[root@inth-rac02 ~]# ntpdate 192.168.47.135
29 Nov 23:13:35 ntpdate[8107]: no server suitable for synchronization found
开始以为是防火墙的问题，把防火墙关闭
[root@inth-rac02 ~]# service iptables stop
问题照旧
查看ntp.conf的配置
# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
#restrict default nomodify notrap
# 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 192.168.47.0 mask 255.255.255.0 nomodify notrust notrap
# -- CLIENT NETWORK -------
# Permit systems on this network to synchronize with this
# time service. Do not permit those systems to modify the

# systems as peers for synchronization.
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

结果还是一样
用ntpdate -d提示错误
