From lewis at pcc.com Wed Oct 1 15:15:45 2008 From: lewis at pcc.com (Lewis Holcroft) Date: Wed, 1 Oct 2008 11:15:45 -0400 Subject: [K12OSN] mrepo Message-ID: <3400D20F-9F11-40BE-85E8-8F24F0297C0D@pcc.com> Hi all, I have a machine in my office and it has mrepo set up to keep a local mirror of CentOS-4, CentOS-5 and K12LTSP/5.0.0-EL-64bit. The problem is that K12LTSP is not getting updated. the config file contains the following: [K12LTSP-5EL-x86_64] name = K12LTSP $release ($arch) release = 5EL arch = x86_64 metadata = repomd repoview yum ### ISO images iso =k12ltsp-$release-$arch-?of?.iso #os = http://k12linux.mesd.k12.or.us/pub/K12LTSP/5.0.0-EL-64bit/5.2 ### Additional repositories updates = ftp://k12linux.mesd.k12.or.us/pub/K12LTSP/5.0.0-EL-64bit/updates I've checked the wiki and mail archive and have found the following link http://k12ltsp.org/mediawiki/index.php/DownLoad If I select the "Version 5-EL, 64-bit, CD" link my browser tries to connect to ftp://k12linux.mesd.k12.or.us/pub/K12LTSP/5.0.0-EL-64bit/ iso, but never connects. I should also mention I inherited this machine and its configuration. I know I would prefer to use rsync over ftp. Does anyone else use mrepo and if so be prepared to shed some light on optimal config file setup. Thanks in advance.

I think it was a combination of not having the "URI" configured for my subnet (it was ldap://127.0.0.1/ in all the LDAP conf files) and not having the proper holes punched in my firewall on the server. I think I'm still having a firewall issue though. I'm getting an error that says that the "Gnome setting daemon" is timing out and that some settings might not work (after a very loooong login time). When it finally logs in I'm indeed getting my /home folder from the server and authenticating the user off the server. But the login performance and error message are unacceptable. I'm so close. Can someone please: A) tell me what ports need to be open (UDP or TCP) for this whole LDAP authentication and NFS home directory exporting business to work? and B) could something else besides the firewall being misconfigured be causing this problem? I've got ports 389, 2049, 139 and 445 open for TCP and 137 and 138 open for UDP. These are just open for the subnet that the clients are logging in from. There's a few other open ports, but I'm pretty sure they're irrelevant. (80, 22, 25). Thanks so much for all the help so far (and hopefully a little bit more to get me established with the smbldap configuring). ck From rob.owens at biochemfluidics.com Thu Oct 2 14:37:04 2008 From: rob.owens at biochemfluidics.com (Rob Owens) Date: Thu, 02 Oct 2008 10:37:04 -0400 Subject: [K12OSN] OT - Almost there with smbldap authentication In-Reply-To: <48E4C794.3060800@snarlnet.com> References: <48E4C794.3060800@snarlnet.com> Message-ID: <48E4DC90.1090500@biochemfluidics.com> I can't answer your question, but I suggest that you either 1) test this with your firewall turned off, or 2) check your firewall logs to see if you can identify any traffic being blocked. -Rob Carl Keil wrote: > Hey Folks, > > I solved my previous problem (not able to query the LDAP server from the > client).

I'm not sure if they are there anymore in 5, I haven't had to adjust mine yet! In LTSP 5 we might just be using the settings in the GNOME/KDE display managers. If I were you, I'd disable standby and suspend, IMHO, just sent the off time to something reasonable like 15 mins. I've always found DPMS off to be the most reliably implemented in all different hardware, though power management is less of a problem with hardware than it used to be.

So that shoots that down . Wireless can work if you have a client with a boot kernel embedded on a flash drive or similar with the drivers installed for the wireless NIC. But then running X sessions over a wireless connection will be problematic as each client uses 7Mbps MINIMUM. An 802.11g system that provides 54Mbps will only support 5 clients using basic desktop and NO multimedia. It's just too slow. This won't change any time soon. However, for the "gotta be mobile" enthusiasts, an option to look into is a tiny X environment on a mobile device and freenx on the server. That will reduce the X bandwidth hog to a trickle and support bi-directional sound as well. Will it work streaming media and flash heavy sites all over a wireless network? I haven't done the engineering on that to say if it's possible/feasible/nuts.

I believe there was a thread on doing wireless clients a while ago. Conclusion: forget it, because access points function as hubs (not switches) and the bandwidth needed for LTSP is going to kill your wireless network. LTSP doesn't need a lot of processing power on the clients (hence the 'thin'), but it does need quite a bit of bandwidth (hence the gigabit interfaces on the server). I guess only fat clients is feasible over wireless. But I haven't done any testing myself, so YMMV. Nils Breunese.

Just rpm in the Openfire package and start connecting to it. It WILL work with thin clients,been there done that:) --Thanks Barry I will give it a try.

In-Reply-To: References: Message-ID: Here are the instructions (verbatim) that Terrell posted on my request of how to downgrade from FF3. except for step 10 where the link name is missing. I added what I used. I'm guessing that they should just work going the other way as well? The other thing I have also found useful is using gconf-editor to make sure that the panel launchers launch mozilla-firefox.desktop as opposed to the default setting. Sincerely, Dave Hopkins ---------------------------------------------------------------------------------------------------- RPM repositories aren't always the answer. You could do it the same way I do it on some of my systems (CentOS, Slackware, etc.). Just download the Firefox 2 tarball (not the "installer" package, I mean the other one, it's about 9.3MB), un-tar it into, say, the "/usr/local/firefox2" directory, and symlink /usr/bin/firefox to /usr/local/firefox2/firefox. Boom, you should be good to go. Here's how I do it, step by step: 1.) Download Firefox 2.x to some directory (we'll say /home/temporary for this example). 2.) Become root. 3.) cd /usr/local 4.) tar -xvzf /home/temporary/firefox-2.0.0.x.tar.gz 5.) ls -l (you should see a "firefox" directory now) 6.) mv firefox firefox2.0.0.x (this is just for you to remember which version of FF it is) 7.) ln -s /usr/local/firefox2.0.0.x /usr/local/firefox (just a symlink to make it slightly easier to upgrade later, not required) 8.) cd /usr/bin 9.) mv firefox firefox.bak 10.) ln -s /usr/local/firefox/firefox firefox And then, give 'er a spin. You should be able to click on any of the "Firefox Web Browser" icons and have v2.0.0.x come up. --TP ---------------------------------------------------------------------------------------------------------------------------------------- On Fri, Oct 3, 2008 at 1:33 PM, Joseph Bishay wrote: > Hello, > > I hope everyone is doing well. > > I am running ltsp on fedora core 6 (k12LTSP) but the browse is > version 1something.

All the directories seem to be installed now as well. The default install of squidGuard on K12LTSP EL5 is not working correctly and requires significant work to get it as far as I have, especially with the squidguard.conf file and the blacklist directories and files, which would lock up due to no content in several of the directories listed in the default squidguard.conf file. However, my setup still has one more issue, which seems to be in the verification that squidGuard is actually working. Also, I would still like to get someone's input on their working configuration. I would like to see their squidguard.conf file and how they setup a thin client browser to use the proxy. Any help here is greatly appreciated.

Again, it's a very bad idea, given how wireless networking works. If you want to try it...then good luck! The fact that it's "N" wireless doesn't change things.

Terrell is right. The only way I found wireless useful in LTSP environment was to bridge networks in two buildings where I couldn't run fibre or wire. Plain vanilla G is fine for 3 terminals and 6 thick clients, as long as no heavy on graphics apps are run - disable screen savers! julius From jkinney at localnetsolutions.com Sat Oct 4 17:17:30 2008 From: jkinney at localnetsolutions.com (James P.

It is EXPENSIVE!!! Wires may cost $$ to run but once in they rarely fail. Wireless requires SKILLS to maintain and $$$$$ to install. Most schools systems are hurting for solid tech support and adding wireless on top is just salt in a wound. Wireless is good for board rooms (execs do very little important work anyway) and college campus and home. Laptops are a BAD idea for schools most $$ for least compute power. Easily broken. Expensive to fix. Wireless devices use batteries that MUST BE REPLACED $$$$$ Don't bother. Don't use it. Stay away from wireless. It is not, and will never be suitable for K12 schools as long as they are as poorly funded as now. To achieve the thin client access level with wireless (using an onboard boot ROM and not PXE) it will cost 3X the cost of wire PER CLASSROOM. You _STILL_ have to run a wire to each AP. So a 16 port Gbit switch cost LESS than a solid AP that can support 14 clients and a printer.

Actually, I find NFS somewhat easier. Anyway, here's how. There are three parties in this process. They are the following: A.) the box you're using to download the CentOS 5 DVD image (probably your "daily driver" workstation--mine's a Kubuntu box), B.) the box that you're going to use as an "installation file server" when you do your installs (mine's a Slackware box, but this can also be the same as the box in A.), and C.) the box on which you're going to perform the actual FTP installation once all this is set up--that is, your K12LTSP 5EL server-to-be. With the introductions out of the way, let's get to it. 1.) Download the DVD ISO image. It's nearly 4GB. 2.) Mount that DVD ISO image as a so-called "loop" mount. That's done as follows, using "/mnt/dvdiso" as my mount point. mount -t iso9660 -o loop NameOfDVDISOImage.iso /mnt/dvdiso 3.) Find some box with enough space for the contents of the DVD and copy the entire contents of the DVD (everything under /mnt/dvdiso, in this example) to that box. Any such box will do; I'm assuming here that it runs some GNU/Linux distro. On my "installation file server", I use the directory /var/nfsshare, because I started out doing NFS installs originally. You can use whatever dir. you want. Ensure that permissions for this entire subdirectory tree are set to world-readable, for obvious reasons. :-) You do that like this. chmod -R 755 /var/nfsshare 4.) Install vsftpd. On RH/CentOS/Fedora, this is done by "yum install vsftpd". 5.) On this "installation file server", set up your FTP daemon to point to that directory. With vsftpd, the config file is /etc/vsftpd/vsftpd.conf. Ensure that anonymous access is turned on in that config file (it's well commented). By default, it is turned on. 6.) In /etc/passwd, change the home directory for user "ftp" to point to your CentOS installation directory. In this example, that's /var/nfsshare. 7.) /sbin/service vsftpd start 8.) Time for a basic functionality test. From another box, try FTP'ing into that "installation file server" and downloading any file. That should work. 9.) Now that you've made sure basic functionality works, here's what you do when you want to do an FTP install. For "server name", put in the IP address of this "installation file server." For your directory, just put in "/". That oughta do it. Since I regularly do CentOS installations at work, I have hugely benefited from setting up an installation file server. NFS installs are equally easy, BTW. All you have to do is install the NFS server and set up your /etc/exports file to look like this. # My /etc/exports file # /var/nfsshare *(ro,async,all_squash) Then, "/sbin/service nfs restart" for that new exports file to take effect. And so, during your network installs, you'd use the same IP address, and the directory you'd put in would be "/var/nfsshare". And thus shall coolness envelope you...for you will have become more 1337.... --TP _______________________________ Do you GNU ?

