key .Op Fl e Ar authdelay .Op Fl k Ar keyfile .Op Fl o Ar version .Op Fl p Ar samples .Op Fl t Ar timeout .Ar server .Op Ar ... .Sh DESCRIPTION .Nm sets the local date and time by polling the Network Time Protocol (NTP) server(s) given as the .Ar server arguments to determine the correct time. It must be run as root on the local host. A number of samples are obtained from each of the servers specified and a subset of the NTP clock filter and selection algorithms are applied to select the best of these. Note that the accuracy and reliability of .Nm depends on the number of servers, the number of polls each time it is run and the interval between runs. .Pp .Nm can be run manually as necessary to set the host clock, or it can be run from the host startup script to set the clock at boot time. This is useful in some cases to set the clock initially before starting the NTP daemon .Xr xntpd 8 . It is also possible to run .Nm from a .Xr cron 8 script. However, it is important to note that .Nm with contrived .Xr cron 8 scripts is no substitute for the NTP daemon, which uses sophisticated algorithms to maximize accuracy and reliability while minimizing resource use. Finally, since .Nm does not discipline the host clock frequency as does .Xr xntpd 8 , the accuracy using .Nm is limited. .Pp Time adjustments are made by .Nm in one of two ways. If .Nm determines the clock is in error more than 0.5 second it will simply step the time by calling the system .Xr settimeofday 2 routine. If the error is less than 0.5 seconds, it will slew the time by calling the system .Xr adjtime 2 routine. The latter technique is less disruptive and more accurate when the error is small, and works quite well when .Nm is run by .Xr cron 8 every hour or two. .Pp .Nm will decline to set the date if an NTP server daemon (e.g., .Xr xntpd 8 ) is running on the same host. When running .Nm on a regular basis from .Xr cron 8 as an alternative to running a daemon, doing so once every hour or two will result in precise enough timekeeping to avoid stepping the clock. .Pp The following options are available: .Bl -tag -width indent .It Fl a Ar key Enable the authentication function and specify the key identifier to be used for authentication as the argument .Ar key .Nm The keys and key identifiers must match in both the client and server key files. The default is to disable the authentication function. .It Fl B Force the time to always be slewed using the .Xr adjtime 2 system call, even if the measured offset is greater than +-128 ms. The default is to step the time using .Xr settimeofday 2 if the offset is greater than +-128 ms. Note that, if the offset is much greater than +-128 ms in this case, that it can take a long time (hours) to slew the clock to the correct value. During this time. the host should not be used to synchronize clients. .It Fl b Force the time to be stepped using the .Xr settimeofday 2 system call, rather than slewed (default) using the .Xr adjtime 2 system call. This option should be used when called from a startup file at boot time. .It Fl d Enable the debugging mode, in which .Nm will go through all the steps, but not adjust the local clock. Information useful for general debugging will also be printed. .It Fl e Ar authdelay Specify the processing delay to perform an authentication function as the value .Ar authdelay , in seconds and fraction (see .Xr xntpd 8 for details). This number is usually small enough to be negligible for most purposes, though specifying a value may improve timekeeping on very slow CPU's. .It Fl k Ar keyfile Specify the path for the authentication key file as the string .Ar keyfile . The default is .Pa /etc/ntp.keys . This file should be in the format described in .Xr xntpd 8 . .It Fl o Ar version Specify the NTP version for outgoint packets as the integer .Ar version , which can be 1 or 2. The default is 3. This allows .Nm to be used with older NTP versions. .It Fl p Ar samples Specify the number of samples to be acquired from each server as the integer .Ar samples , with values from 1 to 8 inclusive. The default is 4. .It Fl q Query only - don't set the clock. .It Fl s Divert logging output from the standard output (default) to the system .Xr syslog 3 facility. This is designed primarily for convenience of .Xr cron 8 scripts. .It Fl t Ar timeout Specify the maximum time waiting for a server response as the value .Ar timeout , in seconds and fraction. The value is is rounded to a multiple of 0.2 seconds. The default is 1 second, a value suitable for polling across a LAN. .It Fl u Direct .Nm to use an unprivileged port or outgoing packets. This is most useful when behind a firewall that blocks incoming traffic to privileged ports, and you want to synchronise with hosts beyond the firewall. Note that the .Fl d option always uses unprivileged ports. .It Fl v Be verbose.

