C / C++ / MFC

Wikipedia:

In active mode, the FTP client opens a random port (> 1023), sends the FTP server the random port number on which 
it is listening over the control stream and waits for a connection from the FTP server. When the FTP server initiates 
the data connection to the FTP client it binds the source port to port 21 on the FTP server.

In passive mode, the FTP Server opens a random port (> 1023), sends the FTP client the server's IP address to connect
to and the port on which it is listening (a 16 bit value broken into a high and low byte) over the control stream and 
waits for a connection from the FTP client. In this case the FTP client binds the source port of the connection to a 
random port greater than 1023.
