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-4.2.8p15 was released on 23 June 2020. It addresses 1 medium-severity security issue in ntpd, and provides 13 non-security bugfixes over 4.2.8p13.

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

Are you using Autokey in production? If so, please contact Harlan - he's got some questions for you.


Footnotes are notes placed at the end of a topic.

Syntax Rules

Write {{ note text }} anywhere in a TWiki topic. This will be replaced with a link to the note at the end of the topic. The footnote has a link back to the text where it was inserted.

Write {{f: note text }} to use label format f instead of the default numerical footnote labeling. Available formats are:

  • 1 : Arabic numerals
  • A , a : Upper- or Lower-case letters
  • I , i : Upper- or Lower-case roman numerals
  • X , x : Upper- or Lower-case hexadecimal numbers.

Write {{l:: note text }} to use the label l instead of automatic numbering. Valid labels may be any length and contain alphanumeric characters, but must not include spaces.

%FOOTNOTELIST% will be replaced by the notes so far on the page.

%FOOTNOTE{LIST="Web.Topic"}% will be replaced by the notes from an %INCLUDE% ed page.

%STARTFOOTNOTE{LABEL="l" LABELFORMAT="f"}% note text %ENDFOOTNOTE% may also be used instead of {{ note text }}

Do not embed footnotes in headings. That will break the heading in the %TOC%.


  • You type:
    • Tim Berners-Lee{{Tim Berners-Lee is now director of the World Wide Web Consortium, and Professor of Computer Science at Southampton ECS.}} invented the World Wide Web.
  • If the plugin is installed you get:
