| 03:50 | <asmok> Hello, it's been a while ;-)
| |
| 03:51 | About LTSP-Cluster: is it possible to use two nics in every server or should there be only one in every server?
| |
| 03:54 | I have now two nics. My root server is 10.04 Beta 2. TC boots just fine, but I got troubles with 'ltsp-cluster-control/Admin/admin.php' page. It is just empty in browser.
| |
| 03:55 | Log from ltsp-cluster-lbserver: Start NodesMonitor...

| 03:55 | Start MGMT Service...
| |
| 03:55 | Start HTTP Server...
| |
| 03:55 | Cannot retrieve node 'cluster01', error:<class 'socket.error'>
| |
| 03:56 | I just try to follow my own howto, which is for one nic in every server :)
| |
| 03:57 | I know, it is another lazy sunday afternoon, but I hang around...:) PG's new album is just great :)
| |
| 04:03 | See this image: is there something wrong? http://www.arkki.info/howto/Wiki/LTSP5-Testausta/Lucid-ltsp-cluster/ltsp-cluster_01.jpg

| |
| 04:17 | Well, you know this LTSP-Cluster thing is little bit hard to do because of lack of good documentation...
| |
| 04:21 | And yes, in that image root server's eth0 is '192.168.1.102', I do use now '192.168.1.210' - TC boots just fine.

| 09:52 | <markit> hi, I want to update the chroot, but I'm confused by the command sequence. In LTSPManual.pdf I've read that "export LTSP_HANDLE_DAEMONS=false" is done AFTER being in chroot, while in https://help.ubuntu.com/community/UbuntuLTSP/UpdatingChroot is done BEFORE. What is correct?

| 10:06 | emence has joined #ltsp | |
| 10:06 | <markit> well, don't answer it all together ;)
| |
| 10:07 | maybe many of you are from timezones where is very early morning now
| |
| 10:07 | <emence> Anyone have a problem with a "No root Device Found. Sleeping forever" bootup error on a HP t5545
| |
| 10:07 | its booting PXE boot
| |
| 10:07 | it finds the pxe image, and starts to load then dies
| |
| 10:08 | <markit> emence: I've not such a thin client. Does it work fine with a different one? I mean, is your ltsp server correctly configured for sure?
| |
| 10:08 | <emence> markit: thats the million dollar question. I think it is
| |
| 10:08 | <markit> emence: if you are good with wireshark, you can look at what's looking for
| |
| 10:08 | <emence> im downloading the actual k2 linux live server for a USB boot and gonna try it out with that one
| |
| 10:09 | wireshark.. lemme tr that
| |
| 10:09 | <markit> usually is a tftp misconfiguration
| |
| 10:09 | so it's pointing to the wrong path
| |
| 10:10 | or NFS not configured (if you are in debian), or something like that (don't know about THAT precise error message)
| |
| 10:14 | btw the answer of my question seems, thanks to grep in /etc/, that is something that has to be set in chroot
| |
| 10:15 | since is checked there... or chroot inherites the environment variables of the "host"?
| |
| 10:15 | <emence> hmm

| 11:09 | <asmok> LTSP-Cluster admin page is empty. But there is this kind of line in Apahce2 logs.
| |
| 11:09 | [Sun Apr 11 18:56:10 2010] [error] [client 192.168.1.210] PHP Parse error: syntax error, unexpected '(', expecting T_STRING in /usr/share/ltsp-cluster-control/Admin/index.php on line 62

| 11:11 | I have been very careful when editing config file:

| 11:11 | http://www.mail-archive.com/edubuntu-devel@lists.ubuntu.com/msg02964.html
| |
| 11:19 | <johnny> asmok, what's between line 62 and 64 ?
| |
| 11:19 | err
| |
| 11:19 | 61 and 63

