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 op-
     erations and performance, requesting information about current state
     and/or changes in that state.  The program may be run either in interac-
     tive 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 com-
     mands from the standard input and execute these on the NTP server running
     on the first host given on the command line, again defaulting to local-
     host 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 re-
     quests, and will time requests 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 pre-
     ceding the host name forces resolution to the IPv4 namespace, while a -6
     qualifier forces resolution to the IPv6 namespace.  For examples and us-
     age, see the "NTP Debugging Techniques" page.

     Specifying a command line option other than -i or -n will cause the spec-
     ified query (queries) to be sent to the indicated host(s) immediately.
     Otherwise, ntpq will attempt to read interactive 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 iden-
     tify 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 com-
                           mands 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 requests to the
                           server to read variables.  The ntpq utility main-
                           tains 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 command can be used to remove
                           individual variables from the list, while the
                           clearvars command removes all variables from the
                           list.  The showvars command displays the current
                           list of optional variables.
           authenticate [yes|no]
                           Normally ntpq does not authenticate requests unless
                           they are write requests.  The command authenticate
                           yes causes ntpq to send authentication with all re-
                           quests it makes.  Authenticated requests causes
                           some servers to handle requests slightly differ-
                           ently.  The command authenticate causes ntpq to
                           display whether or not it is currently authenticat-
                           ing 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 consump-
                           tion.  Variables which ntpq could not decode com-
                           pletely are marked with a trailing '?'.
           debug [more|less|off]
                           With no argument, displays the current debug level.
                           Otherwise, the debugging level is changed as indi-
                           cated.
           delay [milliseconds]
                           Specify a time interval to be added to timestamps
                           included in requests which require authentication.
                           This is used to enable (unreliable) server recon-
                           figuration over long delay network paths or between
                           machines whose clocks are unsynchronized.  Actually
                           the server does not now require timestamps in au-
                           thenticated requests, so this command may be obso-
                           lete.  Without any arguments, displays the current
                           delay.
           drefid [hash|ipv4]
                           Display refids as IPv4 or hash.  Without any argu-
                           ments, 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 either a host name or a numeric ad-
                           dress.  Without any arguments, displays the current
                           host.
           hostnames [yes|no]
                           If yes is specified, host names are printed in in-
                           formation displays.  If no is specified, numeric
                           addresses are printed instead.  The default is yes,
                           unless modified using the command line -n switch.
                           Without any arguments, displays whether host names
                           or numeric addresses are shown.
           keyid [keyid]   This command allows the specification of a key num-
                           ber to be used to authenticate configuration re-
                           quests.  This must correspond to the controlkey key
                           number the server has been configured to use for
                           this purpose.  Without any arguments, displays the
                           current keyid.
           keytype [digest]
                           Specify the digest algorithm to use for authenti-
                           cating requests, with default 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 con-
                           trol 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 argu-
                           ment, 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 remote server.  The only format-
                           ing/interpretation done on the data is to transform
                           nonascii data into a printable (but barely under-
                           standable) 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 displayed in hex format and the asso-
                      ciation number is also displayed.
           associations
                      Display a list of mobilized associations in the form:
                            ind assid status conf reach auth condition
                            last_event cnt

           authinfo   Display the authentication statistics counters: time
                      since reset, stored keys, free keys, key lookups, keys
                      not found, uncached keys, expired keys, encryptions, de-
                      cryptions.
           clocklist [associd]
           cl [associd]
                      Display all clock variables in the variable list for
                      those associations supporting a reference clock.
           clockvar [associd] [name[=value]][,...]
           cv [associd] [name[=value]][,...]
                      Display a list of clock variables for those associations
                      supporting a reference clock.
           :config configuration command line
                      Send the remainder of the command line, including white-
                      space, to the server as a run-time configuration command
                      in the same format as a line in the configuration file.
                      This command is experimental until further notice and
                      clarification.  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 experimental
                      until further notice and clarification.  Authentication
                      is required.
           ifstats    Display status and statistics counters for each local
                      network interface address: interface number, interface
                      name and address or broadcast, drop, flag, ttl, mc, re-
                      ceived, sent, send failed, peers, uptime.  Authentica-
                      tion is required.
           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, ig-
                      nored 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 frequency, maximum error, estimated er-
                      ror, kernel status, pll time constant, precision, fre-
                      quency tolerance, pps frequency, pps stability, pps jit-
                      ter, calibration 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 preci-
                      sion value displayed is in milliseconds as well, unlike
                      the precision system variable.
           lassociations

