Netcat 1.10 is an updated release of Netcat, a simple Unix utility which
reads and writes data across network connections using TCP or UDP 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.

Some of netcat's major features are:

   * Outbound or inbound connections, TCP or UDP, to or from any ports
   * Full DNS forward/reverse checking, with appropriate warnings
   * Ability to use any local source port
   * Ability to use any locally-configured network source address
   * Built-in port-scanning capabilities, with randomizer
   * Built-in loose source-routing capability
   * Can read command line arguments from standard input
   * Slow-send mode, one line every N seconds
   * Hex dump of transmitted and received data
   * Optional ability to let another program service established
     connections
   * Optional telnet-options responder

A very short list of potential uses:

   * Script backends
   * Scanning ports and inventorying services, automated probes
   * Backup handlers
   * File transfers
   * Server testing, simulation, debugging, and hijacking
   * Firewall testing
   * Proxy gatewaying
   * Network performance testing
   * Address spoofing tests
   * Protecting X servers
   * 1001 other uses you'll likely come up with

Changes between the 1.00 release and this release are fairly minimal:

   * Better portability -- updated generic.h and Makefile [thanx folks!]
   * Indication of local-end interface address on inbound connections
   * That's *Dave* Borman's telnet, not Paul Borman...
   * Better indication of DNS errors
   * Total byte counts printed if -v -v is used
   * A bunch of front-end driver companion programs and scripts
   * Better handling of stdin arguments-plus-data
   * Hex-dump feature
   * Telnet responder
   * Program exec works inbound or outbound now
