<johnny>
you do not use ltsp-manager in any ubuntu since dapper i think
00:15
err no.. maybe feisty
00:15
Chikubu, that is to you
00:17
<Chikubu>
ok
00:17
im a bit lost
00:18
i keep seeing refernces to /opt/ltsp but that directory doesnt exsist, i think im missing a step were i populate that diretory, maybe using chroot and copying files to it
00:18
i havent grasped the top view of the process yet
00:21
anyone enlighten me a bit, i have a dhcp server, i think i have it set up correclty it refrences /ltsp/i386/pxelinux.0 and /ltsp/i386/nbi.img those directories dont exist, what must i do to create them
00:21
i want this machine to allow another machine to boot from it over the netwrok
00:22
<johnny>
you have to use ltsp-build-client
00:22
and.. if your server is amd64 and you want i386 clients, you must use --arch=i386
00:22
at least currently
00:23
it may default to 32bits on a 64bit machine due to the common usage of that
00:23
<Chikubu>
its a 32 bit cpu
00:23
<johnny>
ok
00:23
then ltsp-build-client is enough
00:24
<Chikubu>
which folder to i run ltsp-build-client from or does it matter
00:26
its giving alot of errors
00:36
are these warnings serious? job-working-directory: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
00:41
not giving those now nm
00:57
<johnny>
you do have to make sure your machine has openssh-server installed
00:58
<Chikubu>
thanks it does, the build wants to download, im trying to figure how to divert it to an offline source now

Hello all! Anyone have a favorite thin client hardware device that can do dual-head? I am looking to move some developer workstations over to LTSP and we really like our two big monitors.

Hi evey1
09:12
how is it going?
09:12
Is there anyway to each time an user logout the home folder is restored to its initial state???
09:12
its for the use in an public machine, like a kiosk terminal
09:13
i guess i can create a script that creates the backup image of the public user account
09:13
and then write a boot script that restores the backup image of the public user account
09:13
am i in the right direction???

I want to install Ubuntu intrepid in a school server, *to be used at autumn*. Which is the best road? Install 8.04 now and upgrade to 8.10 in October, or install 8.10 alpha now and only install the updates later? I'd prefer 8.10 if there won't be any problems with updating directly from alpha to final...

