Op Ar command 108.It Ic help Op Ar command 109A 110.Ql \&? 111by itself will print a list of all the commands 112known to 113.Nm . 114A 115.Ql \&? 116followed by a command name will print function and usage 117information about the command. 118.It Ic addvars Ar name Ns Oo \&= Ns Ar value Oc Ns Op ,... 119.It Ic rmvars Ar name Ns Op ,... 120.It Ic clearvars 121.It Ic showvars 122The arguments to this command consist of a list of 123items of the form 124.Ar name Ns Op \&= Ns Ar value , 125where the 126.No \&= Ns Ar value 127is ignored, and can be omitted, 128in requests to the server to read variables. 129The 130.Nm 131utility maintains an internal list in which data to be included in 132messages can be assembled, and displayed or set using the 133.Ic readlist 134and 135.Ic writelist 136commands described below. 137The 138.Ic addvars 139command allows variables and their optional values to be added to 140the list. 141If more than one variable is to be added, the list should 142be comma\-separated and not contain white space. 143The 144.Ic rmvars 145command can be used to remove individual variables from the list, 146while the 147.Ic clearvars 148command removes all variables from the 149list. 150The 151.Ic showvars 152command displays the current list of optional variables. 153.It Ic authenticate Op Cm yes Ns | Ns Cm no 154Normally 155.Nm 156does not authenticate requests unless 157they are write requests. 158The command 159.Ic authenticate Cm yes 160causes 161.Nm 162to send authentication with all requests it 163makes. 164Authenticated requests causes some servers to handle 165requests slightly differently. 166The command 167.Ic authenticate 168causes 169.Nm 170to display whether or not 171it is currently authenticating requests. 172.It Ic cooked 173Causes output from query commands to be "cooked", so that 174variables which are recognized by 175.Nm 176will have their 177values reformatted for human consumption. 178Variables which 179.Nm 180could not decode completely are 181marked with a trailing 182.Ql \&? . 183.It Ic debug Op Cm more Ns | Ns Cm less Ns | Ns Cm off 184With no argument, displays the current debug level. 185Otherwise, the debugging level is changed as indicated. 186.It Ic delay Op Ar milliseconds 187Specify a time interval to be added to timestamps included in 188requests which require authentication. 189This is used to enable 190(unreliable) server reconfiguration over long delay network paths 191or between machines whose clocks are unsynchronized. 192Actually the 193server does not now require timestamps in authenticated requests, 194so this command may be obsolete. 195Without any arguments, displays the current delay. 196.It Ic drefid Op Cm hash Ns | Ns Cm ipv4 197Display refids as IPv4 or hash. 198Without any arguments, displays whether refids are shown as IPv4 199addresses or hashes. 200.It Ic exit 201Exit 202.Nm . 203.It Ic host Op Ar name 204Set the host to which future queries will be sent. 205The 206.Ar name 207may be either a host name or a numeric address. 208Without any arguments, displays the current host. 209.It Ic hostnames Op Cm yes Ns | Ns Cm no 210If 211.Cm yes 212is specified, host names are printed in 213information displays. 214If 215.Cm no 216is specified, numeric 217addresses are printed instead. 218The default is 219.Cm yes , 220unless 221modified using the command line 222.Fl n 223switch. 224Without any arguments, displays whether host names or numeric addresses 225are shown. 226.It Ic keyid Op Ar keyid 227This command allows the specification of a key number to be 228used to authenticate configuration requests. 229This must correspond 230to the 231.Cm controlkey 232key number the server has been configured to use for this 233purpose. 234Without any arguments, displays the current 235.Ar keyid . 236.It Ic keytype Op Ar digest 237Specify the digest algorithm to use for authenticating requests, with default 238.Cm MD5 . 239If 240.Nm 241was built with OpenSSL support, and OpenSSL is installed, 242.Ar digest 243can be any message digest algorithm supported by OpenSSL. 244If no argument is given, the current 245.Ic keytype Ar digest 246algorithm used is displayed. 247.It Ic ntpversion Op Cm 1 Ns | Ns Cm 2 Ns | Ns Cm 3 Ns | Ns Cm 4 248Sets the NTP version number which 249.Nm 250claims in 251packets. 252Defaults to 3, and note that mode 6 control messages (and 253modes, for that matter) didn't exist in NTP version 1. 254There appear 255to be no servers left which demand version 1. 256With no argument, displays the current NTP version that will be used 257when communicating with servers. 258.It Ic passwd 259This command prompts you to type in a password (which will not 260be echoed) which will be used to authenticate configuration 261requests. 262The password must correspond to the key configured for 263use by the NTP server for this purpose if such requests are to be 264successful. 265.It Ic poll Oo Ar n Oc Op Cm verbose 266Poll an NTP server in client mode 267.Ar n 268times. 269Poll not implemented yet. 270.It Ic quit 271Exit 272.Nm . 273.It Ic raw 274Causes all output from query commands is printed as received 275from the remote server. 276The only formating/interpretation done on 277the data is to transform nonascii data into a printable (but barely 278understandable) form. 279.It Ic timeout Op Ar milliseconds 280Specify a timeout period for responses to server queries. 281The 282default is about 5000 milliseconds. 283Without any arguments, displays the current timeout period. 284Note that since 285.Nm 286retries each query once after a timeout, the total waiting time for 287a timeout will be twice the timeout value set. 288.It Ic version 289Display the version of the 290.Nm 291program. 292.El 293.Ss "Control Message Commands" 294Association ids are used to identify system, peer and clock variables. 295System variables are assigned an association id of zero and system name 296space, while each association is assigned a nonzero association id and 297peer namespace. 298Most control commands send a single message to the server and expect a 299single response message. 300The exceptions are the 301.Ic peers 302command, which sends a series of messages, 303and the 304.Ic mreadlist 305and 306.Ic mreadvar 307commands, which iterate over a range of associations. 308.Bl -tag

configuration command in the same format as a line 347in the configuration file. 348This command is experimental until further notice and clarification. 349Authentication is of course required. 350.It Ic config\-from\-file Ar filename 351Send each line of 352.Ar filename 353to the server as run\-time configuration commands in the same format as 354lines in the configuration file. 355This command is experimental until further notice and clarification. 356Authentication is required. 357.It Ic ifstats 358Display status and statistics counters for each local network interface address: 359interface number, interface name and address or broadcast, drop, flag, 360ttl, mc, received, sent, send failed, peers, uptime. 361Authentication is required. 362.It Ic iostats 363Display network and reference

unlike the 377precision system variable. 378.It Ic lassociations 379Perform the same function as the associations command, except display 380mobilized and unmobilized associations, including all
