![]() ![]() The endpoint is formed by the protocol specified in the socket() system call and the addressing information specified in the bind() system call. ![]() Server sockets are bound to well-known endpoints where an endpoint is the (protocol, address, port) tuple.If you want a less "in the guts" answer, then: ![]() If you are really interested, then I would advise you to read TCP/IP Illustrated, Volume 2. Even though your server may have a thousand connections with local address 192.168.1.100 port 80, the client combination of address and port will always be different and thus the tuple is always unique. Before accept() passed back the new socket the kernel used these values to create various structures so that in collaboration with the tcp/ip stack all traffic with this tuple will go to the connected socket. The key in understanding how the listening socket continues to listen while the accepted connection is doing its thing is in understanding that tcp connections depend on a 4-tuple of (1) local address (2) local port (3) foreign address (4) foreign port. It is now separate from the original listening socket and is what your server will use to communicate with its peer(s). The important thing to grasp is that in calling accept() the kernel will pass back a new socket. Server sockets call accept() and I think this is the crux of your question because it is a bit mysterious at first. This was explained pretty well in the other answers. If a socket doesn't call bind() the OS will just choose an ephemeral port for it, which is fine for clients because they are doing the calling no one needs to call them. Client sockets can call bind() but almost never do because there is not much point. They want to be associated with a port so that other programs know where to reach them. Server sockets will call bind() to be associated with a port. The difference between the two lies in the system calls each kind of application makes. nfig, Nano sudo nano /home/user/.ivideonserver/videoserverd.At a low level sockets are just sockets regardless of whether they are being used in a server or client application.
