[08:16] <Bert_2> I have checked out the edubuntu handbook, and it tells me a lot about LTSP except which packages I need to use it, so which ones would I need if clients use PXE ?
[13:19] <stgraber> ogra: Looks like we have found the issue in x11vnc. Upstream release handles "broken pipe" correctly but crashes with italc.
[13:19] <stgraber> That happens when we are closing the VNC link before the frame was loaded from the client
[13:19] <stgraber> (so basically closing italc when a student screen is still refreshing)
[13:20] <stgraber> the fact that it's easier to reproduce with larger resolution is probably because it takes longer to refresh than with low resolutions
[13:20] <ogra> yeah
[13:20] <ogra> depending on the bandwith as well i guess
[13:20] <stgraber> indeed
[13:23] <stgraber> we'll certainly have a fix/workaround in final 1.0.9 (if it's released one day :))
[13:23] <stgraber> btw, did you see Richard recently ?
[13:23] <stgraber> I wanted to ask for some news about my cmpc (still not here :( ) but he doesn't seem to be around
[13:39] <ogra> no, i didnt
[13:39] <ogra> not since last wed. or so
[13:42] <stgraber> hmm, ok. I sent him a mail.
[15:10] <RichEd> stgraber: hi
[16:14] <cottima> Hello
[16:15] <cottima> Does Hardy Heron's ltsp5 feature "http boot" from gPXE/etherboot ? (Note:  It has been a year since I have touched LTSP or its docs.  Sorry, just want to know.)
[16:15] <stgraber> what's http boot ? getting stuff using http instead of tftp ?
[16:15] <stgraber> if yes, we don't
[16:16] <cottima> yeah :(
[16:16] <stgraber> why would you do that ?
[16:17] <stgraber> it sounds like it'll need a lot more resource than the simple tftp deamon we have. And you'll need gPXE to use it so won't work with standard PXE rom
[16:18] <cottima> stagraber It transfers the image faster (tcp over udp).
[16:21] <stgraber> ah, I should go back to reading about network protocols :), in my memory udp should be faster as it doesn't require ack/signature as tcp does ...
[16:21] <cottima> stgraber http://www.linux.com/feature/118636 has three flash videos that talk about some new gPXE features.  I am a lazy, dumb linux [desktop] user, so it sounds good to me.  However, I need more maturing before implementing something.
[16:22] <cottima> stgraber, I thought what you said is what was say in my networking class, but...
[16:24] <stgraber> I guess Ubuntu won't install a http server with all LTSP installations until "http boot" is supported by the PXE chips on motherboard. Only a few users are using gPXE to boot their clients.
[16:24] <stgraber> that said, you probably can just install apache or lighttpd, set the web directory to /var/lib/tftpboot and it'll probably work fine
[16:44] <cottima> thanks stgraber
[18:01] <Lns> In a dual-NIC edubuntu setup, should a certain NIC be brought up by /etc/network/interfaces first? I'm having an issue where i have to cycle eth0 and eth1 whenever the system is rebooted - as it is now, eth0 is brought up first (eth0 is the "to-the-wan" iface).
[18:01] <Lns> For whatever reason, it can't see the rest of the world (can't ping out) until I cycle the NICs after reboot - the interfaces file is in correct syntax, too.
[18:02] <Lns> (minus a broadcast stanza for each NIC that i just put in...)
[18:32] <aarmelvin> ?
[18:35] <aarmelvin> anybody know how to use jabbin client
[18:36] <Lns> aarmelvin, ?
[18:37] <Lns> ah
[18:37] <Lns> voip for jabber? Cool!
[18:37]  * Lns has never personally heard of it before, so...no. ;)
[18:37] <ogra> Lns, i'm not sure we still support /etc/iftab but you could assign a fixed devicename by MAC there
[18:39] <Lns> ogra, do you think it's an issue of which one is brought up first? Because the interfaces man page says whatever one is listed in the interfaces file is brought up first...
[18:39]  * Lns hasn't even heard of /etc/iftab ;)
[18:39] <ogra> Lns, /etc/udev/rules.d/70-persistent-net.rules should fulfill the same purpose though
[18:40] <ogra> make sure to set ATTR{address} and NAME
[18:41] <aarmelvin> can i login into jabbin using my gmail account
[18:41] <Lns> ogra, what purpose to fulfill ? I'm not following the reason to use /etc/udev/rules.d/70-persistent-net.rules or /etc/iftab
[18:41] <aarmelvin> i got the error message saying that "connection failed:unable to connect with the server"
[18:42] <aarmelvin> anybody resolve my problem
[18:42] <ogra> Lns, to assign a fixed device name (ethX) to a certain NIC
[18:42] <Lns> aarmelvin, I don't think this is the correct channel to ask that question
[18:42] <aarmelvin> k...sorry
[18:43] <Lns> ogra, so you think the problem is that the NICs are getting mixed up during boot, based on what I said before?
[18:43] <aarmelvin> bye
[18:43] <ogra> Lns, you said that
[18:43] <Lns> well I just said I had to cycle up/down my NICs after boot
[18:43] <ogra> oh
[18:43] <Lns> because I can't ping outbound (via eth0)
[18:43] <ogra> i thought you had to cycle the names
[18:44] <Lns> oh no
[18:44] <ogra> thats weird then, the order they are brought up in shouldnt matter at all
[18:44] <Lns> ok
[18:44] <ogra> can you pastebin your /etc/network/interfaces ?
[18:44] <Lns> I know I've had issues before, even with an old server at the same location (if it can't reach a DNS server it will time out and nobody can boot TCs)
[18:45] <Lns> sure
[18:46] <Lns> !pastebin
[18:46] <Lns> ogra, http://paste.ubuntu.com/22387/
[18:47] <ogra> hmm, nothing suspicious in there
[18:48] <Lns> ogra, bah - maybe my resolv.conf was fudging it up - its first entry was a bogus DNS server (not reachable)
[18:48] <Lns> think that would do it?
[18:48] <Lns> I know I've had weird issues with DNS and LTSP before
[18:48] <ogra> you could just add dns-nameservers to the interfaces file
[18:48] <Lns> (if DNS isn't reachable at boot or becomes unreachable)
[18:50] <Lns> ogra, weird, i don't see that in the man page for interfaces
[18:50] <ogra> oh, thats resolvconf, sorry ignore that
[18:51] <Lns> ah
[18:51] <Lns> ;)
[22:47] <stgraber> ogra: yeah, we found the issue in iTalc. It's actually an upstream x11vnc bug when using tight encoding. We'll just disable it for now until it's fixed upstream.
[23:28] <Lns> stgraber, which issue is that?
[23:32] <stgraber> ica crashing randomly
[23:43] <Lns> stgraber, ah...you wouldn't happen to know anything about Gnome themes cycling randomly with VNC in Hardy, would you?
[23:44] <stgraber> hmm, no, never heard of that
[23:44] <Lns> stgraber, https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/239342 if you're interested..I filed that one
