Hi,
I am building an examination server.
Will it be a wise idea to let the server choose a random port and listen on it rather than using a fixed port? And if the requirement is such, how would a client know about this random port?
Will using an announcement help?
I would love to change the world but they dont give me the source code!
It's best to have the server use a particular fixed port for listening afaik.
yeah, I too have known that, but someone had just confused me...
Thanks!

True, it better to prefix the port number to avoid confusions later and conflicts.
Just in curious, I had been programming LISP for a while now, and now started to program socket using LISP. With LISP if you don't specify the port number while creating the socket, the LISP interpreter will assign a random port which are available. But how do we do that in C. Do we have a function or something to check for any available port. I know we could use some command like netstat and see what are the port have been used. And perhaps check in the /Dev/port file as well.
And perhaps once we get the port number assigned, we could send a broadcast with port number.
