Stu 2010-02-17 Packet has been pulled from public distribution and is currently under development with no slated release date. I'll be happy to provide a dev snapshot if anyone wants.

[ Explain what network packets are, and UDP and TCP (and others?), and how several other extensions, as well as the built-in socket, all have capabilities. ]

[ ... tclpcap, pktsrc, hping3, ... socket, ... TCP, UDP, ... ]

HexInject is a versatile packet injector and sniffer, that provides a command-line framework for raw network access. It includes a packet forger, written in Tcl, which uses a simple packet representation format based on hping3's packet description format.

A command-line UDP packet reflector/forwarder with optional Tcl/Tk interface: [L3 ].

This application operates in two modes:

  • packet reflector that sends UDP packets back to the host that sent them.
  • packet forwarder that forwards packets between a number of unicast UDP sources acting as bridge when multicast is not available.

The reflector will also drop packets, duplicate packets, and add jitter on a per port basis. The default method of setting parameters is through a Tcl/Tk user interface, but they can also be sent to the application via TCP so they can be set by TELNET or alternate interfaces.
