toolkit, and continues to be developed there. Typical applications of Mausezahn include: * Testing or stressing IP multicast networks * Penetration testing of firewalls and IDS * Finding weaknesses in network software or appliances * Creation of malformed packets to verify whether a system processes a given protocol correctly * Didactical demonstrations as lab utility Mausezahn allows sending an arbitrary sequence of bytes directly out of the network interface card. An integrated packet builder provides a simple command line interface for more complicated packets. Since version 0.38, Mausezahn offers a multi-threaded mode with Cisco-style command line interface.

Features

As of version 0.38 Mausezahn supports the following features: *
