Thanks Chuck, I had a chance this evening to test with the Hardy alpha 4
live CD and indeed, I no longer see the kernel oops. The kernel oops I
used to get is below.
So the workaround mentioned in the Debian bug report now works. Changing
my /etc/auto.smb as follows enables me to connect to my Ubuntu Samba
server with autofs:
--- /etc/auto.smb 2007/03/29 15:27:45 1.1
+++ /etc/auto.smb 2008/01/18 16:08:28
@@ -24,6 +24,7 @@
mountopts="$mountopts,credentials=$credfile"
smbopts="-A $credfile"
else
+ mountopts="$mountopts,sec=none"
smbopts="-N"
fi
So "mount.smb -o guest" works:
ket% sudo mount.smb //mog.local/share /mnt -o guest
Anonymous login successful
ket%
- but "mount.cifs -o guest" does not work:
ket% sudo mount.cifs //mog.local/share /mnt -o guest
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)
ket%
- but "mount.cifs -o sec=none" does work:
ket% sudo mount.cifs //mog.local/share /mnt -o sec=none
ket% ls /mnt
Movies MythVideo
ket%
So, *should* "mount.cifs -o guest" work like "mount.smb -o guest", or should
/etc/auto.smb use "sec=none"?
Much thanks for all your help with this issue Chuck, Jack
