GNU Netcat

Netcat is a featured networking utility which reads and writes
data across network connections, using the TCP/IP protocol.
It is designed to be a reliable "back-end" tool that can be used
directly or easily driven by other programs and scripts. At the
same time, it is a feature-rich network debugging and exploration
tool, since it can create almost any kind of connection you would
need and has several interesting built-in capabilities.
 
It provides access to the following main features: 
  
* Outbound and inbound connections, TCP or UDP, to or from any ports.   
* Featured tunneling mode which allows also special tunneling such
  as UDP to TCP, with the possibility of specifying all network parameters
  (source port/interface, listening port/interface, and the remote host
  allowed to connect to the tunnel.   
* Built-in port-scanning capabilities, with randomizer.   
* Advanced usage options, such as buffered send-mode (one line every N
  seconds), and hexdump (to stderr or to a specified file) of trasmitted
  and received data.   
* Optional RFC0854 telnet codes parser and responder.
