here’s a quick script i whipped up a while ago.
\nit uses scapy to perform an ARP ping of a network, and provides a CSV report of any MAC addresses it finds, along with the associated IP’s.<\/p>\n

It requires tcpdump to be installed and in the $PATH, as well as root privs to run.<\/p>\n

#!\/usr\/bin\/env python\n# note that this script requires tcpdump to be installed\n# additionally, it requires root privs to run.\n# ----\n# Portions of this code can be attributed to the book\n# Python for Unix and Linux System Administration\n# by Noah Gift and Jeremy M.
