Hello, new person here. Have used K12ltsp at my former job for years, running it on FC and Centos. I have just recently set a new system up at my new job and it is Ubuntu 9.04 with the ltsp install. I have two problems I'm hoping to get help with..first, none of the thin clients will touch the internet if root is NOT physically logged into the server box. When root is logged into the server all is well, when I log it out, it seems no DNS
07:59
is available to the thin clients...make any sense to anyone?
08:01
<laga>
there is no root user in ubuntu
08:01
how do you log in?
08:01
<johntl>
I allowed a root login locally
08:02
by following directions found on the net

Does anyone have some opinion on http://drbl.sourceforge.net? I'd like to use it as a fat client solution and I'm looking for whatever negative stuff may be there that I'm not seeing...
08:33
<moldy>
no experience with that, sorry. but while we're at it: can i use ltsp as a fat client solution? how much work is it?
08:34
<NeonLicht>
It's supposed to be possible, moldy.
08:35
<moldy>
hmm :)
08:35
that can mean alot of things ;)
08:36
<NeonLicht>
I mean I think I've read that it's possible, but I have no idea how to do it or where I read about it.
08:36
<moldy>
ok, thank you
08:37
<NeonLicht>
Now that I remember, vagrantc told me I could do it using my thin clients when he was here and saw them.
08:37
They are powerful enough.
08:38
<moldy>
my thin clients can run ubuntu fine as standalone computers, but i wonder how much work it is to set them up as diskless fat clients
08:38nubae has quit IRC
08:41
<alkisg>
moldy: the typical ltsp-based solution for fat clients is this: http://nubae.com/ltsp-linux-terminal-server-project-netbooted-fat-client-for-ubuntu-hardy-and-intrepid
08:42
Also newer ltsp versions support localapps
08:42
But I was looking at DRBL because if it does what I think it does, then there's no chroot involved, which would mean no administration overhead for the teachers

<moldy>
alkisg: looks interesting, thank you
08:47
alkisg: so the rationale is that you just create a chroot with ubuntu-desktop and so on installed?
08:47
<alkisg>
In nubae's script? Yes. In DRBL? no, the "server" os is used as it is.
08:47
<moldy>
alkisg: yeah, i mean the script
08:47
sounds interesting

12:37
<nubae>
alkisg, did u check out drbl?
12:37
<alkisg>
nubae, yes
12:37
It does what I want, but in very broken ways
12:37
And it's a pain to setup
12:38
Instead of doing bind-mounts, it creates /etc in a tmpfs from a tarred version of the "server" /etc
12:38
<nubae>
yeah it is
12:38
its why I abandoned it
12:39
still, might have some interesting features to incorporate
12:39
<alkisg>
I think by doing what ltsp-client-setup does, I can the things I want with 1-2 simple scripts
12:39
No I don't think so. I think ltsp-client-setup is a better source for info.
12:40
<nubae>
ok but that would be similar to my fat client script, maybe u wanna hack at that
12:40
<alkisg>
The only thing I "took" from it is the NIS idea:
12:40
instead of sharing /etc/passwd over a really insecure nfs share, they are using nis
12:40
But I don't care about security so I don't know if that would be better.
12:40
<nubae>
well I use ssh to transfer that
12:41
although its very hackish
12:41
but it works
12:41
<alkisg>
LTSP is no secure either. Any client get boot from the server and get the ssh keys.
12:41johntl has joined #ltsp
12:41
<nubae>
yeah
12:41
<alkisg>
What I'm thinking would be a lot different from your fat client script. It wouldn't involve ltsp at all, for one.
12:42
<nubae>
ok, well once u have it, I'd love to take a look
12:42
<alkisg>
I'd just put ltsp-client-setup in the server /etc/init.d, and share / with nfs
12:42
OK. I think the end result will worth the trouble, fat clients with no administration at all.

user_: patience!
16:47
<user_>
ok...I am sorry..
16:47
<Ryan52>
I think you need to do LDM_AUTOLOGIN=true
16:47
(or something like that)
16:48
check the docs, there's some setting you need to turn on to enable autologin.
16:51
<user_>
ok. thanks..I will search

17:29
now the auto login is ok
17:29
thanks
17:29
<Ryan52>
okay, great, np.
17:30
<user_>
but have another problem with nbd..some clients show me something like SQUAHFS ERROR while then are booting
17:30

stgraber: just curious what it's doing
20:04
<stgraber>
vagrantc: we need that for a few customers who have password change dialog that connects directly to their directory before the SSH session is open
20:05
we can't run that afterwards because SSH login would be rejected
20:06
we might also use it for LTSP-Cluster as it'd allow us to change the SSH command line (with some more changes to ldm) and for example redirect the user to a different server depending on a few scripts
20:06ogra has quit IRC

20:06
<stgraber>
or make sure the server that was the least loaded when ldm was started is still the one you should use
20:07
that last use case is quite interesting because usually all our thin clients boot at 8am and are only used at around 9am. But as the loadbalancing request is made when ldm starts and not at login, you may be directed to an extremely loaded server.
