| 00:04 | <lns> 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

| 03:24 | <vlt> 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?

| 04:10 | <Furlow> 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

| 09:39 | <ace_suares> 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?

| |
| 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?

| 13:27 | <vlt> 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.
| |
| 13:30 | Q-FUNK has quit IRC | |
| 13:31 | <vlt> Q-FUNK: Nowadays? Could it be already included into the Ubuntu Dapper LTSP 5 packages?

| 13:31 | <vlt> 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
| |
| 13:36 | makghosh 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 ...
| |
| 13:54 | sepski has joined #ltsp | |
| 13:56 | <vlt> 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?

| 14:07 | <vlt> 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?
| |
| 14:17 | indradg 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...
| |
| 14:18 | Q-FUNK has quit IRC | |
| 14:19 | <vlt> Yes, I had to realize this :(

| 14:36 | <vlt> 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 ...
