<Barni_>
i wanna to do when i plug an USB FlashDrive that to be mounted automatically for the users and to bring me up on the desktop a folder which is accessing diretly that
08:45
and i did not find any help
08:45
regarding this
08:46
<patrickb>
are you able to get them to mount manually?
08:47
<Barni_>
yes
08:48
but i wanna when i insert the USB flash to create me on desktop a link to the files , after when i unplug to disappear this link
08:49
<patrickb>
i use a permanant link on the desk top to USB keys local devices
08:50
<Barni_>
and how did you done when u insert the usb flash on LSTP client to mount it automatically
08:50
<patrickb>
but i use a very small setup to allow my kids to access Internet do homework on terminals that are set up in thier bedrooms
08:50
<pscheie>
Barni_: are you using ltsp 4.2?
08:51
<Barni_>
yes
08:51
<pscheie>
it should happen automatically
08:51
that's the big feature of 4.2
08:51
have you gone through the 12-step troubleshooting guide on the wiki?
08:52
<Barni_>
i don't know, where is that exactly
08:52
?
08:53
<pscheie>
http://wiki.ltsp.org/twiki/bin/view/Ltsp/LTSP-42-LocalDev
08:53
It's near the bottom
08:54
On my clients, I plug a USB stick in and a folder icon appears on the desktop.
08:54
I click on the icon, it opens, and there are the files.
08:54
I close the folder when I'm done, and then just remove the USB stick
08:54
and the icon disappears. No need to unmount.
08:56
<Barni_>
where exactly ... i followed it ... i have FC4

Barni_: If it's not working for you, go through the troubleshooting steps AND
09:06
record the output from each step and post that to the LTSP mailing list.
09:07
Or try to catch sbalneaves here on the IRC.
09:07
He wrote the LDA stuff and can usually figure out the problem, but
09:07
he needs the exact output from each of the steps to figure it out (which is why he wrote the 12 steps)
09:10Skarmeth has left #ltsp
09:13
<Barni_>
now when i plug in an USB falsh drive on the desktop appear Removable Device
09:13
but an empty folder
09:14
and the flash drive contains data
09:27
<Arsenick-TC2L>
whoa I have a problem with usb stick too.. I can see the data inside but I'm unable to unmount the device corectly..
09:27
<g333k_work>
Hi, if my clients boot but they freezes loading the X... what could be the problem? (yesterday I updated the server IP and added more clients to dhcpd.conf & hosts)
09:31
<pscheie>
g33k_work: did you change the 'next server' setting in dhcpd.conf to reflect the server's new IP?
09:33
<g333k_work>
pscheie, this option is disabled... I realized that I forgot to change the server Ip in lts.conf :$
09:33J45p3r_ has joined #ltsp

<Barni_>
how can i set the LTSP default sound server
09:36
i have SOUND_DAEMON = esd but the xmms is trying to use ALSA by defaut
09:36
?
09:41
<pscheie>
Barni_: You may need to install Gideon Romm's esd-for-alsa package.
09:41
It's on the wiki at http://wiki.ltsp.org/twiki/bin/view/Ltsp/WorkInProgress
09:42
I'm fuzzy on all the sound pieces. Gideon also told me that Real Player 10 uses alsa
09:42
but it won't currently work, have to use RP8
09:43
<Barni_>
i just wanna to do, that all sound applications to use the eSound
09:44
<pscheie>
The problem, as I understand it, is that not all applications do use the same sound system
09:45
<Barni_>
i think
09:45
because when is wanna to play music with xmms it's working after i set CTRL+P the eSound
09:45
but with VPL media player there is no sound
09:45
mplayer music.mp3 also is no sound
09:45efra has joined #ltsp
09:46
<Barni_>
but mplayer -ao esd music.mp3 is working perfeclty
09:46
<efra>

