CANalyze is an open source, native CAN interface for Linux that can be built entirely using open source tools. It enables you to monitor and transmit CAN frames using can-utils. Start hacking cars by connecting to the OBD-II port.

1. build or buy a CANalyze
2. $ sudo apt-get install can-utils
3. start hacking

You also need a USB 2.0 type A male to type B male cable and an OBD-II to DB9 cable. Both a CiA DS102-2 or standard OBD-II cable will work. You can find more information about the device in the user guide.
