Network Scanner

Simple python script which uses pcap, arp-scan, and avahi to:

1. Find hosts that are on the LAN passively
2. Uses an arp-ping to actively identify hosts
3. Scan each host to determine open ports and services
4. Store record of hosts in JSON file, html webpage, or prints to screen

Note: Since IP addresses can change, the hosts are finger printed via their MAC address.

Alternatives

Fing is a great and fast network scanner, I have their app on my iPad. However, when using the fing commandline tool for RPi I have noticed that there are errors in the MAC address and therefore don't trust it for this application.
