Configuring the FTP Client Connection
To launch a secure FTP session, you must configure your FTP client to connect to a listening interface that you have, or will, set up on the SFTP server. A listening interface is comprised of two parts: the IP address of the machine on which the SFTP server runs (that is, the machine on which Connectivity Secure Shell is installed), and an unused port.
Some FTP client applications, let you type the entire listening interface, as ipaddress:port, into the box where you would normally specify the target host’s address. Most FTP applications have a dedicated port parameter, in which case, you can specify them separately. When attempting to make these configuration changes, bear in mind that some FTP client applications may not offer this functionality.
