<johnny>
kc8pxy_, but they are really gonna need a pulse driver anyways.. since pulse is going to be default on almost all linux distros
00:00
desktop ones anyways..
00:02
<stgraber>
IIRC wine has a pulse driver
00:02
hmm, it appears not to be there ... I remember reading about one somewhere ...
00:03
anyway, you can probably just use wine with the alsa output (not the OSS one), it should then use the pulse alsa device
00:09
<johnny>
or.. the esd driver.. :)
00:09
i'd never seen the pulse driver, thus i mentioned it..

hi nubae
09:06
i need a little more help with the fat client setup
09:07
i boot my client, as far as i can see the client mounts the nfs home from the server but the gdm doesn't respond to the keyboard
09:07
the client isn't pingable neither
09:23petre has joined #ltsp
09:28
<Nubae>
hi tostado
09:29
gdm doesnt respond to the keyboard? u mean u can't type?
09:31
ok, lets debug this a bit.... first, cat /opt/ltsp/fati386/etc/network/interfaces
09:33
<tostado>
auto lo
09:34
iface lo inet loopback
09:34
thats all
09:36
and i don't get a terminal on the client, no ssh so its VERY hard to debug
09:39
<Nubae>
hah
09:39
it seems to have killed the networking...
09:39
<tostado>
yes
09:39
<Nubae>
edit that file and copy your settings from the server to there
09:39
should just be auto eth0 inet dhcp
09:39
<tostado>
at the end of rcS.d it's still alive
09:40
ok
09:40
<Nubae>
yeah looks like ltsp is overwriting networking... it doesnt in intrepid... but for now a fix is just to add the networking details there
09:40
<tostado>
and run sp-update-image again i suppose
09:40
<Nubae>
so this line: auto eth0 inet dhcp
09:41
wait... let me double check that
09:41
<tostado>
auto lo
09:41
iface lo inet loopback
09:41
auto eth0
09:41
iface eth0 inet dhcp
09:41
<Nubae>
right :-)
09:42
then rebuild image yeah
09:42
<tostado>
puh, this damn mksquashfs...
09:42
<Nubae>
yeah... u can turn nbd off and use nfs
09:42
<tostado>
even on my murder fast dualcore server it takes minutes
09:42
<Nubae>
then u dont have to rebuild, but hopefully this is the last time
09:42
<tostado>
ok ;)
09:43
so you suppose to use nfs rather than nbd for /home ?
09:53
ahhh... now it hangs after Loading Hardware drivers...
09:55
is it ok that it boots nbi.img ?
09:57
<johnny>
hmm..
09:57
bzr gedit integration... interesting..
10:09
<Nubae>
if it hangs, its probably not finding the nfs server
10:09
yeah /home is mounted over nfs
10:10
<tostado>
but before it went further...
10:13
so what can i do ?
10:13
<johnny>
burn all computers
10:13
<tostado>
;)
10:14* johnny has yet to use Nubae's new fun stuff yet
10:14* johnny is happy with what Nubae does tho
10:14
<johnny>
ok.. so .. bzr.eclass finally made it into portage, this makes me happy :)
10:15
now.. i just need to get some shmuck to fix up genkernel :(
10:15
that's the most annoying thing to try to deal with atm
10:15
<Nubae>
well... wehre is it getting stuck?
10:18
tostado: check to see if it stops at nfs or portmap
10:24
<tostado>
ok
10:25
the last service is Starting NFS common utilities...
10:25
(i now have the network/interfaces at its original state)
10:25
<Nubae>
it must be with the changes u made though... it wont work without that
10:26
edit /etc/nfs.sh or whatever its called in the chroot
10:26
<tostado>
hmm... but with the changes i made it hangs very early
10:27
hmmm ok
10:27
<Nubae>
and make sure /etc/init.d/portmap restart and /etc/init.d/nfs-kernel-server restart are in there
10:27
that should take care of the nfs part....
10:29
<tostado>
but /etc/init.d/nfs-kernel-server restart on the client ?
10:31
<Nubae>
oh shit sorry
10:31
nfs-common restart

