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.

• Back up your system.
• Update the templates in the /templates directory (and its subdirs):
  • Take the templates of the latest distribution as the base and merge your changes back into it.
• Update the Perl scripts in the /bin directory:
  • Take the scripts of the latest distribution as the base and merge your changes back into it. Do so also for wikicfg.pm because it has important changes as well.
• Update topics:
  • Copy the new Main. TWikiPreferences topic (and *,v file) into your TWiki.Main web. Customize the topic to your needs.
  • Copy the new Main. WebPreferences, WebStatistics topics (and *,v files) into all your webs. Customize all WebPreferences topics to your needs (e.g. web color).
  • Copy WebSearch into all your webs, or modify the existing ones. Reason: Some switches for search changed.
  • Copy the TWiki documentation into your Main web: Topics TWikiDocumentation, TWikiUsernameVsLoginUsername, TWikiVariables, WebNotification , TWikiCategoryTable, TWikiImplementationNotes , TWikiInstallationGuide, TWikiUpgradeTo01May2000, TextFormattingRules, TWikiHistory .
  • Copy the registration topic into your Main web:
    • In case you are on an Intranet: Copy topic TWikiRegistration to Main.TWikiRegistration. Customize if needed.
    • In case you are on a public server: Copy topic TWikiRegistrationPub to Main.TWikiRegistration. Customize if needed.
  • Copy the Main. TWikiWebsTable topic (and *,v file) into your Main web and customize it. Reason: The new release does not use the *.inc include files anymore.
  • Optionally: Search for %INCLUDE%'s in all your webs and change them to the new %INCLUDE{"file.ext"}% syntax. Note: Your old %INCLUDE:"file.ext"% syntax still works (the legacy rule is defined in wikicfg.pm .)
• Add the PoweredByTWikiLogo to your NTP home page.
