    Can someone give me some direction relative to pure-ftpd-conf, so I can have some non-standard port for my public IP's and still keep port 21 for

    I know the key to doing it is in "this part" of pure-ftpd.conf, however, any pointers for the proper syntax would be appreciated.

    # IP address/port to listen to (default=all IP and port 21).
    # Bind,21

    My goal at this time is to have the external IP's access FTP on some non-standard port (and denying port 21) while still keeping port 21 open to (localhost) to keep Chkservd service monitor happy.

    Say for instance, I want to accept incoming connections on port 589 (or some other number), but still want to listen on standard port 21.

    I haven't ruled out the possibility of adding an additional global FTP listen port number, and denying access to Port 21 to all except for some trusted IPs and via IPTables.

    I am pondering doing this due to some recent DarkMail.Cgi variants that we have had problems with.

    We had changed our ssh listening ports years ago to non-standard port numbers, and that has alleviated a lot of grief ! That tweak was a home run.

    I am a firm believer in non-standard ports to alleviate the largest bulk of random hacking attempts from the outside world.

    Much Appreciated...
