Stop waiting for the network team! If basic TCP/IP was hard, network administrators couldn't do it. Servers give sysadmins a incredible visibility into the network-once they know how to unlock it. Most sysadmins don't need to understand window scaling, or the differences between IPv4 and IPv6 echo requests, or other intricacies of the TCP/IP protocols. You need only enough to deploy your own applications and get easy support from the network team. This book teaches you: * How modern networks really work * The essentials of TCP/IP * The next-generation protocol, IPv6 * The right tools to diagnose network problems, and how to use them * Troubleshooting everything from the physical wire to DNS * How to see the traffic you send and receive * Connectivity testing * How to communicate with your network team to quickly resolve problems A systems administrator doesn't need to know the innards of TCP/IP, but knowing enough to diagnose your own network issues transforms a good sysadmin into a great one.

"Principles of Network and System Administration" focuses on the general principles involved in setting up, configuring and maintaining computer communities, and provides a conceptual overview of the subject. A robust discipline of System Administration is now coming of age and both academics and industry recognize the need to formalize the problems which system administrators tackle. Amongst these challenges are the need to design a network which is logical, efficient, easy to upgrade and secure. The system administrator also needs to keep track of the ever increasing amount of information, to ensure that problems are fixed quickly, and provide a comfortable environment for users. The breadth and complexity involved in adopting and integrating ever more sophisticated technology is covered in this greatly expanded new edition. Whilst providing practical illustrations of technical specifics through examples, Burgess steers away from the overwhelming details of specific operating systems. Trainee administrators and students alike need to understand a wealth of issues relating to heterogeneous environments before understanding the quirks of any one particular system. Moreover this book teaches good practice for working in a global community of networked machines and organizations ? which extends beyond being technically savvy to being professionally and ethically responsible. Features: Broad coverage of Linux and other Unix versions, Windows, Macs and mainframes.Practical - supplemented with reference section containing practical recipes and advice.Vendor/Platform independent view of the technical, theoretical, practical and social/ethical aspects to Systems Administration.Strong pedagogy - end of chapter exercises plus teaching guide available from Website.
