In Active mode, the Data connection is almost always made on TCP port 20 and is initiated by the FTP server after a Control connection is established. In either mode the Control port is by default TCP port 21. FTP can be configured in either Active or Passive mode. The port used for FTP-Data connection is determined by the mode the FTP server is configured in. The Data phase is used to transfer files. In the Control phase of the connection the client and the server exchange authentication information send and receive FTP commands on TCP port 21.