I agree with Jim that when doing an enterprise server model, where the wireless links to classrooms would be between servers and clients, wireless is a very bad idea, and likely to stay a bad idea until we get speeds in excess of 400 Mbps, since real speed over wireless is usually about half of the stated PHY layer speed, so 54 Mbps is really about half the Mbps in reality. But wireless links to a classroom server are still viable and cheaper if they were only more user friendly in Linux (a point to Jim's $$$ labor cost), since $70 for an access point and $30 for a wireless NIC is still less than half the cost to wire a classroom (usually at least $200), and subsequent rooms nearby would be only $30. But getting wireless to work in Linux is not always easy, which is I think Jim's point, due to things like chipsets changing rapidly and not being supported in Linux, although I suspect it will get easier over time as well. And for rooms with older wiring, or wiring that runs by noisy electronics, that the school won't have the budget to rewire anytime soon, wireless is useful as a backup and alternative. And wireless to classroom K12LTSP servers doesn't require batteries, of course. If we could generate a decent list of supported wireless NICs for classroom Linux servers (and keep it up to date) I think wireless would have a strong place for K12LTSP deployments using the classroom server model. Plus, if I were in a school that had a really hostile IT department that said no way to K12LTSP on their network, one of the ways to set it up w/o them and their network being affected would be a classroom server with a 3G broadband wireless access card. I've seen folks with Linux laptops with 3G access, so I know it's at least possible. Not the best long term solution, agreed, but a way to get a foot in the door perhaps. And if I ever had the time/resources to really evangelize this, a Laptop server with 3G Internet (as backup to a wireline) connected to a switch and thence to a handful of netbooks/UMPCs would be a great roadshow kit to cart around to show schools. The point about laptops is important: what makes wireless really critical is when laptops become cost effective for schools (note when, not if). Already we now have companies breaking the $100 barrier for UMPCs, vis a vis, the HiVision Mini Note: http://techvideoblog.com/ifa/98-linux-laptop-the-hivision-mininote/ At less than $100, it is a viable solution for elementary and perhaps even middle schools, and given the lack of moving parts, should be much more reliable, albeit not as fully reliable as a desktop, but approaching it. Better reliability can be had if it's not a 1:1 program, rather a 3:1 or 2:1 with them if they stay in the classrooms and thus don't get banged around between school and home. My company has wireless deployed throughout all corporate locations so that anytime I attend a meeting, whether I'm in someone's office or small conference room, or board room, I merely boot up my laptop, log on, and I'm connected. Most of my customer locations are likewise, but sometimes they lack an unsecured network for guests, although that too is changing. It is not merely a boardroom thing anymore, and I'm sure this model will spill over into schools when the cost of the laptop (acquisition and support) gets low enough to make them viable, which I'm convinced will happen eventually, and I'm guessing in only a few years now.

A $70 AP is quite limited in power and connectivity. It still requires a copper connection. And each client machine requires a $30 NIC instead of a $10 NIC. A 54Mbps AP provides 37.8Mbps of usable client bandwidth. Jumbo frames are not an option in the wireless specs. Since a current thin client requires a minimum of 7Mbps with no sound or streaming video that puts the maximum client count per AP at 5. With a measured benefit ratio of 3:1 students:clients that puts the max class size at 15. In Georgia the max size is 24. So that puts the thin client using wireless into the 4.8:1 ratio which has been shown to be ineffective. So a WAP ($70) plus 5 clients ($30 *5 = 150) requires $220 and is not expandable and won't provide enough classroom exposure to make a statistically significant academic benefit. Most systems ship with an onboard NIC. An 8 port Gig switch is $70 (A 10/100 is $30). A managed 8 port is $110 - retail. So a wire is already run for the (theoretical) WAP, plug in the switch (save $210 per classroom - $30 * 7 clients) and get the 3.4:1 back. And at only 49Mbps, there is expansion room to support streaming video (limited) over a 100Mbps wire for 7 clients or add more clients using a Gbit feed from the upstream switch. Yes. Wireless is "sexy". It's mobile. But the reports are in from all over corporate and college campuses - it's EXPENSIVE to set up and maintain well. My money is on the wire.

Message-ID: <1223422264.25192.13.camel@localhost.localdomain> Randy, There are a lot of variables here with the information you have given. Are your users home folders on the SAME server? If the users home folders are on a separate "fileserver"( not this server),,then it is understandable why you are getting the access denied" if NFS is not starting up for you.IF, the home folders are on THIS server and you can not even browse the folder from the server console.I would get rough, and do from a terminal: chmod -c -R 755 /home This is not exactly cosher of course but at least you should be able to get the users seeing their home folders. This (should) get it going for you.Also what happened when you try and open a terminal from the console of the server. Does the terminal window hang for a while ,then open or may not open. If this is the case I would guess for some reason your hosts entry for this server has went south on you. Open the /etc/hosts file and make sure you have an entry: 127.0.0.1 FQDN localhost.localdomain localhost Not sure why your nfs will not start. Copy/Paste your exports.conf file. Maybe you fatfingered/typoed something in it,to cause nfs to bomb out on startup. Just a few things to try here,, Let us know your findings.

In-Reply-To: References: Message-ID: <1223427153.25301.33.camel@merlin.localnetsolutions.com> First thing is to get the NFS service back up and running. Without it, if you are using NFS mounted /home, nothing will work right. nfsstat will show data about the nfs server and client connections. Open 2 console screens (-F1 and -F2) not X screens on the NFS server. On screen 1 run tail -f /var/log/messages and on 2 run service nfs stop; service nfs start Now look at screen 1 for what is the problem. If stumped, grab the last 30-40 lines of /var/log/messages after this and post them here. It may be that network settings are suddenly wrong and there is no NIC on the same IP address as the nfs server (plugged wrong cable into upstream dhcp server - it happens :-) Last resort: shutdown -r now on the nfs server. Let it fully reboot and watch the stat up screen for errors. Then restart the other servers. BTW: It's a good idea to do "destructive testing" and verify that a simple reboot will restore functionality to a fouled up server. Have it running and literally pull the plug. If it doesn't reboot without "futzing" fix the reboot process so it does. fsck is the only outstanding issue that can't (easily) be worked around.

To use nx one must have a fully working mobile system. It can't PXE boot over wireless. It must have all it's bits stored locally. It must have the ability to authenticate the local user before they are presented the nx client login. Wireless will run remote applications using nx quite well.

I believe this is referred to as transparent proxy. I know my squid/squidGuard configurations are working now since I can configure a thin client browser to use the proxy server (K12LTSP EL5) and it works just fine. I've set up transparent proxy in the /etc/squid/squid.conf for squid v2.6 but it does not work. Setting is: http_port 127.0.0.0:3128 transparent I think the reason transparent proxy is not working is because I do not have any iptables redirection of browser http traffic to the proxy server (K12LTSP EL5). Please advise. -----Original Message----- From: Moon [mailto:moon at smbis.com] Sent: Saturday, October 04, 2008 03:01 AM To: 'Support list for open source software in schools.'; 'Lewis Holcroft' Subject: RE: [K12OSN] squidGuard not working OK, I seem to have muddled my way through getting squidGuard and the blacklists installed. All the directories seem to be installed now as well. The default install of squidGuard on K12LTSP EL5 is not working correctly and requires significant work to get it as far as I have, especially with the squidguard.conf file and the blacklist directories and files, which would lock up due to no content in several of the directories listed in the default squidguard.conf file. However, my setup still has one more issue, which seems to be in the verification that squidGuard is actually working. Also, I would still like to get someone's input on their working configuration. I would like to see their squidguard.conf file and how they setup a thin client browser to use the proxy. Any help here is greatly appreciated.

So given that I would suspect there are a number of items that are not completely ready to run with squidGuard on K12LTSP. I looked at the squidGuard site and read their docs and thought about installing from scratch since it looks pretty straight forward, but the problem with that would be that I might not get updates.

So, if you don't have parents like me to run wires through ceiling, then the cost tradeoff is either $200-250 to rewire a room, or $100 ($70 plus $30 NIC in classroom server), and given you can put $30 wireless NICs in nearby classroom servers, I still contend that wireless is worth keeping in mind for LAN to classroom server connections when needed, and thus would hope that K12LTSP keeps some kind of wireless NIC support for those cases, and better, some documentation on which wireless NICs to use for K12LTSP when that option is needed. I had a need for that two weekends ago when a room I was giving a seminar in on how to use K12LTSP to revise old PCs at my church only had wireless to the room. I ended up running a wire through the ceiling from a nearby room and gave the talk with clogs of ceiling tile all over me...

Recently, I installed the newer 0.62 version of fl_teachertool as our computer skills teacher wanted to use the broadcast feature. The manual installation process seemed to go okay (made me really appreciate being able to just yum install something). All functions seem to work okay except for broadcast. When the teacher clicks the Broadcast button and the VNC window appears, instead of seeing the normal login prompt, the window just stays completely black. When I checked the system messages log, it said that gdmgreeter was having a segfault right after the vnc viewer started, and right after the segfault the vnc viewer shut down. Also, when I try "teachertool-vncviewer localhost:1" the VNC window appears, then quickly disappears. Usually with a message saying something like "connection reset by peer". Anyone have any ideas on what I can try in order to get the fl_teachertool broadcast feature working?

