Introduction - If you have any usage issues, please Google them yourself
Mausezahn is a free fast traffic generator written in C which allows you to send nearly every possible and impossible packet. It is mainly used to test VoIP or multicast networks but also for security audits to check whether your systems are hardened enough for specific attacks.
Mausezahn can be used for example:
As traffic generator (e. g. to stress multicast networks)
To precisely measure jitter (delay variations) between two hosts (e. g. for VoIP-SLA verification)
As didactical tool during a datacom lecture or for lab exercises
For penetration testing of firewalls and IDS
For DoS attacks on networks (for audit purposes of course)
To find bugs in network software or appliances
For reconnaissance attacks using ping sweeps and port scans
To test network behaviour under strange circumstances (stress test, malformed packets, ...)
