+# depsver.mf	included in Makefile.am for directories with .deps

+# When building in the same directory with sources that change over
+# time, such as when tracking using bk, the .deps files can become
+# stale with respect to moved, deleted, or superceded headers.  Most
+# commonly, this would exhibit as make reporting a failure to make a
+# header file which is no longer in the location given.  To address
+# this issue, we use a deps-ver file which is updated with each change
+# that breaks old .deps files.  A copy of deps-ver is made into
+# $(DEPDIR) if not already present.  If $(DEPDIR)/deps-ver is present
+# with different contents than deps-ver, we make clean to ensure all
+# .o files built before the incompatible change are rebuilt along with
+# their updated .deps files, then remove $(DEPDIR) and recreate it as
+# empty stubs.
+#
+# It is normal when configured with --disable-dependency-tracking for
+# the DEPDIR to not have been created.  For this reason, we use the
+# intermediate target .deps-ver, which invokes make recursively if
+# DEPDIR exists.
+#
+# If you modify depsver.mf, please make the changes to the master
+# copy, the one in sntp is copied by the bootstrap script from it.

+@code{ntpdc}
+is a utility program used to query
+@code{ntpd(1ntpdmdoc)}
+about its
+current state and to request changes in that state.
+It uses NTP mode 7 control message formats described in the source code.
+The program may
+be run either in interactive mode or controlled using command line
+arguments.
+Extensive state and statistics information is available
+through the
+@code{ntpdc}
+interface.
+In addition, nearly all the
+configuration options which can be specified at startup using
+ntpd's configuration file may also be specified at run time using
+@code{ntpdc}

+
+@node ntpdc config
+@subsection presetting/configuring ntpdc
+
+Any option that is not marked as @i{not presettable} may be preset by
+loading values from configuration ("rc" or "ini") files, and values from environment variables named @code{NTPDC} and @code{NTPDC_<OPTION_NAME>}.  @code{<OPTION_NAME>} must be one of
+the options listed above in upper case and segmented with underscores.
+The @code{NTPDC} variable will be tokenized and parsed like
+the command line.  The remaining variables are tested for existence and their
+values are treated like option arguments.
+
+
+@noindent
+@code{libopts} will search in 2 places for configuration files:
+@itemize @bullet
+@item
+$HOME
+@item
+$PWD
+@end itemize
+The environment variables @code{HOME}, and @code{PWD}
+are expanded and replaced when @file{ntpdc} runs.
+For any of these that are plain files, they are simply processed.
+For any that are directories, then a file named @file{.ntprc} is searched for
+within that directory and processed.
+
+Configuration files may be in a wide variety of formats.
+The basic format is an option name followed by a value (argument) on the
+same line.  Values may be separated from the option name with a colon,
+equal sign or simply white space.  Values may be continued across multiple
+lines by escaping the newline with a backslash.
+
+Multiple programs may also share the same initialization file.
+Common options are collected at the top, followed by program specific
+segments.  The segments are separated by lines like:
+@example
+[NTPDC]
+@end example
+@noindent
+or by
+@example
+<?program ntpdc>
+@end example
+@noindent
+Do not mix these styles within one configuration file.
+
+Compound values and carefully constructed string values may also be
+specified using XML syntax:
+@example
+<option-name>
+   <sub-opt>...&lt;...&gt;...</sub-opt>
+</option-name>
+@end example
+@noindent
+yielding an @code{option-name.sub-opt} string value of
+@example
+"...<...>..."
+@end example
+@code{AutoOpts} does not track suboptions.  You simply note that it is a
+hierarchicly valued option.  @code{AutoOpts} does provide a means for searching
+the associated name/value pair list (see: optionFindValue).
+
+The command line options relating to configuration and/or usage help are:
+
+@subsubheading version (-)
+
+Print the program version to standard out, optionally with licensing
+information, then exit 0.  The optional argument specifies how much licensing
+detail to provide.  The default is to print just the version.  The licensing infomation may be selected with an option argument.
+Only the first letter of the argument is examined:
+
+@table @samp
+@item version
+Only print the version.  This is the default.
+@item copyright
+Name the copyright usage licensing terms.
+@item verbose
+Print the full copyright usage licensing terms.
+@end table
+
+@node ntpdc exit status
+@subsection ntpdc exit status
+
+One of the following exit values will be returned:
+@table @samp
+@item 0 (EXIT_SUCCESS)
+Successful program execution.
+@item 1 (EXIT_FAILURE)
+The operation failed or the command syntax was not valid.
+@item 66 (EX_NOINPUT)
+A specified configuration file could not be loaded.
+@item 70 (EX_SOFTWARE)
+libopts had an internal operational error.  Please report
+it to autogen-users@@lists.sourceforge.net.  Thank you.

+.Pp

+is a utility program used to query

+It uses NTP mode 7 control message formats described in the source code.
+The program may
+be run either in interactive mode or controlled using command line
+arguments.
+Extensive state and statistics information is available
+through the
+.Nm
+interface.
+In addition, nearly all the
+configuration options which can be specified at startup using
+ntpd's configuration file may also be specified at run time using
+.Nm .

+If one or more request options are included on the command line
+when
+.Nm
+is executed, each of the requests will be sent
+to the NTP servers running on each of the hosts given as command
+line arguments, or on localhost by default.
+If no request options
+are given,
+.Nm
+will attempt to read commands from the
+standard input and execute these on the NTP server running on the
+first host given on the command line, again defaulting to localhost
+when no other host is specified.
+The
+.Nm
+utility will prompt for
+commands if the standard input is a terminal device.
+.Pp
+The
+.Nm
+utility uses NTP mode 7 packets to communicate with the
+NTP server, and hence can be used to query any compatible server on
+the network which permits it.
+Note that since NTP is a UDP protocol
+this communication will be somewhat unreliable, especially over
+large distances in terms of network topology.
+The
+.Nm
+utility makes
+no attempt to retransmit requests, and will time requests out if
+the remote host is not heard from within a suitable timeout
+time.
+.Pp
+The operation of
+.Nm
+are specific to the particular
+implementation of the
+.Xr ntpd 1ntpdmdoc
+daemon and can be expected to
+work only with this and maybe some previous versions of the daemon.
+Requests from a remote
+.Nm
+utility which affect the
+state of the local server must be authenticated, which requires
+both the remote program and local server share a common key and key
+identifier.
+.Pp
+Note that in contexts where a host name is expected, a
+.Fl 4
+qualifier preceding the host name forces DNS resolution to the IPv4 namespace,
+while a
+.Fl 6
+qualifier forces DNS resolution to the IPv6 namespace.
+Specifying a command line option other than
+.Fl i
+or
+.Fl n
+will cause the specified query (queries) to be sent to
+the indicated host(s) immediately.
+Otherwise,
+.Nm
+will
+attempt to read interactive format commands from the standard
+input.
+.Ss "Interactive Commands"
+Interactive format commands consist of a keyword followed by zero
+to four arguments.
+Only enough characters of the full keyword to
+uniquely identify the command need be typed.
+The output of a
+command is normally sent to the standard output, but optionally the
+output of individual commands may be sent to a file by appending a
+.Ql \&> ,
+followed by a file name, to the command line.
+.Pp
+A number of interactive format commands are executed entirely
+within the
+.Nm
+utility itself and do not result in NTP
+mode 7 requests being sent to a server.
+These are described
+following.
+.Bl -tag -width indent
+.It Ic \&? Ar command_keyword
+.It Ic help Ar command_keyword
+A
+.Sq Ic \&?
+will print a list of all the command
+keywords known to this incarnation of
+.Nm .
+A
+.Sq Ic \&?
+followed by a command keyword will print function and usage
+information about the command.
+This command is probably a better
+source of information about
+.Xr ntpq 1ntpqmdoc
+than this manual
+page.
+.It Ic delay Ar milliseconds
+Specify a time interval to be added to timestamps included in
+requests which require authentication.
+This is used to enable
+(unreliable) server reconfiguration over long delay network paths
+or between machines whose clocks are unsynchronized.
+Actually the
+server does not now require timestamps in authenticated requests,
+so this command may be obsolete.
+.It Ic host Ar hostname
+Set the host to which future queries will be sent.
+Hostname may
+be either a host name or a numeric address.
+.It Ic hostnames Op Cm yes | Cm no
+If
+.Cm yes
+is specified, host names are printed in
+information displays.
+If
+.Cm no
+is specified, numeric
+addresses are printed instead.
+The default is
+.Cm yes ,
+unless
+modified using the command line
+.Fl n
+switch.
+.It Ic keyid Ar keyid
+This command allows the specification of a key number to be
+used to authenticate configuration requests.
+This must correspond
+to a key number the server has been configured to use for this
+purpose.
+.It Ic quit
+Exit
+.Nm .
+.It Ic passwd
+This command prompts you to type in a password (which will not
+be echoed) which will be used to authenticate configuration
+requests.
+The password must correspond to the key configured for
+use by the NTP server for this purpose if such requests are to be
+successful.
+.It Ic timeout Ar milliseconds
+Specify a timeout period for responses to server queries.
+The
+default is about 8000 milliseconds.
+Note that since
+.Nm
+retries each query once after a timeout, the total waiting time for
+a timeout will be twice the timeout value set.
+.El
+.Ss "Control Message Commands"
+Query commands result in NTP mode 7 packets containing requests for
+information being sent to the server.
+These are read-only commands
+in that they make no modification of the server configuration
+state.
+.Bl -tag -width indent
+.It Ic listpeers
+Obtains and prints a brief list of the peers for which the
+server is maintaining state.
+These should include all configured
+peer associations as well as those peers whose stratum is such that
+they are considered by the server to be possible future
+synchronization candidates.
+.It Ic peers
+Obtains a list of peers for which the server is maintaining
+state, along with a summary of that state.
+Summary information
+includes the address of the remote peer, the local interface
+address (0.0.0.0 if a local address has yet to be determined), the
+stratum of the remote peer (a stratum of 16 indicates the remote
+peer is unsynchronized), the polling interval, in seconds, the
+reachability register, in octal, and the current estimated delay,
+offset and dispersion of the peer, all in seconds.
+.Pp
+The character in the left margin indicates the mode this peer
+entry is operating in.
+A
+.Ql \&+
+denotes symmetric active, a
+.Ql \&-
+indicates symmetric passive, a
+.Ql \&=
+means the
+remote server is being polled in client mode, a
+.Ql \&^
+indicates that the server is broadcasting to this address, a
+.Ql \&~
+denotes that the remote peer is sending broadcasts and a
+.Ql \&~
+denotes that the remote peer is sending broadcasts and a
+.Ql \&*
+marks the peer the server is currently synchronizing
+to.
+.Pp
+The contents of the host field may be one of four forms.
+It may
+be a host name, an IP address, a reference clock implementation
+name with its parameter or
+.Fn REFCLK "implementation_number" "parameter" .
+On

