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.

BitKeeper Notes

For more information about using or tracking NTP repositories using either the opensource or commercial BitKeeper programs see SoftwareDevelopment.

The purpose of these pages is to present a gentle introduction to bitkeeper commands. Some of the subpages will contain questions about what might belong there so, by all means, add what you think is appropriate.

BitMover's Users Guide for bk can be found at http://www.bitkeeper.com/UG/map.html .

Running bk help release-notes will show you the release notes for your version of bk.

There is a way to browse a repository managed by BitKeeper, general public can visit http://bk.ntp.org/ and there select the ntp-dev or ntp-stable repository. This is a very helpful and quick BK installation-less way to easily browse through all revisions in the repositories.

BitKeeper overview and terminology

These pages introduce the basic usage of BitKeeper and some of the more common terminology you'll run across.

• BkDirectoryContents
• BkCheckOutEdit
• BkListFile
• BkPrs
• BkRevtool
