Beware to run this on a public or corporate network as using any third party software without the administrator's express permission can lead to you violating the acceptable user policy.

Hope this helps.

How remote?

If its on the same LAN, then you can look the MAC address up in your ARP table.

"arp -a" on windows or linux.

If it isn't in the arp table, ping it first! :)

If it's not on your LAN, however, youcan't find out the MAC address unless you can ask a machine which IS on the same LAN. The mac address is a "local-only" part of the communication process.

The MAC address won't pass through the router so you can't get those beyond your LAN, unless you deploy an agent program at the remote LAN to do the job for you, and report back the result.

You can use the command "arp -a" to look for the MAC address of remote computer within your LAN, as told by ccomley.

rarp is used to lookup the IP address from MAC address.
