Public bug reported:
In dconf I have the network-interface configured to lo (loopback). I
use ssh with port forwarding so I don't need or want vino externally
accessible. While port 5900 ends up restricted to localhost, port 5800
is not:
$ netstat -an | grep -i tcp | grep -i listen
tcp 0 0 127.0.0.1:5900 0.0.0.0:* LISTEN
