Mausezahn
(, German for "mouse tooth") is a fast network traffic generator written in C which allows the user to craft nearly every possible and "impossible" packet. Since version 0.31 Mausezahn is open source in terms of the GPLv2. Herbert Haas, the original developer of Mausezahn, died on 25 June 2011. The project has been incorporated into the netsniff-ng 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.
