Simple python script which uses pcap, arp-scan, and avahi <http://www.avahi.org>__ 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 <http://www.overlooksoft.com/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.
