How do I tell orbit to use eth0/tcp?

[Code11Smith007 aol com]

My orbit server is now using lo interface but I want to run my client and 
server on different machines using tcp or udp.

The .orbitrc in /root dir  on server contains:

ORBIIOPUSock=0
ORBIIOPIPv4=1
ORBIIOPIPv6=0

The /etc orbitrc on server contains:

ORBIIOPUSock=0
ORBIIOPIPv4=1
ORBIIOPIPv6=0

My client machine orbit config files are the same

When I shutdown lo interface my client and server will not communicate on the 
same machine. How do I tell orbit to use eth0 so my client and server can 
work on separate different machines? 

Thanks,
