hello guys... can anyone help me with user config for ltsp 5 on ubuntu 10.10 desktop?
07:46
anyone?
07:47
<Appiah>
what user config?
07:50
<rudie>
i want to limit user disk space
07:51
the main issue is this : i have a thin client with embedded linux it connects to the ltsp on ubuntu but i have the cli prompt... can i enable gui by default?
07:51
it uses ssh
07:51
to connect
07:53vmu has joined #ltsp

<rudie>
anyone?
07:54
come on... there might be some help around here! :(
07:58
<muppis>
It is called quota and used in fs level.. Works.
08:04BWMerlin has quit IRC
08:05
<Appiah>
just configure the quota then rudie
08:05
there no special ltsp quota , just regular linux server stuff!
08:06
about the thin client , you dont want to PXE boot it?
08:06
<rudie>
no i dont want to pxe boot
08:06
it has embedded linux in its flash memory
08:07
<Appiah>
well if you can get the LDM onto the thin client ....
08:07
<rudie>
when i connect to ltsp over ssh i get cli i want gui
08:07
<Appiah>
(never done it before but would sure like to try someday)
08:07
<rudie>
i cannot run any files on thin client
08:07
else there are many options like FreeNX
08:07buffalosolja has quit IRC
08:08
<rudie>
is it possible to get the gui over ssh?
08:08
<Appiah>
I bet it does not have LTSP as a option :)
08:08
LTSP uses LDM as its graphical login and handling alot of other ltsp stuff
08:08
so if you can get that onto the thin client then yes
08:09
<rudie>
i have many connection types like rdp, ssh, web, etc
08:09
taratulla
08:09
<Appiah>
yes I understand
08:10
<rudie>
only this is the medium to connect
08:10
<Appiah>
non of them are for LTSP ofcourse
08:10
<rudie>
how can i get a graphical user interface then ?
08:10
:(
08:11
<Appiah>
chances are 99.99% that your thin clients embeeded OS dont have a "Connect to LTSP" option
08:12
<rudie>
nope it doesnt
08:13
<Appiah>
Dunno if such exist O_o
08:14
1) PXEboot 2) Reflash the memory 3) edit the embeeded OS
08:14
that's some options I can think of
08:14
<rudie>
PXEboot works fine but its quiet slow
08:14
reflash? how can i?
08:14
<Appiah>
errr
08:15
sorry I meant "Install another OS"
08:15
<rudie>
me = noob :((
08:15
yeah but how do i do it?
08:15
on a flash memory?
08:15
its called dom i guess
08:15
<Appiah>
same way you install it on harddrive or usb stick
08:16
but your space is really limited
08:16
<rudie>
but which os supprts ltsp?
08:16
<Appiah>
in that way
08:16
<rudie>
i mean client os for ltsp?
08:16
<Appiah>
I have no idea
08:16
<rudie>
yeah i have 1 gb space
08:16
<Appiah>
Dont know if such exist
08:16
<rudie>
:(
08:16
<Appiah>
I would like to have it
08:16
something you could put on a thin clients memory, no pxebooting
08:16
just starts and fires up LDM
08:17
<alkisg>
If you want to use freenx, just install freenx on the server...
08:18
<rudie>
i can use freenx
08:18
but how do i install it on server?
08:18
i cannot run files on this dumb linux
08:18
i dont have a terminal either
08:18
<alkisg>
You mean on the client or on the server?
08:18
<rudie>
this client
08:19
i cannot run files on this linux client dont have terminal too
08:19
<alkisg>
What options does it have? For rdp, you can install an rdp server
08:19
<rudie>
all i have is firefox n open office
08:19mistik1_ has joined #ltsp
08:19
<rudie>
on linux server?
08:19
<alkisg>
Yes
08:19mistik1 has quit IRC
08:19mistik1_ is now known as mistik1
08:19
<alkisg>
But *all* this is not ltsp related, so you're probably in the wrong channel...
08:22
<rudie>
which channel shall i join to install rdp server on ubuntu desktop edition?
08:24
<alkisg>
Maybe #ubuntu? Not sure
08:24
<rudie>
no one?
08:24
k...
08:24
thanx
08:24
<alkisg>
np
08:24
<rudie>
thanks Appiah for listening to me
08:24
:)
08:27
<Appiah>
I dont remeber if it was here on the irc or the mailing list when someone was telling about the progress on a similar solution
08:27
instead of PXEbooting , putting that image on thin client
08:28
<alkisg>
I want to implement this some time (and it's been implemented in the past by some university), but there's no support for it in the current upstream code...
08:29
But I think rudie isn't looking to put LTSP in his image, otherwise he could just netboot...
08:29
(I'm interested in locally booted LTSP fat clients over wireless, which can't be netbooted easily)

