Thanks Rick, et. al.

The /sbin/ifconfig eth0 works great!  Now I need to learn a little 
scripting on Linux to pull out the ip address (or install REXX :-).

I have a site that could get the external address but in this case that 
would not help.  We're just tinkering with a way to "find" a  our RH box 
in a morass of Windows  machines.  All the machines in the site go 
through some sort of NAT to get to the real world and thus all share the 
same apparent ip from that point of view.

Kind regards,

Mike
