Garmin Wardriver

For my birthday, my wife got me a GPS (Garmin Venture HC).  I have been disappointed in it’s integration with Linux, most particularly it’s ability to communicate with gpsd (usb input, not serial).  I had high hopes of doing some wardriving and kismet does not gather any of the data despite it’s configuration.  I can get gpsd to get some cryptic messages from the device but I found that this command: `gpsbabel -T -t garmin -f /dev/ttyUSB0` will generate the current coordinates.  So instead of getting frustrated, I’ve decided to open my first SourceForge project.  You can find it listed as Garmin Wardriver.

The concept seems simple enough, generate location through direct communication with the GPS device or through the gpsbabel command above and then gather a list of local ESSID’s with their strength.  With this data, updated each second, one could generate a location for entering an ESSID’s area, it’s strength as you move through and when out.  Output this to an overlay for a program such as Google Earth and that is a wardriver!  I can see this branching to more advanced uses but for the basic proof of concept, a command line program should suffice.  This will be written in Python and I’ve looked into utilizing the pygarmin and pywifi modules instead of generating information from preexisting programs.
