.Sh DESCRIPTION
|
|
.Pp
|
|
The
|
|
.Nm
|
|
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
|
|
.Nm
|
|
utility can also obtain and print a
|
|
list of peers in a common format by sending multiple queries to the
|
|
server.
|
|
.Pp
|
|
If one or more request options is 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
|
|
.Nm
|
|
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
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
Note that in contexts where a host name is expected, a
|
|
.Fl 4
|
|
qualifier preceding the host name forces resolution to the IPv4
|
|
namespace, while a
|
|
.Fl 6
|
|
qualifier forces resolution to the IPv6 namespace.
|
|
For examples and usage, see the
|
|
.Dq NTP Debugging Techniques
|
|
page.
|
|
.Pp
|
|
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 "Internal Commands"
|
|
.Pp
|
|
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.
|
|
.Pp
|
|
A
|
|
number of interactive format commands are executed entirely within
|
|
the
|
|
.Nm
|
|
utility itself and do not result in NTP
|
|
requests being sent to a server.
|
|
These are described following.
|
|
.Bl -tag -width "help [command]" -compact -offset indent
|
|
.It Ic ? Op Ar command
|
|
.It Ic help Op Ar command
|
|
A
|
|
.Ql \&?
|
|
by itself will print a list of all the commands
|
|
known to
|
|
.Nm .
|
|
A
|
|
.Ql \&?
|
|
followed by a command name will print function and usage
|
|
information about the command.
|
|
.It Ic addvars Ar name Ns Oo \&= Ns Ar value Oc Ns Op ,...
|
|
.It Ic rmvars Ar name Ns Op ,...
|
|
.It Ic clearvars
|
|
.It Ic showvars
|
|
The arguments to this command consist of a list of
|
|
items of the form
|
|
.Ar name Ns Op \&= Ns Ar value ,
|
|
where the
|
|
.No \&= Ns Ar value
|
|
is ignored, and can be omitted,
|
|
in requests to the server to read variables.
|
|
The
|
|
.Nm
|
|
utility maintains an internal list in which data to be included in
|
|
messages can be assembled, and displayed or set using the
|
|
.Ic readlist
|
|
and
|
|
.Ic writelist
|
|
commands described below.
|
|
The
|
|
.Ic 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
|
|
.Ic rmvars
|
|
command can be used to remove individual variables from the list,
|
|
while the
|
|
.Ic clearvars
|
|
command removes all variables from the
|
|
list.
|
|
The
|
|
.Ic showvars
|
|
command displays the current list of optional variables.
|
|
.It Ic authenticate Op Cm yes Ns | Ns Cm no
|
|
Normally
|
|
.Nm
|
|
does not authenticate requests unless
|
|
they are write requests.
|
|
The command
|
|
.Ic authenticate Cm yes
|
|
causes
|
|
.Nm
|
|
to send authentication with all requests it
|
|
makes.
|
|
Authenticated requests causes some servers to handle
|
|
requests slightly differently.
|
|
The command
|
|
.Ic authenticate
|
|
causes
|
|
.Nm
|
|
to display whether or not
|
|
it is currently authenticating requests.
|
|
.It Ic cooked
|
|
Causes output from query commands to be "cooked", so that
|
|
variables which are recognized by
|
|
.Nm
|
|
will have their
|
|
values reformatted for human consumption.
|
|
Variables which
|
|
.Nm
|
|
could not decode completely are
|
|
marked with a trailing
|
|
.Ql \&? .
|
|
.It Ic debug Op Cm more Ns | Ns Cm less Ns | Ns Cm off
|
|
With no argument, displays the current debug level.
|
|
Otherwise, the debugging level is changed as indicated.
|
|
.It Ic delay Op 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.
|
|
Without any arguments, displays the current delay.
|
|
.It Ic drefid Op Cm hash Ns | Ns Cm ipv4
|
|
Display refids as IPv4 or hash.
|
|
Without any arguments, displays whether refids are shown as IPv4
|
|
addresses or hashes.
|
|
.It Ic exit
|
|
Exit
|
|
.Nm .
|
|
.It Ic host Op Ar name
|
|
Set the host to which future queries will be sent.
|
|
The
|
|
.Ar name
|
|
may be either a host name or a numeric address.
|
|
Without any arguments, displays the current host.
|
|
.It Ic hostnames Op Cm yes Ns | Ns 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.
|
|
Without any arguments, displays whether host names or numeric addresses
|
|
are shown.
|
|
.It Ic keyid Op Ar keyid
|
|
This command allows the specification of a key number to be
|
|
used to authenticate configuration requests.
|
|
This must correspond
|
|
to the
|
|
.Cm controlkey
|
|
key number the server has been configured to use for this
|
|
purpose.
|
|
Without any arguments, displays the current
|
|
.Ar keyid .
|
|
.It Ic keytype Op Ar digest
|
|
Specify the digest algorithm to use for authenticating requests, with default
|
|
.Cm MD5 .
|
|
If
|
|
.Nm
|
|
was built with OpenSSL support, and OpenSSL is installed,
|
|
.Ar digest
|
|
can be any message digest algorithm supported by OpenSSL.
|
|
If no argument is given, the current
|
|
.Ic keytype Ar digest
|
|
algorithm used is displayed.
|
|
.It Ic ntpversion Op Cm 1 Ns | Ns Cm 2 Ns | Ns Cm 3 Ns | Ns Cm 4
|
|
Sets the NTP version number which
|
|
.Nm
|
|
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.
|
|
.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 poll Oo Ar n Oc Op Cm verbose
|
|
Poll an NTP server in client mode
|
|
.Ar n
|
|
times.
|
|
Poll not implemented yet.
|
|
.It Ic quit
|
|
Exit
|
|
.Nm .
|
|
.It Ic raw
|
|
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.
|
|
.It Ic timeout Op Ar 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
|
|
.Nm
|
|
retries each query once after a timeout, the total waiting time for
|
|
a timeout will be twice the timeout value set.
|
|
.It Ic version
|
|
Display the version of the
|
|
.Nm
|
|
program.
|
|
.El
|
|
.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
|
|
.Ic peers
|
|
command, which sends a series of messages,
|
|
and the
|
|
.Ic mreadlist
|
|
and
|
|
.Ic mreadvar
|
|
commands, which iterate over a range of associations.
|
|
.Bl -tag -width "something" -compact -offset indent
|
|
.It Ic apeers
|
|
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
|
|
.Ic peers
|
|
command except that the
|
|
.Cm refid
|
|
is displayed in hex format and the association number is also displayed.
|
|
.It Ic associations
|
|
Display a list of mobilized associations in the form:
|
|
.Dl ind assid status conf reach auth condition last_event cnt

