hi all. am in a bit of a pickle. remotely upgraded ltsp server from debian lenny to squeeze and ltsp is broken. looks like an issue with tftpd-hpa - clients report file not found. anybody know offhand of anything that changed?
04:09
i can see tftpd is no longer being started by inetd and has its own config file
04:09
grr - couldn't see this in docs
04:11
and it's listening on /srv/tftp not /var/lib/tftpboot
04:11
anyone know if this is documented anywhere? otherwise i think users could get a surprise when squeeze is released

hi. Is there something else besides MIC_VOLUME to control the default mic volume level at the client ?
09:32alkisg has joined #ltsp
09:48
<alkisg>
dekelev: run `amixer -c0 scontents` *locally* in your client to see a list of controls (which in turn can be configured from lts.conf)
09:51
(e.g. you may need "MIC_BOOST_SWITCH=on")
09:51
<dekelev>
hi alkisg
09:51
<alkisg>
Hi
09:52
<dekelev>
I'm asking this because when I set MIC_VOLUME=0 for example, I reboot client and mic volume stays the same
09:53
<alkisg>
distro/version?
09:53
ballongen: recent ubuntu versions contain ltsp 5
09:54
<dekelev>
ubuntu 10.04
09:54
<alkisg>
!localxterm
09:54
<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.
09:55
<alkisg>
dekelev: on a localxterm (see above), run: getltscfg -a
09:55
...and paste the contents to pastebin
09:55
<dekelev>
ok
09:58bobby_C has joined #ltsp
10:02
<dekelev>
ok, so I couldn't copy xterm content, but I saw there MIC_VOLUME="30" & FRONT_MIC_VOLUME="30"
10:04
<alkisg>
(in X windows, middle mouse click copies just by selecting stuff, no need to copy/paste)
10:04
<dekelev>
but If I click on speaker icon in gnome panel and go to 'Sound Preferences', I see mic volume around 85%
10:04
<alkisg>
OK, and what about: amixer -c0 scontents
10:04
(again, locally)
10:04
<dekelev>
I'll try them both and paste to pastebin
10:09bobby_C has quit IRC
10:10
<dekelev>
how do I paste to pastebin?
10:10
<alkisg>
!pastebot
10:10
<ltspbot`>
alkisg: "pastebot" :: The LTSP pastebot is at http://ltsp.pastebin.com. Please paste all text longer than a line or two to the pastebot, as it helps to reduce traffic in the channel. Don't forget to paste the URL of the text here.
10:11
<dekelev>
I pasted getltscfg -a output
10:11
but on amixer command I got 'Invalid card number'
10:11
<alkisg>
So that's the problem then
10:12
Which sound card is that? Can you see it with lspci ?
10:13
btw, does this run ok? amixer scontents
10:15
<dekelev>
I'v paste lspci output
10:16
<alkisg>
Seems ok, does `amixer scontents` (without -c0) run ok?
10:16
Or does it say "invalid card number" too?
10:17
<dekelev>
amixer: Mixer attach default error: No such file or directory
10:17
this is the error from amixer scontents
10:17
I had this issue with all my test clients
10:17
<alkisg>
That doesn't look good. Did you mess with the setup, while trying to set up twinkle or something?
10:19
Anyway, so the problem is that amixer isn't working, but I don't know how you can fix it, it's beyond my sound skills. Try to find Gadi for that :)
10:20
<dekelev>
might be, but It's a test server anyway so maybe it best if I leave it and just hope that with production server it won't happen
10:21
thanks for the time!
10:21
:)
10:21

<ballongen>
alkis: oh, nice. thanks
10:23
do i need a tftpd server for ubuntu ltsp-complete package?
10:24
<alkisg>
No, ltsp-server depends on tftpd-hpa, so it'll be automatically installed
10:24
The easiest way is to installed with the alternate cd, and press "F4 => install an ltsp server"
10:24
<ballongen>
i thought so, thanks
10:24
yeah, but i want it on my ubuntu-desktop
10:25
<alkisg>
OK, then "sudo apt-get install ltsp-server-standalone" and "sudo ltsp-build-client"
10:26
<ballongen>
yeah did that. i think my problems is in my router. i get TFTP...... and then PXE-E11 ARP Timeout TFTP cannot open connection
10:26
<alkisg>
Do you have a dhcp server in your router?
10:27
and, 2 nics on the ltsp server or just 1?
10:27
<ballongen>
i'm not using the most ideal method. :) I have a linksys router with DD-WRT. singel nic on ubuntu. using dhcp-option=13,25
10:27
dhcp-option=66,172.20.20.200
10:27
dhcp-boot=pxelinux.0,172.20.20.200 on the router
10:28
i know i need to read the manual more. :)
10:29
<alkisg>
I'm not familiar with that syntax, but the default boot filename is /ltsp/i386/pxelinux.0, not just pxelinu.x0
10:30
<ballongen>
i will try it
10:30
<alkisg>
(btw in that case you didn't need to install ltsp-server-standalone, but ltsp-server, as you don't need a dhcp server in the ltsp server)
10:30
<ballongen>
ohh
10:30
well, already done
10:30
<alkisg>
So if you installed ltsp-server-standalone, that might be interfering with your router
10:31
Just run this: sudo apt-get install ltsp-server
10:31
<ballongen>
don't i need to ocnfigure the dhcpserver for it to be activated?
10:31
<alkisg>
(that will just mark it as manually installed)
10:31
<ballongen>
Sorry for my swenglish. :)
10:31
<alkisg>
and: sudo apt-get purge --autoremove ltsp-server-standalone
10:31
(that will get rid of the dhcp3-server)
10:31
<ballongen>
only?
10:31
<alkisg>
No problem, my greeknglish aren't any better :D
10:31
Yes, only those 2 commands, you don't need to rebuild anything
10:32
<ballongen>
sweet
10:32
is the flag --autoremove correct?
10:33
<alkisg>
Maybe it needs an extra dash
10:33
--auto-remove ?
10:33
<ballongen>
doh!
10:33
<alkisg>
(I never remember that one correctly :()
10:33
<ballongen>
ok done
10:34
<alkisg>
OK, go on with the testing, I'll be back in 10'
10:34

