 By: Gary A. Donahue List Price: $44.99 Amazon Price: $29.69 Editorial Review: Written by networking veteran with 20 years of experience, Network Warrior provides a thorough and practical introduction to the entire network infrastructure, from cabling to the routers. What you need to learn to pass a Cisco certification exam such as CCNA and what you need to know to survive in the real world are two very different things. The strategies that this book offers weren 't on the exam, but they 're exactly what you need to do your job well. Network Warrior takes you step by step through the world of hubs, switches, firewalls, and more, including ways to troubleshoot a congested network, and when to upgrade and why. Along the way, you 'll gain an historical perspective of various networking features, such as the way Ethernet evolved. Based on the author 's own experience as well as those he worked for and with, Network Warrior is a Cisco-centric book, focused primarily on the TCP/IP protocol and Ethernet networks -- the realm that Cisco Systems now dominates. The book covers: The type of networks now in use, from LANs, WANs and MANs to CANs The OSI Model and the layers involved in sending data Hubs, repeaters, switches, and trunks in practice Auto negotiation and why it 's a common problem in network slowdowns Route maps, routing protocols, and switching algorithms in Cisco routers The resilient Ethernet -- how to make things truly redundant Cisco 6500 multi-layer switches and the Catalyst 3750 switch Telecom nomenclature -- why it 's different from the data world T1 and DS3 Firewall theory, designing access lists, authentication in Cisco devices Server load balancing technology Content switch module in action Designing QOS and what QOS does not do IP design and subnetting made easy The book also explains how to sell your ideas to management, how networks become a mess as a company grows, and why change control is your friend. Network Warrior will help network administrators and engineers win the complex battles they face every day.

By: Cricket LiuPaul Albitz List Price: $49.99 Amazon Price: $31.49 Editorial Review: This is the definitive book on the Domain Name System (DNS), the powerful scheme that facilitates the translation of English-like domain names (www.amazon.com) into computer-comprehensible Internet Protocol (IP) addresses (208.216.182.15). If you run a DNS server of any kind, particularly under Unix, you need to have this book on hand. This book's early chapters give a view of DNS from high altitude, explaining basic concepts such as domains, name servers, and name resolution. From there, the authors proceed on a more practical tack, presenting specific instructions for setting up your own domain and DNS server using BIND. The authors then tell you what to do as your domain grows and you need to add more machines, subdomains, and greater throughput capacity. They also talk a lot about nslookup and C programming with the various DNS and BIND libraries. Administrators will find the chapter on BIND debugging output particularly helpful. Here, the authors translate BIND's mysterious error messages and offer specific strategies for fixing and optimizing the program. This edition covers BIND 8.1.2, but pays lots of attention to older versions that are still in wide use (4.8.3 and 4.9). The authors are careful to note differences among the versions. --David Wall DNS and BIND tells you everything you need to work with one of the Internet's fundamental building blocks: the distributed host information database that's responsible for translating names into addresses, routing mail to its proper destination, and even listing phone numbers with the new ENUM standard. This book brings you up-to-date with the latest changes in this crucial service. The fifth edition covers BIND 9.3.2, the most recent release of the BIND 9 series, as well as BIND 8.4.7. BIND 9.3.2 contains further improvements in security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework). Whether you're an administrator involved with DNS on a daily basis or a user who wants to be more informed about the Internet and how it works, you'll find that this book is essential reading. Topics include: 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. The DNS Security Extensions (DNSSEC) and Transaction Signatures (TSIG) Mapping one name to several servers for load sharing Dynamic updates, asynchronous notification of change to a zone, and incremental zone transfers Troubleshooting: using nslookup and dig, reading debugging output, common problems DNS programming using the resolver library and Perl's Net::DNS module By: Lee Holmes List Price: $49.99 Amazon Price: $31.49 Editorial Review: This Cookbook by Windows PowerShell team developer Lee Holmes provides hundreds of tested scripts that you can use right away to get Microsoft's new tool working for you.
