hi!
10:13
what is the version of ltsp in debian sid right now?
10:14
I can't seem to get it from the package...
10:14
<ogra>
ltsp5 pre
10:14
as in ubuntu
10:16
<rafiks>
thanks ,ogra..are you one of the package maintainer?
10:16
<ogra>
yes, and one of the upstream authors
10:16
err ... not for debian though ...
10:16
but for ubuntu ...
10:17
but they are essentially the same
10:17
<rafiks>
there doesn't seem to be much documentation in the debian package..
10:17
<ogra>
debian is lacking some features that didnt make it in before the freeze
10:17
<rafiks>
esp the installation part..
10:18
are these features essential?
10:18
<ogra>
https://help.ubuntu.com/community/UbuntuLTSP
10:18
especially https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
10:18
well, its things like local device access for usb drives etc
10:19
if you dont need that or can wait for a backported ltspfs package then its fine
10:19
<rafiks>
ok..will try that link..I think i see a ltspfs package in unstable
10:19
<ogra>
ah, might be that it made it into unstable but doesnt get included into etch ...
10:20Skarmeth has joined #ltsp
10:21
<rafiks>
i was wondering about ltspfs ,so this is a fuse FS ,,what does it do?
10:21
how is this differnt from nfs?
10:22
<ogra>
you can just uplug devices without unmounting them ...
10:22
<moquist>
ogra: I'm looking at purge_processes from k12ltsp, wanting the same kind of thing in edubuntu (to purge all of a user's processes at login, and again at logout). But this doesn't seem quite as straightforward on edubuntu, since everything's running through an sshd process in the first place...we'd have to kill everything *but* that. Any comments?
10:22
<ogra>
fuse is a userspace FS, has not much in common with nfs
10:23
moquist, thats a bad idea since it will hide the real bugs ... i want the apps to be fixed to terminate properly rather
10:23
<moquist>
ogra: I don't disagree with the goal, but I have slow and slowing systems *NOW*. :\
10:23
<ogra>
we should make some propaganda so admins check which processes are left
10:23
<moquist>
gnome-session
10:23
<rafiks>
ogra:like automount ?
10:23
<moquist>
all over the place
10:24
<ogra>
rafiks, similar, yes ...
10:24
moquist, as a workaround you could install slay and kill the users processes on login indeed, but that would wipe dual logins for example
10:25
<moquist>
ogra: it shouldn't be difficult to write something that cron could run in the middle of the night to check for persisting regular user processes and produce a report.
10:25
<ogra>
i.e. from an Xsessin.d script that gets executed before gnome-session is started
10:25
<moquist>
ogra: Right; I'm more than ready to give up dual logins.
10:25
ogra: wasn't aware of slay.
10:26
<ogra>
ok, then just have a look at /etc/X11/Xsession.d/80_ltsp-sound
10:26* moquist is becoming aware
10:26* moquist nods
10:26
<ogra>
should probably have a 10 as sequence # instead
10:26
<rafiks>
ssh is used in muekow right,,is this gonna be an issue with thin clients with slower cpu?
10:27
<ogra>
no, but with slow servers
10:27
<rafiks>
ahh ,so the ssh client is still running on the server?
10:28
<ogra>
the encryption takes some extra cycles on the server side, if you have many clients that can slow it slightly down
10:28tiagovaz has joined #ltsp
10:28
<ogra>
no, its also running on te client ... but there are no significant slowdowns on that side ... the server side is more critical
10:29
<rafiks>
k,well i am just using a 1 client setup for my personal home network,don't know if LTSP is overkill..
10:29
for this ..
10:30
<ogra>
no, it isnt :)
10:30
i'm using my laptop as my server and have a thin client as my main workplace ... together with x2x via ssh thats a really comfortable setup ;)
10:31
its better than buying an expensive docking station ;)
10:31
<rafiks>
cool! a laptop for a server!
10:31
<ogra>
well, my laptop is my most powerful system i have :)
10:32
<rafiks>
btw,LTSP is on a chroot,how do i use the same user account on the host system?
10:32vanya has quit IRC
10:33
<ogra>
you dont use any accounts on the client system ...
10:34
the login you do is on tha server ... the client only starts X and the login manager ... the login manager then does "ssh -X user@server Xsession"
10:35
<rafiks>
ahh,i c..is there an autologin for ldm?
10:38
<ogra>
nope
10:38jammcq has joined #ltsp

