what are the networks called (not ethernet) that clusters are starting to use?
00:05
some crazy new topology/protocol
00:05
<MacIver>
not ethernet?
00:05
<lns>
nope
00:07
<MacIver>
token ring ;)
00:08
<lns>
heh....NO!
00:08
=p
00:09
<MacIver>
coax cable & bnc connectors
00:09
i really haven't heard of anything replacing ethernet, and links?
00:09
*any
00:17
<lns>
it's supposed to be something specific for data center clustering
00:17
some standard or to-be standard
00:22
ahh... InfiniBand
00:22
a proprietary protocol i believe - http://en.wikipedia.org/wiki/InfiniBand
00:22
<MacIver>
ah yeah i've heard of that
00:22
iirc there is support in linux for it
00:23
<lns>
i wouldn't doubt it =)
00:24
The serial connection's signalling rate is 2.5 gigabit per second (Gbit/s) in each direction per connection. InfiniBand supports double (DDR) and quad data (QDR) speeds, for 5 Gbit/s or 10 Gbit/s respectively, at the same data-clock rate.
00:24* lns drools
00:25
<MacIver>
:)
00:25
<lns>
imagine a beowulf cluster of thin clients interconnected by infiniband..they could be the server AND the client! =p
00:26
<MacIver>
yeah!
00:41
well bedtime for me

Hello. Before switching to XDMPC I could assist the users by running `x11vnc -display :6` on the client. Now running them with "SCREEN_07=startx" I can't start x11vnc anymore. Any idea?

Hi all I'am having trouble with my thin client first I can get logged in but I have to manually select the gnome-session on the thin client so that I can login I found out that ltsp doesn't support xgl so that is why i couldn't use the default session is there anyway that I could disable xgl for the thin clients, also when I put cd's or dvd's into the thin I can't play them, they show up but i can't play the dvd and when I open
04:11
they do appear as fuse file systems thought, fun that the cd's show that there is free memory on them when they are cds bought from a shop

goooooooo morning all !
09:39
!seen ogra
09:39
<ltspbot>
ace_suares: ogra was last seen in #ltsp 22 hours, 35 minutes, and 33 seconds ago: <ogra> sure, why not ? it just defines a point in the build process
09:40
<ace_suares>
Hmm... I just installed edubuntu 64 bit, but now in /var/lib/tftpboot/ltsp there is a subdir amd64 and in that are the kernels and initrd...
09:40
does that mean that the TC's have to be 64 bit too. ? Can't imagine.
09:41
When I boot the TC it says 'can't find boot file' during tftp... II think because of that amd64 directory (shouldn't that be i386 ?)
09:42
!seen sbalneav
09:42
<ltspbot>
ace_suares: sbalneav was last seen in #ltsp 1 week, 3 days, 0 hours, 43 minutes, and 44 seconds ago: <sbalneav> What are we looking at?
09:43
<ace_suares>
!seen jammcq
09:43
<ltspbot>
ace_suares: jammcq was last seen in #ltsp 14 hours, 14 minutes, and 56 seconds ago: <jammcq> hey all
09:43
<jammcq>
hmm, haven't seen him around lately
09:44
<ace_suares>
jammcq: he's been away 14 hrs... maybe on a cruise or som'thin
09:44
<jammcq>
what's goin on?
09:44
<ace_suares>
how d' you do jammcq
09:45
oh I just installed 64bit edubuntu
09:45
but now the kernels for the thin clients are 64 bit too
09:45
<jammcq>
yeah, there's an option to ltsp-build-client, to tell it to build a 32-bit chroot
09:46
<ace_suares>
okay, it's interesting tough, because it makes some sense that a 64bit server will have 32bit clients...
09:46
<jammcq>
yeah, seems like a common sense thing
09:46
<ace_suares>
should be an option during install... i'' file a bug somehwere I tyhink
09:46
thanks anyway
09:46
<jammcq>
there was some talk here last week abuot always defaulting to 32-bit clients, as that is likely to be the most common thing
09:47
<ace_suares>
just so you know: I finally found that win4lin will run unde kwm/qemu,
09:47
<jammcq>
ah, cool
09:47
<ace_suares>
(it doesn't run under plain qemu or virtualbox)
09:47
So, now I can have a 32 or 64 bit 'newest' edubuntu (gutsy or hard-on soon)
09:48
and still run a vm with an older, win4ln pathched kernel, that runs win4lin/win98
09:48
I am not so far that I experimented with sound or stuff, and how to connect to the win4lin sessions (vnc ?) but I will just not stop :-)
09:50
Well. if the 64/32 bit issue is al ready discussed, I'll won't bother with a bug report... !
09:57
<Q-FUNK>
hm
09:57
what was the trick to mount /dev/pts again?

