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, and 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, for security.

This text introduces UNIX to computer science majors and nonmajors, covering basics, simple scriptwriting concepts, and writing shell programs. Material progresses from file systems, shells, filters, and communications, to Korn shell programming and C shell programming. No knowledge of UNIX is assumed, although the reader should be computer literate. Learning features include summaries, questions, exercises, and lab sessions. Many tables, scripts, and code examples are included. The authors are affiliated with De Anza College. Designed as one of the first true textbooks on how to use the UNIX operating system and suitable for a wide variety of UNIX based courses, UNIX and Shell Programming goes beyond providing a reference of commands to offering a guide to basic commands and shell programming. Learn about regular expressions, grep, sed, and awk. The book begins by introducing students to basic commands and tools for the UNIX operating system.
In this timely new book, the authors present an in depth study of the C shell as a command interpreter and the gateway to other programs and utilities running under UNIX. They discuss the C shell as it runs under UNIX 4.2 BSD and 4.3 BSD. In addition, they detail the differences found in versions running under UNIX System V, System III, XENIX, and Version 7. As a guide to this powerful interface, this book: shows you how to use the C shell effectively; explains its practical features; and offers guidelines to using the C shell based on the author's experience. Among its special features, the book: offers situations typical to the software developer; presents the C shell's basic command forms, power, command shorthand, history, and alias mechanisms; shows how to customize the C shell to accommodate terminal types, working habits, login and logout procedures, and custom commands; includes diagrams to show how the C shell and Unix execute commands.
This true beginning level guide shows readers how to maximize the popular UNIX C Shell -- both a command interpreter and a programming language. Using the effective format of this well-known series, this book helps readers work comfortably with the features and facilities of the C Shell, understand its capabilities for programming, and design and write C Shell scripts. With this comprehensive tutorial of step-by-step lessons, users learn how to utilize the UNIX C shell to optimize their system, increase productivity, and work more efficiently. Explains the C shell's capabilities for programming. Shows users how to design and write their own C shell scripts. Covers shell variables, customization of the user environment, file redirection, pipes, filters, and the C shell commands. Books exclusively on the C-shell are not as commonplace as you might expect.
Two important features -- a hands-on guide to installation and use of ssh. An analysis of the security issues that arise when you install a tool that provides remote file access to the system. With this book, the reader gets to see what happens to configuration and log files when running ssh. What the reader needs--This book shows the administrators what they ned to know to be able to login into their system from anywhere and manage the files. At the same time, it explains how to prevent a cracker from having access to the system due to an application that they installed to make their lives easier. A great beginner's reference for compiling, installing and configuring Secure Shell (SSH), as well as learning some of the additional tricks it can do. UNIX System Administrators with little or no knowledge of SSH will find this to be an excellent, step-by-step guide.
A UNIX Shell Object is a unique piece of code that is written with the UNIX Shell using modern object-oriented approaches that make the code more powerful and easier to use over a network or the Web. The techniques in this book are original, and programmers can thrive as they make their Shell scripts more useful and powerful. The CD-ROM contains code from the book, GNU CygWin32 tools, and the Java Developer's Kit. Topics include: The Nature of Object-Oriented Programming; The Shell as a User and Programming; The Syntax of Writing Classes; Using Shell Objects; Object Communication. The subsequent chapter discussions feature Java, networking components, sockets, API, and distributed objects. Topics include: Using Java from the Shell; Encapsulating the Network with Components; Distributed Objects; Designing an Object-Oriented System; Creating a Shell-Based Distributed Application; Using Shell Objects with CGI; Connecting from the Web.
