I still think using ifconfig is feasible. Just do it without the interface 
parameter. That will list all interfaces, their status, bound IP and MAC 
address. We can do a better job of parsing to pick the one bound to the IP 
we are interested in.

However, it is possible for a server to be bound to more than one, so which 
MAC to use in that case? Probably have to try all of them in queries 
against the directory and see which records come back.

The alternative of course is to hard code the OD record name for the server 
in the config and not rely on MAC at all.

I'm not sure what was up with that code - I do have C code that does 
exactly that in Mulberry.
