This example features a simple webserver running on top of the IPv6
contiki stack on Zolertia Z1 motes to provide sensor values, and with 
a RPL border router to bridge the sensor network to Internet.


To test the example in COOJA under Linux
----------------------------------------

1. Start COOJA and load the simulation "example-z1-websense.csc"
> make TARGET=cooja example-z1-websense.csc

2. Connect to the COOJA simulation using tunslip6:
> make connect-router-cooja

3. You should now be able to browse to the nodes using your web browser:
   Router: http://[aaaa::0212:7401:0001:0101]/
   Node 2: http://[aaaa::0212:7402:0002:0202]/


To run the example on real nodes under Linux
--------------------------------------------

1. Program the nodes with the websense application
> make TARGET=z1 z1-websense.upload

2. Disconnect the nodes and program one node with the RPL border router
> (cd ../rpl-border-router && make TARGET=z1 border-router.upload)

3. Connect to the border router using tunslip6:
> make connect-router

4. Reboot the router and note the router IP address

5. You should now be able to browse to your router node using your web
   browser: http://[<ROUTER IPv6 ADDRESS>]/. On this page you should
   see a list of all accessible nodes with their IP adresses.
