       rdistd - remote file distribution server program

       rdistd -S [ -D ]

       rdistd -V

       Rdistd is the server program for the rdist command.  It is
       normally run by rdist via rsh(1).

       The -S argument must be specified.  The option is required
       so  that  rdistd is not accidentally started since it nor-
       mally resides somewhere in a normal user's $PATH.

       -D     Enable debugging messages.  Messages are logged via
              syslog(3).

       -V     Print version information and exit.
