Hyperbyte: Hi, I installed the LTSP using http://wiki.debian.org/LTSP/Howto and got DHCP and LTSP GUI working but the user cant login, /var/log/daemon.log says http://ltsp.pastebin.com/bf50unrd
06:58
<Hyperbyte>
If you SSH to the terminal server, can you log in as the user you're trying to log in via LTSP?
06:59
<Trixboxer>
yup

See this:

<Trixboxer>
yeah.. Im trying to replace nbd with NFS but not successful yet
07:01
<Hyperbyte>
Okay, how far did you get?
07:02
<Trixboxer>
nfs server is running
07:02
/opt/ltsp is exported to world
07:03
in bug the guy has mentioned something about reducing the size of image... but how do I do that ?
07:06
<Hyperbyte>
To be perfectly honest, I haven't got a clue.
07:06
I use LTSP with Fedora, which uses NFS by default.

which is the best OS for LTSP.. Im deploying a set of 15 terminals and a single server

12:45
<sbalneav>
Debian, fedora, ubuntu and OpenSUSE all support LTSP
12:45
<Trixboxer>
Ubuntu or Fedora.. Confused
12:45
no CentOS ?
12:45
<sbalneav>
No one's ported it yet, as far as I know.
12:46
<Trixboxer>
Im working on ubuntu, but nbd is still causing problems :(
12:47
<sbalneav>
What problem? Is it the NBD proxy that's causing you a difficulty?
12:47
You can do that, or just use NFS
12:48
We're here at the LTSP hackfest, and I've got it on my todo to have a read through the nbd_proxy code.
12:49
<Trixboxer>
sbalneav: wow, nbd is giving me file size too big error
12:49
my i386.img file size is 560 mb
12:49
and i have no idea how to use NFS in LTSP
12:50
searching on google but not so lucky yet
12:51mgariepy has joined #ltsp
12:55
<sbalneav>
Trixboxer: https://help.ubuntu.com/community/UbuntuLTSP/LTSPWithoutNFS
12:55
There's a "reverting to NFS" section n there.
12:55
<Trixboxer>
without ?
12:55
is NBD better than NFS ?
12:57
<sbalneav>
Yes, NBD has some performance gains over nfs
12:57
where are you getting this error?
12:58
<Trixboxer>
daemon.log
12:58
/var/log/daemon.log
12:59
can I change NBD size limit ? I tried executing nbd-server command from shell but i think nbrootd is imp

can you paste the exact error message

13:01
<Trixboxer>
and BTW i followed instructions from http://wiki.debian.org/LTSP/Howto
13:03
<sbalneav>
There's no error thee about the file size being too large...
13:04
<Trixboxer>
The disconnect is issued because of that
13:05
I was able to see the GUI in client but when I logged in this message pops up
13:06
Do you have /usr/share/initramfs-tools/scripts/ltsp_nbd file ? according to patch mentioned in https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/485709 it should be there but I dont have it
13:07
<sbalneav>
check in /opt/ltsp/i38x/usr/share/init......
13:07
i386, sorry
13:07* vagrantc waves to sbalneav
13:07
<Trixboxer>
yeah got that
13:08
shall I apply the patch http://launchpadlibrarian.net/37462215/patch.diff to it ?
13:08
<sbalneav>
vagrantc: hey hey
13:08
Trixboxer: sure, try it and see if it helps.
13:08
just save a backupcopy so you can revert
13:08
<Trixboxer>
yuo
13:08
yup*
13:12robehend1 has joined #ltsp

<Trixboxer>
sbalneav: patch is not getting applied, its giving "Hunk #2 FAILED at 67.", shall I pastebin my ltsp_nbd ?
13:26
<sbalneav>
No.
13:27
<vagrantc>
i'd just grab the newest version of ltsp_nbd from bzr...
13:27
<sbalneav>
Just have a look at what the patch is changing, and manually fix up your ltsp_nbd
13:27
or, do as vagrantc suggested.
13:28
<vagrantc>
you can also dump it in /opt/ltsp/i386/etc/initramfs-tools/scripts instead of mangling the version shipped with the package ... the version in /etc will take precedence
13:30

