joebob777as7: We had to do this and one of my students did it.
00:00
Let me see if I can find his notes...
00:02
<joebob777as7>
that would be great!

<joebob777as7>
how long will it take? I've got to leave here soon. I don't want to rush you though.
00:04
<toddobryan_>
Have you tried running "sudo ltsp-build-client" ?
00:04
Not sure if that defaults to 32-bit on a 64-bit system...
00:04
<joebob777as7>
yes i did that and since it's a amd64 server it defaults to a an /opt/amd64 directory install
00:05
<jammcq>
joebob777as7: try this: man ltsp-build-client
00:08
<joebob777as7>
i can do a --dist to specify distrubution but it doesn't give me any options...
00:09
<jammcq>
what version of ubuntu are you using?
00:09
<joebob777as7>
feisty
00:09
<jammcq>
read the man page, look at '--arch'
00:09
<joebob777as7>
ok i see it
00:10
that looks like it but what is the paramater i use?
00:10
<jammcq>
looks to me like it says it supports "i386", "amd64" or "powerpc"
00:13
<joebob777as7>
awesome! i'll give it a try thanks a bunch!
00:22mistik1 has joined #ltsp
00:25
<joebob777as7>
jammcq: do you by chance know how the clients figure out which dist to boot from?
00:25
<jammcq>
it's in the dhcpd.conf file
00:25
that would be /etc/ltsp/dhcpd.conf
00:26
if you want to make your client boot the 386 kernel, you need to point the 'filename' entry to your 386 kernel
00:26
and you also need to change the 'root-path' in the same file
00:26
if you wanna do both 32-bit and 64-bit, there's tons of information on dhcp on the LTSP wiki
00:27
<joebob777as7>
ok thanks. do you know off hand how to do both or should i just search it up on the wiki?
00:27
<jammcq>
read the wiki
00:28
<joebob777as7>
ok will do thanks a bunch~!!!
00:28
<jammcq>
no prob
00:28
i'm heading to bed. See ya'll later

Hi everybody
07:37J45p3r has joined #ltsp
07:39
<Franckito>
Got a problem with LTSP. I installed it and use it on old dell laptops but I can't have a 102x768 resolution. I know it's possible on these laptops. When I launch an old live CD, I've got it. I don't with recent live cds.
07:39
Do you think it's an Xorg problem ? Should I use XFree ? downgrade to ltsp 4.1 ?
07:40
<cliebow>
Franckito, you can specify a modeline in an lts.conf..
07:41
X_MODE_0=800x600 or an entire modeline
07:41
<Franckito>
I don't know the screen refresh rates. I looked for infos on dell.com but couldn't find anything.
07:41
I tried that. Didn't work.
07:42
<cliebow>
this ltsp5?
07:42
<Franckito>
ltsp4.1
07:42
4.2 sorry
07:43
<cliebow>
hmmm..it should..i do that for some wonky lcd s i have in 4.2
07:44
<Franckito>
Without indicating the refresh rates ?
07:44
<cliebow>
X_MODE_0=800x600 40 800 856 976 1040 600 637 643 666
07:45
is what i have..you can pick out refresh rates with xvidtune
07:46
<Franckito>
I'll try but change 800x600 for 1024x768 ;-)
07:46
thanks for the xvidtunes tip.
07:46
<cliebow>
give it a whirl anayway 8~)
07:50
<Franckito>
Doesn't work
07:51
The card is an ATI Rage
07:52
I'll try to use xvidtunes.

I have a question, how can I install programs on client (I am using edubuntu 7.04 as ltsp server, server is amd64, but clients i386)? I set up everything, and it is working, but I want to install x11vnc on client. Have you any idea?
11:03dm_ has quit IRC
11:03dm_ has joined #ltsp
11:03
<cliebow>
needs to be installed chroot in /opt/ltsp/i386
11:03
right?
11:04
<ernierasta>
yeah, but apt-get in chroot env. can not find x11vnc
11:08muh2000_ is now known as muh2000
11:10
<ernierasta>
maybe I am doing something wrong 1. i go into chroot by: sudo chroot /opt/ltsp/i386 /bin/bash than i try to install it by: apt-get install x11vnc
11:12
maybe there is something with repositories? (i have not much experiences with debian-based distos)
11:28pscheie has quit IRC
11:37
<cliebow>
ernierasta, isnt it libvncserver?
11:38
hmmm..
11:39
in ubuntu it is x11vnc

<gdi2k_>
greetings. been experimenting with ltsp over the last few days. setup etc. all worked perfectly (thx to ubuntu integration), but I am disappointed with the terminal's performance (K6 - 533 MHz, 196 MB RAM). even at 1024 x 768 the screen draws are slow - irritatingly slow. are my expectations too high?
11:49
<cliebow>
ltsp5?
11:49
<gdi2k_>
yes
11:50
<jammcq>
gdi2k_: what video card in the client?
11:50
<cliebow>
o gra and jammcq have been doing some ..heh
11:51
<gdi2k_>
it's a trident supported card of some sort. problem is that the terminal font turns to chinese half way through the boot, so I can't actually log in to the terminal to check logs etc.
11:51
<jammcq>
hmm
11:52
<cliebow>
completely chines..or sanskrit/
11:52
<gdi2k_>
I can use a gentoo live CD to check exactly what card
11:52
<jammcq>
what version of Ubuntu ?
11:52
<gdi2k_>
well, hard to tell - Cs with little tails seem very prevalent!

