NTP服务器和客户端的设置及使用(EN版)
accuracy and reliability are modest, clients can be configured to
use broadcast or multicast modes. Where maximum accuracy and
reliability are required, clients and servers operate in either
client, server, or symmetric modes.
[size=2]2. Setting up an NTP server[/size]
1. Copy over /etc/inet/ntp.server to /etc/inet/ntp.conf
# cp /etc/inet/ntp.server /etc/inet/ntp.conf
2. Edit ntp.conf file
I have added lots of comments in this file for clarification.
Default file does not have many comments.
