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-4.2.8p12 was released on 14 August 2018. It addresses 1 low-/medium-severity security issue in ntpd, 1 low-severity security issue in ntpq and ntpdc, and provides 27 non-security bugfixes and 4 other improvements over 4.2.8p11.

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

Creating a new List entry

You must be a registered TWiki member to create a List entry for your Time Server. You will be prompted to login when necessary.

Entering the server information

There are two places to enter information on the edit page:

The text area
The ServerForm

Use the ServerForm to enter the standard information about your Time Server. The ServerForm is located below the text area.

Use the text area for general notes that don't fit in the ServerForm. Please keep these notes short and create them as bullet items under the Notes: heading. Please keep long policy documents on your web-server and just create links to them.

Please see the TextFormattingRules for more information about the simple TWiki Text Formatting Rules. There is a handy link to Text Formatting Rules at the bottom of the text area on the topic edit page.

Protecting your List entry

The ALLOWTOPICCHANGE variable under the settings: heading of your List entry is used to prevent others from making unauthorized modifications to your Time Server information. The format is:

   * Set ALLOWTOPICCHANGE = %MAINWEB%.YourWikiName

The ALLOWTOPICCHANGE variable is automatically populated with your WikiName when you create a Time Server List entry.

The ALLOWTOPICCHANGE variable will accept a comma delimited list of WikiNames and/or TWikiGroups in the event that you need to grant multiple editors permission to maintain your Time Server information. Please contact webmaster@ntp.org if you wish to set up a TWikiGroup for your Time Server.

You should know the members of the TWikiAdminGroup will be able to edit your Time Server List entry regardless of the ALLOWTOPICCHANGE setting.

Saving your List Entry

When you're done you may either save or preview your server entry.

To save: click the [save] button at the top of the page (or use the Alt-s shortcut).

To preview: click the [preview] button at the top of the page (or use the Alt-p shortcut) to preview the page. If you want to change something use your browser back button to return to the edit page. Make sure to click the [save] button on the preview page to actually save your updated entry.

Editing an existing List entry

You must be a registered TWiki member to edit an existing List entry for your Time Server. You will be prompted to login when necessary.

Time Server List entries which were imported from the previous lists were locked to prevent unauthorized modification. Please contact webmaster@ntp.org to get your WikiName added to the Access Control List.

Finding the List entry

You may search for your List entry by entering a portion of your host name (e.g. the domain) as lower case text in the Go/Search box at the top of any page and clicking the Go/Search button. If there is only one match you will, after a few seconds, see that Time Server List entry. If there are multiple matches you will, after a few seconds, see a page listing the entries.
