## NAME
     **ntpq** — standard NTP query program

## SYNOPSIS
     **ntpq** [**-flags**] [**-flag** [_value_]] [**--option-name**[[=| ]_value_]] [ host ...]

## DESCRIPTION
     The **ntpq** utility program is used to query NTP servers to monitor NTP operations and perfor‐
     mance, requesting information about current state and/or changes in that state.  The program
     may be run either in interactive mode or controlled using command line arguments.  Requests to
     read and write arbitrary variables can be assembled, with raw and pretty-printed output options
     being available.  The **ntpq** utility can also obtain and print a list of peers in a common format
     by sending multiple queries to the server.

     If one or more request options is included on the command line when **ntpq** 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, **ntpq** 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 **ntpq** utility will prompt for commands if the standard input is a terminal device.

     **ntpq** uses NTP mode 6 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 **ntpq** utility makes one attempt to retransmit requests, and will time re‐
     quests out if the remote host is not heard from within a suitable timeout time.

     Note that in contexts where a host name is expected, a **-4** qualifier preceding the host name
     forces resolution to the IPv4 namespace, while a **-6** qualifier forces resolution to the IPv6
     namespace.  For examples and usage, see the “NTP Debugging Techniques” page.

     Specifying a command line option other than **-i** or **-n** will cause the specified query (queries)
     to be sent to the indicated host(s) immediately.  Otherwise, **ntpq** will attempt to read interac‐
     tive format commands from the standard input.

### Internal 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.

     A number of interactive format commands are executed entirely within the **ntpq** utility itself
     and do not result in NTP requests being sent to a server.  These are described following.
           ? [_command_]
           **help** [_command_]  A ‘?’ by itself will print a list of all the commands known to **ntpq**.  A
                           ‘?’ followed by a command name will print function and usage information
                           about the command.
           **addvars** _name_[=_value_][,...]
           **rmvars** _name_[,...]
           **clearvars**
           **showvars**        The arguments to this command consist of a list of items of the form
                           _name_[=_value_], where the =_value_ is ignored, and can be omitted, in re‐
                           quests to the server to read variables.  The **ntpq** utility maintains an
                           internal list in which data to be included in messages can be assembled,
                           and displayed or set using the **readlist** and **writelist** commands described
                           below.  The **addvars** command allows variables and their optional values to
                           be added to the list.  If more than one variable is to be added, the list
                           should be comma-separated and not contain white space.  The **rmvars** com‐
                           mand can be used to remove individual variables from the list, while the
                           **clearvars** command removes all variables from the list.  The **showvars** com‐
                           mand displays the current list of optional variables.
           **authenticate** [**yes**|**no**]
                           Normally **ntpq** does not authenticate requests unless they are write re‐
                           quests.  The command **authenticate** **yes** causes **ntpq** to send authentication
                           with all requests it makes.  Authenticated requests causes some servers
                           to handle requests slightly differently.  The command **authenticate** causes
                           **ntpq** to display whether or not it is currently authenticating requests.
           **cooked**          Causes output from query commands to be "cooked", so that variables which
                           are recognized by **ntpq** will have their values reformatted for human con‐
                           sumption.  Variables which **ntpq** could not decode completely are marked
                           with a trailing ‘?’.
           **debug** [**more**|**less**|**off**]
                           With no argument, displays the current debug level.  Otherwise, the de‐
                           bugging level is changed as indicated.
           **delay** [_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.
                           Without any arguments, displays the current delay.
           **drefid** [**hash**|**ipv4**]
                           Display refids as IPv4 or hash.  Without any arguments, displays whether
                           refids are shown as IPv4 addresses or hashes.
           **exit**            Exit **ntpq**.
           **host** [_name_]     Set the host to which future queries will be sent.  The _name_ may be ei‐
                           ther a host name or a numeric address.  Without any arguments, displays
                           the current host.
           **hostnames** [**yes**|**no**]
                           If **yes** is specified, host names are printed in information displays.  If
                           **no** is specified, numeric addresses are printed instead.  The default is
                           **yes**, unless modified using the command line **-n** switch.  Without any argu‐
                           ments, displays whether host names or numeric addresses are shown.
           **keyid** [_keyid_]   This command allows the specification of a key number to be used to au‐
                           thenticate configuration requests.  This must correspond to the
                           **controlkey** key number the server has been configured to use for this pur‐
                           pose.  Without any arguments, displays the current _keyid_.
           **keytype** [_digest_]
                           Specify the digest algorithm to use for authenticating requests, with de‐
                           fault **MD5**.  If **ntpq** was built with OpenSSL support, and OpenSSL is in‐
                           stalled, _digest_ can be any message digest algorithm supported by OpenSSL.
                           If no argument is given, the current **keytype** _digest_ algorithm used is
                           displayed.
           **ntpversion** [**1**|**2**|**3**|**4**]
                           Sets the NTP version number which **ntpq** claims in packets.  Defaults to 3,
                           and note that mode 6 control messages (and modes, for that matter) didn't
                           exist in NTP version 1.  There appear to be no servers left which demand
                           version 1.  With no argument, displays the current NTP version that will
                           be used when communicating with servers.
           **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.
           **poll** [_n_] [**verbose**]
                           Poll an NTP server in client mode _n_ times.  Poll not implemented yet.
           **quit**            Exit **ntpq**.
           **raw**             Causes all output from query commands is printed as received from the re‐
                           mote server.  The only formating/interpretation done on the data is to
                           transform nonascii data into a printable (but barely understandable)
                           form.
           **timeout** [_milliseconds_]
                           Specify a timeout period for responses to server queries.  The default is
                           about 5000 milliseconds.  Without any arguments, displays the current
                           timeout period.  Note that since **ntpq** retries each query once after a
                           timeout, the total waiting time for a timeout will be twice the timeout
                           value set.
           **version**         Display the version of the **ntpq** program.

