Essential System Administration ,3rd Edition is the definitive guide for Unix system administration, covering all the fundamental and essential tasks required to run such divergent Unix systems as AIX, FreeBSD, HP-UX, Linux, Solaris, Tru64 and more. It describes all the usual administrative tools that Unix provides, but it also shows how to use them intelligently and efficiently.Whether you use a standalone Unix system, routinely provide administrative support for a larger shared system, or just want an understanding of basic administrative functions, Essential System Administration is for you. She has written eight books, including Essential System Administration (now in its third edition), Essential Windows NT System Administration and the Windows 2000 Desktop Reference (all from O'Reilly Media, Inc.) and Exploring Chemistry with Electronic Structure Methods (Gaussian, Inc.).

Their perspective on the variations among systems is valuable for anyone who runs a heterogeneous computing facility.”. The twentieth anniversary edition of the world’s best-selling UNIX system administration book has been made even better by adding coverage of the leading Linux distributions: Ubuntu, openSUSE, and RHEL. It details best practices for every facet of system administration, including storage management, network design and administration, email, web hosting, scripting, software configuration management, performance analysis, Windows interoperability, virtualization, DNS, security, management of IT service organizations, and much more. Trent holds a BS in Computer Science from the University of Colorado.

What DNS does, how it works, and when you need to use it How to find your own place in the Internet's namespace Setting up name servers Using MX records to route mail Configuring hosts to use DNS name servers Subdividing domains (parenting) Securing your name server: restricting who can query your server, preventing unauthorized zone transfers, avoiding bogus servers, etc. Cricket was hostmaster@hp.com for over three years, and then joined HP's Professional Services Organization to co-found HP's Internet Consulting Program.Cricket left HP in 1997 to form Acme Byte & Wire, a DNS consulting and training company, with his friend Matt Larson. Since then Paul has worked on various HP products during his 19 year career: HP JetDirect software, HP OfficeJet fax firmware, HPPhoto web site, and HP Photosmart Premier software.Paul and his wife Katherine live in San Diego California with their two cats, Gracie and Tiffany.

But whether you are a newcomer or a Unix power user, you'll find yourself thumbing through the goldmine of information in the new edition of Unix Power Tools to add to your store of knowledge. The book includes articles abstracted from other O'Reilly books, new information that highlights program tricks and gotchas, tips posted to the Net over the years, and other accumulated wisdom.Affectionately referred to by readers as "the" Unix book, UNIX Power Tools provides access to information every Unix user is going to need to know. This detail-filled book distinguishes itself from other guides for Unix gurus with its organizational structure (it's a series of articles that can be absorbed sequentially or individually) and carefully designed and executed index. Topics covered: How to work efficiently, elegantly, and creatively with the Unix tool suite, as well as (to a lesser extent) with Perl and Python scripts.

An all-new chapter on kernel data structures Details on interrupt handlers and bottom halves Extended coverage of virtual memory and memory allocation Tips on debugging the Linux kernel In-depth coverage of kernel synchronization and locking Useful insight into submitting kernel patches and working with the Linux kernel community.

In addition, the book presents RMON 1 and RMON 2 enhancements, looking at statistics collection, alarms, and filters, as well as the extensions to RMON 1 for RMON 2 devices. Gone are the days when an organization would rely on a single vendor and a relatively straightforward architecture to support its needs. Today's typical organization has a large and growing but amorphous architecture, with a variety of local area networks (LANs) and wide area networks (WANs), supported by bridges and routers, and a variety of distributed computing services and devices, including PCs, workstations, and servers. Fundamental to the operation of such tools and applications in a multivendor environment are standardized techniques for representing and exchanging information relating to network management. In response to these needs, managers and users have turned overwhelmingly to one standard: SNMP and the related RMON specification. Part I of the book is a survey of network management technology and techniques, to enable the reader to place the various vendor offerings into the context of his or her requirements. Part II presents the original SNMP family of standards, which is still the most widely deployed version. I would also like to thank the following reviewers, who generously provided feedback on part or all of the second edition: K. K. Ramakrishnan of AT&T, Russell Dietz of Technically Elite Concepts, Ravi Prakash of FTP Software, Ole Jacobsen of Cisco, Cliff Baker of the Research Libraries Group, Sandra Durham of Cisco, and Ian Taylor of Cygnus. In addition, I am grateful to the people who reviewed the original proposal for this book, and an early draft: Lyman Chapin of BBN, Radia Perlman of Novell, Glen Glater and Christopher Heigham of Midnight Networks, and Peter Schmidt of Midnight Networks.

Each of the eleven chapters presents topics in an easy to understand manner and includes real-world examples of security principles in action. The author uses many of the same analogies and explanations he’s honed in the classroom that have helped hundreds of students master the Security+ content. You’ll understand the important and relevant security topics for the Security+ exam, without being overloaded with unnecessary details. An accomplished author and professional trainer, Darril Gibson has authored or coauthored more than 30 books.

Since different candidates have different time constraints, EPI includes a study guide with several scenarios, ranging from weekend Hackathon to semester long preparation with a recommended a subset of problems for each scenario. All problems are classified in terms of their difficulty level and include many variants to help you apply what you have learned more widely. It emphasizes problems that stem from real-world applications and can be coded up in a reasonable time, and is a wonderful complement to a traditional computer science algorithms and data structures course."
