aix下開啟ntp服務

1、配置/etc/ntp.conf檔案，添加NTP伺服器位址資訊（server 192.168.1.20）

broadcastclient

driftfile /etc/ntp.drift

tracefile /etc/ntp.trace

server 192.168.1.20

2、啟動xntpd程序

<code>方法1：</code>

<code># startsrc -s xntpd</code>

<code>0513-059 The xntpd Subsystem has been started. Subsystem PID is 327788.</code>

<code>方法2：</code>

<code># smit xntpd</code>

<code>選擇“Start Using the xntpd Subsystem”--“BOTH”</code>

3、檢查xntpd服務狀态

<code># lssrc -ls xntpd</code>

 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:   80 (sec) 

 Clock stability: 0.000000 (sec) 

 Clock frequency: 0.000000 (sec) 

 Peer: 192.168.1.20 

      flags: (configured) 

      stratum:  3, version: 3 

      our mode: client, his mode: server 

Subsystem         Group            PID          Status 

 xntpd            tcpip            172176       active

4、使用ntpdate手動與NTP伺服器同步

<code># ntpdate -d 192.168.1.20</code>

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

transmit(192.168.1.20)

receive(192.168.1.20)

server 192.168.1.20, port 123