### Control Message Commands
     Association ids are used to identify system, peer and clock variables.  System variables are
     assigned an association id of zero and system name space, while each association is assigned a
     nonzero association id and peer namespace.  Most control commands send a single message to the
     server and expect a single response message.  The exceptions are the **peers** command, which sends
     a series of messages, and the **mreadlist** and **mreadvar** commands, which iterate over a range of
     associations.
           **apeers**     Display a list of peers in the form:
                            [tally]remote refid assid st t when pool reach delay offset jitter
                      where the output is just like the **peers** command except that the **refid** is dis‐
                      played in hex format and the association number is also displayed.
           **associations**
                      Display a list of mobilized associations in the form:
                            ind assid status conf reach auth condition last_event cnt

                            **Variable**    **Description**
                            **ind**         index on this list
                            **assid**       association id
                            **status**      peer status word
                            **conf**        **yes**: persistent, **no**: ephemeral
                            **reach**       **yes**: reachable, **no**: unreachable
                            **auth**        **ok**, **yes**, **bad** and **none**
                            **condition**   selection status (see the **select** field of the peer status
                                                                                        word)
                            **last**___**event**  event report (see the **event** field of the peer status word)
                            **cnt**         event count (see the **count** field of the peer status word)
           **authinfo**   Display the authentication statistics counters: time since reset, stored keys,
                      free keys, key lookups, keys not found, uncached keys, expired keys, encryp‐
                      tions, decryptions.
           **clocklist** [_associd_]
           **cl** [_associd_]
                      Display all clock variables in the variable list for those associations sup‐
                      porting a reference clock.
           **clockvar** [_associd_] [_name_[=_value_]][,...]
           **cv** [_associd_] [_name_[=_value_]][,...]
                      Display a list of clock variables for those associations supporting a refer‐
                      ence clock.
           **:config** _configuration_ _command_ _line_
                      Send the remainder of the command line, including whitespace, to the server as
                      a run-time configuration command in the same format as a line in the configu‐
                      ration file.  This command is experimental until further notice and clarifica‐
                      tion.  Authentication is of course required.
           **config-from-file** _filename_
                      Send each line of _filename_ to the server as run-time configuration commands in
                      the same format as lines in the configuration file.  This command is experi‐
                      mental until further notice and clarification.  Authentication is required.
           **ifstats**    Display status and statistics counters for each local network interface ad‐
                      dress: interface number, interface name and address or broadcast, drop, flag,
                      ttl, mc, received, sent, send failed, peers, uptime.  Authentication is re‐
                      quired.
           **iostats**    Display network and reference clock I/O statistics: time since reset, receive
                      buffers, free receive buffers, used receive buffers, low water refills,
                      dropped packets, ignored packets, received packets, packets sent, packet send
                      failures, input wakeups, useful input wakeups.
           **kerninfo**   Display kernel loop and PPS statistics: associd, status, pll offset, pll fre‐
                      quency, maximum error, estimated error, kernel status, pll time constant, pre‐
                      cision, frequency tolerance, pps frequency, pps stability, pps jitter, cali‐
                      bration interval, calibration cycles, jitter exceeded, stability exceeded,
                      calibration errors.  As with other ntpq output, times are in milliseconds;
