ow to disable IPv6 in Linux

http://yourlinuxguy.com/?p=49

So, to disable IPv6 at the kernel level (on most Suse systems, though it’s basically the same on others), do the following:

vi /etc/modprobe.conf

…and change/set the following:

alias net-pf-10 off

Next, …

vi /etc/modprobe.conf.include (or modprobe.conf.local)

…and add the following:

alias ipv6 off

…and reboot to complete the change. That’s all!