I adapted the script killer.sh as follows and it seems to work well. I replaced the "who -u" with "ps aux" because it seems sometimes some users aren't in the who -u list. I run it at night to keep things clean. Comments would be welcome. Also, if anyone has a script to kill idle user sessions that would be great -- that's next on my to do list. ### This defines USERS using the ps command USERS=`ps aux | cut -f1 -d ' ' | sort -u` ### I don't want local machine accounts to be killed, ### just my Active Directory domain ones. The funny USER ### addition is to remove the first line of the ps command NO_TOUCH_USERS=`cat /etc/passwd | cut -f1 -d ':'`\ USER for user in $USERS; do echo $user GO=1 for no_user in $NO_TOUCH_USERS; do if [ $no_user = $user ]; then # echo NOT killing $user GO=0 fi done if [ $GO = 1 ]; then # echo killing $user skill -KILL -u $user sleep 1 skill -KILL -u $user fi done From robark at gmail.com Thu Oct 9 21:35:12 2008 From: robark at gmail.com (Robert Arkiletian) Date: Thu, 9 Oct 2008 14:35:12 -0700 Subject: [K12OSN] fl_teachertool 0.62 problem In-Reply-To: References: Message-ID: 2008/10/9 David Whitmer : > We've been running K12LTSP v7 for a while on some of our computers. > > Recently, I installed the newer 0.62 version of fl_teachertool as our > computer skills teacher wanted to use the broadcast feature. > > The manual installation process seemed to go okay (made me really appreciate > being able to just yum install something).

It doesn't sound like an fl_teachertool problem. It sounds like a configuration problem with vnc. Usually people have problems following the instructions here http://www3.telus.net/public/robark/Fl_TeacherTool/installation.html but I don't think that's your problem. I have not tested on Fedora 7. > > Also, when I try "teachertool-vncviewer localhost:1" the VNC window appears, > then quickly disappears. Usually with a message saying something like > "connection reset by peer". This is not supposed to happen. It sounds like the mechanism to start Xvnc and provide a gdm login by xinetd is borked somehow. I can't remember how Eric set that up. It's always just worked like magic in k12ltsp for me. Here is an idea, try this. Instead of teachertool-vncviewer localhost:1 try vncviewer localhost:1 If that works then try recompiling tightvnc; if it doesn't then it's your systems vnc setup that's messed up. -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada Fl_TeacherTool http://www3.telus.net/public/robark/Fl_TeacherTool/ C++ GUI tutorial http://www3.telus.net/public/robark/ From dvanassche at gmail.com Thu Oct 9 22:25:36 2008 From: dvanassche at gmail.com (David Van Assche) Date: Fri, 10 Oct 2008 00:25:36 +0200 Subject: [K12OSN] Fwd: Documentation, Wiki, IRC updates In-Reply-To: <48EE55EC.5040500@logicalnetworking.net> References: <48EE55EC.5040500@logicalnetworking.net> Message-ID: <8cc423ef0810091525t493376acga2cd4189e81f3d24@mail.gmail.com> This was sent to edubuntu and ltsp, but is also relevant to the k12ltsp list...

Can you vnc to the server itself( without FL_TT)? In other words from the server console open up vnc then use 127.0.0.1 to connect to the localhost? If this fails I would bet you need to add an entry in your /etc/hosts file of: 127.0.0.1 FQDN localhost.localdomain localhost I found that starting with K12LTSP-EL5 you end up with only an entry for the server with an IPV6 entry in the /etc/hosts file? Something to try...Could be a miriad of things.

Message-ID: How difficult would it be to set up multiple servers on the same LTSP network using K12LTSP? I want students to be able to do 3D editing with Blender and would like to be able to share the processing load over two servers. I also would like one server to handle the entire lab in case the other crashes. Ideally, the takeover would be automatic. If the server not containing /home goes down, I imagine half the clients might find themselves logged out, but would be able to log in again. If the server containing /home goes down, the situation would be more complicated. In that case, everyone would probably be logged out and a temporary /home mounted until the crashed server could be brought up again. BTW, as it stands now, I have only one server. However, I do have two disk drives on the server. I put /home and /var on one drive and everything else on the other drive. (I put /var with /home because all the users have a public_html symlink that goes to /var/www/html/students/username.

If space is not a problem I would rather do a RAID1 mirroring with two disks so that even if a disk crashes (more likely than a server) data remains available and services do not stop. -- Regards, Sudev Barar Read http://blog.sudev.in for topics ranging from here to there.

I cant imagine that there is.. 2. do an: service vncserver restart -- two times.. then look in the system log and see what error was thrown. 3. if vncserver still does not start.post your /etc/sysconfig/vncservers and vncts.

XFCE might also put the menus in simple config files. Gnome uses GConf. You can all sorts of things like locking settings for all users or changing defaults using GConf, but it's a bit less intuitive then some plain text files at times. We used it to change the default mail client to Thunderbird for all our users for instance. You should be able to use Sabayon to create default desktops set to your liking, but I have never been able to get that to work myself (and didn't have a real need, so I didn't spend too much time on it).

To make this work on K12LTSP-EL5, you can use the gdm from Fedora 6 this way: Download the source rpm file for gdm from Fedora 6; you can find it at http://archives.fedoraproject.org/pub/archive/fedora/linux/core/updates/6/SRPMS/gdm-2.16.5-2.fc6.src.rpm Then, as root, run 'rpmbuild --rebuild gdm-2.6.16.5-2.fc6.src.rpm'. (Depending on what you have installed on your system, you may get some errors about missing dependencies; just use yum to install them all. And rpmbuild comes from the rpm-build package, which you can also install with yum.) When rpmbuild finishes, you'll have an rpm for a new gdm: /usr/src/redhat/RPMS/i386/gdm-2.16.5-2.i386.rpm Install this with rpm -Uvh /usr/src/redhat/RPMS/i386/gdm-2.16.5-2.i386.rpm And then you'll need to restart gdm which will kick anyone logged in via GUI, including you. But then the timed auto-login should work. I'll add this to that wiki page.

But it appears I already updated the wiki page for K12LTSP-EL5, complete with links to an already rebuilt gdm package that you can just drop in on your K12LTSP-EL5 system. I have this running on a couple of my systems, and yum does not list any newer versions of gdm. So, if the steps in the wiki page didn't work for you, I'm a bit confused and will need more info about the state of your system and what errors you're getting.

There is Ubuntu (I know it is different, but ... ) bug report about the error message I am getting concerning esd and the inability to preload libesd*.so.0 It appears to be an issue with preload trying to load 32 bit drivers since if I modify the script to point at the 64 bit libraries, the errors go away, but I don't get any sound in either event. I found the src rpm (http://download.fedora.redhat.com/pub/epel/5/SRPMS/repoview/pulseaudio.html) for pulseaudio, and will try and locate all the other src rpm's that pulse requires as well as listed on their website.

I use gconf-editor which allows setting default and mandatory settings for the gnome environment. Have to be careful on the mandatory settings though since it applies to everyone and that can cause problems even for the root account as I found out the hard way.

There is a little more about this in the documentation along with links to relevant sites. This gives you a visual Xnest environment in which you can adapt your thin desktops as you want and then put different users in groups so they get one experience or another. You can lock down the client this way or set up exam accounts with just a couple of menu options, or add common files and programs to the desktops for groups of users. I have used it successfully, though Sabayon is qutie buggy and is prone to crash. If you can work around crashes though, it will do the job.

It would be worth a shot. Those commands will not do anything (package names don't end in .rpm usually, you're using filenames, but that won't work with rpm -e) and I'm not also sure why exactly you are suggesting this.

We have also setup print and USB access for them to save there data to a thumb drive or print it out. We presently aren't saving data on the server, but our next upgrade of the system will allow for individual login accounts. To setup up autologin you can make changes to your gdm config file (in our instance, /etc/gdm/custom.conf), to set it up to log in automatically. We have given the thin client name the same name as the hostname which is all determined by DHCP, so the studfents don't even have to know the hostname they are logged in as, nor do they know the server that they are logged into (we have anywhere from 2-5 application servers at each school).

The easiest way to root any Unix-like machine is to start it in single user mode (add '1' or 'single' to the kernel boot parameters). That way you are logged in as root without being prompted for a password. Once logged in you can run 'passwd' and set a new root password. No boot disc needed. :o) (If your boot loader is also password protected or if runlevel 1 is protected and you don't have the password things get more difficult.) Nils Breunese.

Highlight the entry you want to boot, hit 'e', move to the kernel line, hit 'e'. Add ' single' to the end of the line, then hit 'b' to boot. You'll get a root shell prompt where you can run the passwd command. Type 'exit' to quit and reboot. 2nd choice - good for more complicated damage: Boot the install CD with 'linux rescue' at the boot prompt. Let it mount the installed system. Type the chroot command that it will suggest. Do whatever maintenance you need to fix the system. Type 'exit' twice when done (once to exit the chroot shell, once for the top level). -- Les Mikesell lesmikesell at gmail.com From ahodson at elp.rr.com Sun Oct 12 22:41:53 2008 From: ahodson at elp.rr.com (Alan Hodson) Date: Sun, 12 Oct 2008 16:41:53 -0600 Subject: [K12OSN] Wish my Centos5 server was a Mac In-Reply-To: <48F278B7.1070600@gmail.com> References: <48F26AC6.8070809@elp.rr.com> <48F278B7.1070600@gmail.com> Message-ID: <48F27D31.3000903@elp.rr.com> Thanks Les, Tim and Nils.

Now I have the problem that, if a file has been synced, you cannot delete it. It reappears at the next sync. What I want to happen is to go through each user in /home and see which version is most recent (the one on server1 or the one on server2). Then I want to only rsync from most recent to older, with the "--delete" option to remove files that were deleted recently. I can imagine having a script (running on server2) that does a local "ls -l /home" and a "ssh server2.ltsp ls -l /home" and compares the modification times and then does the rsync in the appropriate direction for each user's directory. Can anyone think of a more elegant solution?

