Linux – how to completely disable ipv6 on Ubuntu 9.04

ipv6linuxnetworkingUbuntu

what i have done:

/etc/modprobe.d/blacklist.conf

blacklist net-pf-10
blacklist ipv6

/boot/grub/menu.lst

title           Ubuntu 9.04, kernel 2.6.28-15-server
kernel          /boot/vmlinuz-2.6.28-15-server ... ro quiet splash ipv6.disable=1
initrd          /boot/initrd.img-2.6.28-15-server
quiet

But still:

root@bubi:~# ip a | grep inet6
    inet6 ::1/128 scope host
    inet6 fe80::a00:27ff:fecf:c12e/64 scope link
root@bubi:~#

Any idea?

I've read much about that, and it seems to be a bug in 9.04 distribution. You'll have to recompile the kernel without ipv6 in order to do it.

My case was that Opera does not work with ipv6 turned on.
