2. Setting up an NTP server

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.

#----- start of ntp.conf file ---------------------
# @(#)ntp.server        1.4    97/05/05 SMI
#
# /etc/inet/ntp.server
#
# An example file that could be copied over to /etc/inet/ntp.conf

and
# edited; it provides a configuration template for a server that
# listens to an external hardware clock, synchronizes the local

clock,
# and announces itself on the NTP multicast net.
#
# SEE RFC 1305 ON FOLLOWING CLOCK DEVICES:
# This is the external clock device.  The following devices are
