hi
02:05
<elias_a>
alkisg: thanks for keeping up the pressure on Adobe Flash player and FP-40 bug :)
02:05
<alkisg>
elias_a: are you still affected by it?
02:06
It's pretty much ok for me now, except for the accented characters... (which are important...)
02:06
<elias_a>
alkisg: Not to my knowledge....
02:06
But I have not done a thorough test.
02:07
<alkisg>
I do hope that it gets out of beta in time for lucid ... :-/
02:07
<elias_a>
We have some probs with some services. We used a workaround in OpenMeetings and now the workaround causes problems when the bug is fixed :(

alkisg: ping
03:32
<alkisg>
hi nubae
03:32
<nubae>
good morning...
03:32
I'm just looking through my config files again to see whats up with my nbd connection refused errors
03:33
I noticed that my dhcpd.conf has /ltsp/i386/nbi.img and not /opt/ltsp/i386/nbi.img... is that correct?
03:33
<alkisg>
That's relative to the tftpbootdir
03:34
/var/lib/tftpboot - /ltsp/i386/nbd.img
03:34
<nubae>
hmm, yeah so its correct
03:34
I've got my router as 192.168.1.1 which is my internet router and ltsp/dhcp server as 192.168.1.128
03:35
maybe there is an issue of being on the same subnet?
03:36
<alkisg>
You said yesterday that you succeeded in manually calling nbd-client
03:36
So I guess it's a race problem
03:36
<nubae>
yeah I did
03:36
<alkisg>
Just change ltsp_nbd so that it has a sleep there, or so that it calls nbd-client twice if it fails the first time
03:37
Are you using the stock ltsp or some newer version from a repo?
03:37
<nubae>
nope its stock karmic
03:38
<alkisg>
Yup then try with a sleep or calling it twice
03:38
<nubae>
ltsp_nbd in hooks or scripts dir?
03:38
<alkisg>
scripts
03:39
<nubae>
sleep at the top?
03:40
<alkisg>
right before the nbd-client call
03:40
then update-initramfs -u at the chroot, and ltsp-update-kernels
03:40
put a sleep 5 just to be safe...
03:41Egyptian[Home] has quit IRC
03:41pts_ has quit IRC
03:45pts_ has joined #ltsp
03:45
<nubae>
yeah that didnt work, seems like its looking for nbd-server at 192.168.1.1
03:47
I've got nextserver defined as 192.168.1.128 in dhcpd.conf, but client seems to ignore that and tries to connect to 192.168.1.1
03:47
doing a manual connect to 192.168.1.128 from the client works though
03:47
<alkisg>
nubae: did you try nbdroot=1.2.3.4:2000 like I told you yesterday?
03:47
(i.e. nbdroot=192.168.1.128:2000)
03:48
<nubae>
from the client, yes
03:48
<alkisg>
No, from pxelinux.cfg/default
03:48
<nubae>
ah no, havent tried that
03:48
<alkisg>
Try to put it as a kernel parameter there
03:51
<nubae>
same problem, at the end it says eth0 configured at 192.168.1.128 192.168.1.1 192.168.1.1 255.255.255.0, does that sound right?
03:56
when restarting the nbd server I get:
03:56
Restarting Network Block Device server: Stopping Network Block Device server: nbd-server.
03:56
** (process:16127): WARNING **: Could not parse config file: Could not open config file.
03:56
<alkisg>
It sounds like you have the dhcp server of the router open :)
03:57
But nbdroot should solve that problem...
03:57
<nubae>
I dont, I guarantee it
03:57
<alkisg>
Can you pastebin your dhcpd.conf ?
03:59
<nubae>
http://pastebin.be/23794
03:59
is it normal though, the nbd cannot parse config file?
04:00
<alkisg>
Yes, there's no config file
04:00
<nubae>
ok
04:00
<alkisg>
nubae: can you put break=mount in pxelinux.cfg/default,
04:00
ah no
04:01
You don't need that, you already get a busybox
04:01
So, what do you see with `cat /tmp/net-eth0.conf` and with `cat /tmp/dhcp-info-i-don't-remember-the-exact-name` ?
04:01
<nubae>
I'm putting the sleep further up cause it doesnt seem to sleep properly
04:01
net-eth0 doesnt exist
04:01
neither does dhcp-indo
04:04
<alkisg>
nubae: try with break=mount
04:05
<nubae>
just did
04:05
<alkisg>
then, cat /tmp/net-eth0.conf && cat /tmp/dhcp-info.conf
04:05
<nubae>
no difference
04:05
<alkisg>
What, they don't exist with break=mount?!
04:05
That's too weird
04:05
<nubae>
nope
04:05
<alkisg>
Do you have write access to /tmp ?
04:06
<nubae>
yeah directory is 777
04:06
owned by root though
04:07
<alkisg>
Something's really wrong with the mint initscripts :)
04:07
<nubae>
i guess... will have to use Ubuntu proper I guess
04:09
can I create an ubuntu server VM on the mint machine to do the ltsp stuff?

