This example features a simple webserver running on top of the IPv6 contiki
|
|
|
|
|
stack.
|
|
|
|
|
|
|
|
|
|
For this example to run properly the UIP_CONF_TCP compilation flag must be set
|
|
|
|
|
to 1 in the contiki-conf.h file of the platform.
|
|
|
|
|
|
|
|
|
|
By default contiki ipv6 nodes are configured with the low-power RPL protocol
|
|
|
|
|
and direct outgoing packets through the RPL parent to a mesh border router.
|
|
|
|
|
Access to the webserver thus requires at least one other node to as the RPL
|
|
|
|
|
root. The Makefile changes the default to no RPL for the minimal-net target.
|
|
|
|
|
Override the RPL choice with
|
|
|
|
|
|
|
|
|
|
make TARGET=minimal-net UIP_CONF_RPL=1
|
|
|
|
|
make TARGET=any-other UIP_CONF_RPL=0
|
|
|
|
|
|
|
|
|
|
The RPL mesh border router can be configured with this webserver using the
|
|
|
|
|
/examples/ipv6/rpl-border-router/ example.
|
|
|
|
|
|
|
|
|
|
If you are using the minimal-net platform without RPL you can access the
|
|
|
|
|
webserver through the link local address by appending the interface descriptor
|
|
|
|
|
shown at launch, e.g.
|
|
|
|
|
|
|
|
|
|
wget http://[fe80::296:98ff:fe00:0232%tap0] (linux)
|
|
|
|
|
ping http://[fe80::206:98ff:fe00:0202%nnnn] (Windows)
|
|
|
|
|
|
|
|
|
|
The lower 64 bits are derived from the ethernet EUI-48 "mac address" in uip6.c:
|
|
|
|
|
|
|
|
|
|
uip_lladdr_t uip_lladdr = {{0x00,0x06,0x98,0x00,0x02,0x32}};
|
|
|
|
|
|
|
|
|
|
The ipv6 prefix can be hard-coded in the build or assigned through a
|
|
|
|
|
host router advertisement. If hard-coded just assign the prefix to the
|
|
|
|
|
interface:
|
|
|
|
|
|
|
|
|
|
sudo ip -6 address add fdfd::1/64 dev tap0 (linux)
|
|
|
|
|
netsh commands or the interface GUI (Windows)
|
|
|
|
|
|
|
|
|
|
On linux you can set up router advertisements as follows:
|
|
|
|
|
|
|
|
|
|
ifconfig tap0 inet6 3ffe:0501:ffff:0100:0206:98ff:fe00:0231
|
|
|
|
|
ip -6 address add 3ffe:0501:ffff:0100:0206:98ff:fe00:0231 dev tap0
|
|
|
|
|
|
|
|
|
|
- You might need to add a route:
|
|
|
|
|
|
2015-09-30 16:06:58 +02:00
|
|
|
ip -6 route add fd00:0000:0000:0000:0206:98ff:fe00:0232/64 dev tap0
|
2013-03-26 13:09:49 +01:00
|
|
|
|
|
|
|
|
- Then configure a global address by sending a router advertisement (RA) with a
|
|
|
|
|
prefix option. You can use radvd for example to generate such a packet.
|
|
|
|
|
Note: You should set the preferred and valid lifetime to reasonable value to
|
|
|
|
|
avoid clock wrap-around. E.g.:
|
|
|
|
|
|
|
|
|
|
AdvPreferredLifetime 400;
|
|
|
|
|
AdvValidLifetime 600;
|
|
|
|
|
|
|
|
|
|
Assume the prefix in the RA is: 3ffe:0501:ffff:0100:0000:0000:0000:0000/64.
|
|
|
|
|
and that the resulting address created by the contiki stack is:
|
|
|
|
|
3ffe:0501:ffff:0100:0206:98ff:fe00:0232
|
|
|
|
|
- Finally you can use:
|
|
|
|
|
|
|
|
|
|
wget http://[3ffe:0501:ffff:0100:0206:98ff:fe00:0232]
|
|
|
|
|
|
|
|
|
|
The default webserver and content is in /apps/webserver/...
|
|
|
|
|
Change that using e.g.
|
|
|
|
|
|
|
|
|
|
make clean
|
|
|
|
|
make WITH_WEBSERVER=webserver-nano
|
|
|
|
|
make TARGET=redbee-econotag WITH_WEBSERVER=webserver-nano
|
|
|
|
|
make TARGET=avr-raven WITH_WEBSERVER=raven-webserver
|
|
|
|
|
|
|
|
|
|
*Beware: Make clean before switching make options!*
