Those of you who run networks on Windows 2000 know the benefits of using Active Directory for managing user information and permissions. You also know what a bear it can be. The newer version included with Windows Server 2003 has over 100 new and updated features to simplify deployment, but once it's in place many system administrators still find Active Directory challenging. If you're among those looking for practical hands-on support, help is here with our new Active Directory Cookbook for Windows Server 2003 & Windows 2000, a unique problem-solving guide that offers quick answers for both versions of the directory. The book contains hundreds of step-by-step solutions for both common and uncommon problems that you might encounter with Active Directory on a daily basis--including recipes to deal with the Lightweight Directory Access Protocol (LDAP), multi-master replication, Domain Name System (DNS), Group Policy, the Active Directory Schema, and many other features. Author Robbie Allen, a Senior Systems Architect at Cisco Systems and co-author of our Active Directory tutorial, based this collection of troubleshooting recipes on his own experience, along with input from Windows administrators throughout the industry. Each recipe includes a discussion to explain how and why the solution works, so you can adapt the problem-solving techniques to similar situations.

Local-area networks (LANs) are becoming increasingly congested and overburdened because of a dramatic increase in traffic, faster CPUs and operating systems, and more network-intensive applications. Many organizations that use network and computing technology use LAN switching to take advantage of high-speed traffic forwarding and improved performance of traditional Ethernet technologies that don't require costly wiring upgrades or time-consuming host reconfiguration. Cisco LAN Switching Fundamentals provides administrators of campus networks with the most up-to-date introduction to LAN switching within a traditional Ethernet environment.

Whether you need a network of ten Linux PCs and a server or a datacenter with a few thousand Unix nodes, you need to know how to automate much of the installation, configuration, and standard system administration. Build your network once using cfengine, and the network build will work, without user intervention, on any hardware you prefer.Automating Linux and Unix System Administration, Second Editionis unique in its focus on how to make the system administrator's job easier and more efficient: instead of just managing the system administrator's time, the book explains the technology to automate repetitive tasks and the methodology to automate successfully. Both new and seasoned professionals will profit from industry–leading insights into the automation process. System administrators will attain a thorough grasp of cfengine, kickstart, and shell scripting for automation. After reading all chapters and following all exercises in this book, the reader will be able to set up anything from a Linux datacenter to a small office network. What you'll learn See how to make changes on many UNIX and Linux hosts at once in a reliable and repeatable manner. Learn how to automate things correctly so you only have to do it once, by leveraging the authors' experience in setting up small, medium, and large networks. Set up a Linux datacenter or a network correctly. Explore handling real–world environments where not all hosts are configured alike via a case study of a fictional new datacenter buildout. Examine real–world examples for core infrastructure services (DNS, mail, monitoring, log analysis, security, cfengine, imaging) to build on in your environment. Understand core system administration best practices, which are a key part of how cfengine and automations deployments are outlined in the book. Learn how to make changes reversible, repeatable, and correct the first time through interaction with product/application stakeholders (programmers, product managers, customers, etc.). Who this book is for This book is for Linux system administrators who want to learn about the software and methodology to automate repetitive tasks-regardless of network or datacenter size-in one place. System managers will also find it much easier to think about network technology and automation projects if they read this book.

In Natural Ethical Facts William Casebeer argues that we can articulate a fully naturalized ethical theory using concepts from evolutionary biology and cognitive science, and that we can study moral cognition just as we study other forms of cognition. His goal is to show that we have "softly fixed" human natures, that these natures are evolved, and that our lives go well or badly depending on how we satisfy the functional demands of these natures. Natural Ethical Facts is a comprehensive examination of what a plausible moral science would look like.Casebeer begins by discussing the nature of ethics and the possible relationship between science and ethics. He then addresses David Hume's naturalistic fallacy and G. E. Moore's open-question argument, drawing on the work of John Dewey and W. V. O. Quine. He then proposes a functional account of ethics, offering corresponding biological and moral descriptions. Discussing in detail the neural correlates of moral cognition, he argues that neural networks can be used to model ethical function. He then discusses the impact his views of moral epistemology and ontology will have on traditional ethical theory and moral education, concluding that there is room for other moral theories as long as they take into consideration the functional aspect of ethics; the pragmatic neo-Aristotelian virtue theory he proposes thus serves as a moral "big tent." Finally, he addresses objections to ethical naturalism that may arise, and calls for a reconciliation of the sciences and the humanities. "Living well," Casebeer writes, "depends upon reweaving our ethical theories into the warp and woof of our scientific heritage, attending to the myriad consequences such a project will have for the way we live our lives and the manner in which we structure our collective moral institutions."

