So after installing and booting FC2-test1, I see that the ipv6 module is loaded, and in use so I can't unload it. Running `ip link` shows an interface sit0, which I believe is an ipv4/ipv6 tunnel. Running `netstat -lntp` shows sshd bound to :::22. So What I think is happening, is sshd is default configured to bind to the ipv6 IPADDR_ANY and the sit0 interface is there so ipv4 machines can connect to it. This seems awfully stupid to me. I don't have an ipv6 address, I don't want an ipv6 interface, and I don't want to add the extra step of mapping from ipv4 to ipv6 for sshd 'just because it can.' Can anyone comment on my assumptions, and if they are right, how to get sshd on plain ipv4 0.0.0.0:22 and get rid of ipv6/sit0.