Only to add some experience I had with several servers setups. The best is the have a NIC (3com/Intel/Realtec) in the server that is supported out of the box from the installation. downloading and compiling drivers is supported but in the long just a hassle. Especially when you have no Internet connection to download the driver. I had this situation in a orphanage in West Timor. On the client side I am really amazed about the *BootDisk522 *and the support whatever NICs, at least whatever unkown model of NIC I use works with this boot floppy disk. A cheap PCI NIC with PXE inbuild would be a better solution for our projects with donated hardware. -------------- next part -------------- An HTML attachment was scrubbed...

Here's the relevant code, which could be easily adapted to a server environment: cat < /etc/cron.hourly/copyusers # !/bin/sh set -e awk -v LIMIT=$UGIDLIMIT -F: '(\$3>=LIMIT) && (\$3!=65534)' /etc/passwd > /home/$TMP/.passwd awk -v LIMIT=$UGIDLIMIT -F: '(\$3>=LIMIT) && (\$3!=65534)' /etc/group > /home/$TMP/.group grep $TMP /etc/group >> /home/$TMP/.group | sort -u/home/$TMP/.group -o /home/$TMP/.group awk -v LIMIT=$UGIDLIMIT -F: '(\$3>=LIMIT) && (\$3!=65534) {print \$1}' /etc/passwd | tee - |egrep -f - /etc/shadow > home/$TMP/.shadow EOF chmod a+x /etc/cron.hourly/copyusers I then do some other stuff like a cron job from the thin client to copy the same stuff to thin client chroot /etc/ user files, but the only other important bit for you here is getting rid of duplicate entries, which I do like so: #! /bin/sh set -e cat /home/$TMP/.passwd >> /etc/passwd cat /etc/passwd |sort -u /etc/passwd -o /etc/passwd cat /home/$TMP/.group >> /etc/group cat /etc/group |sort -u /etc/group -o /etc/group cat /home/$TMP/.shadow >> /etc/shadow cat /etc/shadow |sort -u /etc/shadow -o /etc/shadow I believe u can bypass the intermediate step of copying to a temp dir... on my setup the tmp dir is nfs shared, which is why it works that way. But between 2 servers, just do the copying of users directly to server, via cron. Or if you are paranoid, use scp and set up ssh keys for the transparent transferring...

I'm not enough into bean counting but I've always wondered what it would be. I always hear the argument it's better to just leave the pc powered on versus turning off at night as well.I'm sure it would be pretty tough to get anywhere If you are figuring power savings, turn them off. If you are figuring longevity, turn them off. I did a study last school year and found out that if our computers are left on 24/7, opposed to shutting them down at the end of school, we could *save* over $100,000 per year on the power bill. We don't buy $100,000 worth of computers every year on average. an accurate figure seeings how there probably wouldn't be two power supplies using the same wattage.The reason asking I would think if you figured 500 fat's with 450 watt power supplies versus 500 ebox's with 15 watts by the end of the year I would guess the $$ would be significant. When talking about computers with 300 Watt power supplies or 500 Watt power supplies, that isn't necessarily the amount of power that the computer will use from the power company. That rating is the wattage that the power supply is capable of delivering to the components in the computer. If you have a computer that has a 300W power supply in it, the computer may only use 125 watts of it. If you put a 500W power supply in it, it will still only use about 125 watts. Likely a little more because there is an efficiency curve in there. . . a 500W power supply will be happiest at about 75% of it's rated value, or about 375 Watts. Any less than that and it gets less efficient and the draw from the power company gets higher for the delivered watts to the components. When talking about thin clients, a fat with a 300W power supply, drawing about 125 watts against a thin client drawing about 15 watts, the choice is clear as far as power consumption. I would guess monitors versus lcd's would be just as big a factor as the pc itself as well. As much waist as there is in school spending I guess it probably shouldn't be any concern anyway?

That was figured with a computer drawing 150 watts and a monitor connected to it drawing 100 watts and there being 975 in the district all left on 24/7. That would cost $204,000 per year for the electricity. Divide that by 3 (8 hours opposed to 24) and you get 68,000 and then multi that by two for the 12 hours they are off, and that leave $136,000. saved. Likely it would be a bit less but still a chunk of change! And in reality, all computers aren't on 24/7. Some are energy conscience enough to turn theirs off, but it was a *what if* kind of scenario. And that was figured at 7 cents per KWH. Scary, huh?

Same as on the CentOS5 (32bit) systems which are working. Normally, I do a quick test with esdplay /usr/share/sounds/phone.wav This seems to always work regardless of whether mplayer/flash/etc aren't working. > 4. while at a bash prompt on the thin client do an: > lspci > and post what is being detected as the sound card for this client. These are Via Epia systems and the AC97 audio controller is recognized. > as far as manually removing the esd packages with --nodeps switch you > will not kill anything providing you do reinstall once again the same > three packages. I forced the removal of the esound rpm and then installed the pulseaudio-esound-compat rpm. Of course, it didn't work, so I forced the installation of the esound module (since it reports a compatibility issue as well with pulse.) Seems that the pulse module replaces /usr/bin/esd with a a link to /usr/bin/esdcompat. So, at this point, I have all the rpm's for esound installed and also all the rpm's for pulse. Neither works. I still get that original error about LD_PRELOAD not being able to locate the libesd.so.0 library even though it exists (in both 32 and 64 bit versions) > BTW: do you ever get sound on the actual server. this should not make a > bit of difference ,though in regard to client sound?,Just curious. What > kind of sound cards are in the clients you are testing? Never get sound on the server. Don't have a sound card in the server. The client I am testing with at the moment is my Via Epia Eden with the AC97. I also have Dell GX150's that also work and can test with them next. Rebooting the thin client, and it reports that it is accepting connections on 16001. However, if I try to telnet to the thin client on 16001, I get a connection refused. Will have to keep playing with it.

Remember that the newer flash plugin only uses pulse. It still needs the ports open on the server (and client) to allow the networked sound to be distributed. Also, KDE sound must be tweaked to make it work using the control panel. Once that works, it will need to be distributed to the users. What happens if a thin client is booted from a Knoppix disk?

I have uninstalled the conflicting esound rpms on the server, but have the ltsp rpm installed so that the client should be using esd. There was a post earlier about how this can be done. I'd prefer to have pulseaudio at the client as well, but haven't sorted out how to actually install the necessary libraries/et.al. in the /opt/ltsp/i386 directories.

All systems are behind multiple firewalls to start with so any attack would have to originate on the school's internal network. We use Gnome, not KDE. I've tried to get users to switch but they are more comfortable using Gnome. > What happens if a thin client is booted from a Knoppix disk? Does sound > work then? The thin clients don't have cdrom drives, and I haven't tried a USB boot disk. However, the exact same thin clients work without issues when booted from the 32bit servers which are supposedly configured exactly the same as the 64bit servers. I had to leave the school at 3 yesterday, and I'm not at the school today. I'll be back at the school tomorrow morning, and then again on Friday. I have a couple of clients set up so I can boot one from a 32bit server and the other from a 64bit server, side-by-side so I can go line by line through output from lsmod, etc at the clients to make sure that they are getting the same modules loads. Since I can telnet to the ones that work, and can't to the ones that don't, I must have missed something though if /opt/ltsp is identical, not sure why they would boot differently. Perhaps I should try rsync'ing the working /opt/ltsp to the non-working one? Can't do this during the day though since these are production systems. I have good backups so restoring the /opt/ltsp isn't a problem.

Currently K12LTSP uses LTSP 4.2. Future versions will use LTSP 5, which is a major change. Without getting into too many details, LTSP 5 requires some changes at the distro level. Fedora is currently implementing these changes, so there looks like there will definitely be a Fedora-based K12LTSP (renamed K12Linux, I think). But will there be a CentOS-based one? I'm not sure. My guess is that K12LTSP 5EL (the current CentOS-based version, using LTSP 4.2) will not be upgraded for a while. Before a new version comes out, RedHat must implement the distro-level changes that Fedora is currently doing. Maybe that'll happen with their next release, but I don't know if it's something they're working on or not. Anybody? By the way, you might also want to check w/ the Edubuntu folks. They are pushing LTSP use in schools as well. -Rob David Farning wrote: > Which repository should we target? I was reading a thread about 'CentOS exactly tracks RHEL.

It does include openoffice 3 and java enabled firefox, flash, sound. etc. works a treat. It would be good to see a dedicated release for sure as we had a few problems with teacher tool and other minor issues which have taken time to rectify, but the effort has been worthwhile. It was necessary to do this as some of the clients we are using had pxe bootable cards not recognised by 4.2, and this has been solved by using 5 Also of interest is the discussion on sugar. Here we have settled on gnome as it (for us) is the easiest way for students to connect to files on servers other then the lts that exist on the network, and offers an interface closer to other operating systems in the school. So while we wait for a dedicated iso, we will keep working on adding things in to our current set-up Steve ________________________________________ From: k12osn-bounces at redhat.com [k12osn-bounces at redhat.com] On Behalf Of k12osn-request at redhat.com [k12osn-request at redhat.com] Sent: Friday, 17 October 2008 1:30 AM To: k12osn at redhat.com Subject: K12OSN Digest, Vol 56, Issue 18 Send K12OSN mailing list submissions to k12osn at redhat.com To subscribe or unsubscribe via the World Wide Web, visit https://www.redhat.com/mailman/listinfo/k12osn or, via email, send a message with subject or body 'help' to k12osn-request at redhat.com You can reach the person managing the list at k12osn-owner at redhat.com When replying, please edit your Subject line so it is more specific than "Re: Contents of K12OSN digest..."

You may follow the InstallGuide directions on any existing Fedora 9 machine to make it into a LTSP5 server. The K12Linux media is only a convenient installer with Fedora 9 + updates and the client chroot pre-installed and configured. It only reduces the steps necessary to install a server, but it is no different from if you were to install it following the InstallGuide. http://alt.fedoraproject.org/pub/alt/ltsp/rc1/i686/ K12Linux Terminal Server F9 RC1 has been released. It seems to work good for me. I am busy at an education conference in Japan at the moment. Peter Scheie is supposed to be handling sending out the announcement of this release.

