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. For anonymous FTP retrieval, the base directory pub/ntp contains the distributions and related stuff, including: README This file doc/ various bits of documentation hardware/ Various harware-specific things ntp3/ The (old) NTP3 distribution ntp4/ The NTP4 distribution sim/ Various simulation packages software/ Various software bits. The doc subdirectory includes a number of compressed files containing papers, rfcs and technical reports on NTP and related topics. 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. Note: PostScript and ASCII files for miscellaneous reports on computer network time synchronization have been relocated to World Wide Web home pages http://www.eecis.udel.edu/~ntp NTP home page http://www.eecis.udel.edu/~mills David L. Mills home page http://www.eecis.udel.edu/~millslab UDel Internetworking Lab home page dts1.txt.Z, dts2.txt.Z Compressed ASCII files containing unpublished message digests comparing NTP and the Digital Time Synchronization Service (DTSS).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 excerpted, even with attribution. dts3.ps.Z, dts3.txt.Z Compressed PostScript and ASCII files for an unpublished technical memorandum comparing NTP and the Digital Time Synchronization Service (DTSS).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 should not be cited or excerpted without the consent of the author. faq.Z Compressed ASCII file containing frequently asked questions about NTP, its installation, configuration and management. Refreshed at irregular intervals. info1.txt.Z, info2.txt.Z Compressed ASCII files containing useful hints and kinks on setting up NTP service jaguar.txt.Z Compressed ASCII file containing a job description for a Maya high priest taken from the Book of Chillum Balum. Useful for after-dinner speakers and rally cheerleaders. security.ps.Z Compressed PostScript file containing a draft of a report by Matt Bishop discussing security issues in NTP. It should not be cited or excerpted without the permission of the author. The depredated directory contains previous versions of the NTP protocol implementations. There use is strongly discouraged in new installations. There is no guarantee that these versions will be supported in future. 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. xntp2 Subdirectory containing the NTP Version 2 daemon for Unix written by Dennis Fergusson of the University of Toronto. Not recoommended for new installations. xntp3.3wx.tar.Z Compressed tar archive containing a prior version of xntp3 intended for program development purposes only. This version works for most machines, except the Cray. xntp3.3wy.tar.Z Compressed tar archive containing a prior version of xntp3 intended for program development purposes only.
