I am new to this forum. Does anyone know anything about a problem with the ATI ES1000 and incompatibility with K12LTSP? During the dos screen it looks fine on the install, but when it gets to probing for hardware and finds the ATI ES1000, my screen refreshes to an UN-synced mode. I tried several different brands of monitors and same problem occurred. I DID find a message on an unrelated website about a RedHat install suggesting a change to the xorg.conf file to change the Driver name from "ati" to "vesa". Does anybody know if this works on the K12LTSP install? Thanks.

I believe this was the fix we applied on an older Compaq test server with the ES1000. An alternate solution is to disable onboard video and drop an old used 2MB PCI card in a spare PCI slot. Hope this Helps, -dhbarr.

Be advised that though the "vesa" driver works with just about everything, it is D-A-W-G slow. By design, it doesn't take advantage of any of the card's built-in acceleration. That's an issue with a lot of nVidious cards, too. However, take heart. AMD, the new owners of ATI, is releasing the specs for their video chipsets. Therefore, there may be a working driver for that ES1000 soon, if not already, included in the latest X11 releases. --TP From dahopkins429 at gmail.com Sat Dec 1 15:34:43 2007 From: dahopkins429 at gmail.com (David Hopkins) Date: Sat, 1 Dec 2007 10:34:43 -0500 Subject: [K12OSN] Advocacy and Success Stories In-Reply-To: <474FB53E.7080401@cmosnetworks.com> References: <1196169818.18506.81.camel@laptop> <474D8283.40303@candt.waitrose.com> <20071130002107.GA9281@hank.org> <474FB53E.7080401@cmosnetworks.com> Message-ID: Wow!

Note the title, "Support list for open source software in schools." Originally this was a list about K12LTSP, because that was pretty much all that was out there. The primary focus is still that. However, we also discuss any other open source software in schools, and we certainly welcome any discussion regarding, for example, Edubuntu and SkoleLinux. BTW, Power Macs make pretty good LTSP thin clients. K12LTSP supports this out of the box. So you might not have to throw them away. --TP _______________________________ Do you GNU ?

As I see it KPhone has support for both ALSA and OSS. We've always been content with ESD to this point. I guess we are going to have to delve into getting a server or two setup for ALSA support. Anyone tried hand editing the kphonerc file to dump esd sound module into KPhone? I can get KPhone connected on a couple of terminals but of course I get error " be sure your soundcard is not in use by another app". I'm about afraid to try and compile alsa into the working ESD servers for fear the ESD sound will " disappear".:-) I know there a few how to's on setting up ALSA to K12LTSP,but can you "switch back and forth" via the System> Multimedia Sound Properties GUI?

This is a fresh install, so it's probably less trouble to re-install. This particular situation will be dhcp/squid/dansguardian only (no client terminals, just feeding Windows machines). To fit in with the existing network, eth1 is 10.10.195.10 and eth0 10.10.195.11, and the DHCP leases on up from there. What is the best way to do this? We need to reserve 10.10.195.x on down. If a machine is on those lower IPs, can I just set up eth0 to be 10.10.195.0/24 and DHCP won't offer a lease on an existing IP? I am more comfortable with the traditional dual-nic install, but for no LTSP clients would a single-nic install be as good? thx, Scott S. -------------- next part -------------- A non-text attachment was scrubbed...

I would welcome pointers to more software options for our K-6 school. That would be helpful in advocating for LTSP. Edubuntu comes with a pretty good selection, I feel. It's a bit frustrating just starting out to know where to post. I have technical questions about ltsp and I'm using Edubuntu. So, I've been picking between the Edubuntu and ltsp-discuss lists. It's not always easy to know if an issue is related to the distribution or not. Perhaps wrongly, but I've somewhat assumed that the K12OSN list might have more long-term LTSP users (and more of a school focus). I also assume many people are subscribed to both or all three lists. > BTW, Power Macs make pretty good LTSP thin clients. K12LTSP supports > this out of the box. So you might not have to throw them away. The one Power Mac works ok -- just sounds like a Kerby vacuum when running. But most of the 60 or 70 machines are old iMacs. They work ok (still no sound due to pulseaudio/liboil "illegal instruction"), but are slow. The P4 1GB clients I have scream. ;) I'ld like to move to low-powered fan-less thin clients when possible.

Scott Belford) Date: Sat, 01 Dec 2007 12:07:19 -1000 Subject: [K12OSN] Schools and the OPM Addiction Message-ID: <4751DB17.2060901@hosef.org> I fear that far too often good-willed and well-intending education advocates fail to fully understand the extent of OPM addiction in the American education system. More successful advocates have learned to enable the use of OPM within the schools. They fund this addiction with enticing technology trinkets and strong-armed contractual agreements. OPM, Other People's Money, is a delight to use. It feels so good, and it spends so well. It is not to be confused with what most of us are left with, Money. It is hard to come by, painful to spend, and there never seems to be enough of it. When using OPM you'll take two of whatever, and make it a deluxe. When using M, you clip coupons. If you would like to succeed in helping most schools and education systems, experience shows that they need you to facilitate their OPM use. You must appreciate their appetite is voracious, and that if they do not use their entire hoard of OPM each year, they don't get more next year, as promised. Successful vendors succeed by supplying schools with OPM on a consistent and reliable basis. This is where the conspiracy lies, so take it for what it is worth. Some vendors offer luscious, enticing hardware that everyone wants. Though they use some fruit as their name, they still succeed in getting schools to eagerly adorn themselves in their regal iJewelry. Understanding how important it is for the children to see their schools wearing only the best, the public eagerly supplies sufficient OPM without question. Some is sold off to Vendors who in turn build more eye iJewlery. It could be, and it does get, worse. Sometimes the OPM trade is a bit more ugly. For those with squeamish stomachs, please put down your bialy. Some Vendors have managed to enslave our schools in barbed chains of sophisticated contractual agreements. In order to get the DEHLENIB hardware necessary to adorn themselves, they must commit to consecutive years wearing the same undergarments. In the past they could at least change these undergarments or add new hardware trinkets. Now they are contractually forbidden to make such hygiene changes. This becomes smelly. It is true that there are some schools that are trying to Free themselves from this OPM addiction. All the OPM abuse has given them very bad teeth, and now they need FLOSS. They are looking for the kind-hearted souls out there willing to help them stay OPM Free and well FLOSSed. This is where many of the more benevolent among us have invested our passions. However, we must appreciate that these recovering schools are usually the least capable of stopping the abuse of OPM in their districts, regardless of how noble and economical their story. So to you I say learn to use OPM, but find a way to ween our blinded and addicted schools. Forgive them for they know not what they do. Instead, show them how FLOSSing can actually help them to spend their OPM on other things, like more counselors and educators. While they too may be OPM users, perhaps they won't be. If properly educated, our youth don't have to be OPM users. By reaching out to our youth and our college students in non-academic environments(1), they can see the benefits of FLOSSing instead of using OPM. They will eventually be hired by those schools you have taken to lunch, intoxicated with OPM, and adorned with your own FLOSS filled Trinkets. You never know when they may want to open them up for a little cleaning. --scott (1)http://www.youtube.com/sctinc -- R.

Actually, the Power Mac client I was thinking of when I wrote the above was my orange iMac sitting in my living room! It's just about as fast as any other client I have. One of those other thin clients is a Sun Ultra 5 (270MHz CPU), and it, too, is a good performer because of its Fast Ethernet NIC. The most critical thing you need on the thin client for good general performance (e. g. OpenOffice.org and Firefox, not fancy 3-D graphics stuff like Compiz/Beryl) is a 100Mbps Full Duplex network connection. The server should of course have at least 1Gbps FDX. The built-in video, ATI 3D Rage Pro, will do nicely for that. Full-screen 320x240 video will drop a few frames, yes...but it does work. 640x480 hi-res videos, that might be painful.... > The P4 1GB clients I have scream. ;) > > I'ld like to move to low-powered fan-less thin clients when possible. > It would help keep up its "Green Business" status If you want to do that, then I would suggest Jim McQuillan's thin clients at http://www.disklessworkstations.com. --TP -------------- next part -------------- An HTML attachment was scrubbed...

