The first chapters of the book begin with a lookat what SSH is, a summary of its general uses, and the differences between the various SSH implmentations. It then quickly moves onto a number of practical examples, with explanations of both the 'how' and 'why' behind the examples.

Some of the more interesting examples are those that demonstrate X11 tunnelling, key management, and how SSH can be integrated with other applications (such as PGP, for example).

One of the major faults of the book is in the writing style. The regular switching back and forth between a conversational tone and a serious, technical one was something that I found rather annoying. But other than that, this is more or less a well-rounded and nicely written book on SSH, and I would certainly recommend it to anyone who is interested in this topic.