+A slightly different peer summary list.
+Identical to the output
+of the
+.Ic peers
+command, except for the character in the
+leftmost column.
+Characters only appear beside peers which were
+included in the final stage of the clock selection algorithm.
+A
+.Ql \&.
+indicates that this peer was cast off in the falseticker
+detection, while a
+.Ql \&+
+indicates that the peer made it
+through.
+A
+.Ql \&*
+denotes the peer the server is currently
+synchronizing with.
+.It Ic showpeer Ar peer_address Oo Ar ... Oc
+Shows a detailed display of the current peer variables for one
+or more peers.
+Most of these values are described in the NTP
+Version 2 specification.
+.It Ic pstats Ar peer_address Oo Ar ... Oc
+Show per-peer statistic counters associated with the specified
+peer(s).
+.It Ic clockstat Ar clock_peer_address Oo Ar ... Oc
+Obtain and print information concerning a peer clock.
+The
+values obtained provide information on the setting of fudge factors
+and other clock performance information.
+.It Ic kerninfo
+Obtain and print kernel phase-lock loop operating parameters.
+This information is available only if the kernel has been specially
+modified for a precision timekeeping function.
+.It Ic loopinfo Op Cm oneline | Cm multiline
+Print the values of selected loop filter variables.
+The loop
+filter is the part of NTP which deals with adjusting the local
+system clock.
+The
+.Sq offset
+is the last offset given to the
+loop filter by the packet processing code.
+The
+.Sq frequency
+is the frequency error of the local clock in parts-per-million
+(ppm).
+The
+.Sq time_const
+controls the stiffness of the
+phase-lock loop and thus the speed at which it can adapt to
+oscillator drift.
+The
+.Sq watchdog timer
+value is the number
+of seconds which have elapsed since the last sample offset was
+given to the loop filter.
+The
+.Cm oneline
+and
+.Cm multiline
+options specify the format in which this
+information is to be printed, with
+.Cm multiline
+as the
+default.
+.It Ic sysinfo
+Print a variety of system state variables, i.e., state related
+to the local server.
+All except the last four lines are described
+in the NTP Version 3 specification, RFC-1305.
+.Pp
+The
+.Sq system flags
+show various system flags, some of
+which can be set and cleared by the
+.Ic enable
+and
+.Ic disable
+configuration commands, respectively.
+These are
+the
+.Cm auth ,
+.Cm bclient ,
+.Cm monitor ,
+.Cm pll ,
+.Cm pps
+and
+.Cm stats
+flags.
+See the
+.Xr ntpd 1ntpdmdoc
+documentation for the meaning of these flags.
+There
+are two additional flags which are read only, the
+.Cm kernel_pll
+and
+.Cm kernel_pps .
+These flags indicate
+the synchronization status when the precision time kernel
+modifications are in use.
+The
+.Sq kernel_pll
+indicates that
+the local clock is being disciplined by the kernel, while the
+.Sq kernel_pps
+indicates the kernel discipline is provided by the PPS
+signal.
+.Pp
+The
+.Sq stability
+is the residual frequency error remaining
+after the system frequency correction is applied and is intended for
+maintenance and debugging.
+In most architectures, this value will
+initially decrease from as high as 500 ppm to a nominal value in
+the range .01 to 0.1 ppm.
+If it remains high for some time after
+starting the daemon, something may be wrong with the local clock,
+or the value of the kernel variable
+.Va kern.clockrate.tick
+may be
+incorrect.
+.Pp
+The
+.Sq broadcastdelay
+shows the default broadcast delay,
+as set by the
+.Ic broadcastdelay
+configuration command.
+.Pp
+The
+.Sq authdelay
+shows the default authentication delay,
+as set by the
+.Ic authdelay
+configuration command.
+.It Ic sysstats
+Print statistics counters maintained in the protocol
+module.
+.It Ic memstats
+Print statistics counters related to memory allocation
+code.
+.It Ic iostats
+Print statistics counters maintained in the input-output
+module.
+.It Ic timerstats
+Print statistics counters maintained in the timer/event queue
+support code.
+.It Ic reslist
+Obtain and print the server's restriction list.
+This list is
+(usually) printed in sorted order and may help to understand how
+the restrictions are applied.
+.It Ic monlist Op Ar version
+Obtain and print traffic counts collected and maintained by the
+monitor facility.
+The version number should not normally need to be
+specified.
+.It Ic clkbug Ar clock_peer_address Oo Ar ... Oc
+Obtain debugging information for a reference clock driver.
+This
+information is provided only by some clock drivers and is mostly
+undecodable without a copy of the driver source in hand.
+.El
+.Ss "Runtime Configuration Requests"
+All requests which cause state changes in the server are
+authenticated by the server using a configured NTP key (the
+facility can also be disabled by the server by not configuring a
+key).
+The key number and the corresponding key must also be made
+known to
+.Nm .
+This can be done using the
+.Ic keyid
+and
+.Ic passwd
+commands, the latter of which will prompt at the terminal for a
+password to use as the encryption key.
+You will also be prompted
+automatically for both the key number and password the first time a
+command which would result in an authenticated request to the
+server is given.
+Authentication not only provides verification that
+the requester has permission to make such changes, but also gives
+an extra degree of protection again transmission errors.
+.Pp
+Authenticated requests always include a timestamp in the packet
+data, which is included in the computation of the authentication
+code.
+This timestamp is compared by the server to its receive time
+stamp.
+If they differ by more than a small amount the request is
+rejected.
+This is done for two reasons.
+First, it makes simple
+replay attacks on the server, by someone who might be able to
+overhear traffic on your LAN, much more difficult.
+Second, it makes
+it more difficult to request configuration changes to your server
+from topologically remote hosts.
+While the reconfiguration facility
+will work well with a server on the local host, and may work
+adequately between time-synchronized hosts on the same LAN, it will
+work very poorly for more distant hosts.
+As such, if reasonable
+passwords are chosen, care is taken in the distribution and
+protection of keys and appropriate source address restrictions are
+applied, the run time reconfiguration facility should provide an
+adequate level of security.
+.Pp
+The following commands all make authenticated requests.
+.Bl -tag -width indent
+.It Xo Ic addpeer Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Add a configured peer association at the given address and
+operating in symmetric active mode.
+Note that an existing
+association with the same peer may be deleted when this command is
+executed, or may simply be converted to conform to the new
+configuration, as appropriate.
+If the optional
+.Ar keyid
+is a
+nonzero integer, all outgoing packets to the remote server will
+have an authentication field attached encrypted with this key.
+If
+the value is 0 (or not given) no authentication will be done.
+The
+.Ar version
+can be 1, 2 or 3 and defaults to 3.
+The
+.Cm prefer
+keyword indicates a preferred peer (and thus will
+be used primarily for clock synchronisation if possible).
+The
+preferred peer also determines the validity of the PPS signal - if
+the preferred peer is suitable for synchronisation so is the PPS
+signal.
+.It Xo Ic addserver Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Identical to the addpeer command, except that the operating
+mode is client.
+.It Xo Ic broadcast Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Identical to the addpeer command, except that the operating
+mode is broadcast.
+In this case a valid key identifier and key are
+required.
+The
+.Ar peer_address
+parameter can be the broadcast
+address of the local network or a multicast group address assigned
+to NTP.
+If a multicast address, a multicast-capable kernel is
+required.
+.It Ic unconfig Ar peer_address Oo Ar ... Oc
+This command causes the configured bit to be removed from the
+specified peer(s).
+In many cases this will cause the peer
+association to be deleted.
+When appropriate, however, the
+association may persist in an unconfigured mode if the remote peer
+is willing to continue on in this fashion.
+.It Xo Ic fudge Ar peer_address
+.Op Cm time1
+.Op Cm time2
+.Op Ar stratum
+.Op Ar refid
+.Xc
+This command provides a way to set certain data for a reference
+clock.
+See the source listing for further information.

+configuration file).
+This
+allows encryption keys to be changed without restarting the

+.SH DESCRIPTION
+\f\*[B-Font]ntpdc\fP
+is deprecated.
+Please use
+\fCntpq\fR(1ntpqmdoc)\f[] instead \- it can do everything
+\f\*[B-Font]ntpdc\fP
+used to do, and it does so using a much more sane interface.
+.sp \n(Ppu
+.ne 2
+
+\f\*[B-Font]ntpdc\fP
+is a utility program used to query
+\fCntpd\fR(1ntpdmdoc)\f[]
+about its
+current state and to request changes in that state.
+It uses NTP mode 7 control message formats described in the source code.
+The program may
+be run either in interactive mode or controlled using command line
+arguments.
+Extensive state and statistics information is available
+through the
+\f\*[B-Font]ntpdc\fP
+interface.
+In addition, nearly all the
+configuration options which can be specified at startup using
+ntpd's configuration file may also be specified at run time using
+\f\*[B-Font]ntpdc\fP.