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. .Nm 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. .Nm 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 compatable 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. .Nm 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 Command line options are described following. Specifying a command line option other than .Op Fl i or .Op 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. .Bl -tag -width indent .It Fl c 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). Multiple .Fl c options may be given. .It Fl i Force .Nm to operate in interactive mode. Prompts will be written to the standard output and commands read from the standard input. .It Fl n Output all host addresses in dotted-quad numeric format rather than converting to the canonical host names. .It Fl p Print a list of the peers known to the server as well as a summary of their state. This is equivalent to the .Ar peers interactive command. .El .Sh INTERNAL COMMANDS 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. 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 `<', followed by a file name, to the command line. A number of interactive format commands are executed entirely within the .Nm program itself and do not result in NTP mode 6 requests being sent to a server. These are described following. .Pp .Bl -tag -width indent .It Cd ? | helpl Op command_keyword .Cd ? by itself will print a list of all the command keywords known to this incarnation of .Nm A .Cd ? followed by a command keyword will print funcation and usage information about the command. This command is probably a better source of information about .Nm than this manual page. .It Cd addvars Ar variable_name Op =value Op ... .It Cd rmvars Ar variable_name Op ... .It Cd clearvars The data carried by NTP mode 6 messages consists of a list of items of the form .Ar variable_name=value , where the .Ar =value is ignored, and can be omitted, in requests to the server to read variables. .Nm maintains an internal list in which data to be included in control messages can be assembled, and sent using the readlist and writelist commands described below. The 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 rmvars command can be used to remove individual variables from the list, while the clearlist command removes all variables from the list. .It Cd authenticate Ar yes | no Normally .Nm does not authenticate requests unless they are write requests. The command authenticate yes causes .Nm to send authentication with all requests it makes. Authenticated requests causes some servers to handle requests slightly differently, and can occasionally melt the CPU in fuzzballs if you turn authentication on before doing a peer display. .It Cd cooked Causes output from query commands to be .Cd cooked . Variables which are recognized by the server will have their values reformatted for human consumption. Variables which .Nm thinks should have a decodeable value but didn't are marked with a trailing .Cd ? . .It Cd debug Ar more | less | off Turns internal query program debugging on and off. .It Cd delay 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. .It Cd host Ar hostname Set the host to which future queries will be sent. Hostname may be either a host name or a numeric address. .It Cd hostnames Op yes | no If .Op yes is specified, host names are printed in information displays. If .Op no is specified, numeric addresses are printed instead. The default is .Op yes , unless modified using the command line .Fl n switch. .It Cd keyid Ar keyid This command allows the specification of a key number to be used to authenticate configuration requests. This must correspond to a key number the server has been configured to use for this purpose. .It Cd ntpversion Ar 1 | 2 | 3 Sets the NTP version number which .Nm claims in packets. Defaults to 3, 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. .It Cd quit Exit .Nm .It Cd 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 Cd raw Causes all output from query commands is printed as received from the remote server. The only formating/intepretation done on the data is to transform nonascii data into a printable (but barely understandable) form. .It Cd timeout Ar millseconds Specify a timeout period for responses to server queries. The default is about 5000 milliseconds. 