## THIS REPO IS DEPRECATED Source code of mausezahn moved to netsniff-ng repository: https://github.com/netsniff-ng/netsniff-ng What is Mausezahn? ================== 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, ...) ...and more. Mausezahn is basically a versatile packet creation tool on the command line with a simple syntax and context help. It could also be used within (bash-) scripts to perform combination of tests. Currently Mausezahn is only available for Linux platforms. There are no plans for a Windows version and please do NOT PORT Mausezahn to Windows! Quick Introduction ================== ----------------------------------------------------------------------------- NOTE: Since version 0.38 there is also an 'interactive mode' with more and advanced features. Below, only the legacy 'direct mode' is explained. Please consult mops.html in /usr/share/mz/ or https://www.perihel.at/sec/mz/ for more information about this interactive mode. ----------------------------------------------------------------------------- Let me give you a quick example to demonstrate how simple it is to work with Mausezahn. Please note that you must have root rights. ▶ 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" Note that this 'frame' is (by intention) completely invalid with respect to the Ethernet standard; the frame is too short (called a 'runt') and has a broadcast source address. ▶ But 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 10.7.7.42: # mz eth0 -A 10.7.7.42 -B 192.168.1.2 \ -t dns "q=www.thehostyouseek.com, a=172.16.6.66" Of course you can manipulate much more in the DNS header, simply type mz -t dns help for additional help. ▶ Perform a TCP SYN-Flood attack against all hosts in subnet 10.5.5.0/24 which are in VLAN 100. Try out all 1023 well-known ports. Provided that you are in the native VLAN 50 you can reach the target via VLAN-hopping. Repeat the whole attack endlessly by setting the count option to zero: # mz eth0 -c 0 -Q 50,100 -A rand -B 10.5.5.0/25 -t tcp "flags=syn, dp=1-1023" ▶ Confuse the spanning tree: Behave like a root bridge and generate BPDUs with lowest Bridge ID every two seconds: # mz eth0 -c 0 -d 2s -t bpdu As you see you don't even need to specify any other BPDU parameters because Mausezahn assumes that your PC wants to be the root per default. Of course you can modify every BPDU parameter. Event the Cisco-proprietary per-vlan spanning tree PVST+ is supported: # mz eth0 -c 0 -d 2s -t bpdu vlan=314 ▶ Voice over IP connections suffer from jitter (delay variations). Hence it is important to know the jitter across a given path. Using Mausezahn you can precisely measure the jitter continuously. Simply configure a Mausezahn sender and a receiver: TX# mz eth0 -t rtp -B rx.somewhere.net RX# mz eth0 -T rtp "log, path=/tmp" Using these settings, the sender (TX) sends RTP packets every 30 msec to the specified receiver (RX). Station RX stores moving average data in /tmp/rtp_avg_20080801-120233 (filename is current timestamp). The data is a comma seperated list that can be easily analyzed and visualized with standard tools, e. g. R, Matlab, Octave, or this python tool (which needs the matplotlib). Supported Packet Types ====================== For a list of all current supported packet types please enter # mz -t help Disclaimer and License ====================== Mausezahn is basically a network and firewall testing tool. Don't use this tool when you are not aware of its consequences or have only little knowledge aqbout networks and data communication. If you abuse Mausezahn for unauthorized attacks and get caught, or damage something of your own, then this is completely your fault.