<g333k_work>
Is it easy to set up a ltsp server using CentOS ?
10:15
<pscheie>
g333k_work: The easiest way to install ltsp and CentOS would be to use K12LTSP 4.2.3EL
10:15
which is LTSP packaged with Centos
10:18
<g333k_work>
pscheie, OK thanks.. let me try it
10:18
pscheie, ltsp 4.2 ?
10:18
<pscheie>
ftp://k12linux.mesd.k12.or.us/pub/K12LTSP/
10:18egypcio has quit IRC
10:19
<pscheie>
look for the ones with EL in the name
10:20
<g333k_work>
pscheie, do you have a http site? I'm behind hundred firewalls and proxys
10:20egypcio has joined #ltsp
10:21
<g333k_work>
pscheie, well I'l use gftp with no passive mode
10:24
<pscheie>
let me look...hold on
10:24
you could also use rsync
10:27
for http, try http://gd.tuwien.ac.at/opsys/linux/k12ltsp/4.2.1EL/
10:29
<Barni_>
how can i set that all sound applications to use the eSound ???
10:30
<pscheie>
I think you have to set each application individually
10:31
<Barni_>
there is no common settings available?
10:32
<pscheie>
I don't think so, not today. Each app has its own means of setting sound config.
10:32
Many/most are moving to using gstreamer or phonon which LTSP does support
10:33
and once all apps go that route, apps should just work out of the box
10:33
but I don't think we're there yet.

I've secured a SIP account on the canonical server. If there are any presentations going on in California at the Ubuntu Developers conference, could somebody please post here the conference extensions?
12:24
<jammcq>
joebaker: yeah, we've got a bunch of cool meetings today
12:24
i'll try to hang in the channel and let you know how to find us
12:25
<joebaker>
Thanks jammcq! That Gobby tool is great! I already marked up one of your documents "ltsp-management-gui

hi all, philosophical question here - (sort of) I'm thinking about a fat client deployment. Lots of RAM, perhaps a GIGA speed ethernet interface, good video card and sound card. i want the local client machine to be able to handle very demanding multimedia work locally(on client), like teleconferencing but still be a "client" administratively. Is this doable?
12:41
and does it make sense?
12:41
Have I missed something obvious like an article that revies this entire idea?
12:42
reviews
12:42
<McPolo>
I might get you wrong, but some kind of kickstart-installation?
12:42sbalneav has joined #ltsp
12:42
<bronze>
not planning on clients having any disk.
12:42
want them to netboot.
12:43
<McPolo>
How slow that might be?
12:43
<bronze>
dunno
12:43
they wouldn't need to boot very often
12:43
<jammcq>
bronze: funny you should be asking that question. we have a meeting at 3pm today, to discuss that very feature, and whether or not to put it in the next release of Ubuntu
12:44
<bronze>
at GIGa speed transfer speed won't be too large an issue
12:44
I have a theory:
12:44
<jammcq>
bronze: how many of those "fat clients" do you want to run off a single server?
12:44
<bronze>
There was asecond shooter on the grassy knoll, oops wrong theory
12:44
<jammcq>
:)
12:45
speaking of grassy knoll, 2 weeks ago, i was down in Dallas, and I went and visited that very same grassy knoll
12:45
<bronze>
jammcq: depens on the sever - butr i do see the intenxive multimedia work being done locally on "Super Client" TM
12:45
sorry- cant type today
12:45
<jammcq>
bronze: yeah, but are you talking 5 clients, 50 clients, 500 clients?
12:45
<bronze>
nerves toarns slicghtly grucnged
12:45
<cliebow>
want some lessons?
12:46
<bronze>
cliebow, got surgery shceduled.
12:46
neves are grunched by discs
12:46
<cliebow>
don't do it..it won't help 8)
12:46
at least not for me..
12:46
<bronze>
jammcq 50 to 500.
12:46
<cliebow>
now if theyd done something besides the kness...
12:46
<bronze>
cliebow you've had the surgery?
12:47
<cliebow>
yep..no more kids for me
12:47
<bronze>
jammcq- actualy - thats worng.
12:47
<jammcq>
bronze: 50 clients reading all programs via NFS can be an aweful lot of traffic
12:47
500... well, that's a whole different story
12:47
<bronze>
i see a residental deployment, 1 to 5 units in the home. (blue sky thinking)
12:47
and then business deplyments
12:48
<McPolo>
Sounds better to have kickstart-installation and home-directory via nfs perhaps?
12:48
<bronze>
with medium to alrg numbers of units per organization
12:48muh2000 has quit IRC
12:48
<bronze>
My theory is that most desktop PC will not have disks in them anymore, soonish (3-5 years)
12:49
<McPolo>
Oh damn, there weren't any disks =)
12:49
I have feber, so forgive me.
12:49
<bronze>
jammcq: are you assuming all boot at the same time?
12:49muh2000 has joined #ltsp
12:49
<jammcq>
bronze: check this web page: https://features.launchpad.net/distros/ubuntu/+spec/ltsp-fat-clients
12:49
<bronze>
looking
12:50
jammcq i assume clients load multimedia apps one after booting and keep them resident in memory until next boot.
12:51
<jammcq>
bronze: as long as there's enough memory to keep things resident
12:51
<bronze>
so, excpet for normal X traffic, no extra program load goes over the LAN.
12:52
heh "SuperClient" always has enough RAM! :-)
12:52
(TM)
12:52
:)
12:53
so the fat cleint described in the articxle has a local disk?
12:54
jammcq - what issue determined that those fat clients needed to have a local disk?
12:54
<jammcq>
no clue
12:55
that writeup was done quite a while ago
12:55
<bronze>
oh.
12:55
<jammcq>
and later today, we'll be examining it and figuring out how to proceed
12:56
<bronze>
I see a Super client as having loads of RAM, but only a specific set of media programs to run, which are loaded once, at boot time
12:56
jammcq pm, one liner info?
12:56
<jammcq>
sure
12:57
<bronze>
heh nad my typing isstioll broken
12:57
gad.
12:58
so a Super client if differentiated from a fat client by the lack of a diskm and a fixed set of local programs/apps to offload media work
12:58
s/if/is/
12:59
dang, tiem to rest arms.
12:59