u switched bluetooth off right?
10:34
in /etc/default/bluetooth?
10:43
<johnny>
why should bluetooth be on ?
10:44
shouldn't it only turn on.. if you have a bluetooth device plugged in?
10:44vagrantc has joined #ltsp
10:45
<Nubae>
no stupid thin turns on by default
10:45
in hardy
10:45
in intrepid its fine
10:45
all these are hardy problems
10:47
<tostado>
so if i'm stuck here with hardy i could change to intrepid...
10:48
<Nubae>
it would make it work out of the box
10:48
<tostado>
ok. i think i try this.
10:48
<Nubae>
i intend to fix the hardy script, but I need more hours in the day
10:49
<tostado>
nevermind. i do an intrepid install
10:49
do you think dist-upgrade will do also or should i install a fresh intrepid ?
10:49K_O-Gnom has quit IRC

12:33johnny is now known as Guest31724
12:33
<tostado>
first boot look good, can login, but the apps still run on the server
12:36
<Nubae>
tostado: check: http://www.nubae.com and click on the fatclient link
12:36
it describes there how to set up dhcpd.conf
12:38Guest31724 is now known as johnny
12:38
<ltsppbot>
"tost." pasted "dhcp.conf" (28 lines) at http://pastebot.ltsp.org/75
12:39
<tostado>
the client boots /ltsp/amd64fat/nbi.img
12:41
wait: i tried the console
12:41
and there i am on the client :)
12:42
but the gnome session runs on the server, and with that also apps that i start from gnome-terminal
12:45
<Nubae>
take out the second part of your dhcpd.conf file, u already defne the subnet above
12:46
and if you have a host named pncl1, it must also be in /etc/hosts
12:47
¬¬¬
12:48
Im a little confused
12:48
either everything runs on the server, or everything on the client, its not possible that it runs some on one side and some on the other
12:53
<johnny>
in hardy that is..
12:58
<Nubae>
without local apps that is
13:07
<tostado>
the second part of the dhcpd.conf is another different subnet
13:08
192.168.217.32 and 192.168.217.0
13:08
pncl1 is in /etc/hosts

<tostado>
hej i have to go
13:09
i'm fine at the moment, i dont need gnome, i can do startx via ssh and that runs locally
13:10
<Nubae>
ok, well it should be loading up gdm on the client just fine
13:10
<tostado>
but its strange that via gdm everything graphically runs on the server, three times tested.
13:10
<Nubae>
that is very odd....
13:10
<tostado>
so i will be back on tuesday or so.
13:10
thanks a lot !!!
13:10

<toddobryan>
I'm on Ubuntu 8.04 with LTSP 5. I'd like to install something on the clients, but have to build it from source. Can I do something like ./configure --prefix=/opt/ltsp/i386/usr/local or is that just not the way to do it?
16:04
<Ryan52>
toddobryan: that should work...but why not just "chroot /opt/ltsp/i386" and do the build in there?
16:09johnny has left #ltsp
16:09
<toddobryan>
Ryan52: I don't want to install all the necessary dev packages in the thin client filesystem. Am I just being overly conservative?
16:10
<Ryan52>
oh, that makes sense.
16:17
<jammcq>
--prefix prolly won't work. at run time, the app may be expecting to find things relative to whatever you specify for --prefix
16:17
but at run time, it won't be the same
16:23
<vagrantc>
toddobryan: build a debian package out of it, install it into a repository, and then "apt-get install" it in the chroot.
16:25bobby_C has joined #ltsp
16:27
<stgraber>
jammcq: hey, btw I wonderd, do we (Francis and I) need to do anything for LTSP BTS (like booking the room ?) or is there enough room not to care about that ? :)
16:32
<jammcq>
stgraber: no need to book the room
16:32
we've got the whole motel
16:32
A few days in advance, I'll tell them roughly how many rooms we need and they'll be ready for us
16:32
<stgraber>
ok, cool
16:38
<vagrantc>
stgraber, sbalneav: was the cdpinger segfault bug reported on launchpad?
16:38
i need to make a case for getting it into debian lenny
16:39
<stgraber>
let me check the changelog, if it's a bug in LP, I added it to the changelog (so it gets automatically closed)
16:39
<vagrantc>
it's not in the changelog
16:40
<stgraber>
so I don't think we have a bug for it, let me check
16:43bobby_C has quit IRC
16:44
<stgraber>
vagrantc: no bugs on LP, I checked both LTSP and ubuntu
16:44
<toddobryan>
vagrantc: I'd love a Debian package. But it's iTALC 1.0.9, and the latest I can find is 1.0.7.
16:45
<vagrantc>
toddobryan: probably not hard to take the packaging from 1.0.7 and update it to 1.0.9, unless they've made major changes.
16:45
<stgraber>
vagrantc: or just backport my package from Ubuntu, it includes all the LTSP magic
16:45alekibango has quit IRC

