Ncat, which is a reimplementation of the netcat computer networking utility, is a utility which reads and writes data across a network from a command-line interface (CLI), such as a shell prompt or a Microsoft Windows command prompt. It supports TCP and UDP, SSL, and proxy connections via SOCKS4 or the HTTP CONNECT method.
You can downloaded a precompiled binary version of the utility from Nmap.org or this site.
