# --- GENERAL CONFIGURATION ---

#

# 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 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.

# 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.

# Keys file.  If you want to diddle your server at run time, make a

# PLEASE DO NOT USE THE DEFAULT VALUES HERE. Pick your own, or remote

# systems might be able to reset your clock at will. Note also that

# ntpd is started with a -A flag, disabling authentication, that

# will have to be removed as well.
