NTP.CONF
NTP.CONF is the configuration file for the Network Time Protocol Daemon. This file has many
elements however, only a few defaults need to change as underlined in the following sample
file.
# Prohibit general access to this service.
# Enable NTP on this server
restrict default nomodify notrap noquery
# Permit all access over the loopback interface. This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict 127.0.0.1
# -- CLIENT NETWORK -------
# Permit systems on this network to synchronize with this
# time service. Do not permit those systems to modify the
# configuration of this service. Also, do not use those
# systems as peers for synchronization.
# restrict 192.168.1.0 mask 255.255.255.0 notrust nomodify notrap
# --- OUR TIMESERVERS -----
# or remove the default restrict line
# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.

# Undisciplined Local Clock. This is a fake driver intended for
backup
# and when no outside source of synchronized time is available. The
# default stratum is usually 3, but in this case we elect to use
stratum
# 0. Since the server line does not have the prefer keyword, this
driver
# is never used for synchronization, unless no other
# synchronization source is available. In case the local host is
# controlled by some external source, such as an external oscillator
or
# another protocol, the prefer keyword would cause the local host to
