IPv6 teredo
Install the miredo package:
$ sudo apt-get install miredo
Remove miredo system startup links:
$ sudo update-rc.d -f miredo remove
Usage:
$ sudo /etc/init.d/miredo {start|stop|restart|reload|force-reload}
IPv6 connectivity tests If miredo is running you should have another interface called "teredo". You can display it with the following command:
$ ifconfig teredo
To test if you can reach the IPv6 network, try the following:
$ ping6 -c 4 www.ipv6.org
$ firefox http://www.ipv6.org/