+.SH "OPTION PRESETS"
+Any option that is not marked as \fInot presettable\fP may be preset
+by loading values from configuration ("RC" or ".INI") file(s) and values from
+environment variables named:
+.nf
+  \fBNTPDC_<option-name>\fP or \fBNTPDC\fP
+.fi
+.ad
+The environmental presets take precedence (are processed later than)
+the configuration files.
+The \fIhomerc\fP files are "\fI$HOME\fP", and "\fI.\fP".
+If any of these are directories, then the file \fI.ntprc\fP
+is searched for within those directories.
+.SH USAGE
+If one or more request options are included on the command line
+when
+\f\*[B-Font]ntpdc\fP
+is executed, each of the requests will be sent
+to the NTP servers running on each of the hosts given as command
+line arguments, or on localhost by default.
+If no request options
+are given,
+\f\*[B-Font]ntpdc\fP
+will attempt to read commands from the
+standard input and execute these on the NTP server running on the
+first host given on the command line, again defaulting to localhost
+when no other host is specified.
+The
+\f\*[B-Font]ntpdc\fP
+utility will prompt for
+commands if the standard input is a terminal device.
+.sp \n(Ppu
+.ne 2
+
+The
+\f\*[B-Font]ntpdc\fP
+utility uses NTP mode 7 packets to communicate with the
+NTP server, and hence can be used to query any compatible server on
+the network which permits it.
+Note that since NTP is a UDP protocol
+this communication will be somewhat unreliable, especially over
+large distances in terms of network topology.
+The
+\f\*[B-Font]ntpdc\fP
+utility makes
+no attempt to retransmit requests, and will time requests out if
+the remote host is not heard from within a suitable timeout
+time.
+.sp \n(Ppu
+.ne 2
+
+The operation of
+\f\*[B-Font]ntpdc\fP
+are specific to the particular
+implementation of the
+\fCntpd\fR(1ntpdmdoc)\f[]
+daemon and can be expected to
+work only with this and maybe some previous versions of the daemon.
+Requests from a remote
+\f\*[B-Font]ntpdc\fP
+utility which affect the
+state of the local server must be authenticated, which requires
+both the remote program and local server share a common key and key
+identifier.
+.sp \n(Ppu
+.ne 2
+
+Note that in contexts where a host name is expected, a
+\f\*[B-Font]\-4\f[]
+qualifier preceding the host name forces DNS resolution to the IPv4 namespace,
+while a
+\f\*[B-Font]\-6\f[]
+qualifier forces DNS resolution to the IPv6 namespace.
+Specifying a command line option other than
+\f\*[B-Font]\-i\f[]
+or
+\f\*[B-Font]\-n\f[]
+will cause the specified query (queries) to be sent to
+the indicated host(s) immediately.
+Otherwise,
+\f\*[B-Font]ntpdc\fP
+will
+attempt to read interactive format commands from the standard
+input.
+.SS "Interactive Commands"
+Interactive format commands consist of a keyword followed by zero
+to four arguments.
+Only enough characters of the full keyword to
+uniquely identify the command need be typed.
+The output of a
+command is normally sent to the standard output, but optionally the
+output of individual commands may be sent to a file by appending a
+\[oq]\&>\[cq],
+followed by a file name, to the command line.
+.sp \n(Ppu
+.ne 2
+
+A number of interactive format commands are executed entirely
+within the
+\f\*[B-Font]ntpdc\fP
+utility itself and do not result in NTP
+mode 7 requests being sent to a server.
+These are described
+following.
+.TP 7
+.NOP \f\*[B-Font]\&?\f[] \f\*[I-Font]command_keyword\f[]
+.TP 7
+.NOP \f\*[B-Font]help\f[] \f\*[I-Font]command_keyword\f[]
+A
+\[oq]\f\*[B-Font]\&?\f[]\[cq]
+will print a list of all the command
+keywords known to this incarnation of
+\f\*[B-Font]ntpdc\fP.
+A
+\[oq]\f\*[B-Font]\&?\f[]\[cq]
+followed by a command keyword will print function and usage
+information about the command.
+This command is probably a better
+source of information about
+\fCntpq\fR(1ntpqmdoc)\f[]
+than this manual
+page.
+.TP 7
+.NOP \f\*[B-Font]delay\f[] \f\*[I-Font]milliseconds\f[]
+Specify a time interval to be added to timestamps included in
+requests which require authentication.
+This is used to enable
+(unreliable) server reconfiguration over long delay network paths
+or between machines whose clocks are unsynchronized.
+Actually the
+server does not now require timestamps in authenticated requests,
+so this command may be obsolete.
+.TP 7
+.NOP \f\*[B-Font]host\f[] \f\*[I-Font]hostname\f[]
+Set the host to which future queries will be sent.
+Hostname may
+be either a host name or a numeric address.
+.TP 7
+.NOP \f\*[B-Font]hostnames\f[] [\f\*[B-Font]yes\f[] | \f\*[B-Font]no\f[]]
+If
+\f\*[B-Font]yes\f[]
+is specified, host names are printed in
+information displays.
+If
+\f\*[B-Font]no\f[]
+is specified, numeric
+addresses are printed instead.
+The default is
+\f\*[B-Font]yes\f[],
+unless
+modified using the command line
+\f\*[B-Font]\-n\f[]
+switch.
+.TP 7
+.NOP \f\*[B-Font]keyid\f[] \f\*[I-Font]keyid\f[]
+This command allows the specification of a key number to be
+used to authenticate configuration requests.
+This must correspond
+to a key number the server has been configured to use for this
+purpose.
+.TP 7
+.NOP \f\*[B-Font]quit\f[]
+Exit
+\f\*[B-Font]ntpdc\fP.
+.TP 7
+.NOP \f\*[B-Font]passwd\f[]
+This command prompts you to type in a password (which will not
+be echoed) which will be used to authenticate configuration
+requests.
+The password must correspond to the key configured for
+use by the NTP server for this purpose if such requests are to be
+successful.
+.TP 7
+.NOP \f\*[B-Font]timeout\f[] \f\*[I-Font]milliseconds\f[]
+Specify a timeout period for responses to server queries.
+The
+default is about 8000 milliseconds.
+Note that since
+\f\*[B-Font]ntpdc\fP
+retries each query once after a timeout, the total waiting time for
+a timeout will be twice the timeout value set.
+.PP
+.SS "Control Message Commands"
+Query commands result in NTP mode 7 packets containing requests for
+information being sent to the server.
+These are read-only commands
+in that they make no modification of the server configuration
+state.
+.TP 7
+.NOP \f\*[B-Font]listpeers\f[]
+Obtains and prints a brief list of the peers for which the
+server is maintaining state.
+These should include all configured
+peer associations as well as those peers whose stratum is such that
+they are considered by the server to be possible future
+synchronization candidates.
+.TP 7
+.NOP \f\*[B-Font]peers\f[]
+Obtains a list of peers for which the server is maintaining
+state, along with a summary of that state.
+Summary information
+includes the address of the remote peer, the local interface
+address (0.0.0.0 if a local address has yet to be determined), the
+stratum of the remote peer (a stratum of 16 indicates the remote
+peer is unsynchronized), the polling interval, in seconds, the
+reachability register, in octal, and the current estimated delay,
+offset and dispersion of the peer, all in seconds.
+.sp \n(Ppu
+.ne 2
+
+The character in the left margin indicates the mode this peer
+entry is operating in.
+A
+\[oq]\&+\[cq]
+denotes symmetric active, a
+\[oq]\&-\[cq]
+indicates symmetric passive, a
+\[oq]\&=\[cq]
+means the
+remote server is being polled in client mode, a
+\[oq]\&^\[cq]
+indicates that the server is broadcasting to this address, a
+\[oq]\&~\[cq]
+denotes that the remote peer is sending broadcasts and a
+\[oq]\&~\[cq]
+denotes that the remote peer is sending broadcasts and a
+\[oq]\&*\[cq]
+marks the peer the server is currently synchronizing
+to.
+.sp \n(Ppu
+.ne 2
+
+The contents of the host field may be one of four forms.
+It may
+be a host name, an IP address, a reference clock implementation
+name with its parameter or
+\fBREFCLK\fR()\f[]
+On
+\f\*[B-Font]hostnames\f[]
+\f\*[B-Font]no\f[]
+only IP-addresses
+will be displayed.
+.TP 7
+.NOP \f\*[B-Font]dmpeers\f[]
+A slightly different peer summary list.
+Identical to the output
+of the
+\f\*[B-Font]peers\f[]
+command, except for the character in the
+leftmost column.
+Characters only appear beside peers which were
+included in the final stage of the clock selection algorithm.
+A
+\[oq]\&.\[cq]
+indicates that this peer was cast off in the falseticker
+detection, while a
+\[oq]\&+\[cq]
+indicates that the peer made it
+through.
+A
+\[oq]\&*\[cq]
+denotes the peer the server is currently
+synchronizing with.
+.TP 7
+.NOP \f\*[B-Font]showpeer\f[] \f\*[I-Font]peer_address\f[] [\f\*[I-Font]...\f[]]
+Shows a detailed display of the current peer variables for one
+or more peers.
+Most of these values are described in the NTP
+Version 2 specification.
+.TP 7
+.NOP \f\*[B-Font]pstats\f[] \f\*[I-Font]peer_address\f[] [\f\*[I-Font]...\f[]]
+Show per-peer statistic counters associated with the specified
+peer(s).
+.TP 7
+.NOP \f\*[B-Font]clockstat\f[] \f\*[I-Font]clock_peer_address\f[] [\f\*[I-Font]...\f[]]
+Obtain and print information concerning a peer clock.
+The
+values obtained provide information on the setting of fudge factors
+and other clock performance information.
+.TP 7
+.NOP \f\*[B-Font]kerninfo\f[]
+Obtain and print kernel phase-lock loop operating parameters.
+This information is available only if the kernel has been specially
+modified for a precision timekeeping function.
+.TP 7
+.NOP \f\*[B-Font]loopinfo\f[] [\f\*[B-Font]oneline\f[] | \f\*[B-Font]multiline\f[]]
+Print the values of selected loop filter variables.
+The loop
+filter is the part of NTP which deals with adjusting the local
+system clock.
+The
+\[oq]offset\[cq]
+is the last offset given to the
+loop filter by the packet processing code.
+The
+\[oq]frequency\[cq]
+is the frequency error of the local clock in parts-per-million
+(ppm).
+The
+\[oq]time_const\[cq]
+controls the stiffness of the
+phase-lock loop and thus the speed at which it can adapt to
+oscillator drift.
+The
+\[oq]watchdog timer\[cq]
+value is the number
+of seconds which have elapsed since the last sample offset was
+given to the loop filter.
+The
+\f\*[B-Font]oneline\f[]
+and
+\f\*[B-Font]multiline\f[]
+options specify the format in which this
+information is to be printed, with
+\f\*[B-Font]multiline\f[]
+as the
+default.
+.TP 7
+.NOP \f\*[B-Font]sysinfo\f[]
+Print a variety of system state variables, i.e., state related
+to the local server.
+All except the last four lines are described
+in the NTP Version 3 specification, RFC-1305.
+.sp \n(Ppu
+.ne 2
+
+The
+\[oq]system flags\[cq]
+show various system flags, some of
+which can be set and cleared by the
+\f\*[B-Font]enable\f[]
+and
+\f\*[B-Font]disable\f[]
+configuration commands, respectively.
+These are
+the

