Hello, is anyone here online? I need to ask a couple questions

<gravityshift>
On my school we are using ubuntu 12.04 ltsp that is provided from the center of education in my capital city. We need to make one for our personal environment without having the "Classroom Controll" administration panel and having something else. I have tried using some video tutorials on ltsp but nothing worked. Will the guides from your site help me establish it?
10:20
<alkisg>
What is the classroom control administration panel?
10:21
<gravityshift>
its in the ltsp that is provided from our university that is responsible for all the administration across my country for school ltsp. its a program that you can controll all thin clients, shut down, vnc, view screen write in them chat etc
10:21
we are using epoptes and classroom control programs for administration
10:22* alkisg didn't understand the question
10:22
<alkisg>
I do know epoptes, I'm one of the developers, but I didn't understand what you're asking
10:23
<gravityshift>
I'm asking an ltsp solution to use on my private network and in small business without having the "Classroom Control" program inside ltsp that is to administrate the clients. I want some other software because this is provided by school network and its not allowed to use in business and others
10:24
<alkisg>
You want an alternative to a program that we've never heard of?
10:24
You need to define it then, I don't know what this classroom control program offers you
10:25
Suppose you install LTSP and epoptes. What other functionality do you want?
10:28
<gravityshift>
the ltsp that is provided to us is custom made and we are not able to change it, the environment is combined: epoptes and classroom control, as i see now the program is exactly like this but with some changes, http://goo.gl/eEAuk7 , we know its epoptes but we cant figure out how to make the whole ltsp to be working in a small business/home without having the restrictions/software/modifications of the school network that is provide
10:28
describe it
10:29
<alkisg>
gravityshift: I see that you're greek, are you talking about the ltsp version provided by http://ts.sch.gr/wiki/Linux/LTSP ?

hi
12:36
I would like to know if it's possible select at client boot if you want to run as a thin-client or a fat-client
12:37
I know it's possible to configure lts.conf to select it by MAC address, but what I want is choose it at boot
12:37
thanks in advance

hello all
18:18* vagrantc waves
18:18
<Duann>
my name is Duann. i'm brazilian and new in linux world.... anyone can help me to configure a ltps server in debian?
18:19
<vagrantc>
what have you tried so far? having troubles?
18:20
<Duann>
i make the server... is running... but
18:21
i can't configure the sound and usb at stations
18:22
ah... sorry for my bad english :(
18:23
i used this command: LOCALDEV=true and SOUND=true, but not have effect
18:24
<vagrantc>
what distro?
18:24
<Duann>
debian 7
18:24
<vagrantc>
so localdev and sound should be enabled by default
18:24
<Duann>
my lts.conf:
18:24
[default] LTSP_CONFIG=True SOUND=true LOCALDEV=true LOCALDEV_DENY_USB=false CONFIGURE_X=True X_MODE_0=1366x768 XkbModel=ABNT2 XkbLayout=br
18:25
<vagrantc>
there are some known issues with sound on debian wheezy ... which i should fix.
18:25
<Duann>
OMG....
18:25
<vagrantc>
localdev, localdev_deny_usb sound and configure_x shouldn't be needed.
18:25
they're the default
18:26
<Duann>
uhmm
18:26
<vagrantc>
the workaround is really a one-line patch, if i remember correctly
18:27
<Duann>
u can help me for it?

vagrantc, on ubntu i had to add ltsp-users to the fuse group to be able to use usb storage devices on clients
18:30
<vagrantc>
Ark74: ah, yes, that's true for debian as well
18:30
Duann: be sure to add users to the fuse group if you want localdev to work

Good evening! Can you please help to solve the following problem:
19:50
My LTSP clients are booting, and I can see the LDM login screen. But no user is able to login - in the .xsession-errors I found the following:
19:50
** (gnome-session:7638): WARNING **: Anzeige kann nicht geöffnet werden:. Xsession: X session started for om at Do 3. Apr 21:18:46 CEST 2014 xrdb: Can't open display '' xhost: unable to open display "" xhost: unable to open display "" Setting IM through im-switch for locale=de_DE. Start IM through /etc/X11/xinit/xinput.d/all_ALL linked to /etc/X11/xinit/xinput.d/default.
19:50
I have no idea - maybe you? Thanks in advance!
19:52
<vagrantc>
which distro?
19:52
<fauxxami>
Sorry: Ubuntu 12.04
19:52
<vagrantc>
do you have a desktop environment installed on the server?
19:53
<fauxxami>
Yes, and i can login locally.
19:55
The message above appears each time I try to authenticate. Authentication is successfull - says /var/log/auth.log
19:55
<vagrantc>
my guess is it's not falling back to the non-accelerated desktop or something, but i'm not sure
19:55
fauxxami: have you tried logging in with a different session type?
19:55
fauxxami: you can select session types from the LDM menu in the lower left
19:56
<fauxxami>
Yes: the session types offered in LDM are: Default, XTerm, Ubuntu and Ubuntu 2D - nothing works.
20:00
<vagrantc>
did it ever work?
20:02
<fauxxami>
No, I freshly installed LTSP today.
20:02
I'm running perfectly LTSP on another server and I don't understand where's the problem here ...
20:03
If I enter my username and password, LDM is disapperaring for a short moment and then it reappears.
20:05
<vagrantc>
does the user successfully authenticate via ssh?
20:05
see in /var/log/auth.log
20:07
<fauxxami>
Yes, he does: please look at the log messages:
20:07

fauxxami: sounds like you might have X11 forwarding disabled?
20:09
<fauxxami>
I active it in /etc/ssh/sshd_config?
20:09
<vagrantc>
fauxxami: look in /etc/ssh/sshd_config: X11Forwarding
20:09
<fauxxami>
Yes, one moment ...
20:10
X11Forwarding is set to "Yes".
20:11

is xauth installed?
20:11
<fauxxami>
Yes, it is.
20:11
<vagrantc>
x11-xserver-utils ?
20:12
<fauxxami>
Yes, also.
20:12
But in two versions:
20:12
ii x11-xserver-utils 7.6+3 X server utilitiesii x11-xserver-utils-lts-saucy 7.7+0ubuntu2~precise1 X server utilities
20:16
<vagrantc>
https://www.linuxquestions.org/questions/linux-networking-3/ssh-x-cannot-open-display-925852/
20:16
not sure if that's related...
20:16
fauxxami: can you log into the server through the GUI and try:
20:17
ssh -X om@127.0.0.1 xterm
20:17
does it work?
20:19
is ipv6 off?
20:22
<fauxxami>
Yes, ipv6 is off. Problem: I'm working in my school, and I forgot the key for the server room at home ... :-( So I have to try ssh -X tomorrow morning ... If it's not working - do you have an idea?
20:26
Ok, perhaps it's time to go home now. I really appreciated your help - I will re-read the document tomorrow and I will also try ssh -X locally. For now: thank you an bye!
20:27
<vagrantc>
fauxxami: try in sshd_config: AddressFamily inet
20:31
<fauxxami>
I tried, but without success.
20:31* vagrantc is out of ideas
20:31
<fauxxami>
Again: thank you!
20:31
<vagrantc>
hope you figure it out!
20:32
<fauxxami>
Tomorrow - I've been working for 13 hours now, perhaps it's enough. :-)
