| 07:16 | <Hyperbyte> I have a DVD-RW USB drive which I use for LTSP. There are certain CD's it has trouble mounting. Not sure what's different about the CD's though.
| |
| 07:17 | I have one right now, if I connected the USB DVD-drive to a Windows it brings up dialog for it nearly immediately
| |
| 07:17 | On the LTSP it doesn't appear as a localdevice. When I try to manually mount it, it says device is busy or already mounted
| |
| 07:17 | Anyone got any pointers? :-)

| 07:39 | <alkisg> Hyperbyte: I think a small change is needed in the ltspfs udev rules for UDF volumes, but I don't remember the details - check the irc logs, I think we helped someone troubleshoot this some months ago
| |
| 07:48 | <Hyperbyte> Tell me I can search the logs....?
| |
| 07:48 | As in, enter parameters and it'll tell me where? :P
| |
| 07:49 | Ah, Google indexes the logs... that makes it easy. Any recommendations what I should search for? :-)
| |
| 07:54 | <komputes> alkisg: which lts.conf? /var/lib/tftpboot/ltsp/i386/lts.conf or /opt/ltsp/i386/etc/lts.conf? keep in mind I am using Ubuntu 10.04.
| |
| 07:55 | <Hyperbyte> The first one
| |
| 07:56 | gnunux (~emmanuel@194.167.18.244) left irc: Quit: Ex-Chat | |
| 07:57 | <komputes> thanks Hyperbyte and alkisg. I thought, after reading the manual that I would have to put more than that:
| |
| 07:57 | CONFIGURE_X = True
| |
| 07:57 | X_CONF = /etc/X11/my-custom-xorg.conf
| |
| 07:57 | XSERVER = nv
| |
| 07:57 | <alkisg> Hyperbyte: google for: "udf site:nubae.com"
| |
| 07:57 | komputes: no, you don't have to put those
| |
| 07:57 | CONFIGURE_X is deprecated
| |
| 07:57 | XSERVER isn't used if you use a specific X_CONF file
| |
| 07:57 | But remember to put [Default] on top of lts.conf
| |
| 07:58 | <komputes> alkisg: I don't have defaults
| |
| 07:58 | <alkisg> You need to put that on top, otherwise it's a syntax error
| |
| 07:58 | <komputes> alkisg: thought it was auto. so just [Default] (no need defining it?)
| |
| 07:59 | <alkisg> No, it's not automatic, it's a syntax error
| |
| 07:59 | Yes, just [Default]
| |
| 07:59 | <komputes> ok, thats probably why it doesn't work
| |
| 07:59 | thanks alkisg
| |
| 07:59 | <alkisg> See the exact lines I wrote when I first answered you
| |
| 07:59 | <Hyperbyte> alkisg, I did... there's something about fstab entries, but I don't think that's relevant with ltspfs?
| |
| 07:59 | <komputes> alkisg: yup, thats what I had
| |
| 08:00 | Nick change: Parker955 -> Parker955_Away | |
| 08:05 | <alkisg> Hyperbyte: is the problematic CD a UDF cd, instead of an iso9660 one?
| |
| 08:05 | <Hyperbyte> How do I check?
| |
| 08:06 | <alkisg> sudo fdisk -l ? Or sudo blkid
| |
| 08:06 | Or "mount"
| |
| 08:06 | (after inserting the CD on e.g. the server, or on another standalone linux machine)
| |
| 08:07 | <Hyperbyte> Well it doesn't auto-mount on the LTSP thin client
| |
| 08:07 | It actually says buffer I/O error on device sr0 now when I try to mount it
| |
| 08:08 | Now it mounts, but says udf: udf_read_inocde(ino ##) failed !bh
| |
| 08:08 | <alkisg> OK, it's a udf one.
| |
| 08:08 | <Hyperbyte> I guess that answers the question, yeah. :)
| |
| 08:08 | Despire the errors, now it did mount and I can read from it.
| |
| 08:08 | *Despite
| |
| 08:09 | <alkisg> In /opt/ltsp/i386/lib/udev/ltspfs_entry, there's a function add_device
| |
| 08:09 | Search for iso9660. You'll see that it *doesn't* have a check for UDF volumes there
| |
| 08:10 | Maybe adding udf there will solve the problem
| |
| 08:10 | staffencasa (~staffenca@128-193-145-254.oregonstate.edu) joined #ltsp. | |
| 08:10 | <Hyperbyte> vfat|iso9660|ntfs) LOCALDEV_MOUNT_OPTIONS=${LOCALDEV_MOUNT_OPTIONS:-"defaults,utf8"} ;;
| |
| 08:10 | That line?
| |
| 08:10 | Nick change: Parker955_Away -> Parker955 | |
| 08:11 | <Hyperbyte> Should make it vfat|iso9660|ntfs|udf) ... etc?