           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 associa-
                      tions.
           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 facil-
                      ity.  With the exception of sort=[-]sortorder, the op-
                      tions filter the list returned by ntpd(8).  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
                      packets.  The laddr=localaddr option filters entries for
                      packets received on any local address other than
                      localaddr.  resany=hexmask and resall=hexmask filter en-
                      tries 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 re-
                      verse the sort order.  The output columns are:

           passociations
                      Perform the same function as the associations command,
                      except that it uses previously stored data rather than
                      making a new query.

                      Display all system or peer variables.  If the associd is
                      omitted, it is assumed to be zero.
           readvar [associd name[=value] [, ...]]
           rv [associd name[=value] [, ...]]
                      Display the specified system or peer variables.  If
                      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.  If no name is in-
                      cluded, all operative variables in the name space are
                      displayed.  In this case only, if the associd is omit-
                      ted, it is assumed to be zero.  Multiple names are spec-
                      ified 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 represented 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 required.

                      Save the current configuration, including any runtime
                      modifications made by :config or config-from-file, to
                      the NTP server host file filename.  This command will be
                      rejected by the server unless saveconfigdir:
                      miscopt.html#saveconfigdir appears in the ntpd(8) con-
                      figuration file.  filename can use date(1) format speci-

                      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

                      wander, broadcast delay, symm. auth. delay.
           sysstats   Display system uptime and packet counts maintained in
                      the protocol module: uptime, sysstats reset, packets re-
                      ceived, current version, older version, bad length or
                      format, authentication failed, declined, restricted,

           timerstats
                      Display interval timer counters: time since reset, timer
                      overruns, calls to transmit.
           writelist associd
                      Set all system or peer variables included in the vari-
                      able 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 displayed 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 in-
     cludes 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 dis-
     played 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 billboards.

   System Variables
     The following system variables appear in the readlist billboard.  Not all
     variables are displayed in some configurations.

           Variable   Description
           status     system status word: decode.html#sys

           leapsec    NTP seconds when the next leap second is/was inserted
           expire     NTP seconds when the NIST leapseconds file expires
     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 discipline module.

     When the NTPv4 daemon is compiled with the OpenSSL software library, ad-
     ditional system variables are displayed, including some or all of the
     following, depending on the particular Autokey dance:
           Variable   Description
           host       Autokey host name for this host
           ident      Autokey group name for this host
           flags      host flags  (see Autokey specification)
           digest     OpenSSL message digest algorithm

     The bias variable is calculated when the first broadcast packet is re-
     ceived after the calibration volley.  It represents the offset of the
     broadcast subgraph relative to the unicast subgraph.  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, ad-
     ditional peer variables are displayed, including the following:
           Variable   Description
           flags      peer flags (see Autokey specification)
           host       Autokey server name

OPTIONS
     -4, --ipv4
             Force IPv4 name resolution.  This option must not appear in com-
             bination 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 com-
             bination with any of the following options: ipv4.

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

     -c cmd, --command=cmd
             run a command and exit.  This option may appear an unlimited num-
             ber 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 unlim-
             ited number of times.

     -D number, --set-debug-level=number
             Set the debug verbosity level.  This option may appear an unlim-
             ited 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 writ-
             ten 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 pre-
             cedes the output of readvar (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 read-
             var.  Using an environment variable to preset this option in a
             script will enable both older and newer ntpq to behave identi-
             cally in this regard.

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

             Print a list of the peers known to the server as well as a sum-
             mary of their state. This is equivalent to the 'peers' interac-
             tive command.

     -r keyword, --refid=keyword
             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 characters, 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 con-
             figuration 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 configuration ("RC" or ".INI") file(s) and values from envi-
     ronment 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
             autogen-users@lists.sourceforge.net.  Thank you.
