ntpq -pn报错localhost: timed out, nothing received的解决办法

 

一. 正常时候：

 

 

二. 故障时候：

故意去掉/etc/ntp.conf的

restrict ::1 行

 

ntpq -pn开始变得卡住。ntpq -4p有结果，ntpq -6p无结果。

 

 

三 . 综上：

/etc/ntp.conf必须要有行

restrict 127.0.0.1
restrict ::1

 

示例：

 

driftfile /var/lib/ntp/drift
pidfile /var/run/ntpd.pid
restrict default nomodify notrap nopeer noquery

restrict -6 deault nomodify notrap nopeer noquery

restrict 127.0.0.1 
restrict ::1

server 2.centos.pool.ntp.org iburst
