This houses details data about everything hardware (and kernel-wise) on the system. ioports has all of the ports, interrrupts has all the interrupts. They are all text "files" that can be "read" using "less /proc/ioports" , etc. Another useful command is /sbin/lspci . It will tell what is plugged into the pci sockets on the motherboard. Its sister command /sbin/lsusb does the same for the USB bus. A cautionary note: most places in /proc are read only. A few are run-time kernel variables that if set improperly will cause strange things to happen. If those need to be set, the place to do it in /etc/sysctl.

(Or maybe using the gui for yum - yumex). From the gui with the inserted CD, there isn't much to do other than run the mouse over the text, highlight it and then middle-click to paste it into an open text editor (gedit is pretty basic but functional - Applications->Accessories->Text Editor if you use Gnome). If you are upgrading with yum at the command line, you have some more flexibility. yum deplist package1 [package2] ... > mydeplist.txt will write the needed files for the listed packages to the new file mydeplist.txt in the current directory. If you are upgrading/installing a package with yum, it will grab the needed dependencies for automatically. The only times I have seen is fail in that is when the original packed is not packaged correctly or the mirror I'm pulling from hasn't finished _it's_ update and the new package is available yet. So I usually wait an hour or so and try again. Sometimes, I have a conflict with something I built. I can exclude the conflicting package with the --exclude= added to the yum command. > > Les Mikesell wrote: > > On Sat, 2006-09-30 at 15:39, John P.

I recall that there were some patches to set the default save to .doc but it applied to only OOo2.0 and you needed to find the directory that had openoffice.conf.

Each answer will be, obviously, worded slightly differently, and as such, one of those answers may be the 'magic' one that makes the most sense to the person who posted the question. Since the archive of the list serves as after-the-fact documentation, multiple answers help make that documentation more complete. Sometimes the first answer is short and simple and accurate, while a subsequent answer is more complete, but slightly inaccurate, which inspires another response correcting the previous mistake, or inspiring yet further discussion. All of this provides a much greater explanation and solution to the problem at hand. So, don't be afraid to try to help!

This means that you can run vncserver on your machine even if the video card itself doesn't work correctly, the only thing that it requires is that you have a nicely formed Xorg config file. In case your video/monitor blows out, it is a nice way to be able to run your GUI scripts and programs until you can get a replacement.

I will cover the use of Linux, Open Office, and many other programs that can be used by K-12 schools to decrease their software licensing costs, provide stable computing solutions, and introduce students to collaborative programming. I run the Open Source labs for the CUE.org and NECC ed tech shows, am currently working on a book for ISTE on this topic, and have a weekly web radio show on educational technology at EdTechLive.com. I'm looking for other school or district venues where you think this topic would be well-received, and to see if I might be able to demonstrate enough interest to find a sponsor for a more national tour.

Anyone have any magic? Memtest won't fix damaged RAM. (Boy would THAT be nice!). You may have a scrambled disk but I doubt it. Since the system will boot OK if you slow it down and go manually, I suspect the RAM is bad (or a bus chip is damaged) and running it at full speed (i.e. let it try and load by it self) may be overheating the problem area causing intermittent failures. Memtest will tell you if the RAM is toast(ed). It the memtest is OK check the heat sink on the CPU and make sure it is solid and feels warm and that the cpu fan is spinning freely (I have cats and dogs so I have fur-lined heat sinks and fans that choke on the stuff). The fsck may have only checked a tiny /boot partition. This is the time for a good boot floppy or bootable CD. Run fdisk -l to see what partitions you have and then run fsck on all but the swap partition. You can always rerun mkswap to reformat the swap space. badblocks is another good tool to run. It can find and record the location of, well, bad blocks on the hard drive and mark them as such so they won't get used. If you want to get under the hood and really tinker with the RAM http://rick.vanrein.org/linux/badram/download.html has a kernel patch that allows the use of moderately damaged RAM in a working system. > > Thanks, > > Barry Cisna > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -- James P.

Is > Realtek OK? The issue with wireless networking cards is they require some kernel level stuff to initialize the card. Thus, they can't be used for the boot process. LTSP can be used if a small boot kernel is on the system that can drive the card and then the system just gets it's X-windows stuff over the network (a fatter client than diskless, no OS using PXE boot). So far, every RealTek networking device I have seen work with Linux. They usually don't perform above average but the work. Note: Wireless bandwidth is limited. LTSP can be bandwidth intensive.

I had hoped to have it done last weekend, so it should be ready sometime real-soon-now ;-) As for K12LTSP 6.0, the "muekow" packages will not be production-ready. It will use the "classic" LTSP packages by default. The basic infrastructure for "muekow" is already in FC6, so early adopters will be able to test it out and we can polish up to make it the default in FC7. -Eric David Trask wrote: > "Support list for open source software in schools." > writes: >> Hey all, >> >> I know this might be VERY premature, but is anyone looking forward to FC6 >> and the possibilities with K12LTSP?

At least that last command is not a valid command. You specify which repository to enable when using the --enablerepo switch.

You seem to have mixed up some thing. The file should have a .repo extension (not .d) and it should be located in the directory /etc/ yum.repos.d/.

For those who missed the previous posts about this, the "missing text" problem is a known and common bug with Flash in Fedora, and should be fixed internally in the upcoming version 9. My research found this: http://macromedia.mplug.org/faq.html specifically #11: Fedora Specific Information ------------------------ 11. Most text is failing to display on Flash sites! The plugin has bugs where it makes bad assumptions about the font configuration. For this reason, it fails to find fonts on newer versions of X.org. You can workaround this problem in the short-term by using these commands as root. mkdir -p /usr/X11R6/lib/X11/fs/ ln -s /etc/X11/fs/config /usr/X11R6/lib/X11/fs/config Read Red Hat Bugzilla #184028 for more information about this problem. Adobe should be fixing this in Flash version 9 for Linux. and here's the subsequent link: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=184028 it now displays fine and all is well! ---- Eric Harrison wrote: > Jim Kathan wrote: > > I'm using K12LTSP; Our school is using a web-based student reading > > program (Renaissance Learning Accelerated Reader) in Firefox.

From mblinn at peopleplaces.org Wed Oct 4 13:41:27 2006 From: mblinn at peopleplaces.org (Michael Blinn) Date: Wed, 04 Oct 2006 09:41:27 -0400 Subject: [K12OSN] LDAP authentication Message-ID: <4523BA07.9040504@peopleplaces.org> I recently ran into some troubles with LDAP authentication that brought my server to its knees. While I am sure that a more experienced sysadmin could have avoided or sidestepped these problems, my actions exacerbated the situation. I have 4 NICs in my server. I took it to another subnet and unplugged the 'main' links. Upon doing so, slapd complained that it would not bind to the new address, or even to the localhost interface. As such, all authentication ground to a halt, and I had to do a forced (untidy) shutdown. This forced shutdown caused filesystem corruption that my knowledge of e2fsck could not rectify (server would lock on 'INIT: booting init 2.63' even after e2fsck reported no errors). The real stinker came when booting with a rescue CD. Even in this process, each command issued in init level 1 (singleuser) would cause an authentication to be attempted on the LDAP server, which looked like a lockup, as the default is to retry after 4 seconds, then 8, then 16, then 32 and finally 64. 124 seconds is a LONG time to wait for each command to complete when attempting to rescue a system. I'm sure that I could have authconfig'd from the command line, however the long chain of fixing filesystem errors while waiting 124 seconds for every command to complete just so I could mount a volume and do the authconfig just so I could find the ldap database corruption error was one that I realized about halfway through that I did not need to put myself through. For this reason, I am back to simple shadow authentication with a separate samba database of users. The only benefit which I could see to using LDAP for Samba and system authentication was that I did not have to perform each add/edit/delete operation twice when making user changes. I'm sure that others have more compelling reasons to use LDAP for system-level authentication however I don't believe that something as inherently basic to the operation of the server should be handed to a daemon-level tool. Comments are welcome - I'm hoping to learn something more from this exercise, so please correct me where I am in error, and suggest what I could have done differently. -Michael -- If this is my day of harvest, in what fields have I sowed the seed, and in what unremembered seasons? - Kahlil Gibran CONFIDENTIALITY NOTICE: This message, and any attachments that may accompany it, contain information that is intended for the use of the individual or entity to which it is addressed and may contain information that is privileged, confidential, or otherwise exempt from disclosure under applicable law.

If there is How do > I do it? Here is what I am gearing up to do along this same line: Scenario: Up to 200 thin clients attached to a single server. Each classroom has a networked printer that cups on the server knows about. Students have NIS/NFS roving profiles since they move around the school (middle school). During the login process, a script is run that determines the host name (all fixed-IP host name in dhcp.conf) that the student is accessing the server from. Host names are based on room number and station number: rmXXXwsYY where XXX is the room number and YY is the station number in the room. Printers are named similarly: rmXXXlaser At the moment, I am determining the best place to put the script (~/.xinitrc , ~/.bashrc , ~/.xsession , ... ) . Here is the script: #!/bin/sh # This script will identify the host name from which a login occurs # It will then use that name to set the default printer # This requires hostname formatted as rmXXXwsYY and pinters as rmXXXlaser # XXX is the room number and YY is the station number in the room. # the script runs as the user logging in and sets options in ~/.lpoptions export PATH="/bin:/usr/bin" lpoptions -d `netstat -t -e | grep ESTABLISHED | grep $USER | sed 's/:/ /g'| awk '{print $6}' | sort | uniq | cut -f 1 -d "." | sed 's/ws \w*/laser/'` # Place this script in /usr/local/bin/defaultprinter.sh on the server with 755 permisions NOTE: the lpoptions line is one line. email will wrap it. Part 2: Blocking printing to a printer not in the same room with the student: In cups, each printer should allow printing only from a given range of IP address. That is done with per printer settings in cupsd.conf. HOWEVER, I don't have this part working yet as the print job originates on the server and not the client. I am looking pykota/tea4cups as a possible way to rewrite the source address on the print job. > > Thanks in advance > Pat > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -- James P.

However, the thin client environment has the print job coming from the IP address of the server hosting the boot up and apps, not from the client itself. Printing by user authentication is not an option either as roving students would require restarting cups for each login operation. > ---------------------------------------------------------------------- > Steven Santos > Director, Simply Circus, Inc. > Email: Steven at SimplyCircus.com > Mail: PO BOX 620753 > Newton, MA 02462 > Phone: 781-799-4938 > eFax: 309-214-0899 > Web: www.SimplyCircus.com > > > -----Original Message----- > > From: k12osn-bounces at redhat.com [mailto:k12osn-bounces at redhat.com]On > > Behalf Of James P.

I tried getting this model to work with sane, and have been unsuccessful so far. There _is_ source code available, but it apparently hasn't been updated for a while, and even after I successfully compiled it I couldn't get the scanner to work (it works fine with Windows, so I know the scanner's not broken).

The machines are all Pentium 3's running Windows 2000, with 128MB RAM. The latest anti-virus package, imposed by our parent company, is causing these machines to slow down so much that they are borderline unusable. One thought I had was to set up an LTSP server that uses VMware or Qemu to run Windows 2000 on Linux. (I have enough Windows licenses to cover all the potential users). Would this work? Would my server load running 10 instances of virtualized Win2k be 10x the load of running just one? Or would I benefit from the sharing of memory, processes, etc? Would I need to load 10 separate Windows images on the server, or just one? Another possibility is booting off an LTSP server and using that to initiate a session on our existing Windows Terminal Server. This will require that we buy more licenses ($75/user, I'm told), and may or may not require a hardware upgrade to the server. The most boring option is to buy new desktop machines w/ no OS and install Win2k on them using our existing licenses. (The old desktop machines will be decomissioned). I'd really like to expose the users to Linux, and that makes this option even less appealing to me. So, what does everybody think? Any other ideas?

I'm currently running VMware (much faster and easier than Qemu/kQemu) on a Ubuntu machine. I can tell you right now that you will NOT benefit from the sharing of processes; you can benefit SOME from the sharing of memory (although it's a speed tradeoff); and you would, in fact, need to load 10 separate Windows images on the server. This is probably not a cost-effective solution for you, because these virtualization / emulation solutions pretend to be an ENTIRE PC, right down to the hardware level. To adequately run 10 copies of Win2k on a server, let's say at 256MB of memory per virtual machine, you'd need about 3 GB of RAM. Add in the further requirements for the LTSP side (including the thin clients) plus all the private networking traffic, and a hard drive image for each virtual machine and you're talking about a sizeable server investment. I have no experience with the Windows Terminal Server end, but I understand it's pretty easy to accomplish; since an LTSP server to support only 10 users is fairly cheap to build, this may actually be the most cost-effective option.

Thanks for the info. When you say VMware is faster/easier, did you mean faster to set up, or that it runs faster? -Rob __________________________________________________ Do You Yahoo!? Tired of spam?

You can use both approaches if you want. That is, install Window2003 server under vmware (on your k12ltsp server or elsewhere), run one instance of it and connect to it from ltsp-booted thin clients running rdesktop. -- Les Mikesell les at futuresource.com From scott at hosef.org Wed Oct 4 23:23:15 2006 From: scott at hosef.org (R.

We use SMBLDAP to authenticate student logins on the server. The guy who helped me set it up sent me some directions; the first thing it tells me to do is mv /home/administrator /administrator and then usermod -d /administrator. We make "admin" a local login and administrator a server login. When I do this, I can no longer run anything, particularly the users & groups GUI or the Synaptic Package Manager. My question is, is there a way to make these things run without the existence of the /home/administrator directory? Any other ideas for ways to make these Edubuntu workstation logins authenticate on teh server? Any ideas for speeding up the computers that authenticate really slowly? I need to set up 2 workstations that puked on me; I also have a couple of workstations that take 3+ minutes to log a student in. The other workstations log people in in under 30 sec's.

I think I have two lingering questions. Squidguard is on Port 3128 and dansguardian is on 8080. I have found that when I manually set the browsers to 3128, squidguard does not come in to play. Can I just set the firewall rules to 8080? Where do I put these additional rules so that they are loaded on each reboot?

You use the Client Customization Kit to create an .xpi extension. http://www.mozilla.org/projects/cck/firefox/ One way to install it globally: http://www.mozilla.org/projects/cck/firefox/faqs.html Probably have to do that as root.

Hi there, I'm not sure if this helps, but I noticed that once we upgraded all of our servers to kernel-smp-2.6.17-1.2187_FC5, X failed to launch on ALL of our servers, even with different hardware.

What it would take is a script that gets run (as root) for each login that finds the user name in the /etc/cups/cups.conf file, removes it and puts it in the correct group and then sends a SIGHUP to cups. However, a SIGHUP has the potential of breaking a print job if it happens at some critical points. > ---------------------------------------------------------------------- > Steven Santos > Director, Simply Circus, Inc. > Email: Steven at SimplyCircus.com > Mail: PO BOX 620753 > Newton, MA 02462 > Phone: 781-799-4938 > eFax: 309-214-0899 > Web: www.SimplyCircus.com > > > -----Original Message----- > > From: k12osn-bounces at redhat.com [mailto:k12osn-bounces at redhat.com]On > > Behalf Of James P.

I wish my memory was better, but I had the same problem (worked the first few times I accessed it and then a little later an X when I tried, rebooted and problem was temporarily gone) last time I did a demo of how rdesktop could work on another screen. I think the fix was an extra switch in the rdesktop command, but I can't remember for sure. I'll bet if you restart your server it will work for a short period of time again (quick fix). If not, search around for more switches to add to the command. -- This message has been scanned for viruses and dangerous content by the Cotter Technology Department, and is believed to be clean.

I think it was something with the SCREEN order. I think my fix was ultimately making SCREEN_01 the term server, and SCREEN_02 the RDP server. Something about X not firing in the right order or something...still cloudy but maybe in another 10 minutes more will be there :-) Anyhow, I know it is less than desirable but try and change the order. I think it was that rdesktop might have been trying to connect right away, but since it was on screen 2, X was being prepared for it fast enough. The more I think about it that doesn't make sense, but I think it was something with the order, or at least that was my quick fix for demo purposes.

Eric said to change a line in the /etc/X11/gdm/gdm.conf file that was supposed to make X not start on the server, but I cannot find that line in the gdm.conf file on this server. 0=/usr/bin/X11/X,#0=/usr/bin/X11/X Is there some other way to do this?

