Geeting Mac Of A Remote Host

[djdrastic]

What is the easiest way of getting a MAC Address of a remote computer ?

I've used arp normally , but I can't seem to get the MAC address , when not in the same LAYER 3 boundary .


Any Replies Appreciated

Nnot possible without logging into the box or switch the machine in question is attached to. MAC's only stay within layer 2 boundries and have nothing to do with IP.

If the remote system was set up for management (i.e., snmp agents loaded), then you could query the remote host for the value of its MAC address, as registered with the MIB.

There is no other way to get the MAC if it exists outside your broadcast domain (VLANs and VPNs would -usually- be the same BC domain).

Good Luck
