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.

TWiki Username vs. Login Username

This section applies only if your TWiki is installed on a server that is both authenticated and on an intranet.

TWiki internally manages two usernames: Login username and TWiki username.

• Login username: When you login to the intranet, you use your existing login username, for example pthoeny. This name is normally passed to TWiki by the REMOTE_USER environment variable. TWiki uses this name internally to log topic changes. Login usernames are maintained by your system administrator.
• TWiki username: This is your name in WikiNotation, for example PeterThoeny, recorded when you register in TWikiRegistration; doing so also generates your personal home page in the Users web of your TWiki site.

NTP can map the intranet username to the Wiki username automatically, provided that the Login username and Wiki username pair has been entered in the TWikiUsers topic. This happens automatically when you register.

NOTE: To correctly enter a WikiName - your own or someone else's - be sure to specify the Users web in front of the Wiki username: write Users.WikiUsername or %MAINWEB%.WikiUsername. This assures that the name will be linked automatically to the Users web, where user home pages are stored, even if the text is entered in a different web.
