If I test a new LTSP server installation with 1 PC, should it be connected to the server through a switch or is it possible to test connecting the cable directly to the client PC?
01:32
<cyberorg>
elias_a, you can test it directly
01:35
<elias_a>
cyberorg: Thanks - don't I even need a crossed pair cable?
01:35
I have a new installation and it does not give an address to the client - that's why I am asking.
01:36
<cyberorg>
elias_a, nopes, not since many years :)
01:37
elias_a, check logs, make sure dhcp server is setup properly
01:37
<elias_a>
cyberorg: Will do - thanks!

About ltsp-cluster in Karmic
01:49
If I try to install ltsp-cluster-lbaserver I got this
01:50
update-rc.d: warning: ltsp-cluster-lbserver stop runlevel arguments (0 1 6) do not match LSB Default-Stop values (1) [fail]
01:51
* Starting ltsp-cluster-lbserver...
01:51
invoke-rc.d: initscript ltsp-cluster-lbserver, action "start" failed.
01:52
So should I start testing with Hardy or Jaunty + ltsp-cluster-team's PPA
01:52
or should I wait for final Karmic?
01:53
I use KVM based server and real thin client for testing
01:54
My KVM based Karmic LTSP server works just fine
01:55
and now I like to do some first testing with ltsp-cluster on KVM
02:00
Well, I go for Jaunty + PPA, bye

Hi All. I have a strange problem. Ltsp client boots fast and successfully when I use dlink DES-1024D switch for network. The clents boots slower and stops after the progress bar becomes white when I use HP ProCurve Switch 1700-24.
03:54
I think the problem is in eth0 auto-negotiation. How I can configure eth0 (disable auto-negotiation, sets 100Mbit full duplex)?

i got a little question, my client is an nettop ION330 from asrock, it work nicely but i have to install the nvidia driver to get gpu acceleration, we installed firefox with flash so it would be nice to have the gpu accel. Where do i install the nvidia drivers, in the chroot or in the main system ?
04:38makghosh has joined #ltsp

<dkostousov>
How I can enable root console on ltsp-client?
04:39
yoshi__: I think, it should be in the chroot. But I don't sure that acceleration works over network.
04:40
<yoshi__>
dkostousov: sudo chroot /opt/ltsp/i386 passwd u
04:41
root
04:41
sudo chroot /opt/ltsp/i386 passwd
04:41
sudo ltsp-update-image
04:43
<dkostousov>
yoshi__: I should run ltsp-update-image from the chroot?
04:43
<yoshi__>
no
04:43
from the main system
04:43
the rest is in the chroot env
04:44
if you have an 64 bit main system and 32 bit client chroot you should add the option --arch i386 to the update command
04:44
<alkisg>
Or you can put SCREEN_02=shell SCREEN_07=ldm in lts.conf, and switch to vt2 with alt+ctrl+f2 (no ltsp-update-image needed for that method)
04:44
<dkostousov>
I use x86_64 server and i586 clients. Will chroot works on it?
04:44
alkisg: thx!
04:45
<alkisg>
dkostousov: that in seperate lines, i.e.:
04:45
[Default]
04:45
SCREEN_02=shell
04:45
SCREEN_07=ldm
04:45
<dkostousov>
How I can enable full boot output on client? I have strange problem with new switch.
04:45
<alkisg>
sudo gedit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
04:45
and remove quiet splash from the end of the first line