                      very small values may be shown as exponentials.  The precision value displayed
                      is in milliseconds as well, unlike the precision system variable.
           **lassociations**
                      Perform the same function as the associations command, except display mobi‐
                      lized and unmobilized associations, including all clients.
           **lopeers** [**-4**|**-6**]
                      Display a list of all peers and clients showing **dstadr** (associated with the
                      given IP version).
           **lpassociations**
                      Display the last obtained list of associations, including all clients.
           **lpeers** [**-4**|**-6**]
                      Display a list of all peers and clients (associated with the given IP ver‐
                      sion).
           **monstats**   Display monitor facility status, statistics, and limits: enabled, addresses,
                      peak addresses, maximum addresses, reclaim above count, reclaim older than,
                      kilobytes, maximum kilobytes.
           **mreadlist** _associdlo_ _associdhi_
           **mrl** _associdlo_ _associdhi_
                      Perform the same function as the **readlist** command for a range of association
                      ids.
           **mreadvar** _associdlo_ _associdhi_ [_name_][,...]
                      This range may be determined from the list displayed by any command showing
                      associations.
           **mrv** _associdlo_ _associdhi_ [_name_][,...]
                      Perform the same function as the **readvar** command for a range of association
                      ids.  This range may be determined from the list displayed by any command
                      showing associations.
           **mrulist** [**limited** | **kod** | **mincount**=_count_ | **laddr**=_localaddr_ | **sort**=[-]_sortorder_ |
                      **resany**=_hexmask_ | **resall**=_hexmask_]
                      Display traffic counts of the most recently seen source addresses collected
                      and maintained by the monitor facility.  With the exception of
                      **sort**=[-]_sortorder_, the options filter the list returned by [ntpd(8)](https://www.chedong.com/phpMan.php/man/ntpd/8/markdown).  The
                      **limited** and **kod** options return only entries representing client addresses from
                      which the last packet received triggered either discarding or a KoD response.
                      The **mincount**=_count_ option filters entries representing less than _count_ pack‐
                      ets.  The **laddr**=_localaddr_ option filters entries for packets received on any
                      local address other than _localaddr_.  **resany**=_hexmask_ and **resall**=_hexmask_ filter
                      entries containing none or less than all, respectively, of the bits in
                      _hexmask_, which must begin with **0x**.  The _sortorder_ defaults to **lstint** and may
                      be **addr**, **avgint**, **count**, **lstint**, or any of those preceded by ‘-’ to reverse the
                      sort order.  The output columns are:
                            Column     Description
                            **lstint**     Interval in seconds between the receipt of the most recent
                                       packet from this address and the completion of the retrieval
                                       of the MRU list by **ntpq**.
                            **avgint**     Average interval in s between packets from this address.
                            **rstr**       Restriction flags associated with this address.  Most are
                                       copied unchanged from the matching **restrict** command, however

                      Obtain and print the old-style list of all peers and clients showing **dstadr**
                      (associated with the given IP version), rather than the **refid**.
           **passociations**
                      Perform the same function as the **associations** command, except that it uses
                      previously stored data rather than making a new query.
           **peers**      Display a list of peers in the form:

                                       be truncated to 15 characters unless the **ntpq** **-w** option is
                                       given, in which case the full value will be displayed on the
                                       first line, and if too long, the remaining data will be dis‐
                                       played on the next line.