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. .El .Sh CONTROL MESSAGE COMMANDS Each peer known to an NTP server has a 16 bit integer association identifier assigned to it. NTP control messages which carry peer variables must identify the peer the values correspond to by including its association ID. An association ID of 0 is special, and indicates the variables are system variables, whose names are drawn from a separate name space. .Pp Control message commands result in one or more NTP mode 6 messages being sent to the server, and cause the data returned to be printed in some format. Most commands currently implemented send a single message and expect a single response. The current exceptions are the peers command, which will send a preprogrammed series of messages to obtain the data it needs, and the mreadlist and mreadvar commands, which will iterate over a range of associations. .Bl -tag -width indent .It Cd associations Obtains and prints a list of association identifiers and peer statuses for in-spec peers of the server being queried. The list is printed in columns. The first of these is an index numbering the associations from 1 for internal use, the second the actual association identifier returned by the server and the third the status word for the peer. This is followed by a number of columns containing data decoded from the status word. Note that the data returned by the .Cd associations command is cached internally in .Nm The index is then of use when dealing with stupid servers which use association identifiers which are hard for humans to type, in that for any subsequent commands which require an association identifier as an argument, the form &index may be used as an alternative. .It Cd clockvar Op assocID variable_name =value ... Requests that a list of the server's clock variables be sent. Servers which have a radio clock or other external synchronization will respond positively to this. If the association identifier is omitted or zero the request is for the variables of the .Pa system clock and will generally get a positive response from all servers with a clock. If the server treats clocks as pseudo-peers, and hence can possibly have more than one clock connected at once, referencing the appropriate peer association ID will show the variables of a particular clock. Omitting the variable list will cause the server to return a default variable display. .It Cd lassocations Obtains and prints a list of association identifiers and peer statuses for all associations for which the server is maintaining state. This command differs from the .Cd associations command only for servers which retain state for out-of-spec client associations (i.e., fuzzballs). Such associations are normally omitted from the display when the .Cd associations command is used, but are included in the output of .Cd lassociations . .It Cd lpassociations Print data for all associations, including out-of-spec client associations, from the internally cached list of associations. This command differs from .Cd passociations only when dealing with fuzzballs. .It Cd lpeers Like R peers, except a summary of all associations for which the server is maintaining state is printed. This can produce a much longer list of peers from fuzzball servers. .It Cd mreadlist Ar assocID Ar assocID .It Cd mrl Ar assocID Ar assocID Like the .Cd readlist command, except the query is done for each of a range of (nonzero) association IDs. This range is determined from the association list cached by the most recent .Cd associations command. .It Cd mreadvar Ar assocID assocID Op variable_name=value ... .It Cd mrv Ar assocID assocID Op variable_name=value ... Like the .Cd readvar command, except the query is done for each of a range of (nonzero) association IDs. This range is determined from the association list cached by the most recent .Cd associations command. .It Cd opeers An old form of the .Cd peers command with the reference ID replaced by the local interface address. .It Cd passociations Prints association data concerning in-spec peers from the internally cached list of associations. This command performs identically to the .Cd associations except that it displays the internally stored data rather than making a new query. .It Cd peers Obtains a list of in-spec peers of the server, along with a summary of each peer's state. Summary information includes the address of the remote peer, the reference ID (0.0.0.0 if the refID is unknown), the stratum of the remote peer, the type of the peer (local, unicast, multicast or broadcast), when the last packet was received, the polling interval, in seconds, the reachability register, in octal, and the current estimated delay, offset and dispersion of the peer, all in seconds. .Pp The character in the left margin indicates the fate of this peer in the clock selection process. The codes mean: .Cd "\ " discarded due to high stratum and/or failed sanity checks; .Cd "x" designated falseticker by the intersection algorithm; .Cd "." culled from the end of the candidate list; .Cd "-" discarded by the clustering algorithm; .Cd "+" included in the final selection set; .Cd "#" selected for synchronization but distance exceeds maximum; .Cd "*" selected for synchronization; and .Cd "o" selected for synchronization, PPS signal in use. .Pp Note that since the peers command depends on the ability to parse the values in the responses it gets it may fail to work from time to time with servers which poorly control the data formats. .Pp The contents of the host field may