alkisg: Hi !!
08:32
<alkisg>
Hello
08:33
<Trixboxer>
Things are good till now :)
08:33
one small doubt
08:33rudie has left #ltsp
08:33
<Trixboxer>
in top -c on fat client I see a process sshfs
08:34
does it mean that the nbd is using SSHFS for mounting remote sys ?
08:35
<alkisg>
No, the root file system (/) is mounted with NBD and the /home/username folder is mounted with SSHFS.
08:37
<cyberorg>
alkisg, ltsp image that can be installed on client DOM can be easily created using kiwi
08:37
<Appiah>
ofcourse, the powerful suse has already solved this problem :)
08:37
<alkisg>
cyberorg: nice, what does DOM mean?
08:38
<Appiah>
memory on the thin client is called DOM
08:38
<cyberorg>
alkisg, some TC comes with their own flash storage called DOM
08:38
<Appiah>
Disk On Module
08:38
<alkisg>
Ah, I see. Can that be a local hard disk?
08:38
(for a normal desktop used as a fat client...)
08:38
<Appiah>
but that would really solve the thinclients/fatclients with wireless
08:39
wireless only*
08:40vmlintu has quit IRC
08:40
<cyberorg>
alkisg, of course, local hd image that can be dd'ed or pxeboot installed can be done too
08:40
<alkisg>
Nice!
08:41
<Appiah>
this kiwi features needs to go upstream..
08:41
<alkisg>
cyberorg: is that possible? ^^^ or is it kiwi-depended?
08:42
<cyberorg>
Appiah, kiwi needs to be ported to other distros, currently it supports suse and rh based
08:42
<Appiah>
what's the kiwi in kiwi-ltsp anyways?
08:43
<cyberorg>
kiwi is imaging solution, you know what ltsp is :)
08:43
<Appiah>
ah :)
08:43* alkisg would like to implement this: the clients to boot locally, but before they reach LDM, to check if opt/ltsp/i386 on the server is newer, and if it is, rsync it over wireless... that would make it rather easy to maintain labs with several netbooks
08:44
<Appiah>
!!
08:44
<ltspbot>
Appiah: Error: "!" is not a valid command.
08:44
<Appiah>
that would be just great

ltspbot: shutup!
08:44
<ltspbot>
Appiah: Error: "shutup!" is not a valid command.
08:44
<cyberorg>
Appiah, kiwi does that too, update on boot
08:44
<Appiah>
=(
08:44
<Trixboxer>
haha
08:44
<alkisg>
Ooooh nice!
08:44
<Appiah>
Guess kiwi needs to get ported
08:44
fast
08:45
<Trixboxer>
!ltspbot
08:45
<ltspbot>
Trixboxer: Error: "ltspbot" is not a valid command.
08:45
<Trixboxer>
hmm
08:46
alkisg: So is there anything remaining to improve the nbd performance in order to give a local HDD feel ?
08:46
<cyberorg>
check out kiwi doc http://isny.homelinux.com/data/kiwi.html all the features it provides is why we use it for LTSP on opensuse
08:46
<Trixboxer>
like disabling encryption 0_o
08:46
<alkisg>
Trixboxer: disable nbd-proxy, re-enable compression in /etc/ltsp/ltsp-update-image.conf, upgrade your network to gigabit..
08:47
<Appiah>
cyberorg: about porting , does kiwi not use rpm , yast and or smart? would that not make it hard to port to (example) debian ?
08:47
<cyberorg>
porting shouldn't be difficult, it supports smart too
08:48
smart, yum and zypper are supported, so someone can write support to whatever deb uses easily
08:49
<Appiah>
I can just start googling and reading the kiwi mailinglist but do you know of any porting efforts?
08:52
<cyberorg>
Appiah, nopes, you can always drop in #kiwi and get help from schaefi, check out the code and parts which handle package manager
08:53
got to go, ciao
08:53
<Appiah>
thanks

