How to create a socket and leave it in listening mode to receive a connection on an X port of any network IP, either external or internal?
I want to create a script that waits for connections on a given port, and that comes from any netcat-style IP when you run with "-l -p 8080" , for example. So that another file connects to an address on that port (8080 in the case of the example), but that part is not the focus, but create a listener.
I've tried something like socket_create_listen() but it was not successful.
