A modern computer system that's not part of a network is even more of an anomaly today than it was when we published the first edition of this book in 1991. But however widespread networks have become, managing a network and getting it to perform well can still be a problem. Managing NFS and NIS, in a new edition based on Solaris 8, is a guide to two tools that are absolutely essential to distributed computing environments: the Network Filesystem (NFS) and the Network Information System (formerly called the "yellow pages" or YP). The Network Filesystem, developed by Sun Microsystems, is fundamental to most Unix networks. It lets systems ranging from PCs and Unix workstations to large mainframes access each other's files transparently, and is the standard method for sharing files between different computer systems. As popular as NFS is, it's a "black box" for most users and administrators. Updated for NFS Version 3, Managing NFS and NIS offers detailed access to what's inside, including: * How to plan, set up, and debug an NFS network * Using the NFS automounter * Diskless workstations * PC/NFS * A new transport protocol for NFS (TCP/IP) * New security options (IPSec and Kerberos V5) * Diagnostic tools and utilities * NFS client and server tuning NFS isn't really complete without its companion, NIS, a distributed database service for managing the most important administrative files, such as the passwd file and the hosts file. NIS centralizes administration of commonly replicated files, allowing a single change to the database rather than requiring changes on every system on the network. If you are managing a network of Unix systems, or are thinking of setting up a Unix network, you can't afford to overlook this book.

Andrei Tarkovsky is the most celebrated Russian filmmaker since Eisenstein, and one of the most important directors to have emerged during the 1960s and 70s. Although he made only seven features, each one was a major landmark in cinema, the most well-known of them being the mediaeval epic Andrei Rublev - widely regarded as one of the greatest films of all time - and the autobiographical Mirror, set during the Russia of Stalin's purges in the 1930s and the years of stagnation under Brezhnev. Both films landed Tarkovsky in considerable trouble with the authorities, and he gained a reputation for being a tortured - and ultimately martyred - filmmaker. Despite the harshness of the conditions under which he worked, Tarkovsky built up a remarkable body of work. He burst upon the international scene in 1962 with his debut feature Ivan's Childhood, which won the Golden Lion at Venice and immediately established him as a major filmmaker. During the 1970s, he made two classic ventures into science-fiction, Solaris, regarded at the time as being the Soviet reply to Kubrick's 2001: A Space Odyssey and later remade by Steven Soderbergh, and Stalker, which was thought to have predicted the Chernobyl disaster. Harassed at home, Tarkovsky went into exile and made his last two films in the West, where he also published his classic work of film and artistic theory, Sculpting in Time. Since his death in Paris in 1986, his reputation continued - and continues - to grow. Sean Martin considers the whole of Tarkovsky's oeuvre, from the classic student film The Steamroller and the Violin, across the full-length films, to the later stage works and Tarkovsky's writings, paintings and photographs. Martin also seeks to demystify Tarkovsky as a 'difficult' director, whilst also celebrating his radical aesthetic of long takes and tracking shots, which Tarkovsky was to dub 'imprinted' or 'sculpted' time, and to make a case for Tarkovsky's position not just as an important filmmaker, but also as an artist who speaks directly about the most important spiritual issues of our time.

FreeBSD and OpenBSD are increasingly gaining traction in educational institutions, non-profits, and corporations worldwide because they provide significant security advantages over Linux. Although a lot can be said for the robustness, clean organization, and stability of the BSD operating systems, security is one of the main reasons system administrators use these two platforms. There are plenty of books to help you get a FreeBSD or OpenBSD system off the ground, and all of them touch on security to some extent, usually dedicating a chapter to the subject. But, as security is commonly named as the key concern for today's system administrators, a single chapter on the subject can't provide the depth of information you need to keep your systems secure. FreeBSD and OpenBSD are rife with security "building blocks" that you can put to use, and Mastering FreeBSD and OpenBSD Security shows you how. Both operating systems have kernel options and filesystem features that go well beyond traditional Unix permissions and controls. This power and flexibility is valuable, but the colossal range of possibilities need to be tackled one step at a time. This book walks you through the installation of a hardened operating system, the installation and configuration of critical services, and ongoing maintenance of your FreeBSD and OpenBSD systems. Using an application-specific approach that builds on your existing knowledge, the book provides sound technical information on FreeBSD and Open-BSD security with plenty of real-world examples to help you configure and deploy a secure system. By imparting a solid technical foundation as well as practical know-how, it enables administrators to push their server's security to the next level. Even administrators in other environments--like Linux and Solaris--can find useful paradigms to emulate. Written by security professionals with two decades of operating system experience, Mastering FreeBSD and OpenBSD Security features broad and deep explanations of how how to secure your most critical systems. Where other books on BSD systems help you achieve functionality, this book will help you more thoroughly secure your deployments.

System Performance Tuning answers one of the most fundamental questions you can ask about your computer: How can I get it to do more work without buying more hardware? In the current economic downturn, performance tuning takes on a new importance. It allows system administrators to make the best use of existing systems and minimize the purchase of new equipment. Well-tuned systems save money and time that would otherwise be wasted dealing with slowdowns and errors. Performance tuning always involves compromises; unless system administrators know what the compromises are, they can't make intelligent decisions. Tuning is an essential skill for system administrators who face the problem of adapting the speed of a computer system to the speed requirements imposed by the real world. It requires a detailed understanding of the inner workings of the computer and its architecture. System Performance Tuning covers two distinct areas: performance tuning, or the art of increasing performance for a specific application, and capacity planning, or deciding what hardware best fulfills a given role. Underpinning both subjects is the science of computer architecture. This book focuses on the operating system, the underlying hardware, and their interactions. Topics covered include: *Real and perceived performance problems, introducing capacity planning and performance monitoring (highlighting their strengths and weaknesses). *An integrated description of all the major tools at a system administrator's disposal for tracking down system performance problems. *Background on modern memory handling techniques, including the memory-caching filesystem implementations in Solaris and AIX. Updated sections on memory conservation and computing memory requirements. *In depth discussion of disk interfaces, bandwidth capacity considerations, and RAID systems. *Comprehensive discussion of NFS and greatly expanded discussion of networking. *Workload management and code tuning. *Special topics such as tuning Web servers for various types of content delivery and developments in cross-machine parallel computing For system administrators who want a hands-on introduction to system performance, this is the book to recommend.
