Carnivore

Carnivore is a surveillance tool for data networks. At the heart of the project is CarnivorePE, a software application that listens to all Internet traffic (email, web surfing, etc.) on a specific local network. Next, CarnivorePE serves this data stream over the net to an unlimited number of creative interfaces called "clients." The clients are each designed to animate, diagnose, or interpret the network traffic in various ways.
