Depends on what you're trying to do. Most programming environments have
a way to create a socket on an available port number.
For example (from JavaDoc for java.net.ServerSocket):
public ServerSocket(int port)
throws IOException
Creates a server socket, bound to the specified port. A port of 0
creates a socket on any free port.

Hi,
Is there a task or script that can be used to generate a (random) port
number that is known to be available? I'm trying to setup some server
instances for testing purposes, and I'd prefer not to hard-code port
numbers.
I'm running on Windows, so I don't have awk/sed available by default,
either.
