Hi
Use wireshark (ethereal) to do a packet capture with the firewall on,
then do one with the firewall off to see what is happening.

The only way I have been able to do it is to turn off the firewall.
It's a known bug that has been around since the beginning of the firewall,
fixed in one version of 9.3 and back again in all 10.x versions including
10.3 Beta3. See Bug #243809 at
https://bugzilla.novell.com/show_bug.cgi?id=243809
It does have some suggestions.

I would rather do things a different way, like usb flash (and keep the
firewall intact) or something to eliminate the data being made Win
compatable and then changed back to Linux compatable. It works, buy why
not a direct Linux-Linux LAN transfer without all the Win smb stuff? I'm
eliminating Win boxes everywhere possible, so I may soon not even need smb
and other 'fudge it down to their level' stuff.