yo
10:38

not yet ...
10:38
patches acceted ;)
10:38
<moquist>
jammcq!!!!!!!!!!
10:38
<ogra>
*accepted as well :)
10:38
hey jammcq
10:38
<jammcq>
hey kids
10:39
<moquist>
ogra: er, adding a 10_ltsp-slay to Xsession.d runs slay $USER which runs slay $USER which runs slay $USER which runs... 8-/
10:39
<ogra>
ah
10:39* moquist isn't sure why yet
10:39
<ogra>
well, then pkill gnome-session ?
10:39
instead of slay ?
10:40* jammcq says it's too early in the morning for recursion
10:40
<moquist>
ogra: Yeah, but gnome-session isn't the *only* guilty process.
10:40
<ogra>
slay is actually a bad idea in this case since it kills your ssh session as well
10:40
<moquist>
Just the most egregious.
10:40
<ogra>
sorry for the wrong hint
10:40
<moquist>
ogra: Right; that's what I thought, but I figured "Ogra knows everything, I'll try what HE says..." ;)
10:40
<ogra>
ps aux|grep $USER ?
10:41
ps aux|grep $USER |grep -v ssh |grep -v grep
10:41
<moquist>
pkill -u would be fine except that the ssh process has to be eliminated.
10:41
ogra: something like that, yes.
10:41
I used to type something very similar to that all the time, until one day (at NELS) gadi said "WHAT are you doing?!? Use 'kill'." I said "pkill?" And then I learned.

10:42
<moquist>
ogra: I'm leaning toward a short script that's very adept at killing all my processes EXCEPT itself and its parent(s). That would do the trick.
10:43
<rafiks>
ogra: i was reading the LTSPwiring page..it says that "make sure there is no dhcp server running on the router"
10:43
<moquist>
ogra: Yeah. Then I learned about pkill. This happened last June.

turns out I'm running one...
10:43

moquist, just joking :)
10:43

If I'd come across pkill before, I'd forgotten it. Every time. :\
10:43
ogra: :)

<rafiks>
I have openwrt on my router...
10:44
can I setup the dnsmasq in the openwrt as mr dhcp server?
10:44
my
10:44
<ogra>
rafiks, well, if you can configure the dhcp server on your router to server PXE stuff, then you can indeed use that one ... else i'd just disable the routers one ...
10:45
running two dhcpds is not a good idea if you do netbooting
10:45
<rafiks>
is there a way to point the dhcp in the router the pxe config on my server?
10:45
<ogra>
dont install ltsp-server-standalone then, but only ltsp-server
10:45
-standalone adds the dhcpd bits
10:46
<rafiks>
ok..

<MoL0ToV>
hi to all, someone know if is possibile to make a thin client school lab with tlsp and then use the thin-client usb ports on the thin-client?
11:11
<ogra>
MoL0ToV, if you use edubuntu that will work out of the box ...
11:12
it configures ltsp for you during install and supports local devices on the clients by default
11:14
<MoL0ToV>
ogra, ok i try. i also tryed with debian-edu, but when i install with graphical installer, the wizard don let me partitioning the system and leave the first partition intact
11:14
now i ask on #debian
11:14
thanks!
11:15
<ogra>
if you try edubuntu just make sure to not install from the liveCd it doesnt have ltsp on it ... use the installer iso ...

you should use the subprocess module instead of popen ... its safer
13:07
what about the time.sleep ? is that really needed ? i'd suspect you kill processes of the upcoming session ths way

I wanto to demo an ltsp server to a small school and have a couple questions :)

how well supported is opensuse? Ive been told it is very cute and polished, and I am affraid that is also an important selling point, even if it's free vs new windows machines

I overwrote a user's home folder with an older copy
16:40
Upon logging in, this error comes up "User's $HOME /.dmrc file is being ignored.
16:40
This prevents the default session and language from being saved.
16:40
File should be
16:40
owned by user and have 644 permissions. User's $HOME directory must be owned by
16:40
user and not writeable by other users."
16:40
I already tried the chmod 644
16:40
I tried to change some
16:40
permissions as root on the user's home folder, but nothing I do seems to make
16:40
this message go away.
16:41
as expected all her desktop icons have the "unwriteable" ghostbuster sign on them.

hai
23:55
i have ubuntu installed with ltsp
23:57
i have user authticate through ldap
23:57
all good
23:57
biut user home dir is not created automatically
23:57
why
23:57
what should i have do
23:57
<vagrantc>
your ldap configuration is using pam?
23:58
i.e. libpam-ldap?
23:59
ssh doesn't really play nicely with pam, and the LDM login for ltsp uses ssh.