04:25Egyptian[Home] has joined #ltsp
04:36
<nubae>
alkisg: any idea if I can use a VM as a server instead of reinstalling with Ubuntu?
04:36klausade has joined #ltsp
04:36
<alkisg>
nubae: sure
04:36
<nubae>
Have u ever set it up that way?
04:36
<alkisg>
Yup
04:36
But if you're around in the afternoon, I may be able to help more with your current problem
04:37
<nubae>
any noticable lag or speed or something?
04:37
<alkisg>
Since you used --dist=karmic, you shouldn't be having anything mint-specific in your chroot
04:37
<nubae>
alkisg: well I'll leave it as it is then, but this could be a bit of nasty problem probably buried in the init scripts
04:37
<alkisg>
So maybe your network is your problem, or a bug in the upstream scripts, and not mint...
04:38
nubae: can you try putting stgraber's ppa (or my ppa) in both your server's and chroot's sources?
04:38
<nubae>
sure... I could also try and build a different dist in the chroot
04:38
<alkisg>
That way, if there's a bug there, and it was solved between karmic <=> lucid, we won't have to deal with it again...
04:38
<nubae>
ok
04:38
<alkisg>
No need, karmic is fine
04:38
sudo add-apt-repository ppa:stgraber
04:38
apt-get update / dist-upgrade
04:38
both in server + chroot
04:39
<nubae>
I've got a dns problem in the chroot it seems
04:40
cant resolve host osiris (my server)
04:40
maybe I have to manually define it in the chroot?
04:41
<alkisg>
cp /etc/resolv.conf /opt/ltsp/i386/etc/resolv.conf
04:42
Also don't use sudo in the chroot
04:42
<nubae>
yeah its already thesame
04:42
<alkisg>
You're already root there
04:42
<nubae>
I added osiris to hosts
04:42
that should fix it
04:43
add-apt-repository command not found in chroot
04:43ogra_ has joined #ltsp
04:43Selveste1 has quit IRC
04:43
<nubae>
wait that makes no sense
04:44Selveste1 has joined #ltsp
04:44ogra has quit IRC
04:45
<nubae>
hmm, alkisg, ideas? command not found, what do I need to install
04:45
<alkisg>
nubae: wget http://ts.sch.gr/repo/add-ppa.sh -O /tmp/add-ppa.sh
04:45
sh /tmp/add-ppa.sh stgraber
04:45
That should do it...
04:46
(I got this for other teachers here - so don't pay attention to any greek messages :))
04:46
<nubae>
ok so add-ppa is the command?
04:47
right ok done
04:47
love the cyrillic :-)
04:48
<alkisg>
Nah, Greek isn't cyrillic
04:49ogra_ is now known as ogra
04:49ogra has joined #ltsp
04:49
<nubae>
oh it isnt?
04:49* nubae feels silly now
04:49
<alkisg>
Some Greek priests invented the cyrillic alphabet when they tought christianism to russians etc
04:49
But the greek alphabet was there eons ago..
04:49
<nubae>
I'm European.. I shouldn't make American mistakes :-)
04:49
<alkisg>
Heh :D
04:50
<nubae>
ok, so rebuild image and update?
04:52
<alkisg>
Also update-initramfs -u
04:52
(in the chroot)
04:52
<nubae>
exit
04:52
oops
04:52
heh
04:53
hmm dist=karmic doesnt work now
04:54
ah never mind, forgot to delete /opt/ltsp/i386
04:55
wait, its not using the ppa now is it?
04:55F-GT has quit IRC
04:58
<nubae>
alkisg: ?
04:58
<alkisg>
nubae: why did you delete the chroot?
04:58
<nubae>
yeah
04:58
<alkisg>
You just had to update it...
04:58
<nubae>
I'm just worried its not using the ppa
04:59
oh ok
04:59
well its building now, but I did --dist=karmic
04:59
will that use the ppa?
04:59
<alkisg>
Nope
04:59
You'd have to use --extra-mirror for this
04:59
Just add the ppa in the chroot after it finishes building
05:00
(with the command I pasted above)
05:00
<nubae>
oh, shit.. right....
05:00
:-)

<nubae>
litlebuda: u'll need to be more specific
05:57
<Appiah>

05:57
this is not really a ltsp issue
05:57

quick question for the room
07:06
I'm currently running softphones on ltsp as localapps and using pulse audio suppression.
07:07
which works great until the phone loses focus and then they get static because p ulse doesn't know what's going on, but it's being used for other apps
07:07
since I don't need sound for anything but the phones, is there a way to run the whole desktop session with pasuppression?
07:07
or to set the users up to just wrap everything in it and skip pulse alltogether?

