<bennabiy>
Does anyone know where the actual call is that generates the client side pulseaudio --system <long list of parameters> comes from?
00:07
ubuntu 13.04
00:10
vagrantc: Do you know where the actual pulseaudio system call is to start the client side server?
00:14
<vagrantc>
i don't use ubuntu
00:16
bennabiy: but it might call the start_sound function from <chroot>/usr/share/ltsp/ltsp-init-common
00:16
bennabiy: it uses a different init system from debian... no idea if it calls the /etc/init.d/ltsp-client* init scripts.
00:17
<bennabiy>
I dug through the sound functions there, but did not see any reference to the system call, although I can look again. I am sure it is somewhat similar to the debian call
00:18* bennabiy is getting closer to the bug... SQUISH!
00:18
<vagrantc>
looks like it does call start_sound from the upstart location
00:18
i think in /etc/init
00:18
<bennabiy>
so ltsp-init-common would be the place where the arguments are added to the call?
00:19
where start_sound is?
00:20
<vagrantc>
the /etc/init/ltsp-client-core.conf upstart hook calls the start_sound function
00:20
<bennabiy>
ok. I will check that next
00:20
<vagrantc>
which comes from ltsp-init-common
00:20
it should really be moved to udev...
00:20
<bennabiy>
that is what I thought
00:20
I dug all through udev for it
00:20
<vagrantc>
since there are usb sound devices
00:21
but that's not yet implemented
00:21
<bennabiy>
bah, what do those developers think they are doing anyways? ;)
00:21
I really appreciate you help vagrantc.
00:21
<vagrantc>
i needed to add
00:22
>
00:22
"> -L module-suspend-on-idle \"
00:22
er...
00:22
<bennabiy>
wrong channel?
00:22
<vagrantc>
bennabiy: there was a thread on ltsp-discuss@lists.sourceforge.net that fixed sound for me on debian wheezy
00:22
Subject: Re: [Ltsp-discuss] Debian 7 LTSP Pulseaudio possible fixes
00:22
<bennabiy>
hrm... when was that?
00:23
is it on gmane?
00:23
<vagrantc>
late june, my reply was late july
00:23
<bennabiy>
I just posted to ltsp-discuss
00:25
<vagrantc>
https://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/revision/2483/client/initscripts/ltsp-init-common
00:26
<bennabiy>
I found the post, on ltsp-discuss
00:26
<vagrantc>
sure. that's just a link to the code committed
00:27
<bennabiy>
I see that. who is handling the ubuntu or mint dev?
00:27
Let me see if it works. I have Ford_Prefect waiting on some logs from me in the morning about the issue in #pulseaudio
00:28
I want to crash it in logs first, before I fix it... although I am sure I can break it and log it if I need
00:29
<vagrantc>
no mint developers, as far as i know... there's not one line of code in upstream ltsp
00:30
handful of people in here who work on ubuntu
00:34
bennabiy: good luck
00:34* vagrantc waves

Hello!
01:36
<TheUser>
how does this work with rdp clients
01:37
?
01:41
I dont need all the thin netbooting stuff
01:43
but i do need something that will work with the pile or cheap RDP clients i have
01:45
<bennabiy>
What exactly are your RDP clients?
01:45
<TheUser>
cheap little chinese things about the size of a cigarette pack
01:47
Work great with the virtualbox rdp stuff
01:54
<bennabiy>
hmm, not sure what to tell ya

Question to the devs here: The Xsession that get's started from a chroot when a thin client boots, where are the config files for it? Are they the ones in the chroot or the ones in /etc/X11 on the server?
09:06
TheUser: Maybe you should look into X2Go. There you can connect to a Linux server using a number of clients and as far as I know, RDP is one of them
09:07
On the other hand, can you trash the RDP on this clients? Or ignore it? If you can pxe boot, then it will probably work fine with LTSP

any hints on how to debug that damn script are appreciated
16:49
<||cw>
the brute force way is to have it write messages to a file in /tmp
16:49
<moldy>
||cw: you mean stdout/stderr?
16:50

or just echo "x is $x" >> /tmp/debug.txt

why doesn't the damn thing just abort immediately on error :-/
16:59
<Hyperbyte>
moldy, does /var/lib/tftpboot/ or /srv/tftp exist?
16:59
Also, which distro/version is this on?