+\f\*[B-Font]bclient\f[],
+\f\*[B-Font]monitor\f[],
+\f\*[B-Font]pll\f[],
+\f\*[B-Font]pps\f[]
+and
+\f\*[B-Font]stats\f[]
+flags.
+See the
+\fCntpd\fR(1ntpdmdoc)\f[]
+documentation for the meaning of these flags.
+There
+are two additional flags which are read only, the
+\f\*[B-Font]kernel_pll\f[]
+and
+\f\*[B-Font]kernel_pps\f[].
+These flags indicate
+the synchronization status when the precision time kernel
+modifications are in use.
+The
+\[oq]kernel_pll\[cq]
+indicates that
+the local clock is being disciplined by the kernel, while the
+\[oq]kernel_pps\[cq]
+indicates the kernel discipline is provided by the PPS
+signal.
+.sp \n(Ppu
+.ne 2
+
+The
+\[oq]stability\[cq]
+is the residual frequency error remaining
+after the system frequency correction is applied and is intended for
+maintenance and debugging.
+In most architectures, this value will
+initially decrease from as high as 500 ppm to a nominal value in
+the range .01 to 0.1 ppm.
+If it remains high for some time after
+starting the daemon, something may be wrong with the local clock,
+or the value of the kernel variable
+\fIkern.clockrate.tick\f[]
+may be
+incorrect.

+Print statistics counters maintained in the timer/event queue
+support code.
+.TP 7
+.NOP \f\*[B-Font]reslist\f[]

+Obtain debugging information for a reference clock driver.
+This
+information is provided only by some clock drivers and is mostly
+undecodable without a copy of the driver source in hand.
+.PP
+.SS "Runtime Configuration Requests"
+All requests which cause state changes in the server are
+authenticated by the server using a configured NTP key (the
+facility can also be disabled by the server by not configuring a
+key).
+The key number and the corresponding key must also be made
+known to
+\f\*[B-Font]ntpdc\fP.
+This can be done using the
+\f\*[B-Font]keyid\f[]
+and
+\f\*[B-Font]passwd\f[]
+commands, the latter of which will prompt at the terminal for a
+password to use as the encryption key.
+You will also be prompted
+automatically for both the key number and password the first time a
+command which would result in an authenticated request to the
+server is given.
+Authentication not only provides verification that
+the requester has permission to make such changes, but also gives
+an extra degree of protection again transmission errors.
+.sp \n(Ppu
+.ne 2
+
+Authenticated requests always include a timestamp in the packet
+data, which is included in the computation of the authentication
+code.
+This timestamp is compared by the server to its receive time
+stamp.
+If they differ by more than a small amount the request is
+rejected.
+This is done for two reasons.
+First, it makes simple
+replay attacks on the server, by someone who might be able to
+overhear traffic on your LAN, much more difficult.
+Second, it makes
+it more difficult to request configuration changes to your server
+from topologically remote hosts.
+While the reconfiguration facility
+will work well with a server on the local host, and may work
+adequately between time-synchronized hosts on the same LAN, it will
+work very poorly for more distant hosts.
+As such, if reasonable
+passwords are chosen, care is taken in the distribution and
+protection of keys and appropriate source address restrictions are
+applied, the run time reconfiguration facility should provide an
+adequate level of security.
+.sp \n(Ppu

+Add a configured peer association at the given address and
+operating in symmetric active mode.
+Note that an existing
+association with the same peer may be deleted when this command is
+executed, or may simply be converted to conform to the new
+configuration, as appropriate.
+If the optional
+\f\*[I-Font]keyid\f[]
+is a
+nonzero integer, all outgoing packets to the remote server will
+have an authentication field attached encrypted with this key.
+If
+the value is 0 (or not given) no authentication will be done.
+The
+\f\*[I-Font]version\f[]
+can be 1, 2 or 3 and defaults to 3.
+The
+\f\*[B-Font]prefer\f[]
+keyword indicates a preferred peer (and thus will
+be used primarily for clock synchronisation if possible).
+The
+preferred peer also determines the validity of the PPS signal \- if
+the preferred peer is suitable for synchronisation so is the PPS
+signal.

+[ host ...]
+.Pp
+.Sh DESCRIPTION
+.Nm
+is deprecated.
+Please use
+.Xr ntpq 1ntpqmdoc instead \- it can do everything
+.Nm
+used to do, and it does so using a much more sane interface.
+.Pp
+.Nm
+is a utility program used to query
+.Xr ntpd 1ntpdmdoc
+about its
+current state and to request changes in that state.
+It uses NTP mode 7 control message formats described in the source code.
+The program may
+be run either in interactive mode or controlled using command line
+arguments.
+Extensive state and statistics information is available
+through the
+.Nm
+interface.
+In addition, nearly all the
+configuration options which can be specified at startup using
+ntpd's configuration file may also be specified at run time using
+.Nm .

