00:10
<vishal_>
ya i have downloaded the file
00:10
<alkisg>
Where did you put it?
00:12
<vishal_>
l/usr/share/ltsp
00:13
<alkisg>
Don't put it there, put it in the chroot
00:13
<vishal_>
tell me how to put and command
00:13
so that it is easy for me
00:14
<alkisg>
In /opt/ltsp/i386/usr/share/ltsp/
00:15
<vishal_>
ya i put over there only
00:15
files are there
00:15
<alkisg>
And then what did you do?
00:16
<vishal_>
noting i restart dhcp and booted client
00:17
<alkisg>
You need to run ltsp-update-image
00:17
<vishal_>
ya i have done that
00:18
<alkisg>
Is the script executable?
00:18
<vishal_>
yes

Run this, what's the output? ls -l /opt/ltsp/i386/usr/share/ltsp/kioskSession
00:19
<vishal_>
-rwxr-xr-x 1 root root 12412 2011-02-24 16:54 /opt/ltsp/i386/usr/share/ltsp/kioskSession
00:19
this is the output
00:20
<alkisg>
It's too big
00:20
The correct size is 671 bytes
00:20
You didn't download the correct file
00:21
<vishal_>
tell me the command through which i ca dowload this file
00:21
should i remove this file
00:21
<alkisg>
Just open the link with your browser
00:21
The link to the file is mentioned to the bug report
00:24
<vishal_>
when i clieck on that link it open one file
00:24
shoud i copy that file from there
00:24
because there is no dowload option
00:25
<alkisg>
There's a 'download file' to the right
00:27
<vishal_>
when i clienk on download file it is giving me the download for ubuntu server
00:28
shoud i manually copy that file ad copt it
00:29
<alkisg>
No
00:29
Here is the link you should click: http://bazaar.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk/download/head:/kiosksession-20100126175421-j3qe71nsxfopg3p6-1/kioskSession
00:30
<vishal_>
the u tell me how to do that
00:30
<alkisg>
That's the 'download file' link
00:30
I don't know why you didn't see it
00:30
<vishal_>
ya now i got that file
00:30
ow what to do tell me
00:30
<alkisg>
I don't have time to tell you how to copy files
00:30
Just copy it to its place and run ltsp-update-image
00:31
It's just basic shell commands...
00:31
and basic browser usage...
00:31
I need to write a paper, bbl
00:32
If you want, write a comment to the bug report
00:32
Saying that you experienced the bug and that you'd like a backported fix for it
00:38
<vishal_>

if m going to rum ltsp as kiosk mode
02:31
do i need to install firefox on the same machine or it will take auto when i run this command
02:34
<alkisg>
Firefox gets automatically installed in the chroot
02:47dobber has joined #ltsp

<navn>
is it neccessary to insall ltsp on server or we can install it on desktop version also
03:11
<alkisg>
Which distro?
03:12
<navn>
ubuntu
03:12
10.04
03:12
<alkisg>
You can install it in any variant
03:13
<navn>
k i can install ltsp on 10.04 server also or desktop also no matter right
03:37
<alkisg>
Usually the alternate cd is used. Then the desktop. The server is not usually used.
03:37
As the server CD lacks a desktop, which is required for clients - maybe not for kiosk though
03:39
<muppis>
At first time I used server CD. First install ltsp, then desktop. Worked fine.
03:40
<alkisg>
Maybe for the kiosk a desktop isn't even needed on the server. Just X/firefox on the chroot.
03:42
<muppis>
Hope so.
03:43
<alkisg>
muppis: was it you asking about converting a local installation to ltsp yesterday?
03:44
<muppis>
alkisg, yes, but I got problem fixed other way round. But if you got an answer, please tell.
03:45
<alkisg>
Sure the answer is "nope - unless you manually do what the ltsp-build-client plugins do" :)
03:45
But you can convert it to a *non-ltsp* fat client easily
03:45
(somewhat easily)
03:46
<muppis>
diskeless-client, so to speak.