i've set TIMESERVER=192.168.2.1 variable in lts.conf ... i've rebooted my client, but it's not picking up the time from the server. it's like 6 hours and 30 minutes off. what else should i be doing to fix this? is there a way i can test it? i can ping the time server. i just ran ntpdate 192.168.2.1 and that worked. when is the client supposed to check the time server, at startup?
09:26
<Appiah>
https://help.ubuntu.com/community/UbuntuLTSP/InstallNTPServer looks like there's more O_o
09:26
dunno if it's changed after 8.0.4
09:26
8.04*
09:27
<AndyGraybeal>
well, that's old, and i talked to, i think it was alkisg this weekend and he said all i need to do is set TIMESERVER
09:27
i told him i would update that page if i got this to woek
09:27
work
09:27
<Appiah>
never seen/heard of anyone using TIMESERVER
09:27
(this is new to me) :)
09:28
but there is ntpdate in the chroot?
09:28
<AndyGraybeal>
it still looks like i need to run the script. i think alkisg said i didn't have to run the script though.
09:28
Appiah: yes, there is.
09:28
Appiah: that works fine.
09:29
<Trixboxer>
can somebody from dev please update the man page of "ltsp-build-client" command to include "--fat-client" ?
09:30
if I can, I would love to but I'm not a dev*...
09:30
<AndyGraybeal>
Trixboxer: you run trixbox (Asterisk?)
09:30
<Trixboxer>
yup :)
09:30
<AndyGraybeal>
cool :)
09:31
<Trixboxer>
I don't find "--fat-client" option in "man ltsp-build-client", thought is executes pretty good :)
09:31
Using Ubuntu 10.04 as server
09:32
<Appiah>
hidden feature!
09:33
<Trixboxer>
Appiah: It was hidden for me till alkisg revealed it

mhm...
09:49
Recently I made a Dutch translation of LDM, for the company I work for
09:50
Someone here suggested I e-mail it to ltsp-developer@lists.sourceforge.net, which I did
09:50
Since then it's been dead quiet. Did I do it right? =)

Okay, as long as it has arrived. Hopefully it'll be used. Quite happy with LTSP at the moment, very nice to be able to do something back.

Too bad the accountant here is using some program that's not compatible with Linux. Would've saved me from having to set up an RDP server here. :-)

After installing a new software in host system, how can I make it accessible in fat-clients ? e.g Thunderbird or Chrome ?
11:20
<alkisg>
!fatclients
11:20
<ltspbot>
alkisg: "fatclients" :: You may find some info about the Ubuntu/LTSP implementation of fat clients at https://help.ubuntu.com/community/UbuntuLTSP/FatClients
11:20
<alkisg>
See the section about chroot customizations
11:21
<Trixboxer>
are u suggesting that I should chroot to client environment first and then install the app ?
11:21
trying ...
11:28
<alkisg>
Right, on fat clients the apps need to be installed on the chroot, not on the server.
11:29
<Trixboxer>
alkisg: Did it but no effect on client even after rebooting, I installed chrome in chroot environment
11:29
<alkisg>
Trixboxer: did you run ltsp-update-image?
11:29
<Trixboxer>
nope, initiated now
11:29
<alkisg>
Trixboxer: about the man page, see ltsp-build-client --extra-help
11:30
<AndyGraybeal>
so for some reason i don't have /opt/ltsp ....
11:31
i'm very scared.
11:32
<alkisg>
AndyGraybeal: erm, did you say you're having login problems? How did your client boot without /opt/ltsp/images/i386.img?!
11:33
About the TIMESERVER problem, you don't have to add any scripts, it should work out of the box - if it doesn't it needs troubleshooting, but with /opt/ltsp missing that would be difficult... :(
11:33
<AndyGraybeal>
alkisg: yea, this is a totally different issue.. i don't know what the f i did.... i didn't delete anything
11:34jroberts235 has joined #ltsp
11:34
<alkisg>
AndyGraybeal: if a client is booted, `ps -ef|grep nbd` will tell you the image it uses
11:34
<AndyGraybeal>
alkisg: no one can login... the thing boots thouhg.. i'm so confused.
11:34
okay thank you
11:34
oh wait.. i was stil in chroot
11:34
<alkisg>
AndyGraybeal: about the login problem, if you changed your server's IP, then ltsp-update-sshkeys && ltsp-update-image is needed
11:34
Heh :)
11:35
<AndyGraybeal>
gah that's not the first time i've done that
11:35
alkisg: i haven't changed the IP address.. but i did 'start' the ssh daemon
11:35
i tried to install 'openssh-server' but i think it said it was already up dated
11:36
i'm sorry for this panic
11:36
<alkisg>
You can run those commands if you like, or you can troubleshoot by using SCREEN_02=shell in lts.conf and trying "ssh user@server" from there
11:36
<AndyGraybeal>
ssh_user@server (server = ip address of ltsp server?)
11:36
thank you
11:36
<alkisg>
AndyGraybeal: the exact word "server"
11:36
<AndyGraybeal>
lemme run update-sshkeys first
11:37
<alkisg>
ssh <user>@server
11:37
You only replace <user> in that line
11:37
<AndyGraybeal>
aah interesting, okay.