+print the full copyright notice.
+.El
+.Sh "OPTION PRESETS"
+Any option that is not marked as \fInot presettable\fP may be preset
+by loading values from configuration ("RC" or ".INI") file(s) and values from
+environment variables named:
+.nf
+  \fBNTPDC_<option\-name>\fP or \fBNTPDC\fP
+.fi
+.ad
+The environmental presets take precedence (are processed later than)
+the configuration files.
+The \fIhomerc\fP files are "\fI$HOME\fP", and "\fI.\fP".
+If any of these are directories, then the file \fI.ntprc\fP
+is searched for within those directories.
+.Sh USAGE
+If one or more request options are included on the command line
+when
+.Nm
+is executed, each of the requests will be sent
+to the NTP servers running on each of the hosts given as command
+line arguments, or on localhost by default.
+If no request options
+are given,
+.Nm
+will attempt to read commands from the
+standard input and execute these on the NTP server running on the
+first host given on the command line, again defaulting to localhost
+when no other host is specified.
+The
+.Nm
+utility will prompt for
+commands if the standard input is a terminal device.
+.Pp
+The
+.Nm
+utility uses NTP mode 7 packets to communicate with the
+NTP server, and hence can be used to query any compatible server on
+the network which permits it.
+Note that since NTP is a UDP protocol
+this communication will be somewhat unreliable, especially over
+large distances in terms of network topology.
+The
+.Nm
+utility makes
+no attempt to retransmit requests, and will time requests out if
+the remote host is not heard from within a suitable timeout
+time.
+.Pp
+The operation of
+.Nm
+are specific to the particular
+implementation of the
+.Xr ntpd 1ntpdmdoc
+daemon and can be expected to
+work only with this and maybe some previous versions of the daemon.
+Requests from a remote
+.Nm
+utility which affect the
+state of the local server must be authenticated, which requires
+both the remote program and local server share a common key and key
+identifier.
+.Pp
+Note that in contexts where a host name is expected, a
+.Fl 4
+qualifier preceding the host name forces DNS resolution to the IPv4 namespace,
+while a
+.Fl 6
+qualifier forces DNS resolution to the IPv6 namespace.
+Specifying a command line option other than
+.Fl i
+or
+.Fl n
+will cause the specified query (queries) to be sent to
+the indicated host(s) immediately.
+Otherwise,
+.Nm
+will
+attempt to read interactive format commands from the standard
+input.
+.Ss "Interactive Commands"
+Interactive format commands consist of a keyword followed by zero
+to four arguments.
+Only enough characters of the full keyword to
+uniquely identify the command need be typed.
+The output of a
+command is normally sent to the standard output, but optionally the
+output of individual commands may be sent to a file by appending a
+.Ql \&> ,
+followed by a file name, to the command line.
+.Pp
+A number of interactive format commands are executed entirely
+within the
+.Nm
+utility itself and do not result in NTP
+mode 7 requests being sent to a server.
+These are described
+following.
+.Bl -tag -width indent
+.It Ic \&? Ar command_keyword
+.It Ic help Ar command_keyword
+A
+.Sq Ic \&?
+will print a list of all the command
+keywords known to this incarnation of
+.Nm .
+A
+.Sq Ic \&?
+followed by a command keyword will print function and usage
+information about the command.
+This command is probably a better
+source of information about
+.Xr ntpq 1ntpqmdoc
+than this manual
+page.
+.It Ic delay Ar milliseconds
+Specify a time interval to be added to timestamps included in
+requests which require authentication.
+This is used to enable
+(unreliable) server reconfiguration over long delay network paths
+or between machines whose clocks are unsynchronized.
+Actually the
+server does not now require timestamps in authenticated requests,
+so this command may be obsolete.
+.It Ic host Ar hostname
+Set the host to which future queries will be sent.
+Hostname may
+be either a host name or a numeric address.
+.It Ic hostnames Op Cm yes | Cm no
+If
+.Cm yes
+is specified, host names are printed in
+information displays.
+If
+.Cm no
+is specified, numeric
+addresses are printed instead.
+The default is
+.Cm yes ,
+unless
+modified using the command line
+.Fl n
+switch.
+.It Ic keyid Ar keyid
+This command allows the specification of a key number to be
+used to authenticate configuration requests.
+This must correspond
+to a key number the server has been configured to use for this
+purpose.
+.It Ic quit
+Exit
+.Nm .
+.It Ic passwd
+This command prompts you to type in a password (which will not
+be echoed) which will be used to authenticate configuration
+requests.
+The password must correspond to the key configured for
+use by the NTP server for this purpose if such requests are to be
+successful.
+.It Ic timeout Ar milliseconds
+Specify a timeout period for responses to server queries.
+The
+default is about 8000 milliseconds.
+Note that since
+.Nm
+retries each query once after a timeout, the total waiting time for
+a timeout will be twice the timeout value set.
+.El
+.Ss "Control Message Commands"
+Query commands result in NTP mode 7 packets containing requests for
+information being sent to the server.
+These are read\-only commands
+in that they make no modification of the server configuration
+state.
+.Bl -tag -width indent
+.It Ic listpeers
+Obtains and prints a brief list of the peers for which the
+server is maintaining state.
+These should include all configured
+peer associations as well as those peers whose stratum is such that
+they are considered by the server to be possible future
+synchronization candidates.
+.It Ic peers
+Obtains a list of peers for which the server is maintaining
+state, along with a summary of that state.
+Summary information
+includes the address of the remote peer, the local interface
+address (0.0.0.0 if a local address has yet to be determined), the
+stratum of the remote peer (a stratum of 16 indicates the remote
+peer is unsynchronized), the polling interval, in seconds, the
+reachability register, in octal, and the current estimated delay,
+offset and dispersion of the peer, all in seconds.
+.Pp
+The character in the left margin indicates the mode this peer
+entry is operating in.
+A
+.Ql \&+
+denotes symmetric active, a
+.Ql \&\-
+indicates symmetric passive, a
+.Ql \&=
+means the
+remote server is being polled in client mode, a
+.Ql \&^
+indicates that the server is broadcasting to this address, a
+.Ql \&~
+denotes that the remote peer is sending broadcasts and a
+.Ql \&~
+denotes that the remote peer is sending broadcasts and a
+.Ql \&*
+marks the peer the server is currently synchronizing
+to.
+.Pp
+The contents of the host field may be one of four forms.
+It may
+be a host name, an IP address, a reference clock implementation
+name with its parameter or
+.Fn REFCLK "implementation_number" "parameter" .
+On
+.Ic hostnames
+.Cm no
+only IP\-addresses
+will be displayed.
+.It Ic dmpeers
+A slightly different peer summary list.
+Identical to the output
+of the
+.Ic peers
+command, except for the character in the
+leftmost column.
+Characters only appear beside peers which were
+included in the final stage of the clock selection algorithm.
+A
+.Ql \&.
+indicates that this peer was cast off in the falseticker
+detection, while a
+.Ql \&+
+indicates that the peer made it
+through.
+A
+.Ql \&*
+denotes the peer the server is currently
+synchronizing with.
+.It Ic showpeer Ar peer_address Oo Ar ... Oc
+Shows a detailed display of the current peer variables for one
+or more peers.
+Most of these values are described in the NTP
+Version 2 specification.
+.It Ic pstats Ar peer_address Oo Ar ... Oc
+Show per\-peer statistic counters associated with the specified
+peer(s).
+.It Ic clockstat Ar clock_peer_address Oo Ar ... Oc
+Obtain and print information concerning a peer clock.
+The
+values obtained provide information on the setting of fudge factors
+and other clock performance information.
+.It Ic kerninfo
+Obtain and print kernel phase\-lock loop operating parameters.
+This information is available only if the kernel has been specially
+modified for a precision timekeeping function.
+.It Ic loopinfo Op Cm oneline | Cm multiline
+Print the values of selected loop filter variables.
+The loop
+filter is the part of NTP which deals with adjusting the local
+system clock.
+The
+.Sq offset
+is the last offset given to the
+loop filter by the packet processing code.
+The
+.Sq frequency
+is the frequency error of the local clock in parts\-per\-million
+(ppm).
+The
+.Sq time_const
+controls the stiffness of the
+phase\-lock loop and thus the speed at which it can adapt to
+oscillator drift.
+The
+.Sq watchdog timer
+value is the number
+of seconds which have elapsed since the last sample offset was
+given to the loop filter.
+The
+.Cm oneline
+and
+.Cm multiline
+options specify the format in which this
+information is to be printed, with
+.Cm multiline
+as the
+default.
+.It Ic sysinfo
+Print a variety of system state variables, i.e., state related
+to the local server.
+All except the last four lines are described
+in the NTP Version 3 specification, RFC\-1305.
+.Pp
+The
+.Sq system flags
+show various system flags, some of
+which can be set and cleared by the
+.Ic enable
+and
+.Ic disable
+configuration commands, respectively.
+These are
+the
+.Cm auth ,
+.Cm bclient ,
+.Cm monitor ,
+.Cm pll ,
+.Cm pps
+and
+.Cm stats
+flags.
+See the
+.Xr ntpd 1ntpdmdoc
+documentation for the meaning of these flags.
+There
+are two additional flags which are read only, the
+.Cm kernel_pll
+and
+.Cm kernel_pps .
+These flags indicate
+the synchronization status when the precision time kernel
+modifications are in use.
+The
+.Sq kernel_pll
+indicates that
+the local clock is being disciplined by the kernel, while the
+.Sq kernel_pps
+indicates the kernel discipline is provided by the PPS
+signal.
+.Pp
+The
+.Sq stability
+is the residual frequency error remaining
+after the system frequency correction is applied and is intended for
+maintenance and debugging.
+In most architectures, this value will
+initially decrease from as high as 500 ppm to a nominal value in
+the range .01 to 0.1 ppm.
+If it remains high for some time after
+starting the daemon, something may be wrong with the local clock,
+or the value of the kernel variable
+.Va kern.clockrate.tick
+may be
+incorrect.
+.Pp
+The
+.Sq broadcastdelay
+shows the default broadcast delay,
+as set by the
+.Ic broadcastdelay
+configuration command.
+.Pp
+The
+.Sq authdelay
+shows the default authentication delay,
+as set by the
+.Ic authdelay
+configuration command.
+.It Ic sysstats
+Print statistics counters maintained in the protocol
+module.
+.It Ic memstats
+Print statistics counters related to memory allocation
+code.
+.It Ic iostats
+Print statistics counters maintained in the input\-output
+module.
+.It Ic timerstats
+Print statistics counters maintained in the timer/event queue
+support code.
+.It Ic reslist
+Obtain and print the server's restriction list.
+This list is
+(usually) printed in sorted order and may help to understand how
+the restrictions are applied.
+.It Ic monlist Op Ar version
+Obtain and print traffic counts collected and maintained by the
+monitor facility.
+The version number should not normally need to be
+specified.
+.It Ic clkbug Ar clock_peer_address Oo Ar ... Oc
+Obtain debugging information for a reference clock driver.
+This
+information is provided only by some clock drivers and is mostly
+undecodable without a copy of the driver source in hand.
+.El
+.Ss "Runtime Configuration Requests"
+All requests which cause state changes in the server are
+authenticated by the server using a configured NTP key (the
+facility can also be disabled by the server by not configuring a
+key).
+The key number and the corresponding key must also be made
+known to
+.Nm .
+This can be done using the
+.Ic keyid
+and
+.Ic passwd
+commands, the latter of which will prompt at the terminal for a
+password to use as the encryption key.
+You will also be prompted
+automatically for both the key number and password the first time a
+command which would result in an authenticated request to the
+server is given.
+Authentication not only provides verification that
+the requester has permission to make such changes, but also gives
+an extra degree of protection again transmission errors.
+.Pp
+Authenticated requests always include a timestamp in the packet
+data, which is included in the computation of the authentication
+code.
+This timestamp is compared by the server to its receive time
+stamp.
+If they differ by more than a small amount the request is
+rejected.
+This is done for two reasons.
+First, it makes simple
+replay attacks on the server, by someone who might be able to
+overhear traffic on your LAN, much more difficult.
+Second, it makes
+it more difficult to request configuration changes to your server
+from topologically remote hosts.
+While the reconfiguration facility
+will work well with a server on the local host, and may work
+adequately between time\-synchronized hosts on the same LAN, it will
+work very poorly for more distant hosts.
+As such, if reasonable
+passwords are chosen, care is taken in the distribution and
+protection of keys and appropriate source address restrictions are
+applied, the run time reconfiguration facility should provide an
+adequate level of security.

+The following commands all make authenticated requests.
+.Bl -tag -width indent
+.It Xo Ic addpeer Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Add a configured peer association at the given address and
+operating in symmetric active mode.
+Note that an existing
+association with the same peer may be deleted when this command is
+executed, or may simply be converted to conform to the new
+configuration, as appropriate.
+If the optional
+.Ar keyid
+is a
+nonzero integer, all outgoing packets to the remote server will
+have an authentication field attached encrypted with this key.
+If
+the value is 0 (or not given) no authentication will be done.
+The
+.Ar version
+can be 1, 2 or 3 and defaults to 3.
+The
+.Cm prefer
+keyword indicates a preferred peer (and thus will
+be used primarily for clock synchronisation if possible).
+The
+preferred peer also determines the validity of the PPS signal \- if
+the preferred peer is suitable for synchronisation so is the PPS
+signal.
+.It Xo Ic addserver Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Identical to the addpeer command, except that the operating
+mode is client.
+.It Xo Ic broadcast Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Identical to the addpeer command, except that the operating
+mode is broadcast.
+In this case a valid key identifier and key are
+required.
+The
+.Ar peer_address
+parameter can be the broadcast
+address of the local network or a multicast group address assigned
+to NTP.
+If a multicast address, a multicast\-capable kernel is
+required.
+.It Ic unconfig Ar peer_address Oo Ar ... Oc
+This command causes the configured bit to be removed from the
+specified peer(s).
+In many cases this will cause the peer
+association to be deleted.
+When appropriate, however, the
+association may persist in an unconfigured mode if the remote peer
+is willing to continue on in this fashion.
+.It Xo Ic fudge Ar peer_address
+.Op Cm time1
+.Op Cm time2
+.Op Ar stratum
+.Op Ar refid
+.Xc
+This command provides a way to set certain data for a reference
+clock.
+See the source listing for further information.

