<ltspuser_08>
Hello guys, need assistance with LTSP and RDP
06:15F-GT has joined IRC (F-GT!~phantom@ppp59-167-136-109.static.internode.on.net)
06:16
<ltspuser_08>
I have a LTSP installation using Ubuntu 12.04 LTS
06:16
I have configured the clients to automatically connect to rdp on the start of a client.
06:16
they can work fine without issue.
06:18
the problem only comes when the RDP session is logged off the thin clients xserver gets reset and the
06:18
client gets the login screen again.
06:18
What I would have normally liked is once the client logs off the thin client should shut down
06:18
is there a way to get this issue sorted
06:18
?
06:19
<alkisg>
So you really want the clients to be able to login only once?! If so, just make a $CHROOT/usr/local/bin/xfreerdp wrapper that shuts down after calling /usr/bin/xfreerdp.
06:21
<ltspuser_08>
What i require is when the client logs off from the RDP session, the thin client should maybe either prompt him to shutdown or relogin / shutdown completely....
06:21
<alkisg>
OK, then do what I said
06:21
Relogin?
06:22
Isn't that what it currently does? Try to relogin in windows with xfreerdp?
06:23bauerski has joined IRC (bauerski!~witekb@frodo.psp.opole.pl)
06:23
<ltspuser_08>
sorry for the stupid question
06:24
@alkisg: please can you advice how do i
06:24
If so, just make a $CHROOT/usr/local/bin/xfreerdp wrapper that shuts down after calling /usr/bin/xfreerdp.
06:24
<alkisg>
sudo gedit /opt/ltsp/i386/usr/local/bin/xfreerdp
06:24
contents:
06:24
#!/bin/sh
06:24
/usr/bin/xfreerdp "$@"
06:24
poweroff
06:24
save, exit, run sudo ltsp-update-image, reboot clients
06:26
<ltspuser_08>
I dont have xfreerdp under /opt/ltsp/i386/usr/local/bin/xfreerdp
06:26
I only have it under
06:27
/usr/bin/xfreerdp
06:27
/usr/bin/xfreerdp
06:27
<alkisg>
Yes, that one under local is the wrapper that you'll create with gedit
06:27
<ltspuser_08>
/usr/bin/xfreerdp
06:28
<alkisg>
But I forgot one command before the ltsp-update-image, you need to make the wrapper executable by running:
06:28
sudo chmod +x /opt/ltsp/i386/usr/local/bin/xfreerdp

06:34
<ltspuser_08>
@alkisg my appologies but I am trying to create the file
06:34
it just doesnt want to create that file for some reason
06:35shogunx has left IRC (shogunx!~shogunx@2001:4978:106:1:f8c0:e599:d577:43be, Ping timeout: 260 seconds)
06:35
<ltspuser_08>
I have done
06:35
sudo gedit /opt/ltsp/i386/usr/local/bin/xfreerdp
06:36
put in the code you gave me, trying to save the file it doesnt want to save
06:36
seems it isnt saving because the folder after /opt/ltsp dont exist
06:40
<alkisg>
ltspuser_08: are you running this on your server?
06:40
Or on the client?
06:41
<ltspuser_08>
I am on the server
06:41
sshed into the server
06:41
<alkisg>
What's the output of `ls /opt/ltsp` on the server?
06:42
<ltspuser_08>
images
06:42
<alkisg>
So you don't have an ltsp chroot
06:42
How did you get the clients to boot without an ltsp chroot?
06:42khildin has joined IRC (khildin!~khildin@ip-80-236-228-19.dsl.scarlet.be)
06:43
<ltspuser_08>
i think all the files are by default on /var/tft///////
06:43
<alkisg>
No, those are the files for tftp
06:43shogunx has joined IRC (shogunx!~shogunx@2001:4978:106:1:f8c0:e599:d577:43be)
06:43
<alkisg>
You also need the chroot, the one that ltsp-build-client creates
06:44
<ltspuser_08>
/var/lib/tftpboot/ltsp/i386/
06:45
is this what we are looking for?
06:45
<alkisg>
No, see my previous comment
06:45
You should have an /opt/ltsp/i386 or an /opt/ltsp/amd64 dir as well
06:45
With a whole "minimal installation" there, called the chroot, which is created by ltsp-build-client
06:46
What 's the output of this command on your server?
06:46
egrep -rv '^#|^$' /etc/nbd-server/
06:47
<ltspuser_08>
egrep -rv '^#|^$' /etc/nbd-server/
06:49
this is the manual i used to install LTSP
06:50
https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
06:50
<alkisg>
Ah
06:50
For xfreerdp? Why?
06:50
<ltspuser_08>
the output of egrep -rv '^#|^$' /etc/nbd-server/
06:50
<alkisg>
OK never mind about the whole /opt/ltsp discussion then
06:50
<ltspuser_08>
is /etc/nbd-server/config:[generic]
06:50
<alkisg>
Go back to the things I said about the wrapper, but do them in /, not in /opt/ltsp/i386
06:51
So, run: sudo gedit /usr/local/bin/xfreerdp etc etc
06:52
When you're done, run: sudo chmod +x /usr/local/bin/xfreerdp; sudo ltsp-update-image -c /
06:53
But you shouldn't be using ltsp-pnp for just xfreerdp clients, in the wiki page it mentions that this is better suited to ltsp fat clients that have a whole ubuntu desktop on them
06:53
Anyways, since you already done that, np

Ah, the one with udhcpc? Did you purge your chroot and create a new one?

You're still sending the old kernel

Did you run ltsp-update-kernels/ltsp-update-image etc?

that command is new to me

just ltsp-update-image, i'm afraid

Start with:

i guess i have to run all of these again, yeah?

in what order? does that matter?

alkisg: can you find the error?
20:37
<alkisg>
zamba: it appears to be in the last stages, of ltsp-update-kernels
20:37
So the chroot should be ok
20:37
Try this: sudo ltsp-update-kernels
20:37
<zamba>
looks like it completed
20:37
<alkisg>
zamba: ok, move on to sudo ltsp-update-image
20:39
<zamba>
full disk :)
20:40
<alkisg>
Do file a bug report though that ltsp-build-client didn't report that
20:41
<zamba>
ltsp-update-image reported that
20:41
<alkisg>
ltsp-build-client runs ltsp-update-image internally
20:41
So it should be reporting that, but it doesn't
20:45
<zamba>
oh, i'm so tired of error i'm the only one getting
20:46
errors*
20:51
now i can't mount cifs shares
20:51
if i specify iocharset it fails like so:
20:52
mount error(79): Can not access a needed shared library
20:52
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