alkisg: Error: "sshkeys" is not a valid command.
11:38
<alkisg>
!learn sshkeys as If you changed your LTSP server IP on Ubuntu, your clients will be unable to login. To fix this, you need to run: sudo ltsp-update-sshkeys && sudo ltsp-update-image
11:38
<ltspbot>
alkisg: The operation succeeded.

hi, where do i faind some docs about setting up sound in ltsp?
11:38
find*
11:38
<alkisg>
distro/version?
11:39
<Kicer86>
debian squeeze'
11:40
currently i've pulseaudio is running on server and client but no sound in speakers...
11:40
<alkisg>
No idea about sound on Debian, if noone answers try in a few hours when usually the debian maintainer signs in
11:42
<Kicer86>
kk
11:42
<AndyGraybeal>
alkisg: your a life saver! holy crap sshkeys update worked.

Trixboxer: so you run sudo chroot /opt/ltsp/i386 apt-get install app && sudo ltsp-update-image and then rebooted the client and you don't see the app?
11:49
<Trixboxer>
yes
11:49
strange thing is
11:50
even after installing chrome in chroot env
11:50
it dint go in /usr/bin/

i'm supposed to install alsa plugin for pulseaudio on server or thinclient environment ?:>
13:29
<vagrantc>
if you should install it in the chroot, it will explicitly tell you to do so
13:35vmlintu has quit IRC
13:38
<vagrantc>
Kicer86: technically, i think you need libasound2-plugins on both the server and the chroot, but by default it should already be in the chroot.
13:38
<Kicer86>
indeed they are
13:39
<vagrantc>
so the /etc/asound.conf is only needed on the server.
13:42
<Kicer86>

my chroot is in some other place than /opt

13:56
probably not the cause of your problem, but makes it harder to troubleshoot

my chroot ?
13:56
<vagrantc>
yes ... using the non-default location
13:57

what's the different ?:P

well, you've already pointed out one difference ...

BASE=/whereever/you/put/your/chroot ltsp-info
13:58
and please pastebot the results
13:59
it's not that there's anything technically wrong with putting it elsewhere ... it's just that most of the tools assume /opt/ltsp so you'll have to explicitly state the location for many/most of the tools.

looks like you're running a lenny chroot on a squeeze server ...
14:02
is that intentional?
14:02
the lenny version doesn't set the same variables that the squeeze documentation looks for
14:03
but i'd really recommend building a squeeze chroot ...
14:03
or at the very least, using lenny-backports for the chroot.
14:04
<Kicer86>
then wait a sec
14:04
<vagrantc>
putting anything in the /mnt directory is a bit strange... that's usually used for temporary ad-hoc mounts ...
14:05vmlintu has joined #ltsp

