I am trying to write a java server that listens on port 50000 (Random selection). The server starts fine, but now I want to test it. Any attempt to telnet to this port is refused (any attempt to telnet to this system is refused).
I first suspected xinetd, but from everything I read about it, it appears as though it will start a service when some attachs to a port. I don't want that - I already have my server started.
Somewhere there is a solution, but I do not have a clue where to begin - is it ipchains , is it /etc/services is it xinetd.
All web pages (many hours of searching) suggest how to close down a system. Nothing about opening one up. Pages on sockect programming all descibe a services that will be started by xinetd.