| 11:27 | <asmok> wait a minute
| |
| 11:29 | I think:
| |
| 11:29 | goTo('admin.php');
| |
| 11:29 | <johnny> print all 3 lines..
| |
| 11:30 | <asmok> }
| |
| 11:30 | goTo('admin.php');
| |
| 11:30 | die(getMessage('good_login'));
| |
| 11:31 | <johnny> ok.. 60..
| |
| 11:31 | unless it's a blank line
| |
| 11:31 | then 59
| |
| 11:31 | <markit> I've a 19" lcd monitor. I've Kubuntu 10.04 with ltsp. Thin clients set it to 800x600, instead of 1280x1024. Is it possible that ltsp xorg monitor detection is different than the "normal" kubuntu 10.04?
| |
| 11:31 | <asmok> I upload whole file for you, wait a minute
| |
| 11:31 | <johnny> asmok, paste it to a pastebin
| |
| 11:31 | codepad is a good choice for php
| |
| 11:32 | markit, it's probably related to the monitor
| |
| 11:32 | it shouldn't be different tho
| |
| 11:32 | markit, see if you can manually change it via the kde tools
| |
| 11:32 | if it sticks, then you can work around the problem
| |
| 11:33 | via passing some options @lts.conf
| |
| 11:33 | markit, did you try this monitor on a non ltsp client?
| |
| 11:33 | <asmok> here: http://codepad.org/qHK1CrmE
| |
| 11:34 | <johnny> it might be be related to ltsp at all, but your monitor being sucky and not telling x your edid info
| |
| 11:34 | not be*
| |
| 11:34 | <markit> johnny: the same monitor is connected to the server (vga) and works fine, and to the client (DVI) and is set to 800x600
| |
| 11:35 | (I'm just testing ltsp with a server and a client)
| |
| 11:35 | <johnny> those are 2 different variables
| |
| 11:35 | dvi vs vga
| |
| 11:35 | <markit> if I boot the client with it's own Kubuntu (but is 9.10) works fine too
| |
| 11:35 | <johnny> markit, ok.. that's valuable :)
| |
| 11:35 | <markit> lol
| |
| 11:35 | <johnny> some folks know how to work around that
| |
| 11:35 | i don't
| |
| 11:35 | <markit> johnny: I know you can pass the resolution parameter and stick with MAC address, but I'm really surprised
| |
| 11:35 | <johnny> it shouldn't be different in this case
| |
| 11:36 | <markit> and it makes me frigtened...
| |
| 11:36 | <johnny> it used to be
| |
| 11:36 | frightened?
| |
| 11:36 | that's a bit over the top huh
| |
| 11:36 | <markit> I mean, I can test monitors with a kubuntu live with a pc
| |
| 11:36 | <johnny> asmok, looks fine to me.. file a bug
| |
| 11:36 | <markit> but I'm not sure it will work fine once I will use that pc as a client
| |
| 11:36 | <johnny> well. that's the way it goes sometimes
| |
| 11:36 | <markit> should not, if xorg is the same
| |
| 11:37 | <johnny> except we do magic
| |
| 11:37 | we have to work around override some things in the startup scripts
| |
| 11:37 | and sometimes things get clobbered
| |
| 11:37 | you don't have CONFIGURE_X in lts.conf or anything like that do you?
| |
| 11:38 | because that would definitely override it
| |
| 11:38 | <asmok> johnny, I'll do that, thank you and bye
| |
| 11:38 | asmok has left #ltsp | |
| 11:41 | <markit> funny, the new atom based client has problems, while the old athlon 1000 works like a charm with that monitor
| |
| 11:41 | johnny: I've barebone installation, don't think there is a lts.conf at all! :)
| |
| 11:44 | btw, I've a school with 3 classes (one per year) with 16-20 students
| |
| 11:44 | I want to create users like "student_01... student_99"
| |
| 11:44 | with a random password
| |
| 11:45 | and give the list to the teachers
| |
| 11:45 | is a good aproach?
| |
| 11:50 | Faithful has joined #ltsp | |
| 11:59 | <markit> mm moving and updating windows is not that fast, sigh
| |
| 11:59 | <johnny> sure..
| |
| 11:59 | markit, turn on LDM_DIRECTX
| |
| 11:59 | <markit> johnny: any script that can do it automatically? should be a common ltsp problem
| |
| 11:59 | <johnny> in lts.conf
| |
| 12:00 | others can answer that
| |
| 12:00 | i only have 3 users
| |
| 12:00 | try back when more people are here
| |
| 12:00 | LDM_DIRECTX doesn't encrypt the X session
| |
| 12:00 | so it should be faster
| |
| 12:00 | <markit> mmm I think is slow because of the old video board
| |
| 12:00 | the switch is gbit, the client nic 100mbs
| |
| 12:01 | <johnny> LDM_DIRECTX will make things much faster in any case
| |
| 12:01 | <markit> athlon 100 should be enough
| |
| 12:01 | correct
| |
| 12:01 | and encryption is useless in this case
| |
| 12:01 | (the switch and lan is dedicated to clients)
| |
| 12:01 | in any case, good suggestion, thanks
| |
| 12:01 | let me try :)
| |
| 12:09 | rebooting the client...

