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-4.2.8p6 was released on 19 January 2016. It addresses 9 low- and medium-severity security issues, 10 bugfixes, and contains other improvements over 4.2.8p5.

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.

7. Starting NTP

7.2. How is NTP started?

On Unix-like operating systems NTP is started by an init script. If you are installing a pre-packaged version of NTP, the init script infrastructure may be pre-configured for you. If you are installing directly from the source you may have to manually configure your init system to start NTP at boot time.

7.3. When should NTP be started?

NTP should be started early in the boot process: after the network and DNS (if you are using any names instead of IP addresses for your servers/peers) are configured, but before any time-sensitive services are started.
