The only book dedicated Sniffer, a powerful tool created for real-time enterprise network fault diagnosis and performance management. "Sniffer Network Optimization and Troubleshooting Handbook" introduces the reader to the vast functionality of the suite of Sniffer Solutions from Network Associates but ultimately focuses on the affordable and most widely used Sniffer Product - Sniffer Pro LAN Network Analyzer. This book will begin with the basic features of Sniffer Pro LAN and then move the reader through the impressive tips and tools available for gathering data, analyzing, troubleshooting, resolving and securing problems on their network. In today's day and age a company is judged by the quality of it is network. To ensure sustained network performance and to avoid costly network downtime, network administrators need to be proficient with advanced networking monitoring and troubleshooting solutions, like Sniffer, to be able to detect, observe, and resolve network problems before these problems impact users or customers. Sniffer from Network Associates is a suite of tools including Sniffer Portable Analysis Suite, Sniffer Distributed Analysis Suite, Sniffer Reporting, Sniffer Optical, and Sniffer Wireless. With a clear market leadership, Sniffer Solutions are employed in over 80 per cent of the enterprise networks of the Fortune 100. Sniffer has also received wide industry acclaim from the experts and its everyday users. In 2000 Sniffer was named one of the 10 most computer products of the decade by "Network Computing Magazine". It also received the "Editor's Choice" award from "PC Magazine" during the second quarter of 2001. Over 60,000 individuals have taken advantage of the educational services offered by Sniffer Technologies - aptly named Sniffer University. Coupled with the introduction of the Sniffer Certified Professional Program (SCPP) as a replacement for the popular CNX (Certified Network Expert) certification, an aptitude with Sniffer Solutions is a "must-have" for system administrators. This is the only book to offer comprehensive coverage of Sniffer Pro LAN. It also provides supplemental study materials for the SCPP certification track. As of April 2001, the CNX certifications track became inactive. Current CNXs looking to update their certifications to the new SCPP track are going to need to bring themselves up to speed on the new offerings from the Sniffer family of products before desertification.
