How AI describes Netcat

Netcat (nc) is a compact Unix utility that reads and writes data across TCP or UDP network connections, designed as a reliable back-end tool that can be used directly or driven by other programs and scripts. It can function as both client and server—establishing outbound connections or listening for inbound ones—supporting features like arbitrary ports, DNS checks, source-address options, built-in port scanning, UDP mode, and data hex-dumps. It is intended as a versatile network debugging and exploration tool, capable of transferring data, testing servers, and serving as a template for building custom network applications, with the project hosted on SourceForge.
