.SH NAME
\f\*[B-Font]ntpq\fP
\- standard NTP query program
.SH SYNOPSIS
\f\*[B-Font]ntpq\fP
.\" Mixture of short (flag) options and long options
[\f\*[B-Font]\-flags\f[]]
[\f\*[B-Font]\-flag\f[] [\f\*[I-Font]value\f[]]]

.SH DESCRIPTION
.sp \n(Ppu
.ne 2

The
\f\*[B-Font]ntpq\fP
utility program is used to query NTP servers to monitor NTP operations
and performance, 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
\f\*[B-Font]ntpq\fP
utility can also obtain and print a
list of peers in a common format by sending multiple queries to the
server.
.sp \n(Ppu
.ne 2

If one or more request options is included on the command line
when
\f\*[B-Font]ntpq\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]ntpq\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]ntpq\fP
utility will prompt for
commands if the standard input is a terminal device.
.sp \n(Ppu
.ne 2

\f\*[B-Font]ntpq\fP
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
\f\*[B-Font]ntpq\fP
utility makes
one 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

Note that in contexts where a host name is expected, a
\f\*[B-Font]\-4\f[]
qualifier preceding the host name forces resolution to the IPv4
namespace, while a
\f\*[B-Font]\-6\f[]
qualifier forces resolution to the IPv6 namespace.
For examples and usage, see the
\*[Lq]NTP Debugging Techniques\*[Rq]
page.
.sp \n(Ppu
.ne 2

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]ntpq\fP
will attempt to read
interactive format commands from the standard input.
.SS "Internal Commands"
.sp \n(Ppu
.ne 2

