This task-based, visual reference guide uses step-by-step instructions and plenty of screenshots, and includes three years worth of new material based on the latest Unix developments. This reference guide details all Unix commands and options along with tips that put those commands in context. Leading Unix authorities Deborah S. Ray and Eric J. Ray leverage their expertise as technical writers and working in the industry (Sun Microsystems) as they take readers step-by-step through the most common Unix commands and options.

Surveys the best practices for all aspects of system administration, covering such topics as storage management, email, Web hosting, performance analysis, virtualization, DNS, security, and configuration management.

In this updated edition, authors Deborah and Eric Ray use crystal-clear instructions and friendly prose to introduce you to all of today's Unix essentials. You’ll find the information you need to get started with the operating system and learn the most common Unix commands and concepts so that Unix can do the hard work for you. After mastering the basics of Unix, you’ll move on to how to use directories and files, work with a shell, and create and edit files. You’ll then learn how to manipulate files, configure a Unix environment, and run–and even write–scripts. Throughout the book–from logging in to being root–the authors offer essential coverage of Unix.

This book addresses topics in the area of forensic analysis of systems running on variants of the UNIX operating system, which is the choice of hackers for their attack platforms. According to a 2007 IDC report, UNIX servers account for the second-largest segment of spending (behind Windows) in the worldwide server market with $4.2 billion in 2Q07, representing 31.7% of corporate server spending. UNIX systems have not been analyzed to any significant depth largely due to a lack of understanding on the part of the investigator, an understanding and knowledge base that has been achieved by the attacker. The book begins with a chapter to describe why and how the book was written, and for whom, and then immediately begins addressing the issues of live response (volatile) data collection and analysis. The book continues by addressing issues of collecting and analyzing the contents of physical memory (i.e., RAM). The following chapters address /proc analysis, revealing the wealth of significant evidence, and analysis of files created by or on UNIX systems. Then the book addresses the underground world of UNIX hacking and reveals methods and techniques used by hackers, malware coders, and anti-forensic developers. The book then illustrates to the investigator how to analyze these files and extract the information they need to perform a comprehensive forensic analysis. The final chapter includes a detailed discussion of loadable kernel Modules and malware. Throughout the book the author provides a wealth of unique information, providing tools, techniques and information that won't be found anywhere else. This book contains information about UNIX forensic analysis that is not available anywhere else. Much of the information is a result of the author's own unique research and work. The authors have the combined experience of law enforcement, military, and corporate forensics. This unique perspective makes this book attractive to all forensic investigators.

Wouldnt you like to automate the tedious daily tasks of system administration? Automating UNIX and Linux Administration will show you how, by exploring existing tools and offering real-world examples. Although some of the book is Linux-specific, most of the information applies to any UNIX system, including material on automating tasks across multiple variants of UNIX. Author Kirk Bauer briefly overviews tools and technologiesand assumes preliminary knowledge about editing a configuration file or mounting a file system. The techniques, methods, and tools in this book will help you manage a single systembut will prove especially powerful across multiple systems. No matter if the systems are desktops, servers, or Beowulf clustersall of them will benefit from this automation. And managing five to five thousand systems will become a simpler task!

This book is designed to be a shell programmer's reference on Unix and Linux. It covers the commands, syntax, and operators for three major shells used in Unix and Linux; the Bourne Again shell (BASH), the TCSH shell, and the Z-shell. All are enhanced versions of their corresponding original Unix shells. The BASH shell is an advanced version of the Bourne shell, which includes most of the advanced features developed for the Unix Korn shell and C-shells. TCSH is an enhanced version of the C-shell that was originally developed for BSD versions of Unix. The Z-shell is an enhanced version of the Unix Korn shell. The Perl and GAWK shell scripting languages are also presented in detail, examining the use of variables, operators, and control structures to create complex shell programs. In addition the book covers supplementary features like the Make utility and man page formatting. The ebook version features hyper-linked overview, contents, index, tables, chapters, and Web addresses.

There are many objectives and goals to be considered when securing a operating system. When configuring Unix operating system security, consider the critical principles of security known as the confidentiality, integrity, and availability (CIA) triad. In addition to incorporating security controls that relate to the CIA triad, three other security features directly affect CIA and aid the overall site security program: access control, auditing, and backups. Although this chapter covers general Unix considerations, it also addresses several Linux specific items. This chapter is for all Linux variants: file names, directory paths, variable names, and so on, may also have to be taken into consideration. There are numerous versions of Linux, and it would be beyond the scope of this chapter to try to detail them all. All requirements listed within this chapter will pertain to all versions of Linux unless explicitly noted otherwise.
