hi there. could anyone tell me if it is a problem to create/serve ubuntu 12.04 client images on/from a 10.04 server?
11:51
we have a working ltsp-cluster setup here with 10.04. now there are some new thin clients where the gpu seems to require 12.04 to be supported. i built an 12.04 client image but end up in initramfs busybox. :(

sral: but i failed to get a 1204 client to work so far...
12:00
sral: same problem here. initramfs busybox, but i also have this problem on a 1204 server
12:16
<avijit>
how i will block usb-storage divice in ubuntu ltsp-cluster ? please help me
12:17
<sral>
tarzeau: :(
12:18
does anyone knows a way to troubleshoot this?
12:18
<avijit>
I had try to block usb-storare in blacklist.conf file but it's not working in ltsp image , please help me
12:23
does anyone knows
12:29
<sral>
tarzeau: i guess our problem is that nbd is run different in 12.04. not through inetd anymore an on standard port.
12:32
<tarzeau>
sral: aha...
12:32
sral: if you find a solution, you tell me? sengun@phys.ethz.ch
12:32
sral: i had configured the boot parameter nbd block port and set it up in inetd, but without success
12:33
yeah something changed, and it's not documented (not easily to find)
12:45
<sral>
this was the hint i found: http://sourceforge.net/mailarchive/forum.php?thread_name=CAOc%3DAV_bgpzOtyxWmbiQNQrxS9VukFx9_mXkDO6yZShLdgDWaA%40mail.gmail.com&forum_name=ltsp-discuss
12:46
i guess my next step is upgrading the root-server. :/

hi all! :) Happy to join this channel... I've some questions about ltsp! :P
14:13
Here's my situation: I've just finished to setup my ltsp server, and I've booted my first zero client! I use a xfreerdp screen to connect the client to a windows multipoint server! Unfortunately I've some problemas with the audio redirection on the client! I can see that the audio device are working on the client, but I can'l listen anything! Why? Thanks in advance for any help/suggestions!

sbalneav: We are now using lightdm instead of ldm on ltsp thin clients, but with pam_krb5 + libnss-extrausers over here.
14:58
https://github.com/opinsys/ltsp-lightdm
15:00
sbalneav: debian packaging for it is here: https://github.com/opinsys/opinsys-debs/tree/master/packages/ltsp-lightdm
15:01
Basically we authenticate the user with pam_krb5, call a script with pam_exec to update a file for libnss-extrausers and then login the user. libpam-sshauth should also work, but as we also need the kerberos ticket on the client, we skipped that part.
15:02
It's not in production yet, but will be in two weeks

vmlintu: Good to hear it's working
15:44
<vmlintu>
sbalneav: Are you planning to use libnss-sshsock or libnss-extrausers?
15:45
<sbalneav>
Not sure at this point, but I do want to use libpam-sshsock.
15:46
Does everything work with libnss-extrausers?
15:46
i.e. need anything from me?
15:47
<vmlintu>
With libnss-extrausers everything seems to work. We only fetch getent passwd and group info for the user logging in as some of the installations have over >5000 users..
15:48
The getent info is fetched directly from LDAP using gssapi sasl authentication
15:54
<CiscoTHS>
Another detail: my ubuntu ltsp server is a virtual machine on a vmware esxi platform, on the server hardware i haven't an audio device. Can my problem born from a missing audio device?

knipwim: I am not sure, but I don't think so.
18:11
<knipwim>
i was afraid of that
18:11
<Phantomas>
knipwim: but maybe you can using series
18:11
seems you can translate multiple series
18:11
<knipwim>
then ldm-trunk should be in a different series
18:11
<Phantomas>
yes..
18:12
<knipwim>
but, i guess ldm is not that important to automate
18:12
since the plan is to replace it with lightdm
18:15
<Phantomas>
knipwim: Could you explain me what are you thinking to do? You can have a series for each branch you want to translate.

Phantomas: translations for ltsp-trunk and ldm-trunk via launchpad
18:25
check, i see
18:26
i can add a branch to a separate series

<Phantomas1>
knipwim: In this case, maybe the correct way would be to have a separate project for ldm and another one for ltsp, but since you plan to drop ldm it wouldn't be necessary
19:01Phantomas1 is now known as Phantomas
19:05
<Phantomas>
You could use series to achieve the same thing, but I think it doesn't make much sense since we are talking about different sub-projects, not different series.

<alkisg1>
sbalneav: i'm done with all the "reordering the cleanup phase" bits, but I'm still having a problem with the ssh socket being closed, even if I remove the endsession() call
19:24
...the actual problem of course is the sshfs mount, not the socket itself, but when the socket is closed, the sshfs mount is closed too
19:25
Could that be because the plugin is a child process of ldm, so when ldm terminates, the plugin terminates too?
19:25
(or is it the same process? not sure...)
19:25
Any thoughts on making the socket survive after ldm closes?
