From brcisna at eazylivin.net Sun Nov 1 01:32:28 2009 From: brcisna at eazylivin.net (Barry Cisna) Date: Sat, 31 Oct 2009 20:32:28 -0500 Subject: [K12OSN] Thin c850 Neoware low, problem sound and yum Message-ID: <1257039148.25267.16.camel@localhost.localdomain> abegoc, Most of the Neoware TC's have a funky sound chip in that ( I think) they are actually ISA based. I had one of the Neoware's to test with many moons ago,and they did work decent. Get into the Neoware bios at bootup. I think there are two options as to how the onboard sound functions. try one,then try the other. I am not sure, if you are very new to K12LTSP ,if so read up on how to assign each TC a particular ip address via dhcp. This is quite a bit of a learning curve until you have dealt with it for some time. Once you get the TC set to the ip address you will need to add the following entry for that TC(to activate the sound card) in the /opt/ltsp/i386/etc/lts.conf file in dhcpd-k12ltsp.conf add the client as ws010 Add an entry in the lts.conf file like; [ws01] SMODULE_01 = "sb io=0x220 irq=5 dma=1" After you get this all added restart dhcp,and reboot your C50. As the TC boots,shortly before you get to the configuring X,you should see a line "Accepting connections on port 16001". If you do NOT see this line the sound card module did not load correctly. This is a starting point for you. Good Luck! Take Care, Barry Cisna From ssh at tranquility.net Mon Nov 2 00:55:18 2009 From: ssh at tranquility.net (Scott S.)

It is on dialup, and over time has had several additional things installed. The prospect of a fresh install and copying /home over is daunting, due to the things I have installed. I recently took the server to my work's network, thinking I would upgrade everything. The existing repo was no longer in place. After some searching, There was originally a (now) invalid mirrorlist, I decided on the following for my k12ltsp.repo entry in /etc/yum.repos.d baseurl=http://k12linux.mesd.k12.or.us/K12LTSP/5.0.0-EL-32bit/i386 I chose gpgcheck=0 because I figured the gpgkey URLs were invalid as well. Now, yum can find the repo and update the package list. I cannot however do a system upgrade, it fails (I do not have the exact error). I can however manually yum upgrade with this list in place. Questions: 1. What is a valid 'mirrorlist' parameter 2. Can I save this installation without starting over? Everything is working well.

I know that some of you in here have some of our (read: Symbio's) SYM1112 little 4W Geode-based thin client. I first wanted to let those of you who have them know that at least on my test Karmic Koala Ubuntu 9.10 server, they booted up without any modifications or tweaks. Most of the credit for this really goes to Martin-Eric Racine and the rest of the geode driver developers and package maintainers, as well as, of course the Ubuntu devs and the move away from usplash as the bootsplash mechanism. So, a big thank you and a shout out to them! For those of you who are wondering about Symbio, we aren't really in the business of selling thin clients by themselves, and we very much encourage you to buy from vendors such as DisklessWorkstations.com and those who really help support LTSP in all of our endeavors in open source land. At Symbio, we have our own thin clients really as accessories to our other solutions. That said, we have moved away from Geode-based thin clients and have stopped selling the SYM1112. We recently got back 70 or so SYM1112 units on a trade-up deal with one of our customers, and we cannot sell them as new. If anyone would be interested in them, they are great little units and some of the smallest physical and lowest power-consuming ones you'll find on the market. We can sell them at $99 each (excl taxes/shipping) and throw in a free unused VESA mount to mount them to the back of a monitor. Plus, in the spirit of the open source world, we will take 10% of the order and donate it to the school or open source project of your choosing, provided there are appropriate and legal means to make the donation. If anyone on either of these lists is interested, please send me an email offline at gadi at ltsp.org . Note that Symbio does not support thin clients when used with any system other than Symbio's solution, but that's why you guys have me! :) Cheers! -Gadi PS: Obviously, this is a "while supplies last" kind of deal - we hope to find a new home for these thin clients really quickly. :) -- -------------------------------------------------------- Gideon Romm | Proud LTSP Developer ltsp at symbio-technologies.com From mlists at disklessworkstations.com Tue Nov 3 14:30:20 2009 From: mlists at disklessworkstations.com (DisklessWorkstations.com) Date: Tue, 03 Nov 2009 09:30:20 -0500 Subject: [K12OSN] SYM1112 and (Ed)Ubuntu 9.10 In-Reply-To: <1257257634.31739.1.camel@bart.nr.symbio-technologies.com> References: <1257257634.31739.1.camel@bart.nr.symbio-technologies.com> Message-ID: <4AF03E7C.8070207@disklessworkstations.com> Thanks Gadi!

