The main problem with this book is not that it is incomplete, but that you will probably have to wade through portions that do not apply to you to get to what you need to know.



The authors are knowledgable, and I had no problem with the presentation. However, I was looking for the format of ssh and scp commands for the purpose of programmng them in PERL and the needed security files that have to be present for those commands to work without the necessity of logging in every time. I found what I needed to know in this book, but I might have been better off if I had just done a web search for this information.



Likewise, network and UNIX administrators probably have the information they need in this book too, but they will have to wade through the information for programmers as well as the information for IT managers who are deciding whether or not to install SSH on their machines and why. I'd still recommend it since it is a well-written and well-illustrated book. Just be prepared to go digging for what applies to your specific situation.
