nemesis

The Nemesis Project is designed to be a command line based, portable human IP stack for UNIX-like and Windows systems. The suite is broken down by protocol, and should allow for useful scripting of injected packets from simple shell scripts. Key Features ARP/RARP, DNS, ETHERNET, ICMP, IGMP, IP, OSPF, RIP, TCP and UDP protocol support Layer 2 or Layer 3 injection on UNIX-like systems Layer 2 injection (only) on Windows systems Packet payload from file IP and TCP options from file Tested on OpenBSD, Linux, Solaris, Mac OS X and Windows 2000 Each supported protocol uses its own protocol injector which is accompanied by a man page explaining its functionality. Consult the ChangeLog for release details, and the documentation for each protocol injector for in-depth descriptions of the available functionality. Examples Inject malformed ICMP redirec DHCP Discover (must use sudo and to send with source IP 0.0.0.0): IGMP v2 join for group 239.186.39.5 IGMP v2 query, max resp. time 10 sec, with Router Alert IP option IGMP v3 query, with Router Alert IP option Random TCP packet DoS and DDoS testing
