To verify the MAC address, bring up an MS-DOS prompt and
ping
a target.
In this example:
ping ??“t 172.16.1.40
The ??“t option instructs the ping utility to ping continuously until stopped.
From the target machine bring up Ethereal (Lab 41) and start a sniffing session.
Catch a few packets and stop the sniffer. From the results, click to highlight one of
the captured, Internet Control Messenger Protocol (ICMP) packets and observe the
center area of Ethereal. From this, the source has a MAC address of
00:0c:29:b6:40:95, which is identical to what the computer with SMAC has identified.