Message-ID: <20061006150036.27500.qmail@web31603.mail.mud.yahoo.com> hi everyone! We have a few K12LTSP servers at our school, each running the version based on FC5. We've also used the smbldap-installer to setup centralized user management, which has been working pretty well. Here's an overview of our server setup: server A => 1 NIC, configured as PDC (on the school's main internal network/subnet) server B => 2 NIC, configured as BDC server C => 2 NIC, configured as LDAP Client (and NOT as a BDC) All three servers have a NIC on the main subnet. And all are running thin clients on their respective subnets. For those Windows PCs connected to the main subnet, they're authenticating okay against the domain. Servers B and C are classroom thin client servers, whereas server A handles the rest of the campus (definitely not large). I've recently added a Windows 2000 PC to the subnet run by server C. This PC used to be on the main subnet, and while there domain logins worked perfectly. However, now that it's on the subnet run by server C, it is unable to authenticate to the domain, but I do want it to be able to do that. Does anyone have ideas on what I should do, or can at least point me to relevant information on the Internet? Do I simply need to change server C to be a second BDC? Thanks in advance!

I had to manually hack mine (4.2.3EL) because when I would run a shell on the client, the rdesktop command line (under ps) showed an extra "-U" and it would not start rdesktop. I rewrote the wrapper (to not take a parameter from the other script that calls it, so that may be where the problem really lies) and it connects now.

When you run rdesktop as a screen on the terminal, it is the *terminal* making the connection directly. The terminal is just like any other computer in the sense that it has its own IP address, is on its own subnet, etc. So, when the terminal needs to connect to another subnet, it has to be routed there by the server. Here's how to enable this: In dhcpd.conf: option routers 192.168.0.254; In /etc/sysctl.conf: net/ipv4/ip_forward=1 Enable NAT from commandline (or this may be a service in K12LTSP): iptables -t nat -A POSTROUTING -j MASQUEARADE -o eth1 (or service nat restart) Make sure ip_forward is on: echo "1" > /proc/sys/net/ipv4/ip_forward Reboot the terminal.

Thanks! Implementing something more automated with samba/dhcpd/??? settings would be nice, if only for future reference, but for the moment: a) this is just for one Windows PC b) for this particular PC and what we're using it for (mainly Rosetta Stone), if I can't get it to authenticate to the domain, it's not a big deal I usually check the various documentation on samba.org, especially "Samba by Example" (I think that's the name).

It locked up the server, but it wasn't a complete hard-lock. I have to manually kill the processes to get it to let go. There may just be some ghoulies on this thing and I may just have to do another install on it to get it working right. . . This is a live server and I don;t have time to work out problems with upgrading to a newer K12LTSP so I really need to stick with FC3 for now on it. If I update to a later version of K12LTSP, what impact will that have with my samba (primary functions of this server, K12LTSP is a sideline on it). In the past, I have jut copied my config files and account-related files and it was just a bit of tweaking to do then everything works. If I go to a new version of K12LTSP, will my current samba configs work with it? Thanks!

That seems odd; the home directory shouldn't have anything to do with this. (So the answer to your question is "yes, by doing just what you've described.") Keep in mind that if you're running Samba/LDAP you probably don't want to use the Users & Groups GUI anyway, because it can't help you with your LDAP users. Is it still possible for you to run the 'sudo su -' command and become root? > Yeah....as root. Just be careful. Hmm. Not to be contrarian, but you can only run the GUI apps as root if you do one of the following: 1) enable a graphical root login, which is definitely more trouble than it's worth 2) enable TCP connections to an Xserver, enable a remote host to connect to your X session (xhost), and set DISPLAY= when you run the GUI apps from the command line as root 3) enable root logins via ssh and ssh -X into your box and then run the GUI apps from the command line Of those options, the best by far is #3, which requires only that you set a root password ('sudo passwd'), ssh -X root at localhost, and then run 'synaptic' or whatever else. But it would be preferable for you just to 'sudo synaptic' instead, in which case you should just be able to run it from the menu like usual...and since you can't do that, I wonder how far you'll be able to get with any of the rest of this. > >Any other ideas for ways to make these Edubuntu workstation logins > >authenticate on teh server?

LDAP is the best of the available alternatives, and with the caveat that I know the author personally and am therefore biased, I must say that the Samba/LDAP installer makes it pretty easy to set up LDAP, even if you don't care about Samba. Your authentication times do not sound at all happy; especially if this is a small number of workstations in a single room with the server right there, we should be talking about something <10 seconds for the actual authentication part. Just to double-check, it sounds like you're talking about regular fat clients and an Ubuntu Samba/LDAP and file server, right? --matt -- Open Source Software Engineering Consultant http://majen.net/ -------------- next part -------------- A non-text attachment was scrubbed...

I'm on the newly-formed school tech planning committee in my community, and at the second committee meeting I discussed the idea that there's a tipping-point at which access to technology naturally snowballs into increasing technology integration. (There's a bit of the "if you build it they will come" thinking in here.) I asserted that I believed studies had been done on such data points as the range of student:computer ratios that define such a tipping-point. The committee chairman (a school board member) insightfully asked if I could find out about such studies and report back at our next meeting -- so now I'm asking all of you. I've done some googling and I'll do some more, but what studies (formal and informal, but I'm looking for more than just opinions) do you know of that communicate concrete results such as (NOTE: I'M MAKING THIS UP as an EXAMPLE!): "Moving from a 10:1 student:computer ratio to a 2:1 ratio is 75% more likely to result in a 20% increase in math standardized test scores than moving instead to a 5:1 ratio." A study with results like that would be outstanding, of course, but I'll be pleasantly shocked to find one. What has actually been done? What more do we have than anecdotal evidence of the sort of tipping-point that I described? I'm pretty sure I snagged the phrase "tipping point" directly from one of the slides in Daniel Howard's presentation to the CIO of Atlanta Public Schools on their case study at Morris Brandon Elementary School. Here's what he said: Tipping point: must have at least 5 PCs for teachers to fully integrate into instruction, more is better for most teachers I'll follow up with Daniel to find out how many students those 5 (LTSP) PCs are covering...but what have the rest of you experienced in your own schools? With 1:1 as the assumed goal, what ratio will give us the best bang-for-the-buck along the way? --matt -- Open Source Software Engineering Consultant http://majen.net/ -------------- next part -------------- A non-text attachment was scrubbed...

I tried entering a DNS zone for my domain in BIND with the internal number of the server, but, when i do a < host server,,, ip address is:> , it throws out the public ipaddress,and i think this needs to end up being my private ip, so on my home lan my server sees itself as the dns server. I have entered both 127.0.0.1 in the dns record in network as well as [ private ipaddress]primary/secondary and thought this would make this server see internal IP. No joy:(.

If you are connecting from the internet and get your routers gui then anyone else can too. Unless you need to remote admin the router from the outside, it is probably best to disable router admin from the WAN side. Also, check to see that your http port is forwarding WAN request to the server, and not letting it sit on the modem/router. Not sure if this helps, but it sounds like either a router configuration or if dns is done internally by FC5 then there is a configuration issue that is looping back to your routers admin page.

Message-ID: <000001c6eb4c$315cb940$4000a8c0@themm> My school uses HP Procurve switches that give all sorts of CRC alignment errors if they are not set to automatic uplink/downlink connection speed (10/100, etc.), and if flow control is set to anything other than off/disabled. Interestingly enough, these picky switches also want whatever's connected on the other end (NIC card, jet-direct printer, etc.) to be set the exact same way, or you also get errors. I noticed one of my MS-Windows server's nic card was set to 10/100 (not automatic link) and flow control was not turned off. So it gave me tons of errors with the switch. Getting to the point; I was wondering if there are any configurations/customizations/tweaks that I can do for my NIC cards within K12/Fedora? I am wondering how they are set be default, and what I can change. I looked around but didn't see much of anything. I know K12 is designed for most situations to work "out of the box", but my situation warrants further optimizing for the NIC, if it's possible. Thank you for reading this and any help given.

I also run authconfig on the remote machines and choose ldap as the authentification. I would guess that SME would allow the same.

I also use Procurve switches - great bang for the buck! The behavior you described is not specific to Procurve only - that's how all switches behave. If you do not have the ports set to auto-negotiate, you must configure the NIC on the other end of the cable with the same settings as the switch. If you do not configure the NIC, it will automatically default to 10Mb half-duplex - the lowest common denominator. And then watch the errors fly! > Getting to the point; I was wondering if there are any > configurations/customizations/tweaks that I can do for my NIC cards > within K12/Fedora?

I know > K12 is designed for most situations to work ?out of the box?, but my > situation warrants further optimizing for the NIC, if it?s possible. I believe the default NIC setting is also auto. To make life easy, I would set the ports on the switch to auto then allow the NICs to auto-negotiate the connection. (I only stray from this is very special circumstances.)

I did the same thing you mentioned, setup a DNS zone on the DNS/DHCP/Samba server I installed in the office. That zone would provide a local (192.168.x.x) address for the company domain name. Since the DNS service was only for internal use, it worked fine. If the 'host' command returns the public address, then verify that it is querying its own DNS service and not, say, that of the ISP. I think the syntax is something like host name-to-lookup server-to-query server-to-query is an option which you don't normally have to specify unless you want to query a specific DNS server, which you do in this case.

The method I used probably breaks a lot of stuff, but it works well for me. Here's what I did (critique welcomed): 1. Switch to KDM (I like login & password boxes both on the screen). To do this, add an entry in /etc/sysconfig/desktop that reads: DISPLAYMANAGER="KDE" 2. mv /etc/X11/xinit/Xsession /etc/X11/xinit/Xsession.original 3. create a new /etc/X11/xinit/Xsession with the following lines: #!/bin/bash . /etc/X11/xinit/xinitrc-common exec nautilus -n & exec /usr/bin/icewm 4. make it executable (chmod +x /etc/X11/xinit/Xsession) I think that was it... It disables EVERYTHING else, even though other options are listed (like Gnome, etc). Regardless of what you choose, you get icewm.

Assuming you've done all that, on the Linux box you just run 'mount host:name-of-export /mountpoint' where mountpoint is the empty directory where you want to access the files. A little more detail in your question as to what you're trying to do would be helpful. NFS isn't really a file system type, so much as a method for sharing a file system with other computers. As such, there is no such thing as a 'NFS drive partition', on XP or otherwise.

It will be NTFS. Now, depending on the kernel version and whether or not the NTFS support is in there, here is one way to do it. Logged in on the linux computer as root: make a directory - example mkdir /cdrive then mount that directory like this or similar: mount -t ntfs /dev/hda1 /cdrive the /dev/hda1 will depend on the partition your ntfs filesystem is in. One way to do that id to run fdisk and look at partitions. fdisk /dev/hda the first IDE hard drive fdisk /dev/hdb the second IDE hard drive and so on. So, if fdisk you'll see the partitions listed like: Disk /dev/sda: 219.8 GB, 219823472640 bytes 255 heads, 63 sectors/track, 26725 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 4 32098+ de Dell Utility /dev/sda2 * 5 69 522112+ 83 Linux /dev/sda3 70 9207 73400985 83 Linux /dev/sda4 9208 26725 140713335 f W95 Ext'd (LBA) /dev/sda5 9208 18345 73400953+ 83 Linux /dev/sda6 18346 22522 33551721 83 Linux /dev/sda7 22523 23827 10482381 83 Linux /dev/sda8 23828 24871 8385898+ 82 Linux swap /dev/sda9 24872 26725 14892223+ 83 Linux In my case the drives are SCSI, so they're listed as sda instead of hda. So say your windows was on /dev/sda4 as in the above example. Your mount line would look like: mount -t ntfs /dev/sda4 /cdrive Now, again, depending on your kernel and what support you have, you should be able to read that partition, but likely not write to it.

I got several responses from Eric and several others and tried their recommendations to no avail. One was to edit the gdm.conf file and comment a line that made X not start on the server but would allow the clients to run it. That did make the server run ok, all the way to runlevel 5 without starting X on the server. But the workstations still lock X up, usually when you try to logout as a user. I am going to try to go back a few more kernels and see wht happens since some of the responses were kernel version related. I have had similar problems in the past but always with smp kernels and when changing back to the regular one, it was resolved. Not this time. . . Any other ideas short of another re-install? Thanks!

"rpm -V packagename" will check every file owned by that package and make sure that the file integrity, ownership, permissions, date stamps, etc all the same as when the package was installed. It will also make sure that all of the dependencies for that package have been met. While "rpm -V package" verifies that a package's dependencies have been met, it does not verify the dependent packages themselves. (note: "rpm -Va" will verify all packages). Try running these commands to verify all of gnome-games' dependencies: rpm -V cairo glib2 gtk2 libart_lgpl libbonobo libbonoboui libglade2 rpm -V libgnomecanvas libgnomeui libICE librsvg2 libSM libxml2 pango If that all checks out, the only other thing that comes to mind is if somehow your file system is mislabled and SELinux is causing you problems. Try running "setenforce 0" and try starting one of the games that are giving you problems. If that works, run "restorecon -R -v /" to relabel your file system. -Eric From fhkms at adelphia.net Wed Oct 11 12:28:55 2006 From: fhkms at adelphia.net (fhkms at adelphia.net) Date: Wed, 11 Oct 2006 8:28:55 -0400 Subject: [K12OSN] off topic - firefox history files Message-ID: <21201619.1160569735040.JavaMail.root@web38> Hi all, In a routine audit of the students internet history (firefox on the latest k12ltsp), I found some questionable stuff.

While that doesn't solve the problem for "right now", it will solve the problem for "tomorrow". Infact, you're probably better off doing it this way, anyway, as you can start doing things like blacklisting certain sites and marking them with custom warning messages (such as "You got caught. Don't do it again!"). Also, with regular reviews of where people are visiting, you can either set up another proxy server to take the "recommended website traffic" such as Google, encarta, your local administration offices, etc. and a lower bandwidth link to take the non-approved sites (such as hotmail, myspace, etc.) meaning that your high bandwidth link is used for what your organisation is actually supposed to be providing, and then whatever's left can go to the other sites. Perhaps a regular review of what's going through the lower capacity proxy will turn up some useful sites that can then be moved onto the primary proxy? And before you ask... I wouldn't have the first clue about how to actually put that into practice!!

So its neat to see other tech leaders take notice. I will be bringing a small "server," a couple of old PC's and an old tray load iMac as a demonstration on how to use LTSP to "recycle" old workstations. In our school division there are hundreds of old iMacs that are now too slow, too old of an OS to be very useful anymore. But they continue to litter our computer labs. They make GREAT ltsp clients! So for about $110/workstation you can have a modern up2date, blazing fast computer lab again. You thought the $100 laptop was only for poor communities in India and Africa. We can accomplish the same value for your buck with LTSP. I have already done 3 computer labs in my area of the school division. I am working on joining 2 more schools with fibre and then they both get their old iMac labs upgraded to LTSP from a single server.

Remember the number one benefit is not cost savings on initial systems purchase but on ease/cost of maintenance. *************But be sure to explain FOSS carefully.************** *steps on soapbox* After listening to Steve Hargadon podcast interview of Maddog. k12opensource.com I remembered my conversation with our districts IT admin. I think the main issue holding back adoption is getting people to really understand and BELIEVE in FOSS. The response I got back was that the "Open Source development model was not something the district could rely upon". Have you ever tried explaining FOSS to someone who has never heard of it before? After about TEN minutes of explaining they may understand the constructs/rules by which it operates but I would be very surprised if they understood the implications and consequences. I think part of the reason Cath and Bazzar was so revolutionary was that it was the first explanation of this seemingly counter intuitive phenomenon. Problem is most people will not read it, I haven't even read every word of The C and B. Most people when they hear the word "Free" immediatley think "Nothing is free!" or as ESR puts it "It must be cheap/shoddy quality". The first question I usually get is "if it's free how do they make money?". Convincing people in positions of power (who are not FOSS savvy) that the development model is reliable and robust is difficult especially when they are not directly paying money for the software. I've heard comments like "what if the devs decide to stop work on the project? Then where are we left?" If you already have thought about this question (which I don't believe everyone in FOSS has) you can reply that the developers are usually the people who need the software the most so they have a vested interest in seeing continued development. Also since the devs are also (usually) users of the software there is good communication between users and devs. In the FOSS world this close relationship between users and devs produces great software as it's in a continual state of improvment directed by user requests/desires. So FOSS development DOES have direction: The best kind. In addition the potential to participate in FOSS should not be overlooked (as it usually is). Imagine if a school district says "we need this feature" so they hire a dev (or pay an existing dev in the project) to add it and in the process provide that feature to everyone else on the planet. Sometimes this opportunity gets a response of "Why should we pay for something others will benefit from?" But remind them it also means others improvments will become your benefits. In the regular business world this IDEA is not something which is not second nature as most businesses work on a "Dog eat dog, everyone for themselves attitude". This doesn't work in FOSS. Bottom line. It's not easy to truly understand and believe in FOSS. It's taken me years to discover it's full potential. THIS is, in my opinion, the biggest barrier of adoption. *steps off soapbox* Joe Guenther > LANtech - Didsbury Schools > Chinook's Edge School Div. #73 > > _______________________________________________ > 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/ -------------- next part -------------- An HTML attachment was scrubbed...