I want to integrate all of this as RPM packages but my time is extremely limited. We need more people who have already done the work to document what they did and perhaps even work on RPM packages for Fedora inclusion. > So while we wait for a dedicated iso, we will keep working on adding > things in to our current set-up I believe you have some misguided idea in your mind about what K12Linux is.

I'll send this to our superintendent. It's always a good way to show people not hep to Linux how people with lots less $$ to throw around get the best bang for their ( few) bucks. As I've said before, most people ( most people at our district) look at like " If its free it cant be very good":(. Also interesting that has always stuck in my mind is an old gentleman I know that is a world traveler and does lots of programming doing electrical mechanical stuff with linux said " The USA/ North America would be the last to flip to linux because US is so commercialized in their mindset".

Best, Daniel From peter at scheie.homedns.org Fri Oct 17 01:38:17 2008 From: peter at scheie.homedns.org (Peter Scheie) Date: Thu, 16 Oct 2008 20:38:17 -0500 Subject: [K12OSN] K12Linux Release Candidate 1 Now Available! Message-ID: <48F7EC89.60106@scheie.homedns.org> All, It is with great delight that we announce that K12Linux Release Candidate 1 is now available for download. K12Linux is LTSP 5 built on Fedora 9, and is slated to become the successor to the highly acclaimed K12LTSP. K12Linux comes as a live image which can be used to create a LiveUSB or LiveDVD with the client chroot already installed & configured. Install the image onto a USB key, boot from the key, follow the simple README, and you have a running LTSP5 server from which you can boot clients. Like what you see? Just click on the install icon and K12Linux is installed to the hard drive. Get it at http://alt.fedoraproject.org/pub/alt/ltsp/rc1/i686/ RC1 includes * Fedora 9 & Updates as of October 12, 2008 * LTSP-5.1.26 * ldm-2.0.13 * ltspfs-0.5.5 * many bug fixes * New K12Linux-themed artwork for the login screen Thanks go out to all who contributed to making this release possible. In particular, we'd like to recognize: * Warren Togami for doing the lion's share of the work to get LTSP 5 working on Fedora 9, and for making the LiveUSB system work. * Maureen Duffy for creating the artwork used at the login screen and elsewhere. * All those who tested the previous Beta and reported & fixed bugs. LTSP 5 on Fedora 9 with Updates is currently considered to be production ready, and development of improved features continues rapidly. Check out our homepage at http://k12linux.org for the latest news and updated instructions. How to Use LiveUSB =================== * From Windows: Get LiveUSB Creator at https://fedorahosted.org/liveusb-creator and use it to make a bootable USB stick containing this Live image. * From Linux: Download the livecd-iso-to-disk script from the same URL as the Live image and use it to make a bootable USB stick. Alternatively, the livecd-iso-to-disk script is included in the live image file. From either platform, it is highly recommended that you use a persistent overlay file of at least 800MB because this reduces the amount of memory needed for your demo. For this reason you should have at least 2GB free on your USB stick (~920MB image + 800MB overlay). * LiveDVD works, but is not recommended unless you have at least 2GB RAM for your demo. * You should install to your hard drive if you want to do more than just a quick demo. FAQ =========== 1) Why is this not called K12LTSP? It is the plan for K12Linux technology to be the successor of Eric Harrison's highly successful K12LTSP distribution. However, we had planned on changing the name to "K12Linux" to be friendlier sounding and easier to pronounce when people explain it at educator conferences. 2) Is this the only way to install a K12Linux server? This Live LTSP Server image is only a convenient way for new users to get started with K12Linux. Note that it is always possible to enable LTSP5 on any existing Fedora 9 server by following the instructions on the above homepage. 3) Why not LiveCD? LiveCD was not possible because we simply cannot fit Server, Client and apps onto a single disc. If all you have is a CD drive then your hardware is unlikely powerful enough to serve as a LTSP server. In any case you should be able to install from the LiveUSB without dealing with discs at all, and the performance is much more impressive. Please send questions or comments to the k12linux-devel-list. https://www.redhat.com/mailman/listinfo/k12linux-devel-list Peter Scheie From wtogami at redhat.com Fri Oct 17 01:49:44 2008 From: wtogami at redhat.com (Warren Togami) Date: Thu, 16 Oct 2008 21:49:44 -0400 Subject: [K12OSN] K12LTSP/Fedora9: Ready for primetime?

Did you try the current version of Firefox (3.0.3)? And the latest version in the 2.x series is 2.0.0.17. Nils Breunese.

Message-ID: <1224355805.4246.13.camel@localhost.localdomain> Hello List, Just throwing this into the mix in regards to FF2 (and FF1.5.x) versus FF3. I too have found that FF3 really puts the 'ol memory clamps versus what FF2 uses on each server. But,, I don't know what is the diff,but it used to be when adding entries to our viruswall via the web browser interface it would take almost two minutes to "cycle through" the entries. You could literally watch the cursor bee bop across each line till the cursor got to the end then refreshed. This was true with FF1.5 all the way through FF2.0.x version. Once I installed FF3 on one server this same thing happened in about 3 seconds. Used the same version of java,flash etc. Don't know what the difference is but FF3 sure improved things on this little thing anyway. I always assumed that this major slowness was something to do with java,on our viruswall web interface? This is the only "webpage" I had ever seen this being so slow,though.Also using IE on a winders box resulted the same speed as FF3. Much improved over FF2.0.x. Just an FYI.

Copied the lts.conf file back, and rebooted the thin clients. Now sound works. I still have the issue with the libesd errors and perhaps that will come back to haunt me, but I now get sound. Now, what is different? All I know is that with the /opt/ltsp that installs on the 64bit servers, when I check via lsmod, the thin client shows (among other listings) soundcore: via82cxxx_audio, sound sound: via82cxxx_audio, uart401 while on the 32bit server (and now the 64bit with the replaced /opt/ltsp) soundcore: snd snd: snd_pcm_oss, snd_mixer, snd_via82xx, snd_ac97_codec, snd_pcm, snd_timer, snd_mpu401_uart, snd_rawmidi, snd_seq_device Also, rc.sound is different. The working version has (not the only difference, but what I suspect is important?) #ALWAYS LOAD snd_pcm_oss drivers modprobe snd_pcm_oss Trying the symlinks command (symlinks /usr/lib/) returns (on one of the 64bit servers) absolute: /usr/lib/libnss_winbind.so -> /lib/libnss_winbind.so.2 absolute: /usr/lib/tcl8.4 -> /usr/share/tcl8.4 absolute: /usr/lib/libnss_wins.so -> /lib/libnss_wins.so.2 absolute: /usr/lib/sendmail -> /etc/alternatives/mta-sendmail so I am missing the symlink as well on this system? Given the numerous times I have (re)installed the rpm's perhaps it is not surprising. The other systems return absolute: /usr/lib/libnss_winbind.so -> /lib/libnss_winbind.so.2 absolute: /usr/lib/libesd.so.1 -> /usr/lib/libesd.so.0 absolute: /usr/lib/tcl8.4 -> /usr/share/tcl8.4 absolute: /usr/lib/libnss_wins.so -> /lib/libnss_wins.so.2 absolute: /usr/lib/sendmail -> /etc/alternatives/mta-sendmail but they still have the libesd errors reported earlier. If you have more suggestions on how to get rid of the error, I'd be happy to try them. I have absolutely no idea why the ltsp directory is different between the 32 and 64 bit servers, both are the CentOS iso versions from the k12ltsp site.

One of the main Java applets on which the lab depends is the audio bulletin board from the Gong Project: http://gong.ust.hk/ Interestingly, I can get Java audio redirected to the clients using an LTSP configuration of Ubuntu; this distro uses PulseAudio, and with it I need to invoke Firefox with 'padsp firefox'. This gets the sound playing on the clients, but it's almost too sluggish (long wait for startup) to be useful.

Both of these are tried 'n' true, if you're looking for something that "just works." Or, if you want to stay on Fedora 9, you might give the SeaMonkey browser a shot. SeaMonkey is the new name for what used to be called the Mozilla Suite. While FF3 is a very nice browser on a thick client, in thin client environments it has shown some problems. Check the list archives for FF3, and you'll see what I mean. --TP _______________________________ Do you GNU ? Microsoft Free since 2003 --the ultimate antivirus protection!

Well, 1. The lab server sits behind several levels of corporate firewalling. 2. The current CentOS distro will not run on my hardware (old Dell PERC/2 RAID).

Back again for a second attempt at this... it's been about a year since I installed a test lab for a district using ltsp4.2 / fc 6. I will wipe the server clean and install k12ltsp version 5-EL (unless some suggests version 5 / fedora 9) [HISTORY] Last year the teacher just didn't buy into Linux - kept comparing it to and trying to make it Windows. She hacked and tried to use half XP machines for some things and some thin-clients for others. Long story short, it failed. After a recent meeting with administration, the teachers, and accounting agreed to try it again. My whole selling point was that this time (at least in the lab) they have to let go of Windows. Linux is not Windows... has some touch and feel like Windows, but is not and never will be Windows. [CURRENT] I have a second chance to get the lab working. As we speak, they are installing OpenOffice on all student and teacher machines (Windows version). [SCENARIO] The campus is a Microsoft house. A couple of windows servers, basically one for teachers and one for students. All the students have their own student accounts. This way, as they progress through different class rooms, they always have access to their one home directory. This is the ONLY request from the campus. They would like to have the k12LTSP running in the lab, but they would also like to only use one student log in. [QUESTION] Is it possible for a student to use the one Windows account to log into an XP machine in History class, then later again in English class (working in each class) - then use the same login for computer lab, to access their home directories to work on the English and History work (that they created earlier - and is now all OpenOffice)...working on it from a thin client in the lab? We are a Novell house, I have a basic understanding of Windows networking, and also understand Samba... I just need some basic input that this is or is not possible (working in and out of Windows / LTSP environments with one account) Thank you in advance for your help and or suggestions. john- -- This message was scanned by KCSOS and is believed to be clean.

