sshd + ipv6,
ssh is told to bind only to ipv6
netstat -an shows binding to ::::22
no binding to 0.0.0.0:22
perl script socklist doesnt show anything

ipv4 connections are possible, shown as coming from ::ffff:ip:port

I dont know, is it a bug or a feature,
but I hope that either
1. it will be possible to switch it out either compile or runtime.
2. it will be bug.

otherwise it is not really good to experiment with ipv6 as everything
connected to security must go trough double check now.

elmer.