<Gadi>
anivair: set SOUND_DAEMON to a bogus value, and pulse will not run at all on the client
08:13
anivair: then, you will be good to go
08:14
<anivair>
where is that value set?
08:15
<Gadi>
in lts.conf
08:15
<anivair>
thanks. I'll give that a shot
08:15
<Gadi>
so, you can add: SOUND_DAEMON=bubba
08:15
:)
08:16
you will likely get a warning saying that it cannot start bubba
08:16
<anivair>
that'll be amusing if someone else inherits my job in the future
08:16
<Gadi>
but, other than that, you'll be ok

gotta have fun with it
08:16
its a moral imperative
08:17
<anivair>
(that is how you m otivate someone)
08:17
now I just cross my fingers that nobody comes out with a bubbe sound daemon
08:17
<Gadi>
(of course, you will need to take out pasuspender and just call twinkle directly once you do this, as pasuspender will have nothing to suspend)
08:17
<anivair>
right
08:17
I'll play with it this weekend
08:18
I'm also going ot write a little script that kills twinkle and removes twinkle.lck if it exists before it starts the program, because I'm getting a LOT of in stances where twinkle shuts down funny and gets hung up at start
08:18* Gadi makes mental note that we should actually just make "False" one of the values for SOUND_DAEMON
08:21
<anivair>
heh. true

morning... is there a lts.conf variable to set the timezone?
09:27

sbalneav: "docs" :: For the most current documentation, see https://sourceforge.net/apps/mediawiki/ltsp/index.php?title=Ltsp_LtspDocumentationUpstream
09:27
<sbalneav>
ftherese: yes there is.
09:27thunsucker has joined #ltsp
09:27
<ftherese>
I am reading the LTSPManual... so it is just in another location?
09:28
I just downloaded that file and was reading it
09:29
<sbalneav>
Chapter 10
09:29
page 34
09:29
General Thin CLient Parameters
09:29
TIMEZONE
09:29
<ftherese>
ok got it sorry...
09:29
do you know what format it should be in?
09:30
<sbalneav>
I would expect the normal timezone format
09:31
<ftherese>
so I could try UTC+0100
09:31
<sbalneav>
in the code it copies:
09:32
cp /usr/share/zoneinfo/$TIMEZONE /etc/localtime
09:32
<ftherese>
maybe it doesn't like the +0100, because it is off by an hour
09:32
but that is what `date` looks like
09:32
<sbalneav>
so I would expect you'd need to do the normal America/Winnipeg format
09:33
where are you?
09:33
<ogra>
what ? there is no Canada in there ?
09:33
<sbalneav>
ogra: No, we don't rate
09:33
<ogra>
booo
09:33* ftherese looking at /usr/share/zoneinfo
09:33
<ftherese>
France
09:33
Paris
09:34
well... not paris, but paris timezone
09:34
<sbalneav>
so Europe/Paris
09:34
<ogra>
Europe/Paris then
09:34
<sbalneav>
TIMEZONE=Europe/Paris
09:34
<ftherese>
ok thanks
09:35
also, I was wondering about the guest login feature - does it look for a guest account?
09:36
how does it work?
09:36Faithful has quit IRC
09:37
<ftherese>
I just tried enabling LDM_GUESTLOGIN or whatever it is, it made a button, but when you push it the computer just thrashes around for a while until it finally returns to the LDM login screen

ftherese: i don't see anything wrong with your lts.conf
09:48
i'm researching it now
09:49
<ftherese>
I think there must needs be a guest account installed on the server or something, but I don't know what it should look like - I really don't even know how it works or if it works
09:50
<thunsucker_>
ftherese: is gdm-guest-session installed?
09:51Faithful has joined #ltsp
09:51
<ftherese>
on the server or the client?
09:51
<thunsucker_>
try the server
09:51* ftherese is also looking at https://help.ubuntu.com/community/UbuntuLTSP/AutoLoginFeatures
09:51
<thunsucker_>
dpkg -s gdm-guest-session
09:52
<ftherese>
yeah... that is installed
09:52
I am going to try adding LDM_ALLOW_GUEST
09:52
to see if that works
09:54alkisg has joined #ltsp
09:55kusznir has joined #ltsp
09:58
<ftherese>
that didn't do it... timezone is still wrong too - thunsucker_
10:00
<thunsucker_>
ftherese: i know this is generic but i always ask, have you updated your server and the chroot?
10:00
sudo apt-get update && apt-get dist-upgrade on both?
10:03
<ftherese>
I just did this morning... I can make sure there are no packages though
10:03
(four different servers to check...)
10:04
looks like the next kernel version just came out
10:05
it will take a while
10:05
<alkisg>
ftherese: you need LDM_USERNAME and LDM_PASSWORD in lts.conf for the guest feature to work
10:05
If you don't specify them, they default to the client hostname
10:05
I.e. ltsp123/ltsp123 - so you'd need a user account with that name and password
10:06
<ftherese>
ah!
10:06
bingo
10:06

