It will always try the first address returned by getaddrinfo and doesn't fall back to other addresses if things don't work out. This means if you don't have IPv6 connectivity, but your server does have an AAAA record, then you probably won't be able to talk NTP to the server. The fix is to change ntp.conf to say "server -4 server.name" rather than just "server server.name". (The same problem exists with servers with multiple IPv4 addresses, some of which are unreachable, it's just less obvious...) David.Received on Wed Jul 28 2004 - 12:57:41 UTC