The University of Missouri at Rolla is one of the schools that regularly competes at the Solar Decathlon in Washington, DC. It's where 20 schools compete to build the most efficient and forward-looking, but livable and comfortable, off-the-grid solar-powered house. The 20 schools transport their 500-800 sq. ft. houses to DC and assemble them on the Washington Mall. Rolla always makes a good showing, and this year was no exception. It was quite nice. Running a laptop computer, along with other "appliances", is part of the competition. Unfortunately, Rolla's laptop was running Windows XP, just like most other teams (I also saw three MacBooks). But the Universidad Politecnica de Madrid (yes, they brought a house all the way from Spain) did have GNU/Linux on theirs! And yes, they know all about what's going on in Extremadura. "OPM", I take it, means "Other People's Money?" The ultimate OPiuM, I'd say.... --TP From jkinney at localnetsolutions.com Sun Dec 2 03:59:20 2007 From: jkinney at localnetsolutions.com (James P.

I'm glad to see that a national tech ed magazine is putting more focus on Linux and OSS. Thanks for the encouraging words Scott and Levi! Scott - I'm a hapa-Hawaiian (don't ask how I got to be in the Ozarks! - long story), and my mother lives in Ewa Beach! Small world, eh? My tutu is from Niihau and I have ohana on every island. Haven't been back since 1994 though - too busy raising a family out here in the mainland... Scott you have land in Rolla? Next time you visit, "holler" at me and I'll look you up - perhaps we can do lunch or dinner! Levi - you're almost a neighbor too! My organization visits the hospital in Bolivar regularly as a role model healthcare system. I used to live in Rogersville (they didn't use Linux then), and I started my college career in Rolla... best 3 freshman semesters of my life! I believe we were required to take FORTRAN. And thanks to everyone on this mail list who has helped me through the years to create those LTSP labs in my school district. I don't know if those labs are even still functioning now that I'm gone... it would be such a bummer if that was dropped. But the guy they brought in after me wasn't a Linux dude - he shut down my Apache webserver and Sendmail email server and setup a MS environment (probably spent money that I was going to spend on client PCs to build more labs for more students). Oh well... The local hospital was looking for IT people and specifically an Educator, and I fit the bill. So now I do that... but I'm still promoting OSS and Linux in particular. We could save hundreds of thousands of dollars if we could migrate our org to simply switching to using Open Office in a Windows environment! Funny that when I left the field of Education, I immediately setup a Joomla server for a departmental blog/wiki/CMS. Soon after the Sr. Net Admin setup the free Windows SharePoint Services as a portal for the entire org. So I shut down my Joomla server - no need to double up the work we're doing. Now we've grown to need services that SharePoint "free" can't provide, but if we want the full package it's too costly! So, I'm back to beta-testing Joomla and Drupal for my department to test, as well as Moodle and TWiki (I tried MoinMoin, but the folks just didn't like it). This time I think the Sr. Net Admin (who is actually younger than me) is supportive of the idea and willing to put a virtual server online for me to install all these OSS applications on for the entire organization. Ironically, it will be an MS server, virtualized to run Linux as the OS... not the other way around! Funny, eh? The Sr. Net Admin has experience with Joomla/Mambo/Drupal, so that's a plus! Wish me luck with these new endeavors folks... and if you're a praying person, say a prayer for success on these projects. Saving this money means we're able to spend the money elsewhere on better patient care, or hiring more nurses or support staff. I hope it's OK for me to continue posting to this mail list, though I'm not using K12LTSP anymore. I learned all that I know about Linux (mostly) and OSS from this list. So I feel like it's "home" for me to talk about OSS and Linux here. Thanks to all of you for all that you do across the globe to help people and organizations experience the benefits and power of OSS. You folks are great! -- "miracles are a retelling in small letters of the very same story which is written across the whole world in letter too large for some of us to see." -- c.s. lewis -------------- next part -------------- An HTML attachment was scrubbed...

That being said, I have to admit that I too have been in situations where the data were collected first before thinking about the underlying statistical models. Without knowing anything about your data, I'd imagine that an analysis of variance (ANOVA) maybe couple with factor analysis may be the best approach. You can get the tools to do these kinds of analyses with packages like SAS, SPSS or Statgraphics, among the ones that I've used in the past. Instead of a spreadsheet, you may want to consider storing your data into some kind of DBMS. Filemaker is a nice one and MS Access can suffice too. Storing the data in this form can make the retrieval process easier when it comes time to feeding these data into a statistics package.

I'm glad to see that a national tech ed magazine is putting more focus on Linux and OSS. Thanks for the encouraging words Scott and Levi! Scott - I'm a hapa-Hawaiian (don't ask how I got to be in the Ozarks! - long story), and my mother lives in Ewa Beach! Small world, eh? My tutu is from Niihau and I have ohana on every island. Haven't been back since 1994 though - too busy raising a family out here in the mainland... Scott you have land in Rolla? Next time you visit, "holler" at me and I'll look you up - perhaps we can do lunch or dinner! Levi - you're almost a neighbor too! My organization visits the hospital in Bolivar regularly as a role model healthcare system. I used to live in Rogersville (they didn't use Linux then), and I started my college career in Rolla... best 3 freshman semesters of my life! I believe we were required to take FORTRAN. And thanks to everyone on this mail list who has helped me through the years to create those LTSP labs in my school district. I don't know if those labs are even still functioning now that I'm gone... it would be such a bummer if that was dropped. But the guy they brought in after me wasn't a Linux dude - he shut down my Apache webserver and Sendmail email server and setup a MS environment (probably spent money that I was going to spend on client PCs to build more labs for more students). Oh well... The local hospital was looking for IT people and specifically an Educator, and I fit the bill. So now I do that... but I'm still promoting OSS and Linux in particular. We could save hundreds of thousands of dollars if we could migrate our org to simply switching to using Open Office in a Windows environment! Funny that when I left the field of Education, I immediately setup a Joomla server for a departmental blog/wiki/CMS. Soon after the Sr. Net Admin setup the free Windows SharePoint Services as a portal for the entire org. So I shut down my Joomla server - no need to double up the work we're doing. Now we've grown to need services that SharePoint "free" can't provide, but if we want the full package it's too costly! So, I'm back to beta-testing Joomla and Drupal for my department to test, as well as Moodle and TWiki (I tried MoinMoin, but the folks just didn't like it). This time I think the Sr. Net Admin (who is actually younger than me) is supportive of the idea and willing to put a virtual server online for me to install all these OSS applications on for the entire organization. Ironically, it will be an MS server, virtualized to run Linux as the OS... not the other way around! Funny, eh? The Sr. Net Admin has experience with Joomla/Mambo/Drupal, so that's a plus! Wish me luck with these new endeavors folks... and if you're a praying person, say a prayer for success on these projects. Saving this money means we're able to spend the money elsewhere on better patient care, or hiring more nurses or support staff. I hope it's OK for me to continue posting to this mail list, though I'm not using K12LTSP anymore. I learned all that I know about Linux (mostly) and OSS from this list. So I feel like it's "home" for me to talk about OSS and Linux here. Thanks to all of you for all that you do across the globe to help people and organizations experience the benefits and power of OSS.

Funny, but sadly true. I find that like with any addiction, the problem starts with the dealers. They make this stuff sound too fun to not try. A quick example of how this hurts schools. We just had 3M give the school a grant to buy some technology. The teachers involved went to a seminar about cool new products in schools. The teachers decided the best way the money could be spent is with EBeam projection systems. They thought this could be as useful as SMART Boards but for a third of the cost. They ordered them. The teachers use OSX as their operating system this year. As part of my schools second wave of Linux integration we were going to move all teachers to Linux next year. EBeam is OSX/Windows only. So now thanks to this grant (OPM), and the flashy presentation by the dealers, we now have a huge obstacle to overcome with making these EBeam systems useful while still trying to switch to Linux. So our $5,000 grant (OPM) is putting our $60,000 savings and all the other benefits of switching to Linux in jeopardy. Other cases are where the dealers of the OPM provide the stuff the first time for free, but in doing so give us new addictions that we cannot afford. Sure we get new projectors, but can't afford to replace the bulbs or the system when it fails. We get software, but can't afford the upgrade cycle. This list could go on. Used wisely, there is no problem with OPM. However I believe the dealers are the first in the chain who need to wise up, then the users will follow.

