Public bug reported:
A user found it hard to share files on an external hard drive. Although
it is not clear which package to file the bug against, I guess samba is
a reasonable starting point.
The user wanted to share files on an external usb hard drive. nautilus-
share made that part easy, except that when I tried to access the share,
I got a not-very-helpful generic error message from nautilus.
So I tried to use smbclient directly, and got only
NT_STATUS_BAD_NETWORK_NAME errors, even though 'smbclient -L' revealed
the share existing normally.
After checking the samba log on the user's laptop it appeared that the
shared path (/media/USB-DISK) did not exist! But it certainly did.
Eventually I realised that the problem was that the 'nobody' user could
not access /media/USB-DISK because hal's default policy is to mount
disks so that they are only readable by the mounting user.
So the next step was to add the mount options 'fmask=111,dmask=000' to
the volume, which was ok to do in nautilus, and then remount the disk.
But I still got NT_STATUS_BAD_NETWORK_NAME errors on the client. I
thought that maybe I would have to restart samba to persuade it to try
and look in /media/USB-DISK again, but that didn't work--and then, the
share disappeared from the output of smblcient -L entirely!
At this point I ran 'net usershare list' on the server and got the
following output:
info_fn: file /var/lib/samba/usershares/blah is not a well formed usershare
file.
info_fn: Error was Path not allowed.
Hm, not very clear. At this point I gave up and began to write this bug
report.
Meanwhile, my user rebooted, and then examined the share properties in
nautilus. Now, they got an error saying that the share would not work
because 'usershare owner only' needed to be set to false. After changing
the option and restarting samba, I was then able to access the share.
Phew!
So I think there are a couple of different bugs here:
1. Unclear error messages from samba if it is unable to access a shared
directory
2. No warning from nautilus-share if samba can't access a shared directory
3. nautilus-share did not recognise that the situation had changed and did not
present the useful message until the user had restarted
