Hi
04:19
I need help with LTSP, could someone help me?
04:21
anyone?
04:23
<elias_a>
oktioz_: Shoot.
04:24
I will try to help.
04:25
<oktioz_>
04:25
ok, so I warn you before, I am French, so sorry if my English is just bad
04:25
sorry ^^
04:26
<elias_a>
Ok. I am a Finn.
04:28
<oktioz_>
I installed LTSP Ubuntu 9.10 on my karmic koala, the DHCP server is launched, but when I launched my workstation, it got an IP, he loaded the files, and after black screen ... So there I am a little lost because it 2 days I try to run LTSP but I can not, then I reinstall ubuntu properly and I leave with a helper from 0
04:31
<elias_a>
Have you tried several clients?
04:31
Different machines?
04:32
<oktioz_>
no
04:32
I've just 1 client
04:33
by cons in another attempt the screen went to the login page but when I returned for a login and password, the server restarts, no way to connect
04:34
it told me something like: "server not responding"
04:35
04:35
and earlier I had a worry TFTP time out
04:36
<alkisg>
oktioz_: let's take the problems one by one. What is the problem _now_?
04:37
<oktioz_>
I am looking for someone to help me install my server step by step to learn
04:37mikkel has joined #ltsp
04:38
<oktioz_>
I reinstall Ubuntu 9.10 karmic koala gnome desktop, properly
04:39
I already reinstalled
04:46
<elias_a>
oktioz_: I would go totally the other way.
04:46
Use Ubuntu alternate cd to install the LTSP server.
04:47
Do not configure the system manually the first time you install a LTSP sever.
04:47
<oktioz_>
I had thought too, only in the configuration (I think) chroot bin that has bugged, so I had to take the stage
04:48
<elias_a>
https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall
04:48
^ That's the method I mean.
04:49
<oktioz_>
Yes I ve make that
04:50
but nothing
04:50pmatulis has joined #ltsp
04:51
<elias_a>
oktioz_: What happens now when you try to boot up a client?
04:52
<oktioz_>
nothing, since the facility was too much confusion, so I completely reinstalled ubuntu
04:53
<elias_a>
Did you install the LTSP system during the installation, too?
04:54
<oktioz_>
yes with F4, and I ve select "make a LTSP server"
04:55
excuse me, I misunderstood, not for this installation, I have not used the alternate cd
04:56
<elias_a>
oktioz_: Ok. No wonder, then.
04:56
Would it be possible for you to install it again using the F4 method?
04:56pths_ has quit IRC
04:57
<oktioz_>
yes it is normal that nothing happens, since nothing is installed, and justly, that's why I come to see is for you to help me do a clean install of LTSP , Will know that I do
04:58
ok no problem, I make that and I come back
04:59
When the CD is wonder that I want to use as ip 192.168.0.1 write right?
05:02
I think, elias_a I come back

this will probably be a little off topic here, but maybe someone is able to answer.
09:26
which vnc variant would I use for a linux terminal server? I need it to launch a predefined X session on client connection, and to not have any authentication (free access for everyone in the LAN).

Should I be concerned or forwarned about anything when installing ltsp-server-standalone on a ubuntu 64 bit machine?
12:52nubae has joined #ltsp
12:52nubae_ has quit IRC
12:58
<laron>
i assume not... but...
12:59
<abeehc>
dhcp
12:59
?
12:59
<laron>
i wont be using it as a dhcp server
12:59
<abeehc>
i don't think you want to install the standalone package then
12:59
<laron>
ok, what in place?
13:00
<abeehc>
just ltsp-server
13:01
<laron>
and that is everyting ltsp-server-standalone without the dhcp server?
13:01
<abeehc>
yeah
13:01
<laron>
ok
13:01
<abeehc>
it seems likely you'll need to build a 32bit chroot unless your clients are all 64 capable
13:02
i've never gone that route to this point
13:02
<alkisg>
ltsp-build-client --arch i386
13:02slidesinger has quit IRC
13:03slidesinger has joined #ltsp
13:03
<laron>
yeah, they will be 32bit clients
13:04
will i need to do ltsp-update-image --arch i386
13:04
<abeehc>
you'll wanna start with build-client as alkisg posted
13:04
i imagine
13:05
<laron>
right but if i make a change
13:05
<abeehc>
i think that's right yeah
13:05
<laron>
will i need to update the image with the --arch parameters
13:05
ok