           **pstats** _associd_
                      Display the statistics for the peer with the given _associd_: associd, status,
                      remote host, local address, time last received, time until next send, reacha‐
                      bility change, packets sent, packets received, bad authentication, bogus ori‐
                      gin, duplicate, bad dispersion, bad reference time, candidate order.
           **readlist** [_associd_]
           **rl** [_associd_]
                      Display all system or peer variables.  If the _associd_ is omitted, it is as‐
                      sumed to be zero.
           **readvar** [_associd_ _name_[=_value_] [, ...]]
           **rv** [_associd_ _name_[=_value_] [, ...]]
                      Display the specified system or peer variables.  If _associd_ is zero, the vari‐
                      ables are from the _System_ _Variables_ name space, otherwise they are from the
                      _Peer_ _Variables_ name space.  The _associd_ is required, as the same name can oc‐
                      cur in both spaces.  If no _name_ is included, all operative variables in the
                      name space are displayed.  In this case only, if the _associd_ is omitted, it is
                      assumed to be zero.  Multiple names are specified with comma separators and
                      without whitespace.  Note that time values are represented in milliseconds and
                      frequency values in parts-per-million (PPM).  Some NTP timestamps are repre‐
                      sented in the format _YYYYMM_ _DD_ _TTTT_, where _YYYY_ is the year, _MM_ the month of
                      year, _DD_ the day of month and _TTTT_ the time of day.
           **reslist**    Display the access control (restrict) list for **ntpq**.  Authentication is re‐
                      quired.
           **saveconfig** _filename_
                      Save the current configuration, including any runtime modifications made by
                      **:config** or **config-from-file**, to the NTP server host file _filename_.  This com‐
                      mand will be rejected by the server unless _saveconfigdir_:
                      **miscopt.html#saveconfigdir** appears in the [ntpd(8)](https://www.chedong.com/phpMan.php/man/ntpd/8/markdown) configuration file.
                      _filename_ can use [date(1)](https://www.chedong.com/phpMan.php/man/date/1/markdown) format specifiers to substitute the current date and
                      time, for example,
                            **saveconfig** _ntp-%Y%m%d-%H%M%S.conf_.
                      The filename used is stored in system variable **savedconfig**.  Authentication is
                      required.
           **sysinfo**    Display system operational summary: associd, status, system peer, system peer
                      mode, leap indicator, stratum, log2 precision, root delay, root dispersion,
                      reference id, reference time, system jitter, clock jitter, clock wander,
                      broadcast delay, symm. auth. delay.
           **sysstats**   Display system uptime and packet counts maintained in the protocol module: up‐
                      time, sysstats reset, packets received, current version, older version, bad
                      length or format, authentication failed, declined, restricted, rate limited,
                      KoD responses, processed for time.
           **timerstats**
                      Display interval timer counters: time since reset, timer overruns, calls to
                      transmit.
           **writelist** _associd_
                      Set all system or peer variables included in the variable list.
           **writevar** _associd_ _name_=_value_ [, ...]
                      Set the specified variables in the variable list.  If the _associd_ is zero, the
                      variables are from the _System_ _Variables_ name space, otherwise they are from
                      the _Peer_ _Variables_ name space.  The _associd_ is required, as the same name can
                      occur in both spaces.  Authentication is required.

### Status Words and Kiss Codes
     The current state of the operating program is shown in a set of status words maintained by the
     system.  Status information is also available on a per-association basis.  These words are dis‐
     played by the **readlist** and **associations** commands both in hexadecimal and in decoded short tip
     strings.  The codes, tips and short explanations are documented on the _Event_ _Messages_ _and_
     _Status_ _Words_: **decode.html** page.  The page also includes a list of system and peer messages, the
     code for the latest of which is included in the status word.

     Information resulting from protocol machine state transitions is displayed using an informal
     set of ASCII strings called _kiss_ _codes_: **decode.html#kiss**. The original purpose was for
     kiss-o'-death (KoD) packets sent by the server to advise the client of an unusual condition.
     They are now displayed, when appropriate, in the reference identifier field in various bill‐
     boards.

### System Variables
     The following system variables appear in the **readlist** billboard.  Not all variables are dis‐
     played in some configurations.

     The jitter and wander statistics are exponentially-weighted RMS averages.  The system jitter is
     defined in the NTPv4 specification; the clock jitter statistic is computed by the clock disci‐
     pline module.

     When the NTPv4 daemon is compiled with the OpenSSL software library, additional system vari‐
     ables are displayed, including some or all of the following, depending on the particular Au‐
     tokey dance:
           Variable   Description
           **host**       Autokey host name for this host

           **xleave**     interleave delay (see _NTP_ _Interleaved_ _Modes_: **xleave.html**)
     The **bias** variable is calculated when the first broadcast packet is received after the calibra‐
     tion volley.  It represents the offset of the broadcast subgraph relative to the unicast sub‐
     graph.  The **xleave** variable appears only for the interleaved symmetric and interleaved modes.
     It represents the internal queuing, buffering and transmission delays for the preceding packet.