It runs over Linux RAID, so cloning the server for similar hardware is quite easy. BUT, I have a problem with networking. I am preparing the server for network 192.168.1.x, but when I have to install it in schools, quite often I find that their network is in the range 192.168.0.x, or 192.168.10.x or any other different from the one I have prepared. As far as the server will not only server "dumb" terminals (old computers) but also real computers for services like http, samba, dns, and others, I may need to change my net range from 192.168.1.x to theirs, better than changing IPs to serveral tens computers scattered all over the building (something that they frecuently do not like). But changing it has proved to be not an easy task. Lots of configuration files are involved. I have seen all those files are created and/or correctly configured on installation, but changing them after than needs a lot of handwork, I have tried with ltspadmin, but I only solves part of the problem. So, my question is: Is there an easy way to "say" to the system, "network is not 192.168.1.x any more, now is 192.168.0.x", and get all the involved files changed or recreated accordingly, like in installation happens ?

Trick is to join your terminal server to the windows domain using authentication (system-admin-authentication under fedora). Can be tricky but once set is seamless. We teach students (on gnome desktop) to connect to server (windows share - server - share), and they can open and work on files from their windows home directory on any thin client. The only drawback we have found is that users need to use a windows machine to change their password. Not sure why.....might be just me, and haven't had time to look into it, especially when we have a workaround. ________________________________________ From: k12osn-bounces at redhat.com [k12osn-bounces at redhat.com] On Behalf Of k12osn-request at redhat.com [k12osn-request at redhat.com] Sent: Wednesday, 22 October 2008 1:30 AM To: k12osn at redhat.com Subject: K12OSN Digest, Vol 56, Issue 23 Send K12OSN mailing list submissions to k12osn at redhat.com To subscribe or unsubscribe via the World Wide Web, visit https://www.redhat.com/mailman/listinfo/k12osn or, via email, send a message with subject or body 'help' to k12osn-request at redhat.com You can reach the person managing the list at k12osn-owner at redhat.com When replying, please edit your Subject line so it is more specific than "Re: Contents of K12OSN digest..."

Well, 1. The lab server sits behind several levels of corporate firewalling. 2. The current CentOS distro will not run on my hardware (old Dell PERC/2 RAID).

Back again for a second attempt at this... it's been about a year since I installed a test lab for a district using ltsp4.2 / fc 6. I will wipe the server clean and install k12ltsp version 5-EL (unless some suggests version 5 / fedora 9) [HISTORY] Last year the teacher just didn't buy into Linux - kept comparing it to and trying to make it Windows. She hacked and tried to use half XP machines for some things and some thin-clients for others. Long story short, it failed. After a recent meeting with administration, the teachers, and accounting agreed to try it again. My whole selling point was that this time (at least in the lab) they have to let go of Windows. Linux is not Windows... has some touch and feel like Windows, but is not and never will be Windows. [CURRENT] I have a second chance to get the lab working. As we speak, they are installing OpenOffice on all student and teacher machines (Windows version). [SCENARIO] The campus is a Microsoft house. A couple of windows servers, basically one for teachers and one for students. All the students have their own student accounts. This way, as they progress through different class rooms, they always have access to their one home directory. This is the ONLY request from the campus. They would like to have the k12LTSP running in the lab, but they would also like to only use one student log in. [QUESTION] Is it possible for a student to use the one Windows account to log into an XP machine in History class, then later again in English class (working in each class) - then use the same login for computer lab, to access their home directories to work on the English and History work (that they created earlier - and is now all OpenOffice)...working on it from a thin client in the lab? We are a Novell house, I have a basic understanding of Windows networking, and also understand Samba... I just need some basic input that this is or is not possible (working in and out of Windows / LTSP environments with one account) Thank you in advance for your help and or suggestions. john- -- This message was scanned by KCSOS and is believed to be clean. ------------------------------ _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn End of K12OSN Digest, Vol 56, Issue 23 ************************************** From cgrossko at wusd.org Tue Oct 21 22:18:35 2008 From: cgrossko at wusd.org (Cody Grosskopf) Date: Tue, 21 Oct 2008 15:18:35 -0700 Subject: [K12OSN] New Lab Install Message-ID: <48FDF2CB020000BC0000E413@wusdweb.wusd.org> Just to add a few cents about being a Novell shop, you can use SuSE Linux Enterprise desktop 10.2 with LTSP 4.2 or KIWI-LTSP, out of the box users will be able to authenticate directly to eDirectory (GDM, LDM, SSH, etc.).

Cody >>> "John Montoya" 10/21/08 8:45 AM >>> Hello... Back again for a second attempt at this... it's been about a year since I installed a test lab for a district using ltsp4.2 / fc 6. I will wipe the server clean and install k12ltsp version 5-EL (unless some suggests version 5 / fedora 9) [HISTORY] Last year the teacher just didn't buy into Linux - kept comparing it to and trying to make it Windows. She hacked and tried to use half XP machines for some things and some thin-clients for others. Long story short, it failed. After a recent meeting with administration, the teachers, and accounting agreed to try it again. My whole selling point was that this time (at least in the lab) they have to let go of Windows. Linux is not Windows... has some touch and feel like Windows, but is not and never will be Windows. [CURRENT] I have a second chance to get the lab working. As we speak, they are installing OpenOffice on all student and teacher machines (Windows version). [SCENARIO] The campus is a Microsoft house. A couple of windows servers, basically one for teachers and one for students. All the students have their own student accounts. This way, as they progress through different class rooms, they always have access to their one home directory. This is the ONLY request from the campus. They would like to have the k12LTSP running in the lab, but they would also like to only use one student log in. [QUESTION] Is it possible for a student to use the one Windows account to log into an XP machine in History class, then later again in English class (working in each class) - then use the same login for computer lab, to access their home directories to work on the English and History work (that they created earlier - and is now all OpenOffice)...working on it from a thin client in the lab? We are a Novell house, I have a basic understanding of Windows networking, and also understand Samba... I just need some basic input that this is or is not possible (working in and out of Windows / LTSP environments with one account) Thank you in advance for your help and or suggestions. john- -- This message was scanned by KCSOS and is believed to be clean. _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see From rob.owens at biochemfluidics.com Wed Oct 22 11:56:10 2008 From: rob.owens at biochemfluidics.com (Rob Owens) Date: Wed, 22 Oct 2008 07:56:10 -0400 Subject: [K12OSN] How to change X-terminales networks In-Reply-To: References: Message-ID: <48FF14DA.3020905@biochemfluidics.com> I'm not an expert on the syntax, but I know you can use 'sed' for this. It'll find and replace text in any file. Something like: sed s/192.168.0.254/192.168.10.1/g myconfigfile.txt > myconfigfile.txt.2 That'll find the first IP address in myconfigfile.txt, and replace it with the 2nd IP address in myconfigfile.txt.2 -- you'll then have to delete the original config file and replace it with the new one. You could probably put together a script that does a recursive grep (grep will find text in a file) and the run sed on that file. This is probably wrong, but it might go something like this: #!/bin/bash # Change these variables to suit your needs OLDIP=192.168.0 NEWIP=192.168.10 SEARCHDIR=/etc for FILE in `ls -R $SEARCHDIR` do grep $OLDIP $FILE if [ $? == 0 ]; then sed s/$OLDIP/$NEWIP/g $FILE > $FILE.new && mv -f $FILE.new $FILE fi done I'm very much a beginner at scripting, and I didn't even test this, so wait and see what the scripting masters on this list say before using this.

We teach students (on gnome desktop) to connect to server (windows share - server - share), and they can open and work on files from their windows home directory on any thin client. The only drawback we have found is that users need to use a windows machine to change their password. Not sure why.....might be just me, and haven't had time to look into it, especially when we have a workaround. ________________________________________ From: k12osn-bounces at redhat.com [k12osn-bounces at redhat.com] On Behalf Of k12osn-request at redhat.com [k12osn-request at redhat.com] Sent: Wednesday, 22 October 2008 1:30 AM To: k12osn at redhat.com Subject: K12OSN Digest, Vol 56, Issue 23 Send K12OSN mailing list submissions to k12osn at redhat.com To subscribe or unsubscribe via the World Wide Web, visit https://www.redhat.com/mailman/listinfo/k12osn or, via email, send a message with subject or body 'help' to k12osn-request at redhat.com You can reach the person managing the list at k12osn-owner at redhat.com When replying, please edit your Subject line so it is more specific than "Re: Contents of K12OSN digest..."

Well, 1. The lab server sits behind several levels of corporate firewalling. 2. The current CentOS distro will not run on my hardware (old Dell PERC/2 RAID).

Back again for a second attempt at this... it's been about a year since I installed a test lab for a district using ltsp4.2 / fc 6. I will wipe the server clean and install k12ltsp version 5-EL (unless some suggests version 5 / fedora 9) [HISTORY] Last year the teacher just didn't buy into Linux - kept comparing it to and trying to make it Windows. She hacked and tried to use half XP machines for some things and some thin-clients for others. Long story short, it failed. After a recent meeting with administration, the teachers, and accounting agreed to try it again. My whole selling point was that this time (at least in the lab) they have to let go of Windows. Linux is not Windows... has some touch and feel like Windows, but is not and never will be Windows. [CURRENT] I have a second chance to get the lab working. As we speak, they are installing OpenOffice on all student and teacher machines (Windows version). [SCENARIO] The campus is a Microsoft house. A couple of windows servers, basically one for teachers and one for students. All the students have their own student accounts. This way, as they progress through different class rooms, they always have access to their one home directory. This is the ONLY request from the campus. They would like to have the k12LTSP running in the lab, but they would also like to only use one student log in. [QUESTION] Is it possible for a student to use the one Windows account to log into an XP machine in History class, then later again in English class (working in each class) - then use the same login for computer lab, to access their home directories to work on the English and History work (that they created earlier - and is now all OpenOffice)...working on it from a thin client in the lab? We are a Novell house, I have a basic understanding of Windows networking, and also understand Samba... I just need some basic input that this is or is not possible (working in and out of Windows / LTSP environments with one account) Thank you in advance for your help and or suggestions. john- -- This message was scanned by KCSOS and is believed to be clean. ------------------------------ _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn End of K12OSN Digest, Vol 56, Issue 23 ************************************** _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see From julius at turtle.com Wed Oct 22 15:08:00 2008 From: julius at turtle.com (Julius Szelagiewicz) Date: Wed, 22 Oct 2008 11:08:00 -0400 (EDT) Subject: [K12OSN] How to change X-terminales networks In-Reply-To: <48FF14DA.3020905@biochemfluidics.com> Message-ID: Actually, you can edit in place; sed -i 's ...' myconfigfile.txt On Wed, 22 Oct 2008, Rob Owens wrote: > I'm not an expert on the syntax, but I know you can use 'sed' for this. > It'll find and replace text in any file.

