For using pool.ntp.org, this is a better resource:
https://www.ntppool.org/en/use.html https://www.ntppool.org/en/use.html
CentOS/RedHat uses the Chrony NTP agent, and has their own rhel domain within pool.ntp.org.
To only use NTP pool servers within your country, modify /etc/chrony.conf like so:
server 0.us.pool.ntp.org iburst
server 1.us.pool.ntp.org iburst
server 2.us.pool.ntp.org iburst
server 3.us.pool.ntp.org iburst
Hopefully, your country code is also defined as a subdomain.
- bradfa 5y agoYou generally don't need to use the country code. The pool's DNS setup is usually smart enough to give you back servers who are fairly local to you based on your location, assuming your DNS server is fairly local to you. If you're a vendor of a software or device who want to use the NTP Pool, you're asked to get a "vendor zone" which will have your name in the FQDNs used for accessing the pool. The cost to do this is fairly reasonable, much cheaper than running your own NTP infrastructure (I've done it for a former employer).
