I have a problem where running ntpdate on my server doesn't return any data therefore I get the following error:
[root@server etc]# ntpdate -d -u -v time.nist.gov

12 Apr 01:10:14 ntpdate[32072]: no server suitable for synchronization found
I have tried Googling the 'no server suitable for synchronization found' error online and I have tried disabling my firewall (running iptables -L returns no rules). I have also confirmed with my DC that there are no rules that are blocking ntp (port 123).
Does anyone have any ideas on how I may fix this?
Btw, this is what the output should look like on a working server in another DC:
