ntpd

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. The base directory ./ contains the autoconfiguration files, source directories and related stuff: 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. Makefile.am Automake file configuration file. Edit only if you have the GNU automake and autoconf utilities installed. 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. 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. 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. include Directory containing include header files used by most programs in the distribution. 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.