+.Bl -tag -width indent
+.It Cm auth
+Enables the server to synchronize with unconfigured peers only
+if the peer has been correctly authenticated using either public key
+or private key cryptography.
+The default for this flag is enable.
+.It Cm bclient
+Enables the server to listen for a message from a broadcast or
+multicast server, as in the multicastclient command with
+default address.
+The default for this flag is disable.
+.It Cm calibrate
+Enables the calibrate feature for reference clocks.
+The default for this flag is disable.
+.It Cm kernel
+Enables the kernel time discipline, if available.
+The default for this flag is enable if support is available, otherwise disable.
+.It Cm monitor
+Enables the monitoring facility.
+See the documentation here about the
+.Cm monlist
+command or further information.
+The default for this flag is enable.
+.It Cm ntp
+Enables time and frequency discipline.
+In effect, this switch opens and closes the feedback loop,
+which is useful for testing.
+The default for this flag is enable.
+.It Cm pps
+Enables the pulse\-per\-second (PPS) signal when frequency
+and time is disciplined by the precision time kernel modifications.
+See the
+.Qq A Kernel Model for Precision Timekeeping
+(available as part of the HTML documentation
+provided in
+.Pa /usr/share/doc/ntp )
+page for further information.
+The default for this flag is disable.
+.It Cm stats
+Enables the statistics facility.
+See the
+.Sx Monitoring Options
+section of
+.Xr ntp.conf 5
+for further information.
+The default for this flag is disable.
+.El
+.It Xo Ic restrict Ar address Ar mask

+.Xc
+This command operates in the same way as the
+.Ic restrict
+configuration file commands of
+.Xr ntpd 1ntpdmdoc .
+.It Xo Ic unrestrict Ar address Ar mask
+.Ar flag Oo Ar ... Oc
+.Xc
+Unrestrict the matching entry from the restrict list.
+.It Xo Ic delrestrict Ar address Ar mask
+.Op Cm ntpport
+.Xc
+Delete the matching entry from the restrict list.
+.It Ic readkeys
+Causes the current set of authentication keys to be purged and
+a new set to be obtained by rereading the keys file (which must
+have been specified in the
+.Xr ntpd 1ntpdmdoc
+configuration file).
+This
+allows encryption keys to be changed without restarting the
+server.
+.It Ic trustedkey Ar keyid Oo Ar ... Oc
+.It Ic untrustedkey Ar keyid Oo Ar ... Oc
+These commands operate in the same way as the
+.Ic trustedkey
+and
+.Ic untrustedkey
+configuration file
+commands of
+.Xr ntpd 1ntpdmdoc .
+.It Ic authinfo
+Returns information concerning the authentication module,
+including known keys and counts of encryptions and decryptions
+which have been done.
+.It Ic traps
+Display the traps set in the server.
+See the source listing for
+further information.
+.It Xo Ic addtrap Ar address

+.Op Ar interface
+.Xc
+Set a trap for asynchronous messages.
+See the source listing

+The

+utility is a crude hack.
+Much of the information it shows is
+deadly boring and could only be loved by its implementer.
+The
+program was designed so that new (and temporary) features were easy
+to hack in, at great expense to the program's ease of use.
+Despite
+this, the program is occasionally useful.

+ * REQ_LEN_NOMAC + 4 + 16 with the auth bit enabled.  When using a

+<p>This document describes the use of the NTP Project's <code>ntpdc</code> program,
+that can be used to query a Network Time Protocol (NTP) server and
+display the time offset of the system clock relative to the server
+clock.  Run as root, it can correct the system clock to this offset as
+well.  It can be run as an interactive command or from a cron job.
+
+  <p>This document applies to version 4.2.7p482 of <code>ntpdc</code>.
+
+  <p>The program implements the SNTP protocol as defined by RFC 5905, the NTPv4
+IETF specification.

+
+<p>By default, <code>ntpdc</code> writes the local data and time (i.e., not UTC) to the
+standard output in the format:
+
+<pre class="example">     1996-10-15 20:17:25.123 (+0800) +4.567 +/- 0.089 secs
+</pre>
+  <p>where
+YYYY-MM-DD HH:MM:SS.SUBSEC is the local date and time,
+(+0800) is the local timezone adjustment (so we would add 8 hours and 0 minutes to convert the reported local time to UTC),
+and
+the +4.567 +/- 0.089 secs indicates the time offset and
+error bound of the system clock relative to the server clock.

+  <p><code>ntpdc</code>

+Please use
+<code>ntpq(1ntpqmdoc)</code> instead - it can do everything
+<code>ntpdc</code>

+
+  <p><code>ntpdc</code>
+is a utility program used to query
+<code>ntpd(1ntpdmdoc)</code>
+about its
+current state and to request changes in that state. 
+It uses NTP mode 7 control message formats described in the source code. 
+The program may
+be run either in interactive mode or controlled using command line
+arguments. 
+Extensive state and statistics information is available
+through the
+<code>ntpdc</code>
+interface. 
+In addition, nearly all the
+configuration options which can be specified at startup using
+ntpd's configuration file may also be specified at run time using
+<code>ntpdc</code>

+
+<p>Any option that is not marked as <i>not presettable</i> may be preset by
+loading values from configuration ("rc" or "ini") files, and values from environment variables named <code>NTPDC</code> and <code>NTPDC_&lt;OPTION_NAME&gt;</code>.  <code>&lt;OPTION_NAME&gt;</code> must be one of
+the options listed above in upper case and segmented with underscores. 
+The <code>NTPDC</code> variable will be tokenized and parsed like
+the command line.  The remaining variables are tested for existence and their
+values are treated like option arguments.
+
+<p class="noindent"><code>libopts</code> will search in 2 places for configuration files:
+     <ul>
+<li>$HOME
+<li>$PWD
+</ul>
+  The environment variables <code>HOME</code>, and <code>PWD</code>
+are expanded and replaced when <span class="file">ntpdc</span> runs. 
+For any of these that are plain files, they are simply processed. 
+For any that are directories, then a file named <span class="file">.ntprc</span> is searched for
+within that directory and processed.
+
+  <p>Configuration files may be in a wide variety of formats. 
+The basic format is an option name followed by a value (argument) on the
+same line.  Values may be separated from the option name with a colon,
+equal sign or simply white space.  Values may be continued across multiple
+lines by escaping the newline with a backslash.
+
+  <p>Multiple programs may also share the same initialization file. 
+Common options are collected at the top, followed by program specific
+segments.  The segments are separated by lines like:
+<pre class="example">    [NTPDC]
+</pre>
+  <p class="noindent">or by
+<pre class="example">    &lt;?program ntpdc&gt;
+</pre>
+  <p class="noindent">Do not mix these styles within one configuration file.
+
+  <p>Compound values and carefully constructed string values may also be
+specified using XML syntax:
+<pre class="example">    &lt;option-name&gt;
+       &lt;sub-opt&gt;...&amp;lt;...&amp;gt;...&lt;/sub-opt&gt;
+    &lt;/option-name&gt;
+</pre>
+  <p class="noindent">yielding an <code>option-name.sub-opt</code> string value of
+<pre class="example">    "...&lt;...&gt;..."
+</pre>
+  <p><code>AutoOpts</code> does not track suboptions.  You simply note that it is a
+hierarchicly valued option.  <code>AutoOpts</code> does provide a means for searching
+the associated name/value pair list (see: optionFindValue).
+
+  <p>The command line options relating to configuration and/or usage help are:
+
+<h5 class="subsubheading">version (-)</h5>
+
+<p>Print the program version to standard out, optionally with licensing
+information, then exit 0.  The optional argument specifies how much licensing
+detail to provide.  The default is to print just the version.  The licensing infomation may be selected with an option argument.

+<h3 class="section">Usage</h3>
+
+<p>The simplest use of this program is as an unprivileged command to
+check the current time, offset, and error in the local clock. 
+For example:
+
+<pre class="example">    ntpdc ntpserver.somewhere
+</pre>
+  <p>With suitable privilege, it can be run as a command or in a
+<code>cron</code> job to reset the local clock from a reliable server, like
+the <code>ntpdate</code> and <code>rdate</code> commands. 
+For example:
+
+<pre class="example">    ntpdc -a ntpserver.somewhere
+</pre>

+\f\*[B-Font]ntpdc\fP
+is deprecated.
+Please use
+\fCntpq\fR(@NTPQ_MS@)\f[] instead \- it can do everything

+\f\*[B-Font]ntpdc\fP
+is a utility program used to query
+\fCntpd\fR(@NTPD_MS@)\f[]
+about its
+current state and to request changes in that state.
+It uses NTP mode 7 control message formats described in the source code.
+The program may
+be run either in interactive mode or controlled using command line
+arguments.
+Extensive state and statistics information is available
+through the
+\f\*[B-Font]ntpdc\fP
+interface.
+In addition, nearly all the
+configuration options which can be specified at startup using
+ntpd's configuration file may also be specified at run time using
+\f\*[B-Font]ntpdc\fP.

+is searched for within those directories.
+.SH USAGE
+If one or more request options are included on the command line
+when
+\f\*[B-Font]ntpdc\fP
+is executed, each of the requests will be sent
+to the NTP servers running on each of the hosts given as command
+line arguments, or on localhost by default.
+If no request options
+are given,
+\f\*[B-Font]ntpdc\fP
+will attempt to read commands from the
+standard input and execute these on the NTP server running on the
+first host given on the command line, again defaulting to localhost
+when no other host is specified.
+The
+\f\*[B-Font]ntpdc\fP
+utility will prompt for
+commands if the standard input is a terminal device.
+.sp \n(Ppu
+.ne 2
+
+The
+\f\*[B-Font]ntpdc\fP
+utility uses NTP mode 7 packets to communicate with the
+NTP server, and hence can be used to query any compatible server on
+the network which permits it.
+Note that since NTP is a UDP protocol
+this communication will be somewhat unreliable, especially over
+large distances in terms of network topology.
+The
+\f\*[B-Font]ntpdc\fP
+utility makes
+no attempt to retransmit requests, and will time requests out if
+the remote host is not heard from within a suitable timeout
+time.
+.sp \n(Ppu
+.ne 2
+
+The operation of
+\f\*[B-Font]ntpdc\fP
+are specific to the particular
+implementation of the
+\fCntpd\fR(@NTPD_MS@)\f[]
+daemon and can be expected to
+work only with this and maybe some previous versions of the daemon.
+Requests from a remote
+\f\*[B-Font]ntpdc\fP
+utility which affect the
+state of the local server must be authenticated, which requires
+both the remote program and local server share a common key and key
+identifier.
+.sp \n(Ppu
+.ne 2
+
+Note that in contexts where a host name is expected, a
+\f\*[B-Font]\-4\f[]
+qualifier preceding the host name forces DNS resolution to the IPv4 namespace,
+while a
+\f\*[B-Font]\-6\f[]
+qualifier forces DNS resolution to the IPv6 namespace.
+Specifying a command line option other than
+\f\*[B-Font]\-i\f[]
+or
+\f\*[B-Font]\-n\f[]
+will cause the specified query (queries) to be sent to
+the indicated host(s) immediately.
+Otherwise,
+\f\*[B-Font]ntpdc\fP
+will
+attempt to read interactive format commands from the standard
+input.
+.SS "Interactive Commands"
+Interactive format commands consist of a keyword followed by zero
+to four arguments.
+Only enough characters of the full keyword to
+uniquely identify the command need be typed.
+The output of a
+command is normally sent to the standard output, but optionally the
+output of individual commands may be sent to a file by appending a
+\[oq]\&>\[cq],
+followed by a file name, to the command line.
+.sp \n(Ppu
+.ne 2
+
+A number of interactive format commands are executed entirely
+within the
+\f\*[B-Font]ntpdc\fP
+utility itself and do not result in NTP
+mode 7 requests being sent to a server.
+These are described
+following.