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.
.sp \n(Ppu
.ne 2

A
number of interactive format commands are executed entirely within
the
\f\*[B-Font]ntpq\fP
utility itself and do not result in NTP
requests being sent to a server.
These are described following.
.TP 15
.NOP \f\*[B-Font]?\f[] [\f\*[I-Font]command\f[]]
.br
.ns
.TP 15
.NOP \f\*[B-Font]help\f[] [\f\*[I-Font]command\f[]]
A
\[oq]\&?\[cq]
by itself will print a list of all the commands
known to
\f\*[B-Font]ntpq\fP.
A
\[oq]\&?\[cq]
followed by a command name will print function and usage
information about the command.
.br
.ns
.TP 15
.NOP \f\*[B-Font]addvars\f[] \f\*[I-Font]name\f[][\&=\f\*[I-Font]value\f[]][,...]
.br
.ns
.TP 15
.NOP \f\*[B-Font]rmvars\f[] \f\*[I-Font]name\f[][,...]
.br
.ns
.TP 15
.NOP \f\*[B-Font]clearvars\f[]
.br
.ns
.TP 15
.NOP \f\*[B-Font]showvars\f[]
The arguments to this command consist of a list of
items of the form
\f\*[I-Font]name\f[][\&=\f\*[I-Font]value\f[]],
where the
.NOP \&=\f\*[I-Font]value\f[]
is ignored, and can be omitted,
in requests to the server to read variables.
The
\f\*[B-Font]ntpq\fP
utility maintains an internal list in which data to be included in
messages can be assembled, and displayed or set using the
\f\*[B-Font]readlist\f[]
and
\f\*[B-Font]writelist\f[]
commands described below.
The
\f\*[B-Font]addvars\f[]
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
\f\*[B-Font]rmvars\f[]
command can be used to remove individual variables from the list,
while the
\f\*[B-Font]clearvars\f[]
command removes all variables from the
list.
The
\f\*[B-Font]showvars\f[]
command displays the current list of optional variables.
.br
.ns
.TP 15
.NOP \f\*[B-Font]authenticate\f[] [\f\*[B-Font]yes\f[]|\f\*[B-Font]no\f[]]
Normally
\f\*[B-Font]ntpq\fP
does not authenticate requests unless
they are write requests.
The command
\f\*[B-Font]authenticate\f[] \f\*[B-Font]yes\f[]
causes
\f\*[B-Font]ntpq\fP
to send authentication with all requests it
makes.
Authenticated requests causes some servers to handle
requests slightly differently.
The command
\f\*[B-Font]authenticate\f[]
causes
\f\*[B-Font]ntpq\fP
to display whether or not
it is currently authenticating requests.
.br
.ns
.TP 15
.NOP \f\*[B-Font]cooked\f[]
Causes output from query commands to be "cooked", so that
variables which are recognized by
\f\*[B-Font]ntpq\fP
will have their
values reformatted for human consumption.
Variables which
\f\*[B-Font]ntpq\fP
could not decode completely are
marked with a trailing
\[oq]\&?\[cq].
.br
.ns
.TP 15
.NOP \f\*[B-Font]debug\f[] [\f\*[B-Font]more\f[]|\f\*[B-Font]less\f[]|\f\*[B-Font]off\f[]]
With no argument, displays the current debug level.
Otherwise, the debugging level is changed as indicated.
.br
.ns
.TP 15
.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.
Without any arguments, displays the current delay.
.br
.ns
.TP 15
.NOP \f\*[B-Font]drefid\f[] [\f\*[B-Font]hash\f[]|\f\*[B-Font]ipv4\f[]]
Display refids as IPv4 or hash.
Without any arguments, displays whether refids are shown as IPv4
addresses or hashes.
.br
.ns
.TP 15
.NOP \f\*[B-Font]exit\f[]
Exit
\f\*[B-Font]ntpq\fP.
.br
.ns
.TP 15
.NOP \f\*[B-Font]host\f[] [\f\*[I-Font]name\f[]]
Set the host to which future queries will be sent.
The
\f\*[I-Font]name\f[]
may be either a host name or a numeric address.
Without any arguments, displays the current host.
.br
.ns
.TP 15
.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.
Without any arguments, displays whether host names or numeric addresses
are shown.
.br
.ns
.TP 15
.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 the
\f\*[B-Font]controlkey\f[]
key number the server has been configured to use for this
purpose.
Without any arguments, displays the current
\f\*[I-Font]keyid\f[].
.br
.ns
.TP 15
.NOP \f\*[B-Font]keytype\f[] [\f\*[I-Font]digest\f[]]
Specify the digest algorithm to use for authenticating requests, with default
\f\*[B-Font]MD5\f[].
If
\f\*[B-Font]ntpq\fP
was built with OpenSSL support, and OpenSSL is installed,
\f\*[I-Font]digest\f[]
can be any message digest algorithm supported by OpenSSL.
If no argument is given, the current
\f\*[B-Font]keytype\f[] \f\*[I-Font]digest\f[]
algorithm used is displayed.
.br
.ns
.TP 15
.NOP \f\*[B-Font]ntpversion\f[] [\f\*[B-Font]1\f[]|\f\*[B-Font]2\f[]|\f\*[B-Font]3\f[]|\f\*[B-Font]4\f[]]
Sets the NTP version number which
\f\*[B-Font]ntpq\fP
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.
.br
.ns
.TP 15
.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.
.br
.ns
.TP 15
.NOP \f\*[B-Font]poll\f[] [\f\*[I-Font]n\f[]] [\f\*[B-Font]verbose\f[]]
Poll an NTP server in client mode
\f\*[I-Font]n\f[]
times.
Poll not implemented yet.
.br
.ns
.TP 15
.NOP \f\*[B-Font]quit\f[]
Exit
\f\*[B-Font]ntpq\fP.
.br
.ns
.TP 15
.NOP \f\*[B-Font]raw\f[]
Causes all output from query commands is printed as received
from the remote server.
The only formating/interpretation done on
the data is to transform nonascii data into a printable (but barely
understandable) form.
.br
.ns
.TP 15
.NOP \f\*[B-Font]timeout\f[] [\f\*[I-Font]milliseconds\f[]]
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
\f\*[B-Font]ntpq\fP
retries each query once after a timeout, the total waiting time for
a timeout will be twice the timeout value set.
.br
.ns
.TP 15
.NOP \f\*[B-Font]version\f[]
Display the version of the
\f\*[B-Font]ntpq\fP
program.
.PP
.SS "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
\f\*[B-Font]peers\f[]
command, which sends a series of messages,
and the
\f\*[B-Font]mreadlist\f[]
and
\f\*[B-Font]mreadvar\f[]
commands, which iterate over a range of associations.
.TP 10
.NOP \f\*[B-Font]apeers\f[]
Display a list of peers in the form:
.Dl [tally]remote refid assid st t when pool reach delay offset jitter
where the output is just like the
\f\*[B-Font]peers\f[]
command except that the
\f\*[B-Font]refid\f[]
is displayed in hex format and the association number is also displayed.
.br
.ns
.TP 10
.NOP \f\*[B-Font]associations\f[]

