Integrated Cisco and UNIX Network Architectures reveals not just the feasibility but also the desirability of Cisco/UNIX integrated routing with regard to systems integration, interoperability, and feature requirements. Detailed, progressively complex lab scenarios emphasize enterprise and ISP requirements, casting light on the similarities and differences of these two worlds. Platform issues, such as behavior of firewall filters, kernel features, and proper standards compliance, are discussed, analyzed with sniffers, and tested with handcrafted traffic from packet generators and test applications.

“The network is the computer.” More than a catchy phrase, this slogan (which Sun coined more than a dozen years ago) describes a fundamental reality of computing today: The location of data, processing, and services are not as important as how and when these resources are used. With advances in the Web, we might even say, “The Internet is the computer.” The systems we manage have evolved into portals to a universe of information and tools. Basic software applications are increasingly Internet-, intranet-, and Web-centric. This was true when this book was first published in the year 2000. It is even more true today with the proliferation of network storage and service-centric computing.

But how do we manage our systems and networks to best effect this reality? How do we keep our systems and networks manageable? What kind of foundation do we need to build locally so that the layers of complication wrought by services provided internally and externally go down smoothly and reliably? What kind of skills do we need to manage an increasingly virtual network? Our users are sending e-mail around the globe. Our networks comprise ever-changing configurations of new and aging systems. We are seeing both data and system services becoming disassociated from the server hardware. Our responsibilities as systems administrators now often incorporate managing clusters, configuring networks, monitoring security, Webmastering, performance analysis, and debugging, in addition to the standard fare of software installation, account and printer management, and backups.

Everything in this book is intended to move you in the direction of the manageable network—to introduce you to tools and provide you with strategies that will help you manage your systems.

No one can manage infinite complexity. And, if anyone could, that person would likely be smart enough or “interesting” enough that he or she wouldn’t want to. Those of us who have been in the business of managing large networks for a long time understand that it is far easier to manage several hundred systems that are all the same than half a dozen that are all different. These two scenarios represent opposite ends of the spectrum with respect to homogeneity and heterogeneity. However, most of us are managing networks of systems that are somewhere in between these all-the-same and all-different models. Regardless of where you sit on the spectrum, you will find that your job will be easier and your life more pleasant in direct proportion to the degree of uniformity you can introduce into the environment that you manage. The more you can configure systems and services more or less identically, the easier a time you will have in every phase of managing them—from installation to backups.

At the same time, the move toward highly available services and virtual computing mandates a dramatic change in the way that we will do our jobs. Solaris 9 is more than just another release of Sun’s operating environment. Solaris 9 represents a major shift of focus. Incorporating directory services and serious security tools (e.g., SSH, RBAC and the Sun Screen firewall) along with major new management tools, Solaris 9 will make your job much better or much worse, but clearly different. With enough insight and preparation, you will probably love this new release of Solaris.

Of all the strategies that we suggest to you within the pages of this book, the best is one that we’ve borrowed from the Boy Scouts: Be prepared. Regardless of how carefully and wisely you lay out your network and configure your systems and services, something will break. Adopting a policy of planning for disaster and of thinking through all the what-if scenarios that you can imagine will help reduce your stress as well as your downtime when one of these disasters actually happens. With respect to highly available services, preparing for disaster boils down to knowing how to manage and monitor HA services. Though we anticipate a steeply sloped learning curve for systems administrators coming up to speed on Solaris 9, we also have confidence that the plateau will be long and flat. Our networks will be easier to manage and our tasks less tedious.

Disillusioned, I did what many other people did: I read the backup chapters in several system and database administration books. Even the best books covered it on only a cursory level, and none of them told me how to automate the backups of 200 Unix machines that ran eight different flavors of Unix and three different database products. Another common problem with these chapters is that they would dedicate 90 percent or more to backup and less than 10 percent to recovery. So my company did what many others had done before us-we reinvented the wheel and wrote our own homegrown utilities and procedures.

Then one day I realized that our backup/recovery needs had outgrown our homegrown utilities, which meant that we needed to look at purchasing a commercial utility. Again, there were no resources to help explain the differences between the various backup utilities that were available at that time, so we did what most people do-we talked to the vendors. Since most of the vendors just bashed one another, our job was to try to figure out who was telling the truth and who wasn’t. We then wrote a Request For Information (RFI) and a Request For Proposal (RFP) and sent it to the vendors we were considering, whose quotes ranged from

To achieve this goal, the book gives equal weight to UNIX systems and network concepts and their practical implementations. During the many years that I have worked as a computer hardware designer and programmer, and most recently as a UNIX administrator, I have tackled many practical UNIX and network problems. Working for different employers, I faced real?life situations in an academic environment, in the financial industry and the retail industry, and on the Internet. At the same time, while teaching at New York University and Columbia University, I met many novices in this field and learned an optimal and quick way to teach UNIX administration. This accumulated knowledge and experience have helped me to select UNIX topics that are of the utmost relevance to successful administration, and those topics served as the basis for this book. Some additional UNIX topics, significant from a historical point of view, or necessary for an overall presentation of UNIX administration, are also included. In concert, they create a logical and comprehensive text, easy to read and follow. It is impossible to say that everything existing in the UNIX administration arena is covered here ? it would be impossible to put it all in a single book. However, the principal and most important UNIX administrative topics that make a complete UNIX administration environment and a sufficient base for overall UNIX management are fully explored.

Still a lot of work is required to finish this short introduction to NetBSD: some chapters are not finished (some are not even started) and some subjects still need testing (yes, a guide must also be tested). I?ll try to work on it and improve it in my spare time but if you want to help, you?re welcome: you can write new chapters (or parts of) or send corrections for existing subjects.

Today, the ANSI C++ programming language is widely used throughout the world in both academia and industry. In many educational institutions it is the language of choice for a first programming course and for a language to be used for computer science instruction. A key reason for this is that C++ has drifted down the curriculum from more advanced courses to more introductory courses. Further, C++ comes with many useful libraries, and is supported by sophisticated integrated environments. It is a language that efficiently supports object-oriented programming (OOP) the dominant contemporary programming methodology.

C++ by Dissection presents a thorough introduction to the programming process by carefully developing working programs to illuminate key features of the C++ programminglanguage. Program code is explained in an easy-to-follow, careful manner throughout.The code has been tested on several platforms and is found on the bundled CDrom accompanying this text. The code in C++ By Dissection can be used with most C++ systems, including those found in operating systems such as MacOS, MS-DOS, OS/2, UNIX, and Windows.

C++, invented at Bell Labs by Bjarne Stroustrup in the mid-1980s, is a powerful, modern, successor language to C. C++ adds to C the concept of class, a mechanism for providing user-defined types, also called abstract data types. C++ supports object-oriented programming by these means and by providing inheritance and runtime type binding.
