Description Andrej Nemec 2016-04-04 08:29:41 UTC

When starting the x11vnc with -localhost specified, it fail to restrict IPv6 accessibility to localhost. This is in conflict with the manual, which states:

-localhost
[...]
IPv6: if IPv6 is supported, this option automatically implies the IPv6 loopback address '::1' as well.
