FTP over SSL/TLS (implicit encryption)
 

How to connect from Linux server to FTP server over SSL/TLS(implicit encryption)?

There is no standard way to do what you're trying to do. You'd have to have custom software at both ends to act as an FTP server/client and to handle the encryption/decryption.

A better idea would be to run an SSH server at the server end, and then use sftp to connect to it, which will allow you to transfer files through the encrypted tunnel. This is a much more standard method.
