SSH, The Secure Shell: The Definitive Guide

Rate this book
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.

Even though this book was fun to read and contains some interesting ssh trivia. It is starting to show its age in a quite severe way. But if you read around the outdated things, there are quite some good bits in there which are explained quite well.

One of my favorite security books. Addresses the holes.
A bit out dated, but it is a good foundation to start digesting the complex topics
