This indeed was a case of RTFM.
However, according to the default /etc/network/interfaces:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
But interfaces(5) does not tell you the whole story.
The part about DNS resolution sits in resolvconf(8).
So in the end my configuration looks like this:
# The loopback network interface
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
# This is an autoconfigured IPv6 interface
iface eth0 inet6 static
autoconf 0
address 2001:610:148:dead::54
gateway 2001:610:148:dead::1
netmask 64
dns-search terena.org
dns-domain terena.org
dns-nameservers 2001:610:1:800a:192:87:106:106
2001:610:188:140:145:100:188:188
And this works as expected, i.e. static addresses and no automatic fluff for my
servers:
root@precise:~# ifconfig
eth0 Link encap:Ethernet HWaddr 00:50:56:86:00:24
inet addr:192.87.30.54 Bcast:192.87.30.63 Mask:255.255.255.192

Title:
Impossible to configure static IPv6 address
Status in “network-manager” package in Ubuntu:
Invalid
Bug description:
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.
Thanks
