    Try looking at beej's guide to network programming to give you the basics of network programming. Then look in the rfc doc given by rajaamirapu(above) to see what FTP commands and response codes there are. The rest depends on what you want to do!

    the basic framwork

    in the main loop :
    (1) wait for connection (accept())
    (2) create a thread to handle this connection, and then go back to (1) to accept next connection

    thread for handling a connection :
    (1) send() - send welcome string
    (2) a loop
        (a) recv() - receive client command
        (b) send() - send response
        (c) optionally, do something else (e.g. open a data connection
        (d) execute loop as long as timeout doesn't pass, or client sends QUIT command
    (3) close connection, and terminate thread