<Kicer86>
is there any difference if i use aptitude update when chrooted ? or should i use ltsp-build-.... ?
14:06
<vagrantc>
i would start from scratch
14:06
<Kicer86>
kk
14:06
<vagrantc>
and, if you could bear to do so, put it in /opt/ltsp :)
14:06
you can always move it later, if you must
14:06
<Kicer86>
kk
14:09
<vagrantc>
so, be sure to use ltsp-build-client --dist squeeze ... just in case your lsb_release lies and says you're running lenny
14:09
<AndyGraybeal>
does anyone use apcupsd on clients?
14:09
<vagrantc>
UPS ought to last a long time on a genuine thin client
14:10
though you'd still need the server to outlast it ... :)
14:10
<AndyGraybeal>
vagrantc: well, it's more for monitoring the UPS with NRPE/nagios
14:11
<vagrantc>
AndyGraybeal: why would you want that on the thin client?
14:11
<AndyGraybeal>
so i can know when to replace the battery or something like that
14:11
<vagrantc>
why not have the server monitor the UPS?
14:12
<AndyGraybeal>
i'm confused on how to do that i suppose.
14:12
<vagrantc>
i guess i just don't understand what you're trying to do
14:12
<AndyGraybeal>
i hvae UPS on my server, and UPS on each of the clients. i have apcupsd on the server.. and i monitor it with nagios. i would like to do the same for the clients.
14:13
<vagrantc>
connected to the UPS with serial cables?
14:13
<AndyGraybeal>
well, with usb to the client, yes.
14:14
<vagrantc>
UPSes aren't network-capable, i'm guessing
14:14
<Trixboxer>
alkisg: nope
14:14
<AndyGraybeal>
vagrantc: not that i'm aware of
14:14
<Trixboxer>
alkisg: I don know why but its not showing chrome in clinet
14:14
client*
14:14
<AndyGraybeal>
i have APC ups's.. maybe their not such high quality.
14:15
vagrantc: i'm going to try it out, it sounds like it hasn' tbeen done yet. can you forsee any problem with me running apcupsd on the clients?
14:15
<vagrantc>
AndyGraybeal: well, if acquiring network cards for your UPSes is an option, that would definitely simplify things ... but if that isn't an option...
14:16
<AndyGraybeal>
i don't think there is such an option, lemme google.
14:16
<vagrantc>
AndyGraybeal: the main problem i see running it on the clients is getting each client to recognize the appropriate UPS
14:16
<AndyGraybeal>
http://www.apc.com/products/family/index.cfm?id=98
14:16
<alkisg>
Trixboxer: is that chromium-browser, or google chrome? If the latter, how did you install it to the chroot?
14:16
<AndyGraybeal>
i thought all i would have to do is edit apcupsd.conf and tell it 'usb' :)
14:17
<vagrantc>
we played around with using USB serial adapters for a while, and finally switched to networked setup... much simpler.
14:17
<Trixboxer>
alkisg: chromium-browser
14:17
<vagrantc>
AndyGraybeal: nothing like giving it a whirl :)
14:17
<alkisg>
Trixboxer: ok, on a fat client, try: dpkg -l chromium-browser
14:17
<AndyGraybeal>
vagrantc: i've didn't realize there was 'network management cards' for UPS's
14:18
<Trixboxer>
alkisg: no package found
14:19
<alkisg>
Trixboxer: right, so it isn't installed (or you didn't run ltsp-update-image or didn't reboot the client)
14:19
<Trixboxer>
done
14:19
it wrote another image
14:19
and now rebooted
14:20
<alkisg>
Trixboxer: sudo chroot /opt/ltsp/i386 dpkg -l chromium-browser
14:21
<vagrantc>
AndyGraybeal: they're great :)
14:22
<Trixboxer>
alkisg: its installed
14:22
<alkisg>
Trixboxer: sudo mount -o loop /opt/ltsp/images/i386.img /mnt && sudo chroot /mnt dpkg -l chromium-browser && sudo umount /mnt
14:24
<Trixboxer>
not able to mount
14:24
<alkisg>
Is that the correct path for your image?
14:24
<Trixboxer>
it says "need an entry in fstab"
14:24
lemme check
14:24
I have 2 images there i386.img and fat-i386.img
14:25
<alkisg>
Ah. Why?
14:25
Also in that case, every time you run ltsp-update-image etc you need to tell it about that new path you're using.
14:25
<Trixboxer>
example ?
14:26
<alkisg>
ltsp-update-image --arch fat-i386
14:26
<Trixboxer>
oh
14:26
<alkisg>
It'd be much simpler if you just had 1 chroot
14:26
So if you don't have some specific reason to have 2, just keep one of them
14:27
<Trixboxer>
is it safe to delete both and create a new one ?
14:27
<alkisg>
Sure, but it'd take a lot of time and you don't need to do it
14:27
Try this:
14:27
du -sh /opt/ltsp/i386
14:27
du -sh /opt/ltsp/fat-i386
14:27
Ah, better yet:
14:28
ls /opt/ltsp/*/etc/ltsp_fatchroot
14:28
This will verify that fat-i386 is the fat one, the one you want to keep
14:28
<Trixboxer>
ok give me a min
14:28
its updating the image
14:29
<alkisg>
ls /opt/ltsp/*/etc/ltsp_fat_chroot
14:29
^^ that's the correct one
14:29vmlintu has quit IRC
14:29
<alkisg>
So if fat-i386 is the correct one, delete the i386 one and rename fat-i386 to plain i386
14:30
<Trixboxer>
I did it before
14:30
like 4 hours before
14:31
ok
14:31
<alkisg>
Trixboxer: if you did it before, then maybe your dhcp server is pointing to the old image
14:31
<Trixboxer>
now my /opt/ltsp has i386 and images
14:31