hi, if i have istaled the k12ltsp 5
13:21
is there a graphical tool tho configure the clients
13:22
what are the steps i must folow to begin making work a client?
13:23
<cliebow>
panialex:if you havew configured dhcp and tftp and nfs?
13:23
<panialex>
nop
13:25
<cliebow>
!pastebot
13:25
<ltspbot>
cliebow: "pastebot" is The LTSP pastebot is at http://pastebot.ltsp.org. Please paste all text longer than a line or two to there. Don't forget to drop down the channel selector, and select #ltsp
13:26
<cliebow>
panialex:hAVE YOU RUN LTSPADMIN
13:26
whoops
13:26
<panialex>
nop
13:27
even if i have istaled the k12ltsp i must configure these thinks?
13:28
<cliebow>
i donbt use k12..donr\t know how "out of the box": it is..first try as root to run ltspadmin
13:29
<jammcq>
no, you don't need ltspadmin, if you've installed k12ltsp
13:29
<panialex>
then what should i do?
13:29rjune has joined #ltsp
13:29
<jammcq>
if you've installed k12ltsp, then the server is ready
13:30
next step is find a thin client that is capable of network booting
13:30
<cliebow>
panialex:run netstat -anp|grep ":69"
13:30
<jammcq>
either with PXE or Etherboot
13:30
<panialex>
i have a pc for that, need to download the pxe only
13:31
<jammcq>
you HAVE pxe or you NEED pxe ?
13:31
<panialex>
i need pxe
13:31
i only have to try boot that pc and see if it stards?
13:32
<jammcq>
does it have built-in network interface?
13:32
you may just need to configure the bios for 'Boot from LAN'
13:32moose5435 has joined #ltsp
13:33
<panialex>
no, and i have no pxe net card, i will boot it be floppy
13:34
<jammcq>
then you'll need to go to http://www.rom-o-matic.net
13:34
and generate a boot floppy image
13:34
<panialex>
ok
13:45
how do i see the version of ltsp?
13:46
<jammcq>
look at /opt/ltsp/i386/etc/version
13:50
<panialex>
it says 4.2
13:50
update 3
13:50
<jammcq>
well... there ya go
13:50
but... it could actually be update 4, "someone" forgot to update the version file when I created update 4
13:52g333k has quit IRC
13:52
<cliebow>
heh
13:52
<panialex>
so in the rom o matic page i haw to download for 5.4.2?
13:53g333k has joined #ltsp
13:53
<jammcq>
panialex: that's the 'Etherboot' version. that has nothing to do with the LTSP version

