How does an FTP server know the port number to use for a data connection?
What will be an ideal response?
Before making a request to the server, a client allocates a protocol port on its local
operating system and sends the port number to the server. The client binds to the port to await
a connection, and then transmits a PORT command over the control connection to inform the
server about the port number being used.
