The suite of utility applications that Unix users and administrators find indispensable--Telnet, rlogin, FTP, and the rest--can in fact prove to be the undoing of interconnected systems. The Secure Shell, a.k.a. SSH (which isn't a true shell at all) provides your otherwise attack-prone utilities with the protection they need. SSH: The Secure Shell: The Definitive Guide
explains how to use SSH at all levels. In a blended sequence, the book explains what SSH is all about, how it fits into a larger security scheme, and how to employ it as an everyday user with an SSH client. More technically detailed chapters show how to configure a SSH server--several variants are covered--and how to integrate SSH with non-Unix client platforms.
As befits its detail- and variation-rich subject, this book comprises many specialized sections, each dealing with some specific aspect of use or configuration (setting up access control at the account level, for example, or generating keys for a particular SSH server). The writing is both informative and fun to read; the authors switch back and forth between text and entry-and-response listings from SSH machines. They often run through a half-dozen or more variants on the same command in a few pages, providing the reader with lots of practical information. The discussion of how SSH fits into a Kerberos Public Key Infrastructure (PKI) is great, as is the advice on defeating particular kinds of attacks. --David Wall

"Still the best SSH book out there by a long shot, but too much on Tectia and not enough on OpenSSH 4." - Paul Hudson, Linux Format, October 2005 "The authors manage to convey what SSH is all about as a concept and how to use it in the real world with equal aplomb, and highly technical configuration details are explained with clarity. They are happy to related how to integrate SSH into non-Unix clients, which makes a pleasant change from the typical Unix gurus who write books such as this. Whenever with see the words "definitive guide' included in the title of a book, we usually prepare ourselves for something far from it. The exception being when O'Reilly are the publishers, and this SSH guide is certainly as definitive as any you are likely to read. And read it you should if you are seriously involved with network security." Davey Winder, PC Plus, November 2005
