Hi all,
I have a problem with ntpd daemon in my CentOS7 vm. When I try to list peers, command fails:
[root@c7tst ntpstats]# ntpq ntpq> pe ntpq: read: Connection refused ntpq>
By default NTP daemon is stopped in CentOS. Please see NTP daemon is running or not?
Please share the output of "netstat -nupl | grep 123" command for more information.

Hi Ashish,
of course, ntpd daemon is running:
[root@c7tst tmp]$ ps xauw | grep ntp ntp 8238 0.0 0.0 29360 2076 ? Ss 11:09 0:00 /usr/sbin/ntpd -u ntp:ntp -g -4
And:
[root@c7tst tmp]$ sudo ss -putan | grep 123 tcp UNCONN 0 0 172.22.55.1:123 *:* users:(("ntpd",8238,18)) tcp UNCONN 0 0 127.0.0.1:123 *:* users:(("ntpd",8238,17)) tcp UNCONN 0 0 *:123 *:* users:(("ntpd",8238,16))
And /var/log/messages:

But, I am worried about two things. First in /var/log/messages:
Mar 9 11:09:09 c7tst ntpd[8238]: Listen and drop on 0 v4wildcard 0.0.0.0 UDP 123
¿¿????
And second: ss output shows an "UNCONN", that means "unconnected" .... Uhmmm, and I don't understand why .... There is no firewall or blocking gateway between this C7 vm and Internet ...