That's why they're doing what they're doing. It is the *USER* of the OPM that needs to wise up and tell the dealer to go jump in the ocean. Sadly, the only thing that gets the vast majority of addicts to kick the habit is some major tragedy. It happened in Portland Public Schools in Oregon (the massive Microsoft audit threat). It happened to a major bottling company in Texas (do a Google search for "Chuck E. Owens"). It happened to Ernie Ball, Inc. In the case of Portland Public Schools, it's obvious that their pilot of GNU/Linux was a major part of why they were threatened.

You can repeat this if there are problems downloading. Then when you are ready for the actual update: yum -y update This part runs fairly quickly with all the packages already available - and you'll need a reboot when it finishes to load the new kernel. -- Les Mikesell les at futuresource.com From tsmith at geneseeschools.org Mon Dec 3 16:16:57 2007 From: tsmith at geneseeschools.org (Travis Smith) Date: Mon, 03 Dec 2007 11:16:57 -0500 Subject: [K12OSN] Joomla Message-ID: <4753E5A8.6ADC.000C.3@geneseeschools.org> I posted a few months ago about going with Drupal or Joomla. Well I forgot to give an update so here it is.. I ended up setting up a HP ProliantDL320 with 2 two sata drives in raid 1 (couldn't afford SAS) and installed joomla on top of Fedora 6. Everything has been rock solid, only time the server rebooted was when power was out for the whole day and my ups gave up. We bought a php calendar for 50 bones and thats it. I gotta say it felt good showing off the powerful open source solution to the rest of the schools in the county who have a tendency to have OPM addiction sometimes lol. I haven't found a home yet for a k12ltsp server in the school (we had 2 2003 terminal servers when I got here) because I haven't completely figured out authenticating to edirectory but I love the list and reading all the emails.

The problem is that during the spike, everything comes to a complete crawl. Since this behavior has only started recently, I am at a loss for why. I have not updated any packages nor added any. It is almost like some 'tipping point' was reached wrt files, perhaps related to a thread discussion earlier concerning open files? Has anyone else on the list seen behavior like this? And if so, have a recommendation on how to resolve it?

"Keep the user > addicted at all costs," whether via carrot...or stick, if necessary. In principal it seems that OPM is simply a NET, Not Enough Time, solution for many schools. It is that way here in Hawaii, and it is an appropriate fix. (geez, the metaphors keep coming) It does not solve the GROSS problem, GReatly Overpopulated School Systems. The bottom line, so to speak, is that FOSS advocates may want to focus on selling something as well as giving it away for free if they want their schools to 'buy' it. Philosophically, this requires understanding the OPM phenomenon. If you are going to promote the sizzle and smell of the steak, you might as well sell some meat. For anyone vaguely familiar with HOSEF's commitment to getting Free computer labs into schools and community centers, you will know that this assessment is made from the requisite and painful real experiences. I can cite several schools this past year that had been using Free computers labs, successfully, for years. After changes in teachers/tech coordinators, they came under new leadership. There was an acceptance and an eagerness to use the existing Free computers, and there was a good relationship with those in our community providing Free but limited assistance. Money was found, somehow, to buy new computers. The reasons cited, with regret, were that there was a need for more immediate support. Rather than expensing a fraction of the cost of new hardware for locally born and bread support, it was expensed on bling. For this I fault myself for not creating the opportunity to spend that money with us. I do not fault the dealing vendor. I do not fault the using customer. I fault me, the social entrepreneur, who failed to provide a solution for the problem. I certainly do not excuse what I see as a misuse of OPM, but what alternative did I leave them with? > > --TP --scott From peter at scheie.homedns.org Tue Dec 4 00:35:56 2007 From: peter at scheie.homedns.org (Peter Scheie) Date: Mon, 03 Dec 2007 18:35:56 -0600 Subject: [K12OSN] Re: Schools and the OPM Addiction In-Reply-To: <20071203140748.M56602@winonacotter.org> References: <4751DB17.2060901@hosef.org> <20071203140748.M56602@winonacotter.org> Message-ID: <4754A0EC.50102@scheie.homedns.org> BTW, what do Smart Boards cost?

And if so, have a recommendation on how to resolve it? I have a very similar server and I also had high load averages with FF and flash sites with 30 users. I have switched to Opera and it has made a big difference. Opera is very configurable in terms of global settings which is a plus. All flash processess run at nice 19 so the system runs much smoother. The only sad part is Opera is not Open Source.

I'm not sure there is any pressing need to do this update at all, but when an update installs a new kernel and sets it as the default, I usually like to reboot the machine at a time I can go to the console and select the old one if there is a problem. Otherwise there's a rare chance that some change won't work on your specific hardware and it won't come up after you lose power in the middle of the night and no one is around. This is more common on fedora, though - Centos is pretty well tested before anything is releases. -- Les Mikesell les at futuresource.com From jkinney at localnetsolutions.com Tue Dec 4 14:54:43 2007 From: jkinney at localnetsolutions.com (James P.

As a matter of policy, the 'enterprise' versions (RHEL, and thus Centos which is a direct clone)) do not do version level updates within a distribution release life. With minor exceptions they just backport security and bug fixes to the released version for their updates so there are no surprises or behavior changes.

I haven't installed it in my lab yet, but it was one of my big selling points on the lab that we had support from one of our more popular vendors. Huck, even the Smart Board itself is only $1400, the overall cost with project, mounts for projector(if you ceiling mount), cables (RCA cables for connection to VCR/DVD, longer video cable, USB or serial extender, possibly even sound off the computer), and installation (we're worth something right ;-) ) is about $3000 for us at least. Our teachers always ask for them too, but most have had to acquire them through grants like eMints or METS(STEM to most of you, but apparently that's a controversial word in Missouri), and had to go to training.

I think it was installed as a k12ltsp 3.x version, then had the updates that were available for RH 7.3 applied - until there weren't any more updates.

I have had a couple widescreen monitors that I have tried to get working on fat clients before, with much headaches. I had to Google for a few hours both times to find settings for that particular brand and model monitor. I now avoid buying widescreen monitors at all costs. But since you have one, I've found that liveCD's are usually the best at figuring this stuff out. Try plugging the monitor into a fat client somewhere and boot from a live CD. Then if it works steal the monitor section and put it into your custom xorg.conf file. This might be your best option. Otherwise search for your particular monitor brand and model in google along with xorg.conf. Maybe you'll get lucky and find a line to steal.

And if so, have a recommendation on how to resolve it? For what it is worth I don't think my processor usage spiked when the open file limit was reached. However things did slow and prevented any new logins until enough users logged out and the file limit was no longer exceeded. The limit I believe was due solely to the fact that I use LDAP users. If you don't use LDAP it is unlikely that you see this problem, I also had 75 or more concurrent users to reach this limit plus email sessions from a different server. However if you use LDAP you may just want to try increasing the file limit to see if it helps, you need to reboot the server to be certain it takes effect. I assume the amount of students concurrently logging in hasn't changed. Did you or the students change the homepage? If so the extra graphics loading of if the new pages contain flash, this might be causing a problem. Are there any stale process left on logout?

That box should carry about the load you have (I would say max at 25) but don't try adding more. The limiting part is the RAM. In order to really go beyond what you have now, you will need more RAM, a 64-bit OS and another 1Gbit NIC to provide downstream data to the clients. 8GB RAM will just barely cover 100 clients with minimal flash uses and don't even try streaming video for more than 2-5 students. The 4GB you have will happily work out with 30-50 clients (if you have the full 4GB) under similar loading issues. OOo is very usable (good threading) and flash has been scary.

I have the specs for my monitor, and I plugged them into a modeline generator that is posted on sourceforge, but the resulting modeline didn't work. I'm a little confused, though, whether I'm supposed to be specifying the X_HORZSYNC and X_VERTREFRESH along with the modeline. I think I've tried all combinations and none worked (but I could have missed something). Anyway, I'll google for modelines for my monitor and will surely report back if I am successful.