Then I moved to NH. Last year I installed K12LTSP (Centos-based) at a school here. Back in VA, we had also installed Koha on a dedicated machine. At first I tried to get it to run on the K12LTSP server, but it resisted my best efforts. It REALLY wanted to be installed on a Debian machine. I eventually relented and enlisted the help of a Debian enthusiast. He got it up and running on a dedicated machine. Now I'm faced with the prospect of getting Koha up and running again here at the new school. Has anything changed in the last five years? Has anyone gotten Koha to run on K12LTSP? Should I round up another PC, install Debian (or perhaps Ubuntu) and make it a stand-alone box? Please tell me I can just "yum install koha" instead! -- Jim Thomas Principal Applications Engineer Bittware, Inc jthomas at bittware.com http://www.bittware.com (603) 226-0404 x536 Good judgment comes from experience.

If you just need the basic functionality, this is a very stable distribution. K12Linux handles Flash, local applications and newer hardware better, though. Also, keep in mind, Fedora 12 is out in about a week. The reason I mention a new, "unproven" version is because Fedora goes EOL so quickly, officially around 13 months. Fedora 6 hasn't been supported since Dec '07. If you do an installation of F11, you'll probably want to migrate to F12 or F13 (unlucky?) to remain on a supported release.

I'm going on about 4 hours of sleep so at this point of the day I might be getting things out of sequence. I do know that setting PasswordAuthentication to no would keep me from being able to log in on the thin client. I'd get a message about being unable to contact server and the thin client would restart. As soon as I set this to yes that problem when away. Also with the option set to yes I wouldn't be prompted to accept the ssh key for every thin client. Thanks for the information on that option. I'm sure I've mis-configured something somewhere. I'll dig a little deeper tomorrow once I've had a good nights sleep. > >> thin client's sessions so that's progress.

I forgot to > mention, I have only tried Internet access blocking with the standard > 2 nic setup. Not sure if it will work with a 1 nic setup. I'm using a 2 nic setup myself. Everything is working very well. I do seem to have an issue with Find not separating out the computers running a certain process. And the Lock/Unlock button doesn't seem to do anything on the thin clients. Both of those are non-issues for us and not worth troubleshooting...unless that feedback would be useful for you. Also I apparently don't have Snapshots configured correctly (a gThumb error) but once again not an issue. Internet access blocking isn't working for me. The Allow / Deny buttons are grayed out. The features that will be very useful for our implementation (and that are working great) are: 1) Control - if all fl_teachertool offered was this one feature we'd be happy. This is what our support staff will use to remotely support our users. Our environment will be 225 workstations spread out across 40 locations. A majority of our sites have no more than 3-5 computers. I'm going to set up FreeNX on these servers and what our support staff will do is set up a NX session to the server and then launch fl_teachertool. 2) List - another very handy tool. Our support techs aren't all that familiar with the command line. 3) Broadcast - I think this will be very handy for training. Thanks again for the great tool Robert. > > If you get that iptables error again try closing fl_tt and starting it > up again.

You want to use the lts.conf file in /var/lib/tftpboot/ltsp/i386/, IIRC the file in /opt/ltsp is the old location, and isn't used anymore. Try adding X_MODE_0 = 1024x768 to that file. Sometimes this happens because it is detecting the video chipset wrong and using a lower resolution. If you and a shell on one of the client screens you should be able to check what it's using. You can specify X_COLOR_DEPTH = 16 and XSERVER = trident if it still won't give you the right resolution. I think it defaults to 24 bit color on Fedora, which causes a problem for some older video cards, especially at higher resolutions. > > a couple questions: > 1.

I think it defaults to 24 bit color on Fedora, which causes a problem for some older video cards, especially at higher resolutions. OK... Thanks for that info! We edited that file /var/lib/tftboot/ltsp/i386/lts.conf and added the following under [DEFAULT]: XSERVER=trident X_COLOR_DEPTH=16 X_MODE_0=1024x768 and it still would only boot to 800x600. This is what displays as the max resolution under System/Preferences/Display. I still would like an answer to the following questions, to help diagnose the problem. We rebooted everything for this experiment. We also tried: XRANDR_MODE_0="1024x768" >> a couple questions: >> 1. How does one tell if the /opt/ltps/i386/etc/lts.conf file is being read? I have noticed that the command xvinfo does give back that it is running on the trident driver; see bellow. The server gives back a result of NV drivers for the same command, which is correct b/c it has a NVidia. >> 2.

Old pc with a dual core 2ghz intel and 700mb ram - no hdd The issue I'm having is that on the client things seem to be a bit laggy, typing this email into firefox (gmail) for example isn't as smooth as it would normally be, or even be via a remote desktop session to a windows server (just an example). The main bug bear happens when I'm scrolling through a webpage or my inbox list. The other clients on the network are varying in spec, but most are little celeron 700s with 256mb ram. Currently there are two thin clients active, with 2 of us using the web etc. Any help and pointers much appreciated.

