If we want all our Linux servers should have the correct time, then we must configure some NTP client which will fetch correct time always from remote NTP Servers and if needed makes the required adjustments for syncing the time. I will use centos-8 to configure NTP Client using external NTP pool, once configured then I will use the same node (centos-8) to configure Chrony as NTP Server while rhel-8 will act as a NTP Client. Check your firewall's documentation to find out how to do that. You may add more directives as provided in the chrony.conf man page. what's the difference between "the killing machine" and "the machine that's killing".
