1 = The NTPsec distribution base directory =
3 This directory and its subdirectories contain NTPSec, a
4 security-hardened implementation of Network Time Protocol Version 4.
5 You can browse a summary of differences from legacy NTP here:
7 https://docs.ntpsec.org/latest/ntpsec.html
9 The contents of the base directory are given in this file. The contents of
10 subdirectories are usually given in the README files in each subdirectory.
12 The base directory ./ contains the configuration files, source
13 directories and related stuff:
15 INSTALL.adoc:: Generic installation instructions.
17 NEWS.adoc:: What's new in this release.
19 README.adoc:: This file.
21 LICENSES/:: License texts in REUSE format. See http://reuse.software
23 VERSION:: The version stamp, to be used by scripts and programs.
25 attic/:: Directory containing source code that is *not* part of a
26 normal installation. Things can disappear from here at any
29 buildprep:: Executable script for fetching installation prerequisites.
31 contrib/:: Directory containing contributed scripts, dragons dwell here.
32 Some of this might eventually move to being supported code.
34 devel/:: Documentation and small tools aimed at developers.
35 Includes a hacking guide and a tour of the internals.
37 docs/:: Directory containing a complete set of documentation on
38 building and configuring a NTP server or client. The files
39 are in asciidoc markup. This replaces the 'html' directory
40 of previous versions, but html can be generated from it.
42 etc/:: Directory containing a motley collection of configuration files
43 and launch scripts for various systems. For example
46 include/:: Directory containing include header files used by most
47 programs in the distribution.
49 libjsmn/:: A minimal JSON library used by the GPSD-JSON driver.
51 libntp/:: Directory containing library source code used by most
52 programs in the distribution.
54 libparse/:: This directory contains the files making up the parser for
55 the parse refclock driver. For reasonably sane clocks
56 this refclock drivers allows a refclock implementation
57 by just providing a conversion routine and the
58 appropriate NTP parameters
60 ntpclients/:: Directory containing sources for clients - utility programs
61 to query local and remote NTP installations for log status,
62 state variables, and other timekeeping information. The term
63 "clients" is used quite loosely here; any tool that is not a
64 multi-file C program probably lives in this directory.
66 ntpd/:: Sources for the main time-synchronization daemon.
68 ntpfrob/:: The ntpfrob utility collects several small diagnostic
69 functions for reading and tweaking the local clock
70 hardware, including reading the clock tick rate,
71 precision, and jitter.
73 ntptime/:: Directory containing a utility for reading and modifying
74 kernel parameters related to the local clock.
76 packaging/:: Parts and guidance for distribution packagers.
78 pylib/:: Installable Python helper modules for scripts.
80 tests/:: Self-test code.
82 waf:: A copy of the waf builder. This is the engine used to configure
83 and build the codebase.
85 wafhelpers/:: A library of Python procedures used by the waf build system.
87 wscript:: NTP-specific waf rules.
89 www/:: Sample ntpviz files
