<muppis>
Have anyone tried build client without LDM?
00:31
Like just having X and some program to run on it locally.
01:32
<sep>
that's the diskless workstation mode, i'd say it's fairly common
01:33
<muppis>
So it should be easy to set up ?

sep: "fatclients" :: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
01:34
<muppis>
I think need little adaption here..
01:35
<sep>
what do have it on ?
01:36
<muppis>
I got some time ago local installation from mini.iso with X, pulseaudio and xbmc. Like that to be loaded as thin client is.
01:47
<sep>
i usualy do that as a stright off nfs root + pxe boot.
01:47
no need for ltsp for 1 device

This is more a PulseAudio question than an LTSP question, but I hope someone can tell me anyways..... :-)
05:18
I run sflphone (voip softphone) as a local app, but it's using the onboard soundcard instead of the USB headset I plugged in
05:19
How can I configure the thin client to use the USB headset by default? Is there some command I can run at boot to tell pulseaudio to use the USB headset for playback/recording?
05:19alkisg has quit IRC
05:21
<muppis>
Do you use onboard anywhere?
05:34
<Hyperbyte>
Nope
05:34
But I would kinda like it to be plug&play... like... as soon as a USB headset is plugged in, stop using onboard and switch to that
05:34
<muppis>
Then you should be fine if you disable it from BIOS?
05:35
<Hyperbyte>
So disabling it from BIOS isn't really what I'm looking for
05:37
<muppis>
HMm.. I know, but that would be easiest.
05:39
<Hyperbyte>
But not really suitable, because some people use USB headsets, others don't. =)
05:39
<muppis>
That changes the case.

Kyle__: Hey Kyle, I've got a question on your Virtualbox ltsp setup, if you have a minute
11:31
Anyone know of a way I can start a local program on boot? Perhaps in a second screen, so my users can just alt+whatever and have it up and going?
11:31
<alkisg>
Make a screen script and put it in SCREEN_08=your_script in lts.conf
11:31
An example: https://help.ubuntu.com/community/UbuntuLTSP/GParted

Hi guys, I'm facing small problem while logging in a dumb ltsp terminal, daemon.log on server says nbd-server "Disconnect request received." , my image size is 540 mB and hence I think the nbd server is giving error.. how can I resolve this ?

i tried setting up gconf keys to disable the screen locker, but it spits out a bunch of messages about wanting a boolean value and getting a string
13:16
i specified: /apps/gnome-screensaver/idle_activation_enabled TRUE
13:17
is it case-sensitive/specific?
13:18

U joined in after I asked the question :( No one else yet replied but Im waiting :)
13:19
<vagrantc>
distro and release?
13:20

ubuntu?
13:20
<Trixboxer>
yup
13:20
<abeehc>
ltsp.pastebin.com the actual log file
13:20
are your clients not working?
13:21
<Trixboxer>
http://ltsp.pastebin.com/bf50unrd
13:21
they are able to boot up but the error comes when I try to log in the ltsp client
13:21
I read that its due to size of img file
13:21
<abeehc>
I don't think that's your problem i could be mistaken
13:22
i thought those errors were benign
13:22
so you can't login?
13:22
<Trixboxer>
nope
13:22
<abeehc>
/var/log/ldm.log might be most interesting
13:22
<Trixboxer>
I created 2 users by chrooting in client environment
13:22
<abeehc>
you don't logon as a user int he chroot environnment
13:23
as far as i know anyway
13:23
you login as a user the server knows
13:23
<vagrantc>
Trixboxer: what do you mean by "dumb ltsp terminal"?
13:23
<Trixboxer>
no such file.. may be I dint enabled loging
13:23
vagrantc: LTSP client.. Im a newbie to LTS{
13:23
LTSP*
13:24
<vagrantc>
Trixboxer: graphical login, or text login?
13:24
<Trixboxer>
graphical
13:24
<vagrantc>
then you shouldn't create users in the chroot.
13:24
use users added on the server.
13:24
and disable the users in the chroot.

ok trying
13:26
vagrantc: Still the same log
13:26
I added a user on server
13:26
<abeehc>
wrong log to start with
13:27
<Trixboxer>
abeehc: ldm.log file not present
13:27
<abeehc>
that's rough
13:28
<vagrantc>
ldm.log wouldn't be present on the server
13:28
it would be on the thin client ...
13:28
<abeehc>
i don't mean on the server, definitely lok on the client
13:28
<Trixboxer>
shall I install ldm ldm-server ?

13:28
<abeehc>
how did you install this in the first place, Trixboxer
13:28
some instructions?
13:29
it's a miracle your even getting a login screen hah
13:29
<Trixboxer>
haha
13:29
<abeehc>
:) at least many people come in not even able to get that far
13:29
<Trixboxer>
http://wiki.debian.org/LTSP/Howto
13:30
<abeehc>
a common problem is shs keys maybe just for a quick shot do ltsp-update-sshkeys on the server
13:30
then ltsp-update-image
13:30
don't use those instructions though
13:31
<Trixboxer>
hmm tried that as well
13:31
<abeehc>
https://help.ubuntu.com/community/UbuntuLTSP
13:31
use these
13:31
<vagrantc>
Trixboxer: that's for debian ...
13:31
<abeehc>
i think even if you were using deb use the ubunutu wiki hehe
13:31
<Trixboxer>
k checking it
13:31
<abeehc>
are you certain there's no ldm.log on the clients?
13:31
<Trixboxer>
do I need to restart anything after ltsp-update-image
13:32
yes
13:32
no such file
13:35ogra_ac has quit IRC
13:39sweetpi has joined #ltsp

