Hi...I would like to ask : when I will change IP of machine where runs LTSP, should I regenerate image for clients?
08:40
<highvoltage>
I think running ltsp-update-keys is usually enough
08:40
(depending on your setup)

hi
12:09
I am trying ltsp on ubuntu 16.04 lts, I joined the server to an active directory domain, users can authenticate through the console (ssh) but not from the window manager
12:10
while local users can login on windows manager
12:12
the only error that I can see is this:
12:12
Apr 12 14:11:34 srterserlinux01 gnome-keyring-daemon[3928]: couldn't access control socket: /run/user/218004335/keyring/control: File o directory non esistente

12:18lucascastro has joined IRC (lucascastro!~lucas@186.227.186.18)
12:22
<alkisg>
SYS64738: are you talking about the ltsp server itself, or about the clients?
12:22
Configuring the ltsp server so that the window manager works (along with ssh) isn't related to ltsp
12:23
The ltsp clients authenticate to the server via ssh; so in turn they too use ldap, but indirectly
12:23
There's no need to use ldap in the clients themselves
12:23
<SYS64738>
alkisg: clients
12:23
<alkisg>
The clients use LDM, the ltsp display manager
12:24
LDM uses ssh. It's not configurable. It can't use ldap directly.
12:25
<SYS64738>
ok
12:26
but when try to login from ldm:
12:26
Apr 12 14:18:29 srterserlinux01 systemd-logind[1736]: New session 14 of user fdurso.
12:26

12:26

12:26
Apr 12 14:18:33 srterserlinux01 sshd[6631]: Received disconnect from 192.168.112.11 port 58094:11: disconnected by user
12:26
the keyring thing is a warning or is the error that cannot make me login
12:26
?

<ltsp>
screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
12:36
<alkisg>
SYS64738: get a root shell on the client like this ^
12:36
Then try this: ssh <user>@server
12:36
Replace only <user> in that command. Leave the name "server"
12:36
See if you can login that way
12:36
If you can't, it's a misconfiguration on your part
12:38
<SYS64738>
do you mean AD_user@IP.SERVER ?
12:38
(ssh)
12:38
https://nopaste.me/view/711cf480
12:39
<alkisg>
ssh AD_user@server
12:39
Don't use the ip
12:40
The ltsp clients contact the server at the dns name "server"
12:40
<SYS64738>
it works
12:40
<alkisg>
So you do want to use exactly the word "server" at that command
12:40
Can you paste /var/log/ldm.log from the client?
12:40
cat /var/log/ldm.log | nc termbin.com 9999
12:41
And also check /var/log/auth.log on the server