I have a problem with my ubuntu+ltsp installation.. everything work fine, I can get my client booting and it's working perfect... the problem appear when I shutdown the thin client, then try to boot again.. I get a blank screen and nothing in my server log look strange.. someone already saw this kind of problem ?
15:54
<vmlintu>
Arsenick-TC2L: there's nothing coming on the thin client screen, not even BIOS texts?
15:54
<joebaker>
Arsenick-TC2L When that user account is logged out, try running ps aux | grep <username> to see if there are still Gnome processes running on the server.
15:56
<Arsenick-TC2L>
vmlintu: the thin client boot load the kernel the problem seems to be with the Xorg, If I reboot the server everything work fine again.. for one shot ;)

If you kill X with ctrl-alt-backspace, does it help?
16:04
<Arsenick-TC2L>
on the client nothing appear, I tried to restart gdm now
16:04
<vmlintu>
Arsenick-TC2L: btw, are you logging into KDE or Gnome?
16:04
<Arsenick-TC2L>
gnome
16:04
it's working if I restart gdm
16:04
weird
16:04
<vmlintu>
Does restarting gdm in the server help?
16:05rodarvus has left #ltsp
16:05
<Arsenick-TC2L>
yeah it work if I restart gdm on the server
16:05
<vmlintu>
Do you run any KDE applications when you login?
16:05
I've seen this happening when using gdm and login to KDE, it seems to kill gdm

have you tried turning on debugging for gdm?
16:07
also, which ubuntu version are you running?
16:08
<Arsenick-TC2L>
6.10
16:08
I'll try the debug mode
16:08
<vmlintu>
with LTSP 4.2 or the Ubuntu LTSP?
16:10
<Arsenick-TC2L>
I installed the ubuntu package
16:10
<vmlintu>
ok, I haven't tried the 6.10 packages yet
16:11
are you using ldm or gdm with it?
16:11
<Arsenick-TC2L>
and I had a problem during the lstp-build-client I had to delete a file in the chroot the script was failing saying this file already exist.. so deleting this file make the script complete sucessfuly
16:11
it seems to be gdm
16:12
i'll try with ldm
16:12
ldm = encryption with ssh right ?
16:13
<vmlintu>
yes
16:14
<Arsenick-TC2L>
hmm that's weird..
16:14
<vmlintu>
It's quite different from the gdm approach
16:14
I'd guess there's something wrong with gdm as it wouldn't be the first time
16:17
<Arsenick-TC2L>
if I let my thin client boot normaly it's freezing I mean I can't get to a tty but if I go to a tty during the boot then I can see a login in console and if I go to tty7 I see the login page.. lol
16:18
need to smoke a cigaret and think about that ;) brb
16:20
<vmlintu>
what type of thin client is it hardware wise?
16:27
<Arsenick-TC2L>
it's a NTA 6020B

