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

Icmpenum sends ICMP traffic to potential targets on a network. Introduction: Host enumeration is the act of determining the IP address of potential targets on a network. This can be done in both layer 2 and layer 3. Icmpenum sends ICMP traffic for such enumeration. The ICMP packets supported... Platforms: *nix

Xastir ptoject can receive and plot APRS position packets. Development is a collaborative effort of programmers from around the world. Xastir supports many map formats and is highly customizable. Check out the "Screen Shots" link to see just a few of the ways that Xastir can be used. Xastir... Platforms: *nix

mod_iptos can set IPTOS values on outgoing packets to assist traffic shaping. I wanted bandwidth control for a few virtual hosts, but i did not like the userland methods -- they were inaccurate and buggy. I wanted to take advantage of the linux kernel traffic shaping which i was already using... Platforms: *nix

TNV stands for The Network Visualizer or Time-based Network Visualizer and depicts network traffic by visualizing packets and links between local and remote hosts. TNV is intended for network traffic analysis to facilitate learning what constitutes normal activity on a network, investigating... Platforms: *nix

DHCPsql projects implements the RFC2132 and at least RFC3046 as a dynamic configurable SQL-based DHCP server, based on the udhcpd code, extended to mask-and-select by client DHCP packets. Targets: - Discover, start with a working pre prototype, always send first ip in subnet - Leases, SQL... Platforms: *nix

SYNOPSIS use NetPacket::IP; $ip_obj = NetPacket::IP->decode($raw_pkt); $ip_pkt = NetPacket::IP->encode($ip_obj); $ip_data = NetPacket::IP::strip($raw_pkt); NetPacket::IP provides a set of routines for assembling and disassembling packets using IP (Internet Protocol). Methods... Platforms: *nix

Yavipind is a secure tunnel aka 2 peers securely forwarding packets toward each other. It forwards any kind of packet (IPv4, IPv6 or other) sent over the virtual point-to-point device (e.g. tun0). It fully runs in linux userspace. yavipin has been written because i wasnt satisfied by the... Platforms: *nix

diald-top maintains a top-like listing of all packets and their time to live for use with diald. This project needs a new lead developer as the author no longer uses diald. The concept behind diald-top is very simple. I got sick of trying to read a monitor pipe flying by on an extra VC, so I... Platforms: *nix

ippl is a daemon which logs IP packets sent to a computer. It runs in the background, and displays information about the incoming packets. Criteria can be used to specify what packets should be logged and what packets should be ignored. ippl is free software and its licensed under the GPL... Platforms: *nix

modttl modifies the TTL (time to live) of outgoing packets. Platforms: Mac

Libnet is a high-level API (toolkit) allowing the application programmer to construct and inject network packets. It provides a portable and simplified interface for low-level network packet shaping, handling and injection. Libnet hides much of the tedium of packet creation from the application... Platforms: *nix

Packet Flood Generator as the name stands is a projet to produce a threaded traffic generator program, it has support for generating IP, TCP , UDP, ICMP and IGMP packets, also has as feature to keep the connection up. Platforms: *nix

Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more.It can easily handle most classical tasks like scanning, tracerouting, probing, unit... Platforms: Windows, Mac, *nix, C/C++, BSD Solaris

A simple network packet sniffer that dumps all packets to a file. Simple and plain without the overhead of any analyzer. Since it uses libPCAP it supports most expressions you are used from tcpdump. What's new in this version: # fixed "could not find any interfaces bug" # other small bug fixes Platforms: Mac

Covert Channels Evaluation Framework (CCHEF) is a software framework for empirically evaluating covert channels in network protocols running under Linux. Using encryption is not sufficient to secure communication because the simple fact that communication exists is often enough to raise... Platforms: *nix

Data is sent from one computer to another over a network, or from one application to another on a single computer using UDP packets. Requirements: - MATLAB 7.8 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

APSR is a network testing tool, designed to send and receive arbitrary network packets. It can be used to test firewalls, routing, security and many other things. The project is splitted in two main programs, apsend to create packets and aprecv to sniff packets. Features: - Sending and receiving... Platforms: *nix, Perl, BSD

WinTraceRoute is a compact utility that allows you to learn more about the route that the data packets follow from your computer to a destination host. The interface is easy to use, you just have to enter the address and the program will list all the IP addresses. By showing a traversed list of... Platforms: Windows, XP, 2003, Windows Vista, 7, 7x64

Yavipind is a secure tunnel aka 2 peers securely forwarding packets toward each other. It forwards any kind of packet (IPv4, IPv6 or other) sent over the virtual point-to-point device (e.g. tun0). It fully runs in linux userspace. Features:Network efficiency: - small packet overhead: 26bytes... Platforms: *nix, C/C++, BSD