Current setup; > There are far more knowledgeable people on this list, but I thought I'd offer a suggestion. Try running "top" on the server while you're using the thin clients. My guess is that you're swapping RAM like crazy. If so, add more RAM to the server. After that I'd look at your network. Is it all 100BaseT at the switch? It is a switch (not a hub) right? A gig uplink port on the 100Mb/s switch to the server can work wonders too. Proper network setup is very crucial for thin client performance. ck From brcisna at eazylivin.net Fri Nov 13 18:28:25 2009 From: brcisna at eazylivin.net (Barry R Cisna) Date: Fri, 13 Nov 2009 12:28:25 -0600 (CST) Subject: [K12OSN] Making thin clients "faster" Message-ID: <46820.216.24.126.66.1258136905.squirrel@www.eazylivin.net> Hamlesh, You did not mention how many concurrent connections you have max at any given time to your server. You should at least bump up your ram in server to 2G as ram is pretty cheap. With just web browsing any TC should be adequate. Only video running will of course kill your bandwidth,especially if you are only using 100MB backbone. A "cheap" upgrade would be to buy you a couple Trendnet 26-port unmanaged switches that have the two GIGE uplinks to get your server to the TC 'room' to feed to the TC's if you are only running 100MB for example. They can be had for about $100 per. Make sure your server does have a GIGE nic on the TC's feeding side(eth0) ,or else the GIGE switch upgrade would be mute. You may considering downloading jperf to measure what kind of throughput you are getting from server to > TC. I made an rpm of jperf which makes it a very simple setup. You simply start jperf in server mode on the server console,go to one of the TC's and run jperf in client mode. It will be a good tool for realtime bandwidth 'watching'. You can download the jperf rpm here,which should work on any current version of k12ltsp, ftp://eazylivin.net/server/jperf/ Take Care, Barry Cisna From hm at motah.co.uk Sun Nov 15 09:25:38 2009 From: hm at motah.co.uk (Hamlesh [Personal]) Date: Sun, 15 Nov 2009 09:25:38 +0000 Subject: [K12OSN] Making thin clients "faster" In-Reply-To: <46820.216.24.126.66.1258136905.squirrel@www.eazylivin.net> References: <46820.216.24.126.66.1258136905.squirrel@www.eazylivin.net> Message-ID: Thanks for the input guys.

In earlier versions of FF, sites that had lots of images would sometimes crash the xserver on the client as a result of using up all the client memory with cached images. This doesn't happen with FF3. It has been rewritten - all images are loaded on the server and transferred across the network without been written into client memory and FF crashing the client xserver is no more. The downside of this is the jitteriness that you are experiencing. On the same (very) graphic-heavy sites where Firefox 2 would sometimes crash (but was otherwise perfectly acceptable in terms of performance) Firefox 3 scrolls slowly and is quite jittery redrawing the screen with significant errors, overruns, and dropped packets on the network. I had hoped that the faster page rendering in Firefox 3.5 would help but the change is not enough to make up for the performance drop on the clients. I still use FF but use Opera for anything other than sites that are mainly text. I'm on a 100Mb network with GigE to the switch. If you can get GigE network cards and a GigE switch you should see a big improvement in performance.

That's why people were suggesting that 1GB of RAM was perhaps not enough memory for even just your three clients. As for Skype, since the app is running on the server, just to test it, try plugging the mic into the server and it will probably work, although that's not likely what you want. With that all said, LTSP 5 (K12LTSP uses LTSP 4.2, K12Linux uses LTSP 5) took a more standardized approach to sound on the clients, although not all apps work well with it. LTSP 5 also has support for running apps on the client rather than the server (local apps). A few other people have wanted to do what you what you're trying, and, if memory serves, they opted for running apps like Skype on the clients. Search the LTSP mailing list archives for skype for details.

In earlier versions of FF, sites that had lots of images would sometimes crash the xserver on the client as a result of using up all the client memory with cached images. This doesn't happen with FF3. It has been rewritten - all images are loaded on the server and transferred across the network without been written into client memory and FF crashing the client xserver is no more. > > The downside of this is the jitteriness that you are experiencing.

One way to do this is to set: SCREEN_02=shell SCREEN_07=ldm in lts.conf and reboot the client. Once the client is booted, you should be able to press ctrl-alt-F2 to get to screen 2 and be presented with a root shell on the client. If you do not get a root shell, your config file is not being read. 2. Look in the client's Xorg log file. If you follow #1 above, and it *does* work, from the root shell, scp the Xorg log file to the server: scp /var/log/Xorg*log user at server:/home/user Then, attach the log file to an email to this listserv, if you want some help with it. The log file will give you all the gory details of what modes it rejected and why. That should give you all the info you need to adjust things properly and not to guess. :) -Gadi PS: One other note: in some older versions of LTSP5, you needed to add a line: CONFIGURE_X=True in order for a xorg.conf file to be created from your parameters. Try adding that line to your pasted configuration and see if that helps.

