It is possible (for whatever reasons) to make your network card broadcast a different MAC address. Suppose your network interface is ethX. Then, to retrieve your MAC address:

$ ifconfig ethX

The thing you want is the 6 byte number in the hexadecimal form, something like this:

HWaddr 00:1D:98:5A:D1:3A

Changing the MAC address is easy, shut down the network interface, change the MAC address and restore the interface. This can be done succinctly, as root:

# /etc/rc.d/network stop
# ifconfig ethX hw ether FF:FF:FF:FF:FF:FF
# /etc/rc.d/network start

where FF:FF:FF:FF:FF:FF is your new MAC address.