| 12:14 | <markit> mm seems faster but not much, maybe I'd better check the traffic to be sure is working
| |
| 12:15 | rjune has quit IRC | |
| 12:15 | <markit> ok, seems a ton of traffic outside port 22, good
| |
| 12:20 | alkisg has joined #ltsp | |
| 12:23 | <markit> johnny: are you an expert in updating chroot? I've a dubt about the unmount sequence
| |
| 12:23 | before or after ltsp-update-kernels ?
| |
| 12:23 | (or if anyone else knowns the answer)
| |
| 12:24 | upstream says before, https://help.ubuntu.com/community/UbuntuLTSP/UpdatingChroot after
| |
| 12:25 | ubuntu should try to use the same sequence, if is not a issue, just for uniformity
| |
| 12:25 | newbie users like me become very confused
| |
| 12:26 | <alkisg> markit: that ubuntu wiki page is wrong, if you have the time do correct it
| |
| 12:26 | export VAR=VALUE followed by sudo chroot => the VAR is not set inside the chroot
| |
| 12:29 | ...and the script at the bottom of the page is also wrong
| |
| 12:32 | pmatulis: ^^^ - for the script, an easy way to do it is: `sudo LTSP_HANDLE_DAEMONS=false chroot /opt/ltsp/i386 apt-get dist-upgrade`
| |
| 12:34 | <johnny> alkisg, perhaps we need some wrapper script for this
| |
| 12:35 | btw.. this is why i think packagekit is important :)
| |
| 12:35 | * alkisg has one in sch-scripts... | |
| 12:35 | <alkisg> "ltsp-enter-chroot"
| |
| 12:36 | <johnny> but you shouldn't need to enter the chroot just to one one command
| |
| 12:40 | <alkisg> It's in a GUI menu, so it doesn't make a difference if it is for one or more commands...
| |
| 12:40 | <markit> alkisg: ehm, I would love to fix the wiki, but since I'm not an expert, I fear do more harm than good
| |
| 12:40 | Barbosa_ has quit IRC | |
| 12:41 | <alkisg> markit: I meant to put there what's in the upstream docs...
| |
| 12:42 | <markit> ok
| |
| 12:42 | <alkisg> Anyway /me goes back to trying to learn about python packaging :(
| |
| 12:42 | <markit> alkisg: why you say variable is not set inside the chroot?
| |
| 12:43 | mmm I'll try later
| |
| 12:43 | <alkisg> markit: `sudo` does not inherit the environment
| |
| 12:43 | VAR=value sudo env | grep VAR ==> nothing
| |
| 12:44 | But, sudo VAR=value env | grep VAR ==> the VAR is there
| |
| 12:44 | <markit> I see, thanks