11:53
(beta)
11:53
<jammcq>
hmm
11:53
i've been working alot with that lately
11:53
<cliebow>
i second the hmm..i know my ppc chroot works pretty near perfectly
11:53
<gdi2k_>
I also have an AMD 64 which I have tested as a client, works beautifully
11:53
I suspect the graphics hardware in the K6 machine is just rubbish
11:54
<jammcq>
yeah. you might also try setting: SCREEN_07 = startx
11:54
and then enable remote xdmcp in your gdm config
11:55
<gdi2k_>
I can get to the login prompt ok, but I can't switch to the first terminal and login there (as I can't see what I'm doing)
11:56
when I say login prompt, I mean the LDM login
11:57
<jammcq>
what happens if you try to login at the LDM prompt?
11:58
<gdi2k_>
I can login, works okayish. but the redraws are nastily slow
11:58
I also have an NFS issue somewhere - I see error of not being able to find the NFS server on the server when the client is booting, before it turns chinese
11:59
<ernierasta>
gdi2k: I am trying ltsp for only few hours, but i must say that performance is realy not bad (ok, it is problem to watch film, but there is only 10Mbit/s ethernet card in client)
12:01
<gdi2k_>
yeh, if I use the AMD64 machine, I can see the bandwidth hitting its limits when running youtube (at about 8MB / sec) but that's to be expected. However, on the slow machine, bandwidth never goes above 1 MB / sec outbound from the server, which sounds like the terminal is the bottleneck
12:01
(100 MBit network)
12:01
<ernierasta>
(server amd64 3000+, 1GB ram, sata disk; client P2, 300mhz, +- 200MB ram)
12:01
<jammcq>
gdi2k_: encrypting the X traffic over SSH is a huge cpu bottleneck
12:02
<gdi2k_>
ah
12:02
<jammcq>
changing to xdmcp can improve the performance alot
12:04pipedream has quit IRC
12:14
<gdi2k_>
ok, I added SCREEN_07 = startx to lts.conf and enabled remote GDM logins, but I now just get the gray X screen, no gdm
12:15
<jammcq>
you need to restart gdm for the new settings to take effect. But, it'll kill your current session, if you are logged in on the console on that server
12:15
<gdi2k_>

thx for your help Jim, using the client sans ssh works much better - it's nicely usable now

gfx quality is terrible, but that's down to the poor hardware (and being used to modern LCDs with DVI quality output)
12:47
<cliebow>
jammcq:is staratx in ubuntu much the same as 4.2's screen.d/startx?
12:47

what's the most effective way of dealing with client disconnects? it seems that there are lots of progs still running when the user logs back in - especially firefox moans about this...

what's happening?
13:45
<sbalneav>
Not much. Hey, the tickets link you sent me, didn't contain a link for the hop from Sau Paulo to Porto Alegra
13:45
You got that yet?
13:45
<jammcq>
right
13:45
that's a different airline
13:45
they were supposed to send me a confirmation via email, but it prolly got trapped in spam filters
13:45
I'll have to call them and get the details
13:46
i've got it all written down somewhere
13:46
<sbalneav>
That's fine, so long as ONE of us has it come next Tuesday :)
13:46
<jammcq>
yep
13:46
well, theoretically, we should just be able to walk up to the TAM counter and check in
13:46
it's nice to have something on paper
13:47
<sbalneav>
So, listen, I'm having a lot of trouble with this hardware I didn't get from you. Do you think you could help me debug it? :)

i've got 64bit and 32bit clients... is there a boot script i could have the server push to them first to discover or have a number to define which they boot as?
18:16
<jammcq>
joebob777as7: didn't I tell you yesterday that you can control that via the dhcpd.conf file?
18:16
it's not a script
18:16
it's a conf
18:17
<joebob777as7>
yes i know i can but i don't know how to have both types of clients i changed it to 1386 but now my 64bit client won't work...
18:17
<jammcq>
http://wiki.ltsp.org/twiki/bin/view/Ltsp/DHCP
18:17
create 2 'host' entries
18:17
one for the 32-bit client, and another for your 64-bit client
18:18
put the mac address for the 32-bit client in the 32-bit host entry
18:18
put the mac address for the 64-bit client in the 64-bit host entry
18:18
also, in the 2 host entries, you'll need 'filename' and 'root-path' entries, pointing to the proper kernel and chroot environment
18:19
<joebob777as7>
oh ok thanks a bunch.

another stupid question... i'm setting up my user's desktops... I have 6 students and I want 3 to have the same apps on the desktop and 3 to have a different set of apps on the desktops... is it best to just log in as them and set it up one by one?
18:38
<jammcq>
umm, that part I dunno. all my users get the same setup, usually Icewm
18:39
<joebob777as7>
why icewm?
18:39
<jammcq>
nice and light weight
18:40
<joebob777as7>
think i should use it instead of kubuntu? none are used to linux...
18:40
<jammcq>
hmm, dunno. my sites have lots of users, so lightweight is important
18:41
and my users have limited things they can do
18:41
<joebob777as7>
i'll only have 6 maybe 8 max... i guess i can always switch...
18:41
<jammcq>
i've got 140 users
18:41
so it's important to keep things lightweight
18:41
<joebob777as7>
wow! what is it for? what are you using for a server?
18:43

office workers in a healthcare supply company
18:43
server is a dual xeon with 4gb of ram
18:43
nothing special

i looked into the log and the newly created users even though i put that passwords never expire were coming up expired... and on my thin-client it didn't show i needed to update but when i went to log in on the server it prompted for password change... know how i can fix this so i don't have to log in to every account?
