NTP Server : Configure NTP Client2023/04/21

 
Configure NTP Client.
 
NTP Client [systemd-timesyncd.service] is running by default on Ubuntu, so it's easy to set NTP Client.
By the way, it's also possible to use Chrony as a NTP Client.
If you use them, simply set only NTP server to sync time, do not set permission to receive time sync requests from other Hosts.
[1] Configure [systemd-timesyncd.service].
