If we want to make time synchronization for other clients in the LAN, then we should build another relay server, and then point all the client to both servers ( Be careful

calibration target time source is not necessarily accurate. The time skew of different computers in the corporate local area network, especially the time skew between the client/server, can have an impact on some services that require time synchronization. For example, for ease of management, the server has set a time-out period before the account expires and the user cannot access the Internet network. And if your computer time is not synchronized w

1. "The NTP socket is on use, exiting" error appears. The reason for this is that the system NTPD server is running and can be via PS aux | grep ntpd View, if you still want to manually synchronize time, you must first stop the service, the command is:service ntpd stop or/etc/init.d/ntpd stop2.
