[02:07] hi all, I'm having a problem with my ubuntu 8.04.1 ltsp install. [02:07] here is a post that describes the problem: http://ubuntuforums.org/showthread.php?p=5632409 [02:08] it's the "ipconfig: eth0: SIOCGIFINDEX: No such device" bug, with the Marvell/Sky2 eth controller [02:08] if I put in a 2nd Realtek PCI eth controller, the client boots fine. but I can't get the client to PXEboot from the Realtek [02:09] any ideas? [02:09] anyone here? === michiel_e is now known as Eghie === biabia is now known as [biabia] [13:37] question: does anyone here have experience configuring ltsp server?

[13:39] hi all, I'm having a problem with my ubuntu 8.04.1 ltsp install. it's the "ipconfig: eth0: SIOCGIFINDEX: No such device" bug, with the Marvell/Sky2 eth controller. if I put in a 2nd Realtek PCI eth controller, the client boots fine. but I can't get the client to PXEboot from the Realtek. can anyone here help? [13:41] snaphappi, might be that the sky2 module is missing from initramfs's netboot code [14:19] snaphappi: if you want the clients to boot from the other controller, edit /etc/default/dhcp3-server and set it to eth1 [14:22] nah [14:22] file a bug on initramfs-tools with the exact module name so it gets added to the default set :) [14:24] think the sk2 driver has known problems in kernel [14:51] Hi all [14:57] When I login to edubuntu I get a message that he ISD-server could not be started because port 5800 is already in use. I see a lot of reports of this when I did a google search but no solutions (other then just getting rid of the message box) [14:59] are you using kde ? [14:59] no, xfce [15:00] I just found out that its italc [15:00] ok, do you have multiple sessions open at the same time ? [15:00] nope [15:00] are you using some session saving feature ? (your programs are restored when you open your session) [15:00] nope [15:01] I removed italc and it solved the issue [15:01] this error message appears when italc is started multiple time, it can only happens in one of these two scenarios [15:01] hrm [15:02] well it does [15:02] this problem has been solved in the version we currently have in Intrepid, if you want italc to work in Hardy the same way it does in Intrepid, we have a PPA with the package for Hardy [15:03] its ok, I wasn't planning on using italc anyway [15:03] :) [15:06] morning all [15:07] morning sbalneav [15:07] hi sbalneav [20:09] !help [20:09] Hi! I'm #edubuntu's favorite infobot, you can search my brain yourself at http://tinyurl.com/5zfb6t - Usage info: http://wiki.ubuntu.com/UbuntuBots [20:10] Eghie: Hello [20:10] sbalneav: hello [20:10] how are you doing? [20:22] sbalneav: do you know a way to measure how much clients a LTSP server can handle? [20:23] what I can do is boot the whole office from LTSP to check if it can handle it [20:24] but better would be a good benchmarking tool, which gives me some numbers, so I directly can see what effect changes have on the server [20:25] Well, as usual, the answer is always: "It depends" [20:25] hehe [20:25] yeah, average usage of the clients, network speed, how much downloads, etc [20:25] If all you're going to do is log in and open up a telnet window, then lots and logs [20:25] yes I know [20:26] The edubuntu handbook has some sever sizing guidelines [20:26] !handbook [20:26] The Edubuntu Handbook is currently work-in-progress and can be browsed via http://doc.ubuntu.com/edubuntu/handbook/C/ [20:26] average student (primairy school) [20:27] nice handbook :) [20:29] where do you find the sizing guidelines? [20:30] does anyone here perhaps use fingerprinting authentication in their labs [20:31] coolio: no, we do have some fingerprinting plans and also some fingerprinting keyboards from IBM [20:31] or maybe has some info on it for ubuntu/debian/etc [20:31] there was a pam module for fingerprinting [20:31] although, It would be nice to use it via the network [20:32] the pam module reads an USB disk [20:32] then you need something like USBIP to let it communicatie via the network [20:32] Eghie: a url link for more info [20:32] anyone have a server hanging with "starting gnome display manager" ? [20:33] I'm stuck right now [20:33] Eghie: http://doc.ubuntu.com/edubuntu/edubuntu/handbook/C/server-hw.html [20:33] have a whole school down [20:33] monteslu: What does ps show? [20:33] Home dirs local or nfs mounted [20:33] sbalneav: where I would expect it, thanks (didn't find it though) [20:33] sbalneav, I can't log in [20:33] might have a tanked nfs server [20:33] i'm using ldap [20:33] but I cant get passed that part [20:34] can you ssh in from a full workstation? [20:34] nope [20:34] i can ping it [20:34] but i can't authenticate [20:34] Log in on the console? [20:34] nope [20:34] Not even as the local admin user you set up when you installed? [20:34] and if i try and go in via safe mode it ignores my requests to go in as root [20:34] oh, maybe that one [20:35] get in? [20:40] still not yet [20:40] before i moved it over to ldap i think was probably just using /etc/passwd or shadow or whatever [20:40] but I can't remember the account I used [20:41] and apparently root is bad to ubuntu or something [20:42] I really wish I could see the events firing up like i do in redhat [20:42] I'm not 100% certain where its hanging right now [20:42] in safe mode it