You already have the code which successfully connected to port 21 on the server, the same code will also work to connect to the IP address and port number that was returned in the PASV response.

BUT

You do not want to make this second connection until it is time to transfer some data. The first connection you established is for commands and responses to commands. The connection you make to the port returned by PASV is for the transfer of data following a command that actually transfers a file, for example RETR or LIST.
