good morning everyone
02:00
for ubuntu 10.04, what packages do i need to install in the chroot in order for sound to work in totem as a local app?
02:01gnunux has joined #ltsp
02:02
<muppis>
jimjimovich, sound should work out of box, but how about codecs?
02:02
<jimjimovich>
muppis: sound works for apps running on the server, but not for local apps (even the volume control is gone in totem)
02:03
<muppis>
jimjimovich, how about other local apps, like FF/Flash?
02:03
I am aiming is it really totem or system problem.
02:04
<jimjimovich>
looks like totem, because sound is working in local Chrome
02:05
<muppis>
Ok..
02:06
<jimjimovich>
trying to install all totem related packages that are installed on the server
02:08
<muppis>
Try run gstreamer-properties.
02:09
<gnunux>
hi
02:11
<jimjimovich>
muppis: gstreamer-properties doesn't exist in the chroot ...
02:11mistik1 has quit IRC
02:15
<muppis>
jimjimovich, it's in gnome-media-common package, I think
02:15
Sorry, gnome-media
02:18mistik1 has joined #ltsp
02:19
<johnny>
jimjimovich, it's not recommended to use totem
02:19
it won't work right because of gconf
02:20
you should stick with vlc or some mplayer frontend until all that stuff is ported to gsettings
02:20vagrantc has joined #ltsp
02:20
<johnny>
i'm not sure when that's going to happen sadly
02:20
hopefully by 11.04 ...
02:20
<jimjimovich>
totem worked fine when i was using a fat-client chroot to boot my thin clients ... strange
02:20
<johnny>
yes
02:21
as local?
02:21
<jimjimovich>
yeah
02:21
<johnny>
are you sure it was running local?
02:21
it works fine in a real fat client
02:21
<jimjimovich>
100% sure
02:21
local app on a thin client
02:21
<johnny>
hmm, well i'm just going by what alkisg said
02:21
<jimjimovich>
we were even watching dvds on it
02:21
<johnny>
maybe they did fix the gconf issue
02:21
then whats the problem.. just install all the deps
02:22
<jimjimovich>
i just don't know what debs to install to make sound work
02:23
<johnny>
all the deps of totem right?
02:23
<jimjimovich>
muppis: when i run gstreamer-properties on the thin client, the video tests work but the audio tests say "Could not open resource for writing"
02:23
yeah, all totem debs, all gstreamer (I think)
02:24
totem works, just no sound
02:24
<johnny>
just use the fat client chroot then
02:24
it requires most of the same stuff
02:24
and then uninstall openoffice or whtaever is large

Hello, I am using ubuntu 10.04 and I was trying to build clients but I notice I must have internet connection....Is it possible to do this step while off line ?
02:41
<vagrantc>
if you have a CD image with all the appropriate packages...
02:43
<Appiah>
?
02:43
<DraZoro>
Yes I have a cd image
02:44
<Appiah>

<DraZoro>
Appiah ...Thanks ...vagrantc thanks
02:45
I have already installed ltsp-server on my box ....
02:45vagrantc has quit IRC
02:45
<Appiah>
ltsp-build-client --mirror
02:46
<DraZoro>
So I can direct it to my local files ....? Appiah
02:46* DraZoro checks man ltsp-build-client
02:46
<jimjimovich>
hey guys, got totem working, just needed to install the package "gstreamer0.10-pulseaudio" :)
02:48
<Appiah>
DraZoro never have before so I dont know
02:48
worst case , start a webserver , copy the files from the cd
02:49
and mirror localhost :)
02:49
<DraZoro>
Appiah: I believe that is what I was looking for all alone ....just checked the manual I try it
02:49
Appiah : It also support file:// so not need for Apache
02:49
<Appiah>
good
02:50
<DraZoro>
I will copy the files and direct that ltsp to that location ...Thanks a million times once again
02:52
Ok bye guys let me try once again