     When the NTPv4 daemon is compiled with the OpenSSL software library, additional peer variables
     are displayed, including the following:

## OPTIONS
### -4 --ipv4
             Force IPv4 name resolution.  This option must not appear in combination with any of the
             following options: ipv6.

             Force resolution of following host names on the command line to the IPv4 namespace.

### -6 --ipv6
             Force IPv6 name resolution.  This option must not appear in combination with any of the
             following options: ipv4.

             Force resolution of following host names on the command line to the IPv6 namespace.

### -c --command
             run a command and exit.  This option may appear an unlimited number of times.

             The following argument is interpreted as an interactive format command and is added to
             the list of commands to be executed on the specified host(s).

### -d --debug-level
             Increase debug verbosity level.  This option may appear an unlimited number of times.


### -D --set-debug-level
             Set the debug verbosity level.  This option may appear an unlimited number of times.
             This option takes an integer number as its argument.


### -i --interactive
             Force ntpq to operate in interactive mode.  This option must not appear in combination
             with any of the following options: command, peers.

             Force **ntpq** to operate in interactive mode.  Prompts will be written to the standard
             output and commands read from the standard input.

### -n --numeric
             numeric host addresses.

             Output all host addresses in dotted-quad numeric format rather than converting to the
             canonical host names.

### --old-rv
             Always output status line with readvar.

             By default, **ntpq** now suppresses the **associd=...**  line that precedes the output of **read**‐‐
             **var** (alias **rv**) when a single variable is requested, such as **ntpq** **-c** **"rv** **0** **offset"**.
             This option causes **ntpq** to include both lines of output for a single-variable **readvar**.
             Using an environment variable to preset this option in a script will enable both older
             and newer **ntpq** to behave identically in this regard.

### -p --peers
             Print a list of the peers.  This option must not appear in combination with any of the
             following options: interactive.

             Print a list of the peers known to the server as well as a summary of their state. This
             is equivalent to the 'peers' interactive command.

### -r --refid
             Set default display type for S2+ refids.  This option takes a keyword as its argument.
             The argument sets an enumeration value that can be tested by comparing them against the
             option value macro.  The available keywords are:
                 hash ipv4
                 or their numeric equivalent.

             The default _keyword_ for this option is:
                  ipv4

             Set the default display format for S2+ refids.

### -w --wide
             Display the full 'remote' value.

             Display the full value of the 'remote' value.  If this requires more than 15 charac‐
             ters, display the full value, emit a newline, and continue the data display properly
             indented on the next line.

     **-?**, **--help**
             Display usage information and exit.

     **-!**, **--more-help**
             Pass the extended usage information through a pager.

     **->** [_cfgfile_], **--save-opts** [=_cfgfile_]
             Save the option state to _cfgfile_.  The default is the _last_ configuration file listed in
             the **OPTION** **PRESETS** section, below.  The command will exit after updating the config
             file.

     **-<** _cfgfile_, **--load-opts**=_cfgfile_, **--no-load-opts**
             Load options from _cfgfile_.  The _no-load-opts_ form will disable the loading of earlier
             config/rc/ini files.  _--no-load-opts_ is handled early, out of order.

     **--version** [{_v|c|n_}]
             Output version of program and exit.  The default mode is `v', a simple version.  The
             `c' mode will print copyright information and `n' will print the full copyright notice.

## OPTION PRESETS
     Any option that is not marked as _not_ _presettable_ may be preset by loading values from configu‐
     ration ("RC" or ".INI") file(s) and values from environment variables named:
       **NTPQ**___**<option-name>** or **NTPQ**
     The environmental presets take precedence (are processed later than) the  configuration  files.
     The  _homerc_  files are "_$HOME_", and "_._".  If any of these are directories, then the file _.ntprc_
     is searched for within those directories.

## ENVIRONMENT
     See **OPTION** **PRESETS** for configuration environment variables.

## FILES
     See **OPTION** **PRESETS** for configuration files.

## EXIT STATUS
     One of the following exit values will be returned:

     0  (EXIT_SUCCESS)
             Successful program execution.

     1  (EXIT_FAILURE)
             The operation failed or the command syntax was not valid.

     66  (EX_NOINPUT)
             A specified configuration file could not be loaded.

     70  (EX_SOFTWARE)
             libopts had an internal operational error.  Please report it to auto‐
             <gen-users@lists.sourceforge.net>.  Thank you.
