Client sends the command to server to receive a file through first channel. Now the 2nd channel has to be established to transfer the file from server to client. In normal mode, client starts listening on a port (act as server) and tells the server its ip and the port. Now server connects to client at the specified port and sends file. When there is firewall on client, it might block server to connect to client and that's the reason PASV (passive) mode is required. In passive mode , client tells the server to enter passive mode in response to that server listens on a port and sends the port number to client where client connects to the server at the specified port and receiv...
