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. xntpd directory containing sources for the NTP Version 3 daemon. 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.
