12.4.1 Request modes

         There are three different modes which decide how FD treats a
         Request from a remote system.

             1.  Anyone can request. This means that FD will allow any
                 system to Request files from your system, subject to
                 event behaviors and other modifiers.

             2.  Systems in nodelist can request. Similar to (1), but
                 FD will only process Requests received from systems
                 that are listed in your Nodelist database.

             3.  No requests. Forces FD to ignore any received
                 Requests, effectively disabling the ability to
                 request files from your system.