11:42
<Jane_ux>
how can i execute an script when an ltsp user logout??
11:42
or login
11:49
<Nubae>
login would be ./bashrc
11:50
<Jane_ux>
ok thanks
11:50
but where bashrc is located???
11:51
<Nubae>
home folder
11:51
sorry... /home/user/.bashrc
11:51
<Jane_ux>
ok thanks
11:51
u know
11:52
the thing is, I wanna restore the home folder of the user each time he login or logout
11:52
so it is possible by placing the script in .bashrc??
11:53Ronin1234 has quit IRC
11:53RoninBaka has joined #ltsp
11:53
<Jane_ux>
or the init.d is executed each time a terminal starts??
11:54
<Nubae>
first, what OS
11:54
<Jane_ux>
ubuntu
11:54
<Nubae>
ok, what I'd do is put in lts.conf
11:54
rcfile01=/path/to/script/
11:54
hmm but that will do it on startup... not on login...
11:55
<Jane_ux>
its ok, anyway on login???
11:55
<Nubae>
well yeah .bashrc should do it
11:55
<Jane_ux>
but when a terminal startup i guess... not when the server start up isnt it??
11:56
<Nubae>
wehn a user logs in bash is always invoked
11:56
its an ssh -X session
11:56
<Jane_ux>
yep
11:56
<Nubae>
so try that
11:56
<Jane_ux>
ok, addin it to /home/user/.bashrc
11:56
?
11:57
<Nubae>
yes... user being the user for who the script should startup
11:57
<Jane_ux>
ok i ll try that, thanks very much
11:58joebaker has quit IRC
11:59
<Nubae>
also
11:59
for logout its: .bash_logout
12:00
also in the home folder
12:00
<Jane_ux>
ok
12:00
<Nubae>
let me know how that works for u k?
12:01
<Jane_ux>
the script is "cd /home" "tar xvfz /home/restore_user.tar.gz"
12:01joebaker has joined #ltsp
12:01
<Jane_ux>
i just add it into the end of .bashrc isnt it??
12:01
ok i let u know... :)
12:02
<Nubae>
yep
12:03
you could also add it to /etc/profile
12:03
and that would be system wide
12:04
ie... for every user
12:05
<Jane_ux>
ok, nice to know it
12:05
and I dont need to upload the ltsp image isnt it???
12:05
<Nubae>
update? no...
12:05
this is server side
12:07
<Jane_ux>
nope
12:07
doent work
12:07
<Nubae>
doesn't work?
12:07
ok... then try it this way
12:07
<Jane_ux>
i added
12:07
cd /home
12:07
tar xvfz /home/restore_test.tar.gz
12:07
to .bashrc
12:08
and yep restore_test.tar.gz exist n workin fine
12:09
ok tell me which way
12:10
<Nubae>
make a file called .xsession
12:10
in /home/$user
12:10
make sure its executable too
12:10
<Jane_ux>
as root??
12:10
<Nubae>
using sudo, sure
12:10Q-FUNK has joined #ltsp
12:11
<Jane_ux>
in the file i just put the script code??
12:12Q-FUNK has quit IRC
12:12
<Nubae>
yeah, try it
12:13
<Jane_ux>
ok done, and executable
12:13
<Nubae>
Otherwise do it the GUI way... System ->
12:13
Preferences -> Sessions menu.
12:14
<Jane_ux>
yep
12:14
command: /home/user/.xsession isnt it???
12:15
<Nubae>
thats where u put the script yes
12:15
for logout... the gdm way is like this: /etc/gdm/PostSession/Default
12:15
and in that file put the following:
12:15
logoutscript="$HOME/.gdmlogout"; if [ -x "$logoutscript" ] ; then su $USER -c "$logoutscript" fi
12:16
and make a file called .gdmlogout and put in there whatever it is you want to happen
12:16
put the file in the users home dir
12:16
<Jane_ux>
ooopsss
12:16
it doesnt login
12:17
blank screen and then come back to login window
12:18
<Nubae>
hmmm... and what did u put in your .xsession?
12:18
<Jane_ux>
the thing is im tryin to restore the home folder, anything with that??
12:19
<Nubae>
resetore?
12:19
<Jane_ux>
i put
12:19
cd /home
12:19
tar xvfz /home/restore_test.tar.gz
12:19
<Nubae>
that could cause conflicts yeah
12:19
<Jane_ux>
ooook
12:19
<Nubae>
because you are already in the home folder
12:19
try with a simpler script
12:20
try executing gedit or something
12:20
<Jane_ux>
yep simpler script work nice
12:20
but i wanna restore the home folder in login
12:20
or logout
12:20
it is possible??
12:20
<Nubae>
logout might be easier
12:20
try it
12:20
<Jane_ux>
ok
12:21
<Nubae>
u want a clean environment for every login I guess?
12:21
<Jane_ux>
yep
12:21
<Nubae>
y dont u use lockdown editor instead then?
12:21
and have a script that cleans up after the user logs out
12:22
<Jane_ux>
lockdown editor?? like pessulus??
12:22Ronin1234 has joined #ltsp
12:22RoninBaka has quit IRC
12:22
<Jane_ux>
script that cleans up?? like restore the home folder?
12:27
nubaeeee??!!
12:30
are you there???
12:30
logout script doesnt work
12:38Nubae has quit IRC
12:40Nubae has joined #ltsp
12:40
<Nubae>
hmmm did my connection just go?
12:44
<Jane_ux>
heyyy
12:44
did u say: script that cleans up... any idea
12:44
<Nubae>
did u get all that I wrote?
12:44
<Jane_ux>
nop
12:44
im afraid
12:44
<Nubae>
(07:29:41 PM) Nubae: hmmm anyway script is here: https://wiki.edubuntu.org/EdubuntuResetDesktopSession
12:45
you'll probably need to edit it a bit
12:45
but the foundations are good
12:45
<Jane_ux>
ok, im avin a look
12:45
and the logout script didnt work
12:46
maybe because im trying to restore the home folder????
12:46
<Nubae>
yeah I don't think that would work
12:46
u'll need to either lockdown or clean up after user
12:46joebaker has quit IRC
12:46
<Nubae>
or.... unmount /home
12:46
restore, then mount
12:47
maybe...
12:47
<Jane_ux>
ok
12:49
about the clean up, dont u think is better to restore the /home folder completely???
12:49
<Nubae>
if it were easy, then sure... but its not going to be...
12:50
<Jane_ux>
i guess not
12:50
ahhh and thanks very much in advance
12:50
:)
12:50
ok umount /home dont work neither
12:50
<Nubae>
yeah no problem, if u get a nice working script, be sure to put it up on a wiki somewhere
12:51
<Jane_ux>
of course
12:51
i ll refer u aswell
12:51
<Nubae>
I'd study the script that was on that page
12:51
<Jane_ux>
ok
12:51
i know its possible to put d script in d init.d in the server
12:51
<Nubae>
if they are doing it that way, then the restore way probably isn't possible ;-)
12:51
unless u do it on startup of client
12:51
<Jane_ux>
and then restart the server every night
12:52
<Nubae>
right
12:52
u can do ti by putting it in lts.conf too
12:52
<Jane_ux>
not to bad, but would be better in the way u told me
12:52
at login or logout
12:52
yep
12:52
<Nubae>
using the 2 methods might be the best solution... on startup of client...
12:53
and cleanup using the script on logout
12:53
<Jane_ux>
yep
12:53
<Nubae>
should be good enough... are u running an internet cafe or school or what?
12:53
<Jane_ux>
any idea how the script can be in logout
12:53
its for my school
12:53
<Nubae>
the way I mentioned above
12:53
<Jane_ux>
thoun now just for pure researsh and fun
12:53
<Nubae>
or did u test a simple script that way already?
12:54
<Jane_ux>
nop really
12:54
<Nubae>
ok try something like touching a file or something (touch example.txt)
12:54
and then see if the file exists when u login again

12:56alkis1 has joined #ltsp
12:56johnny has joined #ltsp
12:56
<Jane_ux>
touch /home/test/example.txt not working
12:56
is this ok "logoutscript="$HOME/.gdmlogout"; if [ -x "$logoutscript" ] ; then su $USER -c "$logoutscript" fi"?
12:58alkisg has quit IRC
12:59
<Jane_ux>
ok, anyway, i ll do it in the init.d way and restart the server every night
13:03
<Nubae>
should be on seperate lines
13:05
try putting the script directly in /etc/X11/gdm/PostSession/Default.
13:05
that will be for all users, but in your case thats fine
