This section tries to answer questions about the document itself. This document is intended for beginners as well as advanced users that are looking for advice. However, basic skills in system administration are required to enjoy this tour. True experts on the subject will probably prefer the original documentation that comes with the software, or make corrections where it is wrong.
At that point focus moves from a more theoretical treatment of the subject to practical aspects, starting with Section 5. Then Section 6 moves into configuration of the NTP software. Section 7 will talk about reference clocks.
This document tries to answer frequently asked questions (FAQs) that can not (at least virtually) be answered easily from the standard documentation.
In addition to just answering user questions, this document also tries to give a gentle introduction and guidelines to the newcomer. The authors believe that it’s better to use NTP correctly right from the start rather than fixing all the problems after they occur.
“Gentle” means “not too technical” and “not too theoretical”. However, some basic non-trivial understanding of real life is required at several points, so please accept these deviations from the goal.
The answer to this question is quite delicate! The guidelines are probably these:
In “the good old times” the Internet was a valuable source of information, and people were happy to share their knowledge. These days, however, people think of E-Commerce, how to make money.
This FAQ was written not to make money, but to have a reference to refer to and to provide information to more people. If you have solved some NTP problem that may be of interest to other people, please share your experience.
Contributions are very much appreciated. You can:
Probably the fault of the editor. Maybe he thought you don’t want to be listed, or simply forgot. Section 1.10 shows the names the editor was aware of.
The popular GIF format supported by many browsers relies on a compression algorithm that is patented, and the owner of the patent wants to receive money from everyone making GIF files. PNG (Portable Network Graphics) uses a different algorithm for compression and does not require payment.
If you contributed to this FAQ, and you could not find your name elsewhere, this is where it should be.
