    NAME
         sonar - display a sonar scope
    
    SYNOPSIS
         sonar   [-ping   hosts-or-subnets]    [-background    color]
         [-sweep-color color] [-low-color color] [-scope-color color]
         [-grid-color  color]  [-text-color  color]  [-ttl   integer]
         [-font   font]  [-ping-timeout  int]  [-team-a-name  string]
         [-team-b-name  string]  [-team-a-count  int]  [-team-b-count
         int] [-debug]
    
    DESCRIPTION
         The sonar program displays a sonar scope on  the  computer's
         screen.   This scope polls a sensor as the sweep goes around
         the scope and displays  what  it  finds  as  bogies  on  the
         screen.   The program is designed to support different modes
         representing different types of sensors.  Currently the only
         implemented  sensors  are  a  simulator,  and a network ping
         function that pings hosts  and  plots  the  results  on  the
         scope.
    
    OPTIONS
         sonar understands the following options:
    
         -background Color
                 The background Color of the screen  not  covered  by
                 the scope.
    
         -sweep-color Color
                 The color of the brightest part of the sweep.
    
         -scope-color Color
                 The color of the circular part of the scope.
    
         -grid-color Color
                 The color to the grid lines overlaying the scope.
    
         -text-color Color
                 The color of the  text  identifying  bogies  on  the
                 scope.
    
         -ttl integer
                 "Time to live": visible time of a Bogie. Try  values
                 between 10 (very short) and 100.
    
         -font font
                 The font used to display text on the scope.  Default
                 "fixed".
    
         -ping-timeout int
                 The amount of time in milliseconds the program  will
                 wait for an answer to a ping.
    
         -ping hosts-or-subnets
                 The list of things to ping, separated by  commas  or
                 spaces. Elements of this list may be:
    
                 simulation  to run in simulation  mode,  instead  of
                             pinging  real hosts (this is the default
                             if the program is not installed setuid);
    
                 hostname    to ping the given host;
    
                 A.B.C.D     to ping the given IP address;
    
                 subnet      to ping the local class  C  subnet  (the
                             nearest 255 addresses);
    
                 subnet/NN   to ping a different-sized local  subnet:
                             e.g.,  subnet/28 would ping a 4-bit sub-
                             net (the nearest 15 addresses);
    
                 A.B.C.D/NN  to ping an arbitrary other  subnet:  the
                             IP  address  specifies the base address,
                             and the part after the slash is how wide
                             the  subnet  is.  Typical values are /24
                             (for 255  addresses)  and  /28  (for  15
                             addresses.)
    
                 filename    to ping the hosts listed  in  the  given
                             file.   This  file  can be in the format
                             used by /etc/hosts, or  it  can  be  any
                             file  that  has  host names as the first
                             element on each line.  If you  use  ssh,
                             try this:
    
                               sonar -ping $HOME/.ssh/known_hosts
    
         -team-a-name string
                 In simulation mode, the name of team A.
    
         -team-b-name string
                 In simulation mode, the name of team B.
    
         -team-a-count int
                 In simulation mode, the number of bogies on team A.
    
         -team-b-count int
                 In simulation mode, the number of bogies on team B.

                 ping  the contents of /etc/hosts if possible, other-
                 wise, will run in simulation-mode.

    NOTES
         In order to use  the  ping  sensor,  this  program  must  be
         installed  as  setuid  root,  so  that it can create an ICMP
         socket.
