Use lftp for Linux command line FTP with explicit TLS/SSL. I was still having trouble though with lftp and implicit TLS/SSL. Below is the command to use lftp to connect to an FTP server that requires an explicit TLS/SSL.
lftp -du user,password ftp.example.com
You should see the below after connecting. Type ls to see if you get a directory listing and everything has worked.
lftp email@example.com:~> ls
Thats pretty much it. I will post in the future about lftp and implicit TLS/SSL connections.
