07:04	<artista_frustrad> is there a package for student control manager for debian?? if not, where can I get the sources ?
07:06	<sepski> i have heard of a thing called controlaula, not sure if it supports thin clients yet
07:06	<Q-FUNK> hmm
07:07	good question

08:29	timezone on my clients is set to UTC but i'm in UTC+1. is that a known problem?
08:30	interesting. it's supposed to be working. that plugin must be failing.

09:09	<laga> 035-copy-timezone is indeed working, eg it copies /etc/timezone. it looks like /etc/localtime is not updated, though

13:45	<talntid> hi all. I just installed edubuntu and got DHCP working...
13:46	now when I boot the thin client, it doesn't get the file to boot...
13:46	i configured DHCP with webmin... ideas? :)
13:47	<johnny> you prolly shouldn't have, afaik you adjust the one in /etc/ltsp/dhcpd.conf which is prolly not the one webmin edits
13:47	<laga> maybe you should pastebin your dhcpd config
13:47	true
13:47	what he said ;)
13:51	steph_ has quit IRC
13:51	steph_ has joined #ltsp
13:53	<talntid> ok
13:54	actually, it did edit that one
13:54	hold on, the server is on a network with no internet, i'll pastein it though
13:58	http://pastebin.com/m3ecaaab7
13:58	<laga> that looks like the default config
13:58	<talntid> cause i didn't change example.org? :)
13:59	<laga> heh, no because the IP range is still the same :)
13:59	<talntid> it may be near default. the settings work though
13:59	right. those are my optimal settings
13:59	<laga> great
13:59	so, where exactly does it fail to boot?
13:59	<talntid> when the thin client tries to boot.. it says...
14:00	tftp error - file not found
14:01	<laga> what file does it try to download?
14:01	<talntid> no idea
14:01	thats what im trying to figure out too ;)
14:02	don't know where that is configured and all
14:05	no ideas? :)
14:05	i would assume the files in the dhcpd.conf
14:06	which do not exist on my install.
14:07	if i locate the pxelinux.0
14:07	I get 3 different paths
14:07	/opt/ltso/amd64/boot/pxelinux.0
14:07	/opt/ltso/amd64/usr/lib/syslinux/pxelinux.0
14:07	and..
14:08	/var/lib/tftpboot/ltsp/amd64/pxelinux.0
14:08	can't find a nbi.img anywhere
14:09	<johnny> are your clients amd64 ?
14:10	<talntid> negative
14:10	the server is
14:10	<johnny> then having an amd64 chroot won't work
14:10	<talntid> is that a problem? (i know the clients can;t be 64..."
14:10	<johnny> you need ltsp-build-client -a i36
14:10	err i386
14:10	<talntid> invalid option -- a
14:11	<johnny> try --arch ?
14:11	if not.. read the man page
14:11	i don't remember the name otherwise
14:11	<talntid> -- dist maybe?
14:11	same thing?
14:11	<johnny> it's been 4 months
14:11	since i've set mine up
14:12	<talntid> yeah
14:15	Egyptian[Home1 has quit IRC
14:16	Egyptian[Home] has joined #ltsp
14:17	<talntid> it was --arch :)
14:18	<johnny> delete your amd64 dirs
14:18	under /opt/ltsp and /var/lib/tftpboot
14:20	sepski has quit IRC
14:23	subsume has joined #ltsp
14:23	<talntid> done
14:24	setting up internet on the server so it can get the i386 files