question about printers
04:20
i have one central cups server running on 192.168.1.1 in my network
04:20
my tc server is at ip 192.168.1.6
04:20
<navn>
hey i have done all the trouble shooting which is written in bugs
04:20
but user is not booting withh firefox
04:20
tell me what i do
04:20
<zamba>
the tcs should use the same printers defined on 192.168.1.1.. how should i set up this? point all the tcs to the cups server at 192.168.1.1 or set up cups on 192.168.1.6 and then just forward requests to 192.168.1.1?
04:21
i've tried the latter, but am unable to print
04:21
Processing - "Unable to get printer status (Bad Request)!"
04:24
<navn>
ltsp with kiosk mode is not working with ubuntu 10.04
04:32
<alkisg>
navn: are you vishal from before?
04:32
zamba: do you have localapps involved?
04:32
If not, then it's just plain printer sharing, you share your cups printer to the ltsp server, nothing more...
04:34
<navn>
yes, we are friends doing the same project
04:36
now what we did , we have installed 10.04 server on that ltsp , but noting is working fine
04:36
<zamba>
alkisg: i don't at the moment, but i may in time
04:36
<alkisg>
navn: just follow what's written on the bug report
04:36
There's no other source of information
04:36
If you didn't manage to get it working, comment it on the bug report
04:36
<zamba>
alkisg: so how should i set up the printer sharing?
04:37
alkisg: is it enough with just one cups server running at the central location?
04:37
<alkisg>
zamba: sure
04:37
<zamba>
alkisg: but how do the tc server know about it?
04:37
<alkisg>
On the cups server you check "publish this printer on the network"
04:38
There's nothing ltsp-specific about it, usual cups sharing
04:38dlezcano has quit IRC
04:39
<zamba>
alkisg: that's all i need to do?
04:39
alkisg: i don't have to set up the printers on the tc server?
04:39
<alkisg>
Right, and you might also need to check "use network printers" on the ltsp server
04:39
<zamba>
alkisg: where do i do that?
04:40
<alkisg>
zamba: http://reformedmusings.files.wordpress.com/2009/11/cups-server-settings.png
04:40
It's not ltsp related, you can find it at the first result on google :)
04:40
<zamba>
but can i then just remove the cups installation on the tc server?
04:40
<alkisg>
cups is preinstalled
04:41
<zamba>
but i can just remove it? isn't that what you're saying?
04:41
<alkisg>
You need the cups client to access the cups server
04:41
So no
04:41
<zamba>
ok
04:41
<alkisg>
Not sure if you can remove "cups" and keep "cups-client"
04:41
<zamba>
but i can remove all printers added on the tc cups and just tick the "show printers shared by other systems"?
04:42
<alkisg>
Yes
04:42
<zamba>
sweet
04:42
<alkisg>
For local apps it's a different story, leave it for when you need it
04:42
You might install cups in the chroot, or you can use jetpipe, whatever you want
04:45
<zamba>
argh, i hate the ACL stuff for cups