reboot the clients once you run ltsp-update-image

https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/530044 :(
13:46
<Hyperbyte>
ldm.log only appears when you enable LDM_DEBUG in lts.conf
13:46
<vagrantc>
abeehc: the ubuntu wiki uses a lot of ubuntu-specific instructions that would cause problems on debian.
13:46
abeehc: *please* don't recommend that to people.
13:47
<Hyperbyte>
So make sure LDM_DEBUG=True is specified in /var/lib/tftpboot/ltsp/i386/lts.conf (if memory serves)
13:48
<abeehc>
deb instructions look ugly
13:48
<Hyperbyte>
You can also put SCREEN_05=shell.. if you then press ctrl+alt+F5 on the thin client you get a root prompt on the actual client (regardless if you have logged in)... it's good for debugging purposes, like reading the ldm.log on the client
13:49
<vagrantc>
abeehc: maybe sometimes debian looks ugly, but it works.
13:49
<Hyperbyte>
^^ that was all for Trixboxer
13:51
<abeehc>
vagrantc: i've used it longer than i've used ubuntu of course
13:52
for me it's far from ugly; those instuctions aren't awesome though
13:52
i thinki it might have started working for Trixboxer
13:52dlezcano has quit IRC
13:52
<vagrantc>
well, it does happen to be a wiki... i.e. it is editable
13:52
abeehc: if you see how it could be improved, do so
13:53
<abeehc>
thanks for the pro tip

<_UsUrPeR_>
a quick question about SIP network traffic. I am having some echo/jitter problems. Can I bend someone's ear?
14:08
These echo/jitter problems have only recently cropped up at the installation we are at, and it's confusing me. The SIP network we are running is dedicated. There is only one switch, completely independent from the rest of the internal network
14:08
this was done so that we would not have to screw around with QOS
14:09
also, there is a concern pertaining to the security of the internal network as well
14:10
We are running a nice 8-core Xeon 1U ProLiant system. It has a single 4-port gigabit NIC on the rear, and that is connected to a Dell 48-port POE switch
14:10
all gigabit
14:10
during heavy call volumes, we have been hearing reports of jitter and echo
14:10
all spurious, none can be nailed down to a certain network drop
14:10
<abeehc>
i think you are in the wrong channel
14:10
wireshark is useful for that, though
14:10
<_UsUrPeR_>

14:30
i get so spoiled by LTSP's sloppy booleans :)
14:30
<alkisg>
vagrantc: if you're using a package, it should be called automatically
14:30
(with debian/package.gconf-defaults)
14:31
<vagrantc>
alkisg: yeah, but before uploading a new package, i wanted to have some verification that it actually worked :)
14:31
<alkisg>
Ah, I just use debuild locally for that :D
14:33
True / true / TRUE, all valid in *some* programming languages... easy to get confused...
14:33
<vagrantc>
i test the installs on other machines
14:33
so i have a separate build environment from my test environment
14:33
<stgraber>
yeah, it's case sensitive ... I had to fix edubuntu's gconf defaults once because every software using gconf would complain (on stderr) about "true" not having the right casing ;)
14:34
<vagrantc>
ouch
14:35
so it didn't used to be case sensitive or something?
14:36dlezcano has quit IRC
14:36
<stgraber>
or I just never noticed the error :) the software would still work fine, it was just complaining
14:37
<Kyle__>
I get offended by case-insensitivity.
14:37
constants are UPPERCASE, variables are lowercase.... I like that.
14:38
<Ghidorah>
Does anyone know if in LTSP-Cluster can you use 32bit app servers?
14:38* vagrantc gets teared up over case insensitivity
14:39
<Kyle__>
Ghidorah: Um, you can use 32bit app servers in standard LTSP and in LTSP fat clients.. so I don't see why not...
14:39
<Ghidorah>
blah my question made no sense... Can you use 32bit app servers when the root server is 64 bit?
14:39* Kyle__ has enver used LTSP cluster however.
14:39
<Kyle__>
Ghidorah: You can do that as well with LTSP-fat clients, so again :) I don't see why not.
14:39
<Ghidorah>
Thank you Kyle

stgraber: it definitely didn't actually work for me ... i tried disabling screen locking and then came upon a locked screen ... here's to walking away from projects and getting distracted by other things :)

Good day. I hope everyone is well. Just installed Ubuntu 10.10 after our Fedora server decided to give up the ghost suddenly. Was wrestling with it yesterday and I'm wondering if what I'm seeing is normal function: An HP laserJet parallel printer connected to a thin client only works if I include SCREEN_02 = shell. Otherwise it won't print. Normal?

<TheProf>
Hmm...Probably too wordy of a question. Let me re-phrase: I can't print unless I include screen_02=shell in lts.conf. Normal? :)
18:38
<vagrantc>
TheProf: simply including it makes it work?
18:38
<TheProf>
vagrantc: Yes. It was like a toggle. Add it, printing works. Comment it out, printing fails.
18:38
<vagrantc>
that's weird.
18:38
i don't see how that could happen, but i've seen stranger
18:39
<TheProf>
It's not really a bad thing - I just include screen_07=ldm to get the graphical login so the computer can still be used and it works fine.
18:39
I just was worried that it was a symptom of something worse?