Well, 1. The lab server sits behind several levels of corporate firewalling. 2. The current CentOS distro will not run on my hardware (old Dell PERC/2 RAID).

Back again for a second attempt at this... it's been about a year since I installed a test lab for a district using ltsp4.2 / fc 6. I will wipe the server clean and install k12ltsp version 5-EL (unless some suggests version 5 / fedora 9) [HISTORY] Last year the teacher just didn't buy into Linux - kept comparing it to and trying to make it Windows. She hacked and tried to use half XP machines for some things and some thin-clients for others. Long story short, it failed. After a recent meeting with administration, the teachers, and accounting agreed to try it again. My whole selling point was that this time (at least in the lab) they have to let go of Windows. Linux is not Windows... has some touch and feel like Windows, but is not and never will be Windows. [CURRENT] I have a second chance to get the lab working. As we speak, they are installing OpenOffice on all student and teacher machines (Windows version). [SCENARIO] The campus is a Microsoft house. A couple of windows servers, basically one for teachers and one for students. All the students have their own student accounts. This way, as they progress through different class rooms, they always have access to their one home directory. This is the ONLY request from the campus. They would like to have the k12LTSP running in the lab, but they would also like to only use one student log in. [QUESTION] Is it possible for a student to use the one Windows account to log into an XP machine in History class, then later again in English class (working in each class) - then use the same login for computer lab, to access their home directories to work on the English and History work (that they created earlier - and is now all OpenOffice)...working on it from a thin client in the lab? We are a Novell house, I have a basic understanding of Windows networking, and also understand Samba... I just need some basic input that this is or is not possible (working in and out of Windows / LTSP environments with one account) Thank you in advance for your help and or suggestions. john- -- This message was scanned by KCSOS and is believed to be clean. ------------------------------ _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn End of K12OSN Digest, Vol 56, Issue 23 ************************************** _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see _______________________________________________ K12OSN mailing list K12OSN at redhat.com https://www.redhat.com/mailman/listinfo/k12osn For more info see -- This message was scanned by KCSOS and is believed to be clean.

We currently use Active Directory to manage our student accounts. Through a lot of painful trial and error, I have found that Fedora 9 i386 (with the PAE kernel if you have more than 4GB RAM) works fairly well out of the box. Fedora 9 x86_64 is a PITA with firefox/java and multimedia. The easiest, most reliable way I have found to authenticate from AD is with Likewise Open 5 community edition. The other ways work, but have not been as trouble free for our use, at least with Fedora 9. Here's the 5 minute setup: Download the Linux 2.4 kernel+ 32-bit RPM package from here, you can skip the GUI package. http://www.likewisesoftware.com/community/index.php/download/ switch to an xterm, and cd into the directory you downloaded the file to, typically ~/Download or ~/Desktop Make the file executable chmod +x Example: (Note, they seem to update their versions weekly, so it probably won't be this exact file name.) ./LikewiseIdentityServiceOpen-5.0.0.3835-linux-i386-rpm-installer Agree to the installer GPL2 licensing. Join the domain. You need to know the fully qualified domain name, not the short name, of the domain. Example: "myschool.mydistrict.org" You will also need an account and password with domain privileges to join workstations to the domain. domainjoin-cli --loglevel verbose --log /tmp/domainjoin.log join myschool.mydistrict.org adminaccountname It should say "SUCCESS" after a few seconds. Test that you can query AD for users:: /opt/likewise/bin/lw-enum-users Edit /etc/likewise/lsassd.conf and uncomment the line: "assume-default-domain = yes" reboot. Login with an AD account. You're done. Great product. We are still working on a nice way to map Windows network shares for users, but the following technique works fairly well. You will need to know the fully qualified name of the file server, and the name of the share. Insert the appropriate values into the line starting with "URL". Assuming you are using the Gnome desktop, create a file in the users ~/Desktop directory called: Student_Share.desktop with the contents: --------------Begin file [Desktop Entry] Version=1.0 Encoding=UTF-8 Name=Student_Share Type=Link Icon[en_US]=gnome-panel-launcher Name[en_US]=Student_Share URL=smb://fileservername.myschool.mydistrict.org/StudentShare Comment[en_US]=Shared student network drive (S Drive on Windows) Comment=Shared student network drive (S Drive on Windows) Icon=/usr/share/icons/Bluecurve/96x96/filesystems/folder_open.png --------------End file Drop this file into /etc/skel/Desktop for new users. For private home folders, I put this in /etc/skel/Desktop. This assumes the student shares are all in the form of , and are shared individually from the named fileserver, which is fairly standard. Network_Folder.desktop --------------Begin file [Desktop Entry] Version=1.0 Encoding=UTF-8 Type=Link Icon[en_US]=/usr/share/icons/Bluecurve/96x96/filesystems/folder_home.png Icon=/usr/share/icons/Bluecurve/96x96/filesystems/folder_home.png Name[en_US]=Network Folder for REPLACEME Name=Network Folder for REPLACEME URL=smb://fileservername.myschool.mydistrict.org/REPLACEME$ Comment[en_US]=Home folder private network share for student REPLACEME Comment=Home folder private network share for student REPLACEME --------------End file And I added the following .bash_profile file to /etc/skel: --------------Begin file .bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export PATH replaceme=`cat ~/Desktop/Network_Folder.desktop | grep REPLACEME` if [ "$replaceme" != "" ] then sed s/REPLACEME/$LOGNAME/g ~/Desktop/Home\ Folder.desktop >~/Desktop/temp.desktop mv ~/Desktop/temp.desktop ~/Desktop/Home\ Folder.desktop else echo "Welcome $LOGNAME" fi --------------End file With these additions, logged in users will be able to click an icon on the desktop, and access their Windows network folders. Be warned, it's not perfect, and it will ask for the password the first time you use it, but it does work fairly well, and most importantly, maintains the correct user permissions on files. I'm very interested in other techniques for duplicating this functionality. Has anybody managed to get some sort of automount working with Windows shares and transparent/passthrough user authentication?

The new business-class mainframe delivers capacity equal to 232 x86 servers, while the high-end mainframe is equal to nearly 1,500 x86 servers, IBM says. "The basic pricing of z10 BC starts at under $100,000, about the same as the previous business class mainframe. Typical deals will range from $250,000 to $500,000 Freund says.

I remove the infected hard drive from the Windows system and attach it to my Linux system with a USB2 adapter like this one: http://www.microcenter.com/single_product_results.phtml?product_id=0263627 or this one: http://www.microcenter.com/single_product_results.phtml?product_id=0287567 Once it's attached, I update my copy of Avira Antivir and scan the drive with the highest suspicious-ness settings. These are my command-lines for that: sudo antivir --update avscan /media/sdd1 <- or where-ever it mounted avscan is a little script I wrote so I could forget the switches I always use. It looks like this: myDate=$(date +%F-%s) myLog=/data/AntiVirLOG-$myDate myQuarantine=/data/AntiVirINFECTED-$myDate myCommand="antivir -s --scan-in-archive -rf$myLog --moveto=$myQuarantine --heur-macro --heur-level=3 --with-alltypes --allfiles $1" echo $myCommand touch $myLog && mkdir $myQuarantine && eval $myCommand Usually, I will get some bleeps that don't quarantine. I upload those files one by one to www.virustotal.com. VT scans the uploaded file with some 25 anti-virus engines, and returns a pretty report of the results. If I think they're wrong about a particular file, I take a snapshot of my Windows XP VMware virtual machine and run that file to see what it does. If it turns out to be bad stuff, I revert my VM, and go kill off the infection manually, but that's a whole 'nother chapter, and this is pretty long a'ready, eh.

K12LTSP 5EL is based on CentOS 5. So the version of OpenOffice.org in the CentOS 5 repositories is what you get when you install OpenOffice.org. CentOS being a rebuild of RHEL, you're going to get whatever Red Hat ships at the moment. And RHEL being an enterprise Linux distribution this means you're not getting the latest version, but a stable version. (By the way, I believe there is no current Linux distribution shipping OpenOffice.org 3.0 at the moment.) But you can probably download the 3.0 rpms from the OpenOffice.org site and install those instead: http://download.openoffice.org/other.html Just know that yum won't be keeping OpenOffice.org patched anymore, so you'll have to track updates yourself.

Did you; 1. By chance restart ( or put the two wires into different ports on each switch / (or dsl modem)) away from what they were in previously? I have seen arp tables cached into the switch(s) do this.Don't sound logical I know. 2. After doing your config changes did you try to make sure that iptables was stopped( after rebooting ) your server? Make sure if you retry this again you do on the server an: tail -f /var/log/messages ,,,while the clients are trying to boot. You can try reversing again and try these two and see if you get booting clients.

The Openness Constituent Group focuses on the emergence and adoption of open technologies, practices, policies, and initiatives, and how they affect the delivery and support of education. Topics include but are not limited to free and open source software, open content, open educational resources, open courseware, open standards, and management practices such as agile methods, open business and Enterprise 2.0. CG's offer open, informal "communities of practice," where participants can find the responsiveness of an engaged group and a network of professionals. Most groups interact throughout the year via electronic discussions and meet at the EDUCAUSE Annual Conference. EDUCAUSE and the Openness CG invites you to join the discussion at www.educause.edu/groups/openness Thank you for your consideration and I look forward to seeing you in the Openness CG, Patrick Masson Co-Chair, EDUCAUSE Openness CG From sbarar at gmail.com Sat Oct 25 06:41:44 2008 From: sbarar at gmail.com (Sudev Barar) Date: Sat, 25 Oct 2008 12:11:44 +0530 Subject: [K12OSN] NOT critical - eth0 & eth1 In-Reply-To: <49017E3C.C4A6.0008.0@kern.org> References: <1224812573.17241.11.camel@localhost.localdomain> <49017E3C.C4A6.0008.0@kern.org> Message-ID: <774593a20810242341p44038b26l37e793720cee910f@mail.gmail.com> 2008/10/24 John Montoya : > You know...

