-r     This option will enable the facility to receive message from the network using an internet domain socket with the syslog service (see services(5)).  The default is to
              not receive any messages from the network.

              This  option  is  introduced in version 1.3 of the sysklogd package.  Please note that the default behavior is the opposite of how older versions behave, so you might
              have to turn this on.
