I used ltsp-build-client to make an i386 debian wheezy client, used ltsp-standalone-server for the server, the booring works fine but when I get to the X login i get server is not responding. I tried ltsp-update-image and update-ssh , but without succes. any ideas?

yids, hi
05:42
!update-sshkeys
05:42
<ltsp>
I do not know about 'update-sshkeys', but I do know about these similar topics: 'ltsp-update-sshkeys'
05:42
<Hyperbyte>
!ltsp-update-sshkeys
05:42
<ltsp>
ltsp-update-sshkeys: If you changed your server IP, you need to run ltsp-update-sshkeys, and if you're using NBD (Ubuntu) you also need ltsp-update-image afterwards
05:42
<Hyperbyte>
Make sure you run that -before- you run ltsp-update-image... or rather, make sure you run ltsp-update-image afterwards.
05:43
If it's still not working, get a root shell on the thin client
05:43
!screen_02
05:43
<ltsp>
screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
05:43
<Hyperbyte>
And from there try to log in, using ssh yids@server
05:44
Only replace 'yids' with the username you need, leave '@server' as it is. Because 'server' is the server LDM is trying to connect to.
05:44adrianorg_ has left IRC (adrianorg_!~adrianorg@187.115.105.197, Ping timeout: 240 seconds)
05:44
<Hyperbyte>
See if you can log in manually, using plain ol' SSH.
05:44
If that works, then LDM works as well.
05:45
If it gives a warning about adding a host key for a server to known hosts, then you have a problem with host keys.
05:46
If it doesn't work, paste error message from client on pastebin. Also check /var/log/auth.log on the server and paste those error messages on pastebin as well.

hi, I've configured FAT RAM THRESHOLD, but how can I check if a client is using thin or fat?
10:55ogra_ has left IRC (ogra_!~ogra_@p5098ed03.dip0.t-ipconnect.de, Ping timeout: 276 seconds)
10:59
<der_baer>
Joanet: the default client is thin so as fare as you use the default you shut have a thin client (you can also check with ps aux on your thin client if any userland software runs on it, if yes it is a fat client)
11:02
<Hyperbyte>
Bash hackers wanted. How do I get all arguments to script from $2 and onwards?
11:02
So something like "$2 $3 $4 $5 $6 ... etc"
11:13
<highvoltage>
$@
11:13
<Hyperbyte>
That includes $1 though
11:14
I went with some really geeky awk for-loop.... found it somewhere on stackoverflow. :)
11:14
<highvoltage>
heh
11:15
<Joanet>
der_baer: I've modified now lts.conf file to set LTSP_FATCLIENT to True, but when I try to log on a client it gets stuck on logon screen. I'm using Edubuntu 12.04 (and all about fat clients described at ubuntuLTSP help was written). Only ltf.conf file was modified
11:17
<highvoltage>
Hyperbyte: would $1 always be different than the rest of the arguements? otherwise something small could be something like echo $@ | sed -s "s/$1 //g"
11:18
<Hyperbyte>
highvoltage, that's a bit tricky though. It's both external input. :)
11:19
The awk command I'm using now loops through all arguments from the 2nd on, onwards and prints them... seems to work ok, although it's black magic code

11:39
<der_baer>
Joanet: mm build a new chroot with "ltsp-build-client --fat-client-desktop" that shut work (thats how i doing it) maybe this FATCLIENT option in lts.conf is buggy

<Emmanuel>
Hi, question here. I'm using a debian 7 machine as ltsp server.
15:50
The clients are set up as fat clients and use xfce4
15:51
I assigned the IPs statically on the dhcp.conf file on the server.
15:51
But I can't get auto login to work
15:52der_baer has left IRC (der_baer!~user@pd95cdee4.dip0.t-ipconnect.de)
15:53
<Emmanuel>
All the articles I've seen point to editing /var/lib/tftpboot/ltsp/i386/lts.conf to acomplish it
15:53awilliams has joined IRC (awilliams!~awilliams@unaffiliated/mistik1)
15:53
<Emmanuel>
and I did, but, well, with no success
15:53
any tips? am I missing something?
16:01
<workingcats>
Emmanuel, WFM with this in lts.conf: [00:1e:0b:25:f1:68]
16:01
LDM_USERNAME = user
16:01
LDM_PASSWORD = pass
16:02
the number in the square brackets is the MAC addr
16:02
<Emmanuel>
Yup, that's what I did
16:02
I also added the variable
16:02
LDM_AUTOLOGIN = True
16:02
<workingcats>
oh yeah that too sorry
16:03
pastebin your whole lts.conf
16:04
<Emmanuel>
well, the file is not that big, actually, it just has that statement
16:04
<workingcats>
so you have a default section and a MAC-specific section?
16:04
or just one of the two?
16:05
<Emmanuel>
since the default section didn't have anything, I just deleted it
16:05
and added the LDM_AUTOLOGIN = True value on the mac specific part
16:06
I did tried it with the autologin variable on the default part. didn't work either
16:06
<workingcats>
hm
16:06
but manual login works?
16:07
<Emmanuel>
that works just fine
16:07
I was starting to wonder if it had to do with xfce or something
16:08
<workingcats>
well this is my whole conf http://pastebin.com/PWxgxTfr
16:08
with zentyal3/ubuntu1204
16:08
maybe a default section is mandatory
16:09
<Emmanuel>
it didn't work when I had it either, but I'll re add it, just to be on the safe side
16:12
I see
16:12
well, I'll give it a shot
16:13
I added a few of your lines to mine, changing where needed
16:13
and, I'm rebooting, just to be sure
16:15
<workingcats>
dont think its necessary but it certainly doesnt hurt
16:18
<Emmanuel>
I know it isn't, but I'm trying to be as cautious as possible
16:20
aaand, it didn't work

<workingcats>
hm i'm afraid i'm all out then :/
16:31
actually you could check the logs
16:31
on the server if it gets anything
16:31
and on the client after logging in as local root
16:31
<Emmanuel>
yeah, that should give me some hints
16:32
I'm not on my top game today, should have checked those from the start

<imox>
it is possible to rebuild the client image if I change the /var/lib/tftpboot/ltsp/i386/lts.conf ?
20:45
<Hyperbyte>
imox, it's possible to rebuild the client image at any time.
20:45
But it's only necessary if you change something inside /opt/ltsp/
20:45
<imox>
^^ im mean necessary ^^
20:45
<Hyperbyte>
;-)
20:45
<imox>
thanks
20:46
<Hyperbyte>
Things in tftpboot are loaded on client startup via tftp (hence the tftpboot name)... they're not part of the image
20:46
So no image rebuild is needed.
20:47
<imox>
ok thx