In-Reply-To: References: Message-ID: I'd like to add what Robert has said. I just came from ITEC (Iowa Technology and Education Connection). I looked and looked for open source seminars there, and really only heard 3 where open source software was mentioned, Moodle being the only FOSS project to have its own seminar. The rest only had open source mentioned in passing. Most vendors got a sour look on their face when I mentioned open source, with the exception of the people selling the web/mail/spam/virus filter appliances. Of course their stuff was built on open source, but they packaged it all together to work nicely. In one seminar, entitled "The Great OS War of 2007", the speaker mentioned Linux at the very tail end of his seminar, saying that it was "still in development" and "comparable to Mac OS8 or Windows 95 in its development stage". I really didn't agree with that last comment, but here's the "expert" (actually, this guy was a Mac fanatic) giving his opinion as fact to everyone that Linux "may be ready by 2009". It discouraged me so much that I intend to do 2 presentations, one on FOSS in general (with an emphasis on mostly cross-platform applications), and another on K12LTSP. [my turn on the soapbox] While I know shame isn't always the best motivator, I intend to share my opinion that any district that DOESN'T adopt open source software obviously has too much money to waste. Most of those here in Iowa are rather pragmatic, and if you can get something that does what you want for a good price, you get it. If it's free, even better. To me, its like a smoker who complains about not having enough money for rent/gas/food/children's school supplies. Perhaps if they were smarter about how they spend their money, re-consider what's really necessairy and what isn't, they would have the money to cover necessairy things. If we weren't addicted to commercial software, we can accomplish the job, and still have money for things that are needed like that new roof for the high school, an upgraded electrical system, new plumbing, that new addition to the grade school (all things our district currently needs to pay for). [/end soapbox] So consider any reply you make to this thread as one that I may potentially be discussing at ITEC 2007. I'm always up for more good ways to convince people FOSS is the way.

Ed_?= tech In-Reply-To: References: Message-ID: Maine has their annual big tech conference this Friday and there are several Open Source offerings for folks to attend....and guess what? This year I am not presenting! Why is this important? It shows how far we've come....the movement has spread beyond just a select few....and has now reached the others. The biggest thing I have learned over the past few years is "Just do it". Don't spend too much time making a big deal about it....or pontificating about the value of FOSS or projecting a "holier than thou" attitude about FOSS. Simply start using it as if it were any other piece of software. Conduct workshops on how to use it...just like anything else....and then when folks ask about how much it costs or how to get it....then explain briefly a little bit about FOSS and so forth, but not too much....as it's human nature to assume "Free" is substandard. WE as linux geeks...understand the concept, many do not. They can be won over, but it's a slow process. Once you understand that....then and only then can you begin "winning" them over. You'll eventually see things get to a point where there will be a paradigm shift in thinking and suddenly there will be more widespread adoption. Maine has a one-to-one laptop program that is now in it's second round (5th year). We have Apple iBooks for every 7th and 8th grader in the entire state. It's a program that has worked wonders for us here in Maine. Not every state or district has had the same success, but I attribute some of the success to the attitude behind technology in our state in the first place. The image that was created for the laptop project this time around (we are on our second full-scale deployment...as the laptops are part of a 4 year lease program...we are in our 5th year...so this year we have all new laptops) has a number of Open Source titles on it. NeoOffice, GIMP, Cyberduck, and a bunch more. Now think about this...the image was created by the project team (Apple folks and state DOE folks) based on input and lessons learned from the past. We have come a long way. Now every 7th and 8th grader in Maine is using FOSS on a daily basis....no one made a big deal out of it....it just happened. This is cool....now kids are downloading and installing OpenOffice on their home computers to be more compatible with NeoOffice (mac version of OO). When I present at conferences about LTSP....I tell folks...don't ask for permission and go before the school board etc.....just do it....roll out an LTSP lab....let it show everyone how it works and saves money and build on that success. If you make a big deal out of it...folks will become naturally defensive, but if you install it with little fanfare and simply show that it works without interfering with the general flow of things....you'll turn heads....slowly, but they'll start to see...."hey, this can work". As for the vendors and the sour looks....in Maine...more and more vendors are realizing that if they don't develop Linux versions....they're going to get left behind. It's amazing how many vendors each year show up at this conference with a new attitude and a new product line geared toward Linux. Just like in Field of Dreams....build it and they will come (or come around).

He provided a PowerPoint presentation to go along with the interview, which I have converted both to flash and Open Documents formats. Click on those links and you can follow along with him. Some other links from the interview are here. For me, one of the real high points of the discussion was his description of the two different ways in which FLOSS is used in schools: "FLOSS in Education," and "FLOSS as Education." "FLOSS in Education" is the use of FLOSS for regular computing tasks, whereas "FLOSS as Education" is the teaching of programming--and collaborative programming--by using FLOSS. Thank you, Ragavan, for giving me a better vocabulary for something I end up talking about a lot.. Another sigificant aspect of the interview was Ragavan's descriptions of where HP as a company has seen significant value in the use of FLOSS internally. HP and IBM are both visibly posturing to show the world their support for Linux and FLOSS, but to hear how HP is actually benefiting from FLOSS itself is pretty compelling evidence of the real-world impact of FLOSS. ----- http://educationbridges.net/k12opensource/wp-content/uploads/rms.mp3 http://educationbridges.net/k12opensource/wp-content/uploads/rms.ogg "Richard Stallman on Free Software in Education" Richard Stallman and I emailed back and forth several times before he agree to an interview with me on Free Software in Education. Not that Richard is not passionate about Free Software in Education, but he has some strict requirements about the presentation of his material. As the founder of the Free Software Movement, he is both passionate and principled, and doesn't want to dilute his message. When I called him last Saturday to start the interview (and yes, the date I give in the recording is wrong...), he asked if I remembered his two conditions for the interview. I said that I did, but he repeated them for me: to avoid common errors, I needed first to use the term "Free Software" only and not "Open Source," so as not to associate his work with that label; and second, to not confuse GNU and Linux. As you will hear in the interview, Richard cares very much about being exact with language. And, I think, for good reason. In the interview, Richard defines the use of the word "free" in the context of software. He also defines the four essential freedoms that are behind the Free Software Movement, and the four reasons that he believes that schools should use exclusively Free Software (see also his essay on this topic). And lots more--including the fact that he likes Wikipedia, which makes A TON OF SENSE since all text at Wikipedia is available under the terms of the GNU Free Documentation License--which Richard wrote! That might help to explain why Eric Raymond was so vocal about not liking it in his interview with me... I think you will find this interview interesting listening. -- 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 jguenther at chinooksedge.ab.ca Thu Oct 12 03:54:11 2006 From: jguenther at chinooksedge.ab.ca (Joe Guenther) Date: Wed, 11 Oct 2006 21:54:11 -0600 Subject: [K12OSN] Advocacy: barriers to adoption (was LTSP presentation to=?ISO-8859-1?Q?

However, when it's already implemented by someone like yourself the higher ups are happy and supportive. But when they are faced with the decision to implement it from the top down (not from the bottom up as it is most of the time) then they become much more interested in the license. It's been my experience that this is when they get cold feet because they don't completely understand (believe in) FOSS. However, I completely agree that the limited time you have to present should be spent on demonstrating the software not FOSS evengelism. But at some point in the future the concept of FOSS is going to come up if they want to offer it as an option to schools.

They' also offered significant discounts to schools on those policies. If you look at the wording of the policy, you'll find something quite insidious: The cost is calculated on the total number of PCs the licensee has, whether they are x86/Windows, or Macs, or Linux boxes, whether they use MS software or not. This is a brilliant move for MS that is bad for everyone else, because it removes any advantage a school might get by even _trying_ an alternative. You could propose, say, OOo, in just a lab to cut licensing costs by 30 machines. Except with SAP, you don't save any money because you're paying for MS Office whether you use it or not. THAT was one of MS's primary goals with SAP, to remove any motivation for even trying something else. People in my office say "We can use SQL server for a project and not have to pay for it because we have a site license." Fools. We pay for it, in the site license, which we settle up each year, in which they look at how many machines we have running MS stuff. It may not come out of that particular department's budget, but the company still pays for it. MS isn't a charity, and like any business, ultimately they're after your money. There's nothing wrong with that, as that's the way business works. But if you use their stuff, one way or another, you'll pay for it. Petre Joe Guenther wrote: > I really agree with David Trask...

It is not a very Linux-friendly province. The educational leadership does not listen to the grassroots much and the bosses are pro-Microsoft. AB Education gives stuff away to schools that only works with Windows/MacOS, for instance. The province is rolling in oil cash and they seem at one time say teachers cost too much and on the other hand they are generous to Microsoft. Schools are squeezed. Many have ancient computer systems (including XP) that crash frequently and they have little choice of software because they only know to buy shrink-wrapped. The tech guys mostly know Windows and are reluctant to learn something new. The teachers may be worse. They run away screaming in fear at the mention of an alternative universe. I will never forget the time a principal was giving me a tour of a school and I chatted with the computer teacher. He said he wanted to talk with me afterwards. In that private conference he intoned solemnly that his '2000 server had been running without a crash for six months and his 'XP machines only crashed daily so he was not about to make any changes... The server crashed pretty regularly when I worked there. The machines I set up in my classroom never crashed, but he still was not interested. Until a critical mass of knowledgeable folks discuss the issues no real choices can be made. Presentations may work on the right people at the right time and likely can do no wrong. I get mixed results. Some people who could make a difference do not even reply to my e-mail. I have met several "consultants" who have never used Linux proclaim it is not ready, never will be and is strictly for amateurs. I was showing Koha and Emilda to our librarian and a visiting consultant. The consultant made all kinds of untrue statements about Linux and FOSS after I left the room. The consultant wanted the school to spend thousands on a proprietary package that did the same stuff... It goes on. It has taken a decade or more for attitudes to form and it takes time to change them. I am in a school in Manitoba that ran out of options. They budgeted so little for IT that no Windows solution could fit. ;-) I gave them an LTSP system that gives them more than twice the capability they could have had with Windows and will be much easier to maintain. So I found a little chink in the walls of the monopoly and advanced. Now there are hundreds of people who have used Linux in place of hundreds who had never heard of it. I recommend decent server hardware when demonstrating LTSP. The server costs so little of the total cost that it does not pay to scrimp there. You want snap to your presentation. Give them lots of RAM with lots of cached files and RAID1. Max out your disc heads. Use gigabit/s to the switch for sure. Make sure any clunker clients have 100 megabits/s NICs. Include an LCD monitor, and laser mice too. A doorstop looks a lot better if the user interface is new. I really like the compact/fanless new thin clients. Some are less than $200.

You don't really authenticate _on_ the client which is what that would control. You authenticate against a gdm login on the server. On a normal Fedora/RH setup, you would use authconfig-gtk to set up the authentication methods, then the /etc/pam.d/system-auth file that it builds is included by most of the pam service entries. -- Les Mikesell les at futuresource.com From tom.hoffman at gmail.com Thu Oct 12 18:36:24 2006 From: tom.hoffman at gmail.com (Tom Hoffman) Date: Thu, 12 Oct 2006 14:36:24 -0400 Subject: [K12OSN] Advocacy: barriers to adoption (was LTSP presentation to Ed tech In-Reply-To: References: <452DBC63.80501@chinooksedge.ab.ca> Message-ID: <92de6c880610121136k7fc77ea9ve17e18db3a00b491@mail.gmail.com> On 10/12/06, Robert Arkiletian wrote: > > > On 10/11/06, Joe Guenther wrote: > > > > I really agree with David Trask...

To make it always network boot, boot the Mac OS and go into some system config tool which I forget to tell it to boot from the network rather than the hard drive.

Then set about to get the clients up. Ahhh ... which kernel is that? 2.6.17-1.2187? I've had lockups with that kernel on 5 out of the 6 Athlon64 systems I manage - typically about 30-60 seconds after a login screen appears. Booting to text screen and/or disabling APIC make no difference. Try booting to the older kernel to see if the problem persists. If you're worried about kernel exploits, you might try the latest kernel from the FC6 stuff.

We could keep the server up all day long with no problem. But as soon as a thin client tried to start X, BAM!, down it goes. I'm thinking it's an xorg issue but don't have the time to fully dig into it. We were supposed to be done with this school install two days ago and at this point we have barely begun. > > Calvin > > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -- James P.

It is not recommended that the passwd and group files are just replaced. In the one from the old server, cut out everything up to where the users actually start. Then on the new server, cut out everything from where the users begin. Then add the contents from the old passwd to the new one and same with group. This way, system ownerships will remain the same and user ownerships will as well. be sure to get /etc/samba/smbpasswd and secrets if you use samba for winders connectivity.

That's interesting - it means the problems with 2187 aren't limited to AMD CPUs. Here's hoping the 2.6.18 kernels in FC6 don't share this problem.

Too bad its not > opensource. Anyone know of an opensource alternative? I've never quite understood their approach, or why libraries are buying their hardware (Userful was originally targeting libraries...not sure now). Here in Brampton, ON, one of the libraries I visited has Userful boxes set up in a few locations. It's nice that one box can run 10 stations, but it's really short sighted: the library ends up having to run and maintain one box per "node" (I'm using the term node to refer to the group of 10 keyboards/mice/monitors), and in this library's case, is also exposing the one box to the public! It seems to me a much more flexible, secure, and reliable solution would be to deploy Linux thin clients running off one big X server. That would also give libraries the opportunity to place workstations ANYWHERE, and as many as the one server could support. As it is, the workstations are grouped around the Userful server, and it can only support 10 on one box (last I checked). It might be good in a small library, but I don't see the benefit in bigger libraries. Still, it was quite a treat using a Linux box at the library! Userful does have a decent solution. Very easy to duplicate though. BTW, if Userful has changed the code in anything that is licensed under the GPL or other f/oss licenses, they have to provide you with the sources when requested. I don't know enough about what they've done to say if their complying or not.

It is my humble opinion (based on personal experience, mind you) that getting Linux or other F/OSS into big school boards is essentially a lost cause. The IT departments have too much vested interested in keeping Microsoft, and higher ups are too scared to implement anything else. Oh sure, motions are made to investigate other options, but that's all they are. I haven't heard of a single big school board in Canada switching to a Linux environment (be it LTSP, K12LTSP, Thinstation, etc.). However, when one of them finally does, the rest will quickly follow, or as quickly as their budgets will allow. Until that time, it's the small boards that will continue to change over. Those boards and their students will be better off, of that I'm 100% sure.

I see in the archives that several of you have been here before, and that Chuck has a copy of his pam_mount.conf at http://wiki.ltsp.org/twiki/bin/view/Ltsp/WinIntegration I am hope that someone can point me to a good step by step for this. Specifically I would like to know which files in /etc/pam.d/ need to be edited. Here's what I think needs to be done: 1. install libpam_mount. On Ubuntu 6.06 LTS I did: sudo apt-get install libpam_mount 2. edit /etc/pam.d/common-pammount, commented out: #auth optional pam_mount.so use_first_pass and added the following bottom of the file: auth required pam_mount.so use_first_pass session optional pam_mount.so use_first_pass 2. Then I edited /etc/pam.d/gdm to reflect my interpertation of the directions in /etc/security/pam_mount.conf #%PAM-1.0 auth requisite pam_nologin.so auth sufficient pam_winbind.so auth sufficient pam_unix.so nullok_secure use_first_pass auth required pam_env.so #added the following line to allow automounting win shares via pam_mount auth required pam_mount.so use_first_pass @include common-auth @include common-account session required pam_limits.so session optional pam_console.so #added the following line to allow automounting win shares via pam_mount session optional pam_mount.so @include common-session @include common-pammount 3.

My school just spent well over $10,000 on a district mandated M$ 2003 server (I don't even want to know how much of that is for licensing). It provides ADS/PDC(LDAP/Samba), IIS(Apache), DHCP(dhcpd) and a M$ nameserver(BIND) . However, the district has decided to use Mambo as the CMS for the school. Mambo is a Free Open Source CMS which uses PHP/MYSQL. But on a Windows box!? I find this oddly humorous. Linux dominates the web with LAMP (Linux Apache Mysql Php) boxes.

