The Nemesis Project is designed to be a command line based, portable human IP stack for UNIX-like and Windows sytems. 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, UDP protocol support + Layer 2 or Layer 3 injection (by presence/absence of -d switch) on UNIX-like systems. + Layer 2 injection on Windows systems (regardless of whether -d is used. + 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 explaning its functionality.