.SH "OPTIONS"
.TP
.NOP \f\*[B-Font]\-4\f[], \f\*[B-Font]\-\-ipv4\f[]
Force IPv4 name resolution.
This option must not appear in combination with any of the following options:
ipv6.
.sp
Force resolution of following host names on the command line
to the IPv4 namespace.
.TP
.NOP \f\*[B-Font]\-6\f[], \f\*[B-Font]\-\-ipv6\f[]
Force IPv6 name resolution.
This option must not appear in combination with any of the following options:
ipv4.
.sp
Force resolution of following host names on the command line
to the IPv6 namespace.
.TP
.NOP \f\*[B-Font]\-c\f[] \f\*[I-Font]cmd\f[], \f\*[B-Font]\-\-command\f[]=\f\*[I-Font]cmd\f[]
run a command and exit.
This option may appear an unlimited number of times.
.sp
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).
.TP
.NOP \f\*[B-Font]\-d\f[], \f\*[B-Font]\-\-debug\-level\f[]
Increase debug verbosity level.
This option may appear an unlimited number of times.
.sp
.TP
.NOP \f\*[B-Font]\-D\f[] \f\*[I-Font]number\f[], \f\*[B-Font]\-\-set\-debug\-level\f[]=\f\*[I-Font]number\f[]
Set the debug verbosity level.
This option may appear an unlimited number of times.
This option takes an integer number as its argument.
.sp
.TP
.NOP \f\*[B-Font]\-i\f[], \f\*[B-Font]\-\-interactive\f[]
Force ntpq to operate in interactive mode.
This option must not appear in combination with any of the following options:
command, peers.
.sp
Force \fBntpq\fP to operate in interactive mode.
Prompts will be written to the standard output and
commands read from the standard input.
.TP
.NOP \f\*[B-Font]\-n\f[], \f\*[B-Font]\-\-numeric\f[]
numeric host addresses.
.sp
Output all host addresses in dotted-quad numeric format rather than
converting to the canonical host names.
.TP
.NOP \f\*[B-Font]\-\-old\-rv\f[]
Always output status line with readvar.
.sp
By default, \fBntpq\fP now suppresses the \fBassocid=...\fP
line that precedes the output of \fBreadvar\fP
(alias \fBrv\fP) when a single variable is requested, such as
\fBntpq \-c "rv 0 offset"\fP.
This option causes \fBntpq\fP to include both lines of output
for a single-variable \fBreadvar\fP.
Using an environment variable to
preset this option in a script will enable both older and
newer \fBntpq\fP to behave identically in this regard.
.TP
.NOP \f\*[B-Font]\-p\f[], \f\*[B-Font]\-\-peers\f[]
Print a list of the peers.
This option must not appear in combination with any of the following options:
interactive.
.sp
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.
.TP
.NOP \f\*[B-Font]\-r\f[] \f\*[I-Font]keyword\f[], \f\*[B-Font]\-\-refid\f[]=\f\*[I-Font]keyword\f[]
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:
.in +4
.nf
.na
hash ipv4
.fi
or their numeric equivalent.
.in -4
.sp
The default
\f\*[I-Font]keyword\f[]
for this option is:
.ti +4
 ipv4
.sp
Set the default display format for S2+ refids.
.TP
.NOP \f\*[B-Font]\-w\f[], \f\*[B-Font]\-\-wide\f[]
Display the full 'remote' value.
.sp
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.
.TP
.NOP \f\*[B-Font]\-\&?\f[], \f\*[B-Font]\-\-help\f[]
Display usage information and exit.
.TP
.NOP \f\*[B-Font]\-\&!\f[], \f\*[B-Font]\-\-more-help\f[]
Pass the extended usage information through a pager.
.TP
.NOP \f\*[B-Font]\->\f[] [\f\*[I-Font]cfgfile\f[]], \f\*[B-Font]\-\-save-opts\f[] [=\f\*[I-Font]cfgfile\f[]]
Save the option state to \fIcfgfile\fP.  The default is the \fIlast\fP
configuration file listed in the \fBOPTION PRESETS\fP section, below.
The command will exit after updating the config file.
.TP
.NOP \f\*[B-Font]\-<\f[] \f\*[I-Font]cfgfile\f[], \f\*[B-Font]\-\-load-opts\f[]=\f\*[I-Font]cfgfile\f[], \f\*[B-Font]\-\-no-load-opts\f[]
Load options from \fIcfgfile\fP.
The \fIno-load-opts\fP form will disable the loading
of earlier config/rc/ini files.  \fI\-\-no-load-opts\fP is handled early,
out of order.
.TP
.NOP \f\*[B-Font]\-\-version\f[] [{\f\*[I-Font]v|c|n\f[]}]
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.
.PP
.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
  \fBNTPQ_<option-name>\fP or \fBNTPQ\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 "ENVIRONMENT"
See \fBOPTION PRESETS\fP for configuration environment variables.
.SH "FILES"
See \fBOPTION PRESETS\fP for configuration files.
.SH "EXIT STATUS"
One of the following exit values will be returned:
.TP
.NOP 0 " (EXIT_SUCCESS)"
Successful program execution.
.TP
.NOP 1 " (EXIT_FAILURE)"
The operation failed or the command syntax was not valid.
.TP
.NOP 66 " (EX_NOINPUT)"
A specified configuration file could not be loaded.
.TP
.NOP 70 " (EX_SOFTWARE)"
libopts had an internal operational error.  Please report
it to autogen-users@lists.sourceforge.net.  Thank you.
