NAME

ntpsetup − Sets up the Network Time Protocol (NTP) service

SYNOPSIS

/usr/sbin/ntpsetup

DESCRIPTION

NTP provides a distributed time synchronization service that distributes time traceable to an accurate time source.  The ntpsetup script configures and runs NTP on your system. You can use ntpsetup to initially set up your NTP configuration or to change your current NTP configuration. 

The ntpsetup script sets up an NTP client or a local NTP server which will use other NTP servers as its time source.  You can not use ntpsetup to set up a local NTP server as a local reference clock. 

Before running ntpsetup, make sure that your system is connected to a local area network, and that the network software is configured and running. Also, use the /usr/bin/ntp command to check that each system that your system specifies as an NTP server is running NTP. 

The ntpsetup script prompts you for the names of the systems that your system will use as NTP servers. If a system that you specify is not in your local /etc/hosts file, you must specify the server’s IP address.  ntpsetup also prompts you for the name of the NTP daemon running on each server (xntpd or ntpd). If you are uncertain which daemon is running on a particular server, choose ntpd.
