Is it possible to free up a comms port?

Posted on 2009-12-21

I have an application that connects to terminals on various ports but one of them does not appear to be be being presented:

TCP    GBCN-IX18V:directplay8  LISTENING   <<<<<<<

I've changed the FQDN to but the rest of the above is what i get from running netstat -a

The application I'm using should be advertising a development environment on port 6073 but I cannot connect at all.  I'm assuming at the moment that that its the appliaction thats not offering the port but could it be simply the server itself thats blocking or refusing to offer the port for connections?  Pretty sure its the appliaction that should offer the connection port yeah?

This is quiet urgent so appreciate all responses!

Thanks and good luck

    What do you mean with 'I have'?
    You developed this or just run it?

    What is the result of the same command if you stop this application?

    What do you mean with 'not being presented'?
    If I assume you're talking of port 6073, it is presented and it is listening.
    It is only a problem that it does not connect, then?

    OK, been away from a keyboard for some time. I understand if no-ones interested in replying :)  I've fixed the above problem but I would appreciate any comment that can clarify how ports are generated on a server.  My thinking is that applications generate "requests" that lead to comms ports being made available by the host server.  Does that make sense?  The program/application is the catalyst in the generation of a particular port. Yeah?  points still up for grabs!
