Secure your computer network with SSH! With transparent, strong encryption, reliable public-key authentication, and a highly configurable client/server architecture, SSH (Secure Shell) is a popular, robust, TCP/IP-based solution to many network security and privacy concerns. It supports secure remote logins, secure file transfer between computers, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. Best of all, SSH is free, with feature-filled commercial versions available as well.

SSH: The Secure Shell: The Definitive Guide covers the Secure Shell in detail for both system administrators and end users. It demystifies the SSH man pages and includes thorough coverage of:

  • SSH1, SSH2, OpenSSH, and F-Secure SSH for Unix, plus Windows and Macintosh products: the basics, the internals, and complex applications.
  • Configuring SSH servers and clients, both system-wide and per user, with recommended settings to maximize security.
  • Advanced key management using agents, agent forwarding, and forced commands.
  • Forwarding (tunneling) of TCP and X11 applications in depth, even in the presence of firewalls and network address translation (NAT).
  • Undocumented behaviors of popular SSH implementations.
  • Installing and maintaining SSH systems.

Whether you're communicating on a small LAN or across the Internet, SSH can ship your data from "here" to "there" efficiently and securely. So throw away those insecure .rhosts and hosts.equiv files, move up to SSH, and make your network a safe place to live and work.

Secure Know-How!

By Mei

Comments about oreilly SSH, The Secure Shell: The Definitive Guide:

SSH: The Definitive Guide is an exemplary book written in detailed, easy-to-understand language that makes working with and understanding the SSH protocol and programs very simple.

Being an "ordinary user" myself, there were parts of this book that I did not understand very well, in every single case, these were chapters "meant for" sysadmins and other demi-gods and the authors made sure to mention this fact.

The book is also organized with this in mind, and so your approach to this book really depends on what level of expertise you already have with computer networking. I found that to be a valuable asset, as I am sure to return to this book when I learn more.

In addition to all of that, I found it to be a remarkably good starter for learning about and understanding cryptography. It is not a cyptography or cryptanalysis primer, but it does a surprisingly good job of explaining what these are to the uninitiated.

It's without doubt an extremeley helpful book that can come in handy and educational for both the average user and the system administrator.

This book is very good selling product for my customers. It is writed clear, with good level of technical details. Many technically detailed examples show how to configure a SSH servers with more variants of integrating SSH with non-Unix client platforms.

SSH, The Secure Shell: The Definitive Guide Review

By Charles Rowe

from Undisclosed

Comments about oreilly SSH, The Secure Shell: The Definitive Guide:

SSH, the Secure Shell: The Defintive Guide is another great book from O'Reilly. As the name would suggest, however, it's not so much a meant as a tutorial or a howto as it is an in-depth analysis of SSH's workings, though the examples given could probably be used as the former.

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.

SSH, The Secure Shell: The Definitive Guide Review

By Anonymous

Comments about oreilly SSH, The Secure Shell: The Definitive Guide:

An excellent guide for administrators or power users. Gives enough information to understand how to implement or accomplish tasks without going too deep into the inner workings. (Example: The cypher overview was brief and clear without delving into technical differences.) Discussions of different authentication methods are also handled well, and you'll definitely understand the trade-offs between hostbased, public key and passwd authentication well enough to make informed decisions.

Only drawback I could find was related to the extensive documentation on how the various software implementations differed and how un-documented or mis-documented features actually work. This information is really invaluable, but much will soon be outdated.

Comments about oreilly SSH, The Secure Shell: The Definitive Guide:

Before reviewing this book, I had used SSH but possessed no special understanding of the protocol or software. This book reads like a dream. Chapter 2, on basic SSH use is fantastic: the writing clear, the examples sound, and the benefit to SSH understanding great. It does a splendid job of laying a proper foundation which the rest of the text builds on. The chapters on the SecureCRT and F-Secure Windows clients are also excellent.

Comments about oreilly SSH, The Secure Shell: The Definitive Guide:

Blimey, this book is great. Although I am an experienced SSH user, its amazing to see the volume of subject matter covered. The authors have done a really good job at capturing all the essential elements - and much more. They should get a lot of well-deserved praise for providing us with this much needed text.

By Sergey Okhapkin

from Undisclosed

Comments about oreilly SSH, The Secure Shell: The Definitive Guide:

I like this book. It covers a wide range of tasks to solve with SSH, using a variety of protocol implementations and platforms. Topics range from "what is security" and "how to run SSH" up through advanced configuration and usage. This book will be very useful to both SSH administrators and users. I was a technical reviewer for this book. (I am also the developer of free Windows ports of SSH1 and SSH2.)