Trixboxer: ls -lha /opt/ltsp/images

(or the old one depending on what you did)
14:32
<Trixboxer>
hmm
14:32

14:34
/etc/ltsp/dhcpd.conf is Ok
14:34

Delete the fat-i386 line from inetd.conf and restart inetd
14:35
Also check the port in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
14:35

14:35
<alkisg>
(and delete /var/lib/tftpboot/ltsp/fat-i386/

Trixboxer: ok, put the following info to pastebin:
15:02
grep nbd /etc/inetd.conf
15:02
ls -lha /opt/ltsp/images
15:02
cat /etc/ltsp/dhcpd.conf

cat /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default
15:03alexqwesa has joined #ltsp
15:03
<alkisg>
Btw, the next time you run ltsp-update-image, run it with the --force parameter so that it re-assigns the nbd ports now that you only have 1 image
15:04
(and since you were looking for speed, you could also disable nbd-proxy and re-enable compression for 3x disk speed)
15:05
<Trixboxer>
yeah its the nbd port conflict again and here is the pastebin http://pastebin.com/LekY7nGH
15:05
alkisg: disable nbd-proxy from lts.conf ?
15:05
<alkisg>
Is that lucid?
15:05
<Trixboxer>
yes
15:06
can I add it to kernel ?
15:06
BOOTPROMPT_OPTIONS="quiet splash nbd_proxy=false"
15:06
<alkisg>
You'd need to get a newer version for one script, comment #13 in https://bugs.launchpad.net/ltsp/+bug/589034
15:06
So nbd_proxy=false is needed but it isn't enough
15:07
(for Lucid, it is enough only for maverick which has the newer script version)
15:07
Or if you prefer you can add my ppa in your sources and update your chroot...
15:09
(the "connect to nbd failed" problem of course is because of the port, temporarily change it manually to 2000 and next time put --force to ltsp-update-image)
15:09
<Trixboxer>
trying the force option and then will disable the nbd_proxy
15:13vmlintu has quit IRC

last problem: using X_MODE_0=1024x768 doesn't work. thin client starts with 800x600. with debian lenny's ltsp it was ok
15:16
XRANDR_MODE_0 has no effect too
15:16
<Trixboxer>
alkisg: why nbd_proxy is introduced ? I read that you are also a part of it
15:17
<alkisg>
No, I'm not, I don't even use it
15:17
Where did you read that?
15:17
(that's why I put the nbd_proxy=false parameter, because nbd-proxy has caused some problems in my systems and I didn't want to use it..)
15:18
<Trixboxer>
no no, I read that u are working on its removal ? on the same #ltsp channel but lost in logs
15:18
ok, now i downloaded the new ltsp_nbd
15:18
<alkisg>
Nope, I'm not working on its removal either :)
15:18
Some people need it, I was just looking for an option to disable it on my labs
15:19
<Trixboxer>
huh, I think I need a tea then :@
15:19
<vagrantc>
Kicer86: probably an issue with the switch to kernel-mode-setting ... depends on your video card ... look for bugs in the appropriate xserver-xorg-video-* packages.
15:19
<Trixboxer>
i downloaded the new ltsp_nbd, chroot , update-initramfs -u , and then on main server ltsp-update-kernels
15:19
<alkisg>
Trixboxer: I do think that forking nbd-client would result in a more efficient implementation, but it's not my call, I was only looking for a method to disable it....
15:20
<Trixboxer>
alkisg: rebooting the server now
15:20
<alkisg>
Trixboxer: you won't get much performance improvement with that
15:20
<Trixboxer>
with nbd_proxy disable ?
15:20
<alkisg>
You'd need to also disable compression in ltsp-update-image.conf like I told you some hours ago
15:21
<Trixboxer>
oops, I missed it, ok will disable after this reboot
15:21
<alkisg>
(the compression gives the most speed-up, but I heard that nbd-proxy has problems with compressed images, and that's why compression was disabled in Lucid, so that's why I told you to disable nbd-proxy while enabling the compression)
15:21
<Trixboxer>
recalling days of windows when I need to reboot after every driver installation :P
15:21
<alkisg>
No need to reboot the server after updating your image...
15:22
<Kicer86>
vagrantc: ok, thx
15:24
<alkisg>
Trixboxer: your current /opt/ltsp/images/i386.img is 1.7 Gb, after enabling the compression and running ltsp-update-image it will get 2-3 times smaller, giving you 2-3 times better disk speed.
15:24
<Trixboxer>
alkisg: yes the image size now is 1.7 gb
15:24
and I see that client booted safely
15:25
now checking out how to enable the compression