be one of four forms. It may be a host name, an IP address, a reference clock implementation name with its parameter or .Cd "REFCLK(,)" . On .Cd "hostnames no" only IP-addresses will be displayed. .It Cd pstatus Ar assocID Sends a read status request to the server for the given association. The names and values of the peer variables returned will be printed. Note that the status word from the header is displayed preceding the variables, both in hexidecimal and in pidgeon English. .It Cd readlist Op assocID .It Cd rl Op assocID Requests that the values of the variables in the internal variable list be returned by the server. If the association ID is omitted or is 0 the variables are assumed to be system variables. Otherwise they are treated as peer variables. If the internal variable list is empty a request is sent without data, which should induce the remote server to return a default display. .It Cd readvar Ar assocID Op variable_name=value ... .It Cd rv Ar assocID Op variable_name=value ... Requests that the values of the specified variables be returned by the server by sending a read variables request. If the association ID is omitted or is given as zero the variables are system variables, otherwise they are peer variables and the values returned will be those of the corresponding peer. Omitting the variable list will send a request with no data which should induce the server to return a default display. .It Cd writevar Ar assocID Op variable_name=value ... Like the readvar request, except the specified variables are written instead of read. .It Cd writelist Op assocID Like the readlist request, except the internal list variables are written instead of read. .El .Sh BUGS The peers command is non-atomic and may occasionally result in spurious error messages about invalid associations occurring and terminating the command. The timeout time is a fixed constant, which means you wait a long time for timeouts since it assumes sort of a worst case. The program should improve the timeout estimate as it sends queries to a particular host, but doesn't. .Pp .Sh FILES .Bl -tag -width /etc/ntp.keys -compact .It Pa /usr/share/doc/xntp/index.html .It Pa /usr/share/doc/xntp/ntpq.html. .Sh AUTHOR David L.

While the ultimate precision of this design, about 232 picoseconds, is not achievable with ordinary workstations and networks of today, it may be required with future nanosecond CPU clocks and gigabit LANs. .Pp The daemon can operate in any of several modes, including symmetric active/passive, client/server and broadcast/multicast, as described in RFC-1305. A broadcast/multicast client can discover remote servers, compute server-client propagation delay correction factors and configure itself automatically. This makes it possible to deploy a fleet of workstations without specifying configuration details specific to the local environment. .Pp Ordinarily, .Nm reads the .Pa ntp.conf configuration file at startup time in order to determine the synchronization sources and operating modes. It is also possible to specify a working, although limited, configuration entirely on the command line, obviating the need for a configuration file. This may be particularly appropriate when the local host is to be configured as a broadcast or multicast client, with all peers being determined by listening to broadcasts at run time. .Pp Various internal .Nm variables can be displayed and configuration options altered while the daemon is running using the .Xr ntpq 8 and .Xr xntpdc 8 utility programs. .Pp When .Nm starts it looks at the value of .Pa umask , and if it's zero .Nm will set .Pa umask to .Pa 022 . .Pp The options are as follows: .Bl -tag -width indent .It Fl a Enable authentication mode. The default is enabled, so this option is obsolete now. .It Fl A Disable authentication mode. .It Fl b Synchronize using NTP broadcast messages. .It Fl c Ar conffile Specify the name and path of the configuration file. .It Fl d Specify debugging mode. This flag may occur multiple times, with each occurrence indicating greater detail of display. .It Fl f Ar driftfile Specify the name and path of the drift file. .It Fl k Ar keyfile Specify the name and path of the file containing the NTP authentication keys. .It Fl l Ar logfile Specify the name and path of the log file. The default is the system log facility. .It Fl m Synchronize using NTP multicast messages on the IP multicast group address 224.0.1.1 (requires multicast kernel). .It Fl p Ar pidfile Specify the name and path to record the daemon's process ID. .It Fl r Ar broadcastdelay Specify the default propagation delay from the broadcast/multicast server and this computer. This is used only if the delay cannot be computed automatically by the protocol. .It Fl s Ar statsdir Specify the directory path for files created by the statistics facility. .It Fl t Ar key Add a key number to the trusted key list. .It Fl v Ar variable Add a