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-4.2.8p11 was released on 27 February 2018. It addresses 2 low-/medium-, 1 informational-/medium-, and 2 low-severity security issues in ntpd, 1 medium-severity security issue in ntpq, and provides over 65 non-security bugfixes and other improvements over 4.2.8p10.

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

NTP.Users Web Preferences

The following settings are web preferences of the NTP.Users web. These preferences overwrite the site-level preferences in TWikiPreferences, and can be overwritten by user preferences (your personal topic, i.e. TWikiGuest in the NTP.Users web)

Preferences:

  • Web specific background color: (Pick a lighter one of the StandardColors)
    • Set WEBBGCOLOR = #FFFFC0

  • List this web in the SiteMap:
    • If yes, Set SITEMAPLIST = on, 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. Users.Topic links.
    • Set SITEMAPLIST = on
    • Set SITEMAPWHAT = Welcome to NTP... Users, Groups - tour this expandable virtual workspace.
    • Set SITEMAPUSETO = ...get a first-hand feel for TWiki possibilities.

  • Exclude web from a web="all" search: (Set to on for hidden webs)
    • Set NOSEARCHALL =

  • Users or groups who are not / are allowed to view / change / rename topics in the Users web: (See TWikiAccessControl)
    • Set DENYWEBVIEW =
    • Set ALLOWWEBVIEW =
    • Set DENYWEBCHANGE = TWikiGuest
    • Set ALLOWWEBCHANGE =
    • Set DENYWEBRENAME = TWikiGuest
    • Set ALLOWWEBRENAME =

  • Web preferences that are not allowed to be overridden by user preferences:
    • Set FINALPREFERENCES = WEBTOPICLIST, DENYWEBVIEW, ALLOWWEBVIEW, DENYWEBCHANGE, ALLOWWEBCHANGE, DENYWEBRENAME, ALLOWWEBRENAME

Notes:

  • A preference is defined as:
    6 spaces * Set NAME = value
    Example:
    • Set WEBBGCOLOR = #FFFFC0
  • Preferences are used as TWikiVariables by enclosing the name in percent signs. Example:
    • When you write variable %WEBBGCOLOR% , it gets expanded to #FFFFC0 .
  • The sequential order of the preference settings is significant. Define preferences that use other preferences first, i.e. set WEBCOPYRIGHT before WIKIWEBMASTER since %WEBCOPYRIGHT% uses the %WIKIWEBMASTER% variable.
  • 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).
