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? :-)

<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

<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
08:00Nick 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

vfat|iso9660|ntfs) LOCALDEV_MOUNT_OPTIONS=${LOCALDEV_MOUNT_OPTIONS:-"defaults,utf8"} ;;
08:10
That line?
08:10Nick 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)

08:28
<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

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

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!
