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

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.

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

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 ;)
13:51steph_ has quit IRC
13:51steph_ 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

<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 +
15:57Q-FUNK has quit IRC
16:02achandrashekar 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.

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.

you can set how much of the internet it downloads with --internet-percentage