That would give > us more reason to upgrade... Distributions - especially the ones labelling themselves 'enterprise' - generally don't do major version upgrades because of stability and ease of upgrading for users, as there is no need to migrate configuration settings etc. They usually only backport security fixes from new versions to the version they're shipping in the supported distribution releases. If they would just package every upstream release, RHEL (and thus CentOS) would probably be a whole lot less stable. This Red Hat article explains this pretty well: http://www.redhat.com/security/updates/backporting/ Of course you could always go Gentoo or compile everything yourself, but I really wouldn't try that in a school or business setting. I set up a K12LTSP 5EL server and it is rock solid. It is pretty comforting to know that I can theoretically leave this server running the same setup for the next 7 years if I wanted too. Yum will keep the current versions patched and I'll never have to worry about changing config files or other glitches that come from moving to newer versions of software. Fedora is of course moving a lot faster that RHEL/CentOS, but CentOS lets me sleep at night and I value that very much. :o) Nils Breunese. -------------- next part -------------- A non-text attachment was scrubbed...

In the firefox *.default directory, several files get changed when I log onto the different servers. This includes compreg.dat, xpti.dat, key3.db and some others. I know if I change compreg.dat to the version created by the other server, FF takes 30-60 seconds to start. But ... that is not the only file that has to be tracked. Any other ideas on how to get this to work? I never had this particular issue with the 4.2 Fedora version, but then all my servers were identical OS.

If IP printer you should check if the printer is set up with the same IP and config that applys to your terminal network. I had the same problem (last issue was with the printer network card that needed to be replaced). If CUPS shows that this IP is busy it may be that it just was unable to connect to it.

Message-ID: <47565DA3020000BC0000896A@wusdweb.wusd.org> I work for a medium sized school district in Northern California, we have been using LTSP for almost one year now. I will say that it has been a bumpy ride and there has been a lot of frustration along the way, we a just at a point where the performance is acceptable but we have a special case where we have to use Citrix to present one windows application called Reading Counts, and the performance still leaves a lot to be desired from that side of it. We currently have one whole school using Wyse Thin Clients and LTSP, this includes a 24 station lab and I think about 25 teacher workstations. We also have another 34 workstation lab at another school. That being said I think LTSP is great! Cody >>> Bill Moseley 12/03/07 9:17 PM >>> Anyone in the Bay Area using LTSP in a school setting?

I second that. And according to this list, the CentOS version of K12LTSP (the "EL" version) is apparently pretty popular, exactly for that reason. I can tell you that it is slick as ice. My home server still runs the CentOS 4 version (now 4.5, of course), and it has yet to fail me. Fedora's just a little too "bleeding edge" for me, for this task. For doing demos, I used to use the Fedora version of K12LTSP, due to the extra eye-candy. However, even for my demos now, I find myself using the CentOS 5 version (good eye candy there, too), and it is what I recommend for people actually doing a production K12LTSP deployment. This is true even though the new Fedora 8 is an absolutely gorgeous GNU/Linux distribution to use. Now, that said, I'd gladly use Fedora 8 (or Kubuntu Feisty/Gutsy, for that matter!) in a heartbeat instead of Windows XP/Vista for imaging a lab of thick-client desktops in the graphic arts lab, *precisely* because of the eye candy. This is because thick clients w/ hot video boards can handle things like Compiz Fusion better, *AND* there are now 3-D accelerated Free Software drivers for the ATI boards (thank you, AMD, and it's about time!). Remember the function of a graphic arts lab; you need lots of CPU, GPU, and DRAM. Just make "the perfect Fedora workstation," with GIMP, et. al., and blast that image to your 30 thick clients. --TP From phanh at canby.k12.or.us Thu Dec 6 01:35:03 2007 From: phanh at canby.k12.or.us (Hung Phan) Date: Wed, 5 Dec 2007 17:35:03 -0800 Subject: [K12OSN] Remote connection to K12LTSP v6 Message-ID: Hello, folks Hope someone can help me with this issue.

Seems like that either you are trying to run network through a hub instead of a switch or some srvice is broken. Best would be to also run a terminal on the server to see what is with $tail -f /var/log/messages Most likely your dhcpd service is not set up correctly. -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there.

To review I have a dual quad core 2.66Ghz Xeon box (8 cores), 6 300GB SAS drives in RAID10, 16GB RAM, and 6 GB nics teamed with adaptive load balancing. The the network is configured there are about 15-20 machines per GB connection to the server. This is also running Edubuntu 7.04 with LDM_DIRECTX=true (no encryption) and the linux-image-server kernel under 32-bit to recognize the added RAM. So I set out yesterday to see how well my setup would run TuxMath on 30 clients simultaneously......not good. I started up 10, things looked great, CPU load averages under 10% and RAM under 2 GB. Then I started 10 more, CPU under 25% (starting to get high), RAM under 3GB, and still moving at a decent speed and loading quickly. Then I started 10 more, all hell broke loose :-( My CPU average started climbing drastically, the server came to a halt, all the clients that were running slowed way down, I couldn't quit any instance of TuxMath. The clients would respond to the point of exiting the game, then clicking quit, but the app stayed open and would not close. My CPU average climbed to 148% (Not sure how that is possible) with all instances of TuxMath at the quit screen. So even with all instances of TuxMath no longer moving graphics, but just sitting at the quit screen, my processor use still kept climbing, while RAM usage was still under 4GB. The only way I could get the system to recover was by killing all instances of TuxMath. So, I don't think all the problems users are seeing with TuxMath are related to network issues. It appears 15 or so instances of TuxMath on a single machine are the max due to escalating processor usage. The usage seemed to grow exponentially over time with the same amount of instances running. And once overloaded, the system can't recover, even when there are no more moving graphics. And given my system can handle 75 simultaneous Firefox sessions with Flash while switching back and forth to OpenOffice (on-line games until the teacher walks by) without breaking a sweat at 1280x1024 resolution, I'd venture to say the limitation is in the TuxMath code. Another note, I also noticed for every workstation 3 instances of TuxMath showed up in htop, and two of those processes were under 1% of usage, while the third sucked all the power, maybe this is a hint to what is going on. In this lab there are also 30 machines, 15 on one 1GB connection, and 15 on another. So I'm fairly certain network load was never an issue, all problems seem to point to excessive draw on CPU cycles. No offense meant here to the programmers of TuxMath, it is great software and my kids love it. I just hope this sheds some light on what is happening in a multiuser environment. If anyone else has some suggestions on something to try, let me know. It may take a few days to get the lab free and test, but I'll test it.

That's not good news as everyone I see whose seen tuxmath goes ape over it (especially the kids). The version that ships with K12LTSP is a bazillion years old (the abandoned version). The new version is 1.5.8 (tux hides in igloos and cities are not destroyed, includes "lessons" and does negative numbers!). The code is essentially unchanged at the base level (SDL is an easy cross platform toolset but is very inefficient). I don't have access to a large client count at the moment but I'll check the new version vs. the old version on Opteron systems ASAP. I'm really floored that the hardware you threw at this test choked so badly. I suspect that the different memory management processes between Opteron and Xeon will show up here (my testing last year showed an average performance boost of 30+% in thin client speed between Opteron and Xeon - Simultaneous launch of 24 OOo instances took 65 seconds on Xeons and 42 seconds with freshly booted servers and client. Speed up was even more dramatic with cached copy).