yoshi__: to use the nvidia drivers on the clients, you need to install them on the chroot
04:46
...and also put some lts.conf options to load them
04:47
<dkostousov>
alkisg: acceleration works over network???
04:48
<alkisg>
Well first of all he's talking about localapps...
04:48
...and second, yes, some acceleration like xv does work over the network
04:48
<yoshi__>
alkisg: tx i figured it out in the mean time, now for installing the nvidea driver i have to use the mediabuntu reposistory, is it enough to put this into the main system or do i have to put that repository also in the chroot ?
04:48Selveste1___ has joined #ltsp
04:48
<alkisg>
yoshi__: what ubuntu version is that?
04:49
<yoshi__>
jaunty
04:49
<alkisg>
No medibuntu repo needed
04:49
<yoshi__>
ok tx :)
04:49
<alkisg>
How did you install the chroot? With the alternate cd?
04:50
<dkostousov>
what ltsp-update-image does?
04:50makghosh has quit IRC
04:50
<alkisg>
dkostousov: it compresses /opt/ltsp/i386 into /opt/ltsp/images/<squashfs image>
04:50
<yoshi__>
i installed the main system with alternate but not using de F4 switch, aftert the normal install i did apt-get install ltsp-server-stand...
04:50makghosh has joined #ltsp
04:51
<yoshi__>
dkostousov: you always have to do this if you install something or change something in the chroot
04:52
<dkostousov>
hmm... I thought)
04:52
<alkisg>
yoshi__: I don't remember if the restricted repository gets into the chroot with that method. Check if it's there, or copy your server's sources.list into the chroot.
04:52
<yoshi__>
because we build a new image that has to go to the clients
04:52
<dkostousov>
thought that client uses /opt/ltsp/i386 over nfs
04:52
<alkisg>
dkostousov: what distro?
04:53
<yoshi__>
alkisg: i installed with sudo ltspbuildclient
04:53
arch
04:53
i386 copysourceslist
04:53
so its there yes :)
04:53
<alkisg>
OK, I think in previous versions only the main repo was put into the chroot
04:53
<dkostousov>
I use Fedora 11
04:53
<alkisg>
dkostousov: yeah, we were talking about ubuntu and we got mixed up :)
04:54
Personally I don't know what fedora uses, it may use nfs...
04:54
<ogra>
it does ... slower but you dont need to update the image
04:56
<dkostousov>
How is it to configure network card params for a client?
04:56* alkisg wants to do a squashfs/nbd versus partition/nbd speed comparison :)
04:56
<ogra>
??
04:56
oh, partition, i read directory :P
04:57
alkisg, i doubt you seem much speed difference, but a lot more network traffic
04:57
<alkisg>
Urm, if I don't get reduced speed due to more network bandwidth, then no problem there
04:57
<ogra>
given that the unsquashing of the contents happens on read clientside ... vs transferring uncompressed data if you use a partition
04:58
<dkostousov>
Does squashfs require more memory than partition?
04:58
<ogra>
well, try it with 50-100 clients :P
04:58
dkostousov, nope, that will be about the same
04:58
<alkisg>
....well, so I'll see speed differences :)
04:58
<ogra>
the uncompressing will use a tiny bit more CPU power on the client though
04:59
<alkisg>
I don't think that's a problem usually ... even on ancient clients
04:59
<ogra>
alkisg, it might be measurable slower, but i doubt you "feel" it
04:59
<alkisg>
For fat clients it would be nice to have the chroot in a seperate partition
04:59* dkostousov wants to switch to squashfs/nbd...
05:00
<alkisg>
It would give us the ability to boot with the chroot, and graphically administer the system
05:00Selveste1__ has quit IRC
05:00
<ogra>
indeed
05:00
as i said, the speed difference wont be significant
05:00
the bandwith usage will
05:01
<alkisg>
yeah, but if the bandwidth affects the speed with e.g. 20 clients, then it's not worth it
05:01
<ogra>
i doubt it will affect speed in that amount, but in big setups you will notice

I try to use usb flash drive on ltsp client. The flash is mounted properly but all non-ascii chars looks like "?".
05:44
Where I should set encoding or codepage?
05:44
<alkisg>
Uhm that was fixed about 6-8 months ago upstream. Would it be in Fedora 11?
05:45
<ogra>
alkisg, fedora might not default to UTF-8 for the system locales
05:45Selveste1___ has quit IRC
05:45
<alkisg>
Ooooo :-O
05:45
<ogra>
which gets you in all sorts of encoding probs
05:46
not sure though

05:49garymc has quit IRC

Fedora's default locale: en_US.UTF-8
05:51

well, then it should work with the fixed ltspfs

though not sure fedora 11 has that

stable releases are based on bazaar tags

we dont roll tarballs because they have to be integrated with the distro packaging anyway ... so having plain tarballs is completely pointless
06:13
use mkdist to create a tarball for your distro, but make sure all corresponding packaging bits are in place as well

yup

a few minor updates in the VCS since then, but nothing major

fedorsa stuff even

lol
12:17

ogra: well, when people consistantly make a totally understandable typo over the years... i figured we should at least support it.

