In short, I need to detect when someone on the network uses my MAC and
my IP address.

Longer story follows. I am on a LAN which might have some potentially
dangerous users. Those users might spoof my MAC address and additionally
use my IP address, thus forcing my box to go offline, and not be able to
communicate with my gateway. What I need is a passive way to check for
something of the sort, and perhaps a notofication into syslog (the
latter is not very important).
