<sweetpi>
can anyone tell me where the script that sets certain conf files as tmpfs is located?
00:25alkisg has joined #ltsp
00:25
<vagrantc>
sweetpi: which distro?
00:26
and version and such
00:26
<sweetpi>
debian squeeze
00:27
ltsp 5.2.2
00:27
<vagrantc>
it's called ltsp-bindmounts
00:27
it's in the chroot ... either usr/bin or usr/sbin, i think ...
00:27
you can override the defaults with lts.conf variables
00:27
oh, it might be in usr/share/ltsp
00:28
<sweetpi>
there it is, thanks
00:28
<vagrantc>
in usr/share/ltsp ?
00:29
<sweetpi>
hmm i can override.. nice, that in the docs?
00:29
yes
00:29
<vagrantc>
i don't think it's in the docs very well ... it's a pretty new thing
00:29* vagrantc isn't always the best at keeping up with docs
00:30
<sweetpi>
ok, how would i override copy_dirs or bindfiles?
00:30
rather append actually
00:30
<vagrantc>
append is something i've really been meaning to add ...
00:31
in lts.conf, LTSP_COPY_DIRS="/root /home ... /your/extra/dirs"
00:31
<sweetpi>
im trying to get wireless to come back up if it drops.. so im thinking adding the wpa conf might help
00:32
<vagrantc>
oh, adventurous
00:32
<sweetpi>
ok, so i need to set the defaults in there and then add mine?
00:32
<vagrantc>
yeah
00:33
<sweetpi>
thanks
00:33
oh.. i guess i need bindfiles.. not copydirs
00:33
LTSP_BINDFILES?
00:37
<vagrantc>
yup
00:38leio_ has quit IRC
00:38
<sweetpi>
hmm does that need to be in the initrd?
00:39
<vagrantc>
the way i implemented it... no :)
00:40
it's a little crazy, but it runs from the initramfs, but while the root filesystem is mounted, so it runs it chrooted to the root filesystem :)
00:40
<sweetpi>
nice
00:41
<vagrantc>
so i have access to more complicated tools than are available in the initramfs, but still happens before init even runs.
00:41
used to run from the init script, but that was hard to ensure that it ran early enough.
00:42
<sweetpi>
that worked good, now to figure out what i need to mount for the network to come back up... bleh
00:43alkisg has quit IRC
00:46
<sweetpi>
im glad you didnt put those in the initrd, im getting tired of copying new initrd's for one conf chage :)
00:46
s/chage/change/
00:57
<vagrantc>
indeed. i didn't like the idea either.
00:57
actually, i largely did it to avoid having to implement lts.conf handling in the initramfs :)
00:57
because clearly the configuration should be in lts.conf
00:58
<sweetpi>
you dont happen to know what would need to be in tempfs to be able to bring an interface up do you?
00:58
<vagrantc>
but i didn't like the idea of regenerating the initramfs if you don't have to...
00:58
sweetpi: using ifup/ifdown ?
00:59
<sweetpi>
i guess, right now im just testing yanking the card and plugging it back in
00:59
yeah, since ive added wireless support i seem to be updating the initrd every other change ha
01:02
oh.. pcmcia btw.. "yanking" the card might have sounded odd if you thought i was on a desktop :)