+.TP 7
+.NOP \f\*[B-Font]delay\f[] \f\*[I-Font]milliseconds\f[]

+.TP 7
+.NOP \f\*[B-Font]keyid\f[] \f\*[I-Font]keyid\f[]
+This command allows the specification of a key number to be

+successful.
+.TP 7
+.NOP \f\*[B-Font]timeout\f[] \f\*[I-Font]milliseconds\f[]
+Specify a timeout period for responses to server queries.
+The
+default is about 8000 milliseconds.
+Note that since
+\f\*[B-Font]ntpdc\fP
+retries each query once after a timeout, the total waiting time for
+a timeout will be twice the timeout value set.

+.SS "Runtime Configuration Requests"
+All requests which cause state changes in the server are
+authenticated by the server using a configured NTP key (the
+facility can also be disabled by the server by not configuring a
+key).
+The key number and the corresponding key must also be made
+known to
+\f\*[B-Font]ntpdc\fP.
+This can be done using the
+\f\*[B-Font]keyid\f[]
+and
+\f\*[B-Font]passwd\f[]
+commands, the latter of which will prompt at the terminal for a
+password to use as the encryption key.
+You will also be prompted
+automatically for both the key number and password the first time a
+command which would result in an authenticated request to the
+server is given.
+Authentication not only provides verification that
+the requester has permission to make such changes, but also gives
+an extra degree of protection again transmission errors.
+.sp \n(Ppu
+.ne 2
+
+Authenticated requests always include a timestamp in the packet
+data, which is included in the computation of the authentication
+code.
+This timestamp is compared by the server to its receive time
+stamp.
+If they differ by more than a small amount the request is
+rejected.
+This is done for two reasons.
+First, it makes simple
+replay attacks on the server, by someone who might be able to
+overhear traffic on your LAN, much more difficult.
+Second, it makes
+it more difficult to request configuration changes to your server
+from topologically remote hosts.
+While the reconfiguration facility
+will work well with a server on the local host, and may work
+adequately between time-synchronized hosts on the same LAN, it will
+work very poorly for more distant hosts.
+As such, if reasonable
+passwords are chosen, care is taken in the distribution and
+protection of keys and appropriate source address restrictions are
+applied, the run time reconfiguration facility should provide an
+adequate level of security.

+[ host ...]
+.Pp
+.Sh DESCRIPTION
+.Nm
+is deprecated.
+Please use
+.Xr ntpq @NTPQ_MS@ instead \- it can do everything
+.Nm
+used to do, and it does so using a much more sane interface.
+.Pp
+.Nm
+is a utility program used to query
+.Xr ntpd @NTPD_MS@
+about its
+current state and to request changes in that state.
+It uses NTP mode 7 control message formats described in the source code.
+The program may
+be run either in interactive mode or controlled using command line
+arguments.
+Extensive state and statistics information is available
+through the
+.Nm
+interface.
+In addition, nearly all the
+configuration options which can be specified at startup using
+ntpd's configuration file may also be specified at run time using
+.Nm .

