I hope this is the right list for this question.
In FreeBSD 8.2, how do I make ntpd not open any
IPv6 ports? I have searched man pages and google,
but haven't found the answer. Some ntpd have the
command line option -4, but that doesn't seem to
be the case with FreeBSD ntpd.
The server runs IPv6, but ntpd will only ever be used
with IPv4 servers, so I don't want any unnecessary
open IPv6 ports for ntpd.
"Use restrict" or "Use a firewall" is not the answer.
I just don't want this junk in netstat -an:
udp6 0 0 fe80:3::1.123 *.*
udp6 0 0 ::1.123 *.*
udp6 0 0 x:x:x:x.123 *.*
udp6 0 0 fe80:2::219:bbff.123 *.*
udp6 0 0 fe80:1::219:bbff.123 *.*
udp6 0 0 *.123 *.*
