# Default-Stop: 0 1 6
# Short-Description: start and stop the arpalert daemon
# Description: It listens on a network interface (without using 'promiscuous'
# mode) and catches all conversations of MAC address to IP
# request. It then compares the mac addresses it detected with a
# pre-configured list of authorized MAC addresses.
