| snaphappi | hi all, I'm having a problem with my ubuntu 8.04.1 ltsp install. | 02:07 |
|---|---|---|
| snaphappi | here is a post that describes the problem: http://ubuntuforums.org/showthread.php?p=5632409 | 02:07 |
| snaphappi | it's the "ipconfig: eth0: SIOCGIFINDEX: No such device" bug, with the Marvell/Sky2 eth controller | 02:08 |
| snaphappi | 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 | 02:08 |
| snaphappi | any ideas? | 02:09 |
| snaphappi | anyone here? | 02:09 |

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