 you will need `netcat` (with IPv6 support). Ubuntu 14.04 comes with netcat IPv6 support pre-installed. On Debian it's available in the
 package `netcat-openbsd`. Be aware that many programs require you to add an option such as -6 to tell them to use IPv6, otherwise they
 will fail. If you're using a _Raspberry Pi_, run `sudo modprobe ipv6` before trying this example, because raspbian does not load the

 On some systems (openSUSE for example), the _firewall_ may interfere, and prevent some packets to arrive at the application (they will
 however show up in Wireshark, which can be confusing). So be sure to adjust your firewall rules, or turn it off (who needs security anyway).

 You should see `testmessage` appear in netcat. Instead of using netcat, you can of course write your own software, but you may have to bind the socket to a specific interface (tap0 in this case). For an example that shows how to do so, see [here](https://gist.github.com/backenklee/dad5e80b764b3b3d0d3e).
