The xntp3 Distribution
|
|
|
|
This directory and its subdirectories contain the Network Time Protocol
|
|
Version 3 (NTP) distribution for Unix systems. It contains source code
|
|
for the daemon, together with related auxiliary programs, documentation
|
|
and strange stuff. You are welcome to the lot, with due consideration of
|
|
the COPYRIGHT files stashed in the distributions. You are also invited
|
|
to contribute bugfixes and drivers for new and exotic radios, telephones
|
|
and sundials. This distribution is normally available by anonymous ftp
|
|
as the compressed tar archive xntp-<version>.tar.Z in the pub/ntp directory
|
|
on louie.udel.edu.
|
|
|
|
The base directory contains the distributions and related stuff. The files
|
|
marked with a "*" are not distributed, but generated. Most of
|
|
the subdirectories contain README files describing their contents. The
|
|
base directory ./ includes:
|
|
|
|
COPYRIGHT file specifying copyright conditions, together with a
|
|
list of major authors and electric addresses.
|
|
|
|
Config * configuration file built by the configuration script
|
|
"make makeconfig" and used to build the makefiles in the
|
|
various subdirectories. Do not edit.
|
|
|
|
Config.local * Unless you have a reference clock (besides the local
|
|
computer clock) or want to change the default installation
|
|
directory (/usr/local/bin) not action is needed. For
|
|
configuring a reference clock a "make refconf" should
|
|
suffice. Diehards can still use an editor on this file.
|
|
|
|
Config.local.dist file used to generate a plausible Config.local by commands
|
|
such as "make Config.local.green".
|
|
|
|
Config.sed * sed script used to build makefiles from the
|
|
configuration file. Do not edit.
|
|
|
|
Makefile this is the root of the makefile tree. Do not edit.
|
|
(Contents under pressure - qualified personel only 8-)
|
|
|
|
PORTING contains useful information for porting to unexplored
|
|
new systems.
|
|
|
|
RELNOTES instructions for compiling and installing the daemon and
|
|
supporting programs.
|
|
|
|
README this file.
|
|
|
|
TODO our current problems where we could need help.
|
|
|
|
adjtime directory containing the sources for the adjtime daemon
|
|
for HP/UX systems.
|
|
|
|
authstuff directory containing sources for miscellaneous programs
|
|
to test, calibrate and certify the cryptographic
|
|
mechanisms for DES and MD5 based authentication. These
|
|
programs do not include the cryptographic routines
|
|
themselves, so are free of U.S. export restrictions.
|
|
|
|
clockstuff directory containing sources for miscellaneous programs
|
|
to test certain auxilliary programs used with some
|
|
kernel configurations, together with a program to
|
|
calculate propagation delays for use with radio clocks
|
|
and national time dissemination services such as
|
|
WWV/WWVH, WWVB and CHU.
|
|
|
|
compilers directory containing configuration scripts for various
|
|
compilers and operating systems.
|
|
|
|
conf directory containing a motley collection of
|
|
configuration files for various systems. For example
|
|
only.
|
|
|
|
doc directory containing miscellaneous man pages and memos
|
|
useful for installation and subnet management.
|
|
|
|
gadget directory containing instructions and construction data
|
|
for a mysterious little box used as a CHU radio
|
|
demodulator and/or a level converter-pulse generator for
|
|
a precision 1-pps signal.
|
|
|
|
include directory containing include header files used by most
|
|
programs in the distribution.
|
|
|
|
hints directory containing files with hints on particular
|
|
topics like installation on specific OS variants or
|
|
general information.
|
|
|
|
kernel directory containing sources for kernel programs such as
|
|
line disciplines and STREAMS modules used with the CHU
|
|
decoder and precision 1-pps signals.
|
|
|
|
lib directory containing sources for the library programs
|
|
used by most programs in the distribution.
|
|
|
|
machines directory containing configuration scripts for various
|
|
operating systems.
|
|
|
|
ntpdate directory containing sources for a program to set the
|
|
local machine time from one or more remote machines
|
|
running NTP. Operates like rdate, but much more
|
|
accurate.
|
|
|
|
ntpq directory containing sources for a utility program to
|
|
query local and remote NTP peers for state variables and
|
|
related timekeeping information. This program conforms
|
|
to Appendix A of the NTP Version 3 Specification RFC
|
|
1305.
|
|
|
|
ntptrace directory containing sources for a utility program that
|
|
can be used to reveal the chain of NTP peers from a
|
|
designated peer to the primary server at the root of the
|
|
timekeeping subnet.
|
|
|
|
parse directory containing file belonging to the generic parse
|
|
reference clock driver. For reasonably simple clocks it
|
|
is possible to get away with about 3-4Kb of code.
|
|
additionally the SunOS 4.x streams module for parse is
|
|
residing here.
|
|
|
|
parse/util some goodies for testing parse processing of DCF77 information.
|
|
(primarily for use on Suns, although others may work
|
|
also - possibly with a little porting.)
|
|
one little gem is dcfd.c - DCF77 decoder with ntp loopfilter
|
|
code for standalone DCF77 synchronisation without the full
|
|
works of NTP.
|
|
Dcfd.c has been ported to FreeBSD for the Boeder DCF77 receiver
|
|
by Vincenzo Capuano.
|
|
|
|
ppsclock directory containing sources for modifications to the
|
|
kernel asynchronous serial driver plus a STREAMS module
|
|
to capture a precision 1-pps signal. Useful on SunOS
|
|
4.1.X systems only.
|
|
|
|
refclocks directory containing reference clock configuration support
|
|
|
|
scripts directory containing scripts to build the configuration
|
|
file "config" in this directory and then the makefiles
|
|
used in various dependent directories.
|
|
the subdirectories monitoring and support hold various
|
|
perl and shell scripts for visualising synchronisation
|
|
and daemon startup.
|
|
|
|
util directory containing sources for various utility and
|
|
testing programs.
|
|
|
|

|
|
|
|
xntpdc directory containing sources for a utility program to
|
|
query local and remote NTP peers for state variables and
|
|
related timekeeping information. This program is
|
|
specific to this implmentation of NTP Version 3 and does
|
|
not conform to Appendix A of the NTP Version 3
|
|
Specification RFC 1305.
|
|
|
|
xntpres directory containing sources for a name-resolution
|
|
program used in some configurations of NTP Version 3.
