# airport2-ipinspector(1)

WAN monitoring utility for the Apple AirPort Extreme Base Station ("Snow")

## NAME

airport2-ipinspector - WAN monitoring utility for the Apple AirPort Extreme Base Station ("Snow")

## SYNOPSIS

**airport2-ipinspector**

## DESCRIPTION

**airport2-ipinspector** monitors the WAN interface of the base station and sends an email notification whenever the external (WAN) IP address of the base station changes.

## OPTIONS

**airport2-ipinspector** accepts no command-line options. **airport2-ipinspector** is a wrapper script around the *IPInspector.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** environment 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)](/update-alternatives/8.md)).

- **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.
