I have a 64 bit ltsp server and I generated 32 bit client image. When I boot the client with gpxe, I get an error "Failed to connect to NBD server"
02:37
NBD server is running ont he server machine
02:41
<muppis>
Try catch does client try to connect and which port. Deafult should be 2000, but sometimes (when arch differs) hits wrong port.
02:42
<no_mind>
muppis: I tried connecting to nbd-server from client using this command "nbd-client 192.168.2.4 /dev/nbd0 -persist" . I get an error "nbd0: unknown partition table"
02:42
also
02:43
the gpxe is not autobooting
02:43
I have to manually specify kernel, initrd and boot at gpxe command line
02:43
I am using usb image from rom-o-matic/etherboot
02:45
<muppis>
Sounds like you got somehow corrupted imade.
02:45
image..

Hi - I am writing a short Finnish Howto on Ubuntu LTSP installation. Is there an up-to-date version of hw requirements? I have seen several instances of calculation schemes but I do not know which I should refer to.
06:33
Would this be the best one? https://help.ubuntu.com/community/Installation/SystemRequirements#LTSP%20thin-client%20computers

Good morning from Brazil, can any body help me to run a LTSP with SIP local softphone and local audio?
09:33
ive tried many things without sucess, a can register, make calls, but the sound quality is poor, kinda metalic, ive tried with a livecd on the same pc and the sound work greate
09:37korcan has joined #ltsp

<muppis>
Does software run locallly or server?
09:38poff has quit IRC
09:41_UsUrPeR_ has joined #ltsp
09:41
<Mateus>
I tryng locally
09:42
will be 30 stations, then i think the best setup for voip is run softphone locally
09:52johnny has left #ltsp
09:56
<Gadi>
Mateus: is the audio out/in using alsa or pulse?
09:57otavio has joined #ltsp
09:58
<Mateus>
alsa
10:02
<Gadi>
is the out bad or the in bad?
10:02korcan has quit IRC
10:03
<Gadi>
ie. (record or playback)?
10:03korcan has joined #ltsp
10:03
<Mateus>
both, only in the softphone, others prograns running on server the sounds perfect
10:04
<Gadi>
can you set the softphone to use pulse?
10:05
<Mateus>
pulse works with program running locally?
10:05
<Gadi>
it should, I believe
10:06
<Mateus>
ok, I'll try after my lunch, thanks a lot for your attention
10:06
<Gadi>
alternatively, you can try installing pulseaudio-utils in the chroot and run: pasuspender -- /path/to/softphone
10:06
<Mateus>
hm ok
10:06
<Gadi>
actually, I think someone else here with a softphone wound up doing that
10:07
<Mateus>
good, thanks again
10:07
bye, i'll come back later...

Is there anyone around who can help me figure out why two of my clients cannot gogin?
11:20
Login. Its only two of my twelve machines.
11:20
<Kyle__>
sidartha: Are you sure they're booting all the way? Can you ssh to them, or login using a local account?
11:21vagrantc has joined #ltsp
11:21
<sidartha>
I get to the LDM LoGIN SCreen , But no matter what user I use, it goes back to the login screen
11:21
<alkisg>
sidartha: it might be a compiz problem, do you see an entry in /var/log/auth.log ?
11:28
<sidartha>
i dont see anything about compiz. Here is a section of the log

<alkisg>
sidartha: is this from a problematic client? "Sep 13 12:27:52 ubuntuARTROOM-LTSP sshd[813]: Accepted password for blue from 192.168.0.30 port 35267 ssh2"
11:33
I mean, if it accepts the password, then it's a session problem, possibly compiz
11:33
!compiz
11:33
<ltspbot>
alkisg: "compiz" :: if compiz is giving you problems, one way to disable it for all users is: sudo gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/session/required_components/windowmanager metacity
11:35
<sidartha>
ill try that
11:38
that did it.. Thanks again
11:43otavio has quit IRC
11:43
<sidartha>
alright I have another problem.

I installed Chromium in chroot and have it running as a local app, however whenever I reboot the machine I have to set it up as if I opened it again for the first time.
11:44
Its not saving its session
11:47
<alkisg>
AFAIK chromium doesn't work with sshfs (the default with localapps), it needs nfs
11:50otavio has joined #ltsp
11:50
<sidartha>
I changed include this string in LTS.CONF [NFS_HOME=/home] Do I have to add another directory for it to save its session?
11:52
<alkisg>
No, but did you export /home from your server?
11:52
If you didn't, then it still uses sshfs...
11:52pmatulis has joined #ltsp
11:52
<alkisg>
(and, you didn't add the square brackets there, did you?)
11:54
<sidartha>
no square brackets. How do I export /home?
11:57pmatulis has quit IRC

