This simple utility reads and writes data across TCP or UDP network connections. It is designed to be a reliable back-end tool to use directly or easily drive 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 venerable nc relives as ncat and this is a serious update. It retains all of the old functionality and adds several nice features such as group chatting complete with a server. Use this tool when you need to know for sure what a port is communicating back to you.
