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.

TWiki Skins

Skins overlay regular templates with alternate header/footer layouts. You can use Skins to change the look of a TWiki topic, for example, the layout of the header and footer. Rendered text between header and footer does not change. You can also use Skins to define an alternate view, like a view optimized for printing.

To see the installed TWikiSkins, see TWikiSkinBrowser.
