Hi, I have a client server application, and want to tunnel it in this way: a script select a free port in a random way, write the stunnel.conf file. with "accept=<the_found_port>" and "connect=<my_server>" and run my client application passing to 127.0.0.1:<the_found_port> as server address. The problem is that i need to be sure that no other client or user can access <the_found_port> while the application is running. I guess that it should be possible to do it, but i wasn't able to.

Can anybody help me?

Thanks