system variable. .It Fl V Ar variable Add a system variable listed by default. .El .Pp .Sh THE CONFIGURATION FILE The .Nm configuration file is read at initial startup in order to specify the synchronization sources, modes and other related information. Usually, it is installed in the .Pa /etc directory, but could be installed elsewhere (see the .Fl -c Ar conffile command line option). The file format is similar to other Unix configuration files - comments begin with a .Pa # character and extend to the end of the line; blank lines are ignored. Configuration commands consist of an initial keyword followed by a list of arguments, some of which may be optional, separated by whitespace. Commands may not be continued over multiple lines. Arguments may be host names, host addresses written in numeric, dotted-quad form, integers, floating point numbers (when specifying times in seconds) and text strings. Optional arguments are delimited by .Pa [ ] in the following descriptions, while alternatives are separated by .Pa | . The notation [ ... ] means an optional, indefinite repetition of the last item before the [ ... ]. .Pp See the following pages for configuration and control options. While there is a rich set of options available, the only required option is one or more .Pa server, peer or .Pa broadcast commands described in the .Pa Configuration Options page. The .Pa Notes on Configuring NTP and Setting up a NTP Subnet page contains an extended discussion of these options. .\" XXX .\"

Thorpe .Dd April 17, 1997 .Dt XNTPDC 8 .Os NetBSD .Sh NAME .Nm xntpdc .Nd special NTP query program .Sh SYNOPSIS .Nm .Op Fl ilnps .Op Fl c Ar command .Oo .Ar host Oo ... .Oc .Oc .Sh DESCRIPTION .Nm is used to query the .Xr xntpd 8 daemon about its current state and to request changes in that state. The program may be run either in interactive mode or controlled using command line arguments. Extensive state and statistics information is available through the .Nm interface. In addition, nearly all the configuration options which can be specified at start up using xntpd's configuration file may also be specified at run time using .Nm .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. .Nm will prompt for commands if the standard input is a terminal device. .Pp .Nm uses NTP mode 7 packets to communicate with the NTP server, and hence can be used to query any compatable 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. .Nm makes no attempt to retransmit requests, and will time requests out if the remote host is not heard from within a suitable timeout time. .Pp The operation of .Nm are specific to the particular implementation of the .Xr xntpd 8 daemon and can be expected to work only with this and maybe some previous versions of the daemon. Requests from a remote .Nm program which affect the state of the local server must be authenticated, which requires both the remote program and local server share a common key and key identifier. .Pp The options are as follows: .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. .Bl -tag -width indent .It Fl c Ar command 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). Multiple .Fl c options may be given. .It Fl i Force .Nm to operate in interactive mode. Prompts will be written to the standard output and commands read from the standard input. .It Fl l Obtain a list of peers which are known to the server(s). This switch is equivalent to .Fl c Ar listpeers . .It Fl n Output all host addresses in dotted-quad numeric format rather than converting to the canonical host names. .It Fl p Print a list of the peers known to the server as well as a summary of their state. This is equivalent to .Fl c Ar peers . .It Fl s Print a list of the peers known to the server as well as a summary of their state, but in a slightly different format than the .Fl p switch. This is equivalent to .Fl c Ar dmpeers . .El .Pp .Sh INTERACTIVE COMMANDS 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. 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 .\" XXX I don't think this is right, but it's what the HTML said... --thorpej .Pa < , followed by a file name, to the command line. .Pp A number of interactive format commands are executed entirely within the .Nm program itself and do not result in NTP mode 7 requests being sent to a server. These are described following. .Bl -tag -width indent .It ? Op Ar command_keyword .It help Op Ar command_keyword A .Pa ? by itself will print a list of all the command keywords known to this incarnation of .Xr ntpq 8 . A .Pa ? followed by a command keyword will print funcation and usage information about the command. This command is probably a better source of information about .Nm ntpq than this manual page. .It delay 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. .It host Ar hostname Set the host to which future queries will be sent. Hostname may be either a host name or a numeric address. .It hostname Op Ar yes | no If .Ar yes is specified, host names are printed in information displays. If .Ar no is specified, numeric addresses are printed instead. The default is .Ar yes , unless modified using the command line .Fl n switch. .It keyid Ar keyid This command allows the specification of a key number to be used to authenticate configuration requests. This must correspond to a key number the server has been configured to use for this purpose. .It quit Exit .Nm .It 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 timeout Ar milliseconds Specify a timeout period for responses to server queries. The default is about 8000 milliseconds. 