Negative Positive
Title: Disappointingly light
Review: I wanted a book that explains how NTP works, so I gambled $4.00 on a used copy of this one.I lost.If you want some lightweight handholding in setting up an NTP configuration, especially on Unix/Linux systems, this book would be OK. It's no substitute for the reference documentation that comes with NTP software, but it does give a reasonable overview--the sort of thing that could be easily conveyed in a ten-page white paper, not a whole book.However, if you want a robust explanation of what NTP does to handle errors, clock drift, and communication problems, this isn't it. There are a few packet dumps, but the explanation doesn't say much about what the packets mean, and doesn't begin to touch on how the protocol actually works.I fund no outright errors in the book, just an extraordinary percentage of fluff. I should have boughtComputer Network Time Synchronization: The Network Time Protocolin the first place.
Is the review positive or negative?
