I've looked through the emails for the last couple of weeks. Could you
provide me the message id?
They are a mix of good and bad information.
Here are my findings this morning (rather long):
----------------------------------
This is a report straight after a terminal reboot.
part 2:
~> ps -ef | grep lbus
1009 root 1616 S /sbin/lbuscd
...
~> ls -l /tmp/drives
shows both readonly and readwrite
part 3:
~> hostname
orophin
part 4:
USB is detected, might take a few plugs to get it mounted, after which we have
the following entry in /etc/fstab
/dev/scsi/host1/bus0/target0/lun0/part1 /tmp/drives/Removable_Device_244_Mb
auto rw,noatime 0 0
part 6:
~> id
... groups= ..., Number (fuse)
part 7:
~> ps -ef | grep lbussd
testuser 16405 16380 0 10:59 ? 00:00:00 /usr/bin/perl -w
/usr/sbin/lbussd
testuser 16626 16580 0 11:00 pts/5 00:00:00 grep lbussd
part 8:
~> /sbin/lsmod | grep fuse
fuse 42008 6
~> ls -l /dev/fuse
crw-rw---- 1 root fuse 10, 229 Apr 27 21:20 /dev/fuse
part 9:
~> echo $DISPLAY
orophin:0.0
part 10:
After running
/usr/sbin/lbus_event_handler.sh add block /tmp 1024 Temp
~> cd Drives
~/Drives> ls -l
total 0
drwxr-xr-x 2 testuser stud 0 May 18 2006 readwrite
?--------- ? ? ? ? ? tmp
~> mount | grep ltsp
ltspfs on /RAID_SERVER/testuser/Drives/readwrite type fuse
(rw,nosuid,nodev,user=testuser)
ltspfs on /RAID_SERVER/testuser/Drives/tmp type fuse
(rw,nosuid,nodev,user=testuser)
doing a 'remove' removes the 'tmp' again
---------------------
Just as a test I try to manually do what lbus_event_handler.sh does, by hand:
[EMAIL PROTECTED]:~> mkdir $HOME/Drives//tmp
[EMAIL PROTECTED]:~> ls -l Drives/
total 4
drwxr-xr-x 2 testuser stud 0 May 18 2006 readwrite
drwx------ 2 testuser stud 4096 May 18 11:10 tmp
[EMAIL PROTECTED]:~> /usr/sbin/ltspfs orophin:/tmp/drives//tmp "$HOME/Drives//tmp"
[EMAIL PROTECTED]:~> ls -l Drives/
total 0
drwxr-xr-x 2 testuser stud 0 May 18 2006 readwrite
?--------- ? ? ? ? ? tmp
[EMAIL PROTECTED]:~> fusermount -u -z

total 4
drwxr-xr-x 2 testuser stud 0 May 18 2006 readwrite
drwx------ 2 testuser stud 4096 May 18 11:10 tmp
But I can get access to /tmp on orophin by using
[EMAIL PROTECTED]:~> ls -l Drives/

There are no error messages at all.
Second login
------------
Floppy is detected, cdrom does not spin up and does not get detected,
USB is detected by udev on the terminal (acording to /var/log/messages
on the server) is not mounted on the desktop.
The contents of ~/.lbussd.out states
fifo opened, fd: 4
Sending: Register
Sending: EnumerateDevices
Starting the loop...
listening on: 3
event: [AddBlockDevice|2|1|readwrite|0|0|Floppy], messagetpe: [AddBlockDevice]
Saved:
device_id: 1
sharename: readwrite
removeable: 0
size: 0
desc: Floppy
type: block
About to run /usr/sbin/lbus_event_handler.sh
and nothing more, no events when plugging a USB.
As for part 6 through 10, the results are the same as above.
Third login
-----------
No floppy, no reaction to USB or CDROM
~/.lbussd.out says:
fifo opened, fd: 4
Sending: Register
Sending: EnumerateDevices
Starting the loop...
listening on: 3
step 6 through 10 as above
--------------
Dropping out of X and back to the shell on the terminal show that
it finds and mounts the USB just fine.

Here is an interesting one for you:
(this is on the fourth login if it matters)
There are not floppy as mentioned above, but if I manually run
/usr/sbin/lbus_event_handler.sh add block readwrite 1024 Floppy
I do get access to the floppy on the terminal.
----------------
So now you know why I'm so confused. As mentioned, every thing works
just fine, for the first user after a reboot.
No I have not tried sshfs or the example fuse filesystem. I'll try the
last one after lunch.
Could it matter that I took the latest version of fuse from
sourceforge, and used that for installing the fuse libs, that might
not be the same version as is used in the kernel code (I do not know how to
check this)
