Well, if you don't have a switch or router between your linux box and
that PC
you are looking for, you can use the following methods.

1. ping ip_addr, then arp will show you MAC-IP pairs that was
discovered.

2. there's a good utility called arpwatch - this is a daemon which
monitors
network activity in your segment and mails you (root at localhost) all
discovered
ip and mac addresses. It also informs you if the mac changes, it is very
useful
if you're sysadmin and try to supervise your network.
