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.

The NatSkin

NatSkin is a skin driven by cascading stylesheets. This is a rework of the TWiki:Plugins/CopyCatSkin by TWiki:Main/MattWilkie. It is used at the Natural Language Systems Division (NATS) of the University of Hamburg, Germany. The NatSkin comes with 19 predefined styles that are inspired by the MovableType and WordPress among others a port of the Kubrick style by Michael Heilemann.

The NatSkin includes an enhanced navigation mechanism named WebSideBar. This combines the best of the old WebMenu idea from the GnuSkin and the WebLeftBar known from the TWiki:Plugins/PatternSkin by providing all the flexibility of the WebLeftBar including the MySideBar feature and an enhanced navigation scheme. See the NatSkinPlugin documentation for more information.

Selecting Styles

You can try alternative styles

1. per request: by appending style=<skin-name> to the end of the url; if you use the SessionPlugin this will be sticky; alternatively, use the style browser below. (tip: you might want to add %SKINSTYLEBROWSER% to your sidebar)
2. per topic: add a =%SETSKINSTYLE{"<name>"}% to the topic text
3. per user by setting a variable SKINSYLE on your TWikiGuest homepage
4. per web by setting the variable SKINSTYLE in the WebPreferences
5. site-wide by setting the skinstyle in the TWikiPreferences

The default style is hardcoded into the NatSkinPlugin (Clean).

%SKINSTYLEBROWSER%

Installation

• Get the TWiki:Plugins.NatSkinPlugin supplementary package and install it.
• Get the TWiki:Plugins.RedDotPlugin for red dots on the WebSideBar (or delete the =%REDDOT{...}% macros from the WebSideBar topic).
• If you are installing on TWiki/Cairo then consider applying the patches
  • Cairo_UI_pm.diff: fixes a bug in UI.pm
  • TablePlugin_pm.diff: adds full CSS support to the TablePlugin supported by the NatSkin of course; this patch is against the current version uploaded to TWiki.org and not suitable otherwise, i.e. not needed if you run a TWiki/dakar engine.
• Download the ZIP file from the Skin Home page (see below)
• Unzip NatSkin.zip in your twiki installation directory
