Hi, i have an ipv6 configured on my external if, and with this config:
listen on 10.246.200.1 servers pool.ntp.org sensor * constraints from "https://www.google.com" i get an ipv6 resolution for www.google.com $host www.google.com www.google.com has address 216.58.208.228 www.google.com has IPv6 address 2a00:1450:4007:80e::2004 but no ping for it (dont ask me why): $ping6 www.google.com PING6 www.google.com (2a00:1450:4007:80e::2004): 24 data bytes ^C--- www.google.com ping6 statistics --- 7 packets transmitted, 0 packets received, 100.0% packet loss and ntpd crashes at startup (-current, macppc) ntpd[1932]: listening on 10.246.200.1 ntpd[1932]: ntp engine ready ntpd[1932]: constraint reply from 216.58.208.228: offset -0.413616 ntpd[16978]: fatal: constraint 2a00:1450:4007:80e::2004, signal 15 ntpd[1932]: ntp_dispatch_imsg in ntp engine: pipe closed ntpd[1932]: ntp_dispatch_imsg_dns in ntp engine: pipe closed ntpd[1932]: ntp engine exiting Of course if i disable the constraints, it starts fine. ntpd[4086]: listening on 10.246.200.1 ntpd[4086]: ntp engine ready ntpd[4086]: peer 78.192.65.63 now valid ntpd[4086]: peer 178.33.227.201 now valid ntpd[4086]: peer 176.31.127.215 now valid ntpd[4086]: peer 212.83.131.33 now valid I dunno what ntpd should do in that case, but it shouldnt crash..