I did not even think about the TuxMath version, here is the output of the Edubuntu repository: Package: tuxmath Priority: optional Section: games Installed-Size: 2052 Maintainer: Ubuntu Core Developers Original-Maintainer: Holger Levsen Architecture: i386 Version: 1.0.1-1build1 Depends: libc6 (>= 2.5-0ubuntu1), libsdl-image1.2 (>= 1.2.5), libsdl-mixer1.2 (>= 1.2.6), libsdl1.2debian (>= 1.2.10-1) Filename: pool/main/t/tuxmath/tuxmath_1.0.1-1build1_i386.deb Size: 1420908 MD5sum: 8476a921bca0b36584f1b823d849dee3 SHA1: 738c9b966e32350564b3d776fb9117688afef6e8 SHA256: 793faa95d45091a22477ff930cdc68723983fb94a06d3a9d1beebbbcf09efb60 Description: math game for kids with Tux "Tux, of Math Command" ("TuxMath," for short) is an educational arcade game starring Tux, the Linux mascot! Based on the classic arcade game "Missile Command," Tux must defend his cities. In this case, though, he must do it by solving math problems. Bugs: mailto:ubuntu-users at lists.ubuntu.com Origin: Ubuntu Task: edubuntu-live So it appears the version is 1.0.1-1build1? I'm guessing that is fairly old. Maybe I'll download the new version and give it a try. As far as memory usage, I don't see any problems with concurrent Firefox and OpenOffice and 75 users, and RAM usage with those users and TuxMath never get above 4GB. With other things we can get to 6GB usage and no slow downs at all. I really don't think this is a RAM or memory problem, but the code hogging CPU usage. However I will state I'm likely not educated enough to make an accurate assessment, but the data I found seems to lean that direction.

Under load run top and hit the #1 button to see all the cores loading profiles. Now hit "j" and look at the "P" column. This will show the last cpu number a process was running on.

Try the development repo here: http://alioth.debian.org/frs/?group_id=31080 I compiles the new 1.5.8 on my Opteron test machine and it's quite speedy (note: one user - me). Code still has dead loops in it to deliberately slow it down and they are hard coded and not based on cpu speed or timed loops. so the game is faster on a fast machine and slower on a slow machine with both being equally loaded/unloaded. > > Package: tuxmath > Priority: optional > Section: games > Installed-Size: 2052 > Maintainer: Ubuntu Core Developers > Original-Maintainer: Holger Levsen > Architecture: i386 > Version: 1.0.1-1build1 > Depends: libc6 (>= 2.5-0ubuntu1), libsdl-image1.2 (>= 1.2.5), libsdl-mixer1.2 (>= > 1.2.6), libsdl1.2debian (>= 1.2.10-1) > Filename: pool/main/t/tuxmath/tuxmath_1.0.1-1build1_i386.deb > Size: 1420908 > MD5sum: 8476a921bca0b36584f1b823d849dee3 > SHA1: 738c9b966e32350564b3d776fb9117688afef6e8 > SHA256: 793faa95d45091a22477ff930cdc68723983fb94a06d3a9d1beebbbcf09efb60 > Description: math game for kids with Tux > "Tux, of Math Command" ("TuxMath," for short) is an > educational arcade game starring Tux, the Linux mascot! > Based on the classic arcade game "Missile Command," Tux > must defend his cities.

Under top it tells me that "j" is an unknown command. However, for what its worth, I was monitoring constantly with htop the CPU/RAM usage on a separate machine over ssh while running the TuxMath tests. Htop shows all processors by default, and as the instances of TuxMath increased, processor usage climbed on all 8 cores. When the system was max'ed out all 8 cores shows 100% usage. So I assume that TuxMath was at least starting different instances on each core, but I did not know how to look at the individual TuxMath processes and determine which core they were running on. I also don't know if TuxMath is capable of distributing the load of a single process over multiple cores. Does that make sense?

Interesting, maybe this is precisely the problem. Could this be why CPU usage grew with no increased activity? Maybe these dead loops keep the fast system and processors from "catching" up with all the activity and unnecessarily consume the CPU? Where this isn't a problem for a single user, it may be exactly what is causing the problems in a multiuser environment. The application is designed to run at a certain constant speed, no matter the hardware, thus it's reluctance to scale? If this is the case, could this be a setting in a conf file, or read from instances of current TuxMath processes running? Maybe then it could optimize itself for x amount of users then. Thoughts?

I did not, but Robert gave me some info on ibmonitor and I now have that ready. I will download the newest build of TuxMath hopefully tomorrow, then try the same test again with both htop and ibmonitor running. With ibmonitor I can see exactly how much data is transmitted through all six nics. I'll post back.

XP Pro is not a good choice for being a terminal server for windows. It has a maximum connection limit of 4 clients. If it detectes the fifth client, it will disconnect the first and keep rolling through clients like that. Once it decides too many terminals are trying to connect, it turns off the terminal connection service. When you reboot you are resetting the terminal counting process. If you are going to have more than 4 client total, connecting to a windows machine, it must be a windows server machine with Microsoft Terminal Services and an appropriate number of client licenses. > > Fajar Adianto. > > -- > This message has been scanned for viruses and > dangerous content by MailScanner, and is > believed to be clean. > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -- James P.

I hope this is not a general case issue as the inclusion of multicore and thread support should make it _more_ suitable, not less for the lTSP configuration.

If anyone has upgraded an XP machine to SP2 (if you haven't, I know where a bunch of spam is coming from), dig up the license you "agreed" to and reread it very carefully. Buried about 2/3 into it is a blurb about a maximum number of remote connections allowed. I'm a hard-line staunch advocate of Open Source, GNU Public License, Linux freedom. It is imperative that ANYONE who wants to see more FLOSS put into use in schools be also hard-line about being fully paid up on all required licenses - ESPECIALLY MICROSOFT, ADOBE, APPLE, and all of the other educational software. That way we can keep the playing field level and the lawyers out of the schools. Don't go grabbing some cool hack for Microsoft stuff that lets you do things you _know_ they sell an upgrade license for. That has already been covered in the license "agreement" you were strong-armed into accepting. Be adamant about NOT putting that CD of school software on a second (or 20th) machine when you KNOW there was only one license purchased. This is how we have to play the game - fully above board with no "gotcha's" later.

Someone correct me if I'm wrong. In fact, before the 64 bit version, you used to ship with optimized kernels for AMD and 64 bit etc. The only advantage for 64 bit apps is if one app needs to use a lot of memory (like a DB for instance, or photoshop/GIMP etc.) Since it's protected memory, each user's process should be separate, unlike running one bit app. -------------- next part -------------- A non-text attachment was scrubbed...

I have more trouble on some xp clients that are in a bad section of network(Poor functioning media converters). That is because the "client" software for enterprise edition is really just a flash player that pulls all the info from the server through http. I'm hoping with the new flash plugin I'll see even better performance since my reading counts uses the native flash player, not a wine/crossover player. I'll admit we only have SRC and SRI though, not Read 180 which is apparently a bigger hassle to get going.

I work for a medium sized school district in Northern California, we have been using LTSP for almost one year now. I will say that it has been a bumpy ride and there has been a lot of frustration along the way, we a just at a point where the performance is acceptable but we have a special case where we have to use Citrix to present one windows application called Reading Counts, and the performance still leaves a lot to be desired from that side of it.

As a person who has had the opportunity to "pull the strings" and make the decision to go live with something other than Microsoft, don't waste your time trying to ease them into comfort with the new stuff. Just switch and tell them to catch up. These same nay-sayers will belly-ache about the transition from Win98 to win2K then to WinXP and every change in Office drives them batty. If _TEACHERS_ can't learn themselves, how can they expect to inspire learning in their students? > There's a myth among them that linux is hard to use. For now I still > have to face this problem with XP. Not very often it happens, sometime > once a week, sometime once a day. Ask the folks at Morris Brandon about how hard Linux is to use compared with XP. My favorite story told by Daniel Howard is from the teacher who was complaining about how hard it was going to be to learn this new linux stuff She was siting at machine doing here email. Another person pointed out that she was _already_ using Linux as that what was running on the computer she was on. Teachers already don't get diddly-squat for computer use training so why should the transition to Linux be any different? Fact is, by turning the license fee savings into teacher training, the schools get an opportunity to let the teachers hit the ground running with new, fully functional technology that can be integrated into daily classroom operation immediately. > > Thanks. > > -- > This message has been scanned for viruses and > dangerous content by MailScanner, and is > believed to be clean. > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -- James P.

James Kinney was right on. You *can* get majorly sued if you do that. If you do need all those connections to a Windows box, then you need to purchase Windows Server and the "terminal server" Client Access Licenses (CAL's). Matter of fact, you might bring that fact up to help convince the bosses to go w/ a Linux-based solution (e. g. K12LTSP or Edubuntu). And you're right. "Linux is hard" is a myth. And it's FUD perpetuated by Microsoft and their army of scared MCSE's. --TP _______________________________ Do you GNU ? Microsoft Free since 2003 --the ultimate antivirus protection!

