Directory examples/contiki now contains a small example server for Contiki and a Makefile for platform minimal-net. Build: make contiki # clones Contiki make server # creates the minimal-net coap server Run: Unfortunately, you have to run the server with sudo unless you set CAP_NET_ADMIN for both, the server executable, and ifconfig (sudo setcap cap_net_admin+pei ...). sudo ./server Then, add the server's interface address to the tap0 device and optionally set a default route: sudo ip -6 a a aaaa::1000 dev tap0 sudo ip -6 r a aaaa::/64 dev tap0 Although everything should work now, it does not. I had to send router advertisements on tap0: sudo radvd -C ./radvd.conf Note that on Debian (and Ubuntu, and ...), radvd will not start when IPv6 forwarding is disabled (which is usually the case on end systems). Trying to enable like this did not work for me: sudo sysctl -w net.ipv6.conf.tap0.forwarding=1 sudo sysctl -w net.ipv6.conf.tap0.mc_forwarding=1 Workaround (ugly): get the radvd sources, compile them and use that.
