Rogue Detect sends DHCPDISCOVER packets to the network and listens for DHCP servers to respond. It can run continuously as a daemon, or do a single probe and quit. Its written in Perl and can be easily extended to take any action you can think of in response to an unknown DHCP server (send... Platforms: *nix

Hogwash Light BR is an Intrusion Prevention System that can filter packets directly in the layer 2 of the OSI model (so the machine doesnt need even an IP address). Detection of malicious/anomalous traffic is done by rules based in signatures, and the user can add more rules. It is an efficient... Platforms: *nix

Useful Traffic Accounting Dragon is a traffic accounter that actually gives useful information about traffic instead of stupidly counting incoming/outgoing packets. Dragon accounts traffic by user, program and timestamp and puts this information into useful correlation. Dragon is implemented... Platforms: *nix

Sniffit is a packet sniffer for TCP, UDP and ICMP packets. sniffit is able to give you very detailed technical info on these packets (SEQ, ACK, TTL, Window etc.) but also packet contents in different formats (hex or plain text). Sniffit was actually the start of my TCP/IP experimental phase. As... Platforms: *nix

In an effort to be able to play Halo 2 with some out of state friends, I wrote an xbox system link proxy that would essentially bridge only xbox network traffic across across layer 3 networks using UDP. Written in C and uses libpcap and libnet. A later update added multicast support so Apples... Platforms: *nix

libpal allows you to create your own forged IP, TCP, and ICMP packets. libpal project is straightforward to use and is a powerful tool for building artificial TCP/IP packets. At the time of this writing the only supported platform is LiNUX/i386, but things will develop, so give us some time and... Platforms: *nix

Arphound project is a tools that listens to all traffic on an ethernet network interface, and reports IP/MAC address pair, as well as events such as IP changes, IP conflict, IP addresses with no RDNS, various ARP spoofing, and packets not using the expected gateway.
