- | ==== What did I just change? | + | To check that NTP is working, you can perform this command from the SSH terminal: |
- | + | ntpstat | |
+ | You should see something similar to below: | ||
+ | < | ||
+ | synchronised to NTP server (162.159.200.123) at stratum 4 | ||
+ | time correct to within 1050 ms | ||
+ | | ||
+ | </ | ||

+ | \\ | ||
+ | ---- | ||
+ | ==== Under the Hood ==== | ||
+ | In linux (Centos or Alma) there is a file in /etc called ntp.conf, by default, it will list four NTP public sources: | ||
+ | (cat or edit / | ||
+ | In the ntp.conf you will see the following four lines (as long as it has never been edited) | ||
+ | < | ||
+ | # Use public servers from the pool.ntp.org project. | ||
+ | # Please consider joining the pool (http:// | ||
+ | server 0.centos.pool.ntp.org iburst | ||
+ | server 1.centos.pool.ntp.org iburst | ||
+ | server 2.centos.pool.ntp.org iburst | ||
+ | server 3.centos.pool.ntp.org iburst | ||
+ | </ | ||
+ | When you enable NTP from the front panel (virtual or physical) then you will see the IP Addresses that you entered in this file, and there will only be 2 lines of servers. (Because the front panel only allows you to enter two NTP IP addresses). | ||
+ | < | ||
+ | # Use public servers from the pool.ntp.org project. | ||
+ | # Please consider joining the pool (http:// | ||
+ | server 162.159.200.123 iburst | ||
+ | server 51.89.151.183 iburst | ||
+ | </ | ||
+ | \\ | ||
+ | There are two important considerations here: | ||
+ | \\ | ||
+ | 1. You cannot enter DNS names for NTP Servers from the front panel (IP Addresses only) | ||
+ | 2. The front panel cannot show you the NTP Address if you are using DNS Names. | ||
