1、配置/etc/ntp.conf文件，添加NTP服务器地址信息(server 192.168.1.20)

broadcastclient

driftfile /etc/ntp.drift

tracefile /etc/ntp.trace

server 192.168.1.20

2、启动xntpd进程方法1：

# startsrc -s xntpd

0513-059 The xntpd Subsystem has been started. Subsystem PID is 327788.

方法2：

# smit xntpd

选择“Start Using the xntpd Subsystem”--“BOTH”

3、检查xntpd服务状态# lssrc -ls xntpd

4、使用ntpdate手动与NTP服务器同步# ntpdate -d 192.168.1.20

17 Nov 10:37:59 ntpdate[131094]: 3.4y

transmit(192.168.1.20)