Hello, all. Somebody in the past showed me the URL for LTSP5 on Gentoo, does anyone have that URL please?
11:21
<Q-FUNK>
dberkholz might have it
11:21
<vanya>
is he online now?
11:22
<Q-FUNK>
maybe
11:22
probably idling
11:22
<vanya>
dberkholz: can you please provide me the URL with the LTSP5 on Gentoo instructions?

Hello. Before switching to XDMPC I could assist the users by running `x11vnc -display :6` on the client. Now running them with "SCREEN_07=startx" I can't start x11vnc anymore. Any idea? Can I somehow avoid the extra roundtrip and hook in to their sessions on the server instead of on the client's X now?
13:29
<Q-FUNK>
vlt: IIRC there's a tool that allows the admin to view sessions, nowadays, as a part of LTSP.
13:30Q-FUNK has quit IRC

Q-FUNK: Nowadays? Could it be already included into the Ubuntu Dapper LTSP 5 packages?

Q-FUNK: Nowadays? Could it be already included into the Ubuntu Dapper LTSP 5 packages?
13:31
<Q-FUNK>
dapper is old
13:32
I think Gutsy or the upcoming Hardy
13:32
<vlt>
Q-FUNK: I know, but it's the LTS version
13:36makghosh is now known as makghosh|afk
13:38
<Q-FUNK>
vlt: well, I said nowadays. it could not mean a 2-year old release now, could it?
13:40
<vlt>
Q-FUNK: Could have been that everything newer than LTSP 4 is "nowadays" for you ;)
13:41
<Q-FUNK>
rrrrrrrrright.
13:42
anyhow, Hardy will already be much better than Dapper for LTSP support. Lots of inovative features and support for some newer hardware.
13:42
and it's the next LTSP
13:42
ermm.. LTS
13:51
<vlt>
Q-FUNK: Just not in my case :(
13:51
We're using Kubuntu here
13:51
<Q-FUNK>
and?
13:51
<vlt>
and they decided to go for KDE 4 and therefore not declaring it stable enough for LTS
13:53
<Q-FUNK>
hm.. k'
13:53
so they go for KDE4, but they don't put it in LTS?
13:53
what do they put in, then?
13:54
<vlt>
Q-FUNK: Anyway, I think I'll give it a try when it gets ready ...
13:54
Q-FUNK: That's what I read recently ...

Supporting newer hardware sounds fine. I got lots of clients here I only got running in vesa mode.
14:00
<Q-FUNK>
oh?
14:00
why?

Q-FUNK: If you could help me setting the right driver this would be fine of course ;)
14:09
<Q-FUNK>
which hardware?
14:15
<vlt>
Q-FUNK: We nearly solely use HP's t5000 series which has numerous kinds of vga chips built in ...
14:17
Q-FUNK: On some machines xorg's autodetect decides for ati, on others it's via. Sometimes I only get it working with vesa. What can I do to improve this situation?
14:17indradg has quit IRC
14:18
<Q-FUNK>
vlt: HP products are a mess. they keep similar model numbers for products that, in the end, are completely different.
14:18
Hardy might improve things, but... hmm...

Is there a start script that is executed when a user logs in to the server (via XDMCP)? I need to put the client's source IP somewhere for later usage and would try some grep magic on `last` or something liek this ...