<Kyle__>
sidartha: Be careful if you use nfs off of an ubuntu server: their rcp.stad is buggy.
11:58bobby_C has joined #ltsp
11:59
<sidartha>
Sounds Like I should just stick with Firefox? Know of a way to sync extensions, bookmarks?
12:00
<alkisg>
sudo -i
12:00
echo '/home *(rw,sync,no_subtree_check)' >> /etc/exports
12:00
exportfs -ra
12:01
That exports /home...
12:01
And I'm also using NFS_HOME_OPTIONS=defaults,nolock in lts.conf to bypass that statd problem
12:02
(nolock ==> users shouldn't open the same file for writing simultaneously)
12:02
(it's only a work around, and not a good one, but it works for me)
12:03
Ah, and sudo apt-get install nfs-kernel-server
12:03
<sidartha>
alkisg: the reason I am using chromium is because of the sync ability. Do you think I should stay with firefox, and just install addons individualy?
12:03
<alkisg>
How much ram on your clients?
12:04
<sidartha>
512
12:04
<alkisg>
Both would do, it's a personal choice...
12:04
<sidartha>
ok Thanks
12:04mistik1 has joined #ltsp
12:07Gadi has left #ltsp
12:18
<sidartha>
alkisg: I expoted /home and added NFS_HOME_OPTIONS=defaults, but chromium is still not saving sessions, How can I chech if NFS /home is set up?
12:19
<alkisg>
!localxterm
12:19
<ltspbot>
alkisg: "localxterm" :: while sitting on a thin client, open a gnome terminal. In that, run: ltsp-localapps xterm. An xterm will open. That xterm runs locally, so any commands you enter there are executed directly on the client.
12:19
<alkisg>
sidartha: on a localxterm, run `mounts` and see if /home is mounted with nfs
12:19
Erm, mount, not mounts
12:22
<sidartha>
I dont see /home listed
12:23
<alkisg>
So it's not mounted with nfs
12:24
$ cat /var/lib/nfs/etab
12:24
/home *(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534)
12:25
This tells you if it's exported on the server
12:26
<sidartha>
I think I made a duplicat /home export? How can I delete one of them.
12:27
it is exported to the server
12:27
<alkisg>
sudo gedit /etc/exports
12:27
fix it, and run sudo exportfs -ra
12:29otavio has quit IRC
12:29otavio has joined #ltsp
12:30otavio has joined #ltsp
12:33
<sidartha>
ok I fixed it and ran sudo exportfs -ra, and it says /home *(rw,sync,wdelay,hide,nocrossmnt,secure,root_squash,no_all_squash,no_subtree_check,secure_locks,acl,anonuid=65534,anongid=65534)
12:33
But It stiil not mounting on local
12:34
<alkisg>
Can you paste your lts.conf? Also, is this Lucid?
12:37
<sidartha>
http://pastebin.com/spam.php?i=iaWdrXC0 This is Lucid
12:39
<alkisg>
What does `status statd` tell you on the server?
12:39
Also, remove /home from LOCAL_APPS_EXTRAMOUNTS
12:40
(and, until you get it right, you may want to try: NFS_HOME_OPTIONS=defaults,nolock)
12:41
(a client reboot is needed - logoff won't do it)
12:42
<sidartha>
statd start/running, process 3634
12:44
and still not mounting
12:44
made lts.conf changes
12:44
<alkisg>
Try getting a local root screen on the client and mounting /home somewhere else manually:
12:45
In lts.conf, add:
12:45
SCREEN_02=shell
12:45
SCREEN_07=ldm
12:45
Reboot client, and at ldm press alt+ctrl+f2, you'll get a local root console
12:45
mkdir /tmp/home
12:45
mount -t nfs server:/home /tmp/home
12:51
<sidartha>
wron fs type....error
12:51
wrong fs type
12:53
<vagrantc>
is nfs-common installed in the chroot?
12:53
<sidartha>
no
12:54
installing it know
12:54
now
12:55
<alkisg>
(remember to run ltsp-update-image)
12:57
<vagrantc>
alkisg: nfs-common is needed, yes?
12:58
<alkisg>
On my notes in https://help.ubuntu.com/community/UbuntuLTSP/FatClients I have nfs-client, let me see in my sch-scripts code...
13:00
You're right, nfs-client is obsolete, I should change that to nfs-common, thanks :)
13:11
<sidartha>
bingo that worked.. Thank Both Of you.

Hi, I was here a few hours ago asking about hp tf5700 video driver. The card states (From lspci) ATI Rage LX, the spec sheet says ati rage lx. its an 8mb card. I dont know what driver i am currently using but i have managed to get better resoultion by copying the entire mode line from one I found elsewhere. I dont understand the mode line so i cannot tell if it is the good thing to do or not.
15:13
<thunsucker>
anyone have a link to modify the rdesktop screens script to modify the refresh time
15:14
<alkisg>
cole2: a mode line works, but XRANDR_MODE_0 doesn't?
15:16
<cole2>
Through all my Reading I have never seen XRANDR_MODE_0 how do I use this?
15:16
<alkisg>
!lts.conf
15:16
<ltspbot>
alkisg: "lts.conf" :: http://manpages.ubuntu.com/lts.conf
15:17
<alkisg>
See the docs :)
15:17
XRANDR_MODE_0=1024x768
15:22
Could someone tell me the correct english word for this? Suppose that a school has 60 first-grade students, and they are divided into 3 groups of 20, and each group has its own classroom. What are those groups called? Classes?
15:23
<jammcq>
sounds good to me
15:23
<alkisg>
Thanks!
15:24
<thunsucker>
alkisg: have you ever heard anything the refresh rate of the rdesktop script?
15:24
<alkisg>
What refresh rate? Of the screen, e.g. 60Hz?
15:25
<cole2>
Thanks, I dont know why i have never seen the whole section before. I will do some reading and try it out a little later on.
15:32paal- has joined #ltsp
15:49
<thunsucker>
alkisg: no the rdesktop client waits a few minutes then "refreshes"
15:49
<alkisg>
thunsucker: that's not related to the script
15:49
The windows server closes the connection because it assumes it's idle
15:49
You can change that in the windows server settings. I found the setting once, but never again :D
15:50
....so people here make a loop in the rdesktop script so that X doesn't die on each disconnection...
15:50
<thunsucker>
gotcha
15:51
logonui.exe is putting a heavy load on our ts server cpu's