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. .El .Pp .Sh CONTROL MESSAGE COMMANDS Query commands result in NTP mode 7 packets containing requests for information being sent to the server. These are read-only commands in that they make no modification of the server configuration state. .Bl -tag -width indent .It listpeers Obtains and prints a brief list of the peers for which the server is maintaining state. These should include all configured peer associations as well as those peers whose stratum is such that they are considered by the server to be possible future synchonization candidates. .It peers Obtains a list of peers for which the server is maintaining state, along with a summary of that state. Summary information includes the address of the remote peer, the local interface address (0.0.0.0 if a local address has yet to be determined), the stratum of the remote peer (a stratum of 16 indicates the remote peer is unsynchronized), the polling interval, in seconds, the reachability register, in octal, and the current estimated delay, offset and dispersion of the peer, all in seconds. In addition, the character in the left margin indicates the mode this peer entry is operating in. A .Pa + denotes symmetric active, a .Pa - indicates symmetric passive, a .Pa = means the remote server is being polled in client mode, a .Pa ^ indicates that the server is broadcasting to this address, a .Pa ~ denotes that the remote peer is sending broadcasts and a .Pa * marks the peer the server is currently synchonizing to. .Pp The contents of the host field may be one of four forms. It may be a host name, an IP address, a reference clock implementation name with its parameter or .Pa REFCLK(implementation number, parameter) . On .Pa hostnames no only IP-addresses will be displayed. .It dmpeers A slightly different peer summary list. Identical to the output of the .Pa peers command, except for the character in the leftmost column. Characters only appear beside peers which were included in the final stage of the clock selection algorithm. A .Pa . indicates that this peer was cast off in the falseticker detection, while a .Pa + indicates that the peer made it through. A .Pa * denotes the peer the server is currently synchronizing with. .It showpeer Ar peer_address Op Ar ... Shows a detailed display of the current peer variables for one or more peers. Most of these values are described in the NTP Version 2 specification. .It pstats Ar peer_address Op Ar ... Show per-peer statistic counters associated with the specified peer(s). .It clockinfo clock_peer_address Op Ar ... Obtain and print information concerning a peer clock. The values obtained provide information on the setting of fudge factors and other clock performance information. .It kerninfo Obtain and print kernel phase-lock loop operating parameters. This information is available only if the kernel has been specially modified for a precision timekeeping function. .It loopinfo Op Ar oneline | multiline Print the values of selected loop filter variables. The loop filter is the part of NTP which deals with adjusting the local system clock. The .Pa offset is the last offset given to the loop filter by the packet processing code. The .Pa frequency is the frequency error of the local clock in parts-per-million (ppm). The .Pa time_const controls the stiffness of the phase-lock loop and thus the speed at which it can adapt to oscillator drift. The .Pa watchdog timer value is the number of seconds which have elapsed since the last sample offset was given to the loop filter. The .Ar oneline and .Ar multiline options specify the format in which this information is to be printed, with .Ar multiline as the default. .It sysinfo Print a variety of system state variables, i.e., state related to the local server. All except the last four lines are described in the NTP Version 3 specification, RFC-1305. .Pp The .Pa system flags show various system flags, some of which can be set and cleared by the .Pa enable and .Pa disable configuration commands, respectively. These are the .Pa auth , .Pa bclient , .Pa monitor , .Pa pll , .Pa pps and .Pa stats flags. See the .Xr xntpd 8 documentation for the meaning of these flags. There are two additional flags which are read only, the .Pa