Public bug reported: Our 10.04 machines have this in /etc/network/interfaces:
auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.87.30.54 netmask 255.255.255.192 gateway 192.87.30.1 iface eth0 inet6 static pre-up echo 0 > /proc/sys/net/ipv6/conf/eth0/autoconf address 2001:610:148:dead::54 netmask 64 gateway 2001:610:148:dead::1 dev eth0 And all would be fine. The pre-up line takes care of disabling autoconf, the address line add a static address. Neither of them work in 12.04 beta2. When the system boots up, the staticly configured address is not there, and instead there are dynamicly configured addresses. Interestingly, /proc/sys/net/ipv6/conf/eth0/autoconf still is 1, despite the "pre-up echo 0 .." line, which indicates something with /proc? This basically prevents me from any furthers testing... It might be a case of RTFM but I couldn't find any.
