Disable IPv6 on debian wheezy

What I used to do for squeeze ( there is a post about it ) does not seem to work well

The system

# cat /etc/issue /etc/debian_version ;uname -a
Debian GNU/Linux 7 \n \l

7.5
Linux eudoxus 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u1 x86_64 GNU/Linux

Add the following lines to /etc/sysctl.conf

# tail -5 /etc/sysctl.conf 

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1

and
net.ipv6.conf.eth1.disable_ipv6=1 ...
net.ipv6.conf.ifX.disable_ipv6=1
if you have more network interfaces

enable the changes in proc

# sysctl -p
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.eth0.disable_ipv6 = 1

Restart networking

# /etc/init.d/networking restart

even though most of the time I am politically incorrect, this time it seems I got it right :)
