Op Ar command 110.It Ic help Op Ar command 111A 112.Ql \&? 113by itself will print a list of all the commands 114known to 115.Nm . 116A 117.Ql \&? 118followed by a command name will print function and usage 119information about the command. 120.It Ic addvars Ar name Ns Oo \&= Ns Ar value Oc Ns Op ,... 121.It Ic rmvars Ar name Ns Op ,... 122.It Ic clearvars 123.It Ic showvars 124The arguments to this command consist of a list of 125items of the form 126.Ar name Ns Op \&= Ns Ar value , 127where the 128.No \&= Ns Ar value 129is ignored, and can be omitted, 130in requests to the server to read variables. 131The 132.Nm 133utility maintains an internal list in which data to be included in 134messages can be assembled, and displayed or set using the 135.Ic readlist 136and 137.Ic writelist 138commands described below. 139The 140.Ic addvars 141command allows variables and their optional values to be added to 142the list. 143If more than one variable is to be added, the list should 144be comma\-separated and not contain white space. 145The 146.Ic rmvars 147command can be used to remove individual variables from the list, 148while the 149.Ic clearvars 150command removes all variables from the 151list. 152The 153.Ic showvars 154command displays the current list of optional variables. 155.It Ic authenticate Op Cm yes Ns | Ns Cm no 156Normally 157.Nm 158does not authenticate requests unless 159they are write requests. 160The command 161.Ic authenticate Cm yes 162causes 163.Nm 164to send authentication with all requests it 165makes. 166Authenticated requests causes some servers to handle 167requests slightly differently. 168The command 169.Ic authenticate 170causes 171.Nm 172to display whether or not 173it is currently authenticating requests. 174.It Ic cooked 175Causes output from query commands to be "cooked", so that 176variables which are recognized by 177.Nm 178will have their 179values reformatted for human consumption. 180Variables which 181.Nm 182could not decode completely are 183marked with a trailing 184.Ql \&? . 185.It Ic debug Op Cm more Ns | Ns Cm less Ns | Ns Cm off 186With no argument, displays the current debug level. 187Otherwise, the debugging level is changed as indicated. 188.It Ic delay Op Ar milliseconds 189Specify a time interval to be added to timestamps included in 190requests which require authentication. 191This is used to enable 192(unreliable) server reconfiguration over long delay network paths 193or between machines whose clocks are unsynchronized. 194Actually the 195server does not now require timestamps in authenticated requests, 196so this command may be obsolete. 197Without any arguments, displays the current delay. 198.It Ic drefid Op Cm hash Ns | Ns Cm ipv4 199Display refids as IPv4 or hash. 200Without any arguments, displays whether refids are shown as IPv4 201addresses or hashes. 202.It Ic exit 203Exit 204.Nm . 205.It Ic host Op Ar name 206Set the host to which future queries will be sent. 207The 208.Ar name 209may be either a host name or a numeric address. 210Without any arguments, displays the current host. 211.It Ic hostnames Op Cm yes Ns | Ns Cm no 212If 213.Cm yes 214is specified, host names are printed in 215information displays. 216If 217.Cm no 218is specified, numeric 219addresses are printed instead. 220The default is 221.Cm yes , 222unless 223modified using the command line 224.Fl n 225switch. 226Without any arguments, displays whether host names or numeric addresses 227are shown. 228.It Ic keyid Op Ar keyid 229This command allows the specification of a key number to be 230used to authenticate configuration requests. 231This must correspond 232to the 233.Cm controlkey 234key number the server has been configured to use for this 235purpose. 236Without any arguments, displays the current 237.Ar keyid . 238.It Ic keytype Op Ar digest 239Specify the digest algorithm to use for authenticating requests, with default 240.Cm MD5 . 241If 242.Nm 243was built with OpenSSL support, and OpenSSL is installed, 244.Ar digest 245can be any message digest algorithm supported by OpenSSL. 246If no argument is given, the current 247.Ic keytype Ar digest 248algorithm used is displayed. 249.It Ic ntpversion Op Cm 1 Ns | Ns Cm 2 Ns | Ns Cm 3 Ns | Ns Cm 4 250Sets the NTP version number which 251.Nm 252claims in 253packets. 254Defaults to 3, and note that mode 6 control messages (and 255modes, for that matter) didn't exist in NTP version 1. 256There appear 257to be no servers left which demand version 1. 258With no argument, displays the current NTP version that will be used 259when communicating with servers. 260.It Ic passwd 261This command prompts you to type in a password (which will not 262be echoed) which will be used to authenticate configuration 263requests. 264The password must correspond to the key configured for 265use by the NTP server for this purpose if such requests are to be 266successful. 267.It Ic poll Oo Ar n Oc Op Cm verbose 268Poll an NTP server in client mode 269.Ar n 270times. 271Poll not implemented yet. 272.It Ic quit 273Exit 274.Nm . 275.It Ic raw 276Causes all output from query commands is printed as received 277from the remote server. 278The only formating/interpretation done on 279the data is to transform nonascii data into a printable (but barely 280understandable) form. 281.It Ic timeout Op Ar milliseconds 282Specify a timeout period for responses to server queries. 283The 284default is about 5000 milliseconds. 285Without any arguments, displays the current timeout period. 286Note that since 287.Nm 288retries each query once after a timeout, the total waiting time for 289a timeout will be twice the timeout value set. 290.It Ic version 291Display the version of the 292.Nm 293program. 294.El 295.Ss "Control Message Commands" 296Association ids are used to identify system, peer and clock variables. 297System variables are assigned an association id of zero and system name 298space, while each association is assigned a nonzero association id and 299peer namespace. 300Most control commands send a single message to the server and expect a 301single response message. 302The exceptions are the 303.Ic peers 304command, which sends a series of messages, 305and the 306.Ic mreadlist 307and 308.Ic mreadvar 309commands, which iterate over a range of associations. 310.Bl -tag

configuration command in the same format as a line 349in the configuration file. 350This command is experimental until further notice and clarification. 351Authentication is of course required. 352.It Ic config\-from\-file Ar filename 353Send each line of 354.Ar filename 355to the server as run\-time configuration commands in the same format as 356lines in the configuration file. 357This command is experimental until further notice and clarification. 358Authentication is required. 359.It Ic ifstats 360Display status and statistics counters for each local network interface address: 361interface number, interface name and address or broadcast, drop, flag, 362ttl, mc, received, sent, send failed, peers, uptime. 363Authentication is required. 364.It Ic iostats 365Display network and reference clock I/O statistics: 366time since reset, receive buffers, free receive buffers, used receive buffers, 367low water refills, dropped packets, ignored packets, received packets, 368packets sent,

666Status information is also available on a per\-association basis. 667These words are displayed by the 668.Ic readlist 669and 670.Ic associations 671commands both in hexadecimal and in decoded short tip strings. 672The codes, tips and short explanations are documented on the 673.Lk decode.html "Event Messages and Status Words" 674page. 675The page also includes a list of system and peer messages, 676the code for the latest of which is included in the status word. 677.Pp 678Information resulting from protocol machine state transitions 679is displayed using an informal set of ASCII strings called 680.Lk decode.html#kiss "kiss codes" . 681The original purpose was for kiss\-o'\-death (KoD) packets 682sent by the server to advise the client of an unusual condition. 683They are now displayed, when appropriate, 684in the reference identifier field in various billboards. 685.Ss System Variables 686The following system variables appear in the 687.Ic readlist 688billboard. 689Not
