Penetration Testing: Pinging a MAC address

[Alex Balayan <alex.balayan () Nettasking com>]

Hi all, 


Say you are conducting a internal pen-test and you are only given a network
port to plug your laptop into. Say you have obtained a list of MAC addresses
that are on that ethernet segment. Is there a tool on *nix that can be used
to ping a MAC address (00:20:A4:F7:89:15) to see if you get a reply back
from that device?

Thanks in advance.
