(Only about 2.4 from two other machines, one of them only ~15 ms away, though.) It's very nice that latency is about the same over both IPv4 and IPv6. (Those tests were from tick.mattnordhoff.com, which uses an HE tunnel, FWIW.) > If IPv6 works well enough: how to make this known to the pool? Just add the IP, same as anything else. (Last I tried, adding a hostname didn't work; apparently it doesn't look up AAAA records.) Currently, the pool doesn't actually support IPv6 NTP servers, so, though you can add it, it won't be distributed, and the monitoring and statistics won't work either. > Udo -- Matt Nordhoff _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
