alkisg: hello :) did u know something about a way to store a session if user has a active login and the thinclient power switch off?
05:19vmlintu has joined #ltsp
05:20
<alkisg>
zeitsofa: no, I don't know anything like that in ltsp. nx supports it though.
05:21
<zeitsofa>
is there a way to combinate nx and ltsp to do this?
05:22
<alkisg>
You could make a different login screen that uses nx... but I don't know anyone that has done it.

good morning all
10:27
I have a question regarding the setup of my LTSP server. We set up the server and a single app server. The first time I load up a new thin client, it logs into the app server correctly, but then on every subsequent boot, the thin clients are logging into the ltsp server instead of the app server.

<EricLMG>
could someone please help with an issue i am having with my ltsp server? for some reason, my thin clients are being directed to the ltsp server instead of the app server, and I can't figure out why
11:08Faithful has joined #ltsp
11:13
<Appiah>
" directed" ?
11:15
<alkisg>
EricLMG: distro/version/lts.conf/dhcpd.conf?
11:15
<mhull>
alkisg, i'm with EricLMG... we are using the ltsp loadbalancer
11:17
the thin clients connect to the application server as they should be once, but after they've been defined in the ltsp-cluster admin page, they always connect to the actual ltsp load balancing server rather than the app server
11:17
<alkisg>
The LTSP-cluster loadbalancer? Or a custom loadbalancer implementation, like it's documented in https://wiki.ubuntu.com/LDMLoadbalancingSupport ?
11:17
OK, sorry, no idea about ltsp cluster
11:18
<EricLMG>
its exactly as documented in wiki
11:20
<alkisg>
I'm seeing on ldm.c that some info is logged about the balancing
11:20
So, check ldm.log locally, maybe you'll find some clues there
11:21
loginfo("IP before balancing: %s",ldm.server); // loginfo("Balancing failed to get an IP"); // logerr("Balancing failed"); etc

11:24
<alkisg>
Also check what "getltscfg-cluster -l ldm" tells you (again locally)
11:26
<mhull>
getltscfg-cluster -l ldm returns nothing
11:27
any idea what this might be: "code 400, message Bad request syntax ('getkey')"
11:28
that's showing up in ltsp-cluster-lbserver.log

hey guys, configuring ltsp on ubuntu. Everything seems to be working fine, up til client login. It authenticates, then throws "getpwuid_r(): failed due to unknown user id (0)" Any ideas what might cause it?
12:55vagrantc has joined #ltsp
13:00
<atkuepker>
Grindar, What authentication method are you using?
13:02rad4Christ has quit IRC
13:03
<Grindar>
whichever one was configured by default?
13:03
I was following the ubuntu wiki on it
13:03rad4Christ has joined #ltsp
13:03
<atkuepker>
did you run the ltsp-update-sshkeys and ltsp-update-image after the install?
13:04
<Grindar>
yes
13:04
before I did that the login itself was timing out, now it seems to putter out when launching X
13:04
<atkuepker>
ah, that's different from a login failure.
13:05
<Grindar>
any ideas on what to look at? googling has helped much yet
13:05
*hasn't
13:07mikkel has quit IRC
13:07
<atkuepker>
if you're having X problems, the .xsession-errors file will probably be needful.
13:08
Those issues are sometimes difficult to sort out though. Unlike most folks, we've had an awful time here dealing with i845 Intel video drivers
13:11
<Grindar>
where would that file be stashed?
13:12
<atkuepker>
home directory of the user that's logging in
13:12Faithful has quit IRC
13:12
<Grindar>
ok, checking it now
13:15
hmm, I don't see that file, or anything close to that
13:16
in fact, my home directory has nothing but the default folders
13:17
<atkuepker>
did you specify the file or use the '-a' flag?
13:18
<Grindar>
ah, -a did it.
13:20
"please ask your system administrator to enable user sharing."
13:20
<atkuepker>
can't help you with that one. We have that stuff turned off for HIPAA compliance.
13:20
<Grindar>
HIPAA?
13:21
<zeitsofa>
hello :) my thinclients always have 800x600 but in the ltsp.conf X_MODE_0 = 1024x768. it's a bug oder user error?
13:21
<Grindar>
actually, that doesn't seem to be cause of crash...it's earlier. trying to copy from virtual machine :p

