NTP Software Installation and Configuration
6
6.7 UNIX Installation
Unix installation must be performed by a user with root
(or super-user) privileges on the system.
The host system is usually configured to start NTP when the system
boots, so that re-synchronization can be established quickly in case of
a power or network failure.
Consult your UNIX system documentation to determine what start-up
scripts must be modified to load NTP at system boot time. Many late
Unix distributions contain administration tools that perform
automatic installation and configuration of startup system tasks such
as NTP.
