    * SUID Root functionality does not work, you will have to run this as
      root, e.g. via `sudo`. Do so at your own risk.
    * This version can be configured interactively when it is run (listen
      interface, etc).
    * You may add the line 'ncsource=en1:name=AirPort' to kismet.conf to avoid
      prompting at startup (assuming en1 is your AirPort card).