hi all, I am new here and have a question
03:05
allright to ask?
03:06
<muppis>
!ask
03:06
<ltspbot>
muppis: "ask" :: Don't ask to ask a question, simply ask it, and if someone knows the answer, they'll respond. Please hang around for at least 15 minutes after asking a question, as not everybody constantly monitors the channel.
03:07
<feinbein_fred>
OK, thanks. I have a ltsp-thinclient with two monitors and my problem is that the ldm-greeter sits right on the border between the two.
03:07
Anyone knows how to get it to sit on the left-hand monitor?
03:09
<muppis>
feinbein_fred, have read this? http://www.mail-archive.com/ltsp-discuss@lists.sourceforge.net/msg26293.html
03:10
<feinbein_fred>
will do and come back, thanks
03:16
muppis, I have the dual-monitor setup fine. It is the greeter of ldm that bothers me. would not /opt/ltsp/i386/usr/share/ldm/themes/ltsp/greeter-gtkrc be the file to look at? Instead of xorg.conf
03:20
<elias_a>
Hello dudes - we are trying to figure out how to make Windows 2003 server DHCP to give a fixed IP address to a LTSP server.
03:20
Any hints on how to do that?
03:23
<muppis>
feinbein_fred, sounds better place.
03:26
elias_a, heh.. that could be problem..
03:27
<elias_a>
muppis: No - I already found a howto for that.
03:27
<muppis>
Whoa :)
03:28
<elias_a>
Now the problem is that we are looking the services of servers in a small town in order to find where the DCHP server is :)
03:28
<Appiah>
?
03:28
you dont know where the DHCPservers are?
03:29
<elias_a>
Appiah: Actually not yet. We are waiting for the chap responsible for the servers to arrive :)
03:29
<Appiah>
:)
03:29
<elias_a>
We have a LTSP workshop. Trying to live with the existing infrastructure ;-)
03:30
<alkisg>
You can temporarily disable ssh host checking so that the ltsp server works with a dynamic ip :)

<feinbein_fred>
elias_a, have you got admin access to the 2003 server? then its pretty straight forward if you know your macaddress

04:02
<feinbein_fred>
good, you may wanna set the next-server option in the dhcp-server as well
04:02
<elias_a>
feinbein_fred: Actually I was so lost with the 2003 server as it did not act as a DHCP server after all :)
04:02
Misinformation :)
04:03
<feinbein_fred>
elias_a: so it was the router?
04:03
<elias_a>
We found the right guy to give us fixed addresses from the router.

<elias_a>
Hey - is it possible to make a LTSP server to retrieve the IP addresses from a DHCP server elsewhere in the local network?
05:56
<muppis>
Sure.
05:57
Just make sure that other one can also server PXE information.
05:57
I used DD-WRT wlan router to handle DHCP.
06:01
<elias_a>
muppis: We also are setting up a LTSP server in a network where all the PCs get their IPs with DHCP.
06:02
I am thinking about getting the IPs for the LTSP clients from the same DHCP during the login process.
06:04
<muppis>
elias_a, those clients that do not need PXE info just ignores it.
06:05
Thin client actually does two dhcp query. While starting bootprogress and while loading kernel.
06:06
But now need to go.

Is it possible to make a LTSP cluster with 2 NIC server setup?
08:41
We hit our heads into a wall when trying to figure out what we don't understand...
08:43
How does one alter this https://www.ltsp-cluster.org/documentation/howto/openvz-setup#Host_installation so that it could be used with the 2 NIC setup?
08:46
<Appiah>
are you planing on running it on openvz?
08:46
will all your ltsp servers have 2 nics?
08:47
is it for bonding/balance?
08:47
<elias_a>
Appiah: No, we are going to run it it in servers.
08:48
We can choose between using 1 or 2 NICs.
08:48
<Appiah>
which server/what servers will have 2 nics
08:48
will they be connected to the same network?
08:48
etc etc
08:48
Short answer : Yes LTSP and LTSP-cluster can work on multiple nics there's no limitation
08:49
<elias_a>
The problem here to solve is that there already is a DHCP server in the network we are going to use.
08:49
<Appiah>
all depends on your infrastructure and not ltsp itself
08:49
or ltsp-cluster
08:49
<elias_a>
And we should authenticate using an already existing LDAP server.
08:49
<Appiah>
either put all your ltsp dhcp stuff into the existing DHCP server or replace the DHCP server
08:49
or make them co-exist
08:49
<elias_a>
Appiah: OK. Thank you. Guess we have a lot of reading and thinking to do ;-)
08:51ogra_ac has quit IRC

Quite interesting situation to jump into a small commune where the infrastructure "just works" and we run into digging different bits of information about it...
08:55
<Appiah>
tell me about it...
08:59
<elias_a>
BTW - this flood of stupid questions is generated by me and asmok - we are running a workshop in a small commune, Vörå-Maxmo in Finland.
09:00
<Appiah>
oh
09:00
were you by any chance in Umeå, Sweden on a open source conferance?
09:02
<elias_a>
Well - what we are trying to setup is a LTSP cluster that consists of 2 servers. We should authenticate using a LDAP server (no prob - have good instructions) and the LTSP system should happily live together with the existing network (Windows PC's).
09:02
Appiah: No - we were not there but some of the dudes who participate this workshop were.
09:02
I will ask tomorrow.
09:03
<Appiah>
ah , then i remeber correctly. I was there when one of our clients presented their LTSP (that we helped buil)
09:03
d
09:04
<elias_a>
Which one was it?
09:04
Appiah: Are you Norwegian?
09:24johnny has left #ltsp

