      loopback interface, is not a point-to-point interface, is

      If a network interface like a bridge or tunnel is required to
452
 
      find a Mandos server, this requires the interface to be up and
453
 
      running before <command>&COMMANDNAME;</command> starts looking
454
 
      for Mandos servers.  This can be accomplished by creating a
455
 
      <quote>network hook</quote> program, and placing it in a special
456

461
 
      with the argument <quote><literal>start</literal></quote> or