<ftherese>
maybe it is in the lts.conf man file
10:06
<alkisg>
Yeah, it's there... http://manpages.ubuntu.com/manpages/lucid/en/man5/lts.conf.5.html#toptoc12
10:07
<ftherese>
the only thing in the LTSPManual is the LDM_GUESTLOGIN value
10:07
*var
10:08
is there any way to cut down on the number of home dirs?
10:08
<alkisg>
ftherese, it's also in the manual, in 21.4 Auto login features
10:08
What do you mean by that?
10:08
<johnny>
ftherese, no..
10:08
<alkisg>
Have 3-4 users share the same home dir?
10:08
<johnny>
programs don't like running alongside other programs
10:09
err other instances of the same program that is
10:09
firefox is especially bad at it
10:10
hacky.. but neat ..
10:10
http://chris-lamb.co.uk/2008/01/24/can-you-get-cp-to-give-a-progress-bar-like-wget/
10:11
<ftherese>
I know, but what I don't like is creating 100 guest home dirs to be routinely filled with firefox cache and waste space on the server
10:11
and whatever other temporary files it happens to create
10:11
or the user happens to download or copy during their brief stay
10:12
maybe a script at the end that just completely erased the home directory...
10:12
<johnny>
that's what i do
10:12
once a day
10:12
<alkisg>
ftherese: you need 100 guest accounts for 100 PCs? You could make them under /home/guests/guest88, and also make a script that erases everything at logon...
10:12
<johnny>
not completely erase their /home.. just the contents of ~/
10:12
<ftherese>
right
10:13
I would just assume they use the ltspXXX user/pass and not have to fill out the lts.conf file with mac addresses
10:13
etc
10:14
<johnny>
http://pastie.org/853678
10:14
that's what i use
10:14Selveste1_ has quit IRC
10:14
<ftherese>
so... in the $CHROOT/usr/share/ldm/rc.d/ make a S or K script?
10:15
<johnny>
i do it on the server ftherese
10:15
cron the sript at night
10:17
<ftherese>
ah... that would be simpler than rebuilding the thinclients
10:18
<alkisg>
Except that the next guest would see what the previous guest visited on firefox etc
10:18
<johnny>
alkisg, at that point you'd set it to go in private mode
10:18
doesn't the firefox in karmic ship with firefox that can do private mode?
10:18
<alkisg>
johnny: it's not only firefox...
10:18
<johnny>
nobody ever logs out of terminals at my store
10:18
they just stay on
10:18
so even such a script would never work
10:18
since nobody logs out
10:19
<alkisg>
And you clear their homes while logged on?
10:19
<johnny>
no
10:19
at night only
10:19
after close
10:19
<alkisg>
I'd put a sign somewhere that logoff erases everything, so those concerned with privacy could just logoff
10:19
<johnny>
ftherese, if you think your users will actually log out.. then such a thing is probably wanted ..
10:20staffencasa has joined #ltsp
10:20
<johnny>
alkisg, i would use a script if you wrote it..
10:20
only problem now.
10:20
is having to actually put such a script in the chroot
10:20
<alkisg>
Heh :)
10:20
I don't think it's needed in the chroot
10:20
<johnny>
i hate having to remember mods i've done to the chroot :)
10:20
ah.. it also uses accounts on the server for other things..
10:21
<alkisg>
...but I don't know offhand where I'd put it, to ensure that it's the first thing to run
10:21
If '
10:21
if username==guest*, then erase everything
10:21
That shouldn't bother him with other accounts
10:22
<johnny>
on login is probably better
10:22
as people often hard power off machines
10:22
<ftherese>
I have a script that builds a new chroot from scratch and adds everything for localapps firefox, chromium, openoffice etc., with the localdev support etc...
10:23
because after you upgrade through a few kernel releases the size of the thin client just gets fatter and fatter
10:23
<alkisg>
ftherese: try `apt-get clean` on the chroot
10:23
..and also purge any older kernels
10:24
It shouldn't grow larger over time...
10:24
<ftherese>
I used to do that... but it always seemed to continue to grow
10:24
I think now it has to do with the chromium versions
10:24* alkisg always mounts /var/cache/apt/archives nowadays, so it's faster and also he doesn't have to run apt-get clean...
10:25
<sbalneav>

