MAC address of remote linux machine

[aravindm]

Hi,

I am trying to find the MAC address of a remote linux machine that is not present in my LAN. Is there any tool that I can use to find it. I read in one of the posts that GetMAC can be used. Let me know how to achieve this.

The easiest way would be log in and run ifconfig to show the MAC. If you can't login to the system you would need access to the switch/subnet it's connected to. If you can't get that, I'd suggest revisiting why you want the MAC address.

ping the machine, and then dump your arp cache with "arp".

eg

simon@lappy:~$ ping BelkinPrintServer.scottlan
