NTP users are strongly urged to take immediate action to ensure that their NTP daemons are not susceptible to being used in distributed denial-of-service (DDoS) attacks. Please also take this opportunity to defeat denial-of-service attacks by implementing Ingress and Egress filtering through BCP38.

ntp-4.2.8p13 was released on 07 March 2019. It addresses 1 medium-severity security issue in ntpd, and provides 17 non-security bugfixes and 1 other improvements over 4.2.8p12.

Please see the NTP Security Notice for vulnerability and mitigation details.

Ntp Autogen Usage {GSOC2010}

Overview

This page gives in depth instruction on how to write manual page using autogen. Using autogen to write manual pages allows to save time by reducing the repetitive tasks that usually does in writing manual page in man macro pagkage , mdoc macro package or texi macro package. Also you may be a programmer having knowledge about only one macro package. For example you may be familiar with man macro package or you may be familiar with mdoc macro package.Interesting thing with autogen is that it allows you to creat man manual pages in mdoc macros. it allows you to creat mdoc manula pages in mdoc macro package. This page is aimed at giving you good understanding on how to use this capability that autogen provide.

How to set your machine up for testing NTP commands.

How to set up your machine for using extened autegen for automated manual page generation is discussed here considering ntp.keys(5) command.I selected this command because, i am writting this document while doing my developments on ntp commands. But instructions on this page is applicable any other documentation automation task using autogen.

Given Table Depicit the commands which are automated through extended autogen.

mdoc tags

Here is brief description of mdoc macro package.

mdoc package macros are categorized in to three types.

Page layout macros

- mdoc, page layout macros make up the page structure domain which consists of macros for titles, section headers,displays and lists - essentially items which affect the physical position of text on a formatted page.

General text domain macros

- The general text domain is defined as macros which perform tasks such as quoting or emphasizing pieces of text

Manual Domain Macros

- The manual domain is defined as macros that are a subset of the day to day informal language used to describe commands, routines and related UNIX files. Macros in the manual domain handle command names, command line arguments and options, function names, function parameters, pathnames, variables, cross references to other manual pages, and so on.

if you are using autogen to write manual page in mdoc macro package then it is not necessary to know about all the macros that mdoc macro package consist. This page gives you what are macros that you need to know and how you use them in autogen.

texi tags

Texinfo is a documentation system that uses a single source file to produce both online information and printed output. This means that instead of writing two different documents, one for the online information and the other for a printed work, you need write only one document. Therefore, when the work is revised, you need revise only that one document. Using autogen to create texinfo document allows you to save time by reducing the repetitive tasks that you do in writing texinfo file.

General Notes

Harlan was talking to stickster on #fedora-docs at freenode (http://fedoraproject.org/wiki/PaulWFrields) who recommended docbook, and said that installing the tools on Fedora is Really Easy.

Other items we care about include:

• GNUAutoGenConversion
• Searchable man pages (different released versions) - see PspPlans