<ftherese>
?
10:25
what's that
10:25
<johnny>
sbalneav, i posted that here for your yesterday :)
10:25
but you weren't around
10:27
<ftherese>
timezone is still incorrect
10:27
<sigh>
10:27
oh well... it isn't like anyone stares that the login screen to know what time it is
10:28
<thunsucker_>
ftherese: someone the other day was in here, and I believe found a way to make that black text white, so it wouldn't show up
10:28
<ogra>
are you sure its the timezone and not the clock itself ?
10:28
<alkisg>
ftherese: try to set UTC=yes or no in the chroot
10:28
/etc/default/rcS - compare server & chroot
10:29
<sbalneav>
johnny: hah, cool
10:29
Great minds think alike
10:29
fools seldom differ :)
10:30
<ftherese>
after signing in the time is correct
10:30
it is only on the LDM screen
10:30
<alkisg>
ftherese: grep UTC /opt/ltsp/i386/etc/default/rcS
10:30klausade has joined #ltsp
10:31
<ftherese>
UTC=yes
10:31
I tried using timezone="CET" #(central europe)
10:31
and I tired timezone = "UTC+0100"
10:31
<alkisg>
ftherese: try with UTC=no
10:32
<ogra>
on the login screen you see the actual hardwareclock of the thin client ...
10:32
if you logged in you see the time on the server
10:32
<ftherese>
ahhh...
10:32
<ogra>
if the clock on the client is wrong you can play for ages with timezones and wont get it right :)
10:33
<ftherese>
well... this is actually the same problem with two different computers
10:33
maybe both of them have the wrong machine time
10:33
<ogra>
what you can do is set up an ntp server on the server and make the clients just update their time on boot
10:33
<ftherese>
I've only checked on those two also
10:33gnunux has quit IRC
10:55
<nubae>
alkisg: good news, that worked...
10:55
<alkisg>
nubae, which one?
10:55
<nubae>
so something in the ppa fixed it
10:55
<alkisg>
Ah, ok, a solved bug ;)
10:55
<nubae>
heh, updating the chroot
10:55
yeah except we have no idea which bug now :-)
10:56
anyway, I guess I can write up a solution for anyone wishing to use Mint for ltsp
10:57
<alkisg>
nubae: you could do it with EXTRA_MIRROR to be easier, instead of updating the chroot later on
10:57
<nubae>
yeah true
10:57
<alkisg>
nubae: have a look at my fat client page in the wiki, I mention about it (and stgraber's ppa)
10:57
<nubae>
it feels a bit weird writing a solution without knowing what problem it fixes though
10:58
I guess the fixes will be in Lucid
10:58
<alkisg>
Yup, ltsp 5.2 is in lucid
10:59
<nubae>
feels like the numbers go up so slowly for ltsp
10:59
<ftherese>
that is actually kind of reassuring
11:00
<nubae>
for stability, yeah
11:01
<ogra>
well, ltsp 5 is at revision 1702 ... depends what numbers you watch ;)
11:01
<nubae>
but its still quite unpredictablle from one distro to another
11:01* sbalneav declares ltsp 5.2 == LTSP 7
11:01
<nubae>
heh
11:01
<ogra>
sbalneav, are you SuSE ?
11:01
<nubae>
would work for marketing
11:01
windows more like
11:01
<ogra>
SuSE predates that
11:01
they made such a jump before
11:02
<nubae>
they started slowing down with their numbers
11:02
11.3 is like 2 years of 11
11:02
little correlation with their release numbers unfortunately
11:03* sbalneav declares LTSP 7 == "Incontinent Ibis" release
11:03
<ogra>
well, it might be renamed to elliotOS anyway, who knows :)
11:03
<nubae>
elliotOS?
11:03
whats that?
11:03* sbalneav declares sbalneav "King of All Newts"
11:04

Been a long time since I played those sorts of games
11:07
<ogra>
makes one feel old, eh ?
11:07
<nubae>
I downloaded world of goo yesterday...
11:08
<sbalneav>
I still play nethack from time to time
11:08
I got my kids into it for a while.
11:08
<ogra>
heh
11:08
<sbalneav>
nethack, rogue, the old Zork series
11:08
fun times.
11:08* ogra switched to falcons crest a while ago
11:08
<sbalneav>
nethack's still being maintained, oddly enough.
11:08
<ogra>
but work doesnt really leave me time
11:09* ogra has to extend ARMs ... http://www.bild-hoster.de/images/Gofmann/saw.jpg