In-Reply-To: References: Message-ID: <45338490.9040604@maltzen.net> I don't have any experience with those particular apps, but it sounds like you may be having network bandwidth/contention issues. I'm guessing that you don't have as many of the computers at home as you have in the club. Are you using a gigabit network connection between the server and the clients? That is, a 100Mb card in the server and in each of the clients, all connected via a 100Mb switch, is adequate for up to six clients when graphically intensive apps (such as you are using) are involved; and depending on exactly what you're doing, perhaps fewer than that. Above that, put a gigabit card in the server, and get a switch with a bunch of 100Mb ports and one or two gigabit ports. For each client, 100Mb is sufficient, but the server needs to be gigabit. You could also be cheap and buy a 5-port Gbit switch, plug the server into it, and then daisy chain some 100Mb switches into it, and plug the clients into those 100Mb switches; it's a bit clumsy, but may be a cheap way to test to see if it solves the problem.

The cable is used for communications with a program on the computer, and that program (or clients) is responsible for shutting down the system. If you have a choice, I'd suggest getting one with a USB cable. If you're using an APC (IMHO the best of the consumer-quality UPSes), install apcupsd. If you're using FC5 it's available from the "extras" repository. I know "nut" and "nut-cgi" are available in the "core" repository, but I've found apcupsd to be easier to setup (probably due to its product-specificity).

Well, the UPS doesn't really send a shutdown. There's an apc daemon that monitors the status of the UPS. It detects when it's on battery, or when it has a power source. You can set the daemon to trigger a shutdown when it senses the battery has a certain charge remaining. The daemon will also cancel shutdown if power comes back on before the shutdown actually occurs. I prefer a warning, so if I'm at work when power goes out, I can save stuff before the shutdown occurs. They will use either the USB or serial connection for monitoring the status.

Message-ID: <4533D230.9050605@maltzen.net> We haven't had any discussion for a while now as to how well SATA drives scale up in a K12LTSP server. It used to be, back in the PATA days, that an ATA (also known as IDE) drive would handle up to 10 clients, but going any higher than that resulted in poor performance that could be addressed only by going to SCSI with its ability to re-order queues and so forth. But SATA has been out for a while, it now has many of the features of SCSI, and I see that 10K RPM versions are available, and so I'm wondering if the consensus now is that SATA is good enough for small and even mid-size servers, where by 'midsize' I mean roughly 25 clients hanging off of it.

What about 7200RPM SATA drives? With 25 users it would be worth trying. FWIW, a local Linux-based hosting facility (tummy.com) swears by Hitachi drives, and the newer Hitachis feature "Native Command Queueing", which I believe is equivalent to the queue reordering you mentioned. If I was putting together a new server, I'd probably try one of those Hitachis. They're cheap enough that you could try, say, a 250 gig model, then relegate it to some other task (like backup storage) if you found you had to replace it with a SCSI drive. Yes, you could get a 10K RPM Maxtor drive, but they're much more expensive, and currently Maxtor reliability is suspect (http://www.hardwareguys.com/picks/harddisk.html).

The cheaper APCs don't do true serial communication (i.e., sending data to the computer). Instead, they set certain signals (like CTS, IIRC) to indicate their condition. USB allows for real communication with the host computer, and I _believe_ that means real data gets sent to that host. For example, here's the output of "apcaccess" on my workstation: APC : 001,034,0890 DATE : Mon Oct 16 12:59:50 MDT 2006 HOSTNAME : source-server.prosocial.local RELEASE : 3.12.4 VERSION : 3.12.4 (19 August 2006) redhat UPSNAME : source-server.prosocial.local CABLE : USB Cable MODEL : Back-UPS NS 600 UPSMODE : Stand Alone STARTTIME: Fri Oct 13 13:05:46 MDT 2006 STATUS : ONLINE LINEV : 118.0 Volts LOADPCT : 0.0 Percent Load Capacity BCHARGE : 100.0 Percent TIMELEFT : 42.8 Minutes MBATTCHG : 5 Percent MINTIMEL : 3 Minutes MAXTIME : 0 Seconds LOTRANS : 088.0 Volts HITRANS : 139.0 Volts ALARMDEL : Always BATTV : 13.5 Volts LASTXFER : Low line voltage NUMXFERS : 0 TONBATT : 0 seconds CUMONBATT: 0 seconds XOFFBATT : N/A STATFLAG : 0x07000008 Status Flag MANDATE : 2005-12-26 SERIALNO : 3B0601X00177 BATTDATE : 2000-00-00 NOMBATTV : 12.0 FIRMWARE : 18.w1 .D USB FW:w1 APCMODEL : Back-UPS NS 600 END APC : Mon Oct 16 12:59:51 MDT 2006 I'm reasonably certain a serial signal-only connection can't convey that much information to the host (I've no great emotional stake in this, and won't complain if somebody can post similar output from a signal-only UPS). > > I am using the CentOS 4 based k12ltsp. RPMs are available for RHEL3 at the apcupsd site (http://sourceforge.net/project/showfiles.php?group_id=54413&package_id=73150). I think that's the closest match to CentOS 4 (being directly descended from RHEL4).

This is the first PC I've ever built from scratch. MSI Mobo, Dual Core 805 Proc, Gig of Ram, 120Gig ATA drive. I mention this because my problem might be in the BIOS which I've never had to set up from scratch before. The server is really working great. I can't quite pin it down, but the combo of this faster server and 5.0 is really great (thanks Eric). The first client I tried (an old GX110) booted up beautifully with no tweaks to lts.conf!!! Anyway, one of the few problems I'm having is that when I'm logged into the server console as root, the server eventually goes to sleep. Actually it's just the console, the monitor light actually stays green (and the monitor is hot) but all the button clicking and keyboard tapping and mouse moving in the world won't "wake it up." I have to go in via ssh from another box and do a "shutdown -r now" to regain console access. I've tried disabling (and other settings) of power management in the BIOS. I've tried turning "go to sleep" to "never" in the Gnome power management control panel. I don't really know whether this is a BIOS thing or Linux thing or both. Does anyone have any suggestions for how to fix this? I guess it won't be much of an issue once the server is up and running (it runs the clients great in this mode and I won't stay logged in as root for very long) but while I'm still setting up the server it's a drag, and I don't want to have to reboot every time I need console access in the future.

I have had up to 37 clients on at one time. Usually there are a lab of 25 clients plus 6 stations in the library running all day. Home folder storage is done on a Novell server though. But the LTSP system runs on this box with dual Xeon 2.4GHz and 4 Gb RAM with these 2 - 120Gb 7200rpm SATA in RAID 0 on Adaptec 1210s RAID (a real cheapo). The ONLY time there is a noticable slowness is when all 25 boot simultaneously and then when they all start OpenOffice simultaneously. Once they are all up nobody notices any slowness. I think the SATA RAID make great little budget servers personally.

Although I use scsi in my server my advice would be to make a software raid 1 for / , /var, /tmp on 2 fast 10k rpm drives and /home and swap on another 2 (bigger) 7200rpm drives. Intel 945P chipsets usually come with ICHR southbridges (which have AHCI needed for NCQ) that have 4 SATA ports. Or if you want lots of space for /home then buy another cheap Sil3132 based PCI-E SATA controller (I think SYBA makes them) for another 2 SATA ports and make a RAID 5 for /home with upto 4 drives.

Whether the data port is serial or usb makes no difference. The Back-UPS vs the Smart-UPS have a large amount of functionality difference. The Backups is simpler and has only a timer function. Once it goes on battery, the timer starts. At the end of the timer, it send the shutdown command to the host. The smartups has much more of a command set. It supports battery condition testing and and can signal a power down when the battery falls below a certain level. More importantly, it can hold of on powering back up until the battery has reached a certain minimum runtime level. On my current install, we have Smart-UPS XL 3000VA RM 3U models that have both serial and USB connectors. The same data is on both ports. One nice thing about these (and all Linux systems can be setup to do this) is when the shutdown command is issued, the apcupsd can be told to also send it to a group of other machines. In my current case, there are several servers that run off the UPS in the rack. If the UPS is going down that powers the main login/NFS-/home machine, every other server will need to also shut down as they will have nothing they can do. If a UPS signals to a boot/app server the remaining app servers can stay up. So the UPS is told power back up when the AC as back and the batteries are back up to enough time to allow a partially booted system to shut down gracefully. The first box up is the NFS server. It will then tickle the other machines with Wake-on LAN calls (as soon as I can finish that process). > > USB allows for real communication with the host computer, and I > _believe_ that means real data gets sent to that host.

The Battlefords went with Sun Xserver/thin clients. My little independent school started with Ubuntu+LTSP from the first day so we did not have to displace that other OS which had been on 50 old machines in the previous building. We have 96 thin clients deployed now and I am trying to get the multi-seat X to work on 13 custom built machines. It's a start. I can tell you, I meet people who run Linux at home in my classes when only a few years ago I would find in the whole school no one who had heard of Linux. It is happening.

It has excellent speed on reads as it can send the heads in different directions and part of the file from drive A and another part from drive B. NFS can't handle a drive hiccup error during a read from a mirror drive that is failing. It will cause a hard lock of the clients. I'm not done on the diagnostics yet to determine if the kernel passed a drive read error through the RAID process and into the NFS delivery process but it was a disaster no matter how it happened. I'm still considering it as a kernel fault (software RAID) as it should have trapped the error, failed the drive and then reverted to the other drive. > > Petre > > _______________________________________________ > 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/ > _______________________________________________ > K12OSN mailing list > K12OSN at redhat.com > https://www.redhat.com/mailman/listinfo/k12osn > For more info see -- James P.

This is very interesting. I would have thought the failed read would have caused the drive to be kicked out of the array and the other working drive to complete the read and THEN nfs send the completed successful read. -- 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/ -------------- next part -------------- An HTML attachment was scrubbed...

I'm trying to get SimCity 3000 Unlimited running on my new k12ltsp server. I had it running fine on my old server using "LD_ASSUME_KERNEL=2.2.5 /usr/local/games/sc3u" and a patch for sc3u from lokigames.com. Anyway, much googling led me to a workaround to get it to work under FC 5. I needed to download some old FC3 libraries and put them in a folder, then invoke the new libraries by invoking SimCity (sc3u) using a script file. Here's the script: ~~~~~~~~~~~~~~~~~~~~~~~ COMPAT=/usr/local/games/SC3U/loki_compat/ export LD_LIBRARY_PATH=$COMPAT LD_ASSUME_KERNEL=2.2.5 $COMPAT/ld-linux.so.2 /usr/local/games/SC3U/sc3u ~~~~~~~~~~~~~~~~~~~~~~~ I'm calling the script from a launcher (or command line) via "sh /usr/local/games/SC3U/sc3u-compat.sh". So, anyway it was working perfectly on the server console. Looked better than ever. But I go to try it on the client and *nothing* happens. I tried invoking the script from the command line (which worked on the server) and I get the following error. ~~~~~~~~~~~~~~~~~~~~~~~~ _X11TransSocketINETConnect: Can't get address for ws253.ltsp Graphic System: Could not init SDL: No available video device Check your DISPLAY environment variable ~~~~~~~~~~~~~~~~~~~~~~~~ This looks like a DNS issue, (or maybe an lts.conf) but I don't know what to tweak in the DNS to provide display info to the game. I'm dead in the water. Google didn't have anything for me. Any ideas how to get around this? I'm so close. I probably put in 3 hours getting SimCity working on the server. Oh, by the way GCompris, Wesnoth, tuxpaint, all work on all clients some fullscreen, some windowed. (Thanks Eric!)

Possibly a problem with the $DISPLAY variable. So, lets see what your $DISPLAY is set to. Near the top of your script, add this: echo "DISPLAY=$DISPLAY" >/tmp/display.out Then, try running the script After it fails, take a look in /tmp/display.out, see what DISPLAY was set to. That might provide a clue on how to proceed. It could also be that none of the X11 libraries are available. I don't think you can use the standard system X11 libraries, because your program is linked against a much older version of glibc. You may need to copy the X11 libs into your /usr/local/games/SC3U/loki_compat directory. But, i've never actually tried doing what you are doing, so I could be wrong.

I would classify all those boards as small. When I say big boards, I'm talking about boards like the TDSB (Toronto), PDSB (Peel), HDSB (Halton). That's were change is either not happening, will never happen, or is proceeding at a glacially slow pace. Interesting note: My company was the one that helped roll out a 122 seat LTSP pilot at the NWCSD #16 in North Battleford. The cost difference between the LTSP setup and the Windows projections they were doing was huge. I believe they switched entirely over to a Linux thin client setup based on that initial trial. > I > can tell you, I meet people who run Linux at home in my classes when > only a few years ago I would find in the whole school no one who had > heard of Linux. It is happening. Yes, it definitely is. Smaller school boards realizing the benefits.

We used RAID 1 because of the redundancy and since most critical disk activity is actually reads not writes (ie opening programs), the performance difference is either negligible or favors having the data on 2 disks. The large caches of the new drives (16mb are supposed to be killer) also help. regards, William On Mon, 2006-10-16 at 23:18 -0400, k12osn-request at redhat.com wrote: > Message: 20 > Date: Mon, 16 Oct 2006 19:02:52 -0600 > From: Joe Guenther > Subject: Re: [K12OSN] SATA drive for server with 25 users? > To: "Support list for open source software in schools." > > Message-ID: <45342BBC.6050404 at chinooksedge.ab.ca> > Content-Type: text/plain; charset=ISO-8859-1; format=flowed > > I run a LTSP server with 2 SATA drives on RAID 0 - striping and it > seems > to run just fine.

A few points: 1. The gnome and gconf directories in ~/ don't get created until the first time you log into a gnome session. They don't come from /etc/skel 2. When recreating users, be sure you recreate usernames with the *same* uid as they had before. Linux really only cares about uids and gids (ie, numbers like 1000 or 1001) and then maps usernames (bob, frank) to those numbers. "bob" with uid 1000 is not the same user as bob with uid 1001. 3. If you recreate usernames with different uids, be sure to: chown -R . /home/ Also, be sure to delete the directories and files in the /tmp directory, as many are created with names like "virtual-", and your new username with the different uid will get confused. 4. Many times I have seen "stuck" sessions in Gnome because of hung gconfd-2 processes that never died from previous sessions. Killing that process usually "unsticks" things.

Everything works fine for a user but when you logout, it cleans up the screen but leaves just the wallpaper and then locks up X. It doesn't matter if you login on the graphic console, a VNC session or a thin client. It does the same thing no matter what. Takes a reboot to clean out all the processes unless you kill each one owned by the user who logged in individually. Second, I have some newer Intel motherboards that the boot won't find. It says it can't find a NIC but that PCI NICs shoud be autodetected (they aren't) and ISA NICs require manual setting. They should be PCI if they are integrated, shouldn't they?

In our district, very few if any existing machines can run the full blown version (Aero?) of Vista. We haven't even completely migrated off Win 98! They may be getting free copies of Vista but they aren't getting free PCI-E slots or 1 gb ram sticks. (OTOH, viruses and spyware are still free.) 2) At some point, the success stories from the smaller installations will add up and uncomfortable questions and comparisons will be made: "Why does xyz district have twice as many PCs per student than we do?" 3) What must be done - change has to come from outside the "establishment". Very often, it's higher government and private officials who understand that your students need to be prepared to compete with their peers from all over the world and 45 minutes a week in computer lab isn't going to cut it. Spend time lobbying them and convincing them of the approach. Go to the boss and if that doesn't work, go to their boss. 4) Take doubters to a school where OSS is installed. Simply, people won't believe it till they see it. We've seen time after time people come to our school not quite grasping the concept until they see classrooms full of computers. Quite frankly, the servers could be running off hamster wheels instead of Pentiums and they wouldn't care. What they see are students in front of working computers. 5) Don't make it about the technology or the cost savings. Make it about getting as many computers and software in front of the kids as possible. Eyes glaze when we start talking about clients and kernels. Student results, test scores, teacher satisfaction are what matter. Find out how the smaller districts that do have OSS are doing in testing and compare it to the districts with proprietary software. That's the comparison that they can't fight. There will be a tipping point, no doubt. OSS is fundamentally, like education, a collaborative process. best regards.

