Goal

From a PC on our network, we want to view a web page served up by any node on our wireless IP network. This will allow us to look at sensor values or other data stored there.

Building

We'll put the rpl-border-router (with no webserver) on the node connected to the PC, and talk SLIP over USB between it and the PC. The other node will run webserver-ipv6 with 'webserver-nano'.

$ cd examples/ipv6/rpl-border-router
$ make TARGET=avr-zigduino savetarget
$ make upload WITH_WEBSERVER=0 WITH_SLIP=1 AVRDUDE_PORT=/dev/ttyUSB0 -j10
$ cd examples/webserver-ipv6
$ make TARGET=avr-zigduino savetarget
$ make WITH_WEBSERVER=webserver-nano -j10
$ make upload login WITH_WEBSERVER=webserver-nano AVRDUDE_PORT=/dev/ttyUSB1

Running

This has to be done in another window, because "make login" above took over that window. Here we will bring up the tunnel, and try everything out, one thing at a time. Ping the router, ping the webserver, do the 'get'.

$ sudo ../../../tools/tunslip6 aaaa::1/64 -s /dev/ttyUSB0 -B 38400 -v6
$ sudo route -A inet6 add fdfd::/64 dev tun0
$ ping6 fdfd::3
$ ping6 fdfd::1
$ curl -g "http://[aaaa::11:22ff:fe33:4401]/"

Here's what success looks like!

$ curl -g "http://[aaaa::11:22ff:fe33:4401]/"
