# check-host-list - Shell script to test arp-scan host list creation
#
# Author: Roy Hills
# Date: 4 February 2011
#
# This script checks that arp-scan creates the host list correctly.
# It uses the undocumented arp-scan option --readpktfromfile to
# read the packets from a pcap file rather than from the network.
#
