Hi everyone. Anyone here to give me some tips with my ltsp installation?
09:38
Im trying to do the following:
09:40
I have set up an ltsp server on xubuntu, and i can boot into it, so far everything is great. Now, i want the users to be able to start a wine program. Wine and the program work fine, yet i need all of the users to work on the same directory. The suggested way to do this is to create a wine user, and then have all users start wine as the wine user using sudo -u
09:41
as far as i know, this will not be a good solution for running it on the clients, e.g. i don't know if it's possible, or advisable, to use sudo -u on a client?
09:42
<alkisg>
Are you sure the program can handle multiple users?
09:42
If it's a portable program that doesn't need to write to its own directory, put it in /usr/share/app and create a launcher
09:44
<Gasp0de>
It is portable, but it does have to write to it's own directory
09:44
<alkisg>
To its own directory or to the current directory?
09:44
<Gasp0de>
the program can handle multiple users, it is supposed to be opened by several users via a windows network share
09:45
It is a .exe file and it will write to the directory where the .exe is in
09:45
Will it be a possible solution to use a remote app with the sudo -u way?
09:45
<alkisg>
Then you could probably put all those users in a group and make that directory group-writable
09:46
Thin or fat clients?
09:46
<Gasp0de>
fat
09:46
<alkisg>
Thin clients can use sudo -u
09:46
Fats, usually no, you should do it with a group instead
09:46
<Gasp0de>
ok
09:47
but am i mistaken that with the "remote app" thing, the command will be run on the server itself?
09:47
i saw it here somewhere: http://www.epoptes.org/documentation/fat-clients
09:47
<alkisg>
Why do you want to run it as a remoteapp?
09:48
<Gasp0de>
The program is very slow when multiple clients run on the same single directory over network
09:48
<alkisg>
Then you're essentially using thin clients, not fat, for that program
09:48
I.e. you can use sudo -u and the rest
09:48
<Gasp0de>
thats the reason i wanted to use a terminalserver, so all the writing to the directory would be on one local machine
09:50
Ok thanks so far i will try that way and then come back here if i have more questions or to leave my success story =)
09:50
<alkisg>
You're welcome

Hi everyone
11:30
i have a question concerning lts.conf

11:30
<Gasp0de>
i have an lstp-server running on xubuntu
11:31
i am using fat clients as described here: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
11:32
but when i generate an lts.conf file in /var/lib/tftpboot/ltsp/amd64/lts.conf, it will not get to the clients

<Gasp0de>
i shut down the services dnsmasq and nbd-server, then ran 'sudo /usr/share/ltsp/update-kernels' and 'sudo ltsp-update-image --cleanup /', then booted the client
11:34
getltscfg -a tells me that there is no such file as /etc/lts.conf
11:34
did i do something wrong?

<Gasp0de>
i did restart the services before booting the client ofc

<alkisg>
Gasp0de: did you sent a mail to edubuntu-users ml?
11:40
<Gasp0de>
No. Shall I?
11:40
<alkisg>
No, I just replied there 2 minutes ago in a similar issue
11:41
Try this: sudo ln -s amd64 /var/lib/tftpboot/ltsp/i386
11:41
Then reboot the clients
11:41
<Gasp0de>
ok. should i do this while in /var/lib/tftpboot?
11:41
<alkisg>
Wherever
11:42
<Gasp0de>
ok
11:43
is rebooting enough or do i have to run some update script or restart nbd-server?
11:43
<alkisg>
just reboot clients
11:43
<Gasp0de>
ok
11:45
ok the file seems to exist now, but i get a permission error when running getltscfg
11:45
<alkisg>
it's normal
11:45
put screen_02=shell in lts.conf to get a root shell
11:45
!screen_02
11:45
<ltsp>
screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
11:46
<Gasp0de>
alright, thank you
11:46
i can run remote apps now =)
11:47
<alkisg>
Gasp0de: your clients are amd64, right?
11:48
I wonder why that bug exists
11:48
If you can, paste the contents of the files in /var/run/ltsp/* from your fat client
11:48
!pastebin

11:54
<Gasp0de>
sry i was gone for a second
11:54
yes my client is amd64
11:54
i will paste the contents, give me a minute
11:56
the directory doesn't exist
12:08
<alkisg>
Gasp0de: sorry, /var/cache/ltsp
12:12
<Gasp0de>
I will have a look
12:12
in the meantime, i've already got another question
12:12
i managed to start apps remotely now
12:13
but sudo wont work yet, and i don't know why
12:13
ltsp-remoteapps mousepad will start mousepad as a remoteapp correctly
12:13
while ltsp-remoteapps mousepad wont
12:16
sry
12:17
ltsp-remoteapps 'sudo mousepad' is the one that doesnt work

alkisg: I couldn't get the xfreerdp -f -u '' graphical login prompt with Windows 7 + NLA.
13:19
if I understand it's said also in FreeRDP manual.

Gasp0de: you need a terminal to enter the sudo password, make a script or use gksudo or pkexec etc
14:53
ROOTPATH='/opt/ltsp/amd64' and filename=''... hmm....

vsuojanen: I don't remember how I tested, but what I was seeing in windows 2008 server, was the login screen mentioned in " Old Authentication" paragraph from the page you've linked
15:03
So I'm guessing you're correct and I never tried NLA