Hyperbyte: ubuntu 12.04. both exist
17:09
the os was updated from 10.04, which didn't run smoothly
17:09
(the update, that is)
17:10
<||cw>
I'm not sure I'd try that as an in-place update
17:11
<moldy>
you mean i should reinstall?
17:11
hehe, it's supposed to be a "supported" update
17:11
<||cw>
copy off the /home and rebuild the OS. or at least rebuild the ltsp config from scrtach
17:12
there's a lot of changes to ltsp between those, and it's note widely used enough for anyone to claim that it's a stable well supported in-lace upgrade
17:12
there's like'y 5-10 people world wide that do it.

sounds legit. I haven't tried that upgrade yet. dreading it, actually.
17:30
<moldy>
after the distribution upgrade, i was missing some essential packages, but that was easy to figure out
17:37
a grep for "error" in the script's output finds nothing of interest
17:47
tried to just run ltsp-update-image and boot a client. seems to work at first, but my clients need a different kernel (no pae support)
17:51
<bennabiy>
Hey vagrantc, I fixed my audio
17:51
it was the same thing you had to do
17:51
I issued a bug report, if someone who can commit the change can fix it
17:53
<moldy>
stgraber: looking at 020-kernel-selection, it seems that ltsp prefers pae over non-pae (5.3.7-0ubuntu2) -- is that a bug?

bennabiy: thanks!
18:09
bennabiy: in the future, submit patches using "diff -u old-file new-file"
18:09
but since it's already committed upstream, that shouldn't be an issue.
18:09* bennabiy is only used to fixing my local system... the whole cvs thing still gets me

cvs? heh :)

vagrantc: I will do that
18:10
I mean, upstream, downstream, whitewater etc ;)
18:12
<vagrantc>
hopefully with ltsp6 we can just run the daemon as the user or something ... actually, might not be too terribly difficult too get ldm to do that now.
18:12
using localapps or something ... dunno
18:34
<moldy>
hm, it seems that the client environment does basically work
18:34
maybe something is just returning non-zero here and confusing ltsp-build-client?
18:38
<bennabiy>
I am not sure if the proper devs are in here for this, but this is an observation I had about the sound issue.
18:41
Once audacity clobbered the sound, even without adding the " -L module-suspend-on-idle \ " if on the client I manually killed the pulse session, and then made a simple bash script to reference ltsp-init-common and call start_sound it worked fine and audacity and vlc and whatever could all play together find
18:41
s/find/fine
18:44
It made me think that whenever the call is being made to start_sound during the login, the permissions are getting clobbered or something after it
18:52* bennabiy hears crickets...

Anyone that has experience with Xsession errors when logging into LTSP? vagrantc? stgraber? sbalneav? sunweaver? Anyone else? Dunno if any of you have time to read the detail, but I have posted the details in http://www.mail-archive.com/ltsp-discuss@lists.sourceforge.net/msg41373.html, but I'm totally stuck. All I can do is delete the user's profile and start again, but then I don't know what causes this. Don't want to really do

Hi. I'm trying to run ltsp-build-client on Centos 6.4 from behind an authenticated proxy but it can't connect to mirrorlist.centos.org.
21:39
Can someone please tell me how to tell ltsp-build-client to use my proxy?
21:44
<||cw>
Random_: I don't know if there's a standard way to do that. you might have to ask whoever ported it to centos/yum
21:44
at my work we got tired of that crap and whitelisted the various OS update sites for things we want to update automatically
21:45
<dead_inside>
Random_: when your in the chroot can you try executing the same commands you used on the server to connect it to the proxy?
21:45
<||cw>
for deb based stuff, even went as far as install apt-cacher-ng so systems don't need the web proxy at all
21:46
dead_inside: ltsp-build-client is what creates the chroot
21:46
<dead_inside>
can your server connect online? like the ltsp stuff aside
21:46
<Random_>
Is there somewhere I can put an export http_proxy command in the chroot envornment?
21:47
I have http_proxy set in my environment, but it doesn't get used when the chroot happens.

there appears to be a --http-proxy option
21:49
<vagrantc>
Random_: are you using sudo? it may clean out "hazardous" environment variables
21:50
<Random_>
Not in the version I am running.
21:50
Don't shoot me, but I'm logged in as root.
21:50
<vagrantc>
--http-proxy only exists for Debian variants
21:51
<Random_>
Bummer
21:51
<vagrantc>
it shouldn't be hard to implement...
21:51
but if it's not respecting your already set environment variable...
21:51
<Random_>
Is there a config file that sets the environment for the chroot?
21:51
<vagrantc>
there may be bugs in software ltsp-build-client is calling that cause the problem
21:52
Random_: you could create /etc/ltsp/ltsp-build-client.conf and add: "export http_proxy=..."
21:53
that *should* work across all distros
21:53
but if it's not respecting the settings in your environment, then it's probably some tool that ltsp-build-client is calling that's not respecting it.

Just tried that. No change.
21:55
I might just have to bypass the proxy and allow the server direct access to the Internet.
23:14
Success at last. I allowed the server through the firewall and now ltsp-build-client has completed. Thanks for all your help.
