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.

NTP.IETF Web Preferences
The following settings are web preferences
of the NTP.IETF web. These preferences overwrite the site-level preferences
, and can be overwritten by user preferences
(your personal topic, i.e. TWikiGuest
in the NTP.Users web)
- List of topics of the NTP.IETF web:
- Web specific background color: (Pick a lighter one of the StandardColors)
- List this web in the SiteMap:
- If yes, set SITEMAPLIST to
on, do not set NOSEARCHALL, and add the "what" and "use to..." description for the site map. Make sure to list only links that include the name of the web, e.g. IETF.Topic links.
- Set SITEMAPLIST = on
- Set SITEMAPWHAT = IETF Working Group for NTP
- Set SITEMAPUSETO = ...collaborate on the NTPv4 specification
- Exclude web from a
web="all" search: (Set to
on for hidden webs)
- Default template for new topics and form(s) for this web:
- Users or groups who are not / are allowed to view / change / rename topics in the IETF web: (See TWikiAccessControl)
- Users or groups allowed to change or rename this WebPreferences topic: (I.e. TWikiAdminGroup)
- Web preferences that are not allowed to be overridden by user preferences:
- Set FINALPREFERENCES = WEBTOPICLIST, DENYWEBVIEW, ALLOWWEBVIEW, DENYWEBCHANGE, ALLOWWEBCHANGE, DENYWEBRENAME, ALLOWWEBRENAME
- A preference is defined as:
6 spaces * Set NAME = value
- Preferences are used as TWikiVariables by enclosing the name in percent signs. Example:
- When you write variable
%WEBBGCOLOR% , it gets expanded to
- The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set
%WEBCOPYRIGHT% uses the
- You can introduce new preferences variables and use them in your topics and templates. There is no need to change the NTP engine (Perl scripts).