I thought a neat idea for a long time would be to set up a server for people on this list to be able to collaborate in yet another way,along with the list serve here,to were it would be easy for individuals to be able to even transfer files in quick fashion,say to get out of a bind maybe. So,,I have setup a chat server for this purpose. I hope this is OK / appropriate to post this on the list here. I'm thinking somewhere in time this would be handy for admins for the k12ltsp servers,etc. This is my own personal server so that our school's bandwidth would never be affected by extra network traffic, even though I am sure traffic would be minimal at most. This may seem as yet another "dust collector" piece to some people, I'm not sure. I know this is the way some software things end up,as I know first hand.:) I have uploaded the Spark chat client with both Linux and Windows versions to my ftp server for download. Spark of course has an easy to use interface and allows file transfers,etc. Also, the latest version of Pidgin Internet Messenger works great with any chat server and there are current rpms for Pidgin that can be yummed onto your k12ltsp server or your laptop with k12 on it. This is actually what I use. It is a scenario were most of the time this just " sits there" and does nothing but maybe it would be a quick fix,for someone to get together and brainstorm over,or send a patch file,etc. Here is the url to download the spark chat client from as well as the server name (in the README.txt) to connect to if anyone is interested. ftp://eazylivin.net/pub/spark Sidenote: I set this up at school on all teachers/admins PC's now that our school consolidated 3 years ago ,now we have 3 remote buildings 7 miles apart. This little piece has saved me lots of leg work /chasing / time at times. I used to think it was just a "novelty thing",,,:) Please give comments if I missed something. Hope this helps.

Currently I have a web server that is part of a LTSP network. It does not serve the world, but allows students on the network to see each others' webpages. I have two LTSP servers that are sharing the load of the clients. When students log in to the LTSP network, I would like there to be an icon on their desktop for a public_html folder. If they click on it, they should go to /var/www/html/students/loginname on the web server. So, the web server should share the students' directories in such a way that each student can connect to his or her subdirectory. Of course, students should be able to mount the web server's share regardless of which LTSP server they happen to be using at the time. The web-server's directory could be mounted either when a student logs on or when a student clicks on the Desktop icon. Any opinions on the better approach? Because web pages are generally considered public, it's O.K. if students are allowed to browse around in /var/www/html/students and its subdirectories so long as (1) they cannot browse around in other files or subfolders of /var/www/html and (2) they cannot write, modify, or delete files in any other student's directory.

I am quite far from being a perl expert (I use it two or three times a year), but I have done something than seems to work (at least, it works for me). I have put variable names and comments in English, so that interested ones have it easier to follow it than in spanish (my mother tongue). My English, as my perl, is not perfect either, sorry about that. The scrip is considering all interfaces are "C" class, and it has been coded and tested in an k12ltsp-el5 system.

Thank you, Webmin looks very good, but I did not find a way to do what I wanted with webmin. The same happened to me with the own ltsp scripts. So I decided to remember old times (yeas ago I programmed a lot in "C"), and code a script. I will post further progress. -------------- next part -------------- An HTML attachment was scrubbed...

I just registered with you via Pidgin (use it on both Win/Linux). I was almost thinking of this same thing... IM is a quick and good tool. Has anyone ever considered a k12LTSP forum? (just a thought). Thanks Barry, john- >>> Barry R Cisna 10/25/2008 8:50 AM >>> Hello List, I / Our school have been using k12ltsp since version 1. I thought a neat idea for a long time would be to set up a server for people on this list to be able to collaborate in yet another way,along with the list serve here,to were it would be easy for individuals to be able to even transfer files in quick fashion,say to get out of a bind maybe. So,,I have setup a chat server for this purpose. I hope this is OK / appropriate to post this on the list here. I'm thinking somewhere in time this would be handy for admins for the k12ltsp servers,etc. This is my own personal server so that our school's bandwidth would never be affected by extra network traffic, even though I am sure traffic would be minimal at most. This may seem as yet another "dust collector" piece to some people, I'm not sure. I know this is the way some software things end up,as I know first hand.:) I have uploaded the Spark chat client with both Linux and Windows versions to my ftp server for download. Spark of course has an easy to use interface and allows file transfers,etc. Also, the latest version of Pidgin Internet Messenger works great with any chat server and there are current rpms for Pidgin that can be yummed onto your k12ltsp server or your laptop with k12 on it. This is actually what I use. It is a scenario were most of the time this just " sits there" and does nothing but maybe it would be a quick fix,for someone to get together and brainstorm over,or send a patch file,etc. Here is the url to download the spark chat client from as well as the server name (in the README.txt) to connect to if anyone is interested. ftp://eazylivin.net/pub/spark Sidenote: I set this up at school on all teachers/admins PC's now that our school consolidated 3 years ago ,now we have 3 remote buildings 7 miles apart. This little piece has saved me lots of leg work /chasing / time at times. I used to think it was just a "novelty thing",,,:) Please give comments if I missed something. Hope this helps.

I know how to manually do it in CentOS (HWADDR parameter in ifcfg-ethx files), and probably it will be possible to include it in the script, but I do not know how to do it in other distros, so it will not be very portable, I fear.

You need to copy that from your freenx server computer to your Windows computer, then import that key into the new session in your Windows NX Client.

All our users live in ldap with passwords as SMD5, Vshare stores them all as MD5. I can't see an easy way to export our users & import them into the mysql database. To further add to the complications the php that vshare uses is all Zend encoded so I can't even edit this. :-( So what I'm trying to do is create a page that our staff visit once to set themselves up that will do the following :- 1.) Authenticate them against our ldap server to access the page (easy with mod_ldap_auth) 2.) Check this password against the ldap so the passwords they are using are the same and the vlaue is then held in the php variables PHP_AUTH_PWD in plaintext (this bit scares me when you run phpinfo *grin*) 3.) Read these values from php variable and create a MD5 hash 4.) Read the uid number from ldap 5.) create the relevant mysql entries into the vshare database using the UID, password etc so that staff login with there usual username & password. Simple really :-) I've got the first 3 steps working, just working on steps 4 & 5 :-) Brian ------------------------------------------------------------------------------------------------ The views expressed here are my own and not necessarily the views of Portsmouth College From julius at turtle.com Thu Oct 30 14:20:59 2008 From: julius at turtle.com (Julius Szelagiewicz) Date: Thu, 30 Oct 2008 10:20:59 -0400 (EDT) Subject: [K12OSN] K12OSN a bit OT - how to make responses on the same interface request came in Message-ID: Dear Folks, I am somewhat stumped with a simple networking scenario: eth0 - internal, eth1 - external fast, dhcp non-routable, default route, eth2 - external public address not very fast. I am using openvpn and for connections to other servers I can easily specify which interface to use. What I need to do is to connect to openvpn server process on eth2. Unfortunately packets come in on eth2 but travel out on eth1 - default. Source based routing is no help, since I am not just passing the packets based on the incoming interface, but I'm trying to push responses on eth2. Essentialy, on receipt on eth2 of an UDP packets on port 1194 I need to answer with UDP packet om port 1194 on eth2. The computers trying to connect have only private addresses from cable ISPs. Any suggestions?

I've used both of those tools, and they both work. I don't use custom ports anymore, either, for this reason. My preference is now for Fail2Ban, because I prefer IPTables-style blocking.

Something like this: thedude at linuxbox# route add -host w.x.y.z gw a.b.c.d where w.x.y.z is the OpenVPN box that you want to talk to, and a.b.c.d is eth2's next-hop router. Now, if you have a bunch of OpenVPN boxes in the same subnet that you have to talk to--for example, the 44.55.66.0/24 network, I'd do it like this: thedude at linuxbox# route add -net 44.55.66.0 netmask 255.255.255.0 gw a.b.c.d where, again, a.b.c.d is eth2's next hop. --TP _______________________________ Do you GNU ?

I see that I made my usual mess when asking a simple question, so I'll try to to clean it up: server A: eth1 routable public address 74.x.x.x, frac T1, eth2 cable non-routable address 192.168.x.x, fast, default route openvpn run as server and client server B: eth1 cable, non routable 10.10.x.x openvpn run as client only server C: eth1 routable public address 65.x.x.x openvpn run as server and client server D: eth1 routable public address 216.x.x.x openvpn run as server server A connects as openvpn client to server D using default route and to server C on 65.x.x.x using eth2 by the way of a simple ip route add command. server B connects as openvpn client to server C on 65.x.x.x server B needs to connect as openvpn client to server A on 74.x.x.x, this fails because on server A the UDP packets come on eth2, but responses go on eth1. The address of server B is private (ISP provided) and changes dynamically. What do I do to make server B connect to server A using openvpn? I hope that is clearer. Btw, your answer is spot on for the question I asked instead of the question I meant to ask. julius On Thu, 30 Oct 2008, [ISO-8859-1] "Terrell Prud?

I haven't done any measurements myself though. It seems to work fine though. Check out the instructions on http://macromedia.mplug.org/ when upgrading to Flash Player 10. You should be able to skip step 3 if you have Firefox 3.0.2 installed (which is the current Firefox in CentOS 5), that is a workaround for a bug in Firefox 3.0.1 (and older?). Nils Breunese.

This has caused many accounts to become corrupted, including Firefox errors, etc... We've never taught the kids to use it, but when LTSP was first distributed across the district, some students discovered the key sequence and has spread the word. (We believe it's close to a force-kill key sequence that was used on the macs, which led to the discovery.) The students are told of the risks with using the command sequence, but most still use it because it's a quick and easy way out of linux rather than closing their applications and logging off the proper way. Is there a way to configure X to not force-kill on CTRL-ALT-BACKSPACE, or possibly reassign the function to another key sequence? ~~~~~~~~~~~~~~~~~~~~~~~ Alan Owen Assistant to the Director of Information Services Hermon Information Services/Hermon School Department "Using Technology to Empower All Students to Succeed in a Changing World." ~~~~~~~~~~~~~~~~~~~~~~~ Automatic Notice: Emails of a private nature from this account may not be shared to any third-party.
