Netcat is a featured networking utility which reads and writes data across
network connections, using the TCP/IP protocol.<br>
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.<br>
<br>
It provides access to the following main features:
<ul>
  <li>Outbound and inbound connections, TCP or UDP, to or from any ports.
  <li>Featured <b>tunneling mode</b> 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.
  <li>Built-in port-scanning capabilities, with randomizer.
  <li>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.
  <li>Optional RFC854 telnet codes parser and responder.
</ul>

Although the project development is marked as beta, GNU Netcat is already enough
stable for everyday use.<br>
Goals of this project are <b>full compatibility</b> with the original nc 1.10 that
is widely used, and <b>portability</b>. GNU Netcat should compile and work without
changes on the following hosts:

<ul>
  <li>Linux (test host: alphaev67-unknown-linux-gnu)<br>
  <li>FreeBSD (test host: i386-unknown-freebsd4.9)<br>
  <li>NetBSD (test host: i386-unknown-netbsdelf1.6.1)<br>
  <li>SunOS/Solaris (test host: sparc-sun-solaris2.9)<br>
  <li>MacOS X (test host: powerpc-apple-darwin6.8)<br>
</ul>

Other operating systems could be supported with minor source modifications, since
the code has been written following the GNU coding standard conventions.<br>
If you find a bug or you want to report a successfull build on another OS, use the
<a href="http://sourceforge.net/tracker/?atid=466046&amp;group_id=52204&amp;func=browse">bug
tracking system</a>.<br><br>

Soon the project will split releases between &quot;stable&quot; releases and &quot;development&quot; releases to
improve development speed and the introduction of new features without requiring too much testing.<br>
<br>
For further information, see the README and ChangeLog files in the package.
<br>
If you are courageous enough to try the newest development version or you
want to contribute patches, you may want to check out the version in the
<a href="download.php#cvs">CVS repository</a>.<br>