But it might help to know what it is you are trying to accomplish and why; there may be a different way to accomplish what you really need to do. My guess about what you are trying to do is simulate the MS Windows local/domain logins. The fact of the matter is that Unix (and Linux) have a different design and it doesn't work that way. Changing your authentication realm, at login, on the fly is the biggest obstacle. However, there are other possibilities if you don't have to masquerade as Micosoft to do it: local logins and nfs automount under each users home directory (~/user/MyHome.net maybe), or perhaps something more exotic, like distributed filesystems (i.e. Coda). We don't know if you are talking about access over a WAN/Internet or only over a private LAN. We don't know if the laptop is used by one, a small number, or many users. A more precise description of the goal of the project would narrow the problem space, and maybe someone has already worked out something similar. Just because they may not have solved it in the way you imagine doesn't mean it might not still be solved.

There is a near zero chance that it work right for you, if you do manage to get it working, you have an exactly ZERO chance of it being supported. But, if you want try out something fun... Notes: * This is built on today's Fedora Development tree, which is pretty close to what the final FC6 should look like. Since the development tree changes every day, you'll need to pull all of the software from my server. I'll set it up to work with stock FC6 discs once FC6 is released * Only network installs are supported, ISOs do not work right now (the download will be several Gigs, you'll need a lot of bandwidth and a couple of hours) * Only the default "ltsp" configuration will work, you need two NICs and the first one needs the address of 192.168.0.254/24. * Only the default configuration will work out of the box * Only i386 clients work, no Apple support at the moment * Only PXE booting is supported, etherboot is not supported yet * A couple of the i386/PXE test terminals I have laying around crash-and-burn, don't expect your terminals to actually boot even if they are i386 with PXE. * You'll probably need 128M of ram or more in your terminals * None of the cool LTSP features, such as removable devices work yet * No "Education" apps are installed, just the LTSP-specific bits * A vast assortment of other show-stopping bugs, ugly hacks, and missing features * Don't worry, all of these caveats will be fairly easy to fix ;-) If you read this far, here are the install instructions: 1) get the boot image and burn it to a CDR: http://k12linux.mesd.k12.or.us/K12LTSP/testing/fedora-devel/images/boot.iso 2) boot your victim server off of this CDR. At the "boot:" prompt, type: linux ks=http://k12linux.mesd.k12.or.us/K12LTSP/testing/devel/ks.cfg 3) Take all of the defaults 4) After the install is completed, reboot and log in as root (Note: my last test install did not automatically switch to the GDM login, it booted to a text console and I had to hit "Alt-F7" to get the GDM login) 5) Open a terminal shell (Applications -> Accessories -> Terminal) 6) Run these two commands: build_ltsp_root /opt/ltsp/i386 install-ltsp-kernel 7) plug in a terminal, turn it on, and cross your fingers -Eric From ericbrow at gmail.com Wed Oct 18 20:44:31 2006 From: ericbrow at gmail.com (Eric Brown) Date: Wed, 18 Oct 2006 15:44:31 -0500 Subject: [K12OSN] JAVA?

However, calling it from a shell/xterm session does work. /usr/bin/childsplay is just a symlink to /usr/share/childsplay/childsplay.py. Running either file via Nautilus produces the same no-sound result. There was discussion of this problem about a year ago, with no resolution aside from my suggestion to check the .bashrc file for any clues. I removed the symlink and replaced with a two-line shell script that seems to work although I don't know why: . /etc/bashrc /usr/share/childsplay/childsplay.py Now running the program via Nautilus or from the menu works.

This is usually because I'm pretty humiliated by my own stupidity when I discover the solution. As in this case. This is indeed resolved now. I actually cracked the mobo manual and figured out what "s1 & s3", "any key wakeup", and etc. meant. And I think I finally got my BIOS set right. I also changed the settings in the GUI power management panels and I added: X_DPMS = Y X_DPMS_STANDBYTIME = 10 X_DPMS_SUSPENDTIME = 20 X_DPMS_OFFTIME = 30 to lts.conf for good measure.

A little hunting at Wikipedia reveals http://en.wikipedia.org/wiki/Advanced_Configuration_and_Power_Interface (look for "Global States"). S1 and S3 are power-saving modes. Since S3 ("suspend to RAM") turns off power to all devices except RAM, it saves the most power of any state which leaves the computer on. YMMV when starting back up - my 3.5 year old Toshiba laptop (running Core 6 test) doesn't reset video properly (I get a blank screen) after starting back up from S3. There are also S2 (rarely used) and S4 (suspend to disk, which shuts down computer after suspending (no power usage) AND works fine on my laptop). I guess I'll stop now, before dumping more possibly-irrelevant data into the mailing list. See the Wikipedia entry for lots more info.

Is this a generic netboot parameter? 2) If windows pads the root path with 000 do I need a symlink on my linux server from a directory called /opt/ltsp/i386000 > /opt/ltsp/i386 3) is the string for option 211 always tftp? 4) I glibly said I had the other boot parameters (ip, subnet mask, gateway) correctly set, because those parameters are the defaults handed over by the dhcp server on that scope. As I think about it I think I should be using an ip, subnet mask, and gateway consistent with that of the ltsp server (which sits on a different subnet than my test client. So if my LTSP server is 10.114.0.105/16 my clients should be 10.114.0.x/16 and use 10.114.0.105 as the gateway. Err, but perhaps I am getting myself in a muddle here. Thanks again.

On the first server, the K12 and Firefox installs went without a hitch; this included installing the Adobe Acrobat Reader v7.0.8 plugin for Firefox. The current installation, however, is not going so well. I've installed the K12 software and Firefox without issues, but Firefox doesn't seem to want to recognize the Adobe Reader plugin. Adobe Reader's plugin file, nppdf.so, is in the Firefox plugins folder, but Adobe Reader is not listed when I do an about:plugins command from within the browser. Additionally, when I browse to a site to test Adobe Reader, Firefox wants to use evince to open the .pdf (no surprise there). I've tried installing Adobe Reader v7.0.1 instead of v7.0.8, but the problem persists. Has anyone come across this mysterious activity, and if so, did you find a fix?

(Or am I way off base) Regardless, it's an amazing resource to have you on this list. With this simple statement: "I'm guessing you have a library mis-match problem." You led me to the solution. (The original posting I found through google helped too. He said he developed his idea by bringing over libraries from a FC2 computer that had SimCity working. I had tried to use his set of libraries that he had thoughtfully bundled up for people following in his footsteps.) Anyway, I tried a brute force attack on the problem. I simply rsnyc'd over directories of libraries from my K12ltsp 4.2.2 server (where SimCity worked before) into that "loki_comat" directory on my new server. I had to try 4 different directories of the same libraries until I found ones that worked. But it was indeed, obviously [to you], a library "mis-match problem". Thank you so much for helping me with my trivialities. If it means anything to you, you've helped make an 11 year old SimCity addict very happy. ck From petre at maltzen.net Thu Oct 19 20:57:31 2006 From: petre at maltzen.net (Petre Scheie) Date: Thu, 19 Oct 2006 15:57:31 -0500 Subject: [K12OSN] Playing CD's and DVD's on Clients In-Reply-To: <4537E1A9.2040508@snarlnet.com> References: <4537E1A9.2040508@snarlnet.com> Message-ID: <4537E6BB.7070402@maltzen.net> I put the same question to Jim McQuillan and Scott Balneaves a while back, and the short answer is no, music CDs just don't work that way, at least as far as LDA is concerned. My recollection was that it is a problem that ultimately can be solved, but the feeling was that it was a lesser priority than other things like getting sound working consistently and reliably (it mostly works now, but the architecture is not unified and applications are notoriously unpredictable as to whether they will work or not; the good news is the major desktops are saying they want to do whatever it takes to fix sound so it works flawlessly with LTSP.)

The best approach to doing this might be to run the player as a local app on the client. I thought the new muekow approach would make this easier but haven't had a chance to look at how it works yet.

I sorta thought I was asking a rhetorical question. Local apps always sounded tricky to me, but maybe I'll try it. Has it gotten any more turnkey in 5.0? Thanks for all the info and suggestions.

It's a quad P3 550 MHz, with 3gb ram purchased off ebay 2 years ago. When 20 kids open firefox and OO, things slow down quite a bit, and firefox may hang on several kids. I started searching for a new server on E-Bay, where I found a quad 2ghz machine with 8gb ram for $5k. My principal was reluctant to spend that much money on something used with no warranty. He said he'd prefer to have me purchase parts and use the assembly of the server as a teaching opportunity (something I've done with workstations in the past). My question for the group is, has anyone done this and encountered problems with some aspect of the machine in an LTSP environment? I'm looking at a Tyan board that will take 4 Opteron dual-core processors, probably 8 gb RAM, 2 gb nics onboard. I'm not too worried about disk space. I've only got 4 9gb drives in a raid5 right now, and only 44% is in use for about 60 students. I'm planning on something like 4 74gb 10,000 rpm drives with 8mb cache. Since the board is an extended atx, nearly any case that will take it is usually a server case with room for all the drives. Preliminary costs look to be $5k-$6k, which is the ball park I've been given. Anything I'm missing? Is this a bad thing to do? Shouldn't this run 20-25 clients very well for some time? Is it too much (I'm often accused of over-engineering anything I build)? Any comments welcome.

It's a catch-22 stemming from the PC architecture. -Desktop wireless can sort of be done, by using regular ethernet cards in the client wired to a WAP that connects to another WAP and then to the server. But you still have the bandwidth problems mentioned above, so this doesn't scale up very well. Search the archives of this mailing list and the LTSP list. A kernel was made to work a few years ago that could be booted from a floppy for one or two cards, but it hasn't been maintained because of the problems booting over wireless, so you don't get any of the modern features like Local Device Access.

I think for 25 clients one dual-core processor with 4GB, one gigabit NIC, and a RAID of 10K RPM SCSI disks would be plenty. Such a configuration could probably support 30-40 clients, depending on the apps being used. I just went out to Dell and configured a dual-core 2.8ghz Pentium, 4GB RAM, two 15KRPM 73GB disks in RAID1, and two gigabit NICs for less than $2000. And that includes a three year warranty. If you've got a $5000 budget, you could put the remaining funds toward servers & clients for other classrooms.

It comes with 2 ethernet ports and wireless connectivity. You can connect a terminal to ethernet port and the router transfers data over wireless. Bandwidth is an issue, since G is not all that fast, but it is perfectly acceptable for a few terminals. julius From henryhartley at westat.com Fri Oct 20 15:54:20 2006 From: henryhartley at westat.com (Henry Hartley) Date: Fri, 20 Oct 2006 11:54:20 -0400 Subject: [K12OSN] Flash 9 for Linux beta Message-ID: <403593359CA56C4CAE1F8F4F00DCFE7D0320DD1A@MAILBE2.westat.com> In case anyone cares (personally, I'm not a big fan of Flash but my daughter is - parts of disney.com require Flash > 7), Adobe Labs has released a beta of the Flash 9 Player for Linux.

Not all EATX cases will fit all EATX MB because of where the CPU's are located. I built my own but if I did it again I'd go pre-built from one of the mentioned vendors. Less headache better warranty/support. They also burn them in to make sure everything is fine.

Thank God; it's about time Flash stopped using OSS. Now that flash is finally using ALSA it should be significantly *less* difficult to get sound on the clients. There may be some initial but it paves the way for killing ESD for good and moving to PulseAudio. Of course, the first step is getting the PA server running on the clients to that PA clients on the server can connect. However, once that's done both the existing ESD apps as well as all ALSA apps should be able to use sound as PA provides an ALSA plugin and an ESD server plugin. It does mean Eric and Jim have some work to do, but I'm sure they're up to it ;-) --Shahms From hick518 at yahoo.com Fri Oct 20 19:16:09 2006 From: hick518 at yahoo.com (Rob Owens) Date: Fri, 20 Oct 2006 12:16:09 -0700 (PDT) Subject: [K12OSN] Use Linux DHCP instead of Active Directory DHCP?

The reason I'm asking first is that none of my TC's have a DVD drive. I'd have to install it first and I'd rather not go through the hassle if this is purposely disabled or otherwise known to not work. I've been told (here, yesterday) that audio CD's don't work, but still interested in video DVD's.

The recommended fix is to boot with this parameter: selinux_compat_net=1 (at the Grub boot screen, select the "2.6.18-1.2200.fc5" kernel, hit the "e" key, select the "append...." line, hit the "e" key again, append the "selinux_compat_net=1", hit the return key, then hit the "b" key ) -Or- you can boot back up with the earlier kernel that was working for you and wait for the next update (which sounds like it will happen soon) -Eric > ------------------------------------------------------------------------ > From: /Eric Harrison / > Reply-To: /"Support list for open source software in schools." > / > To: /"Support list for open source software in schools." > / > Subject: /Re: [K12OSN] New Kernel Issues!/ > Date: /Fri, 20 Oct 2006 08:23:35 -0700/ > >Casey Mynott wrote: > > > Hey all, > > > > > > I updated my server to the newest kernel for K12LTSP and after the > > > intital boot I just hang at a big X and everything stops.

The worst problem is (also as mentioned) you have to have a kernel of sorts working first before you can get wifi working. There's not enough room on a floppy for all this plus the basic etherboot info. There was a boot floppy image for wifi, but it was only for Hermes I/Lucent/Orinoco chipsets, and will not work with Realtek. I have one of those cards, and experimented with it. For one client, it would work fairly well. The easiest way to try this, is boot the machine to a Knoppix disc FIRST. Once you get wifi/networking set up, you can then at a shell prompt issue: X -query server This will give you a regular K12LTSP client login over wifi. If your client is minimal, you may not want the full Knoppix using your RAM additionally in the background. In that case, press F2 while the Knoppix disc is booting, and enter knoppix 2 That will start you in single-user mode only. Enter netcardconfig and you can get your wireless working like that, then start the connection to the K12LTSP server. For minimal machines, Damn Small Linux can work well for that.

Whenever I have to explain it to somebody for the first time, and they give me the "if it's free, it can't be any good" look, I remind them that people volunteer all the time. For instance, in the United States, soccer (the rest of the world calls it football) is very popular with young kids, and many towns have soccer leagues w/ many teams and many *volunteer* coaches. Same thing goes for Boy Scouts, church groups, alumni associations, etc. After they agree that what I'm saying is indeed true, then I say "What if you could electronically copy your kid's soccer coach and share him with the rest of the world? And what if you could get a copy of the coach out in California who's really good at teaching defense, and also get a copy of the coach in Texas who really knows how to get the kids to act as a team, etc. You guys would have the best soccer team on earth." I also remind them that just because writing programs seems a lot harder than coaching soccer (from their point of view), not everybody sees it that way. Some people love to program, and some of those people are nice enough to share all their hard work with the rest of the world. -Rob __________________________________________________ Do You Yahoo!?

Martin Dougiamas, the creator of Moodle, spent an hour with me talking about Moodle, what is is, where it is being used, and how a large Open Source program like Moodle is sustained. Martin is thoroughly engaging, and the interview goes by much too fast. Some notes: * Martin grew up in the desert of Australia, and his own schooling as a youth was from "The School of the Air." Through CB (Ham?) Radio, he and four or five other youth talked with a teacher who was 600 miles away, and every other week an airplane would stop by with school materials. Seems quite appropriate that someone with that background would 1) of necessity become a self-learner (again, reference the Doc Searl's interview and the "self-learner" aspect of the Open Source world), 2) understand the value of e-learning, 2) understand the nature of distance learning, and 3) see the value in learner-participation that lies at the philosophical heart of Moodle. * It was a test of Martin's patience for me to ask him to explain Moodle as though he were talking to a teacher who knew nothing about it, but he did a very good job, and I hope it makes the interview a better resource to the teacher community. There is a skill involved in not only managing a project as complex as Moodle, but also being willing and able to communicate its value in basic terms to new users. This impresses me about Martin. * Moodle isn't just for distance-learning situations. It is also built for and used in "face-to-face" learning or "blended" learning environments, and he mentioned its value in homeschooling. * The Moodle community that works on the actual software project is a model of the "community of practice" or "collaboration" that Moodle strives to help create for learning environments. They are their own best "customers" of the project, as they work to extend this core value of participation. For several months I have been wrestling with the two values of Free and Open Source Software (FOSS) to schools. The first is "FOSS in Education," which is essentially the use of FOSS programs that, for the most part, are just replacing proprietary programs which were already in use or which weren't in use because of their financial cost. The second is "FOSS as Education," where the use of FOSS programs introduces the student to the Free and Open Source world, and allows them to participate in collaborative programming. Jeff Elkner's work teaching FOSS programs like Python to students at Yorktown High School in Arlington, Virginia, is an example of this. What makes FOSS more than just a "cheaper" replacement of proprietary programs is this second opportunity--to engage students in very real-life aspects of a world that is becoming more and more based on collaborative work. The fascinating value that Moodle seems to bring to this picture is the ability that Moodle has to bring these collaborative opportunities into the regular classroom, bridging the gap between the worlds of regular computer use and Jeff Elkner's computer lab--because if "FOSS as Education" were only to take place in the computer lab classes, it's impact would be limited only to those technically-minded students. (Coming up for air now...) * Moodle is most definitely having a unique impact on the awareness and understanding of Open Sources software in schools. This is largely, I think, because it is viewed as "free" (as in cost) competitor to very expensive proprietary programs. Our Moodle demonstrations at the NECC and CUE shows have literally been standing-room only. But Martin is quick to point out (as was also clear about OpenOffice in my recent interview) that it is the combination of features and the benefits of the Open Source community that are driving the adoption of Moodle, and not the low cost. * The Moodle.org project is financially self-sustaining because of the commercial partnerships that Moodle has under the Moodle.com website. There are 40 Moodle partners who provide hosting, support, consulting, training, and certification (and some 200 additional applicants) who pay royalties into a Moodle trust. Funds from that trust go to pay developers to work on Moodle. * There are some very large deployments of Moodle, including the upcoming use of Moodle by the Open University of the UK, where they anticipate it being used by 200,000 students. Large organizations that use Moodle also help the project by devoting staff to maintain or improve Moodle, and Martin said that the Open University will be working on helping to maintain the "quiz" module, as well as funding directly some upcoming developments. * Martin wasn't sure he wanted to get into the fray over "Free Software" and "Open Source Software," but he admitted he uses the phrase "Open Source" himself. * Maintaining a project with some 20,000 scripts is a big job, but Martin still finds time each week to do some actual coding himself. He loves his job, and wishes that everyone would have something exciting to work on so that they want to jump out of bed each morning, like he does. -- 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 karisue at gmail.com Mon Oct 23 20:55:46 2006 From: karisue at gmail.com (Kari Matthews) Date: Mon, 23 Oct 2006 15:55:46 -0500 Subject: [K12OSN] stuck Message-ID: Hello, I am trying (still) to get my workstations to be fat LDAP clients.

