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>
Does "ntpq -4 -c peer" work? If so, then the problem is related to access via IPv6 and this line in ntp.conf:
# Permit all access over the loopback interface. This could # be tightened as well, but to do so would effect some of # the administrative functions. restrict 127.0.0.1 #restrict ::1
Uncommnent the IPv6 restrict entry, restart ntpd, and try again.
Yep, using "ntpq -4", works:

Uhmm .. Then, my problem is with Ipv6. I have disabled all IPv6 stack using ipv6_disable=1 in grub.cfg ...
According to this I need to re-enable ... Correct??