<sbalneav>
My kids have an Xbawks. Sometimes they even let me play.
11:10
<nubae>
hehe
11:10
<sbalneav>
Only game on it I've REALLY enjoyed so far is Portal.
11:10* ogra has a wii he uses twice a year or so
11:10
<nubae>
wii is more fun
11:11
I softmodded mine
11:12
the sports games are fun, and for retro nostalgia, new super mario bros
11:13
<ftherese>
just curious: is there a script that can be run on the server as a thin client is logging in, without the script being in the thin client?
11:14
<johnny>
sbalneav, ...
11:14
<ftherese>
in other words... can I write a script that will delete a guest user's home directory contents without having to rebuild the chroot?
11:14
<johnny>
http://chris-lamb.co.uk/2008/01/24/can-you-get-cp-to-give-a-progress-bar-like-wget/5
11:14
<ogra>
you can write something that checks for LTSP_CLIENT on the server and run it from /etc/xdg/autostart
11:14
<johnny>
sbalneav, .. thats' for you
11:14
fun hackiness
11:15
<ogra>
johnny, yeah ... /me saw that this morning
11:16
<alkisg>
ogra, stuff in /etc/xdg/autostart do not block, so they could even start after the user has opened firefox... is there some place _before_ that, that also blocks?
11:16
<ogra>
hmm, good question
11:16
to be honest, i dont know
11:18
<sbalneav>
johnny: yeah, nothing like slowing down a copy by 4-5 times by running it through strace just so you can get a progress bar.
11:18
<johnny>
of ourse
11:18
still a neat hack tho
11:18
<alkisg>
johnny: rsync does have a bar ;)
11:19
Gadi: could that SOUND_DAEMON thing be also used for fat clients? I.e. make it default to false when LTSP_FATCLIENT=True?
11:20
<Gadi>
alkisg: if thats the desired behavior?
11:20
<alkisg>
Gadi, what does it do exactly?
11:20
<Gadi>
SOUND_DAEMON=False will simply not run pulseaudio on boot and not spit out a warning message
11:21
all of our other values do *something*
11:21
we didnt have one that does *nothing*
11:21
:)
11:21
<alkisg>
:)
11:21
<Gadi>
if all you run is rdesktop, you probably do not want pulseaudio running
11:22
it just adds overhead and degrades performance
11:24
<alkisg>
Sorry for fat clients we set SOUND=False so that covers pulse as well :)
11:25
<nubae>
is there an updated LDAP howto for karmic/lucid?
11:28
<alkisg>
Yup, sbalneav has uploaded one in the edubuntu wiki
11:28
I don't remember the link offhand...
11:28
<nubae>
oh nice... I'll take a look
11:29
<alkisg>
I wonder if we can use ldm in standalone workstations, to get ssh authentication instead of using ldap...
11:29
<thunsucker_>
nubae: https://wiki.edubuntu.org/Edubuntu/WikiSite/SimpleLDAPSetup

(but now with the fat clients plugin I don't care much... :D)
11:29
<ogra>
alkisg, if anyone every makes it a real dm
11:29
*ever
11:29
<alkisg>
ogra, you mean the debconf entry?
11:29
<ogra>
i mean the whole packaging
11:30etyack has left #ltsp
11:30
<nubae>
thanks
11:30
<ogra>
you have to fulfill a lot of requirements to have it be a real dm in debian or ubuntu

ogra, any links, except for the pax-dm page?
11:31
<chrishuttman>
i was here yesterday, having trouble with an ubuntu distro upgrade to 10.04, decided to just reinstall 9.10
11:31
wanted to say thanks for the 10.04 help
11:31
and also ask is sabayon still the way to go to manage thin client users?
11:31
<ogra>
alkisg, i think vagrant researched that once and gave up
11:32
<alkisg>
ogra, yeah, he gave me that link, I think we're OK on that part
11:32
<sbalneav>
chrishuttman: Sabayon is definitely one of the methods.
11:32
You'll need to install Sabayon packages from my PPA
11:33
I'm now one of the upstream Sabayon maintainers.
11:33
<ogra>
alkisg, next would be to have your own upstart job in ldm to make it independent of ltsp-client ... that will be the hardest part to do without breaking ltsp :)
11:33
<chrishuttman>
are the ones in the main channels broken?
11:33
<sbalneav>
chrishuttman: Correct.
11:33
<chrishuttman>
awesome
11:33
<sbalneav>
They've been fixed in lucid.
11:33
<chrishuttman>
ha :)
11:33
<alkisg>
ogra, well anyway I suppose the new libpam_ssh that sbalneav is looking to make will fulfill that need better than a packaged ldm :)
11:34
<chrishuttman>
sbalneav: if i'm starting from scratch using your PPA's installs, should I be good?
11:34etyack has left #ltsp
11:37
<chrishuttman>
and once i add your ppa, do i need to remove the original sabayon package?
11:39
<alkisg>
chrishuttman: sudo add-apt-repository ppa:sbalneav
11:39
sudo apt-get update
11:39
That should be all.
11:40
<chrishuttman>
thanks guys
11:40
<alkisg>
The sabayon package would be automatically updated - don't worry about removing the old package etc.
11:40
<sbalneav>
chrishuttman: no, they'll be updated
11:40
no need to worry about removing the old package

