Nemesis 1.4 beta 3 has been released.

---

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, UDP protocol
support
+ Layer 2 or Layer 3 injection (by presence/absence of -d <dev> switch)
  on UNIX-like systems.
+ Layer 2 injection on Windows systems (regardless of whether
  -d <device number> 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 explaining its functionality.

beta3 has been updated to include new features and correct some bugs:

---

Windows support has been improved by updating LibnetNT. A new release (1.0.2g) is available on the Nemesis website.

Full IP fragmentation support using an updated -F command line switch.

TCP SYN flag bug (-fS) corrected.

Support for TCP ECN flags.

Corrected RIP byte ordering in certain header fields.

Corrected ICMP injection bugs.
