Finding a machine's ethernet address

[mcneill]

I need to be able to find a machine's ethernet address.  I need a command
like:

(1) find_ether somehost
host somehost is 8:0:0:0:0:0

/etc/arp sorta does this but it only prints out machines that are
currently in the arp tables.  I want the ability to get an ethernet
address that is not currently in the arp tables.  

One way would be to force an entry in the arp tables (then I could use
/etc/arp).  But I don't seem to be able to do this reliably.  I've tried
doing a telnet somehost & then an /etc/arp somehost.  This seems to work
on the Ultrix nodes but not on the Sun nodes.

I guess my other option is to make my own version of arp...somehow?