| |
| 08:13 | <alkisg> Hyperbyte: ah, found it. See this: http://bazaar.launchpad.net/~ltsp-upstream/ltspfs/ltspfs-trunk/revision/148
| |
| 08:13 | cdpinger.c needs to be modified
| |
| 08:13 | I.e. the problem was solved in later ltspfsd versions
| |
| 08:15 | <Hyperbyte> Okay....
| |
| 08:15 | So... how do I get the later ltspfsd version on Edubuntu 11.04?
| |
| 08:15 | <alkisg> It's not available yet, so you need to compile it yourself
| |
| 08:15 | <Hyperbyte> I had a feeling I wasn't gonna like the answer. =D
| |
| 08:15 | Any workarounds?
| |
| 08:16 | <alkisg> It's not that hard. I've got some work to do so here are some tips to get you going:
| |
| 08:17 | bzr branch lp:~ltsp-upstream/ltspfs/ltspfs-trunk
| |
| 08:17 | sudo apt-get build-dep ltspfsd
| |
| 08:17 | debuild -b -tc
| |
| 08:17 | Those should get you an ltspfsd.deb to install
| |
| 08:17 | Ah you'll also need the /debian directory from the ubuntu package:
| |
| 08:18 | apt-get source ltspfsd ==>and get /debian from it
| |
| 08:18 | That should be it - bbl
| |
| 08:19 | (or, wait until ltspfsd 0.8 lands on oneiric, and get the .deb from there)
| |
| 08:21 | NeonLicht (~NeonLicht@darwin.ugr.es) joined #ltsp. | |
| 08:28 | <Hyperbyte> To be honest, the last sounds like a favorable option. Any idea when that could be though?
| |
| 08:28 | Because if it takes months I don't think I can afford to wait.
| |
| 08:29 | (gotta go home, will read later)
| |
| 08:29 | <alkisg> No idea, ask stgraber

| 09:51 | <muppis> Guys, you miss something special. It is about last times for this summer when sun doesn't set at all.
| |
| 09:52 | But getting more beer.. Have fun.
| |
| 10:08 | <komputes> alkisg: It's still not working. Do I need to rebuild the chroot image after a change to lts.conf?
| |
| 10:12 | <vagrantc> komputes: you should probably be editing /var/lib/tftpboot/ltsp/lts.conf, which doesn't require rebuilding
| |
| 10:15 | <komputes> vagrantc: ok, I'll try, I was using /var/lib/tftpboot/ltsp/i386/lts.conf
| |
| 10:21 | <alkisg> komputes: sit on a client. Login. Open gnome-terminal. Run: ltsp-localapps xterm
| |
| 10:21 | An xterm will open. That xterm is special, it runs locally. Inside it, run: getltscfg -a
| |
| 10:21 | This will tell you if the client reads lts.conf or not.
| |
| 10:22 | komputes: /var/lib/tftpboot/ltsp/i386/lts.conf is indeed the correct path, vagrantc just made a typo above
| |
| 10:23 | <vagrantc> oops
| |
| 10:23 | sorry about that
| |
| 10:27 | <komputes> alkisg: I can't start the terminal completely because X doesn't work
| |
| 10:31 | alkisg: I just get a black screen after PXE booting
| |
| 10:34 | does "X_CONF = /etc/X11/my-custom-xorg.conf"have to be indented?
| |
| 10:38 | <alkisg> komputes: no, it doesn't have to be indented. Put the following in lts.conf instead, to verify that your client reads it:
| |
| 10:38 | [Default]
| |
| 10:38 | SCREEN_07=shell
| |
| 10:39 | Reboot the client, and see if you get a text console
| |
| 10:50 | frederickjh (~frederick@rivendell/member/frederickjh) joined #ltsp. | |
| 10:51 | <frederickjh> I am updating my client image and ran into the following question about nbd-client.
| |
| 10:52 | When the nbd-client init script is called to stop the nbd-client service, there are two things that can be done: either it can disconnect all nbd-client devices (which are assumed not to be in use), or it can disconnect only those nbd-client devices that it knows about in its config file. The default (and the traditional behavior) is to disconnect all nbd-client devices. If the root device or other critical file systems are on NBD this
| |
| 10:52 | Anyone know the correct answer?
| |
| 10:53 | Or at least what the nbd-client does in relationship to ltsp?
| |
| 10:54 | This is on Ubuntu Lucid 10.4 LTS
| |
| 10:59 | No is selected in the configuration dialog. Can I assume that that is the current configuration?
| |
| 11:33 | <alkisg> frederickjh: just press [enter] there, it doesn't matter for ltsp anyway
| |
| 12:01 | <frederickjh> Thanks alkisg!
