|
|
# Perl script to convert a standard distribution directory for xntp into
|
|
# a NetBSD source tree.
|
|
#
|
|
# This is done as a script so that as each distribution is released,
|
|
# only changes from the previous one need to be dealt with as
|
|
# modifications to this script and related files. This should
|
|
# reduce the cost of updating from a new release of xntp by an
|
|
# order of magnitude (or more?)
|
|
#
|
|
# This script requires two environment variables set:
|
|
# SRCDIR - gcc source directory from FSF
|
|
# TARGETDIR - name of the high level directory to make
|
|
#
|
|
# Written by Christos Zoulas April 17, 1997 for xntp 3-5.90

.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. This option will cause the
|
|
.Nm
|
|
version
|
|
identification string to be logged.

.Sh BUGS
|
|
The slew adjustment is actually 50% larger than the measured offset,
|
|
since this (it is argued) will tend to keep a badly drifting clock more
|
|
accurate. This is probably not a good idea and may cause a troubling
|
|
hunt for some values of the kernel variables
|
|
.Xr tick 9
|
|
and
|
|
.Xr tickadj 9 .

|

.Sh DESCRIPTION
|
|
.Nm
|
|
is used to query NTP servers which implement the
|
|
recommended NTP mode 6 control message format about current state and to
|
|
request 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.
|
|
.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(<implementation number>,<parameter>)" .
|
|
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.

|
|
.Nm
|
|
determines where a given Network Time Protocol
|
|
(NTP) server gets its time from, and follows the chain of NTP servers
|
|
back to their master time source. If given no arguments, it starts with
|
|
.Pa localhost
|
|
Here is an example of the output from
|
|
.Nm
|
|
.nf
|
|
% ntptrace
|
|
localhost: stratum 4, offset 0.0019529, synch distance 0.144135
|
|

|
|
usndh.edu: stratum 1, offset 0.00192, synch distance 0.011, refid 'WWVB'
|
|
.fi
|
|
.Pp
|
|
On each line, the fields are (left to right): the host name, the host
|
|
stratum, the time offset between that host and the local host (as
|
|
measured by
|
|
.Nm
|
|
this is why it is not always zero for
|
|
.Pa localhost,
|
|
the host synchronization distance, and (only
|
|
for stratum-1 servers) the reference clock ID. All times are given in
|
|
seconds. Note that the stratum is the server hop count to the primary
|
|
source, while the synchronization distance is the estimated error
|
|
relative to the primary source. These terms are precisely defined in
|
|
RFC-1305.
|

|
|
Turns on some debugging output.
|
|
.It Fl n
|
|
Turns off the printing of host names; instead, host IP addresses are
|
|
given. This may be useful if a nameserver is down.
|
|
.It Fl r Ar retries
|
|
Sets the number of retransmission attempts for each host (default = 5).
|
|
.It Fl t Ar timeout
|
|
Sets the retransmission timeout (in seconds) (default = 2).
|
|
.It Fl v
|
|
Prints verbose information about the NTP servers.

.Sh DESCRIPTION
|
|
.Nm
|
|
is an operating system daemon which sets and
|
|
maintains the system time-of-day in synchronism with Internet
|
|
standard time servers.
|
|
.Nm
|
|
is a complete
|
|
implementation of the Network Time Protocol (NTP) version 3, as
|
|
defined by RFC-1305, but also retains compatibility with version 1
|
|
and 2 servers as defined by RFC-1059 and RFC-1119,
|
|
respectively.
|
|
.Nm
|
|
does all computations in 64-bit
|
|
fixed point arithmetic and requires no floating point
|
|
support. 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.
|

.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
|

|
.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.

|
|
source of information about

|
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