13:45jhutchins has quit IRC
13:46
<helmchyn>
in the moment we are running Edubuntu with ltsp, but its a very old installation and i'm convinced debian will be easier to administer
13:46
(well at least for me)
13:46
however
13:46
i've noticed that our low-end thinclients can give a "smoother" x-environment
13:46
when run via XDMCP
13:47
instead of tunneling X via ssh
13:47
is there a way to re-enable ssh-free XDMCP in LTSP-5 ?
13:50
(i'd be happy with a negative answear too, if there is no trivial way i mean)
13:50jhutchins_lt has quit IRC
13:50
<helmchyn>
...because of course there is >some< way ;-)
13:52
<alkisg>
helmchyn: read about LDM_DIRECTX=True in the ltsp manual (see the channel topic)
13:52
I don't think debian will be any easier to administer, it's more or less the same, but go ahead and try it.
13:54
What are your client specs? (ram + cpu)?
13:55
<helmchyn>
alkisg: oh, i did experience heavy problems with ubuntu-release upgrades in the past, and i've been confronted with users who'd like to have more up to date software than the Ubuntu-LongTerm release can provide
13:56
in the moment we use quiet heavy machines, with something like a 1.1GHz Celeron, and RAM downgraded to 64 - 128 MB
13:57
But I'am experimenting with a HP-Thinclient here, which uses some 600MHz Transmeta-CPU
13:57
(which probably could not compete with a Pentium 90)
13:58chupacabra has joined #ltsp
13:59
<helmchyn>
and lets not forget, that a dozend Clients are also some burden to the Server
13:59
...espeacialy with youtube videos running on them and stuff
13:59
<alkisg>
Np - I don't think debian stable will have more up-to-date software than ubuntu though, and I don't think `testing` will be more stable than LTS, as LTS comes from testing + stabilizing... But, since I haven't actually tried debian + ltsp, I can't say for sure
13:59
64MB is the absolute minimum, if you can put 128mb to all of them it'd be better
14:00
Don't look for XDMCP, a LDM_DIRECTX=true in lts.conf is all you need
14:00
<helmchyn>
oh, yeah i think we actually can do that ;-)
14:00
<alkisg>
And a gigabit network is mandatory for videos etc
14:02primeministerp has quit IRC
14:02
<helmchyn>
thank you much for the DIRECTX-Option, exactly what i needed
14:03
you are basically true about most of the software... up-to-dateness.... in Debian
14:03
but
14:04
debian stable is normally uses newer software, than say, a two year old Ubuntu-LTS and I can apt-pin packets from the testing and unstable releases
14:05
while apt-pinning to a newer release in ubuntu.... is not a thing you ever want to do
14:05
too much dependency-foo
14:06
yeah whatever... that's just my opinion
14:06
<alkisg>
I'll pass, I don't think I have the expertise to go to an in-depth comparison of ubuntu vs debian :)
14:06
<helmchyn>
would be wearisome for both of us anyway
14:07
just thought somebody myght care about the pros and cons ;-)
14:07
<alkisg>
I do like the PPAs offered by launchpad though
14:07
They allow me to publish newer software to automatically go to all schools here
14:08
<helmchyn>
yeah, in the moment we run the PPA for OpenOffice
14:09
<alkisg>
We have a central PPA where we copy all the software we need from other PPAs, so that it automatically gets installed to dozens of schools without them changing their sources
14:09
Anyway, debian-policy + apt == magic :)
14:09
I'll leave it to that

I have 35 thin clints on a server, the Server is an i7 CPU, 8 gigs of RAM, Gig NIC and network. the Clients are 100 meg NIC
17:51
when the CLinets login they freeze either during boot up or in an application
17:51Selveste1 has quit IRC

I have looked @ the graphs and Mem CPU and NIC seem very quiet
17:52
Please let me know where I could start looking
