Ports used by the child socket which was created by server_socket.accept()?

Question

When a server socket creates a child socket, on which port it(child) listens? When I tried to print getLocalPort(), it is always printing the port on which server was listening. When a server socket accepts a connection it creates a new socket, I think. It should listen on a port other than the server socket's port. Otherwise if all the child sockets and server listen at the same port my Multithreaded server should not work. Fortunately it is working.
Can anyone of you please clarify this child-port-number?
Seems that Sun people limited the length of the subject field. Is it?

Answer 1

when you create the socket on your clients you can specify which port the client will communicate from, otherwise it will be randomly generated by the machine:
// CONSTRUCTOR TO USE
Socket(InetAddress address, int port, InetAddress localAddr, int localPort)
just to clear something up, why do you care what the client ports are unless you are CLOSING the connection first, re-opening, and sending data back. once the client connects the stream is open. the only port you need to free up for your firewall is the port the sever socket is listening on so the clients dont get rejected when trying to connect.
i hope this helps.
