[plug] smb client timeout problem

[Steve Boak]

Hi all

I'm getting weird results trying to mount smb shares from one linux box to the 
other. Both machines are running Debian Testing with  sambd 3.0.20b-Debian, 
Kernel 2.6.12.2 on the server and 2.6.14.1 on the client.

My 'client' machine is dual-boot, and with windows-2000 I can access all the 
server shares with no problems at all.

When I boot the client machine into Linux, I get the I/O timeouts trying to 
use a mounted smb share on the server.

Since I have samba running on both machines, I tried it the other way - ie 
if I try to mount a share from the client onto the server, I get the same 
problem. So it seems to be something to do with smbfs mount, not the server,  
and probably the 'testing' version, but I am at a loss as to where to look 
next.

Hmm, just tried something else - mounting the same smb share from the server 
locally (on the same machine) - it mounts, but I can't access it there 
either!

Google throws up a few similar errors and a couple of config changes, but no 
conclusive fixes. Using the cifsfs file system instead of smbfs is mentioned, 
but I haven't looked into that yet.

Examples:

shuttle:/home/steve# mount -t smbfs -o username=steve //min/download /mnt/tmp
Password:
shuttle:/home/steve#

seems the mount went OK...

shuttle:/home/steve# mount
[...]
//min/download on /mnt/tmp type smbfs (rw)

But...

shuttle:/home/steve# ls /mnt/tmp
ls: /mnt/tmp: Input/output error
(exactly 30 seconds to timeout - is this significant?)

Various log file contents:

/var/log/samba/log.smbmount on the *client* shows this:

Any ideas?
