I assume you specified the ATM interface in smb.conf?  With two (or 
more) ethernet interfaces, samba binds to the first one (ie, eth0) 
without any interface parameter in the smb.conf file.  If you want 
samba to see more than one, you must specify them explicitly.  If 
that doesn't work, is there some way to get the ATM interface to 
look like eth0?

That's all I could think of - Steve

The salesman said "This machine requires Windows 95, NT, or
better."   The only thing I could think of was Linux.
