[wellylug] Samba & DHCP config ?

[Roger Young]

Yes, I understand that about the router, but the router
is also a switch, or hub or whatever, for the LAN. So I need
to know (and Samba needs to know) how to address the local
machines. If the router employs dynamic IP addressing
then it seems difficult to use these same IP numbers for local
ethernet traffic. I think Ian Sterling has the key: 

>netbios name = machine_name

in smb.conf. So I don't need to use an IP address, the machine
name will do. I'll try this tonight (thanks Ian)

Cheers,
Roger