<zeitsofa>
hello :) - i was setting up a ltsp server and i thin client can boot. but i try to login as a user the error occured no answer from server - restart
05:11
<alkisg>
zeitsofa: is that ubuntu?
05:11
<zeitsofa>
alkisg: it is, yes.
05:11
<alkisg>
Try: sudo ltsp-update-sshkeys && sudo ltsp-update-image
05:13
<zeitsofa>
ah ok i didn#t create teh user on ltsp server. now i can login but there is a CLI - can i have a gui,too?
05:17
<alkisg>
Do you have a desktop environment installed on the server?
05:21
<zeitsofa>
i think i need a lts.conf for the clients. first i will create one
05:25
<ogra>
you dont need an lts.conf
05:25
<zeitsofa>
hmm ok but i dont have a running gui on the thin client
05:25
<ogra>
if your clients boot but you cant log in, the prob lies on the server side
05:26
you need a desktop environment installed
05:26
it doesnt need to be running, but it needs to be installed
05:26
<alkisg>
zeitsofa: did you use the ubuntu server cd to install the system?
05:34
<zeitsofa>
alkisg: yes i did
05:34
<alkisg>
zeitsofa: then you also need to run "apt-get install ubuntu-desktop"
05:35
zeitsofa: the proposed way to install LTSP is NOT with the server cd. It's with the alternate cd, which contains a GUI.
05:35
<zeitsofa>
alkisg: hrhr i did 2 minuts ago
05:35
alkisg: ok but i didn't have a gui the server is headless
05:36
<alkisg>
It doesn't matter. LTSP servers need a GUI to serve the clients.
05:42
<zeitsofa>
how did you mean "serve the clients"?
05:43
<alkisg>
When the clients boot, they need to get the OS and a GUI. They get it from the server. That is called the "client-server" model, where the server serves the clients.
05:50
<zeitsofa>
hmm - i have installed ubuntu-destop in the client image not on server, so the server can run headless.
05:50
<ogra>
the session after you log in on the client runs on the server, so you need all desktop session related apps installed on the server
05:50
that wont work
05:50
if your clients are beefy enough you could run them in fat client mode though
05:51
just installing ubuntu-desktop in the client env wont gain you anything
05:51
<zeitsofa>
hmmm ok.
05:54
so i have to install all programms for clients on the server?
06:04
<alkisg>
zeitsofa: yes, unless you follow this how to for fat clients: https://help.ubuntu.com/community/UbuntuLTSP/FatClients
06:06
<zeitsofa>
oh nice thx a lot
06:06
<alkisg>
zeitsofa: what are your client specs?
06:08
<zeitsofa>
atm there is a core i7 with 8GB RAM, but this is only a test client in future there a atom CPUs with 1,2GHz and 2GB RAM, floppy, cdrom, soundcard and usb ports
06:08
<alkisg>
OK, they're fine for fat clients.
06:09
<zeitsofa>
it is a test project - so i'd like to test the different ways and find a good solution for the end project.
06:10
but my favorite is a small thinclient with atom, because wie have a big 2x 3GHz xeon quadcore with up to 128 GB of ram.
06:12
<alkisg>
Atoms with 2GB RAM shouldn't work as thin clients...
06:12
They'll be much faster as fat clients
06:18
<zeitsofa>
hmm we only have atom board configurations here.
06:28
<alkisg>
So? they're fine.
06:32
<ogra>
you can surely use them as thin clients, its just a waste of processing power to do that :)

hmm no i have installed some packages on the server and run "ltsp-build-client && ltsp-update-sshkeys && ltsp-update-image" and boot the client. the client get ip and find bootimage - the ubuntu boot screen comes up but now i have a black screen :/
07:23
on tty[1-6] i have a login promt but not a graphical login comes up. any ideas?
07:29Faithful has quit IRC
07:38
<alkisg>
zeitsofa: "some packages" may not be enough. Did you install ubuntu-desktop?
07:38
<zeitsofa>
alkisg: yes i did
07:39
<alkisg>
What graphics card do the clients have?
07:39
<zeitsofa>
on this client there is a via s3
07:41
<alkisg>
Try with XSERVER=vesa in lts.conf
07:41
I.e. create a /var/lib/tftpboot/ltsp/i386/lts.conf file, with the following contents:
07:41
[Default]
07:41
XSERVER=vesa
07:42
(or try with a different client)
07:42
<zeitsofa>
ah ok. i have disable XSERVER=auto and gui comes up.
07:43
thx a lot :)
07:43Faithful has joined #ltsp
07:44
<zeitsofa>
alkisg: with vesa it works fine,too :)
07:44
<alkisg>
Don't use vesa if it works without it
07:44
<zeitsofa>
on first i try without xserver= line
07:48
alkisg: to use sun-jave6-sdk|jre|plugin i have to install on server right?
07:49
<alkisg>
Yes. Usually we just install the ubuntu-restricted-extras package, it has all the usual plugins (flash, java, codecs etc)
07:50
<zeitsofa>
really? on ubuntu10.04 sun's java is only in parnter repo available.
07:52
<alkisg>
Hmmm they changed it again, it only installs the icedtea6-plugin now... ok
07:53
<zeitsofa>
is this the real java from sun?
07:53
because we need the sun java package

hello - i'm testing dual-display under ltsp. my problem is i've got 2 monitors connected to thin client, and i'd like to use rdesktop on anotheer screen (like i used before: screen_5 & screen_6 were rdesktops to different machines, and screen7 - standard ldm) now i'd like to use 7 monitors under my linux enviroment (simply to viev my cctv cameras on one, and work on another)
09:20
main problem is that when i transfer to rdesktop screen - it's wide to 2 monitors and left-right is inverted, config is ok under my X, bun under rdesktop it looks like shit.

ok guys, I'm running ltsp on a fedora box, with dhcp on a windows server. All that seems to be working fine. The trouble is once the client boots, I attempt a login, and it comes back with "No response from server, restarting"
10:05
any ideas on where the trouble could be?

My fatclient setup is standard but I'm not able to apply a Sabayon profile. Sabayon is installed in the chroot. The profile is generated on another machine and them copied over. After a 'ltsp-update-image' I see the profile is copied to the users home directory but it is not effective whenteh user logs in.
