The ntp Directory
This directory and its subdirectories contain the various distributions
of the Network Time Protocol (NTP), together with related auxilliary
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.
The base directory ~ntp/pub/ntp contains the distributions and related
stuff, including:
msctime.tar.Z compressed tar archive containing the NBS Automated
Comuter Time Service software, ported to Microsoft C for
IBM PC and Unix C for Sun workstations
nbstime.tar.Z compressed tar archive containing the NBS Automated
Comuter Time Service software, as distributed by NBS
ntp.3.4 subdirectory containing the NTP Version 1 daemon for
Unix written by Michael Petry and Louis Mamakos of the
University of Maryland. Not recommended for new
installations.
xntp subdirectory containing the NTP Version 2 daemon for
Unix written by Dennis Fergusson of the University of
Toronto. Not recoommended for new installations.
xntp3.tar.Z compressed tar archive containing the NTP Version 3
daemon for Unix adapted from the version-3 daemon by
Lars Mathiesen of the University of Copenhagen and many
of his friends. Restricted for use in the US and Canada.
xntp3.export.tar.Z compressed tar archive containing the NTP Version 3
daemon for Unix adapted from the version-3 daemon by
Lars Mathiesen of the University of Copenhagen and many
of his friends. Unrestricted distribution. Requires a
software implementation of the Data Encryption Standard
readily available outside the U.S. and Canada.
loran.tar.Z compressed tar archive containing the schematics,
artwork and documentation for a computer-controlled
LORAN-C timing receiver used as a precision source of
standard time. Not recommended for beginners.
gadget.tar.Z compressed tar archive containing the schematics,
artwork and related information for (a) a modem for the
Canadian time/frequency radio service CHU, which can be
used as a primary reference clock for NTP Version 2 and
Version 3 daemons, and (b) a pulse shaper and line
driver used to provide an external one-pulse-per-second
signal from a radio clock to a serial port.
minimuf.c, gain.dat program in C and data file in ascii for a program
that computes high frequency radio propagation data and
delays between two geographic locations on the Earth.
This is intended for use in setting propagation-delay
switches on radio clocks.
jaguar.txt.Z Job description for a Maya high priest taken from the
Book of Chillum Balum. Useful for after-dinner rallies
and cheerleaders.
info.txt.Z compressed file containing useful hints and kinks on
setting up NTP service
The doc subdirectory includes a number of compressed files containing
papers, rfcs and technical reports on NTP. Those with names ending in
*.ps.Z are in PostScript, while the others are in ascii. When the same
document is displayed with *.ps.Z and *.txt.Z extension, the latter
version is an ascii-greppable file that may not violate the Principle of
Least Astonishment with respect to the former version; however, much is
lost in translation.
bishop.ps.Z compressed file containing a draft of a report by Matt
Bishop discussing security issues in NTP
bone.ps.Z compressed file containing a paper on the NSFnet Phase-I
Backbone Network, in which NTP played a prominent part.
Of historic interest.
Mills, D.L., and H.-W. Braun. The NSFNET Backbone
Network. Proc. ACM SIGCOMM 87 Symposium (Stoweflake
Vermont, August 1987), 191-196.

practice and experience operating NTP in the global
Internet

synchronized by the Network Time Protocol in the
Internet system. ACM Computer Communication Review 20, 1
(January 1990), 65-75.
clock.txt ascii file containing (a) a list of primary (stratum 1)
servers operating in the Internet, (b) a list of
secondary (stratum 2) servers operating in the Internet,
(c) a list of known radio timecode receivers along with
addresses and phone numbers of the suppliers, (d) bits
of riffraff information that defy classification. This
file is updated on a haphazard basis at irregular
intervals.
dts.txt.Z, dtsrev.txt.Z compressed files containing unpublished message
digests comparing NTP and the Digital Time
Synchronization Service (DTSS). Note: this is an
informal discussion and should not be quoted or
extracted from context, even with attribution.
fuzz.ps.Z compressed file for a paper describing the infamous
Fuzzball operating system and culture for the PDP11 and
relatives. When the last fuzzball dies, this will be of
historic interest only.

(Palo Alto, California, August 1988), 115-122.
ndp.ps.Z, ndp.txt.Z compressed files for an unpublished technical
memorandum comparing NTP and the Digital Time
Synchronization Service (DTSS). Note: this memorandum is
intended for professional use only and may not be cited
or excerpted without the consent of the author.