13:37
<alkisg>
zeitsofa: the monitor frequencies are probably not detected correctly. What graphics card / monitor does your client have?
13:38
<zeitsofa>
alkisg: monitor atm is an old NEC LCD 2010 - and graphic card i don't know atm
13:38
<alkisg>
Do you know the correct resolution for your monitor? E.g. 1024x768@60Hz?
13:40
<zeitsofa>
yes its true
13:41
<Grindar>
let me reboot my thin client and I'll give it a shot
13:41
<alkisg>
Grindar: a logoff should suffice
13:41
<Grindar>
not when it was frozen >.<
13:41
<alkisg>
Heh ,ok
13:42
zeitsofa: try putting those in your lts.conf:
13:42
[Default]
13:42
X_HORZSYNC=30.0-88.0
13:42
X_VERTREFRESH=59.0-61.0
13:43winthrowe has quit IRC
13:43
<alkisg>
XRANDR_MODE_0=1024x768
13:43
<Grindar>
wait a minute, am I disabling compiz on the thin client image or the server, or both?
13:43
<alkisg>
Then reboot the client and see if it works.
13:43
Grindar: if you're using thin clients (as opposed to fat), then just on the server.
13:43
<zeitsofa>
alkisg: thx i'll try
13:46
<Grindar>
ok, entered the command, trying it :p
13:48
<zeitsofa>
alkisg: looks little bit better - the font is very very small now
13:48
<alkisg>
zeitsofa: open a gnome terminal, and enter: xrandr
13:48
You'll see the active mode and the available modes.
13:49
<zeitsofa>
ah ok
13:49
1024x768 61.0
13:50
<alkisg>
That's all? No other modes? Do you also have an X_MODE_0 in your lts.conf?
13:51
<zeitsofa>
just a moment i'll create a nopaste
13:51
<Grindar>
ok, trying again, but nothing happened after I disabled compiz
13:52
went to a terminal screen that was basically frozen with a spinning white circle (hourglass equivalent)
13:54
<zeitsofa>
alkisg: http://nopaste.info/b4fb4c8793.html
13:56
<Grindar>
yep, did the same again
13:56
<alkisg>
zeitsofa: ok, if you think that 1024x768 is not appropriate, you can try different modes from System > Preferences > Monitor settings (or similar - I don't have english menus)
13:57
<zeitsofa>
alkisg: german?
13:57
<alkisg>
zeitsofa: also, do you need XSERVER=vesa?
13:57
If you remove that, maybe it'll correctly autodetect your monitor
13:57
No, Greek
13:57
<zeitsofa>
alkisg: i turn it of but it is the same
13:57
<alkisg>
Do turn it off then, it's faster without vesa
13:58
Grindar: does your server have a GUI? Or is it headless?
13:59
<zeitsofa>
ok i found a good solution for me :)
13:59
<Grindar>
server has a gui
13:59
<zeitsofa>
thx a lot
13:59EricLMG has quit IRC
14:00
<alkisg>
Grindar: try logging in on the server with that user
14:01
<Grindar>
yep. not a problem there
14:04
<alkisg>
OK, try to collect some extra info
14:04
auth.log from the server,
14:04
ldm.log from the client,
14:04
~/.xsession-errors etc
14:05
<Grindar>
you want me to pastebin them?
14:06
<alkisg>
Not the whole auth.log - just see that each time a user tries to connect on a client, you actually get a successful authentication there
14:06
I think you can pastebin the other 2 :)
14:08
<Grindar>
ok, here's the xsession errors
14:08
glib-critical **:g_once_init_leave:assertion 'initialization_value !=0' failed
14:08
oops, un momento :p
14:09
http://pastebin.com/eQxGfHNh
14:10
silly can't copy between my lappy and the virtual machine...
14:10
ok, looking for the rest
14:10* alkisg needs to go AFK for an hour...
14:12
<Grindar>
and I leave work in less than that, oh well

hi
15:43
I have some old thin client which only support RDP protocol.. I have Linux Server , What Software/Server I should install for thin client setup.
15:43
Or may you guide for better IRC channel
15:44
<alkisg>
LTSP sends its own OS to the clients, so they'll support other protocols too.
15:44
Don't they support PXE booting?
15:44
<Appiah>
PXE boot the thin client
15:44
and it wont matter
15:46

<alkisg>
How's Debian comparing to Ubuntu for your LTSP setups?
15:50
<Lns>
I haven't tested 35 clients on debian yet but the 2 i have in my office are working out well
15:51
nothing to complain about
