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.

Multicast Status and Issues

Fixing the last Multicast bugs

To our knowledge in the current ntp-dev:

  • IPv4 broadcast and multicast work on all known Unix systems
  • IPv4 broadcast works on Windows systems
  • IPv6 multicast client is known to work on Solaris
  • IPv6 multicast client is known to work on FreeBSD
  • IPv6 multicast server is known to work on FreeBSD
  • IPv4 multicast works on Windows systems with authentication disabled
  • IPv4 multicast fails on Windows systems with authentication enabled

Making sure IPv6 is working

DannyMayer believes IPv6 is working everywhere where IPv6 is supported except under Windows (using ntp-dev).

If you disagree, please let us know.
