Sorry to hijack this thread, but my question relates and the people responding 
to this thread seem to understand the two-nic networking issues.

My current setup (I used to need this because I was using my Kubuntu machine 
as an internet router/firewall for the rest of the network)

eth0 -> lan -> wired to hub -> name resolution via /etc/hosts
eth1 -> internet -> wired to combo DSL modem/router/ hub -> name resolution 
via dhcp server on modem/router/hub

My current needs (to remove redundancy of the single purpose hub and use the 
combo modem/router/hub for both internet and lan traffic, and to thereby 
simplify the vmware client access to both networks)

The modem/router/hub allows me to turn off dhcp, but I don't see the reason to 
if I can change the kubuntu lan settings to use dhcp instead of /etc/hosts

Also, I must mention that the lan is all samba.  Two windows computers, a Mac, 
and this Kubuntu Dapper machine.  If I switch to dhcp for the local network, 
how will smb name resolution work?
