Often referred to as the "swiss army of knife" for TCP/IP networking, Netcat is an extremely versatile Linux utility that allows you to do anything under the sun using TCP/UDP sockets.

In this tutorial, I am sharing a few useful netcat examples, although the sky is the limit when it comes to possible netcat use cases. If you are using netcat regularly, feel free to share your use case.