Here are the settings we use on the Windows DHCP server: In this example, 192.168.0.10 is the K12LTSP server. This example also works across multiple subnets or VLANS, that is, the clients can be on an arbitrary subnet and still reach the K12LTSP server on another subnet. Depending, of course, on whether your network people allow them to talk to each other across subnets...This allows you to drop a K12LTSP server onto an already established network and share it with Windows/Mac PCs. A fully switched 100 Mb network with a Gigabit backbone is advised if you want to do more than just demo it for a few clients. Create a reservation for the mac address of each thin client. Define the server and kernel path: Option 017 192.168.0.10:/opt/ltsp/i386 Define the preferred boot server host name: Option 066 192.168.0.10 Define the bootfile: Option 067 /lts/pxe/pxelinux.0 The rest of the settings should be default for your network scope, and should not need to be changed. For reference, ours look like this: (The numbers have been changed to protect the guilty) Option 003 Router 192.168.0.1 Option 051 Lease 0x278d00 Option 006 DNS Servers 192.168.0.20, 192.168.0.21 Option 015 DNS Domain Name example.domain.com Option 044 WINS/NBNS Servers 192.168.0.11, 192.168.0.12 Option 046 WINS/NBT Node Type 0x8 Have fun, Sean Harbour Senior Network Engineer Northwest Regional ESD sharbour at nwresd.k12.or.us > Message: 6 > Date: Tue, 24 Oct 2006 07:45:15 -0700 > From: "john " > Subject: Re: [K12OSN] is it possible to use Windows DHCP server with > LTSP? > To: "Support list for open source software in schools." > > Message-ID: > <2be970b50610240745udb123c5pda614d425034a98b at mail.gmail.com> > Content-Type: text/plain; charset="iso-8859-1" > > Hi Guys, > > I am still working on this and I am glad that this thread happened.

When I called to talk to the director of networking, he said we could do whatever we wanted, as long as we didn't connect to the district network. Obviously, that makes the whole enterprise much less attractive. Below is a copy of an email I sent him outlining what I think are his concerns with the plan. If people who don't mind being quoted (and preferably have titles that central office folks would be impressed by) wouldn't mind taking a look and responding, I'd really appreciate it. If he responds with other issues, I'll let you know. Thanks, Todd ------------------------------------------------------------------------ Mr. Thompson, As I'm asking for advice from other people who use thin client labs in school districts around the country, I just want to make sure that I'm having them address the concerns that you have. Please take a look at the issues below and let me know if I've mischaracterized them or have forgotten any particular concerns. To be clear, we would be interested in creating a local network within the classroom which would connect to a single Linux server. The server would run all applications for the client machines. The clients would not be directly visible to or from the network as all network traffic would be handled by the server. As I understand it, your concerns are: 1. The server would not have been configured by Telecomm and you can not be sure that settings would not be changed in such a way that they would interfere with normal operation of the network. Problems could include address collisions with other machines on the network or the server attempting to usurp roles which other machines fill (attempting to serve DHCP to the network, trying to act as the school's Master Browser or something similar), both of which would cause havoc. 2. Because the server would not be Windows-based and is not part of the domain, you couldn't directly manage it and could not insure that it was properly configured. 3. The server would be routing traffic from the clients to the network and from the network back to the clients. Attaching a router to the network can always cause problems. 4. Troubleshooting network problems caused by non-managed computers on the network can be incredibly difficult. It is always time-consuming and often tricky because non-standard software can interact with your software in ways that make problems difficult to identify and resolve. If I've missed anything or haven't sufficiently identified the issues, please correct me. I'm hoping the people on the list I subscribe to can figure out ways to sufficiently address the issues so that you'd feel comfortable with a solution. To give you an idea of the economies we're talking about here, here's a breakdown of the cost to completely replace my lab: ~$3900 30 PXE-boot thin clients @ $129 each ~$2000 server built from parts, optimized as an app server: 4 GB ECC registered RAM, 2 dual-core Opteron processors, 2 SATA hard drives in a RAID array (assuming you eventually approve, we'd buy a second server to mirror the first as a backup in case of hardware failure) Because we'd be using Linux (all the software I use to teach programming is free and available in Linux versions), we wouldn't have to pay any licensing fees. In addition, because the thin clients do not run any of the applications, they don't become obsolete nearly as quickly as desktop machines. Buying a new server upgrades the entire lab and the thin clients can be used for 7 or 8 years instead of the 5 or 6 year lifetime we get with desktop machines. Compare this with the $15,000 price tag you mentioned for lowest-level desktops available with licenses and you can see why we're really hopeful that we can make this work.

The whole reason behind this is to allow our Development person to connect her Sony camera (i forget the exact model just now) to upload pictures to her /home. I had trouble doing this with CentOS 4.3 which is what our LTSP version is based on. This camera works great with FC5 out of the box. Right now I have the laptop authenticating to smbldap and mounting nfs to accommodate her. It would be nice if I could get this laptop to be functional outside of our local environment. > different design and it doesn't work that way. Changing your authentication > realm, at login, on the fly is the biggest obstacle. Hmmm...surprising tht the open source would be less flexible in this way. I think I'll just leave ldap out of it and try this: make some "local-user-accounts" and "nfs-user-accounts" in /etc/passwd and in /etc/fstab mount /home/nfs-user1 on nfs. If the laptop is outside our environment the failing nfs mount of that user shouldn't be big deal. Sound feasible?

Another key feature is that they consume only 5W of power, so installing 24 computers in the room did not require any electrical rewiring. Tables are back to back. A single power and network cable are brought over the floor under cable cover which is duct taped to the floor. Each table has a small switch (5 to 8 port) and power strips to distribute power under the table.

I want to use my old one as a web server (a massive upgrade hardwarewise from what I'm running now). I was going to just reinstall the thing from scratch to get the latest/greatest everything, but time has become an issue, not to mention fatigue from configuring servers. I've been running the thing as a LAMP server on the side, so it's almost exactly what I need already. Can someone recommend a way to "convert" this thing back to straight FC? Can I "yum remove" certain things, disable certain repos and turn off a few services? I would like to, at that point, be able to run "yum upgrade" and get to pretty much stock FC6 without repo conflicts. It's at k12LTSP 4.2.2 right now. Any thoughts? [more crickets?] Thanks a bunch, as usual. ck From sysadmin at handsworth.bham.sch.uk Wed Oct 25 08:12:16 2006 From: sysadmin at handsworth.bham.sch.uk (Martin Woolley) Date: Wed, 25 Oct 2006 09:12:16 +0100 Subject: [K12OSN] Retiring a K12LTSP server (back to just FC6 LAMP/Samba) In-Reply-To: <453F056B.80809@snarlnet.com> References: <453F056B.80809@snarlnet.com> Message-ID: <200610250912.16355.sysadmin@handsworth.bham.sch.uk> On Wednesday 25 Oct 2006 07:34, Carl Keil wrote: > Can someone recommend a way to "convert" this thing back to straight > FC?

By the time you've worked out want you don't need on a web server (Openoffice, Graphics, Sound, Games, Edutainment, LTSP, etc) and uninstalled it, and worked out what you do need (Apache) and what you might need (Mod-Perl, Mod-Python, MySQL, Postgresql, etc), I think that you could have reinstalled it from scratch. I recently re-installed our FC5 LAMP server in a couple of hours (hardware replacement just like yours) and it is humming away nicely. I lost no sleep wondering if I'd forgotten something when it went live. -- Regards Martin Woolley ICT Support Handsworth Grammar School Isis Astarte Diana Hecate Demeter Kali Inanna From petre at maltzen.net Wed Oct 25 13:15:47 2006 From: petre at maltzen.net (Petre Scheie) Date: Wed, 25 Oct 2006 08:15:47 -0500 Subject: [K12OSN] Responses to the central office In-Reply-To: <1161724867.21604.73.camel@200-8143-202-01.Jefferson.ketsds.net> References: <403593359CA56C4CAE1F8F4F00DCFE7D0320DD27@MAILBE2.westat.com> <1161724867.21604.73.camel@200-8143-202-01.Jefferson.ketsds.net> Message-ID: <453F6383.8000809@maltzen.net> A couple of observations: To guard against any of the four potential problems listed that Mr. Thompson fears, he should simply be prepared to disconnect your link from the rest of the school any time he sees a problem that he thinks your setup might be causing. If you are indeed the source of the problem, the problem should disappear. Insist that he inform you any time this happens (which should be the case anyway), and keep track. Make sure you have the support of your principal. What will happen is that if they do cut you off at some point, it will likely be because of misdiagnosis of the problem (assuming you aren't trying to do anything exotic at your end) because the kind of problems listed just don't come up. Arguably, if I understand your setup, it's no different than how the local ISP feels about people putting in a Linksys router at home so they can connect more than one computer to the internet. In the early days, some ISPs had policies prohibiting people from doing that for the same kind of fears. As it turns out, it isn't really an issue, and I don't know of any ISPs that still have such policies. I suspect that Mr. Thompson has such a router in his home and would dismiss his ISP's concerns about people having routers in their homes. Second thought: I would speculate you'll get more than 7 or 8 years out of your thin clients; more like ten, perhaps more.

Here at the Library our computers are in table clusters with power and eithernet cabling running underground from the wiring closets to the tables. Of course the floorplan was designed that way when the new building was constructed. The old building was renovated to meet the same conditions but that meant a jackhammer to carve out a trench to lay the pipes. I don't think you want to go that route :) I think for simplicity sake and avoidance of trip hazards, setting up around the perimiter of the room would be a good solution. Maybe you can do the same as the 1st paragraph but turn the computers around to face the teacher and move the desks away from the wall to create room to walk around and sit. You can then snake the power and lan cabling from one side all the way to the other end and have only one area exposed as a trip hazard. Home Depot sell a 25 ft power cord with connections every 3-4 ft. We use those in our laptop lab.

It was a real win-win situation: the company is paying to have a whole bunch of old equipment hauled off, and I reduced the cost of that substantially by taking the laptops. At the same time, the laptops are great as thin clients because they have built-in ethernet, PXE boot, are silent (because we took the hard drives out since we don't need them), take less space than desktops, use less power, and only require one electrical outlet. My point is that I suspect that there are many opportunities for this kind of win-win arrangement. I suggest inquiring with local businesses as to whether they have any such pools of old laptops, either asking them directly or through the students' parents who are employees of such companies. In my case, I just got lucky and happened to ask about the laptops right before they were hauled off. Petre sonjag at comcast.net wrote: > I'm thrilled that I can actually contribute to this list!!

Not only does it show that you understand their concerns but also researched the issues and have come up with possible solutions. They'll probably still say no. You might want to offer to train one of their techs on Linux. Even without Internet access you can still do many things with it. Perhaps later on down the road you can convince them to allow you to hook-up on a "trial" basis.

Maybe he feels like it threatens something he's doing, or he fears it will be more work for him, or that he'd have to learn something new. With the board behind you, it shouldn't be an issue, but as it's better to win the guy over than go over his head, I've posted some arguments for you below: > 1. The server would not have been configured by Telecomm... It would be trivial for him to go over the configuration with you before plugging it in to the network. It should be agreeable to both of you to say it will not be connected until it's set up to mutual satisfaction. It would not usurp any Windows network browsing functions unless you were running Samba in such a configuration. It would also not put out DCHP on the school network interface unless you configured it that way. > 2. Because the server would not be Windows-based... See above regarding config review. If you're comfortable with it, you could always share the root password with him. If it's because he has little or no Unix experience, you could always take him through a tour of the system and configs. > 3. The server would be routing traffic from the clients to the network... You are only hooking one machine to the network rather than 30. That's less traffic and less consumed bandwidth. I once used a simple Slackware box to firewall our office network using only iptables at an ISP I used to work for, and it caused zero problems. (By the way, it also did DHCP for our office network and didn't interfere in the slightest with our dial-up gear or other equipment on the network.) > 4. Troubleshooting network problems caused by non-managed computers... Petre's argument works here -- let him unplug it if he fears it's causing collisions or other problems. If he's running managed switches, it should also be trivial to track down problems or shut off connectivity remotely. Again, it seems to me he's got some other concerns he's not sharing or is just plain stubborn as these are minor concerns at best. It could also be simple fear of the unknown, or maybe he's bought into some Linux FUD. Just an opinion based purely on this email. If you want to throw some credentials at him, I've been a technology director for two different school districts and a systems administrator for an ISP. I'm also Linux+ certified. Good luck! And good on ya for trying to win him over rather than siccing the administration or the school board on him.

I am trying to figure out how to best implement thin clients in a classroom and not a lab. i have been searching the net for some floor plans that others may be using, but cannot find much. i want to make these permanent in the classroom, and try to minimize distraction from an LCD panel on the desk, maybe under the desk with glass top? Currently our desks are individual desks, some that the top flips open, some not. I am also trying to figure out the bast way to get ethernet jacks and power to the desks or cluster of desk. I have toyed with possibly bunlding the ehternet and extension cords and rolling them out on the floor, but i do not know if there would be interferance from the power cords and plus it doesnt sound like a good permanent solution.

By the time you've worked out want you don't need on a web server (Openoffice, Graphics, Sound, Games, Edutainment, LTSP, etc) and uninstalled it, and worked out what you do need (Apache) and what you might need (Mod-Perl, Mod-Python, MySQL, Postgresql, etc), I think that you could have reinstalled it from scratch.

You push a button, and they silently rise from the desktop. There's room in the monitor compartment for a keyboard and mouse. The monitor is proteced in front and back by the desk. Also, there are conduits on the sides that you can run cables through when the desk are side by side so no cables run across the floor. I can't remember the exact figure, but it was going to be over $12k to get 25 of them for my classroom last year. I currently have my computers around the outside walls of the room. I't makes for a pretty packed room. I only have room for 24 students in a classroom setting, and 20 in a computer lab setting. At these numbers its incredibly packed. And of course, every semester, I must go to the principal and remind him of these numbers after they pack 32 kids in my Algebra class. Right now, I have to live with 28 in my algebra class, and I have kids squeezing onto the ends of tables. My point is, make sure that class sizes and room size won't be an issue if you're planning on doing both a lab and classroom in the same room. I've got a panoramic shot of the computers in my room. This was tanek from the back corner of the room behind my desk. I now also have a bank of 3 more thin clients on the far right between my desk and that door you can see. Hopefully this will give you an idea (warning, it's 2.7mb): http://www.keokukhigh.net/~ericbrow/pics/classroom.jpg Good luck.

