Let me try again. > For someone who doesn't want to be preached to about the benefits of IPv6, you certainly do a lot of preaching about not wanting IPv6. :) You've been given the tools to do exactly what you want: - comment out IPv6 support in the kernel config file - add WITHOUT_IPV6=yes to /etc/src.conf - rebuild the world and kernel Voila! A version of FreeBSD made especially for you, without any traces of IPv6. Does exactly what you want. Why the long diatribe asking for something else once you've been shown how to do what you want? -- Freddie Cash fjwcash@gmail.com
