Hello Param,
There are two FTP modes, and your Server is configured to support only PORT
mode.
Both modes initially connect and authenticate on port 21, but from there
PORT will transfer data on port 20 whereas PASV will negotiate a pair of
ports in a high port range for data transfer.
If it doesn't matter to you which mode to use, from your log entries if you
use an FTP client configured for PORT FTP, you won't see any errors.
Also, your FTP client issued a FEAT command. It's a command requesting the
Server identify any optional commands if they exist, so is not a criticial
error if there is no response.