However for my classrooms, because of the different projects and management of students there, we set them up as "pods" in the room of 4 to 6 computers (2 to 3 tables.) The teachers who have these rooms prefer it. One of the rooms I put this in is an LA room. She has 5 pods of 4 computers, none of which are along the outside walls. She uses the edges of the room to create reading centers, and also houses her library and her conference area on the outside of the room. The pods work well for peer conferencing. The other room is a science room, and she has 4 pods of 6 computers. She prefers the pods because she has small groups working together as well as labs (she covers the computer tables with vinyl tablecloths) that require her to have larger deskspace. She stores her equipment and books around the outside of the room. This is a science room without sinks or science countertops, and she doesn't use many liquids. My 7th and 8th grade science room has built in counters and sinks with running water, so computer tables were impractical. He preferred to have 6 computers (he has 6 science groups per class), which we mounted to the wall over his lab counter. We purchased monitor mounting kits, and hung the terminal from one of those plastic picture hangers that have double stick tape for wall mounting. Since these do have water, so it was nice to get them off the countertop completely. We did discuss the inability to see what everystudent is doing from one vantage point, but decided that we would forego this feature because setting them up this way works better for the reasons listed above.

Also a GUI control, but has more options. There's also tools like fwbuilder if you need even more control. Or you can always write a iptables script yourself.

It turned out that one of the switch uplinks between the clients and K12LTSP server was over 100 meters (328 feet) long. I had to, unfortunately, force that link to 10/F to get it to work. It only affects five of that site's thirty clients, so it's not much of a problem. Also, check all Ethernet connections between the server and clients to ensure you don't have a duplex mismatch. That will also cause funny communications problems. Also, check patch cable integrity by swapping them, and, if you have the expertise, plug in the ol' sniffer and watch the packet-level traffic for clues. Good luck.

As long as you leave wheelchair access on the floor level (with some way to get a wheelchair up to a monitor and to a writing surface), you should be able to comply. We host our county Deaf/Hard of Hearing group, as well as the physically disabled group, so it's not unusual to have a class with two wheelchair-bound kids and a Deaf kid or two (with interpreter). Needless to say, some classes aren't big enough for that, even without risers.

You have to tweak the bootfile parameter for etherboot systems. I used it to hand out DHCP across multiple subnets, our central router does a DHCP/BOOTP relay to the IP address of the dhcp server. Global Options: Option Name Vendor Value Class 006 DNS Servers Standard 10.142.1.7, 10.142.1.11 None 015 DNS Domain Name Standard hhp.hhprep.org None 017 Root Path Standard 192.168.0.5:/opt/ltsp/i386 None 044 WINS/NBNS Servers Standard 10.142.1.7, 10.142.1.11 None 046 WINS/NBT Node Type Standard 0x8 None 066 Boot Server Host Name Standard discovery.media.local None 067 Bootfile Name Standard /lts/pxe/pxelinux.0 None You really don't need to worry about the WINS stuff. Also, I'm transitioning my domains, so I have some stuff on the old "MEDIA.LOCAL", and some on the new "HHP.HHPREP.ORG" so it looks a little wonky. Within each subnet config, I add the default gateway/router. That's it. Remember, this config is for PXE bootable images. Change the Bootfile name to the Etherboot one if you need that as the default. Windows DHCP doesn't do the nice if/else selection of Bootfiles.... I personally am going to redo all my thin-client hd installs and setup those etherboot images to boot PXE. Hope this helps.

Is this a generic netboot parameter? 2) If windows pads the root path with 000 do I need a symlink on my linux server from a directory called /opt/ltsp/i386000 > /opt/ltsp/i386 3) is the string for option 211 always tftp? 4) I glibly said I had the other boot parameters (ip, subnet mask, gateway) correctly set, because those parameters are the defaults handed over by the dhcp server on that scope. As I think about it I think I should be using an ip, subnet mask, and gateway consistent with that of the ltsp server (which sits on a different subnet than my test client. So if my LTSP server is 10.114.0.105/16 my clients should be 10.114.0.x/16 and use 10.114.0.105 as the gateway. Err, but perhaps I am getting myself in a muddle here. Thanks again.

That is a limitation of SMB. You can mount shares, but not subfolders of shares. I usually work around this by mounting the entire share with the user's credentials, in a hidden subfolder of his/her homedir (like ~/.Windows), and then symlink ~/Windows -> ~/.Windows/$USER Ugly, but functional, when you don't have admin rights to the ADS server. -Gadi On Wed, 2006-10-25 at 09:44 -0700, john wrote: > Hi all, > > Does anyone know if its possible to mount a user directory nested > inside of a shared directory with pam_mount? > > I can mount //share but not //share/user_name using wildcards.

Second, in most cases the LTSP server with two interfaces doesn't usually require that packet forwarding be turned on at all (that is no packets get forwarded from "inside" to "outside" interfaces at all), that is the difference between a dual-homed host and a router. If your interfaces are on the same LAN, then disregard this. Assuming your interfaces are on different LANs, what makes you believe that dhcp broadcasts are being forwarded? My guess is that you are seeing broadcast dhcp requests from the "other LAN" that your external inteface is on and not from your X terminals on the "inside" LAN. > > 2) The GUI firewall control leaves a lot to be desired.

Keeping it off the district network: Fine, we found many classrooms had two independent Cat5 wires going to the room, so we used one for the district network to the teacher's PC (and any windows PCs required for special purposes) and the other one to feed the K12LTSP servers in each class. We fed the Internet to the K12LTSP servers via a business class cable modem (6-10 Mbps, $100/month) connected to Squidgard/Dansguardian firewall in IDF. Ultimately, the PTA paid $9000 to run 40 new Cat6 ports from three switches, one to each room and some in hallways (for laptop carts), but finally the district acquiesced and said it would do a pilot of K12LTSP. The new wiring was timely, as they wanted to do a centralized server model, which requires Gbit/sec to each classroom. But if they hadn't agreed to the pilot, we could have had two independent networks, one for teachers and admin PCs fed by district Internet, and the other fed by cable modem to all the K12LTSP servers and student thin clients. 2. Concern for messing up teacher IP addresses: A district technician came in one day early on in our deployment and rewired a server and it began happily handing out IP addresses to the teacher's PCs, shutting off their Internet access. That was when the district finally realized that we had moved ahead with our deployment. Solution: hardcode the MAC addresses of each client to an IP address from each server. Then, even if miswired, the LTSP server can't give IP addresses to the win PCs. 3. Managing server/configuration: Linux allows secure login to manage each server from anywhere in the network. With Webmin, it's GUI and easy. And you can manage more Linux servers more effectively from a single location than with Windows. 4. Agree with previous posts on routers as commonplace in home and business networks now. Point out that his home Cable/DSL router is most likely running Linux. 5. Troubleshooting network problems caused by non-managed computers on the network can be incredibly difficult: Reality, from all of this groups' collective experience I'm sure, is that it is *easier* to manage, and the Linux computers *are* managed, but by built-in capabilities instead of purchased software. Built in Linux management capabilities exceed those of LANDesk currently, e.g., especially given that you can manage all those old Win 95/98 thin clients now, whereas you couldn't before using proprietary tools. Point out that the experience of others is that managing the K12LTSP servers has proved to be *significantly* less time consuming than Windows platforms. Regarding cost benefits, note the following: Thin clients running Open Source Software lower the total cost of ownership of technology for schools in the following ways: 1. Lower acquistion cost by at least 50%, typically more. Software cost is zero. 2. Lower operational cost via reduced electricity requirements: 1/5 Wattage of normal PC, plus smaller form factor: you can fit twice the number of thin clients on the same table. Space and electricity were the final challenges we had at Brandon as we moved to a 2:1 classroom model. 4. Lower support cost: you only manage the servers, and one server can run up to 100 thin clients. Linux admin can manage more PCs than equivalent Windows admin. 5. Lower cost of retirement: thin clients weigh less than 1/5 of normal PCs and schools have to pay by the pound to have them hauled off. Plus, you can put dozens of modern educational software applications in front of your students for free, and can burn CDs with the software for the kids to take home and use there. Open Source Software is free to use and distribute as one desires. Figure out the cost of providing copies of MS office for every home with a PC, let alone Adobe Photoshop, a 3-D rendering package like the GIMP (doesn't exist, and by the way most Hollywood animation outfits have switched to Linux/GIMP), etc...

Yep, that's me, and my co-conspirator is William Fragakis, who also posts to this list. I am so passionate now about Open Source I formed a non-profit (GOSEF) and am taking the message statewide and to business, community and political leaders. And Jim Kinney, also a K12OSN'er, is the Linux consultant I recommended to APS who is pushing the LTSP envelope by designing and implementing a centralized server model for the APS pilot, using servers that feed over 100 clients and Gigabit wiring throughout. I think this is what Eric did in Oregon too.

Mostly been just listening for the last month or so. I am lucky enough to have Eric Harrison 15 miles from me, so he has been an invaluable asset. In about 6 hours of his time he has set up our network, installed the software, streamlined our two new Dell servers and made about 30 HP circa 1998 computer work as terminals, and shown one total newbie the basics of how to run K12LTSP. Just wanted to ask a few very trivial questions. (I am sure I will ask more over the course of the next year) 1. How do you allow permissions for specific programs per user. (we are using LDAP for authentication) For example: I would love to give every teacher the ability to use the FLK teacher tool, but obviously not students. 2. Is there a C compiler that comes stock with K12LTSP?

The issues are space, cabling, classroom non-PC use, and cost. I've found there are three basic layouts: 1) Standard tables around the perimeter, either long side against the wall to save classroom interior space, or short side against the wall so you can put three LCDs and small thin clients on each long side of the table for 6 clients per table. Short keyboards help a lot in the latter configuration for 6' tables. Many of our teachers prefer to use the half disk or semicircle tables against the walls so that students can't easily look onto a neighbor's work, but you can also put divider slabs between each station (a piece of hardboard perpendicularly stuck in a block of hardwood would work). 2) Tables in parallel rows, short sides against one wall for aisle and teacher desk on opposite wall, or V configuration with aisle in the middle. Common for computer labs, but leaves no interior space for non-PC activities. 3) Clusters of 4-6 standard student desks in the interior of the room, often preferred in normal classrooms. Whereas cabling/power are straightforward for options 1) and 2), for the cluster option, unless you have power outlets imbedded in the floors throughout the rooms, it's a major issue; even with rugs, the kids will also trip on them because they refuse to lift their feet when walking. Some new wrinkles I've thought of: 1) For the tables on the perimeter, long side against the wall, if you use LCD monitors with new, small thin clients, standard 6' computer tables are twice as wide as they need to be. Use half-width tables instead, and you'll save interior space. We're also going to use half width tables in the more narrow hallways for our remaining 'hallway laptop carts' which in this case are fixed tables since we've noticed the existing carts aren't being moved. 3) In addition to the cabling issue with clustering, solutions like the Bretford Connections SmartDeck Work Center are very pricey ($600+) and don't include a place to put books, pencils, etc like standard student desks. A cheaper solution is to use standard desks already in the classroom and find a solution to getting a network and power cable to them, hopefully w/o tripping. Is there a solution other than the rubber humped strip/ductape on the floor approach to getting power and network cable to clusters of desks in the middle of a classroom?

I can be helpful. You can create groups and provide permission on a group basis. I'm using Ubuntu, which has adduser and addgroup tools. K12LTSP may, too. Check for these by typing man adduser man addgroup If they don't exist, you have to use useradd and groupadd, which are slightly pickier. To set the group of a program, use the chgrp command chgrp teachers some-program would put some-program in the teachers group. To give everyone in that group permission to run it, use the chmod command chmod g=xr some-program chmod o-xrw some-program The first command says that members of the program's (g)roup have e(x)ecute and (r)ead permission. (The equal sign sets the permission.) The second says all (o)ther users have no permissions. (The minus sign takes away permission, and in addition to execute and read, makes sure that other users cannot (w)rite over the program.)

I verified that this affects only the selected set (group, in this case). I "chmod g=w file", and group permissions were set to write-only, while clearing the read and exec bits. Thanks for the tip.

When I want to restrict a program to a certain group. For example only allow a certain group to run firefox. 1) create a new group called firefox (system-config-users) 2) Add firefox group to all who you wish permission to run it 3) change group of firefox binary to firefox (chgrp firefox /usr/bin/firefox) 4) change permission of firefox binary (chmod 754 /usr/bin/firefox) As for Fl_teachertool see my web page instruction #5 Setting up to run with sudo http://www3.telus.net/public/robark/Fl_TeacherTool/ oh and BTW the path to the binary is /usr/sbin/fl_teachertool disregard the /local/ in the path 2.

To keep people from running the installed firefox you'll also need to remove the 'other' read permission (chmod 750) or they can just cp the binary elsewhere and execute that. Also, in the particular case of firefox, /usr/bin/firefox is usually a shell script or a symlink to a shell script in which case it can still be "executed" even without execute permission by running 'bash /usr/bin/firefox'. To truly restrict execution to a specific group you'll need to chmod 750 the real executable (/usr/lib/firefox*/firefox-bin). --Shahms From toddobryan at mac.com Wed Oct 25 22:27:16 2006 From: toddobryan at mac.com (Todd O'Bryan) Date: Wed, 25 Oct 2006 18:27:16 -0400 Subject: [K12OSN] Basic Questions In-Reply-To: <453FDD33.8040407@corbett.k12.or.us> References: <453FDD33.8040407@corbett.k12.or.us> Message-ID: <1161815237.1114.69.camel@200-8143-202-01.Jefferson.ketsds.net> On Wed, 2006-10-25 at 14:54 -0700, Derek Jaques wrote: > 2.

I think on of the big scares for tech admin and the K12LTSP setup is really that now the have students sitting at computers that THEY have not locked down. So you need to show them that there is no IM software, no way to get to those porn sites, no games, what ever it is that your school does to lock down the student experience. In one of the schools I had set up an LTSP server, I had a small lab with 10 terminals. The Tech Dept (1 guy -- yes small school) was happy to let me do it, but he had to know that the same "rules" would apply to kids in my lab that applied to all the other labs. This went so far as I had to lock down the kids wallpaper/icon/windowing themes.

The idea is to provide each student with an area where they can keep their presentations, and on the day of the event (held at a local university) we take the server, set up 20-30 laptops connected via a couple of switches, and have the students download their presentations when the judges call their name. So far I've created the names of the schools in the home directory (home/schoolA, schoolB, etc) and using webmin and an algorithm for six character unique passwords, I've batched-created S(chool)Amascot1, SAmascot2, SAmascot3 (see http://links.episd.org/users2.txt for a working Webmin batch file example) and they reside in /home/schoolA/SAmascot1, /home/SchoolA/SAmascot2... The end result is that each participating student has an area in her/his school's folder, and access it with a unique login and a unique password. What I am having a hard time doing is making these files be accessible via a firefox ftp call: ftp://SAmascot1:A1B2C3 at I.P.Address needs to take that user to her/his folder, w/o access to any other schools/folders. Each school folder was chmoded (with the sticky bit on) to 700, and each folder (home account) inside the school's folder is chmoded to 770 w/o sticky bit. This works ok with ssh, but that's it. I can't get FTP started (vsftpd generates one error after the next) - tried nfs and samba shares, w/o much success either... If it was your setup, how would you configure it?

If AOD contains the objectclasses and attributes that are included in the Openldap "nis.schema" it should be possible for Linux to use it. A further potential issue is encryption. Does AOD use TLS or Kerberos? If so your Linux hosts will need to use it too. The LDAP authentication in Linux is pretty flexible; if it weren't it couldn't use Active Directory. It may take some re-mapping of attributes, but it should be doable. -- "History doesn't repeat itself; at best it rhymes." - Mark Twain | John Lucas MrJohnLucas at gmail.com | | St. Thomas, VI 00802 http://mrjohnlucas.googlepages.com/ | | 18.3?N, 65?W AST (UTC-4) | From mrjohnlucas at gmail.com Thu Oct 26 10:57:28 2006 From: mrjohnlucas at gmail.com (John Lucas) Date: Thu, 26 Oct 2006 06:57:28 -0400 Subject: [K12OSN] FC5 now legacy?

I would also add you can use Konqueror and the fish protocol: fish://ipaddress Think of it as a front end for scp/sftp. This way they can open a browser and be in a familiar interface, and it will prompt them for their user name and password. Again, all you need on the server is for SSH to be running. You can use a split view in the window to get a two-pane view similar to a typical FTP/SCP GUI. Of course, this assumes you've got KDE. I've not had enough hands-on with K12LTSP (yet) to know for a fact if this will work.