kernel_pll and .Pa kernel_pps . These flags indicate the synchronization status when the precision time kernel modifications are in use. The .Pa kernel_pll indicates that the local clock is being disciplined by the kernel, while the kernel_pps indicates the kernel discipline is provided by the PPS signal. .Pp The .Pa stability is the residual frequency error remaining after the system frequency correction is applied and is intended for maintenance and debugging. In most architectures, this value will initially decrease from as high as 500 ppm to a nominal value in the range .01 to 0.1 ppm. If it remains high for some time after starting the daemon, something may be wrong with the local clock, or the value of the kernel variable .Pa tick may be incorrect. .Pp The .Pa broadcastdelay shows the default broadcast delay, as set by the .Pa broadcastdelay configuration command. .Pp The .Pa authdelay shows the default authentication delay, as set by the .Pa authdelay configuration command. .Pp .It sysstats Print statistics counters maintained in the protocol module. .It memstats Print statistics counters related to memory allocation code. .It iostats Print statistics counters maintained in the input-output module. .It timerstats Print statistics counters maintained in the timer/event queue support code. .It reslist Obtain and print the server's restriction list. This list is (usually) printed in sorted order and may help to understand how the restrictions are applied. .It monlist Op Ar version Obtain and print traffic counts collected and maintained by the monitor facility. The version number should not normally need to be specified. .It clkbug Ar clock_peer_address Op Ar ... Obtain debugging information for a reference clock driver. This information is provided only by some clock drivers and is mostly undecodable without a copy of the driver source in hand. .El .Pp .Sh RUNTIME CONFIGURATION REQUESTS All requests which cause state changes in the server are authenticated by the server using a configured NTP key (the facility can also be disabled by the server by not configuring a key). The key number and the corresponding key must also be made known to .Nm xtnpdc . This can be done using the .Pa keyid and .Pa passwd commands, the latter of which will prompt at the terminal for a password to use as the encryption key. You will also be prompted automatically for both the key number and password the first time a command which would result in an authenticated request to the server is given. Authentication not only provides verification that the requester has permission to make such changes, but also gives an extra degree of protection again transmission errors. .Pp Authenticated requests always include a timestamp in the packet data, which is included in the computation of the authentication code. This timestamp is compared by the server to its receive time stamp. If they differ by more than a small amount the request is rejected. This is done for two reasons. First, it makes simple replay attacks on the server, by someone who might be able to overhear traffic on your LAN, much more difficult. Second, it makes it more difficult to request configuration changes to your server from topologically remote hosts. While the reconfiguration facility will work well with a server on the local host, and may work adequately between time-synchronized hosts on the same LAN, it will work very poorly for more distant hosts. As such, if reasonable passwords are chosen, care is taken in the distribution and protection of keys and appropriate source address restrictions are applied, the run time reconfiguration facility should provide an adequate level of security. .Pp The following commands all make authenticated requests. .Bl -tag -width indent .It addpeer Ar peer_address Op keyid version prefer Add a configured peer association at the given address and operating in symmetric active mode. Note that an existing association with the same peer may be deleted when this command is executed, or may simply be converted to conform to the new configuration, as appropriate. If the optional .Ar keyid is a nonzero integer, all outgoing packets to the remote server will have an authentication field attached encrypted with this key. If the value is 0 (or not given) no authentication will be done. The .Ar version can be 1, 2 or 3 and defaults to 3. The .Ar prefer keyword indicates a preferred peer (and thus will be used primarily for clock synchronisation if possible). The preferred peer also determines the validity of the PPS signal - if the preferred peer is suitable for synchronisation so is the PPS signal. .It addserver Ar peer_address Op keyid version prefer Identical to the .Pa addpeer command, except that the operating mode is client. .It broadcast Ar peer_address keyid version prefer Identical to the addpeer command, except that the operating mode is broadcast. In this case a valid