答复: [chrony-users] the difference about namespace of ipv4 and ipv6

[ Thread Index | Date Index | More chrony.tuxfamily.org/chrony-users Archives ]


There is no other chrony instance running. My question is that when the IPv4 server is mixed with the IPv6 server, the client synchronization status is x. I use the NTP software to verify the same result. Is this the difference? If not, how do you explain that the two IPv4 servers can be synchronized?

The two sources agree to few microseconds. That means that either they use the same clock, or their clocks are synchronized to a common time source. Maybe a forgotten client instance running?
