TcpCat is a very lightweight open source TCP utility. It takes an IP address and a TCP port as argument, connects to it, and gives the result back to stdout. It was written as a lightweight version of netcat. As such, it works like the Unix cat command, but instead of displaying a file it displays the result from a TCP service.


See the manual page.