key identifier and key are required. The .Ar peer_address parameter can be the broadcast address of the local network or a multicast group address assigned to NTP. If a multicast address, a multicast-capable kernel is required. .It unconfig Ar peer_address Op Ar ... This command causes the configured bit to be removed from the specified peer(s). In many cases this will cause the peer association to be deleted. When appropriate, however, the association may persist in an unconfigured mode if the remote peer is willing to continue on in this fashion. .It fudge Ar peer_address Op time1 time2 stratum refid This command provides a way to set certain data for a reference clock. See the source listing for further information. .It enable Op flag ... .It disable Op Ar flag Op Ar ... These commands operate in the same way as the .Pa enable and .Pa disable configuration file commands of .Xr xntpd 8 . Following is a description of the flags. Note that only the .Pa auth , .Pa bclient , .Pa monitor , .Pa pll , .Pa pps and .Pa stats flags can be set by .Nm the .Pa pll_kernel and .Pa pps_kernel flags are read-only. .Pp .Pa auth Enables the server to synchronize with unconfigured peers only if the peer has been correctly authenticated using a trusted key and key identifier. The default for this flag is enable. .Pp .Pa bclient Enables the server to listen for a message from a broadcast or multicast server, as in the .Pa multicastclient command with default address. The default for this flag is disable. .Pp .Pa monitor Enables the monitoring facility. See the .Xr xntpdc 8 program and the .Pa monlist command or further information. The default for this flag is enable. .Pp .Pa pll Enables the server to adjust its local clock by means of NTP. If disabled, the local clock free-runs at its intrinsic time and frequency offset. This flag is useful in case the local clock is controlled by some other device or protocol and NTP is used only to provide synchronization to other clients. In this case, the local clock driver is used. See the .Pa Reference Clock Drivers page for further information. The default for this flag is enable. .Pp .Pa pps Enables the pulse-per-second (PPS) signal when frequency and time is disciplined by the precision time kernel modifications. See the .Pa A Kernel Model for Precision Timekeeping page for further information. The default for this flag is disable. .Pp .Pa stats Enables the statistics facility. See the .Pa Monitoring Options page for further information. The default for this flag is enable. .Pp .Pa pll_kernel When the precision time kernel modifications are installed, this indicates the kernel controls the clock discipline; otherwise, the daemon controls the clock discipline. .Pp .Pa pps_kernel When the precision time kernel modifications are installed and a pulse-per-second (PPS) signal is available, this indicates the PPS signal controls the clock discipline; otherwise, the daemon or kernel controls the clock discipline, as indicated by the .Pa pll_kernel flag. .It restrict Ar address mask flag Op Ar flag This command operates in the same way as the .Pa restrict configuration file commands of .Xr xntpd 8 . .It unrestrict Ar address mask flag Op Ar flag Unrestrict the matching entry from the restrict list. .It delrestrict Ar address mask Op Ar ntpport Delete the matching entry from the restrict list. .It readkeys Causes the current set of authentication keys to be purged and a new set to be obtained by rereading the keys file (which must have been specified in the .Xr xntpd 8 configuration file). This allows encryption keys to be changed without restarting the server. .It trustkey Ar keyid Op Ar ... .It untrustkey Ar keyid Op Ar ... These commands operate in the same way as the .Pa trustedkey and .Pa untrustkey configuration file commands of .Xr xntpd 8 . .It authinfo Returns information concerning the authentication module, including known keys and counts of encryptions and decryptions which have been done. .It traps Display the traps set in the server. See the source listing for further information. .It addtrap Op Ar address Op port interface Set a trap for asynchronous messages. See the source listing for further information. .It clrtrap Op Ar address Op port interface Clear a trap for asynchronous messages. See the source listing for further information. .It reset Clear the statistics counters in various modules of the server. See the source listing for further information. .El .Sh BUGS .Nm is a crude hack. Much of the information it shows is deadly boring and could only be loved by its implementer. The program was designed so that new (and temporary) features were easy to hack in, at great expense to the program's ease of use. Despite this, the program is occasionally useful. .Pp .Sh FILES .Bl -tag -width /etc/ntp.keys -compact .It Pa /usr/share/doc/xntp/index.html .It Pa /usr/share/doc/xntp/xntpdc.html .El .Sh AUTHOR David L.
