Submit patches, bug reports, and enhancement requests via http://bugs.ntp.org The ntp Distribution Base Directory This directory and its subdirectories contain the Network Time Protocol Version 4 (NTP) distribution for Unix and Windows/NT systems. This release may still work on VxWorks, too. The contents of the base directory are given in this file. The contents of subdirectories are given in the README files in each subdirectory. A complete explanation of the configure, compile and install process, as well as setting up an NTP subnet, is in the HTML pages in the ./html/ directory. For more information on NTP and how to get a working setup, read WHERE-TO-START. For Windows/NT, visit html/build/hints/winnt.html . The base directory ./ contains the autoconfiguration files, source directories and related stuff: COPYRIGHT Excerpt from the HTML file ./html/copyright.html. This file specifies copyright conditions, together with a list of major authors and electric addresses. INSTALL Generic installation instructions for autoconf-based programs. Unless you really know what you are doing, you should read the directions in the HTML pages, starting with ./html/index.html. NEWS What's new in this release. README This file. README.bk Instructions for folks who use the BitKeeper-repository version of NTP. README.hackers Notes to folks who want to hack on the code. TODO List of items the NTP developers are working on. WHERE-TO-START Hints on what to read in order to get a working configuration. Makefile.am Automake file configuration file. Edit only if you have the GNU automake and autoconf utilities installed. Makefile.in Autoconf make file template for Unix. adjtimed Directory containing the sources for the adjtime daemon for HP/UX systems prior to HP-UX 10.0. 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. build A script to build the distribution in A.`config.guess` subdirectory (more or less). clockstuff Directory containing sources for miscellaneous programs to test certain auxiliary 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. conf Directory containing a motley collection of configuration files for various systems. For example only. config.guess Script used to identify the machine architecture and operating system. config.h.in Configuration file generated automatically from configure.in. Do not edit. configure Script used to configure the distribution. See the HTML pages (./html/index.html) for a complete description of the options available. configure.in Master configuration template. Edit only if you have the GNU automake and autoconf utilities installed. dot.emacs C-mode indentation rules for code "Just the way Dave likes it". flock_build (UDel only) Build the distribution on a number of different platforms. html Directory containing a complete set of documentation on building and configuring a NTP server or client. The documentation is in the form of HTML files suitable for browsing and contains links to additional documentation at various web sites. If a browser is unavailable, an ordinary text editor can be used. include Directory containing include header files used by most programs in the distribution. install-sh Script to install a program, script or data file. kernel Directory containing sources for kernel programs such as line disciplines and STREAMS modules used with the CHU decoder and precision PPS signals. libntp Directory containing library source code used by most programs in the distribution. 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 files 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/Solaris 5.3 streams module for parse squats here. patches Directory containing patches already applied to this distribution. These are included for record and to help in possible porting problems. scripts Directory containing scripts to build the configuration files in this directory and then the makefiles used in various dependent directories. the subdirectories monitoring and support hold various perl and shell scripts for visualizing synchronization and daemon startup. stamp.h.in Configuration file generated automatically from configure.in. Do not edit. util Directory containing sources for various utility and testing programs. David L. Mills (mills@udel.edu) 21 June 1998