i kinda liked it when the local apps reflected their host in the titlebar.. not seeing the same behaviour in karmic backported 5.2
14:15Lns has joined #ltsp
14:15alkisg_ has joined #ltsp
14:18
<stgraber>
abeehc: that's because you run compiz
14:18
abeehc: compiz doesn't show the host in the titlebar
14:20laron has quit IRC
14:21
<abeehc>
ahhh
14:22
ty
14:22
i think it's more accurate to say i've yet to get around to disabling compiz
14:22
<alkisg>
!compiz
14:22
<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
14:22
<abeehc>
though i've also thought maybe my users would appreciate some shiny stuff
14:22
thank you

Is anyone here using an ltsp cluster configuration? I only have about 100 ltsp clients across five servers but many of the clients are doing heavy graphic editing with GIMP or Blender and the load balancing idea sounds very good. Any problems I need to look out for?
14:48
<Lns>
puck1: you might want to go for localapps instead of loadbalancing for that
14:49
clustering will do little for heavy graphic usage (which = heavy network usage), but localapps, if your clients can handle it, will run gimp locally instead of from the server

What about GlusterFS instead of NFS any possible benefits?
14:52
I mean for Home drive storage not comunication between thin client and server
14:52
<Lns>
I wouldn't be the one to ask for that, my max client network is 35 clients =) I just have them use the same server
14:53
<puck1>
I can run that many for regular apps. OO Firefox but not GIMP just too slow.
14:56
We are a school with about 250 users that need to be able to sign on to any box. All are TC. I need the best (fastest access) solution for access to central home drives. I have an NFS server directly (GIG crossover cable) connected to all my app servers. Is there a better way???

puck1: I don't see much you can do besides maybe a RAID5 or something like that to speed up disk access...are you really writing THAT fast to users' homes?

<kusznir>
puck1: You should be fine with just an NFS server...might want to google a bit on NFS tuning and such. Also, as Lns said, might want to go with RAID5 (preferably hardware raid, such as the 3ware cards), espicially if this is user data that you don't want to loose (RAID5 will allow you to tolerate one disk failure without data loss while also improving disk I/O performance)
16:12
<Lns>
...and if it really comes down to it you could do some sort of redundant/dual/cluster nfs server thingie, which i've never done or even thought of before
16:12
<kusznir>
puck1: just read higher up the screen..If your issue is with graphic loads, then the user homedirectory won't effect things much..your bottlenecks are network, and (at least with some graphical apps), the way they do their X stuff.
16:13
We have an issue where when users run Inkscape, it takes minutes to load the main window. Its not disk I/O bound anywhere, nor is it CPU bound. And, as best as we can tell, its not net bound (at least, we've given it a free and clear Gig-E connection, and it doesn't make a difference). That would be something to run local if possible, or consider using NX.

Hello all. I just found out that Intel Dual Atom Motherbaord wit built in CPU.. the famous internet centric cheap solution from intle with RealTek 8111C doesnt come with PXE support.. is there any product similar i can buy that does?
21:16
this is the erfect motherbaord + cpu.. its so sad it doesnt have PXE (no i dont want to do gpxe)
21:18
(that was a 1gbit NIC)
21:19
Mobo is D945GCLF2
22:05
<johnny>
you would have to use a floppy/cd/usb key
22:05
or buy a rom for it..
22:05
<epaphus>
johnny, where do i buy a rom for it?
22:05
<johnny>
i have no idea
22:05
<epaphus>
how easy is that?
22:05
<johnny>
maybe they don't cell phone
22:06
err sell one
22:06
no idea
22:06
better to just use a usb/floppy/cd
22:06
or buy a new network card
22:06
definitely cheaper
22:06
<epaphus>
i can buy a new network card. Where?
22:06
which one
22:06
:)
22:06
<johnny>
i don't know
22:06
pick one
22:06
that comes with pxe
22:06
<epaphus>
in newegg.com only 3 have PXE
22:06
thats hilarious
22:07
<johnny>
just use a usb key..
22:07
much cheaper
22:08
<epaphus>
i could use a sd card.. thats more feasable
22:08
a 2GB one
22:08
<johnny>
if your mobo has sd card booting support..
22:08
probably doesn't..
22:08
<epaphus>
damn
22:08
i thought it saw it as a regular USB
22:08
<johnny>
you won't know until you try
22:08
who knows
22:08
i have no experience