15:08	<vagrantc> ok, today's python question ... i just need a fairly basic regex match against a filename ...
15:10	in shell, i've had good luck with: egrep [^0-9a-zA-Z_\-]*$
15:10	the help on the "re" module in python is not particularly informative
15:11	<johnny> how basic?
15:11	<vagrantc> the equivalent of that egrep regex ...
15:12	<johnny> but what are you actually tring to get
15:12	i think there might be a simpler way
15:12	<vagrantc> i have a string, and i want to figure out if it matches the regex.
15:12	<johnny> than using a regex
15:12	tell me what you want the regex to match
15:13	<vagrantc> foo
15:13	<johnny> context please?
15:14	<vagrantc> i'm trying to implement run-parts in python, and want to match it's rules for valid filenames
15:14	the english equivalent to what i'm trying to match is "the names must consist entirely of upper and lower case letters, digits, underscores, and hyphens"
15:15	so i have a list of filenames, and i want to see if each of them matches that rule
15:15	is that sufficient context?
15:15	<warren> why reimplement in python?
15:15	<vagrantc> warren: because some distros don't have a decent run-parts implementation :P
15:16	i'm trying to do this so it's distro-independent ... it can't be that difficult.
15:16	<warren> I mean, is this really necessary given the hack that is in functions now?
15:16	<vagrantc> all i need is to match a filename against a regex
15:17	warren: i'm trying to implement it in ltspfsmounter, which is written in python
15:17	warren: so a shell function isn't particularly useful.
15:17	<warren> oh
15:17	<vagrantc> regex in python is so absolutely alien to me.
15:18	ah, ok... i think i've found what i need
15:19	hrm... gah this is complicated.
15:20	there's got to be a simpler regex library for python
15:23	ok, i'm getting the swing of it ...
15:29	or not
15:32	x=re.compile('^[a-zA-z0-9]+')
15:32	what i don't understand, is why x.match('foo.bar') ... matches
15:34	match is only the beginning of a string
15:35	maybe the ^ is not needed then...
15:42	ah ...
15:43	x=re.compile('^[a-zA-z0-9]*$')
15:44	don't know if i should use * or +
15:57	Q-FUNK has quit IRC
16:02	achandrashekar has quit IRC
16:04	<vagrantc> got it.
16:04	well, still unsure on * or + ... both seem to behave properly.
16:05	i think * ... as someone could actually include a file that's only a single character ...
16:14	<johnny> does fnmatch not do enough?
16:14	* vagrantc wasn't aware of fnmatch
16:15	<vagrantc> johnny: i've gotten it working with re.compile ... but if you've got something better, by all means ...
16:16	johnny: you're acting as though i have a clue with python :P
16:17	<johnny> oh.. well the thing is
16:17	i don't
16:17	i'm just guessing
16:17	i'm still learning python myself
16:17	<vagrantc> having no idea what fnmatch is, where it's from, etc., i cannot compare it to re :)
16:18	<johnny> web search python fnmatch ?
16:18	http://docs.python.org/lib/module-fnmatch.html
16:18	i'm heading down to where my ltsp install is, i'll be back online in 20
16:19	<vagrantc> oh, that looks much simpler.
16:21	actually, too simple ...
16:22	doesn't seem to support ^ or $ ... or "any number of additional matches"
16:24	i'll stick with "re" ... it wasn't too bad ... just frustrating to figure out how it worked.
16:24	Egyptian[Home] has quit IRC
16:42	johnny_ has joined #ltsp
16:44	<johnny_> sup vagrantc did i miss anything?
16:48	<vagrantc> johnny: other than: 14:24 -!- Egyptian[Home] [n=Egyptian@62.117.54.251] has quit [Connection timed out]
16:49	absolutely nothing
16:49	although, seconds ago i re-worked the patch i had to add icons on the KDE desktop to be used with the new ltspfs hooks i implemented last night
16:49	<johnny_> eword
16:50	so did fnmatch work for you?
16:50	<vagrantc> johnny: no, it was missing things like ^ and $ for beginning and end of line, as well as "match any number of FOO"
16:52	"re" is working for me.
16:53	just was really confusing as to how to use it, at first.
16:55	<johnny_> word
16:55	hmm.. i should really follow what you guys are doing outside of here
16:56	<vagrantc> klausade: so, i just re-worked your patch for KDE desktop icons to work with ltspfs's hook system that i just wrote.
17:01	klausade: hope to include it in a new upload soon.

17:48	its downloading the whole internet. :)
17:54	<vagrantc> you can set how much of the internet it downloads with --internet-percentage
17:56	<laga> for a minute i was going to check --extra-help...

18:18	anyone have first hand knowledge of installing x11vnc on the thin clients so i can look at them via the thin client manager?
18:19	looking at a tutorial, but it seems to be made for people who are using a 386 server :)