hangs on "starting gnome display manager" [20:44] in regular mode if I ctl-alt-f1, it's hanginn on "kinit: no resume image doing normal boot..." [20:44] sbalneav, is there a param i can pass in grub to see the boot messages to better debug what's happening? [20:45] yup [20:45] I'm edubuntu 8.04 btw [20:45] when you see the grub notice, hit esc [20:46] You'll want to 'e'dit the kernel boot line, remove the "quiet splash" bit at the end [20:46] then 'b'oot that kernel line. [20:46] awesome [20:47] did you just convert to ldap auth? [20:49] about a month ago [20:49] things just went bad on friday [20:50] looks like same problem with starting gnome display manager [20:50] but it also has trouble binding to ldap right after boot [20:51] my ldap server is able to ping the ltsp server without issues, and I was authenticating just fine friday [20:51] oh, btw sbalneav. While I've got you here. Why do we need to put users in a group for local devices to work? Can't it just work for everyone? [20:57] It can [20:57] You just have to modify a udev rule [20:58] Well, I'd say the problem is the bind to ldap. What's your ldap server, openldap? [20:58] sbalneav, yeah. It'a ancient. FC5 [20:59] Was thinking about moving it to centos 5 or 8.04, but smbldap is dead :( [21:01] Funny thing is, These two new servers I have could probably handle the load of seventy thin clients without my moving the users off so I could have 2 ltsp servers [21:02] ok, so you're using libpam-ldap to bind? [21:02] Any clues in the message logs where the problems are? [21:02] I just got kicked. I'm thinking it might be the network now [21:03] two new gigabit dell switches [21:03] but they've been most working for a month [21:03] maybe I can boot with a sysresccd to view the logs [21:04] sbalneav, is there a way to individually launch services? In redhat. I could hit 'I' during boot and it would ask me Y/N to launch each [21:05] i know theyre not sequential in ubuntu though [21:08] That I'm not sure of [21:09] perhaps the "starting gnome..." gets stuck and it has dependant processes. [21:09] Typically what I do is modify the boot command line to include the -s (single user) and then start the services one by one [21:10] Are you using libnss-ldap? [21:10] monteslu: starting gnome... will not say it IS starting gnome [21:10] sometimes it is saying that and using something totally different [21:13] What I do these days is not use libnss-ldap, but rather install liblnss-db, and use the nss-updatedb package [21:13] I set up a cron job to update the local copies of group and passwd. [21:14] I've found libnss-ldap to be flaky, and, if you have a situation where you are now, it generally fubars the box [21:14] but with the libnss-db, the copy's local [21:15] sbalneav, yeah libnss [21:16] ok, sorry guys. Just found out my ldap server is hosed [21:16] for some reason I thought it was fine [21:16] but I think my database is trashed [21:16] normal recovery steps aren't fixing it either [21:17] this isn't an ubuntu ltsp, or gnome problem [21:17] though not sure why gnome hangs when ldap server is down [21:18] Well, it's probably trying to look up group info [21:18] and since libnss- is hoszed [21:18] it's hanging [21:19] monteslu: Got an ldif dump of it you can reload? [21:19] I wonder if there's a way to back openldap with mysql instead of berkley [21:19] I think so [21:19] sbalneav, nothing recent :( [21:19] Oooh [21:19] well, I didn't lose home dirs which is good, but I so don't want to rebuild that thing [21:20] I have to go to my normal job tomorrow which means I'll be up all night fixing this thing [21:21] I sent you my nightly slapcat script [21:21] via private msg [21:37] my slapd_db_recover seems to be working, but restarting ldap fails... [21:37] I'ts gonna be a long night [21:37] sbalneav, any suggestions on building a new ldap server for my 2 ltsp servers? [21:37] 8.04? [21:37] I'm not even worried about the samba part anymore. [21:38] i gave up hope on it being my domain controller / linux homes [21:39] my win2003 terminal server will remain standalone for users [21:47] We're running an older 6.10 box for ldap [21:48] it needs to be updated, but I can't see why 8.04 wouldn't be OK for openldp [22:12] my googling tells me that that i can recover everything _but_ dn2id and id2entry bdb files [22:12] this really, really bites [22:13] it is so easy to corrupt berkely databases [22:15] Depending on how many entries you have, I think there's a plaintext backend, isn't there? [22:15] Little slower than db, but vi-editable [22:17] the bdb file looks almost plain text [22:18] i really wish slapd_db_recover would fix it or tell me if it can't. It just finshes like everything is cool. But then ldap doesn't start because it thinks id2entry.bdb is corrupt [22:20] monteslu: Hmm, a "shell" backend [22:24] a backend that doesn't try to cache transactions [22:24] something that just commits changes to whatever its datastore is when it happens [22:24] if it crashes, oh well [22:24] just start back up [22:47] google slapd_db_load or slapd_db_dump [22:47] absolute joke [22:47] nobody beside the author must have any idea what those things do [22:47] compeletely undocumented [23:52] what's the command to build the /opt/ltsp stuff after a new install ? [23:54] sudo ltsp-build-client
