knipwim: good morning, where was that hackathon wiki page? I'd like to add "Drop .nbi support" there...
06:58
Also, could you change http://wiki.ltsp.org/wiki/Meeting:Upcoming to use this instead? date -d '2013/02/25 18:30 UTC'
07:01
<knipwim>
alkisg: http://wiki.ltsp.org/wiki/Dev:Development
07:02
is linked on the homepage

from there you can go to the Hackathon page

Ty, done

Hmm... up to 12.04.1, Ubuntu had a non-pae and a -pae kernel. From 12.04.2/12.10 onwards, there's only the -pae kernel, but it no longer ends in -pae.
08:19
That will confuse our pxelinux.cfg/default generation code... so for 12.04.2 it won't be possible anymore to have both a pae and a non-pae kernel, and let the client automatically decide which one to select

well, my english is very bad, sorry
15:40
I need to save space in a facility edubuntu, I have seen that there is a folder / opt / ltsp, which I guess is to mount a ltsp server, if you do not want to ride-it, I can delete? thanks
15:41
<alkisg>
If you don't use it, you can delete it, yes
15:41
<Hyperbyte>
josepm, /opt/ltsp is for the client. If you don't use LTSP, sure.
15:42
<josepm>
no, i don't use, thanks
15:43
I've uninstalled the LTSP packages, but I left the folder is normal?
15:43
<alkisg>
Yes it's normal
15:43
Delete it
15:44
<josepm>
ok, thank you very much

alkisg: After much googling, I found out that is a reported bug in debian wheezy that nobody have been caring to fix. It was reported in August.
15:47
<alkisg>
engblom: which one?
15:47
<engblom>
Wait, I need to search it up through their bug database...
15:48
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=684008
15:49
<alkisg>
So, downgrading cups solved the problem for you?
15:50
<engblom>
That would probably have been solving too. Instead I edited the ltsp scripts to make /etc/cups permanent on the client and not a tmp-fs folder which is polling the server for printers. Then I copied over the printer configurations. So now all printers also locally installed.
15:51
I hate such hacks.
15:51
<alkisg>
Are those network printers, or connected to the server via usb?
15:52
<engblom>
Network printers...
15:52
So that is why my hack works.
15:52
<alkisg>
Yeah
15:52
I don't think the bug you linked is relevant though
15:53staffencasa has joined IRC (staffencasa!~staffenca@8-220.ptpg.oregonstate.edu)
15:54
<engblom>
At least in Debian Wheezy, it seems to be impossible to get printers shared through cups. The settings in the cups scripts should be right by default, according to the manual.
15:55
<alkisg>
$ cupsctl | grep _share_printers
15:55
_share_printers=0
15:55
That needs to be 1 to share printers, it's 0 by default
15:56
<engblom>
I changed it in my configuration:
15:56
cupsctl | grep _share_printers
15:56
_share_printers=1
15:56
I had been checking up that too...

It is just so typical Debian where "stable" means "can not be changed". Instead of doing like most other (accepting minor updates) they just try with under power to patch themselves.

<knipwim>
Enslaver: i asked about the =~ earlier because we aim to be posix compliant
17:32
<alkisg>
knipwim: what's =~ ?
17:32* alkisg found that posh is good for testing posix compliance
17:34
<knipwim>
apparently a bash and ksh regex evaluation
17:34
<alkisg>
Ah
17:34
<knipwim>
Enslaver: http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/view/head:/common/doc/CodingStyle
17:34* alkisg tries not to use bashisms in scripts
17:35
<knipwim>
not for ltsp at least
17:35
<alkisg>
There's `expr match` if you need it
17:36
<knipwim>
is that faster then piping to grep?
17:38
<alkisg>
It depends on what you want to do....
17:38dead_inside has joined IRC (dead_inside!~dead_insi@66.109.132.74)

17:44
and perl

Hi
17:47
I asked yesterday but without success
17:48
I need to put the chroot in a live usb pen
17:48
and I have a boot script that gets the lts.conf...
17:48
but my live pen isn't working...
17:48
anyone knows how to do it?
17:48
I need a chroot of ubuntu 12.04
17:49
<alkisg>
Enslaver: dash supports it? I don't see it in its man page...
17:49
<Enslaver>
I call dash for my initramfs scripts and use it, it didn't error that i saw
17:49
lemme check
17:50
<alkisg>
lmartins: so you're planning to use an LTSP chroot from a USB stick that connects to a Windows Server? Why would you use LTSP for that, instead of just a custom ubuntu image?
17:51
<lmartins>
Yes...
17:51
<alkisg>
Why?
17:51
<lmartins>
but I want a light image...
17:51
<alkisg>
Why LTSP?
17:52
<lmartins>
I need to have the same behaviour of ltsp but using a live usb
17:52
<alkisg>
Tinycorelinux is 10 mb, isn't that lighter?
17:52
<lmartins>
I only use lts.conf
17:52
yes...
17:52
<knipwim>
Enslaver: well, it doesn't work on posh
17:53
<lmartins>
but I want to have a rdesktop and a ldm session
17:53
<alkisg>
An LDM session to what? An LTSP server?
17:53
Why would you use a USB stick then?
17:53
Why not netboot it?
17:53
<lmartins>
because it's many terminals
17:54
and if they boot at the same time I have a bandwith problem
17:54
if you have any suggestion
17:54
I need something with the same behaviour...
17:54
<alkisg>
And they won't use LDM at the same time?
17:54
<lmartins>
yes
17:55
<alkisg>
You need more bandwidth for a thin client session after login, than for booting it
17:55
OK anyway, to do what you want you need to modify the ltsp initramfs scripts in /usr/share/initramfs-tools
17:55
So that they mount the squashfs image from a stick instead of the network
17:57
<lmartins>
after that I only need to change the filesystem of the usb?
17:57
<alkisg>
Yes
18:00
<Enslaver>
awesome, I'm about to get fired.
18:00
This should be fun
18:00
<alkisg>
Hehe, for using =~ ???!
18:00* alkisg shouldn't joke with such matters though
18:00
<Enslaver>
alkisg: lol, for something just as bad
18:01
i was late for work yesterday, bad me
18:01
<knipwim>
you get fired for that???
18:02
shouldn't be a problem, as long as you finish a days work i guess
18:02
<Enslaver>
yes, in corporate america it doesn't matter how hard you work, it matters that you are there on time
18:02
<knipwim>
keeping your seat warm :)
18:02
<Enslaver>
he's keeping me here until i finish this server, i'm delaying
18:03
He's already contacted red hat to have their team do my job
18:04
<lmartins>
I am the guy with the balancing server
18:04
alkisg do you suggest any other solution?
18:04
I need to boot form live usb
18:05
and then I need to show something on the screen
18:05
<alkisg>
No I don't have any suggestions, I don't know all the details there
18:05
You can do what you want with an initramfs-tools patch
18:05
<lmartins>
and when I plug my smartcard it will run a script to know which server to connect
18:06
<alkisg>
Yup we got that
18:07
<lmartins>
the best way is to change the /usr/share/initramfs-tools?
18:07
<alkisg>
It's one way. Another is to use tinycorelinux. And there are lots of other options. Your call.
18:07
<lmartins>
thank you very much
18:08
ok
18:08
I will see both of them
18:10
do you know which scripts that I have to change?
