- If you are seeing the error message 'May 29 12:58:56 hostname kernel: [ 8274.890176 ] IPv6 addrconf: prefix with wrong length 48' this most likely means you have a badly configured appliance/router on your network. If you are using a linux box as a gateway, you can fix the config for radvd in /etc/radvd.conf and change it to ::64, or remove radvd like I did.