<PMantis>
with bash scripting, anyone know how to echo out (to stdout) the entire contents of stdin... without a read loop to populate a variable?
22:47mwright1 has left #ltsp
23:04
<dberkholz>
PMantis: i'm not sure i understand your goal
23:05
<PMantis>
dberkholz, Wanted to be able to echo the full contents of stdin to another program
23:05
<dberkholz>
the full contents of stdin is a weird phrase to me
23:05
<PMantis>
I think I have a way to do it...
23:05
cat - > /tmp/blah
23:06
well... I can use `while read F` and loop (read only gives one line at a time)... but that seems slow.
23:06
<dberkholz>
so you basically want to cat some file or whatever, and just print the same thing back?
23:07
i think it might be easier to come up with the best way to do something if i actually knew what your real goal is, rather than your suggested implementation...
23:07
<PMantis>
Sort of.
23:07
Ok, whole store....
23:07
story
23:08
I have an entry in /etc aliases, that redirects mail to request tracker
23:08
I wrote a shell script to go in the middle... read the "From" line of the email, then decide on the parameters that i'll pass to request tracker
23:09
But with a while read loop in there, I'm concerned about the processing time - especially if someone sends an attachment...
23:09
So, wanted to know if a simply echo could do it. I guess not.
23:09
<dberkholz>
the only thing your shell script cares about is the From line?
23:11
<PMantis>
for decision making yes... but *all* of the email needs to echo (or cat) to request tracker
23:14
<dberkholz>
one option is to toss the mail in a file, then grep it for From and take the first instance
23:14
you're right that bash loops suck
23:14
<PMantis>
heh
23:14
<dberkholz>
you could also try bash-3 regexp matching
23:14
<PMantis>
For that, I might as well use sed
23:15
But no biggie there...
23:15
<dberkholz>
yeah, sed or grep would work fine. bash definitely is not the best way to do the intensive part of it
23:16
you can read the whole file into a variable with something like foo="$(<filename)" and then do something funky with it, but it'll probably still suck more than sed/grep
23:16
<PMantis>
I think 'cat'ing stdin to a file, then 'cat'ing it back to the RT mailgate is the best way...
23:17
Yeah, memory usage!

hi all
23:30
i need help
23:30
how can i use skype on ltsp
23:30
i'm using esd as sound daemon and the sound is not working ...
23:30
can anybody give me a solution???
23:33
<PMantis>
That'll prove to be very difficult
23:34
Sound over a network is not as easy as X over the network
23:35
However, to use Skype, you'd be better off compiling it for use *directly* on the thin client, and have it fire at a local application.
23:35
Then there'll be no issues with sound
23:41
<Barni_>
and can u explain me how to do this???
23:41
or a site where it's explained???
23:42* PMantis looks
23:44
<PMantis>
I haven't done this before, but...
23:45
But you'll need the LBE (LTSP Build Environment)
23:45
Download that from CVS and compile it.
23:45
Then get the source code for the app you want to be local, compile that with the LBE
23:46
Deploy the executable into the /opt/ltsp/i386/usr/bin directory
23:46
Place an icon on the desktop that opens an SSH session back to the thin client that starts the local application.
23:47
Building the LBE : instructions on the wiki at wiki.ltsp.org
23:47
<dberkholz>
if someone can explain wth rc_cleanup() in the ltsp-build-client plugins is supposed to do, that would be helpful
23:47
<PMantis>
dberkholz, Ubuntu?
23:47
<dberkholz>
i don't know this weird sysv init brokenness
23:47
PMantis: sure, or debian
23:47
<PMantis>
Or should I say, Edubuntu?
23:48
<dberkholz>
since ubuntu uses the debian function, in ../Debian/000-basic-configuration
23:49
<PMantis>
Sure... but the ltsp-build-client is for the MueCow implementation, and I'm only aware of that being on Ubuntu... comes standard in Edubuntu, for example.
23:49
<dberkholz>
it's in debian too..
23:49
<PMantis>
If so, then ogra is a perfect person to talk about that.
23:49
<dberkholz>
unstable or thereabouts
23:49
<PMantis>
Ahh, didn't know that.
23:56
<dberkholz>
anyway, it just doesn't make sense
23:56
they call these variables whitelists, then from what i can tell they blacklist 'em
23:59
<PMantis>
hah, fun
