I came across this project and I would like to use them as my NTP servers.
Now, this project consists out of 150+ NTP server so it would be list too long to use in my configuration in my opinion.
How would I apply these 4 dynamic hostnames to serve as my NTP servers?
Can't seem to find a wiki on how to do this.
why not using just pool.ntp.org as an NTP server inside the configuration? This address includes all of the other NTP servers, as far as I understand.
simply configure 0...4.<your-country-code>.pool.ntp.org NTP servers and you'll be all set. No need to try and reach all servers 😉
P.S. Before going country specific you'd want to check "You can also use the continental zones (For example europe, north-america, oceania or asia.pool.ntp.org), and a country zone (like ch.pool.ntp.org in Switzerland) - for all these zones, you can again use the 0, 1 or 2 prefixes, like 0.ch.pool.ntp.org. Note, however, that the country zone might not exist for your country, or might contain only one or two timeservers.".
If I configure pool.ntp.org or any of the other NL NTP servers then it directly translates to an IP address.
This means I can go on for about 150 times setting 0--3.pool.ntp.org before having reached all current active NTP servers.
Or am I wrong?
Or would I just configure them 4 once and be set for life?
as https://www.ntppool.org/zone/nl says:
To use this specific pool zone, add the following to your ntp.conf file:
You don't want to try and sync with 150 servers in parallel, right?!!
If you want to use just NL NTP servers, just configure these commands on your Junos device:
set system ntp server 0.nl.pool.ntp.org
set system ntp server 1.nl.pool.ntp.org
set system ntp server 2.nl.pool.ntp.org
set system ntp server 3.nl.pool.ntp.org
You do not have to configure anything more.