Given that lack of talk about supporting it on anything other than RH/Fedora, SUSE and Ubunu/ debian-edu so I'd given up the idea of running LTSP on Slackware and have been using either K12LTSP or debain-edu's setups for this purpose. However, the LTSP wiki said that Gentoo and Slackware were also planning some sort of support for LTSP 5. I was wondering who was working on the Slackware integration and how that is going. Maybe I could be of some assistance, however limited it might be. -------------- next part -------------- A non-text attachment was scrubbed...

In a nutshell, the problem is that Firefox and OpenOffice try to cache image files in the XServer memory, which is a great idea unless the XServer is running on a thin client without a lot of memory. When the XServer runs out of memory, the client program crashes. I've seen it happen *a lot* with both Firefox and Presenter.

It's a catch-22: To talk to PCMCIA devices, you need the kernel to be already loaded; but to get a kernel, you need to have networking working so you can download one from the kernel. The old wireless floppy had a kernel compiled for a very specific PCMCIA NIC (I forget which one) and it was an old 2.4 kernel I believe. Newer kernels are too big to fit on a floppy. One option is to boot from a CD, which will have enough space to load the kernel and necessary parts for talking to the NIC. Another option is to put this same code onto the laptop's hard drive. I think there are how-to's on the LTSP wiki for doing these. As an aside, a year or so ago, I believe Bristol Wireless had proposed paying a developer to work out some code that would talk to some/most PCMCIA subsystems that would have allowed booting laptops with PCMCIA cards. I haven't heard anything about it for a while, so it may not have gotten off the ground. http://www.bristolwireless.net/wiki/index.php/PCMCIABootGPXE Peter Om Dewa wrote: > Does anyone know how to make k12ltsp (fedora core 6 inside) boot from > floppy with pcmcia network card on an old laptop client? > I have tried with ltsp 3 wireless floppy.img, but it was stopped when > entered running level. > Thanks... > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see > From mblinn at peopleplaces.org Mon Dec 10 13:29:50 2007 From: mblinn at peopleplaces.org (Michael Blinn) Date: Mon, 10 Dec 2007 08:29:50 -0500 Subject: [K12OSN] latest Flash 9,0,115,0 : slow in ltsp In-Reply-To: <1197047391.6439.17.camel@server.ltsp> References: <1197047391.6439.17.camel@server.ltsp> Message-ID: <475D3F4E.8010904@peopleplaces.org> I also seem to have noticed things slowing way down with the flash update - With multiple tabs open the browser will lock for extended (10+ second) periods before rendering a page that has flash on it, even when switching tabs. - This is from a thin client looking at a relatively unloaded (<.3) dual-proc dual-core box with 8GB RAM.

We have set quotas on our network to 300 megs for each user account, and some users have issues where core files will take up the entire space in their account and prevent it from working. We have to continually delete core files in user accounts to get them working again. We suspect it is caused by crashes. Also, unfortunately students use the CTRL-ALT-BACKSPACE key as a preferred means of logging out (it's similar to a force-quit key sequence on a Mac that students were taught.), and I believe this is the main source of these files. We've looked online and haven't heard anything from any other LTSP users with the same issue. I can confirm the issue isn't a hardware problem because we use 10 different LTSP servers across the district with home mounted via NFS/NIS, and these files are created on users logged into any of these servers. It must be a configuration issue. Under our current setup, we use a Terabyte server as the central Home and authentication server, which runs ypserv and contains the home folder. Other servers connect via ypserv and mount the home. The strange issue is, I know that under FC, and our FC6, that the creation of core files is turned off by default under the /etc/profile section: # No core files by default ulimit -S -c 0 > /dev/null 2>&1 We went as far as turning on K12LTSP-LIMITS on, and added the following line under the k12ltsp-limits.sh file: ulimit -S -c 0 > /dev/null 2>&1 Then restarted the server. user accounts: /home/athompson/core.6791 /home/aucoind/core.22328 /home/barrowsc/core.5070 /home/bibersteins/core.24006 /home/bibersteins/core.9923 /home/blakem/core.16903 /home/blakem/core.27395 /home/blakem/core.27747 /home/blakem/core.29009 /home/blakem/core.6063 /home/blakem/core.9060 /home/bottingryan/core.29282 /home/bottingryan/core.7044 /home/boucherc/core.10176 ~~~~~~~~~~~~~~~~~~~~~~~ Alan Owen Assistant to the Director of Information Services Hermon Information Services/Hermon School Department "Using Technology to Empower All Students to Succeed in a Changing World." ~~~~~~~~~~~~~~~~~~~~~~~ From jkinney at localnetsolutions.com Tue Dec 11 16:37:16 2007 From: jkinney at localnetsolutions.com (James P.

I'm not sure how you would troubleshoot it, but may have something to do with the config within your nfs > to serverxyz that the home folders reside on. We have used K12LTSP since version 1 and I've never seen .core files end up in users home folders. Also it's worth checking into to get familiar with quotas. I've found that 300 mb set doesn't neccesarily mean the user is actually being able to dump 300 mb of data into their home folder. I've found this value to be off as much as 50%. In other words having quota set at 300mb like you do if you right click the users folder and do properties on their home folder it may show only 150mb( even though they are maxed to the 300mb you have allocated. I have done the same thing with 'du /home 'the values are way off as well. You may do a traceroute from sitting at a terminal to your ipaddress of your home folder server. See if you have a slow spot in the route. This would be hard to pin down,though. Has any of the users complained of application xyz suddenly closing? This is hard to get accurate feedback on, I know.

The -H makes the limit a hard limit (i.e. cannot be increased). That may not be the issue but I agree with Jim check the current size to see what is is currently and then proceed from there...

Whenever I've done my OO.o upgrades to either 2.2 or 2.3 (using the upstream OO.o packages), I've always used the one that comes bundled with Sun Java. I've never had a problem with Impress or any other OO.o app. This typically has been on K12LTSP 4.2EL (the CentOS 4-based version). Soon this won't be an issue anymore, because soon all of Sun Java will be Free Software and thus included in all distros. Then the "Java trap", of which Brandon's case may be an example (Azureus is another), will finally, truly be exorcised. --TP -------------- next part -------------- An HTML attachment was scrubbed...

The trick for me was just mounting home using the Apple OD homeDirectory attribute as it was, rather than using any symlink magic or overloading homeDirectory with a local /home path. On the LTSP servers, I just: mkdir -p /Network/Servers//Volumes/Users and mounted it from the home server using NFS. Obviously make sure the home directory path in "getent passwd " matches reality in terms of mounted file systems. Also make sure NFS is enabled and allowed for the LTSP box on OS X Server too.

Might try using the OS X administration tools to add the NFS share. Don't know if it does any additional magic other than twiddling /etc/exports and presumably /etc/hosts.allow. Also, if you're only sharing to a single IP and not a whole class C network, the netmask should be 255.255.255.255. Looks to me like it's the export setup on OS X that is not correct, since the server is responding with a "Permission denied". > When issue tail -l /var/log/messages, we see many of these errors: > Dec 13 13:48:18 kernel: audit(1197582498.000:550): avc: denied { search } > for pid=2698 comm="irqbalance" name="net" dev=proc ino=4026531864 > scontext=system_u:system_r:irqbalance_t:s0 > tcontext=system_u:object_r:proc_net_t:s0 tclass=dir irqbalance is only tangentially related here, so I don't _think_ this is relevant. -- Dan Young Multnomah ESD - Technology Services 503-257-1562 From jkinney at localnetsolutions.com Thu Dec 13 23:51:12 2007 From: jkinney at localnetsolutions.com (James P.

Check the BIOS temp screen by running the memtest until it locks, hit the reset button and go to BIOS and check temps. It cool quickly so you will need to work fast. Or get a remote thermometer (one of those infrared ones for the children ears) and you can get spot check of temps at the base of the heat sinks.

It would load and start to run Impress, but after the first couple of slides while running "slideshow" it would die. This was with a DevonIT 8020P terminal with 128MB RAM.

