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-4.2.8p13 was released on 07 March 2019. It addresses 1 medium-severity security issue in ntpd, and provides 17 non-security bugfixes and 1 other improvements over 4.2.8p12.

Please see the NTP Security Notice for vulnerability and mitigation details.

Redirect Plugin

Create a redirect to another topic or website.

I typically use this to make easy-to-type shortforms/acronyms of topic names. For example:

• Actual content appears under Main.LightweightDirectoryAccessProtocol
• Main.LDAP contains just a redirect tag. Referencing Main.LDAP anywhere or entering it in the Go box takes one directly to Main.LightweightDirectoryAccessProtocol

Syntax Rules

• Redirect to a topic within the web: %REDIRECT{"SomeTopic"}%
• Redirect to a topic in another web: %REDIRECT{"Someweb.SomeTopic"}%
• Redirect to any URL: %REDIRECT{"http://domain.com/"}%
• Pass parameters:
  • Url parameters are passed on: http://domain.com/twiki/bin/view/Main/TopicThatContainsARedirect?q=LDAP"}%. The landing topic url will contain these parameters
  • Parameters can also be passed to the variable: %REDIRECT{"Someweb.SomeTopic?q=LDAP"}%
  • REDIRECT parameters override url parameters

Prevent redirecting

To view the topic that contains a REDIRECT, pass parameter noredirect=on to the url. For example:

http://domain.com/twiki/bin/view/Main/WebHome?noredirect=on

Wikipedia like "Redirected from..."

A redirect now appends the redirectedfrom parameter to the url which contains the Web.Topic that the user has been redirected from. This allows us to display Wikipedia like "Redirected from ..." text on the destination topic. You can use the %URLPARAM{redirectedfrom}% variable to access the parameter and create the "Redirected from..." text.

Below is an example you can put in your template:

%IF{ "$'URLPARAM{redirectedfrom}'" then="<span class='twikiGrayText'>(Redirected from <a href='%SCRIPTURLPATH{view}%/%URLPARAM{redirectedfrom}%?noredirect=on'>%URLPARAM{redirectedfrom}%</a>)</span>"}%

Which will display the following on topics that have been redirected:

(Redirected from Web.Topic)
