ntpdate: no server suitable for synchronization found
Hi,
While doing synchronization activity on clients, I got this error:
Code:
# ntpdate -u 172.42.12.35
27 Feb 04:15:28 ntpdate[11643]: no server suitable for synchronization found.
On server the ntp.conf configuration is as follows:
Quote:
# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
#restrict default kod nomodify notrap nopeer noquery
#restrict -6 default kod nomodify notrap nopeer noquery

# be tightened as well, but to do so would effect some of
# the administrative functions.

#restrict -6 ::1
# Hosts on local network are less restricted.

On client when I execute this command:
Code:
# ntpdate -d 172.42.12.35
I got this message:
