Channel log from 23 March 2013   (all times are UTC)

<Enslaver>
booted up and logged in, lemme try it with SERVER=server
00:03
<vagrantc>
SERVER=server ends up with a bunk entry in /etc/hosts
00:05
<Enslaver>
how do we fix that?
00:05* vagrantc tries with SERVER commented out
00:06
<Enslaver>
probably something in 04-server
00:06
in init-ltsp.d
00:08
<vagrantc>
seems to pick the right ip address when unspecified
00:08
<Enslaver>
the server is read from the kernel command line
00:08
ah ok, thats good, so its just not checking for the word 'server' and doing a subsitution
00:09
not like that's needed really
00:09
<vagrantc>
it assumes the server is the root server, unless otherwise specified
00:10
<Enslaver>
can you login to ldm?
00:15
<vagrantc>
finally worked around it ...
00:15
at first i was getting an xterm and then it would crash ...
00:16
so i symlinked ~/.xsession to /usr/bin/icewm-session (the window manager i installed)
00:16
and now it seems to work
00:18
<Enslaver>
ah yah since you installed minimal i bet it didn't find the default WM
00:18
<ogra_>
wow, still with ice as your preferred one ?
00:18
<vagrantc>
ogra_: no, it was just a lightweight one i assumed would be there :)
00:18
<ogra_>
heh
00:18
<vagrantc>
ogra_: i typically use lxde these days ...
00:18
<ogra_>
ah
00:18
i'm on openbox atm ...
00:19
<vagrantc>
the one thing i really don't like about lxde is the lack of useful default keybindings
00:19
<ogra_>
due to the fact that chromium misbehaves here with compositing managers
00:19
<vagrantc>
eesh.
00:19
<ogra_>
well, not chromium, but flash ...
00:19
<vagrantc>
progress!
00:19
<ogra_>
heh
00:20
i'm stealing all the plugins from chromeos :)
00:20
works fine apart from that compositor thing
00:20
<Enslaver>
so should i go ahead and check for iptables in the spec and then throw in a extra rule?
00:20
<ogra_>
++
00:21
<vagrantc>
Enslaver: i guess...
00:21
<Enslaver>
That's definatley gonna trip people up
00:21
<ogra_>
do you disable selinux too as a default ?
00:21* vagrantc wonders if selinux is breaking ldminfod
00:22
<Enslaver>
selinux should be disabled on the client
00:22
<ogra_>
it breaks the world :)
00:22
<vagrantc>
ldminfod runs on the server
00:22
runs fine from the commandline, but not apparently from xinetd
00:23
ah, it's got disable = yes
00:24
that works better!
00:25
<Enslaver>
that's probably why no session
00:25
<vagrantc>
right
00:26
<Enslaver>
ok just updated that
00:26
<vagrantc>
Enslaver: so, regarding the: getent passwd mockbuild
00:26christopher has left IRC (christopher!~christoph@c-174-54-115-236.hsd1.pa.comcast.net, Ping timeout: 272 seconds)
00:26
<vagrantc>
Enslaver: there's no way it will work if the user isn't present
00:26
Enslaver: it needs || something
00:26
or: if getent .. ; then
00:26
<Enslaver>
in the plugin or inside mock?
00:27
because i don't run the userdel from the plugin, mock for whatever reason is doing it
00:27
<vagrantc>
in the 000-mock-chroot plugin
00:27
in the /usr/share/ltsp/plugins/ltsp-build-client/RHEL/009-mock-chroot plugin, to be precise :)
00:27
<Enslaver>
yah thats been updated
00:30
<vagrantc>
Enslaver: in ltsp-trunk?
00:31
<Enslaver>
in my trunk, haven't pushed it yet
00:35
<vagrantc>
got it.
00:37
Enslaver: well, there's some feedback for ya :)
00:38
i don't know when the chroot-setup.d stuff runs, but it seems like most of that should be run from init-ltsp.d
00:38
<Enslaver>
woot, ty =)
00:38
i'm phasing that into init.d, that was ported from warren's code, before there was init-ltsp.d
00:39
not really much left to go, just gonna look it over once more
00:39
<vagrantc>
the session selection seems broken ... even with ldminfod working, it still briefly brings up an xterm and then logs out/crashes
00:39christopher has joined IRC (christopher!~christoph@c-174-54-115-236.hsd1.pa.comcast.net)
00:39
<Enslaver>
ldminfod shows all the ones though?
00:39
<vagrantc>
only way i was able to get a successful session was to symlink the user's ~/.xsession to something
00:39
<Enslaver>
Did you install the one you tried?
00:40
<vagrantc>
or, the default session seems broken
00:41
if you don't specify a session, it fails.
00:42
it fortunately saves the selected session in ~/.dmrc
00:43
and works on subsequent logins without having to specify it
00:43
sbalneav: libpam-sshauth 0.3-1 should be in unstable soonish
00:43
sbalneav: er, debian experimental
00:43
sbalneav: already built for several architectures

