I know this is a bit of a networking question more than a redhat question, however I'm sure you guys will be able to explain this to me; I'm trying to understand exactly how this works, and have not been able to find any solid authority on the subject; I understand the concept of ports, well know ports, and part of the initial 3 way handshake of a new tcp session; My question is, does the initial receiving host of a session (usually a server) use the port that it's listening for the tcp session, or does it negotiate a port number that is not in use like the client does? For example, host A is a client, host B is a webserver listening on port 80; host A wants some data from host B's port 80; lets say host A wants to use port 6785; will the tcp session then use port 6785 for host A and port 80 for host B, or will they also pick an available port from host B as well; if port 80 is used, how are multiple sessions possible; i.e. how can the host B serve up more web traffic if port 80 is busy?