|
|
.It Ic cv Oo Ar associd Oc Oo Ar name Ns Oo \&= Ns Ar value Oc Ns Oc Ns Op ,...
|
|
Display a list of clock variables for those associations supporting a
|
|
reference clock.
|
|
.It Ic :config Ar "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 configuration file.
|
|
This command is experimental until further notice and clarification.
|
|
Authentication is of course required.
|
|
.It Ic config\-from\-file Ar filename
|
|
Send each line of
|
|
.Ar 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.
|
|
.It Ic ifstats
|
|
Display status and statistics counters for each local network interface address:
|

|
|
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 precision value displayed is in milliseconds as well, unlike the
|
|
precision system variable.
|
|
.It Ic lassociations
|
|
Perform the same function as the associations command, except display
|
|
mobilized and unmobilized associations, including all clients.

|
|
With the exception of
|
|
.Cm sort Ns \&= Ns Oo \&\- Oc Ns Ar sortorder ,
|
|
the options filter the list returned by

Status information is also available on a per\-association basis.
|
|
These words are displayed by the
|
|
.Ic readlist
|
|
and
|
|
.Ic associations
|
|
commands both in hexadecimal and in decoded short tip strings.
|
|
The codes, tips and short explanations are documented on the
|
|
.Lk decode.html "Event Messages and Status Words"
|
|
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.

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.
