The end-users will access this file server via FTP to start copying the files to their local folder/system. FTP requires a TCP/IP network to function, and relies on the use of one or more FTP clients. The FTP client acts as the communication agent to interact with the server to download or upload files. In other words, the FTP client sends out connections to the FTP server. Upon listening to the request from the client to either upload or download a file, the FTP server performs the file transfer operation.
FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a 'data' port and a 'command' port (also known as the control port). Traditionally these are port 21 for the command port and port 20 for the data port. The confusion begins however, when we find that depending on the mode, the data port is not always on port 20.
