Here, the client connects and sends the PASV command, which functions as a request for a port number to connect to. Passive FTP: This is also referred to as passive mode or PASV and it was developed to resolve the issue of servers initiating the connection to the client. In an Active Mode FTP, the client issues a PORT command to the server signaling that it will “actively” provide an IP and port number to open the Data Connection back to the client. In an active mode connection, when the client makes the initial connection and sends PORT, the server will then connect back to the client’s specified data port from its local data port, which is port 20. That is, when a client and server intend to transfer data, they usually start a control connection first in order to negotiate the details of the Data Connection prior to opening it and transferring data. In this mode, the FTP client connects from a random port (n-1023) to the FTP server’s command port (21).