<jontheisg>
ok, sorry. so I have a question - where does one find instructions for LTSP setup with Ubuntu 9.04?
12:32
aim is for help/documentation with multiserver environment
12:33
<nubae>
!docs
12:33
<ltspbot`>
nubae: "docs" :: For the most current documentation, see https://sourceforge.net/apps/mediawiki/ltsp/index.php?title=Ltsp_LtspDocumentationUpstream
12:33
<nubae>
and the wiki should help too
12:33
!wiki
12:33
<ltspbot`>
nubae: "wiki" :: the LTSP wiki. You can find it at http://wiki.ltsp.org
12:34
<nubae>
hmmm it lies, best wiki is actually here: https://help.ubuntu.com/community/UbuntuLTSP/
12:34
johnny: does sound work on kde clients by default for karmic?
12:34
<johnny>
i have no idea
12:34
i don't use kde
12:34
i would assume so..
12:34
but.. who knows ..
12:35
kde is switching to pulseaudio at some point
12:35
or perhaps already has..
12:35
<nubae>
hmm yeah doesnt work for me, but I'm wondering if its kde related or something else
12:35
<jontheisg>
ok, new to LTSP but not IT.. are network setups that are multi-server meant to have more than one tftpboot system?
12:35
<johnny>
multiserver?
12:35
just different application servers?
12:35
i think you only need one tftpboot dir..
12:35
could be wrong tho..
12:35
<nubae>
they can but dont have to
12:36
<jontheisg>
the intent is to spread the thinclient load across multiple server hardware for best performance
12:36
<nubae>
using clusterltsp gives u multiple app servers
12:36
<jontheisg>
can it be done without clustering or no?
12:36
<nubae>
thats clusterltsp jontheisg
12:36
well by default LTSP is non clustered
12:37
but it doesnt span across hardware on the server end
12:37
<jontheisg>
ok. understood. does the wiki describe setup of clusterltsp
12:37
<nubae>
it does it on the client end
12:37
yes it does
12:37
<johnny>
it does?
12:37
they have their own site
12:37
<nubae>
works quite well in later Ubuntu distros
12:37
<jontheisg>
ok ill check and read
12:37
we were going to put up 8.04LTS Ubuntu for LTSP - but I am leaning toward 9.04. Thoughts?
12:37
<nubae>
the link in the wiki might send u to cluster specific link
12:38
I'd wait for LTS version
12:38
<jontheisg>
around 200 clients and 3 hardware servers available.
12:38
<nubae>
10.04
12:38
y would u want 9.04 and not 9.10?
12:39
the LTS should be out in 2 months I believe, or is it 4...
12:39
<jontheisg>
generic ubuntu question - is 9.10 less stable than 9.04? I have had more success with 9.04??
12:39
its due in April
12:39
10.04
12:39
<nubae>
I've tested cluster on karmic, and that ran quite well
12:39
I'm sure it runs on lucid too
12:39
<jontheisg>
kewl
12:39
right now there are 2 network subnets that are servicing two client pools
12:40
<nubae>
johnny: any idea how I can test my sound setup on kde clients?
12:40
<jontheisg>
we are trying to flatten network, increase LTSP performance and improve network design. Right now there are two LTSP4? on CentOS
12:40
<nubae>
there seems to be no documentation for it
12:41staffencasa has quit IRC
12:41
<jontheisg>
We are going to take them to Ubuntu-land in the near future
12:41
<nubae>
well, u'll certainly see a difference with ltsp 5.2
12:41
<johnny>
no nubae .. no kde ever here..
12:41
<nubae>
darn, I have no idea where to even start...
12:42
<jontheisg>
any thoughts on using proxmox or vmware or virtualization on ltsp server cluster?
12:42anivair has quit IRC
12:42
<nubae>
jontheisg: thats how I did it
12:42
<jontheisg>
really. excellent
12:42
<nubae>
using proxmox
12:43
the howto is based on that
12:43

seperating across vms makes a lot of sense since its the one thing where LTSP is pretty vulnerable since everything runs off one machine otherwise and the server going down means death to all clients
12:45
<jontheisguy>
right
12:45
hey im looking at wiki.ltsp.org - where are the proxmox items?
12:45
<nubae>
https://help.ubuntu.com/community/UbuntuLTSP/LTSP-Cluster
12:45
its in the ubuntu wiki
12:46
but is probably relevant for other supperted distros too
12:46
I'm planning or rolling out cluster myself actually for a new school setup
12:47
<jontheisguy>
same here.. volunteering at a school in CO, USA
12:47
<nubae>
the openvz pages talk about proxmox
12:47
well openvz is proxmox iirc
12:48
<jontheisguy>
@nubae sure.. where is your school located?
12:48
<nubae>
Spain
12:48
Southern coast
12:48
<jontheisguy>
fantastico
12:48
<nubae>
:-)
12:49
<jontheisguy>
so with this new info - gracias a nubae & johnny - I think I am going to look more into LTSP cluster setup
12:49
<nubae>
yeah setting something up for students who have just finished school, or expats wanting to learn computers, office the internet
12:49thunsucker_ has quit IRC
12:50
<nubae>
don't get overwhelmed by it, there are a lot of instructions
12:50
<jontheisguy>
just finished school - as in college - or secondary?
12:50
<nubae>
but the end result is worth it
12:50
yeah, diploma based... not really college/uni
12:50
based on British system of education
12:51
<jontheisguy>
cool
12:51mikkel has joined #ltsp
12:51
<nubae>
setting it up with a couple IT teachers, and we've all worked in various schools in the area
12:51
<jontheisguy>
excellent
12:51
<nubae>
I'm just unsure about the Linux angle
12:52leio has quit IRC
12:52
<nubae>
but I believe people will accept it if we make the underlying OS not so important
12:52
<jontheisguy>
do you plan to seperate any services or all on LTSP cluster?
12:52
CUPS, Samba, NIS, etc
12:52
<nubae>
yeah I'll separate services in VMs
12:52
LDAP instead of NIS
12:53
so windows/osx clients can log on