The summary is that there has not been enough space to host CDs and DVDs. Adding DVDs requires an additional 7G per release. CDs are more important than DVDs in that DVD drives will read CDs, but CD drives won't read DVDs. So CD-only it has been. I have plenty of free space on the new server, so I'll most likely make a DVD for K12LTSP 6.0.0. -Eric From lists.john at gmail.com Thu Oct 26 15:37:16 2006 From: lists.john at gmail.com (john ) Date: Thu, 26 Oct 2006 08:37:16 -0700 Subject: [K12OSN] Is it possible to mount user shares with pam_mount?

I would like to mount the drives using CIFS but the mount fails when I try. I haven't figured out if Ubuntu 6.06 is compiled without CIFS support yet, or not. I guess one other problem for me, right now, is that my shares don't unmount on logout, which means I get lots of persistant connections. I wonder if I should end up mounting my shares from fstab and give up the whole pam_mount approach.

Then each user has to put their files in ~/public_html (or whatever subdirectory you designate). Then the user just points FF at http://server:userid/public_html to see the files. By default, this means everyone's files are available to everyone, but read only. If that's not acceptable, you could look at putting a .htaccess file in ~/public_html which would trigger a prompt for an ID & PW to gain access. And of course, you have to setup Apache to work with the .htaccess files including creating a file that has all the IDs & PWs, but it's not very hard.

For vsftpd, you'll want to review your configuration there, too. First I assume you've got the daemon running, but sometimes the defaults are locked down. I'm using vsftpd on a Slackware box and I'm able to connect with Firefox just fine. Check these settings: local_enable=YES If this is NO, then nobody can log in. I think the default was NO in Slackware. write_enable=YES Probably only needed if they're uploading files back to the box. connect_from_port_20=YES I don't recall ever having to change this, but can't hurt in case that's what Firefox is looking for... I would bet the first is the culprit. The vs in vsftpd is "very secure" so it's very likely it's locked down out of the box. Remember to restart the service/daemon if you make any changes! Are you trying to avoid having them download extra software? Another simple solution would be to use WinSCP (http://winscp.net/eng/index.php) on the Windows laptops and maybe Fugu (http://rsug.itd.umich.edu/software/fugu/) for the Macs.

I wanted to extend an invitation to everyone on this mailing list to speak at this FOSS and Education gathering. Last year, we had an incredible group of speakers from all over the world and I am hoping we can do even better this year. If you have ever wanted to travel to Sydney, this could be your chance! The details and call for presentations at the mini-conference can be viewed at: http://www.fossed.org/lca07/index.html The general conference website is: http://lca2007.linux.org.au/ Unfortunately, there is still no money available to assist with travel but the good news is that speakers no longer need register for the main conference - though you are encouraged to do so! If you have recommendations for other people that I should invite, please let me know. Looking forward to hearing from you. Thanks, Bryant Patten White Nitro, LLC ______________ About linux.conf.au 2007 linux.conf.au is Australia's annual technical conference for the Open Source and Free Software developer community.

I've been thinking that a lot of the capacity questions that get asked on this list amount to people asking: "how many people can use a single computer at the same time?" Surprisingly the answer seems to be somewhere between 30-200 depending on setup/configuration/use. It's kindof mindblowing and some people might never accept it as true. You could, honestly, tell the telecom folks that you're installing a single computer for the lab to share. They will still have all the headaches of the multiple *users* that will be using the computer, but there is only one OS/Hard Drive (or Array), config, IP, etc. that needs to be managed. One place where viruses could infect, one set of logs, etc. All the users will fall under existing rules, and this single computer can too. All the "workstations" don't have a hard drive, external IP, etc. The thing isn't a router, because the terminals aren't computers. They're "dumb". They don't store a state of any kind. It's one computer with a classroom of users. You're just using IP/Ethernet technology on the second NIC to attach the monitors/keyboards/mice. You wouldn't be lying and it might be a way to think about it that makes the tech guys more comfortable and understanding of what's going on. Is this too cute and semantic of an argument? This is exactly how I think of K12LTSP. It's the whole reason I'm installing thin clients throughout my home, so I only have to spend my valuable time maintaining/watching/upgrading one "computer" to serve all the people/rooms of my house. I hope that helps. ck From hick518 at yahoo.com Thu Oct 26 22:25:29 2006 From: hick518 at yahoo.com (Rob Owens) Date: Thu, 26 Oct 2006 15:25:29 -0700 (PDT) Subject: [K12OSN] Creating a repository in a K12LTSP server In-Reply-To: <1161832030.3318.33.camel@HodsonNet1> Message-ID: <20061026222529.69828.qmail@web32812.mail.mud.yahoo.com> I think you mean that the laptops will act as thin clients....

I use a small utility on the Windows clients, called DaemonTools. It acts as a physical, local cdrom/dvd drive and mounts ISO (and a swathe of other cd-image formats) images from a central fileserver. To create the cd-images I use Nero Express, Graveman or mkisofs.

Then they call the file with: http://server.address.com/~username/file.ppt No worries with FTP! You can also set up samba as a share-level device and add the users to it. Samba will allow easy windows connectivity to their home directory with: (from a winders computer) START RUN \\ip.ad.dr.es.ss\homes and it will oen their home directory. If the computers they are saving from are WindersXP it will present them with a login screen for their username and password. You won;t have to worry about which school or nothing. Only their usernames in winders and samba. I have a script that I wrote that adds them to linux and samba at the same time from the commandline and could likely be used with a text file using one of the methods that allows you to parse a text file and pull data one line at a time and do something with it. I can't remember but it is something like for a$ in /path/to/file/file.txt do command exit I am sure there are others that can expand that and make it actually work. . . Anyway, that might be easier to do than the by the school thing since they would use usernames rather than location. . .

I use a small utility on the Windows clients, called DaemonTools. It acts as a physical, local cdrom/dvd drive and mounts ISO (and a swathe of other cd-image formats) images from a central fileserver. To create the cd-images I use Nero Express, Graveman or mkisofs.

To avoid such situations at our K12LTSP sites, rather than having students double-click an icon to open its program, we train them to right-click the icon, then select "Open" from the floating menu that appears. It will still take some seconds for the program to start, but the students know their request has been sent and they are to wait rather than retrying.

Well, keeping in mind that I'm NOT a video expert, I was satisfied using "kivo" to edit my son's football games. I _did_ find it to be unreliable at grabbing video directly from the camera, so I'd use dvgrab to download the video in handy 1 gig chunks (less than 5 minutes' worth), then use kivo to assemble those chunks, edit out the unimportant stuff, and output the video in Mpeg2 format, suitable for burning on DVDs to send to college coaches.

(I have LTSP running in the home). 1 of my clients is a "dual boot" LTSP client or Windows 98 box. The windows 98 box is so my kids can play their PC kids games. I have a SAMBA share that holds all the CD-ROM isos. The windows boxes mount it as M: . Then they have a number of shortcuts on the desktop that mount the ISO via DaemonTools.

If you attempted to do the same thing on a terminal, which only gets a share of the processing power.

I have heard that the LTSP crew is working on something that will make the server aware of the capability of the client, and will push intensive jobs to a client that is capable of handling it.

In fact, it even had problems (choppy video) running directly on the computer, until I replaced the built-in video with an add-on video card. > you've ever done video editing on a Windows computer, you'll know that > it is very processor intensive.

This is the command it runs to match Usernames/IP addresses: netstat -t -e -n | grep :6000 | grep -w ESTABLISHED |\ sed -e 's/:/ /g' | awk '{print $9,$6}' | sort | uniq If I'm reading that correctly, it does not care whether the source or destination is established on port 6000.

Possibly a cable modem/router, or a windows box, or another linux box serving up DHCP to the network. The first time you boot the client, the "other" dhcp server is slow to respond, probably because it's swapped out or something. So, the first request is the 'wakeup call', and by the time you reboot the thin client, the "other" dhcp server is ready to answer requests, and it's beating your LTSP dhcp server to the punch. That's my guess anyway. To really test it, make sure you completely isolate your LTSP server and your client. Make sure there's nothing else on that physical network, and try booting the client. Also, any chance you have both eth0 and eth1 of the server plugged into the same network switch?

And if there is no managed switch, you could install an IPCop firewall between the LTSP server and the rest of the network. It's got a web interface and you can give him the admin password for it. This will allow him to block traffic to/from your LTSP server as needed. IPCop is based on Linux, and is free.

The idea is that the kids can click on the icon to open a view of their home directory on the remote file server, and drag files in and out of there. Ideally, it would prompt for an ID & PW, but we could manage public keys over ssh if necessary. What I can't figure out is what command the icon should call when the user clicks on it. Trying to setup a generic link in gnome, using environment variables like $USER and $HOME doesn't work because Gnome doesn't seem to understand those and just treats them as literal strings. I can call sshfs with environment variables, but that just mounts the remote directory. I supposed I could create a script that calls sshfs, and once mounted, calls Nautilus's file manager pointed at the mountpoint; what's the syntax for that? Or is there a better way?

Thanks. For the record, the --no-desktop isn't necessary in my case since I'm already running the gnome desktop. The full story on what I did was create this script and then create a launcher that calls it: sshfs remotesrv: $HOME/.remote nautilus $HOME/.remote I made the mountpoint a hidden directory to keep people from accidently deleting it or saving files under it when the remote host wasn't mounted. Then I put fusermount -u $HOME/.remote in /etc/gdm/PostSession/Default to unmount it when the user logs out. BTW, there's also a Default.ltsp in that directory, put putting the fusermount in that didn't work.

And if there is no managed switch, you could install an IPCop firewall between the LTSP server and the rest of the network. It's got a web interface and you can give him the admin password for it. This will allow him to block traffic to/from your LTSP server as needed. IPCop is based on Linux, and is free. I know someone who uses it for his company's main firewall, and it's running on an old Pentium 2. -Rob ________________________________________________________________________ ____________ Access over 1 million songs - Yahoo!

We're using ZABBIX and I love it. No where near as much work as setting up Nagios and it does all you're listing here: SNMP, custom probes, historical graphs, notifications. I recommend everyone to check it out (http://www.zabbix.com/). According to their website it scales pretty well too, they have tested ZABBIX with 5000 monitored devices and services.

Actually, that's one of the touted benefits of the NX protocol, that it can strip and compress X traffic down to low-bandwidth links like dial-up and still give decent performance. Thus, if your server has a T1 upload link, you ought to be able to get ~20+ freenx sessions going, assuming the server can handle the load. Caveat: I haven't tried this. It seems several people have been thinking along the lines of providing access to the server to students at home. Since the server isn't really in use after hours, it would seem to be feasible.

Message-ID: Well, one reason I want to do this with NX client is to keep the consentience of office programs. Also, NX client compress X over ssh which improves performance and security over dialup and broadband. The students use what ever comes with their pc from computer manufacturer, so I have to fight with Corel, Microsoft Works, and other word processing programs. Plus, there is no confusion where the student saves his work floppy, pen drive, or home drive. Then I do not have to deal with bad floppies and pen drives. Another thing using the NX client might help a student if his computer is infected with a lot of virus or spyware. The NX Client might run good enough to allow him to work on school projects were the student might not be able to run a word processor or spreadsheet program in the computers current infected state. My biggest concern is someone compromising a student account using the terminal server to explorer the network for more targets to hack. That is one thing I would have to minimize before letting students connect from home. -Glenn -----Original Message----- From: Ramon [mailto:ramonklown at pop.com.br] Sent: Monday, October 30, 2006 9:19 AM To: Support list for open source software in schools.

One thing zabbix doesn't appear to do (yet) is auto-discovery. You can give opennms a set of network ranges and it will auto-probe them for a configurable set of services and start monitoring what it finds. Likewise you can give snmp options for ranges and it will start collecting a default set of information from the hosts that respond - and it knows to collapse multiple interfaces found with snmp into a single 'node'. It defaults to a summarized view that is nice for a large set of machines. Both products seem to have active development so it's hard to tell which will end up with more features. -- Les Mikesell les at futuresource.com From les at futuresource.com Mon Oct 30 21:08:54 2006 From: les at futuresource.com (Les Mikesell) Date: Mon, 30 Oct 2006 15:08:54 -0600 Subject: [K12OSN] Re: build your own thin client In-Reply-To: <97E96531BC48B6439B5F81F6F24B92945E0334@rbexfe.rb60.local> References: <97E96531BC48B6439B5F81F6F24B92945E0334@rbexfe.rb60.local> Message-ID: <1162242534.28312.52.camel@moola.futuresource.com> On Mon, 2006-10-30 at 12:58 -0600, Mike Oliveri wrote: > I know a few guys who installed OpenNMS following this guide without > undue difficulty: > > http://www.howtoforge.com/opennms_network_management > > I don't have any direct experience with OpenNMS myself, but I hear it's > slick. OpenNMS itself is packaged in a few RPMs that will drop into CentOS or the EL version of k12ltsp - perhaps the fedora based ones also. There are just two complications: you need a working tomcat install first - you can get that with yum from the jpackage repository after following their instructions for building the non-free (you have to click the Sun agreement...) java and jta packages. Second, most of the options are set by hand-editing a large set of xml files that aren't very well documented. Fortunately the defaults are pretty useful so you only have to change a few things to get started. -- Les Mikesell les at futuresource.com From robark at gmail.com Mon Oct 30 21:13:29 2006 From: robark at gmail.com (Robert Arkiletian) Date: Mon, 30 Oct 2006 13:13:29 -0800 Subject: [K12OSN] FOSS/K12LTSP in the news Message-ID: Risking shameless self promotion here is the link http://business.newsforge.com/business/06/10/20/2016230.shtml?tid=35&tid=150&tid=132 -- 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/ -------------- next part -------------- An HTML attachment was scrubbed...

I'm sorry but I've reformatted the hard drive for something else at the moment. I will have to buy another H/D and come back to the issue. I thought I had been pretty clear but it looks like there is some 'wiggle room' in what I said. The k12 test server has two cards. One is connected to a 192.168.1.x subnet. As I said, I did a ping yahoo.com and pulled the cable from the k12 server and the ping stopped. This means the k12 server is now isolated from other networks. The other ethernet card goes to a 4-way switch siting on top of the k12 server. A second cable comes from the 4-way switch to a pxe terminal. It gives the message, only after the second boot from the install. I'm redoing the network (luckily, it's small) and moving everything to static and will start over, probably next week when I get another H/D. wash, rinse, do again ;-) -- Regards...Martin From mel at melwade.com Tue Oct 31 03:19:49 2006 From: mel at melwade.com (Mel Wade) Date: Mon, 30 Oct 2006 19:19:49 -0800 Subject: [K12OSN] DisklessWorkstation.com Message-ID: <43080f460610301919g52454911ua1e9c8d3bbe8add7@mail.gmail.com> Anyone know what happened to this site?

FC did install the smp kernel,of course,and this only has 360 MB of ram. It seems like it is going to boot up fast when the services are all loading but by the time it is getting to a desktop,it seem very slow, getting the desktop drawn. When i was trying to get all the software installed that i had copied from one of my previous server,lots,,of rpm's it just kept getting slower and slower. It does show about half of available swap was used, but both cpu's never showed over 5-6 % all the time. By the time I booted one client to this server everything seems very mushy/slow. Do i simply need more ram for this box,or has others experienced the smp kernel being slow? My oldie AMD 1.0 GHZ with 364MB of ram experimental was much snappier than this box.

You can check swap activity by installing the sysstat package and running something like 'vmstat 5' in a window while you do some typical operations. The numbers in the si and so columns show the swap in/out activity. 0 is good. -- Les Mikesell les at futuresource.com From gumprechtm at msad3.org Tue Oct 31 14:07:19 2006 From: gumprechtm at msad3.org (Mark Gumprecht) Date: Tue, 31 Oct 2006 09:07:19 -0500 Subject: [K12OSN] Printing outside the box In-Reply-To: <004101c6fc58$338df220$2305a8c0@acer2e68c49b20> References: <004101c6fc58$338df220$2305a8c0@acer2e68c49b20> Message-ID: <45475897.8020109@msad3.org> I have yet to find a printer that supports postscript that will not work off of the generic postscript printer driver.

No port forwarding. You can do it with vnc client or setup freenx and use the nx client from nomachine.com Freenx is a lot faster.

I changed to KDM by adding DISPLAYMANAGER=KDE to /etc/sysconfig/desktop and then ran gdm-stop which caused gdm to stop and kdm to start. As such, the login screen has changed from the GDM greeter with the picture of the school kids to just a blue Fedora login screen. Logging into KDE and choosing Control Center -> System Administration -> Login Manager, it appears that even with KDM I should see the same thing as with GDM, the school kids picture, but I don't. Nor does changing any of the Appearance settings within the Login Manager seem to change anything. Any explanations for this disconnect and how to fix it?
