Pipss project is an Internet protocol scanner/sniffer in 3D.
Perl Internet Protocol Scanner/Sniffer (pipss) is a small series of tools for creating a 3-dimensional network monitoring system.
Packets fly through the air from IPs to a given firewall/gateway. Pipss uses Tethereal to gather info, then uses OpenGL to create the scene.
Traffic is updated in real time (about every 30 seconds) and is even color coded.
This program should primarily be used by network admins with a decent amount of traffic to cover, otherwise it's not really interesting.
