Makes sense of the obscure land of SSH
This is compounded by the fact that the documentation for SSH just blows. For something that should be simple SSH is anything but a walk in the park. This book, however, does everything but blow. In classic O'Reilly fashion the author decomposes the topic and covers it effectively from almost every angle with excellent writing and superb graphics. This is a great book for anyone who uses SSH, or who is having issues with it.

why you should use ssh

In an earlier, more trusting Internet, rlogin, ftp and telnet were widely used for remote access. [A review of the 2nd EDITION 2005. 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.

SSHweet
This book is
exacly what the title says, it's a definitive guide to SSH. I recently finished reading SSH, The Secure Shell, The Definitive
Guide, by Barrett and Silverman over at O'Reilly. It covers
installation and use. It incorporates SSH usage in a semi how-to
fashion but it also contains what How-tos would leave out. It
describes the how and the why related to protocols, procedures,
programs (scp, sftp. . . ) and configurations. Through out the book they
discuss SSH1, SSH2 and OpenSSH (less) and a comparison of what one
SSH version has over the other. It covers aspects like Installation
and configuration, X11 Forwarding, Securing IMAP Auth and many others.

This book covers both the server and client aspect of SSH and I
would recommend this book to anyone who would like an in depth
look at SSH.
