Secure your computer network with SSH! With end-to-end 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: * Basic to advanced use of SSH client tools for Unix, Windows, and Macintosh. * Installing, configuring, and maintaining SSH (with special tips for large data centers). * The three levels of SSH server control: compile-time and server-wide configuration for administators, and per-account configuration for end users. * Application tunneling, port and agent forwarding, and forced commands. * Undocumented features of popular SSH implementations. * Detailed case studies of creating complex applications with SSH. * Troubleshooting a wide variety of common and not-so-common problems.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.
