airport-linkmon

AIRPORT-LINKMON(1)					      General Commands Manual						AIRPORT-LINKMON(1)

NAME

       airport-linkmon	-  Wireless link quality monitor for the original Apple AirPort Base Station ("Graphite") and the Lucent RG-1000 base sta-
       tion

SYNOPSIS

       airport-linkmon

DESCRIPTION

       airport-linkmon allows you to measure the signal strength and noise on the wireless links between your  base  station  and  its	associated
       wireless hosts.

OPTIONS

       airport-linkmon	accepts  no  command-line  options.  airport-linkmon  is  a  wrapper script around the LinkMonitor.jar jar file located in
       /usr/share/java/airport-utils.

       You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG  environ-
       ment variable to 1 to get the debug output from the wrapper script.

ENVIRONMENT VARIABLES

       DEBUG  Set this variable to 1 to get the debug output from the wrapper script.

       JAVACMD
	      The  full  path  to  the	Java  Virtual  Machine	to  use.  By  default,	the  wrapper  uses JAVACMD; if it is not set, it looks for
	      JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can
	      be configured using the Debian alternatives system (see update-alternatives(8)).

       JAVA_HOME
	      The full path where your JDK/JRE is installed.

       JAVA_BINDIR
	      The full path to the directory where the java executable is located.

       JAVA_ARGS
	      Extra command-line arguments to be passed to the Java Virtual Machine.