<lord4163>
Hello
11:59
Could someone tell me how to boot to LTSP on a wireless laptop? :)
12:00
<ogra_>
by implementing PXE in the WLAN protocols ... talk to WLAN chip manufaturers ...
12:01
(read: it isnt possible ...)
12:03
<lord4163>
orgra_: Yeah well maybe PXE won't work, but maybe I can install some kind of distro on the laptop to boot from there?
12:04
<ogra_>
sure, you can do any kind of local installs ...
12:04
<lord4163>
ogra_: How? :)
12:04
<ogra_>
that wouldnt really be ltsp :)
12:05
by picking a distro and install it ?
12:05
<lord4163>
Yeah but how to connect to the server ?
12:06
<ogra_>
with some kind of remote client
12:07
LTSp is about rempte booting a diskless machine and connect to a server at login time ... find a distro that offers the latter for local installs ... (and make sure your server supports the protocol you use)
12:07
s/rempte/remote/
12:16
<lord4163>
ogra_: I don't care we need a solution to boot our laptops
12:40
<elias_a>
lord4163: There have been some proof of concept solutions on booting over wlan...
12:40
But they are not usable.
12:41Phantomas has left IRC (Phantomas!~Phantomas@ubuntu/member/phantomas, Ping timeout: 252 seconds)
12:41
<lord4163>
Thought my school used something called Novell on there laptops and that booted from PXE?
12:41
<elias_a>
You definately need a lot of bandwith when booting multiple machines. WLAN is not enough.
12:45
<lord4163>
So LTSP isn't what I'm looking for?
12:51
<ogra_>
as i said above
12:51
just install a distro like ubuntu, xubuntu, lubuntu, fedora, SuSE ...
13:06
<lord4163>
Yeah but how do i connect?
13:11
<ogra_>
vnc, rdp, Xforwarding ... there are plenty solutions
13:12
(even proprietary ones for linux like citrix)

<laurense>
somebody know how to fix the 'kernel requires features not present op cpu: pae" error?
17:57
to me it sounds like i ned some other kenrel in my i386 img
17:57
but not sure on which steps to take
18:05komunista has joined IRC (komunista!~slavko@87.244.209.121)
18:13
<vagrantc>
laurense: what distro?
18:14
newer distros may not be possible to use without pae
18:14
<laurense>
hmm
18:14
edubuntu 12.04
18:15
<vagrantc>
installing the -generic kernel should work, i think
18:16
laurense: sudo ltsp-chroot dpkg -l 'linux-image-*'
18:19
<laurense>
alright
18:22
do i need to do anything after that
18:23
<vagrantc>
that just shows what's installed in the chroot ...
18:24
what you probably need to do is: sudo ltsp-chroot -m apt-get install linux-image-generic ; sudo ltsp-update-kernels ; sudo ltsp-update-image ; sudo ltsp-update-kernels
18:25
i threw in a few ltsp-update-kernels for good measure ...
18:26
laurense: but that presumes you have linux-image-generic-pae installed and don't have linux-image-generic installed
18:27
laurense: you might also have to: sudo ltsp-chroot -m apt-get --purge autoremove linux-image-generic-pae
18:27
good luck ... hopefully others can help you with the rest.
18:27
<laurense>
sudo ltsp-chroot chroots me in the ltsp client linux environment?
18:28
then i have an idea what i am doing
18:29
and i think i can get somewhere from there
18:32
hmm
18:32
after the chroot i get an unable to resovle archive.ubuntu.com
18:33
what doesn't help is that my server is amd64
18:34
and all chroot and all update image and chroot image default to amd64, so i need to define i386 with each thing i do
18:34
<vagrantc>
ah, newer versions are smart enough to just pick the only image present...
18:35
good luck...
18:35vagrantc has left IRC (vagrantc!~vagrant@freegeek/vagrantc, Quit: leaving)
18:35
<laurense>
if i can somehow get networking to work in the chrooted environment i would be where i want to be
18:36
probably installing a i386 server instead of amd64
18:37
hmm
18:37
i als could install a small linux install on the thin client and switching to xforwarding after login
18:38
well first looking into getting pxe boot to work

ugh, i have this regexp thats driving me nuts
20:28
im trying to change the line in a file: config_opts['root'] = 'epel-6-i386' to read config_opts['root'] = 'i386' the problem is that epel-6-i386 is a variable

([a-z]+)\-([0-9]+)\-(.*) ?
21:07
Something like that.
21:07
Few less ()'s
21:07
:P
21:07
<lee>
go download a regexbuddy trial
21:07
<Hyperbyte>
Regexps are truely very useful and very horrifying.
21:08
<lee>
and then go buy it when it saves you going bald from tearing your hair out
21:38
<Enslaver>
regexbuddy?
21:39
that yumable?
21:40
<vagrantc>
sed -i -e "s,$SOME_VAR,$YOUR_NEW_VAR,g" ?
21:40
sed -i -e "s,$SOME_VAR,$YOUR_NEW_VAR,g" path/to/file ?
21:40
or only that line?
21:41
<Enslaver>
the first 'root' isnt a variable
21:42
so its hard to match for it
21:42
how do i say change on the first occourance?
21:42
only*
21:44
<lee>
no but it's googleable
21:44
<Enslaver>
n/m it worked
21:44
lee: yeah i found it, windows/wine only
21:47
<lee>
huh
21:47
I would have sworn it was win/mac/linux
21:47
wonder what I'm thinking of
21:49
<Enslaver>
linux and mac using wine :(
21:53
<lee>
it's actually worth runnign wine for
21:53
assuming you a) aren't intimately familiar with regular expressions, b) don't want to be and c) just want to get shit done =)
21:55
<vagrantc>
installing wine seems to miss point c pretty badly.
21:57
<lee>
or boot to windows, whichever
21:57
or run it in a vm
21:58
<Hyperbyte>
:(
21:58
The W-word. :(