09:41
<Appiah>
Umeå :)
09:42
http://openkvarken.fi/
09:42
umm is that the workshop?
09:43
<elias_a>
Yup.
09:45
Is there a difference between getting an address with DCHP when booting PXE boot compared to the situation where there's a running OS and a network cable is plugged in?
09:46
<Appiah>
same MAC so no
09:46
<elias_a>
Strange...
09:46
There seems to be something really strange here, then...
09:47
<Appiah>
on the same computer you're getting different results?
09:47
<elias_a>
I'll check once more. Just a minuta.
09:47
minute...
09:50
Appiah: Yes: The same machine, same NIC does get an IP when running Ubuntu 10.10. but not when I try to boot it using PXE.
09:51
<Appiah>
is the PXE boot even working?
09:51
<elias_a>
No, but shouldn't we get an address in spite of that?
09:51leio has quit IRC
09:52
<Appiah>
well yes but if the IP is different check your DHCP server
09:52
does it even lease ?
09:52leio has joined #ltsp
09:52
<elias_a>
We have no access to the DHCP server. It is a Linux box but we cannot access it.
09:53
<Appiah>
well if you dont know the configuration of the DHCP server ...
09:53
<elias_a>
Yes. That is the problem.
09:53
<Appiah>
well then I have no idea...
09:54
so if you PXE boot you got x.x.x.10 and when you're in OS and plug in a cable you get x.x.x.12 ?
09:54
<elias_a>
Have to tackle this problem tomorrow when we get the guy who maintains the DHCP server.
09:55
Appiah: We are trying to get this to avoid using 2 nic's now https://help.ubuntu.com/community/UbuntuLTSP/ProxyDHCP
10:00
This is because we do not how to configure the cluster balancing to work with 2 nic setup.
10:01
<Appiah>
so what's the problem?
10:01
I use proxyDHCP in our office for my LTSP-Demo
10:02bobby_C has quit IRC
10:02
<elias_a>
We got pretty far but for some reason the application server is searched from the IP address space of the thin clients, not the addresses that we have for the server(s) in the commune network.
10:02
<Appiah>
you dont use static IP's for the application servers?
10:02
<elias_a>
Yes we do.
10:03
<Appiah>
I dont see the issue. Your clients can boot ?
10:03
<elias_a>
They have been dedicated to the servers by the guy running the DCHP server and network connectivity works OK:
10:06
Just a minute - we will replicate the problem.
10:08
reproduce, I meant.

Thin client shows the following: "Application server: 192.168.0.254"
10:09dgroos has left #ltsp

This is really odd because it should be 10.56.0.220.

<ltspbot>
Gadi: stgraber was last seen in #ltsp 4 days, 18 hours, 28 minutes, and 49 seconds ago: <stgraber> if you have any experience with vz, I'd suggest it as you'd be able to have your different services isolated and both application servers to be absolutely identical (you could then just copy the VZ from one box to the other)
11:12johnny has joined #ltsp
11:24asmok has joined #ltsp

<stgraber>
Gadi: I'm here ;) just not speaking much on #ltsp lately
11:28
<asmok>
stgraber: I do use ltsp-cluster with one nic per server (root and two app servers). Is it possible easily to use two nics per server traditional ltsp-way?
11:28
Now tc info says: Application server: 192.168.0.254?
11:31
<Gadi>
asmok: I have 2-nic app servers
11:31
I think I only had to change lbaconfig.xml on the app servers
11:31
to retrieve the IP from eth1
11:31
rather than eth0
11:31
<asmok>
here are my config files:
11:32
http://arkki.info/lbsconfig.xml
11:33
http://arkki.info/dhcpd.conf
11:33
ltsp-cluster-control.config.php
11:35
do you have dhcpd in ltsp-root server or out somewhere?
11:37
<Gadi>
the app server has an lbaconfig.xml
11:38
<asmok>
yes, i check that tomorrow
11:38
<stgraber>
the default lbaconfig.xml uses the IP address of the interface used to go to the internet (default gateway), if you want it to use another one, update the command in lbaconfig.xml
11:44
<asmok>
show me please correct lbaconfig.xml- when app1 eth1 is 192.168.0.254 - and, is app2 eth1 192.168.0.253?
11:45
<elias_a>
asmok: These are of course the addresses of the LTSP client side nic, right? :)
11:46
(They sure are as we are sipping beer next to each other on a hotel sofa.) ;-)
11:46
<asmok>
Yep server sides are in this case 10.56.0.220 and 10.56.0.221
11:47
<Gadi>
asmok: on line 25, I use: <command>ip addr show dev eth1|grep 'inet '|sed -e "s/^.*inet //" -e "s/\/.*$//"</command>
11:52
<asmok>
you mean this original line: <command>ip addr show | grep "inet " | grep -v 127.0.0.1 | sed "s/.*inet //" | sed "s/\/.*//"</command>
