I'm a newer to Linux, and I met a problem when using chrony to synchronize the system clock. There is a machine A and it's a ntp server, and I want machine B and machine C to sync time to A. The configuration file in machine B and machine C /etc/chrony.conf is as follows:
server 172.x.x.x # this is ip of ntp server
makestep 1.0 -1 # is this right?
driftfile /var/lib/chrony/drift
local startum 10
allow
and here is my question: After few hours synchronization, the system time of these machines are nearly the same(microseconds different). But when I use the chronyc tracking in machine B, I found the Frequency part shows: 2024 ppm slow while in machine C: 1.024 ppm
Is the frequency ppm of machine B normal?
I tried to make another machine D to synchronize the system clock of ntp server A. And by chronyc tracking, I can see the Frequency: 2.104 ppm slow. So I doubt whether there is some wrong with the machine B (maybe the network delay or the hardware?).
