IPv6 Addressess


I have static networking for IPv4 setup as follows on Ubuntu 10.04 LTS and all is working well.

auto lo

iface lo inet loopback

auto eth0 eth0:0

iface eth0 inet static


netmask gateway
iface eth0:0 inet static address
netmask gateway
For IPv6 I added the following: iface eth0 inet6 static address netmask 64 gateway fe80::1 up ip -f inet6 addr add /64 dev eth0 up ip -f inet6 addr add /64 dev eth0 up ip -f inet6 addr add /64 dev eth0 On reboot this works fine and when I do a networking restart it works for a little while and then I start getting this: * Reconfiguring network interfaces… SIOCADDRT: File exists Failed to bring up eth0. ssh stop/waiting ssh start/running, process 13580 All the IPv4 addresses are up on eth0 and the virtual interface and the main IPv6 address also comes up on eth0 but the three addresses for the IPv6 range don't. This appears random. Any thoughts?
