The private command can be used to change the switch for TLS security for the data connection.
You can inquire the current setting for this option using the status command.
Data connections are only secured by TLS if the control connection is also secured by TLS. The private command is thus rejected if it is issued when there is a control connection that does not have TLS security.

[ on | off ] |
on
All data connections subsequently established are secured with TLS.
off
Data connections subsequently established are not secured with TLS.
If no argument is specified, the switch changes from on to off or from off to on depending on the initial value.
If no control connection secured by TLS exists, protec on is implemented explicitly ifprivate on is set.
