It can be used, for example, as a TCP relay (one-shot or daemon), as a daemon-based socksifier, as a shell interface to Unix sockets, as an IP6 relay, for redirecting TCP-oriented programs to a serial line, or to establish a relatively secure environment (su and chroot) for running client or server shell scripts with network connections.

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, including port binding to accept incoming connections. The original Netcat was written by Hobbit in 1995, but it hasn’t been maintained despite its immense popularity. It can sometimes even be hard to find nc110.tgz. The flexibility and usefulness of this tool have prompted people to write numerous other Netcat implementations - often with modern features not found in the original. One of the most interesting is Socat, which extends Netcat to support many other socket types, SSL encryption, SOCKS proxies, and more. It even made this list on its own merits. There is also Chris Gibson’s Ncat, which offers even more features while remaining portable and compact. Other takes on Netcat include OpenBSD’s nc, Cryptcat, Netcat6, PNetcat, SBD, and so-called GNU Netcat.
