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.

Documentation Notes

HTML Pages

Harlan runs the following script to check the HTML documentation:

#! /bin/sh

cd html-new

for i in `find * -type f | grep -v '^x/'`
do
        cmp -s ../html/$i $i || ( cp ../html/$i $i ; echo $i )
done

linklint /@ -doc x

and the actual reconciliation between DLM's published documentation and the versions in the NTP distribution are done in /whimsy/ntp-html/ .
