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 subnet (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.  Typ-
			   ical 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.

RESOURCES
       Configuration of the targets to ping is best done by setting X Resources.

       background (Color)
	       See option -background, above; default value is black.

       sweepColor (Color)
	       See option -sweep-color, above; default value is #00ff00.

       scopeColor (Color)
	       See option -scope-color, above; default value is #003300.

       gridColor (Color)
	       See option -grid-color, above; default value is #00aa00.

       textColor (Color)
	       See option -text-color, above; default value is #ffff00.

       ttl (integer)
	       See option -ttl, above; default value is 90 or one sweep.

       ping (string)
	       See option -ping, above.  If  set  to  default,	it  will  ping	the  contents  of
	       /etc/hosts if possible, otherwise, will run in simulation-mode.

       font (font)
	       See option -font, above; default value is fixed.

       pingTimeout (Integer)
	       See option -pingtimeout, above; default value is 3000.

       teamAName string
	       See option -team-a-name, above.	Default value is F18.

       teamBName string
	       See option -teamBName, above.  Default value is MIG.

       teamACount int
	       See option -teamACount, above.  Default value is 4.

       teamBCount int
	       See option -teamBCount, above.  Default value is 4.

NOTES
       In order to use the ping sensor, this program must be installed as setuid root, so that it
       can create an ICMP socket.  Root privileges are	disavowed  shortly  after  startup  (just
       after connecting to the X server and reading the resource database) so this is believed to
       be a safe thing to do, but it is usually recommended that you have as few setuid  programs
       around as possible, on general principles.
       chown root.root sonar
       chmod u+s sonar