I have been using with enough sucess to known that I will reuse it for the nest time. (I took a pen for my first inventory, OCS for the second one, and never took back a pen !) For me, on windows machine only i must say... 1. Pen is long. It take more time writing the name of the machine, memory and harddrive (the very strict minimum) than to install OCSClient. 2. OCS client collect other useful data, (CPU, MAC Adresse.....) 3. The data are SQL stored... that mean you can do whatever you want just by writing your own query ! 4. You don't have to do it again 6 month later.... And how i have done it. (We couldn't use GPO as alternative software already use them and miss things up !) 1. By batch login script... The batch was to heavy (already 5min to switch on some old computer)... So after 1 day of complaint, i take this solution out. 2. By remote software installation. PSTOOLS allow you to run command on remote windows computers if you are authentified as admin. That how i continued to install. A batch script run, ping IP and try to launch install on powered on computer. A choice allowing me to control thing more deeply. 3. Hence initial installation was done, I just add it to a "install script" that already do some initial installation for me: registry key change... (Num lock for example) Now, i can said that we have 92 computer running and that more than a half is more than 6 year old. As computer name are meaningfull choosen, that allowed me to see where to oldest one are. Useful to change them by spare one. As well to find RAM slot machine for spare ram bank. In a word, yes, it is a bit of work for first run... but not as much as pen. And after, great !! ----- Original Message ----- From: Conrad Lawes To: Support list for open source software in schools.

For the price (free) and feature, I would highly recommend OCSInventory. It supports both Linux and Windows systems and well supported by the community. On Dec 15, 2007 7:01 AM, Micha Silver wrote: I use OCSInventory, and we don't need to "sit down at every station". It installs from a logon script, (or set into an AD group policy) and then over time it starts collecting specs and software for each workstation into a mysql database. You can then do filtering by software. The software inventory part isn't that good: you have to filter by software name (i.e "Office 2003 Professional"), then change the software and filter again. It doesn't give any kind of automatic summary of how many stations with each software package. But it's certainly usable. You can also filter by queries like "RAM<512" etc. Cheers, Micha -----????? ??????----- ???: k12osn-bounces at redhat.com ???

Both hardware and software, so that we can be in compliance with licenses and see where we need to focus more. He didn't want to spend much if any thing on it, so I was hoping to get some suggestions from the group on any ideas for handling this. I read some on OCS, but I'd like to avoid sitting down at every station. At that point I might as well walk around with a notepad and inventory it myself ;-) Thanks for your thoughts.

I'll put out a request for linux developers to make a port, but that is all I can do. It's a very small program. So, it would take a competent linux developer 1 day to make. -johnny ----------------------------------- So he is at least open to distributing his source, and has no problem with any Linux developer helping out. If anyone thinks they might be able to take this on you can download the code here http://www.cs.cmu.edu/~johnny/projects/wii/ and if there are any questions (no documentation I guess with the code) contact Johnny at johnny at cs.cmu.edu.

This can be something like "2nd floor" or "Science classroom". Then when the installer runs on each computer a window pops up asking the user to enter their tag. If you run it from login, users will be surprised. On the other hand, if you prepare the installer with *no* tag, then the window never pops up. And the computers appear in the database with an empty tag (which you can edit by hand afterwards). -- Micha Silver Arava Development Co +972-8-6592270 From cisna-barry at wc235.k12.il.us Wed Dec 19 13:00:21 2007 From: cisna-barry at wc235.k12.il.us (Mr Barry Cisna) Date: Wed, 19 Dec 2007 07:00:21 -0600 (CST) Subject: [K12OSN] OT Computer Hardware/Software Inventory Message-ID: <60416.172.28.8.55.1198069221.squirrel@172.28.8.55> Ray, It seems there is no " all in one" solution for inventorying all your network hardware.

GIMP can easily adjust the color balance of any photograph... Colors => Auto => White Balance You might consider downloading 'Picasa' - it's free from Google. It has some automatic enhancements that are really good. Craig From jkinney at localnetsolutions.com Thu Dec 20 22:58:19 2007 From: jkinney at localnetsolutions.com (James P.

It isn't specifically listed as supported by SANE but works fine with the standard epson backend.

For what I'm doing (4" x 5" negatives to enlarge up to 8" x 10") that's more than enough so I don't mind. When I get to the point of scanning 35mm film and slides, it will matter.

Also I won't be using the scanner, this will be for random teachers and other staff to use, so I don't want to rely on editing to fix the problem. I tried changing the color balances in the scanning software, but still couldn't get it to look very good. So I just need recommendations on scanners that work great by default, with minimal tweaking on the user end. I'm not opposed to spending $300 or so if it means a good scanner, but I just don't want to buy one and have the same problem.

In my looking and experience, I thought the Epson Perfection series might be the best choice. I looked at the V700 and similar models, but was a little scared when I didn't see them in the list of supported scanners with SANE. Thanks for the reassurance.

Your " DHCPOFFER, DHCPDISCOVER" should be on eth0 NOT eth1 as yours is showing. try reversing your cat5 cables into your switch off of the back of your server and your ebox may or may not boot. This is not a correct fix,,though. Your dhcp server is dishing dhcp on the wrong nic( for k12ltsp specs at least). As said, you SHOULD be seeing your dhcp requests on eth0.

I am typing this on an Ebox 2300 as a matter of fact. Post back what bios number your ebox is running . Also the only other option in the ebox bios is the int18 or int19/PXE,and it should boot using either selection.You don't by chance have a second ebox you could borrow from a friend or something to try on your lan? I've never had any hiccups with these at all ( on fc5 and fc6) You will need the sound module which I posted a how to on the k12ltsp wiki. If you get it booting I'll email you the ftp site here were you can download the already compiled sound module that works like a champ on fc5&6.All you'd need to do is drop in the sound modules directory and add an entry in your lts.conf for this client box.You could compile it yourself but why waist time( like i did doing it),,:-) Only thing I can imagine is you may have the latest/greatest bios update on it that has KO'd it,, at least a little:(.

I have used it a few times and works like a champ.Surely not written by me but just thought it worth mentioning. Of course be careful using it as it could easily break things especially if you are installing init files and the likes. Yikes!

Items that require root (administrative) permission may show up in the menu, but that doesn't mean the students can make changes to the system. It's going to ask for an administrative password if they try to make changes to the system; so even though they might have that menu, they don't have root access. I'm sure there is some way to change the menu so that students don't even have those menu items, but I've never worried about it, since they can't do any damage. > > > * Now for the teacher..... > The teacher logs in as who.... ?? > Of course we don't want the teacher to log in to the server as > root.

Most of the recent development of LTSP has been happening on Ubuntu/Edubuntu, in part because Canonical is sponsoring someone to do so (Oliver Grawert) and has been very supportive of LTSP. LTSP 5 is a big step in the direction of making it easier to incorporate LTSP into a distro's repositories, but it's not like other applications--that is, it's much more complicated--and while it's got a ways to go, it's getting there. Warren Togami, who founded the Fedora project and I believe now works for Red Hat, was present at an LTSP hackfest this past fall, but I don't know if there's any formal participation by Fedora in LTSP (yet).

You'll find a lot of good info on the wiki; have a look around. -For the teacher, there is no special login, so just create one; don't use the root account for the teacher. You may want to setup the teacher account with sudo access, as there are somethings that may require root-like access, and you don't want the teacher to login as root. -Use Sabayon for customizing everyone's menus. I don't think it's installed by default, but you should be able to install it via yum (command line) or YumEx (GUI). -AND--and this is arguably the most important part--post any questions to this list.

K12LTSP seemed very polished and things just worked. Edubuntu is great and it's getting better all the time, but there was definitely a learning curve this summer when I switched over. I've ranted on this and the edubuntu list in the past on a few issues, but they have been mostly resolved. I'd like to see LTSP5 on fedora because there is quite a bit of functionality that LTSP4 is missing as well an new things on the horizon like easy to use local apps.