<vagrantc>
toddobryan: ^^ what stgraber says
16:45
<toddobryan>
stgraber: Where are you sticking ICA?
16:46
<stgraber>
toddobryan: I have ica on the thin client and italc on the server
16:46
<toddobryan>
I'd like to have it run locally on the clients, because I have two servers.
16:46
Cool. I've been trying to figure out how to run the master on my desktop machine so I don't have to bother the servers at all.

16:47
oops, wrong link :)
16:47
http://ppa.launchpad.net/edubuntu-italc-devel/ubuntu/pool/main/i/italc/
16:47
that's the one I wanted ^:)
16:48
so you can take 0ubuntu3 and rebuild it for Debian, I don't think I have any Ubuntu-specific hack in there
16:49Hyperbyte has quit IRC
16:49* vagrantc thought toddobryan was using ubuntu
16:50
<stgraber>
hmm, right I didn't look at the backlog
16:50
toddobryan: so you can just add my PPA to the chroot and install it from there
16:50
<toddobryan>
I'm actually doing it on Ubuntu 8.04.

stgraber: Do I need to do anything to get ica to run on thin client boot, or does the package handle that?
17:11
<stgraber>
toddobryan: you need START_ITALC=True in lts.conf
17:13
<toddobryan>
Thanks. Sorry if this seems disjointed. I'm running back and forth to the server room.

Stupid question...where's the login screen graphic saved?
17:25Q-FUNK has quit IRC

vagrantc_: did you figure out the cdpinger seg faulting?
19:40
<vagrantc_>
Ryan52: figure it out?
19:41
<stgraber>
Ryan52: it should be fixed (at least a fix has been uploaded and is now in upstream and Ubuntu)
19:41
<Ryan52>
oh
19:41
<stgraber>
Ryan52: what vagrantc_ was looking for is a bug in LP he can refer to in his changelog
19:42
<vagrantc_>
well, more to refer to the debian-release team... as i don't have any documentation suggesting that it's acutally necessary ... although "fix segfault" looks like A Good Thing.
19:43
i also added a change to the 0.5.5-1 package so that ubuntu would be able to pull it, and it'd be annoying to have to revert that just to get it into lenny.
19:43
so i could backport the patch to 0.5.3 (i think it will just apply without changes)

That's right.
23:24
<stgraber>
kwak: you can run 25 clients on 3GB, I'm doing it at the moment, our plan is to put 50 clients on 4GB (with some more services than just LTSP on the server)
23:24
<kwak>
stgraber, what's the CPU
23:24
<stgraber>
I currently have 33 clients on 3GB
23:24
CoreQuad
23:24
2.5Ghz
23:25
<kwak>
maybe that makes the difference, i'm using Xeon Dual 2.8
23:25
what distro are you using?
23:25
<stgraber>
Ubuntu
23:26
<kwak>
stgrabber, edubuntu?
23:26
<stgraber>
yeah, iTalc showing 37 computers at the same time !!! :)
23:26
we are using standard Ubuntu + the edubuntu meta packages
23:26
edubuntu is now an addon on top of Ubuntu
23:26
<kwak>
ic, i tried that couple of months ago, but had speed issues.
23:26
<stgraber>
and LTSP is now an installation option of the Ubuntu alternate CD
23:27
<kwak>
somebody told me to change a setting.
23:27
but didn't try yet
23:36
i noticed that ram requirements for server have gone up. before the required RAM is 512MB + 50mb for each client
23:47
<stgraber>
for the first one who pretends that iTalc doesn't scale: http://www.stgraber.org/download/italc-ltsp.png
