Windows and UNIX network utility.
Quote from the Web site:
- Netcat has been dubbed the network swiss army knife. It is 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. Netcat is now part of the Red Hat Power Tools collection and comes standard on SuSE Linux, Debian Linux, NetBSD and OpenBSD distributions.
Available as <code>nc</code> on many *nix based systems.
Versions for both *nix and Windows are available from @stake (http://www.atstake.com/research/tools/).
There is also socat, which is netcat on steroids.
Security
The encrypted version of Netcat is Cryptcat.
