GHZ enough? And how much RAM?

If you have the bandwidth, I'd take the 250 GB drive home and run BackupPC from there. That way your backups are offsite. Of you can put it on a fat client in a different area of the building. The advantage of this setup is that you really only need to backup the rig doing NFS and LDAP regularly. The only stuff worth backing up on the LTSP servers is the configuration data, if you made many customizations. That doesn't change much, so you can burn a restore disk of sorts for those, once you get them setup. > > Thanks. > Krsnendu dasa > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (Darwin) iEYEARECAAYFAkXBIb4ACgkQfqZR3ThMfXR5+gCfSoKf25AgOJAjII38crwBETt+ O6gAnjOj9kwAvA3YN8Q/BRwBvjep41v7 =B0mZ -----END PGP SIGNATURE-----
