  3. restart the ntpd service:

What is NTP on Linux?

NTP stands for Network Time Protocol. It is used to synchronize the time on your Linux system with a centralized NTP server. A local NTP server on the network can be synchronized with an external timing source to keep all the servers in your organization synchronized with a precise time.

Why is Chrony better than NTP?

14.1.

The things that chronyd can do better than ntpd are: chronyd can work fine when external time references are only intermittently accessible, whereas ntpd needs regular polling of the time reference to work well. chronyd can work well even when the network is congested for longer periods of time.

Where is the NTP configuration file?

conf is a text file with configuration information for the NTP daemon, ntpd. On Unix-like systems, it is commonly found in the / etc / directory, on Windows systems in the C: Program Files (x86) NTPetc or C: Program Files NTPetc directory.

What port does NTP use?

NTP time servers operate within the TCP / IP suite and are based on User Datagram Protocol (UDP) port 123. NTP servers are typically dedicated NTP devices that use a single time reference with which they can synchronize a network. This time reference is usually a Coordinated Universal Time (UTC) source.

What is NTP drift?

The drift file is used to store the frequency offset between the system clock running at its nominal frequency and the frequency required to remain in sync with UTC. If present, the value contained in the drift file is read at system startup and used to correct the clock source.
