Info about ruptime, rwho, and rwhod
======================================================
usage: ruptime [-alrut]

If no options are specified, the listing is sorted by host name.
Options change sorting order as follows:

   -a  Show all users, not just active ones
   -l  Sort by load average.
   -r  Reverse the sort order.
   -t  Sort by up time.
   -u  Sort by the number of users.
======================================================
usage: rwho [-a]

  -a means: all users, not just active ones
======================================================

Usage:   rwhod  [options]

Options:
   (Only the uppercase part is needed;
   the '-' may be omitted for all options;
   all options may be entered in upper/lower/mixed case;
   all options may be preceded by 'NO' to turn them off (e.g.: -nopoint)

  -All        Check for both broadcast and point-to-point
              interfaces (default)

  -AL_INTERVAL #   Sets main loop sleep time to # seconds.
              Note: other rwhod/rwho/ruptime processes may
              think this system is dead if interval is much
              more than 180 seconds.
              Default: -AL_INTERVAL 180
  -AUTO       Automatically determine a broadcast IP Address
              by using the upper 24 bits of the address from
              the first incoming rwhod message received.
              This is needed on MPE/iX, where inaddr_broadcast
              seems to be broken.
              Default: -ALL

  -Broadcast  Check for Broadcast interfaces (e.g., ethernet)
              during configuration.
              Note: this does not appear to work.

  -Debug1     Enable some debug output.

  -DEBUG2     Enable some more debug output.

  -DEBUG_SENDTO   Enable verbose debug output for each sendto

  -DEBUG_UT   Enable verbose debug output each 'loop',
              displaying the user information we obtained.

  -Help       Display this information.

  -INADDR_broadcast   Attempt to broadcast rwhod information
              on the local network by using an IP address
              of INADDR_BROADCAST (which is 255.255.255.255).
              Note that this works on HP-UX and Linux, but
              apparently not on MPE/iX.

  -Point      Check for point-to-point interfaces
              during configuration.
              Note: this does not appear to work.

  -REPORT     Display the various flags in rwhod after
              parsing the options line.

  -Self       Send a copy of the rwhod info to 127.0.0.1
              This is useful on MPE/iX, because the
              local broadcast (x.y.z.255) doesn't seem
              to send a copy to *our own machine*!

  -Version    Displays version

Typical MPE/iX usage:  rwhod -s

NOTE: you may want to build an /etc/mpe_usermap file!
Syntax:
   build /etc/mpe_usermap; rec=-62,16,f,ascii;ksamxl;key=(b,1,24; b,31,32,dup)
and check out the prototype one (/etc/mpe_usermap.example).

Edit the example as you like, then:
   :file example = /etc/mpe_usermap.example
   :file real    = /etc/mpe_usermap
   :fcopy from=*example; to = *real