one of the side projects for me is to create LDAP/Radius server
12:53
should be interesting
12:53fudoreaper has joined #ltsp
12:54
<nubae>
yeah I set up LDAP for dapper, but there are howtos for the latest distros now so should be relatively straight forward
12:55
<jontheisguy>
any gotchas to look out for with LDAP setup. I found documentation for it, just wanting any suggestions regarding best practices ;)
12:55leio has joined #ltsp
12:57
<nubae>
not really sure, last time I took a look was a couple years back with dapper, but I'm actually installing right now so I'll let you know if I run into anything
12:57
<jontheisguy>
that'd be great.
12:57
thanks for your patiencia

alkisg: u have experience with kde clients, my sound isnt working... wondering where I should look
13:06
?
13:07
<jontheisguy>
@nubae have you checked into which module(s) are being loaded in the lts.conf?
13:08
<nubae>
jontheisguy: nope, but sound should be loaded by default, in any case I'll double check, its a good idea

im going to work with some virtualized servers... thanks nubae and others who helped!

<nubae>
I get /etc/X11/Xsession.d/80_ltsp-sound: 7: /usr/bin/asoundconf: not found
13:33
in my logs (xsession-errors), any ideas?
13:38
looks like this is a deep issue of kde... I thought kde was more developed for ltsp now...
13:42
super weird, so pulseaudio works locally, but when I try and play any media it plays on the server
13:43
doing a test however sound works on the client
13:44
<abeehc>
what's kde use, esd?
13:44
<johnny>
no..
13:45
they used to use arts..
13:45
<nubae>
its using pulse now
13:45
<johnny>
ah
13:45
<nubae>
and it runs fine when I test
13:45
they split it into video /audio /communication
13:45
I set pulse as default, but when I play a media file it plays on the server
13:46
<abeehc>
what are you using to play
13:46
<nubae>
however a sound test plays on the client
13:46
makes no sense
13:46
<abeehc>
and what's a sound test?
13:46
vs. playing something
13:46
<nubae>
system settings >> sound
13:46
<abeehc>
i would imagine first class kde apps should obey the pulse setting
13:46
and work as normal?
13:47
but random media clients will do random things?
13:47
what's the app that plays on the server
13:47
<nubae>
lets see let me try vlc
13:47
<abeehc>
vlc is flexible enough you can tell it what sound daemon to interact with i'm sure
13:48
<nubae>
lol ure right... mplayer plays locally
13:48
draganplayer/vlc play on server
13:48
now that is weird
13:48
<abeehc>
i see a package in jaunty repos for vlc-plugin-pulse
13:49
<nubae>
well mplayer suits me fine, I'm just used to using kde
13:49
I mean vlc
13:49
<abeehc>
right on
13:49
<nubae>
vlc-plugin-pulse was already installed
13:49
<abeehc>
This plugin adds support for PulseAudio to the VLC media player. To activate the audio output module, use the `--aout pulse' flag or select the `pulse' audio output plugin from the preferences menu.
13:50
i imagine that might work I dunno
13:50
i haven't struggled with sound just yet
13:50
<nubae>
hmmm my vlc is randomly crashing
13:50
but if it works with mplayer theres probably a way
13:50
now for local devices :-)
13:51
I guess there aren't that many people using kde ltsp
13:53
<abeehc>
i'm not too sure
13:54
<nubae>
video is really slow though, I guess this is cause I have a X1350 ati
13:54
I might have to install the prop drivers in the chroot
13:56
yeah cant do fullscreen at all

I've installed K12LTSP using the F10 "live" DVD image four or five times now. I can follow the K12Linux Quickstart Guide that appears on the desktop and get the networking operational, but I am having a tough time remembering how to install the K12 apps. In the back of my mind it was an RPM I install, but I can't recall the name, nor am I having any luck with the documentation on the K12linux wiki. Wishing the line with that solution w

Is there a location that thin clients log information for boots
16:32
<_UsUrPeR_>
yotux: on the client itself, in /var/log
16:33
in order to access that, create the following file: /var/lib/tftpboot/ltsp/i386/lts.conf . In the file, put the following: http://pastebin.com/QKxWxN7P
16:33
<yotux>
my thin client will not boot so that would be hard to get to
16:33
<_UsUrPeR_>
after boot, you should be able to access shell by pressing CTRL+ALT+F2
16:34
yotux: in that case, check /var/log/syslog
16:34
<yotux>
that would be on the server correct?
16:34
<_UsUrPeR_>
yotux: correct, yes
