# This command normally mobilizes a persistent client mode association with the
# specified remote server or local reference clock. If the preempt flag is
# specified, a preemptable association is mobilized instead. In client mode the
# client clock can synchronize to the remote server or local reference clock,
# but the remote server can never be synchronized to the client clock.

# Restrict the accessibility
# - ignore
# Deny packets of all kinds, including ntpq and ntpdc queries.
# - nomodify
# Deny ntpq and ntpdc queries which attempt to modify the state of the server
# (i.e., run time reconfiguration). Queries which return information are
# permitted.
# - notrap
# Decline to provide mode 6 control message trap service to matching hosts.
# The trap service is a subsystem of the ntpq control message protocol which
# is intended for use by remote event logging programs.
# - noquery
# Deny ntpq and ntpdc queries. Time service is not affected.
