| + | ===== Ping ===== | ||
| + | We should now be able to ping the border router from the host PC. First, we can ping its auto-configured aaaa::/64 address | ||

| + | |||
| + | ===== Nodes Beyond the Border ===== | ||
| + | |||
| + | We want to reach more nodes than just the one connected. So let's add a route on the host PC. This "route add" command tells Ubuntu that whenever it wants to reach a node whose IP starts with fdfd::/64, it can send that through the tun0 interface. | ||
| + | |||
| + | < | ||
| + | $ sudo route -A inet6 add fdfd::/64 dev tun0 | ||
| + | $ netstat -r6 Kernel IPv6 routing table | ||
| + | Destination | ||
| + | aaaa::/ | ||
| + | fdfd::/ | ||
| + | |||
| + | Now that we have the route set up, we can put another node on the network, and ping that. | ||
| + | |||
| + | Put anything that speaks RPL on fdfd::1, for example rpl-collect/ | ||
| + | |||
| + | < | ||
| + | $ make TARGET=sparrow savetarget | ||
| + | $ make udp-sender.sparrow.u AVRDUDE_PORT=/ | ||
| + | |||
| + | Now see that we can ping it ok: | ||
| + | |||
| + | < | ||
| + | 64 bytes from fdfd::1: icmp_seq=1 ttl=64 time=67.8 ms | ||
| + | 64 bytes from fdfd::1: icmp_seq=2 ttl=64 time=66.3 ms</ | ||
| + | |||
| + | ====== Using the Webserver ====== | ||
| + | |||
| + | 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 ' | ||
| + | |||
| + | < | ||
| + | $ make TARGET=sparrow savetarget | ||
| + | $ make upload WITH_WEBSERVER=0 WITH_SLIP=1 AVRDUDE_PORT=/ | ||
| + | $ cd examples/ | ||
| + | $ make TARGET=sparrow savetarget | ||
| + | $ make WITH_WEBSERVER=webserver-nano -j10 | ||
| + | $ make upload login WITH_WEBSERVER=webserver-nano AVRDUDE_PORT=/ | ||
| + | |||
| + | ===== 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 ' | ||
| + | |||