hi all
06:06
i install ltsp in fedora 14 and it is work good when all client there are in a same switch
06:06
but i have 4 switch ,which each switch have subnet mask and special range address for client connected to this switch
06:07
and client in other switch can not access to ltsp server and boot from it
06:08
alkisg, hi
06:08
<sep>
mahdi_ja, switches does not have ip'r or range's except for management. ; do you have 4 network cards on your machine? each conencted to a different switch ?
06:09
<mahdi_ja>
sep, no i must have 4 nic for my switch ?
06:09
<sep>
mahdi_ja, how are the switches conencted to the server ?
06:10
<mahdi_ja>
sep, with core switch
06:10
<sep>
adn when you say that the switch have a different subnet mask and range what are you talking about ?
06:11
all devices in the same network should have the same subnet mask. and the range (dhcp range) are set on the ltsp server, and does not relate to what switch a device is connected to
06:11
well set on the dhcp server atlest. not nessecarily the ltsp server
06:11
<mahdi_ja>
sep, for test i add a client and test ltsp,test pc is a client of a one switch which connected to the server
06:12
sep, but why i can not connect to the ltsp server
06:14
<alkisg>
mahdi_ja: describe your network topology better. Is it ltsp server <=> core switch <=> 4 other switches <=> clients?
06:15
<sep>
use the client that functions. and test each switch so you know if you have a problem with your network. if that works. check the config for the client that does not work on the ltsp server
06:16
<mahdi_ja>
alkisg, yes
06:16
<alkisg>
And the client works when you connect it where? To the core switch?
06:17
Or is it ltsp server <=> 1 switch, with the working client <=> core switch <=> 3 other switches ?
06:17
<mahdi_ja>
alkisg, but for test i do not user pc behind core switch and user client a pc behind a switch
06:17
<alkisg>
mahdi_ja: I lost you, repeat that sentence without saying the word "not"
06:17
<mahdi_ja>
alkisg, yes in my lan there is a windows dhcp server and the get ip address
06:18
<alkisg>
mahdi_ja: it looks like you have a complicated setup
06:18
You need to describe it a lot better in order to have useful answers
06:18
And also, if you have VLANs on your core switch, mention those too
06:19
<mahdi_ja>
alkisg, i see full document of my lan and go back
06:19
<alkisg>
ok
06:19
<mahdi_ja>
alkisg, thank you
06:29
alkisg, hi again
06:29
alkisg, i have 4 switch with a same subnet mask 255.255.0.0
06:30
and i with 6 vlan
06:31
<alkisg>
I think fedora uses duplicate IPs for the ltsp server
06:31
One the real one, e.g. 10.160.31.10, and one for the ethernet alias, e.g. eth0:1, e.g. 192.168.0.1
06:31
So you need to configure your VLANs to allow that traffic
06:31
I don't know the details, I've never used fedora
06:32
<mahdi_ja>
fedora create a virtual bridge for ltsp and the connect it to the network card
06:33
for example brctl addif ltspbr0 eth1
06:33
default range ip address is 172.31.100.0/24
06:33
<alkisg>
There's only 1 physical IP there, isn't it?
06:33
So it uses an ethernet alias to provide a virtual second one?
06:33
And then it bridges them together?
06:34
*1 physical NIC, sorry
06:34
<mahdi_ja>
two nic one for client and another for connect to internet (for example)
06:34
<alkisg>
OK anyway I don't know how fedora handles its network
06:35
Just make sure that the traffic can reach your clients
06:35
<mahdi_ja>
alkisg, thank you.

Sorry, this bridging/aliases etc is fedora specific, I don't know the exact setup

<MorningSon>
is there any way to specify how ltsp-build-client does it's job?
17:09
like i want a minimal desktop environment should i build it the way i want it on the client then run ltsp-build-client?
17:10
because using the lucid lynx desktop is kind of overkill for what i'm after
17:10
<abeehc>
i suppose you could pull that off with a fat client
17:11
thin clients or fat clients?
17:11
<MorningSon>
really i want a fat client setup since the server isn't really able to handle the 30 or so instances of firefox i'll need running
17:12
<abeehc>
https://help.ubuntu.com/community/UbuntuLTSP/FatClients
17:12
ff is a bugger; my server handles a good 25 and it's not exactly a monster
17:12
but you'll notice in the ltsp-build-client.conf it instructs you to create
17:12
<MorningSon>
maybe chromium might be better
17:13
<abeehc>
you can speficiy the FAT_CLIENT_DESKTOPS param

i think you can use most of the meta packages like xubuntu-desktop

I'm pretty sure chromium is much lighter; but I've not been brave enough to take a run at it
17:13
ff isn't so bad; mostly flash is what rips my server
17:14
<MorningSon>
yeah i just wish i had more fine tuning abilities when builing an image
17:15
<abeehc>
the script does accept some arguments but not too many
17:15
<MorningSon>
i don't like that i have to use a script to go and download a bunch of what is essentially bloat for what i need it for
17:15
i left the server at work building a --kiosk image so we'll see how that works
17:15
<abeehc>
this may not be the solution for you
17:16
and in any case apt-proxy is nice
17:18
<MorningSon>
i've been having the wierdest problems with thin client images though, they boot up and log in fine but it looks like they aren't interacting with the desktop at all, but if i use ctrl+alt+left and right to swich between desktops the screens get "refreshed" and what I was trying to do pops u[
17:18
ip
17:18
up
17:19
so for instance i'll hit the firefox button, looks like nothing happened, switch to desk2 then back to desk1 and ff is waiting for me

have you disabled compiz yet?
17:35
!compiz

<ltspbot>
abeehc: "compiz" :: the default window manager in gnome is gnome-wm, which automatically chooses compiz if it thinks that the card supports it. Compiz is causing login problems to some clients (LP #673072). To disable it, see !disable_compiz. To restore it, see !restore_compiz
