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.
Please contact postmaster@ntp.org if you have any questions about anything related to the mail system for ntp.org or the mailing lists we host at our site.

If you are unable to contact postmaster@ntp.org from your current address or system, please feel free to contact us from another address on another system, and we'll do everything we can to help you out.

We are also working on providing additional contact mechanisms that can be used by people who are not able to get e-mail to us at all. We will update this space when we have more information on these alternative contact mechanisms.

The Postmaster Services Team is well acquainted with the industry standard reference Internet Postmaster: Duties and Responsibilities booklet from the SAGE Short Topics series, and strives to equal or exceed the best practices recommended by the authors. However, we always welcome constructive criticism regarding areas in which we can improve.
