Enable NTP service under AIX

1. Configure the/etc/ntp.conf file to add NTP server address information (server 192.168.1.20)
Broadcastclient
Driftfile/etc/ntp.drift
Tracefile/etc/ntp.trace
Server 192.168.1.20

2. Start the XNTPD process

Method 1:# Startsrc-s xntpd0513-059 The XNTPD Subsystem has been started. Subsystem PID is 327788. Method 2:# Smit xntpd Select "Start Using the XNTPD Subsystem"--"BOTH"

3. Check XNTPD Service Status

# Lssrc-ls XNTPD

4. Use Ntpdate to synchronize with NTP server manually
