Hi everyone. Anyone here to give me some tips with my ltsp installation?
Im trying to do the following:
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
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?
Are you sure the program can handle multiple users?
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
It is portable, but it does have to write to it's own directory
To its own directory or to the current directory?
the program can handle multiple users, it is supposed to be opened by several users via a windows network share
It is a .exe file and it will write to the directory where the .exe is in
Will it be a possible solution to use a remote app with the sudo -u way?
Then you could probably put all those users in a group and make that directory group-writable
Thin or fat clients?
Thin clients can use sudo -u
Fats, usually no, you should do it with a group instead
but am i mistaken that with the "remote app" thing, the command will be run on the server itself?
i saw it here somewhere: http://www.epoptes.org/documentation/fat-clients
Why do you want to run it as a remoteapp?
The program is very slow when multiple clients run on the same single directory over network
Then you're essentially using thin clients, not fat, for that program
I.e. you can use sudo -u and the rest
thats the reason i wanted to use a terminalserver, so all the writing to the directory would be on one local machine
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 =)

i have a question concerning lts.conf
|11:30||khildin has left IRC (firstname.lastname@example.org, Ping timeout: 240 seconds)|
i have an lstp-server running on xubuntu
i am using fat clients as described here: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
but when i generate an lts.conf file in /var/lib/tftpboot/ltsp/amd64/lts.conf, it will not get to the clients

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
getltscfg -a tells me that there is no such file as /etc/lts.conf
did i do something wrong?
|11:35||vsuojanen has left IRC (email@example.com, Remote host closed the connection)|
i did restart the services before booting the client ofc

Gasp0de: did you sent a mail to edubuntu-users ml?
No. Shall I?
No, I just replied there 2 minutes ago in a similar issue
Try this: sudo ln -s amd64 /var/lib/tftpboot/ltsp/i386
Then reboot the clients
ok. should i do this while in /var/lib/tftpboot?
is rebooting enough or do i have to run some update script or restart nbd-server?
just reboot clients
ok the file seems to exist now, but i get a permission error when running getltscfg
put screen_02=shell in lts.conf to get a root shell
screen_02: To get a root shell on an Ubuntu thin client: https://help.ubuntu.com/community/UbuntuLTSP/ClientTroubleshooting#Using_a_shell_SCREEN
alright, thank you
i can run remote apps now =)
Gasp0de: your clients are amd64, right?
I wonder why that bug exists
If you can, paste the contents of the files in /var/run/ltsp/* from your fat client
pastebin: the LTSP pastebin is at http://ltsp.pastebin.com. Please paste all text longer than a line or two to the pastebin, as it helps to reduce traffic in the channel. Don't forget to paste the URL of the text here.
sry i was gone for a second
yes my client is amd64
i will paste the contents, give me a minute
the directory doesn't exist
Gasp0de: sorry, /var/cache/ltsp
I will have a look
in the meantime, i've already got another question
i managed to start apps remotely now
but sudo wont work yet, and i don't know why
ltsp-remoteapps mousepad will start mousepad as a remoteapp correctly
while ltsp-remoteapps mousepad wont
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.

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
So I'm guessing you're correct and I never tried NLA