With respect to Edubuntu, this thread emerged earlier this month https://lists.ubuntu.com/archives/edubuntu-users/2007-December/002964.html In summary, I would state that the K12LTSP continues to be profoundly well-configured to provide a positive, out-of-the-box experience for a new user. We have grown accustomed to, and never been let down by, the amazing work of our own superman, Eric Harrison. With the likes of Paul Nelson and the strong supporting cast of the K12OSN list, it is a mature and refined project. The one negative, if you will, is that we all must hope and pray that kryptonite and Eric do not meet. Having watched the evolution of Skolelinux, now debian-edu, I am deeply impressed by the culture that perpetuates this project. There is a mature and accomplished support base on the mailing list, and the culture of development benefits from its adherence to debian packaging policies since it is a CDD. There is not a dependence on a single individual. We *all* could benefit from integrating their LDAP backend and web-based gui to manage users into the K12LTSP. This project, with support from the Norwegian government, has evolved with fat, thin, and thick clients all being seamlessly integrated with an LDAP and NFS server. Edubuntu continues to be full of promise and glory - with the next release. I converted several users simply because of LTSP5 and the fact that 7.10 was the result of the vision of muekow and all the amazing development behind LTSP5. The problem is that Edubuntu does not have Eric Harrison or the packaging policies of Debian, therefore the tweaks required to configure a fresh 7.10 with mixed hardware are absolutely not acceptable for a new user. Whereas Eric and this list keep most from falling through the cracks, and debian-edu makes it a policy to create a distro for the average teacher with only a few available admin hours a week, the final word on the Edubuntu users list was that a newbie will need to buy support from Canonical if they can't figure things out on their own. All this said, I hope that the future State of the K12LTSP is to a. Integrate a sustainable LDAP/NFS/Authentication solution, be it FDS or debian-edu's solution b. Include LTSP5 c. Follow the lead of Skolelinux and create a fedora-edu distro just as they have developed a debian-edu distro. It would, of course, be a shame to once again see the work of debian replicated, not collaborated, but that is what idealism is for. d. Create a culture of development and support that is stronger than any one individual. > > --TP --scott From brcisna at eazylivin.net Fri Dec 28 19:32:37 2007 From: brcisna at eazylivin.net (Barry Cisna) Date: Fri, 28 Dec 2007 13:32:37 -0600 (CST) Subject: [K12OSN] No IP Address Once Message-ID: <45830.192.168.254.3.1198870357.squirrel@www.eazylivin.net> Fajar, What is the make and cpu/ram/nic make, of the client that stumbles one time? Also ,stupid question, Have you tried connecting the client with a different cat5 cable into a different port of the used switch? Some nics get confused on some managed switches ( due to spanning tree,,,yada,,yada,,) that I have read also. Never actually had this happen to me,though, but a possibility as well. Are you using floppies by chance to boot the client? If so try making another floppy image and possibly this may be a resolve. I'm sure you've probably tried all of these:).

Ok Did you try another cat5 wire into a different port of the switch? Next what I'd do is on your k12ltsp server drill down to: tftp/lts//boot/bootroms/ There is a universal boot floppy image contained here. You build it very much the same as you did your rom- o - matic floppy image. View the readme.txt file here on how to create a "universal boot floppy image." The ebnet522.dsk/universal boot floppy image is in the same directory as the readme. Build it as described in the readme,then,>Boot your HP with this,>This will automagically identify your 3com nic. I wonder if possibly you may just need to play with different irq/dma,,,blah,,blah,,stuff for your HP machine. Older HP's has weird stuff built into their bios's as far as irq sharing,etc. FYI: At rom-o-matic as I recall there are about 10-12 possibilities with different pararamters( for the 3c905) you can build. This uni boot image will streamline this for you:-) Quit possibly you will get better results with this uni boot image with this particular machine,:-) Let us know your progress. Keep scratching!

If that is the case you could simply set it up as you are wanting and just default,say by MAC address( whichever machine(s), or all machines) to come up to the the '03sbs server at bootup by placing your comments in the lts.conf file for this, if that is what their "first" choice is. Then, do an CTL-ALT-F2 and drop into the *good* k12ltsp desktop. With this approach the " naysayers" can't be so skeptical as most unknowing linux people are. Sidenote: if dhcp is a gotcha change the k12ltsp server to dish dhcp to "certain clients" by changing the listening port to port 1067 then they can run dual dhcp on the same subnet. I do this in a couple of our school buildings. The only thing with this approach you have to remember this. It could cause you lots of head scratching if one or the other servers shuts off, say over the weekend or whatever:-). Also if you use the changing to port 1067 you'd have to reflash whichever PXE boot machines to run pxe on port 1067 which is not a biggy. As a test enviornment you could make it very easy with floppys,but surely isn't as clean as pxe boot machines. Maybe I misunderstood your question too.Another approach as well would be if all of these machines are existing with HD's in them do the eb_to_hd ( Etherboot to HD),and add your bootup to whichever server you like as well.

On our K12LTSP 5EL server the files under /tftpboot/lts/pxe belong to the ltsp_i386-boot package. If the ltsp_i386-boot package in the yum repository is updated, then yum will pull it in when you run yum update. The ltsp_i386-boot package seems to be maintained by Eric Harrison ("the K12LTSP guy"), so you might want to ask him about updating the package. Nils Breunese.

Yum should update to the latest version of the files that were built for the distribution version you installed (there have been many k12ltsp distribution versions based on both fedora and centos). If you want the latest, you have to install the latest version of the distribution. But for an easier solution, if the laptop is capable of booting itself, why not just run vnc, the NX client against freenx on the server, or X in '-query server' mode when you want to be a client to the k12ltsp server. These give pretty much the same functionality plus better use of local resources if you want them and are cross-platform so it wouldn't matter if the laptop booted windows or linux itself. My preference from those choices would be to boot the windows that probably came pre-installed on the laptop and run the free NX client that you can download from http://www.nomachine.com with freenx on the k12ltsp server. There is a small amount of setup to make this work (you have to copy over an ssh key) but it only has to be done once and freenx has some advantages in performance and being able to re-connect to suspended/running sessions. -- Les Mikesell lesmikesell at gmail.com From toddobryan at gmail.com Sun Dec 30 21:16:48 2007 From: toddobryan at gmail.com (Todd O'Bryan) Date: Sun, 30 Dec 2007 16:16:48 -0500 Subject: [K12OSN] Updating the PXE start files In-Reply-To: <4777CB70.3010103@nudata.fi> References: <4777CB70.3010103@nudata.fi> Message-ID: <904774730712301316o2fce86adl80ad2db9b54364df@mail.gmail.com> On Dec 30, 2007 11:46 AM, Kenneth Lundstr?m wrote: > My client got an new Thinkpad R61 and would like to use it mostly as an > client in the LTSP network.

The installer script automatically installed winbind, but I'm not sure I really need it. Is winbind's only purpose to authenticate a Linux machine against a Windows domain controller? (If so, then I don't need winbind). I removed winbind and my setup still seems to work, but I'm afraid that my testing might be insufficient. Any advice is welcome. -Rob From dhuckaby at paasda.org Mon Dec 31 17:32:47 2007 From: dhuckaby at paasda.org (Huck) Date: Mon, 31 Dec 2007 09:32:47 -0800 Subject: [K12OSN] [Highly OT] Terminal service with win2003 server In-Reply-To: <774593a20712281832u6bca49bewe5f198fb8fce834d@mail.gmail.com> References: <774593a20712281832u6bca49bewe5f198fb8fce834d@mail.gmail.com> Message-ID: <477927BF.3090703@paasda.org> Sudev, Many commercial thin clients are setup to do just that... they have some wanky windows CE or something similar that they boot from and can attach to a windows client server... I personally have never used one as such because I have ZERO windows servers at any of my LTSP install sites. And don't want to spend the time configuring and hardening one just to test out my thin clients ability to do such. But know that it is possible, with commercial clients. --Huck Sudev Barar wrote: > I am trying to convince some people to move to linux+ltsp setup. > However they want to try comparative setup under win2003sbs server.

Since windows domains can exist that are not internet capable, they need a way to resolve a machine name to an IP address for a share access. Linux as a samba server with winbind works quite well (within the limits of the winbind design_. If you need it, you will know because suddenly windows desktops will not be able to browse the windows network for machines with shares.
