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.

Administrator Skills Assumptions
If you aren't already fairly well-skilled in Linux/Unix/Windows, Apache, and so on, consider using TWiki:Codev.TWikiVMDebianStable
- this can be installed on Windows or Linux, and makes it possible to get a working TWiki system within 5 minutes (after a fairly big download), ready to use from your browser. This is ideal for personal use or evaluations - if you decide to go for production use then these AdminSkillsAssumptions apply to some degree, but you are starting from a working system.
If you need to install TWiki you'll need to either have or learn the following skills (even with TWikiVMDebianStable, you'll need these for upgrades). For each of these, the requirement is either pre-existing knowledge/skill, or the willingness to spend significant time (i.e. from hours to days) learning them:
- Operating system administration: Ability to use Unix/Linux command line tools (or equivalent Windows tools), including ability to move/copy/delete files, change permissions, view web server log files, set environment variables, use a text editor, etc.
- Web server administration: Ability to do basic setup, e.g. ability to edit config files or use GUI configuration tools to enable CGI scripts on a directory.
- Program compilation: Where Revision Control System (RCS) is not pre-installed (that is most Unix systems), the ability to download and compile the RCS program from source, including use of
make, etc. This is often not necessary on Linux or Windows.
- Troubleshooting: Ability to perform tests, inspect error logs, talk to technical support (whether in an IT department or web hosting provider) and read documentation in order to help with diagnosing installation problems.
Installing TWiki is not
recommended for people who only know HTML and web design, unless they are willing to learn the above, or team up with someone who can handle the installation.
Although the TWikiInstallationGuide
is quite complete, there will on occasion be parts that don't work in your local environment (particularly with TWiki:Codev/TWikiOnWebHostingSites
, which are sometimes challenging even for those with good OS and web server skills).
There are many excellent resources for learning how to administer your OS and web server, including books, web sites, web forums, IM and e-mail lists. The TWiki:Support
web must not
be depended on as a resource for this purpose - in other words, it is not there to answer basic questions about operating system and web server administration. Asking and answering questions is time consuming for all concerned and is best used for specific TWiki related
issues, rather than helping you learn the OS and web server.
To get started with Linux, visit LinuxBasics.org
. LinuxBasics.org offers Linux tutorials, a mailing-list and an IRC-channel to answer questions, and links to sites with information to install and use Linux. LinuxBasics.org now also offers a downloadable Linux 'virtual machine' (LBox) that runs on Windows - you can use this as a completely safe learning environment, and feel free to make mistakes without any chance of damaging your Windows setup.
A nice tool for people migrating from Windows is https://www.MidnightCommander.org/
. It is already installed on Linux systems: try
to get help.
