This directory contains NTP documents/drivers/programs. (NTP - Network Time Protocol) Latest programs/docs can be found on louie.udel.edu subdirectory which is mirror from louie.udel.edu. So if you are from states, please use louie.udel.edu directly... Most of files in this directory (/pub/unix/tcpip/ntp) are rather old so you really should check first if you can locate the files you want under louie.udel.edu directory. Hannu Martikka goodgulf@nic.funet.fi - Very old README from louie---------------------------------------------- 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 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. ccr.ps.Z, ccr.txt.Z compressed PostScript and ascii files for a paper on practice and experience operating NTP in the global Internet Mills, D.L.

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. Mills, D.L. The Fuzzball. Proc. ACM SIGCOMM 88 Symposium (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).
