- open a port permanently on linux using nc (netcat) [duplicate]
nc is the wrong tool for this job (to a greater or lesser degree based on which version you have; the more appropriate ones have the option to fork a subprocess for each new incoming connection) Use a proper built-to-purpose superserver -- xinetd was the up-and-coming standard 25 years ago; today I'd suggest tcpsvd
