Marcy,
How about using qetharp?
samplehost:/tmp # qetharp -n -q eth0
Address HWaddress HWType
Iface
126.24.23.1 01:00:5e:00:4b:4b ether ethr0

Thanks Scott, Philip, and Alan,
That gives me enough info.
Curious though how to map the mac addr to the IP from Linux itself? They
don't show up in arp -n . Would one check at the router?
cdztv17142:~ # netstat -gn (-n being more
needed to avoid the dummy dns names it seems to use).
