=7C A program that really wants to use the same socket for both *must*
=7C set ipv6only to 0 via the appropiate setsockopt call.
Either that or:
sysctl -w net.inet6.ip6.v6only=3D0
which it is possible that Joel has in NetBSD 7 but not in NetBSD 6
But Joerg is correct, this has never been the NetBSD default.
I have net.inet6.ip6.v6only = 1 in my system. But I'm sure that I have
not manually set this parameter.
That being said, both squid ans mysql worked fine with -6, -7 and don't
with -8 with default configuration.
I don't know if with -6 and -7 these daemons listen on both IPv4 and
IPv6, but they listen at least on IPv4.
