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.

Meta Data Rendering

Various meta data can be stored in topics - MetaDataDefinition

This is rendered using the %META% variable. This is mostly used in the view, preview and edit scripts.

At present support is fairly basic:

Variable usage: Comment:
%META{"form"}% Show form data, see Form Templates
%META{"attachments"}% Show attachments, excluding hidden ones. Options:
all="on": Show all attachments i.e. including hidden ones
%META{"moved"}% Details of any topic moves
%META{"parent"}% Show topic parent. Options:
dontrecurse="on": By default recurses up tree, this has some cost.
nowebhome="on": Suppress WebHome.
prefix="...": Prefix that goes before parents, but only if there are parents, default "".
suffix="...": Suffix, only appears if there are parents, default "".
separator="...": Separator between parents, default is " > ".

Possible future additions:

  • Rendering of form data to alternate formats e.g. bullet lists
  • Specify a template to be used for rendering