+print the full copyright notice.
+.El
+.Sh "OPTION PRESETS"
+Any option that is not marked as \fInot presettable\fP may be preset
+by loading values from configuration ("RC" or ".INI") file(s) and values from
+environment variables named:
+.nf
+  \fBNTPDC_<option\-name>\fP or \fBNTPDC\fP
+.fi
+.ad
+The environmental presets take precedence (are processed later than)
+the configuration files.
+The \fIhomerc\fP files are "\fI$HOME\fP", and "\fI.\fP".
+If any of these are directories, then the file \fI.ntprc\fP
+is searched for within those directories.
+.Sh USAGE
+If one or more request options are included on the command line
+when
+.Nm
+is executed, each of the requests will be sent
+to the NTP servers running on each of the hosts given as command
+line arguments, or on localhost by default.
+If no request options
+are given,
+.Nm
+will attempt to read commands from the
+standard input and execute these on the NTP server running on the
+first host given on the command line, again defaulting to localhost
+when no other host is specified.
+The
+.Nm
+utility will prompt for
+commands if the standard input is a terminal device.
+.Pp
+The
+.Nm
+utility uses NTP mode 7 packets to communicate with the
+NTP server, and hence can be used to query any compatible server on
+the network which permits it.
+Note that since NTP is a UDP protocol
+this communication will be somewhat unreliable, especially over
+large distances in terms of network topology.
+The
+.Nm
+utility makes
+no attempt to retransmit requests, and will time requests out if
+the remote host is not heard from within a suitable timeout
+time.
+.Pp
+The operation of
+.Nm
+are specific to the particular
+implementation of the
+.Xr ntpd @NTPD_MS@
+daemon and can be expected to
+work only with this and maybe some previous versions of the daemon.
+Requests from a remote
+.Nm
+utility which affect the
+state of the local server must be authenticated, which requires
+both the remote program and local server share a common key and key
+identifier.
+.Pp
+Note that in contexts where a host name is expected, a
+.Fl 4
+qualifier preceding the host name forces DNS resolution to the IPv4 namespace,
+while a
+.Fl 6
+qualifier forces DNS resolution to the IPv6 namespace.
+Specifying a command line option other than
+.Fl i
+or
+.Fl n
+will cause the specified query (queries) to be sent to
+the indicated host(s) immediately.
+Otherwise,
+.Nm
+will
+attempt to read interactive format commands from the standard
+input.
+.Ss "Interactive Commands"
+Interactive format commands consist of a keyword followed by zero
+to four arguments.
+Only enough characters of the full keyword to
+uniquely identify the command need be typed.
+The output of a
+command is normally sent to the standard output, but optionally the
+output of individual commands may be sent to a file by appending a
+.Ql \&> ,
+followed by a file name, to the command line.
+.Pp
+A number of interactive format commands are executed entirely
+within the
+.Nm
+utility itself and do not result in NTP
+mode 7 requests being sent to a server.
+These are described
+following.
+.Bl -tag -width indent
+.It Ic \&? Ar command_keyword
+.It Ic help Ar command_keyword
+A
+.Sq Ic \&?
+will print a list of all the command
+keywords known to this incarnation of
+.Nm .
+A
+.Sq Ic \&?
+followed by a command keyword will print function and usage
+information about the command.
+This command is probably a better
+source of information about
+.Xr ntpq @NTPQ_MS@
+than this manual
+page.
+.It Ic delay Ar milliseconds
+Specify a time interval to be added to timestamps included in
+requests which require authentication.
+This is used to enable
+(unreliable) server reconfiguration over long delay network paths
+or between machines whose clocks are unsynchronized.
+Actually the
+server does not now require timestamps in authenticated requests,
+so this command may be obsolete.
+.It Ic host Ar hostname
+Set the host to which future queries will be sent.
+Hostname may
+be either a host name or a numeric address.
+.It Ic hostnames Op Cm yes | Cm no
+If
+.Cm yes
+is specified, host names are printed in
+information displays.
+If
+.Cm no
+is specified, numeric
+addresses are printed instead.
+The default is
+.Cm yes ,
+unless
+modified using the command line
+.Fl n
+switch.
+.It Ic keyid Ar keyid
+This command allows the specification of a key number to be
+used to authenticate configuration requests.
+This must correspond
+to a key number the server has been configured to use for this
+purpose.
+.It Ic quit
+Exit
+.Nm .
+.It Ic passwd
+This command prompts you to type in a password (which will not
+be echoed) which will be used to authenticate configuration
+requests.
+The password must correspond to the key configured for
+use by the NTP server for this purpose if such requests are to be
+successful.
+.It Ic timeout Ar milliseconds
+Specify a timeout period for responses to server queries.
+The
+default is about 8000 milliseconds.
+Note that since
+.Nm
+retries each query once after a timeout, the total waiting time for
+a timeout will be twice the timeout value set.
+.El
+.Ss "Control Message Commands"
+Query commands result in NTP mode 7 packets containing requests for
+information being sent to the server.
+These are read\-only commands
+in that they make no modification of the server configuration
+state.
+.Bl -tag -width indent
+.It Ic listpeers
+Obtains and prints a brief list of the peers for which the
+server is maintaining state.
+These should include all configured
+peer associations as well as those peers whose stratum is such that
+they are considered by the server to be possible future
+synchronization candidates.
+.It Ic peers
+Obtains a list of peers for which the server is maintaining
+state, along with a summary of that state.
+Summary information
+includes the address of the remote peer, the local interface
+address (0.0.0.0 if a local address has yet to be determined), the
+stratum of the remote peer (a stratum of 16 indicates the remote
+peer is unsynchronized), the polling interval, in seconds, the
+reachability register, in octal, and the current estimated delay,
+offset and dispersion of the peer, all in seconds.
+.Pp
+The character in the left margin indicates the mode this peer
+entry is operating in.
+A
+.Ql \&+
+denotes symmetric active, a
+.Ql \&\-
+indicates symmetric passive, a
+.Ql \&=
+means the
+remote server is being polled in client mode, a
+.Ql \&^
+indicates that the server is broadcasting to this address, a
+.Ql \&~
+denotes that the remote peer is sending broadcasts and a
+.Ql \&~
+denotes that the remote peer is sending broadcasts and a
+.Ql \&*
+marks the peer the server is currently synchronizing
+to.
+.Pp
+The contents of the host field may be one of four forms.
+It may
+be a host name, an IP address, a reference clock implementation
+name with its parameter or
+.Fn REFCLK "implementation_number" "parameter" .
+On
+.Ic hostnames
+.Cm no
+only IP\-addresses
+will be displayed.
+.It Ic dmpeers
+A slightly different peer summary list.
+Identical to the output
+of the
+.Ic peers
+command, except for the character in the
+leftmost column.
+Characters only appear beside peers which were
+included in the final stage of the clock selection algorithm.
+A
+.Ql \&.
+indicates that this peer was cast off in the falseticker
+detection, while a
+.Ql \&+
+indicates that the peer made it
+through.
+A
+.Ql \&*
+denotes the peer the server is currently
+synchronizing with.
+.It Ic showpeer Ar peer_address Oo Ar ... Oc
+Shows a detailed display of the current peer variables for one
+or more peers.
+Most of these values are described in the NTP
+Version 2 specification.
+.It Ic pstats Ar peer_address Oo Ar ... Oc
+Show per\-peer statistic counters associated with the specified
+peer(s).
+.It Ic clockstat Ar clock_peer_address Oo Ar ... Oc
+Obtain and print information concerning a peer clock.
+The
+values obtained provide information on the setting of fudge factors
+and other clock performance information.
+.It Ic kerninfo
+Obtain and print kernel phase\-lock loop operating parameters.
+This information is available only if the kernel has been specially
+modified for a precision timekeeping function.
+.It Ic loopinfo Op Cm oneline | Cm multiline
+Print the values of selected loop filter variables.
+The loop
+filter is the part of NTP which deals with adjusting the local
+system clock.
+The
+.Sq offset
+is the last offset given to the
+loop filter by the packet processing code.
+The
+.Sq frequency
+is the frequency error of the local clock in parts\-per\-million
+(ppm).
+The
+.Sq time_const
+controls the stiffness of the
+phase\-lock loop and thus the speed at which it can adapt to
+oscillator drift.
+The
+.Sq watchdog timer
+value is the number
+of seconds which have elapsed since the last sample offset was
+given to the loop filter.
+The
+.Cm oneline
+and
+.Cm multiline
+options specify the format in which this
+information is to be printed, with
+.Cm multiline
+as the
+default.
+.It Ic sysinfo
+Print a variety of system state variables, i.e., state related
+to the local server.
+All except the last four lines are described
+in the NTP Version 3 specification, RFC\-1305.
+.Pp
+The
+.Sq system flags
+show various system flags, some of
+which can be set and cleared by the
+.Ic enable
+and
+.Ic disable
+configuration commands, respectively.
+These are
+the
+.Cm auth ,
+.Cm bclient ,
+.Cm monitor ,
+.Cm pll ,
+.Cm pps
+and
+.Cm stats
+flags.
+See the
+.Xr ntpd @NTPD_MS@
+documentation for the meaning of these flags.
+There
+are two additional flags which are read only, the
+.Cm kernel_pll
+and
+.Cm kernel_pps .
+These flags indicate
+the synchronization status when the precision time kernel
+modifications are in use.
+The
+.Sq kernel_pll
+indicates that
+the local clock is being disciplined by the kernel, while the
+.Sq kernel_pps
+indicates the kernel discipline is provided by the PPS
+signal.
+.Pp
+The
+.Sq stability
+is the residual frequency error remaining
+after the system frequency correction is applied and is intended for
+maintenance and debugging.
+In most architectures, this value will
+initially decrease from as high as 500 ppm to a nominal value in
+the range .01 to 0.1 ppm.
+If it remains high for some time after
+starting the daemon, something may be wrong with the local clock,
+or the value of the kernel variable
+.Va kern.clockrate.tick
+may be
+incorrect.
+.Pp
+The
+.Sq broadcastdelay
+shows the default broadcast delay,
+as set by the
+.Ic broadcastdelay
+configuration command.
+.Pp
+The
+.Sq authdelay
+shows the default authentication delay,
+as set by the
+.Ic authdelay
+configuration command.
+.It Ic sysstats
+Print statistics counters maintained in the protocol
+module.
+.It Ic memstats
+Print statistics counters related to memory allocation
+code.
+.It Ic iostats
+Print statistics counters maintained in the input\-output
+module.
+.It Ic timerstats
+Print statistics counters maintained in the timer/event queue
+support code.
+.It Ic reslist
+Obtain and print the server's restriction list.
+This list is
+(usually) printed in sorted order and may help to understand how
+the restrictions are applied.
+.It Ic monlist Op Ar version
+Obtain and print traffic counts collected and maintained by the
+monitor facility.
+The version number should not normally need to be
+specified.
+.It Ic clkbug Ar clock_peer_address Oo Ar ... Oc
+Obtain debugging information for a reference clock driver.
+This
+information is provided only by some clock drivers and is mostly
+undecodable without a copy of the driver source in hand.
+.El
+.Ss "Runtime Configuration Requests"
+All requests which cause state changes in the server are
+authenticated by the server using a configured NTP key (the
+facility can also be disabled by the server by not configuring a
+key).
+The key number and the corresponding key must also be made
+known to
+.Nm .
+This can be done using the
+.Ic keyid
+and
+.Ic passwd
+commands, the latter of which will prompt at the terminal for a
+password to use as the encryption key.
+You will also be prompted
+automatically for both the key number and password the first time a
+command which would result in an authenticated request to the
+server is given.
+Authentication not only provides verification that
+the requester has permission to make such changes, but also gives
+an extra degree of protection again transmission errors.
+.Pp
+Authenticated requests always include a timestamp in the packet
+data, which is included in the computation of the authentication
+code.
+This timestamp is compared by the server to its receive time
+stamp.
+If they differ by more than a small amount the request is
+rejected.
+This is done for two reasons.
+First, it makes simple
+replay attacks on the server, by someone who might be able to
+overhear traffic on your LAN, much more difficult.
+Second, it makes
+it more difficult to request configuration changes to your server
+from topologically remote hosts.
+While the reconfiguration facility
+will work well with a server on the local host, and may work
+adequately between time\-synchronized hosts on the same LAN, it will
+work very poorly for more distant hosts.
+As such, if reasonable
+passwords are chosen, care is taken in the distribution and
+protection of keys and appropriate source address restrictions are
+applied, the run time reconfiguration facility should provide an
+adequate level of security.
+.Pp
+The following commands all make authenticated requests.
+.Bl -tag -width indent
+.It Xo Ic addpeer Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Add a configured peer association at the given address and
+operating in symmetric active mode.
+Note that an existing
+association with the same peer may be deleted when this command is
+executed, or may simply be converted to conform to the new
+configuration, as appropriate.
+If the optional
+.Ar keyid
+is a
+nonzero integer, all outgoing packets to the remote server will
+have an authentication field attached encrypted with this key.
+If
+the value is 0 (or not given) no authentication will be done.
+The
+.Ar version
+can be 1, 2 or 3 and defaults to 3.
+The
+.Cm prefer
+keyword indicates a preferred peer (and thus will
+be used primarily for clock synchronisation if possible).
+The
+preferred peer also determines the validity of the PPS signal \- if
+the preferred peer is suitable for synchronisation so is the PPS
+signal.
+.It Xo Ic addserver Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Identical to the addpeer command, except that the operating
+mode is client.
+.It Xo Ic broadcast Ar peer_address
+.Op Ar keyid
+.Op Ar version
+.Op Cm prefer
+.Xc
+Identical to the addpeer command, except that the operating
+mode is broadcast.
+In this case a valid key identifier and key are
+required.
+The
+.Ar peer_address
+parameter can be the broadcast
+address of the local network or a multicast group address assigned
+to NTP.
+If a multicast address, a multicast\-capable kernel is
+required.
+.It Ic unconfig Ar peer_address Oo Ar ... Oc
+This command causes the configured bit to be removed from the
+specified peer(s).
+In many cases this will cause the peer
+association to be deleted.
+When appropriate, however, the
+association may persist in an unconfigured mode if the remote peer
+is willing to continue on in this fashion.

+@top ntpdc: NTPD Control User Manual
+
+This document describes the use of the NTP Project's @code{ntpdc} program,
+that can be used to query a Network Time Protocol (NTP) server and
+display the time offset of the system clock relative to the server
+clock.  Run as root, it can correct the system clock to this offset as
+well.  It can be run as an interactive command or from a cron job.
+
+This document applies to version @value{VERSION} of @code{ntpdc}.
+
+The program implements the SNTP protocol as defined by RFC 5905, the NTPv4
+IETF specification.

+
+@node ntpdc Description
+@comment  node-name,  next,  previous,  up
+@section Description
+
+By default, @code{ntpdc} writes the local data and time (i.e., not UTC) to the
+standard output in the format:
+
+@example
+1996-10-15 20:17:25.123 (+0800) +4.567 +/- 0.089 secs
+@end example
+
+where
+YYYY-MM-DD HH:MM:SS.SUBSEC is the local date and time,
+(+0800) is the local timezone adjustment (so we would add 8 hours and 0 minutes to convert the reported local time to UTC),
+and
+the +4.567 +/- 0.089 secs indicates the time offset and
+error bound of the system clock relative to the server clock.
+
+@include invoke-ntpdc.texi
+
+@node Usage
+@comment  node-name,  next,  previous,  up
+@section Usage
+
+The simplest use of this program is as an unprivileged command to
+check the current time, offset, and error in the local clock.
+For example:
+
+@example
+ntpdc ntpserver.somewhere
+@end example
+
+With suitable privilege, it can be run as a command or in a
+@code{cron} job to reset the local clock from a reliable server, like
+the @code{ntpdate} and @code{rdate} commands.
+For example:
+
+@example
+ntpdc -a ntpserver.somewhere
+@end example