15:28

I didn't observe that in more than 1000 clients
15:29
I suspect that the instability may be caused by nbd-proxy, but I can't say for sure until I see instability :)

Hi markit

alkisg: do you know if kubuntu 10.10 still needs ndb-proxy patch? I've "upgraded" the school server to 10.10, but now is at my home and can't test with many clients
17:43
<alkisg>
nbd-proxy should be enabled by default in 10.10. If you want to disable it, follow the instructions on the bug report
17:44
<markit>
alkisg: I thought that the problems was not it being enabled, but a "fix" broke it, so hoped they fixed the fix
17:44
<alkisg>
markit: ?
17:44
<markit>
in recent ltsp there is the statement "that now nbd-prxy can be disabled" , but did not found how to do it
17:45
<alkisg>
nbd-proxy is enabled by default in ubuntu 10.04 and 10.10
17:45
<markit>
alkisg: I thought that nbd-proxy was there since long time, and worked fine, until some developer "improved" it an broke it... are you telling me it never worked?
17:45
alkisg: yes, I know is enabled by default, but if you read the changelog of 10.10 ltsp, states that now is possible to disable
17:45
<alkisg>
No, I'm telling you that it was only recently added, and only a few people (me included) had to disable it
17:46
<markit>
so seems like they added a config option
17:46
ah, me included :)
17:46

I know that it is possible to disable it, I added the disabling code because it had problems in my setups and I didn't want to use it...

alkisg: ok, so I just have to add "thanks you fro having added that patch" :)
17:51
<alkisg>
Erm, I added the code before the bug report was even filed... :D
17:51
...so I didn't use the patch from the bug report...
17:53
<markit>
btw, are you still improving your script sch-scripts and updating .debs also?
17:53
I definetly have to try to install it this or the next week
17:54
<alkisg>
Yes, but I'm not producing any newer i18n versions because it seems like only dgroos is using it :)
17:55
We've added support for sending messages, for getting a user or a root client console in the teacher pc etc, lots of new stuff
17:56
I think the last i18n version is 10.04.38, now we're at 10.04.51.
17:56
<markit>
i18n version? I thought was not i18n and just dgross translated "by hand" in english
17:57* markit confused
17:57
<alkisg>
In order for you or any other interested people to try it, I uploaded i18n .deb files and I sent you the link for it...
17:57
(I mean, in english, not multilingual...)
17:58
<markit>
ah, I see
18:00
any regression in 10.10 and ltsp that cames with it that I should be aware of?
18:01
<alkisg>
No idea, I'm sticking to 10.04 until the next LTS comes out :)
18:02
<markit>
good idea, but unfortunatly recent kde is not backported to 10.04, and I also needed more recent scribus-ng
18:02
also I think I'm a bit masochist... so I upgraded :)

<vagrantc>
can separate your application server from your LTSP server.
18:03
<markit>
vagrantc: is it a question?
18:04
<vagrantc>
markit: no, a statement :)
18:05
(you) can ...
18:05
<markit>
mmm interesting but sounds too complicated at the moment
18:05
expecially if maverik works fine, I do hope
18:06
<vagrantc>
hope is useful to have
