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.

Help Wanted

Mailing List Moderators wanted

We one (or more) volunteers who are willing to donate ~5 to ~20 minutes a day (total) to moderate our 41 (!) mailing lists. The daily time commitment for this task depends on the amount of traffic on the lists. Most of the time this task will take 10 minutes/day or less.

NMEA messages over TCP

I would like help creating a clock driver that will allow me to send NMEA messages over TCP instead of using a serial input.

I am close to having this working but the serial interface is very ingrained into the ntp code architecture that it is making it difficult to receieve data from anything but a serial interface.

I would be glad to write this interface but need a little help in creating it without a serial port.

I think you'll want to use UDP instead of TCP. You'll want to get the PPS timestamp on the remote machine, too, and probably communicate the results to the machine that runs NTP any way you like, and then use the shared-memory refclock driver to get the data into NTP.
