It uses the standard NTP mode 6 control 25*2b15cb3dSCy Schubert message formats defined in Appendix B of the NTPv3 specification 26*2b15cb3dSCy Schubert RFC1305. The same formats are used in NTPv4, although some of the 27*2b15cb3dSCy Schubert variable names have changed and new ones added. The description 28*2b15cb3dSCy Schubert on this page is for the NTPv4 variables.</p> 299c2daa00SOllivier Robert<p>The program can 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 <tt>ntpq</tt> can also obtain and print a list of peers in a common format by sending multiple queries to the server.</p> 309c2daa00SOllivier Robert<p>If one or more request options is included on the command line when <tt>ntpq</tt> 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, <tt>ntpq</tt> 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. <tt>ntpq</tt> will prompt for commands if the standard input is a terminal device.</p> 319c2daa00SOllivier Robert<p><tt>ntpq</tt> 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. <tt>ntpq</tt> makes one attempt to retransmit requests, and will time requests out if the remote host is not heard from within a suitable timeout time.</p> 329c2daa00SOllivier Robert<p>Note that in contexts where a host name is expected, a <tt>-4</tt> qualifier preceding the host name forces DNS resolution to the IPv4 namespace, while a <tt>-6</tt> qualifier forces DNS resolution to the IPv6 namespace.</p> 339c2daa00SOllivier Robert<p>For examples and usage, see the <a href="debug.html">NTP Debugging Techniques</a> page.</p> 349c2daa00SOllivier Robert<p>Command line options are described following. Specifying a command line option other than <tt>-i</tt> or <tt>-n</tt> will cause the specified query (queries) to be sent to the indicated host(s) immediately. Otherwise, <tt>ntpq</tt> will attempt to read interactive format commands from the standard input.</p> 359c2daa00SOllivier Robert<dl> 36*2b15cb3dSCy Schubert <dt><tt>-4</tt></dt> 37*2b15cb3dSCy Schubert <dd>Force DNS resolution of following host names on the command line to the IPv4 namespace.</dd> 38*2b15cb3dSCy Schubert <dt><tt>-6</tt></dt> 39*2b15cb3dSCy Schubert <dd>Force DNS resolution of following host names on the command line to the IPv6 namespace.</dd> 40*2b15cb3dSCy Schubert <dt><tt>-c</tt></dt> 41*2b15cb3dSCy Schubert <dd>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).

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 <tt>></tt>, followed by a file name, to the command line. A number of interactive format commands are executed entirely within the <tt>ntpq</tt> program itself and do not result in NTP mode-6 requests being sent to a server. These are described following.</p> 539c2daa00SOllivier Robert<dl> 54*2b15cb3dSCy Schubert <dt id="help"><tt>?

The <tt>addvars</tt> command allows variables and 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 <tt>rmvars</tt> command can be used to remove individual variables from the list, while the <tt>clearlist</tt> command removes all variables from the list.</dd> 61*2b15cb3dSCy Schubert <dt id="cooked"><tt>cooked</tt></dt> 62*2b15cb3dSCy Schubert <dd>Display server messages in prettyprint format.</dd> 63*2b15cb3dSCy Schubert <dt id="debug"><tt>debug more | less | off</tt></dt> 64*2b15cb3dSCy Schubert <dd>Turns internal query program debugging on and off.</dd> 65*2b15cb3dSCy Schubert <dt id="delay"><tt>delay <i>milliseconds</i></tt></dt> 66*2b15cb3dSCy Schubert <dd>Specify a time interval to be added to timestamps included in requests which require authentication.

