# Sample /etc/ntp.conf:  Configuration file for ntpd.

#
# 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
# 10. Since the server line does not have the prefer keyword, this driver
# is never used for synchronization, unless no other 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
# disregard all other synchronization sources, unless the kernel
# modifications are in use and declare an unsynchronized condition.

# NTP server (list one or more) to synchronize with:
#server 0.pool.ntp.org iburst
#server 1.pool.ntp.org iburst
#server 2.pool.ntp.org iburst
#server 3.pool.ntp.org iburst

# Full path of a directory where statistics files should be created
#
statsdir /var/lib/ntp/stats

#
# Location of an alternate log file to be used instead of the default system syslog(3) facility
#
logfile /var/log/ntp

#
# Drift file.  Put this in a directory which the daemon can write to.
# No symbolic links allowed, either, since the daemon updates the file
# by creating a temporary in the same directory and then rename()'ing
# it to the file.

driftfile /var/lib/ntp/drift

# Location of PID file
#
pidfile /var/run/ntpd.pid

# Uncomment to use a multicast NTP server on the local subnet:
#multicastclient 224.0.1.1		# listen on default 224.0.1.1
# Set an optional compensation for broadcast packet delay:
#broadcastdelay	0.008

#
# Keys file.  If you want to diddle your server at run time, make a
# keys file (mode 640 owned by root:ntp) and define the key number to
# be used for making requests.
# PLEASE DO NOT USE THE DEFAULT VALUES HERE. Pick your own, or remote
# systems might be able to reset your clock at will.
