Are you serious about network security? Then check out SSH, the Secure Shell, which provides key-based authentication and transparent encryption for your network connections. It's reliable, robust, and reasonably easy to use, and both free and commercial implementations are widely available for most operating systems. While it doesn't solve every privacy and security problem, SSH eliminates several of them very effectively.Everything you want to know about SSH is in our second edition of SSH, The Secure Shell: The Definitive Guide . This updated book thoroughly covers the latest SSH-2 protocol for system administrators and end users interested in using this increasingly popular TCP/IP-based solution.How does it work? Whenever data is sent to the network, SSH automatically encrypts it. When data reaches its intended recipient, SSH decrypts it. The result is "transparent" encryption-users can work normally, unaware that their communications are already encrypted. SSH supports secure file transfer between computers, secure remote logins, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. With SSH, users can freely navigate the Internet, and system administrators can secure their networks or perform remote administration.Written for a wide, technical audience, SSH, The Secure Shell: The Definitive Guide covers several implementations of SSH for different operating systems and computing environments. Whether you're an individual running Linux machines at home, a corporate network administrator with thousands of users, or a PC/Mac owner who just wants a secure way to telnet or transfer files between machines, our indispensable guide has you covered. It starts with simple installation and use of SSH, and works its way to in-depth case studies on large, sensitive computer networks.No matter where or how you're shipping information, SSH, The Secure Shell: The Definitive Guide will show you how to do it securely.

Great! Keep up with the good work! ; - )
[A review of the 2nd EDITION 2005.] In an earlier, more trusting Internet, rlogin, ftp and telnet were widely used for remote access. But the increase in malware sniffing of these plaintext channels has led to ssh largely supplanting them. The book explains why you as a user should prefer ssh. It greatly helps to guard your account and its password. No small matter if this account has sensitive data. Actually, if you are also a sysadmin, you may want to consider restricting secure remote access to ssh. The book deals with the broad outline of the cryptographic underpinnings. But it does not require you to understand any of the formal maths. (Whew!) As a practical matter, the bulk of the text is taken up with the myriad ways that ssh implementations can be used. Shows the crucial role played by ssh. Possibly the hardest part concerns key management. Which is often the bane of any cryptosystem. So you should not regard this as a particular failing of ssh.
SSH, the Secure Shell: The Defintiive 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.
As a System Administrator and consultant, it is difficult to find a text that covers a subject well enough to encourage others to read. This text is the most comprehensive guide to the details of the use of all variations of SSH programs in the market. My particular program of interest is OpenSSH, and this guide does a marvelous job of detailing all aspects of the application. In addition, the authors spent a considerable amount of time and energy to give the reader a clear understanding of the differences between each application. As usual, Oreilly books can get very technical, and this book is designed for people that have had the opportunity to play with SSH...even for only a brief period of time. The web is a better place if you have never used SSH before...but if you ever plan on using SSH for anything worthwhile, you better have this book on the shelf!