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 mode-6 message to the server and expect a single response message. The exceptions are the <tt>peers</tt> command, which sends a series of messages, and the <tt>mreadlist</tt> and <tt>mreadvar</tt> commands, which iterate over a range of associations.</p> 889c2daa00SOllivier Robert<dl> 89*2b15cb3dSCy Schubert <dt id="as"><tt>associations</tt></dt> 90*2b15cb3dSCy Schubert <dd>Display a list of mobilized associations in the form</dd> 91*2b15cb3dSCy Schubert <dd><tt>ind assid status conf reach auth condition last_event cnt</tt></dd> 929c2daa00SOllivier Robert <dd> 93*2b15cb3dSCy Schubert <table width="100%" border="1" cellspacing="2" cellpadding="2"> 94*2b15cb3dSCy Schubert <tr> 95*2b15cb3dSCy Schubert <td>Variable</td> 96*2b15cb3dSCy Schubert <td>Description</td> 97*2b15cb3dSCy Schubert </tr> 98*2b15cb3dSCy Schubert <tr> 99*2b15cb3dSCy Schubert <td><tt>ind</tt></td> 100*2b15cb3dSCy Schubert <td>index on this list</td> 101*2b15cb3dSCy Schubert </tr> 102*2b15cb3dSCy Schubert <tr> 103*2b15cb3dSCy Schubert <td><tt>assid</tt></td> 104*2b15cb3dSCy Schubert <td>association ID</td> 105*2b15cb3dSCy Schubert </tr> 106*2b15cb3dSCy Schubert <tr> 107*2b15cb3dSCy Schubert <td><tt>status</tt></td> 108*2b15cb3dSCy Schubert <td><a href="decode.html#peer">peer status word</a></td> 109*2b15cb3dSCy Schubert </tr> 110*2b15cb3dSCy Schubert <tr> 111*2b15cb3dSCy Schubert <td><tt>conf</tt></td> 112*2b15cb3dSCy Schubert <td><tt>yes</tt>: persistent, <tt>no</tt>: ephemeral</td> 113*2b15cb3dSCy Schubert </tr> 114*2b15cb3dSCy Schubert <tr> 115*2b15cb3dSCy Schubert <td><tt>reach</tt></td> 116*2b15cb3dSCy Schubert <td><tt>yes</tt>: reachable, <tt>no</tt>: unreachable</td> 117*2b15cb3dSCy Schubert </tr> 118*2b15cb3dSCy Schubert <tr> 119*2b15cb3dSCy Schubert <td><tt>auth</tt></td> 120*2b15cb3dSCy Schubert <td><tt>ok</tt>, <tt>yes</tt>, <tt>bad</tt> and <tt>none</tt></td> 121*2b15cb3dSCy Schubert </tr> 122*2b15cb3dSCy Schubert <tr> 123*2b15cb3dSCy Schubert <td><tt>condition</tt></td> 124*2b15cb3dSCy Schubert <td>selection status (see the <tt>select</tt> field of the <a href="decode.html#peer">peer status word</a>)</td> 125*2b15cb3dSCy Schubert </tr> 126*2b15cb3dSCy Schubert <tr> 127*2b15cb3dSCy Schubert <td><tt>last_event</tt></td> 128*2b15cb3dSCy Schubert <td>event report (see the <tt>event</tt> field of the <a href="decode.html#peer">peer status word</a>)</td> 129*2b15cb3dSCy Schubert </tr> 130*2b15cb3dSCy Schubert <tr> 131*2b15cb3dSCy Schubert <td><tt>cnt</tt></td> 132*2b15cb3dSCy Schubert <td>event count (see the <tt>count</tt> field of the <a href="decode.html#peer">peer status word</a>)</td> 133*2b15cb3dSCy Schubert </tr> 134*2b15cb3dSCy Schubert </table> 135*2b15cb3dSCy Schubert </dd> 136*2b15cb3dSCy Schubert <dt id="cv"><tt>clockvar <i>assocID</i> [<i>name</i> [ = <i>value</i> [...]] [...]</tt><br> 137*2b15cb3dSCy Schubert <tt>cv <i>assocID</i> [<i>name</i> [ = <i>value</i> [...] ][...]</tt></dt> 138*2b15cb3dSCy Schubert <dd>Display a list of <a href="#clock">clock variables</a> for those associations supporting a reference clock.</dd> 139*2b15cb3dSCy Schubert <dt id=":config"><tt>:config [...]</tt></dt> 140*2b15cb3dSCy Schubert <dd>Send the remainder of the command line, including whitespace, to the server as a run-time configuration command in the same format as the configuration file.
