This directory and its subdirectories contain NTPSec, a security-hardened implementation of Network Time Protocol Version 4. You can browse a summary of differences from legacy NTP here:
The contents of the base directory are given in this file. The contents of subdirectories are usually given in the README files in each subdirectory.
The base directory ./ contains the configuration files, source directories and related stuff:
- INSTALL.adoc
-
Generic installation instructions.
- NEWS.adoc
-
What’s new in this release.
- README.adoc
-
This file.
- LICENSES/
-
License texts in REUSE format. See http://reuse.software
- VERSION
-
The version stamp, to be used by scripts and programs.
- attic/
-
Directory containing source code that is not part of a normal installation. Things can disappear from here at any time.
- buildprep
-
Executable script for fetching installation prerequisites.
- contrib/
-
Directory containing contributed scripts, dragons dwell here. Some of this might eventually move to being supported code.
- devel/
-
Documentation and small tools aimed at developers. Includes a hacking guide and a tour of the internals.
- docs/
-
Directory containing a complete set of documentation on building and configuring a NTP server or client. The files are in asciidoc markup. This replaces the 'html' directory of previous versions, but html can be generated from it.
- etc/
-
Directory containing a motley collection of configuration files and launch scripts for various systems. For example only.
- include/
-
Directory containing include header files used by most programs in the distribution.
- libjsmn/
-
A minimal JSON library used by the GPSD-JSON driver.
- libntp/
-
Directory containing library source code used by most programs in the distribution.
- libparse/
-
This directory contains the files making up the parser for the parse refclock driver. For reasonably sane clocks this refclock drivers allows a refclock implementation by just providing a conversion routine and the appropriate NTP parameters
- ntpclients/
-
Directory containing sources for clients - utility programs to query local and remote NTP installations for log status, state variables, and other timekeeping information. The term "clients" is used quite loosely here; any tool that is not a multi-file C program probably lives in this directory.
- ntpd/
-
Sources for the main time-synchronization daemon.
- ntpfrob/
-
The ntpfrob utility collects several small diagnostic functions for reading and tweaking the local clock hardware, including reading the clock tick rate, precision, and jitter.
- ntptime/
-
Directory containing a utility for reading and modifying kernel parameters related to the local clock.
- packaging/
-
Parts and guidance for distribution packagers.
- pylib/
-
Installable Python helper modules for scripts.
- tests/
-
Self-test code.
- waf
-
A copy of the waf builder. This is the engine used to configure and build the codebase.
- wafhelpers/
-
A library of Python procedures used by the waf build system.
- wscript
-
NTP-specific waf rules.
