Reading This Book

This book is divided roughly into three parts. The first three chapters are a general introduction to SSH, first at a high level for all readers (Chapters 1 and 2), and then in detail for technical readers (Chapter 3).

The next nine chapters cover SSH for Unix and similar operating systems (OpenBSD, Linux, Solaris, etc.). The first two (Chapters 4 and 5) cover SSH installation and serverwide configuration for system administrators. The next four (Chapters 6,7,8,9) cover advanced topics for end users, including key management, client configuration, per-account server configuration, and forwarding. We complete the Unix sequence with our recommended setup (Chapter 10), some detailed case studies (Chapter 11), and troubleshooting tips (Chapter 12). The remaining chapters cover SSH products for Windows and the Macintosh, plus brief overviews of implementations for other platforms.

Each section in the book is numbered, and we provide cross-references throughout the text. If further details are found in Section 7.1.2.2, we use the notation [7.1.2.2] to indicate it.
