NTP-time synchronization server

The client first installs NTP

 
Yum install ntpshell> ntpdate 95.222.122.210 shell> ntpdate 202.112.10.60 shell> ntpdate 192.93.2.20
 

Note:

When the client Synchronizes time, the following error occurs: No server suitable for synchronization found.

Cause:

After you restart the NTP service on the NTP server, it may take five minutes for the NTP server to synchronize itself or with its server, during this period, when the client runs the ntpdate command,"No server suitable for synchronization found"Error

How do I know that the NTP server has completed the synchronization process with itself?

Run the following command on the NTP server:

 
Shell> ntpq-P