dkostousov, https://code.launchpad.net/~ltsp-upstream/ltsp/ltsp-trunk see yourself, commits that are distro specific are usually prefixed with distro name
12:17

easier than always telling people the right value ... when the right value is a typo in and of itself.
12:17
<ogra>
yeah
12:18

the day when that parameter is no longer needed will be good

pfft

you guys and your valid usecases
12:20
tsk
12:21
<dkostousov>
what is the "typo"?
12:21
<Gadi>
jammcq abbreviates "Horizontal" as "HORZ"
12:21
while many are inclined to use "HORIZ"
12:22
<vagrantc>
well, since time immemorial, the value for setting HorizSync option as HORZSYNC
12:22* Gadi thinks he was living in an 8 character world

where I can get latest ltspfs?

as a package for a distro or as code to package?

i'm getting some wierdness on a machine
12:51
it says that the target filesystem does not have /sbin/init
12:51
and drops me to a busybox shell
12:51
i have 3 other clients booting just fine, it's just this one that is having the problem
12:51
any ideas?
12:55
<dkostousov>
do you have only "default" dir in tftp?
13:00vvinet has joined #ltsp
13:00
<Gadi>
rm-rf: it most likely does not have a supported network driver in the initramfs
13:01
that would make it not be able to mount the nbd device
13:01
and therefore not be able to mount the rootfs
13:01
in the initramfs, you can test the theory by running /sbin/ifconfig
13:01
(ie in the busybox shell)

little question i installed firefox as local app with flash plugin did the NAT trick and changed my lts.conf everything works perfectly after that is installed the ubunty-restricted stuff and java in the chroot. But now when i run firefox as local app is see the plugins installed in firefox but firefox won't pick it up and use them, if i go to a java site it complains it has a missing plugin if i want to see a movie embedded it
14:21
complains again ... any idea ?
14:26
<vagrantc>
anything the plugin needs to function needs to be installed in the chroot
14:27
<yoshi__>
i installed everything in the chroot
14:27
<rm-rf>
how do i put more nic drivers in the initramfs?
14:28
<yoshi__>
did apt-get install ubuntu-restricted-extras in the chroot
14:28
and java plugin an jre in the chroot
14:28
also in the main system
14:28
and when i don't use firefox as local app that works
14:29
but as soon as i use firefox as lokal app it just works with flash but not with the rest
14:34* vagrantc looks at http://wiki.ltsp.org/twiki/bin/view/Ltsp/Ltsp5MinimumRequirements
14:35
<vagrantc>
looks like nearly everything is implemented except "5. Booting thin clients with as little as 32mb of system ram " and "7. Passing of VCI string from the client to the server (in initramfs)"
14:36
and i actually have submitted patches to initramfs-tools to implement the latter.
14:36
do the udhcp scripts pass VCI ?
14:36
configurable, that is

hi, are there any a;ternatives to setting up a LTSP client over wireless other than running thru a wireless bridge?
23:41
could I have a CD or local disk boot which sets up wifi access and then connects to the LTSP server?
23:41
<Guest36262>
sure

any url/link would help!
23:42
<johnny>
i don't have any
23:43
<dvorak_>
ok, so how do I do it?
23:43
<johnny>
you kinda need to know how to mess with bootloaders
23:43
you basically just need the same kernel and initramfs as is in the tftp directory
23:43
and a bootloader to loadthem.. like grub
23:43
or syslinux/isolinux
23:43
<dvorak_>
ok, and the root fs?
23:44
<johnny>
i'm imagining your going to mount that right?
23:44
only thing i'm not sure how to handle is setting the wifi connection parameters
23:45
<dvorak_>
so, i guess the steps are - boot the linux kernel, initrd, and a rootfs with scripts which should setup everything else?
23:46
all we really need at that point is setup wifi (initrd should have the right drivers, and X drivers I suppose) and then ssh to the ltsp server, and nfs
23:47
so, i would be surprised if someone hasn't already tried this!