<AndyGraybeal>
is it possible to have two X sessions on one machine? ctrl-alt-f7 & ctrl-alt-f8 ?
13:31
<vagrantc>
yes
13:32
<AndyGraybeal>
if i'm rnning music in f7 and switch to f8, will it stop playing the music in f7?
13:33
<vagrantc>
shouldn't
13:33
<AndyGraybeal>
interesting
13:33
is having two X sessions in the documentation?
13:34
okay i think i found some stuff from the mail list
13:35
<vagrantc>
SCREEN_07=ldm ; SCREEN_08=OTHERTHINGY
13:35dlezcano has quit IRC
13:35
<vagrantc>
you could even run SCREEN_07=ldm and SCREEN_08=ldm ... if for some reason you wanted two different users logged in from the same thin client...
13:36
<AndyGraybeal>
vagrantc: your amazing :)
13:37
<3's vagrantc
13:37
<vagrantc>
awww.
13:37
i like to help out when i can :)
13:37
makes it worth it
13:37
<AndyGraybeal>
what would OTHERTHINGY be other than ldm? gdm?
13:38
<vagrantc>
there's an rdesktop screen script for logging into windows servers (or linux servers running xrdp
13:38
ls /opt/ltsp/i386/usr/share/ltsp/screen.d/
13:38
<AndyGraybeal>
interstng
13:38
<vagrantc>
all sorts of crazy ideas in there.
13:38
<Ghidorah>
Isn't LTSP the best?
13:39
<Trixboxer>
vagrantc: new beginning, I have installed a new Ubuntu 10.04 server, now should I follow "https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall" ?
13:39
<AndyGraybeal>
Ghidorah: exactly :)
13:40
<vagrantc>
Trixboxer: i'm not sure what's the best documentation for ubuntu, but that doesn't sound like a bad starting point... hopefully. :)
13:40
<Ghidorah>
The docs on UbuntuLTSP are pretty nice
13:40
<abeehc>
Trixboxer: that's pretty well what i've used a few times in the last couple months
13:41
<alkisg>
Trixboxer: the disconnect is caused by a check made by the ldm scripts to see if there's a newer version of the image, and if it is, it prompts for a reboot. It's normal to see that disconnect (on /dev/nbd9)
13:42
If you're able to login and then X crashes and you logout, check for a possible compiz problem
13:42
!gnome-wm
13:42
<ltspbot>
alkisg: "gnome-wm" :: the default window manager in gnome is gnome-wm, which automatically chooses compiz if it thinks that the card supports it. Compiz is causing login problems to some clients. To disable it, see !disable_compiz. To restore it, see !restore_compiz
13:42
<robehend1>
I
13:42
I've been having compiz to, I just disabled it.
13:43
<Ghidorah>
robehend1: you have a few minutes? I'm trying to get this LTSP-Cluster going
13:43
and I'm not being too sucessful
13:43
<robehend1>
Ghidorah: Sure
13:44
<Trixboxer>
hmm ok... let me build the LTSP on ubuntu and will let u know guys.. doing it the 3rd time and counting...
13:44
<alkisg>
If you restarted with the server version, you'll need to install ubuntu-desktop as well (with tasksel install)
13:47
<Trixboxer>
alkisg: is that for me ?
13:47
<alkisg>
Yes, if you used the server CD
13:48
<Trixboxer>
I have installed ubuntu 10.04 Desktop
13:48
and now ltsp-server-standalone
13:48
<alkisg>
OK, I thought that you meant the server CD there: "new beginning, I have installed a new Ubuntu 10.04 server,"
13:48
Go ahead with the quick install page
13:48
<AndyGraybeal>
hmm i don't have lts.conf in /var/lib/tftpboot/ltsp/i386 .. is this normal if i haven't set any options in it?
13:49
<alkisg>
AndyGraybeal: yes, by default no lts.conf exists
13:49
<AndyGraybeal>
alkisg: cool, thank you
13:56
so i just edited /var/lib/tftboot/ltsp/i386/lts.conf and i added two lines: SCREEN_07=ldm & SCREEN_08=ldm .... i rebooted the thinclient, it only has x on F7, F8 is a blinking cursor in the top left corner. what did i do wrong?
13:56
i'm in ubuntu 10.04
13:59
<Trixboxer>
AndyGraybeal: Is your server 10.04 ?
13:59
<AndyGraybeal>
oh oh i didn't put a [Default]
14:00
do i need [Default]
14:00
?
14:00
Trixboxer: yes
14:00
<Trixboxer>
wow, I have good hopes then :)
14:02
<AndyGraybeal>
alkisg, vagrantc you each get licks! it works swimmingly.

AndyGraybeal, do u use NBD or NFS ?
14:12
<AndyGraybeal>
i'm not sure, i don't think i use either
14:14
<robehend1>
AndyGraybeal: If it's default LTSP-5, its NBD, i think

AndyGraybeal: It's the way your filesystem is mounted. Pretty nifty stuff.
14:20
<Trixboxer>
ok "ltsp-build-client --arch i386" done
14:21
should I install "nfs-kernel-server" or "nfs-server" ?
14:22
<abeehc>
they are one in the same as i recall
14:22
<Trixboxer>
hmm
14:22
ok will install "nfs-server"
14:22
<abeehc>
aptitude show nfs-server
14:23
<Trixboxer>
yeah same :P
14:24
is "/opt/ltsp *(ro,no_root_squash,async,no_subtree_check)" for /etc/exports correct ?
14:24
or /opt/ltsp/i386 ?
14:24
<alkisg>
Trixboxer: if you're having a compiz problem, nfs won't help... did you try booting your clients with the new setup?
14:25
<Trixboxer>
not yet... is /etc/exports not necessary ?
14:26dlezcano has joined #ltsp
14:28
<abeehc>
i don't think there's a good reason to setup nfs until you ahve the clients working maybe
14:28
<Trixboxer>
abeehc, one more lick from me
14:28
:D :D :D
14:28
u guys rocks
14:29
i think that was my mistake to export :(
14:29
its running flawlessly :)
14:29
<abeehc>
that's a strong word
14:29
i'm sure you'll find a challenge in there haha
14:29
<Trixboxer>
haha :)
14:29
I know that #ltsp is the place then
14:34
