Disabling ipv6 on Mac OS X 10.3.X

Found out that if you try to "ssh localhost" as to perform troubleshooting you either need to add the ipv6 address for interface lo0 or disable ipv6 altogether. I opted for the larger hammer I initially tried "ifconfig lo0 inet6 down" and the like these commands do nothing for you. After looking in /System/Library/StartupItems for a minute I found "ip6".

ip6 was exactly what I was loooking for, so the magic incantation goes like this:

/usr/sbin/ip6 -d lo0

which will stop ip6 on the interface specified because ip6 -x didn't get me there.