More than a million systems are now connected to the Internet, and something like 15 million people in 100 countries on all seven continents use Internet services. More than 100 million email messages are exchanged each day, along with countless files, documents, and audio and video images. Everyone is jumping on the Internet bandwagon. Once a haven for academicians and scientists, the Net is now reaching large and small businesses, government at all levels, school children, and senior citizens. The commercial world is rushing headlong into doing business on the Internet, barely pausing while technologies and policies catch up with their desire to go online. But, too few of the seekers after Internet wisdom and riches consider whether their businesses will be safe on the Net. What kinds of security risks are posed by the Internet? Some risks have been around since the early days of networking -- password attacks (guessing them or cracking them via password dictionaries and cracking programs), denial of service, and exploiting known security holes. Some risks are newer and even more dangerous -- packet sniffers, IP (Internet Protocol) forgery, and various types of hijacking attacks. Firewalls are a very effective way to protect your system from these Internet security threats. Firewalls in computer networks keep damage on one part of the network (e.g., eavesdropping, a worm program, file damage) from spreading to the rest of the network. Without firewalls, network security problems can rage out of control, dragging more and more systems down. What is a firewall? It's a hardware and/or software solution that restricts access from your internal network to the Internet -- and vice versa. A firewall may also be used to separate two or more parts of your local network (for example, protecting finance from R&D). The firewall is installed at the perimeter of the network, ordinarily where it connects to the Internet. You can think of a firewall as a checkpoint; all traffic, incoming and outgoing, is stopped at this point. Because it is, the firewall can make sure that it is acceptable. "Acceptable" means that whatever is passing through -- email, file transfers, remote logins, NFS mounts, etc. -- conforms to the security policy of the site. Building Internet Firewalls is a practical guide to building firewalls on the Internet. If your site is connected to the Internet, or if you're considering getting connected, you need this book. It describes a variety of firewall approaches and architectures and discusses how you can build packet filtering and proxying solutions at your site. It also contains a full discussion of how to configure Internet services (e.g., FTP, SMTP, Telnet) to work with a firewall. The book also includes a complete list of resources, including the location of many publicly available firewall construction tools. The book is divided into four parts: Part I discusses Internet threats, the benefits of firewalls, overall security strategies, and a summary of Internet services and their security risks. Part II describes possible firewall designs and general terms and concepts, how to protect the bastion host in your firewall configuration, how to build proxying and packet filtering firewalls, and how to configure Internet services to operate with a firewall. Part III describes how to maintain a firewall, develop a security policy, and respond to a security incident. Part IV contains appendic

Considering Europe as a whole rather than as a mosaic of individual states, François Crouzet presents here an accessible, engaging history of the European economy during the second millennium. Stressing the common economic institutions shared over time by the different regions of Europe and the networks of relations that have linked them, Crouzet examines pan-European changes and integration rather than merely the particular experiences of individual countries. A History of the European Economy, 1000-2000 goes beyond addressing the historical ramifications of trade in the European economy to encompass problems such as the diffusion of technology, the migration of capital and labor, diasporas and minorities, and national diversity. By stressing the historical origins of the drive toward European integration and its progress all the way to the birth of the euro, Crouzet delivers an original and comprehensive overview of European economic history.
