Some FTPS servers now support the Clear Command Channel (CCC) command. This tells the FTPS server that immediately after secure login, you'd like the command channel to become unencrypted. This adds more support for firewalled environments. With the command channel in the clear, the firewall can see the response to the PASV command and dynamically open the appropriate ports for the data connection.