Also, for Disklessworkstations Term 1220 systems, you need the following options for those clients: X_OPTION_01 = "\"HWCursor\" \"off\"" X_OPTION_02 = "\"SWCursor\" \"on\"" And that will fix the ghost cursor issue (in particular with the use of rdesktop).

I'm sorry I didn't mention that. I had thought about trying to install libgcrypt from rpm, but couldn't figure out a way to be sure I was acquiring the right rpm. Based on the other suggestion I now tried yumdownloader, but didnt' get a better error message, IMO.

This "libgcrypt11-1.4.0-15.el5.i386" package definitely is in the ATrpms repository. The libgcrypt-1.4.4 package provides a newer version of the GNUTLS library, which is libgcrypto.so.11. It's that file that's giving you fits here. I ran into a similar issue with another package, so what I did was rename the MyConflictingFile.Whatever (in your case, /usr/lib/libgcrypt.so.11) to MyConflictingFile.Whatever.bak. Now, on my system, "libgcrypt.so.11" is actually a symlink to the real file, /usr/lib/libgcrypt.so.11.5.2. Therefore, I'd just rename both of them to have the extension ".bak" or something similar. Then, try your yum update again and see what happens. If that doesn't work, then I'd try installing the libgcrypt-1.4.4-5.el5.i386.rpm package with rpm's "--force" command. Since it's just a newer version of the GNUTLS library, that shouldn't break anything (I know, Famous Last Words). --TP From dhhoward at comcast.net Sun Nov 22 18:37:06 2009 From: dhhoward at comcast.net (Daniel Howard) Date: Sun, 22 Nov 2009 13:37:06 -0500 Subject: [K12OSN] unusual shared folder for teachers In-Reply-To: References: Message-ID: <4B0984D2.9030701@comcast.net> I just set up a 1:1 classroom for an language arts teacher so students can spend much more time doing their essays, etc. on the PC in class, start digital portfolios, etc., and one request from the teacher that came up is to have a shared folder for students to drop copies (and serve as backup) of their documents, but have it so that students can drop folders there but cannot read other's work, and in particular not delete other's work, so permissions have to be set in a new way (for me at least). Then, after the teacher edits their work, he wants to put it back on their desktops. The teacher has a classroom server running K12LTSP 5EL (I just couldn't get the old laptops working right in K12Linux, sadly), and he has about 100 student accounts for his 5 classes. Any advice? Also, I'm going to train him on how to use fl_teachertool, but won't get to until after Thanksgiving due to our schedules. Is there a simple command he can issue in the meantime from the command line on his server to log all users off at the end of one class so that students don't sit down and start doing things on another student's account (like cyber bullying)? After a while, students will log in to get their customized desktops, but for now I want him to have a way to force things. Any other suggestions for a 1:1 language arts class that would really show the power of a classroom server-based thin client system?

What you do is set permissions on that directory (folder) to 730. Ownership would be by the language arts teacher, and the group ownership would be by "students". Your students's userID's would all be in this "students" group. What we're doing here is giving full permissions to "lateacher", but write-only and permissions to group "students". The kids can upload all they want. They can even re-upload over what they just uploaded to you, since the file will be owned by their own userID's (say if they make a last-minute correction and want up upload a newer version). But they cannot see anything that's in that directory, not even the file they just uploaded. Furthermore, they cannot clobber any file owned by any other userID; e. g. "student1" cannot mess with a file owned by "student2". So, when you're done, it'd look something like this with an "ls -l". drwx-wx--- 2 lateacher students 4096 Nov 22 14:13 LA-SharedFolder/ I did this with a test directory of /LA-SharedFolder.

As for logging all students off, I wrote this for some teachers a few years ago: # logoff all the users except the teacher me=$(whoami) for x in $(last |grep still |cut -f1 -d" " |uniq) do if [ "$x" = "$me" ]; then continue else pkill -u $x fi done This was part of a larger script, called by an icon on the teacher's desktop, that logged out all students and then shutdown the client machines (but without knocking off the teacher who was also on a thin client). So, you could email the above as a file to the teacher along with steps for making it executable, how to call it with sudo, making sure the teacher is in an appropriate sudoers group, etc (perhaps you could do it yourself if you have ssh access to the server, which I'm guessing you don't). With all that said, I think it would be easiest to just tell the teacher to try fl_teachertool. It's pretty self-explanatory.

What do people recommend as a good min of ram and then what would be a good working level to have (I'm thinking 512MB -> 1 GB).
