AIX客户端配置NTP

环境:

OS:AIX 5.3.10

 

AIX客户端配置NTP同步服务器的时间是比较简单的,下面是配置过程.

 

1.编辑/etc/ntp.conf文件添加NTP服务器的地址或域名

broadcastclient
riftfile /etc/ntp.drift
tracefile /etc/ntp.trace
server 0.cn.pool.ntp.org

在最后一行添加红色部分,这个是中国NTP时间池服务器.

 

2.启动xntpd守护进程

#startsrc -s xntpd

或是

#smitty xntpd

选择Start Using the xntpd Subsystem

 

选择BOTH

 

3.查询xntpd状态

[hxl/oracle]$lssrc -ls xntpd
 Program name:    /usr/sbin/xntpd
 Version:         3
 Leap indicator:  11 (Leap indicator is insane.)
 Sys peer:        no peer, system is insane
 Sys stratum:     16
 Sys precision:   -18
 Debug/Tracing:   DISABLED
 Root distance:   0.000000
 Root dispersion: 0.000000
 Reference ID:    no refid, system is insane
 Reference time:  no reftime, system is insane
 Broadcast delay: 0.003906 (sec)
 Auth delay:      0.000122 (sec)
 System flags:    bclient pll monitor filegen 
 System uptime:   63 (sec)
 Clock stability: 0.000000 (sec)
 Clock frequency: 0.000000 (sec)
 Peer: 114.80.81.1
      flags: (configured)
      stratum:  2, version: 3
      our mode: client, his mode: server
Subsystem         Group            PID          Status
 xntpd            tcpip            385112       active

 

4.可以使用ntpdate与服务器做同步

[hxl/oracle]$ntpdate -d 0.cn.pool.ntp.org
