  • Sniffer Pro Network optimization and troubleshooting handbook
    2002
    Co-Authors: Robert J. Shimonski, Wally Eaton, Umer Khan, Yuri Gordienko
    Abstract:

    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% 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. Only book to offer comprehensive coverage of Sniffer Pro LAN. 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. Up to the Minute Web-based Support. Once the reader understands the concepts of Network hardware, configuration, and implementation, they can receive up-to-the minute links, white papers, and analysis for one year at solutions@syngress.com.

  • Sniffer Pro Network Optimization and Troubleshooting Handbook - Chapter 1 – Introduction to Sniffer Pro
    Sniffer Pro Network Optimization and Troubleshooting Handbook, 2002
    Co-Authors: Robert J. Shimonski, Wally Eaton, Umer Khan, Yuri Gordienko
    Abstract:

    This chapter describes the importance of Network analysis and introduces a Network analyzing software known as Sniffer Pro. Network analysis is a range of techniques that Network engineers and designers employ to study the Properties of Networks, including connectivity, capacity, and performance. Network analysis can be used to estimate the capacity of an existing Network, look at performance characteristics, or plan for future applications and upgrades. A typical Network analyzer understands many Protocols, which enables it to display conversations taking place between hosts on a Network. Network analyzers can capture all the traffic that is going across a Network and interpret the captured traffic to decode and interpret the different Protocols in use. The decoded data is shown in a format that makes it easy to understand. A Network analyzer can also capture only traffic that matches only the selection criteria as defined by a filter. This allows a technician to capture only traffic that is relevant to the Problem at hand. Network analyzers further Provide the ability to create display filters so that a Network Professional can quickly find what he or she is looking for. Advanced Network analyzers Provide pattern analysis capabilities. This feature allows the Network analyzer to go through thousands of packets and identify Problems. The Network analyzer can also Provide possible causes for these Problems and hints on how to resolve them.

  • Sniffer Pro Network Optimization and Troubleshooting Handbook - Chapter 8 – Using Filters
    Sniffer Pro Network Optimization and Troubleshooting Handbook, 2002
    Co-Authors: Robert J. Shimonski, Wally Eaton, Umer Khan, Yuri Gordienko
    Abstract:

    This chapter Provides information about the fundamentals of building filters for Network traffic capture and analysis. One of the common Problems technicians face is how to understand and build filters. It looks easy – patterns are built and offsets are used. In the data transmission environment, filtering becomes very important when it comes to the search and use of specific information hidden in the midst of unimportant data. One of the most difficult and significant tasks involved in working with Sniffer Pro is to define the right filter, which will save a great deal of time when it comes to detecting a Problem on the Network or analyzing data that have been captured using a particular filter. Traffic can be filtered based on Layer 2 and Layer 3 addresses, Protocol types, and/or data patterns. To access and use the predefined filters, a sample Profile has to be copied and saved as a new one. Profiles are special units in which Sniffer Pro stores filters, and each filter has its own Profile. New Profiles can be created from the Monitor, Capture, and Display menus, depending on a type of filter needed. Generally, capture filters are used when, at the moment before capturing starts, the specific data that is needed to analyze is pinpointed and is saved into the capture buffer. One of the advantages of this type of filtering is that only specific information is captured and saved, thus saving space on the hard drive.

  • Sniffer Pro Network Optimization and Troubleshooting Handbook - Chapter 2 – Installing Sniffer Pro
    Sniffer Pro Network Optimization and Troubleshooting Handbook, 2002
    Co-Authors: Robert J. Shimonski, Wally Eaton, Umer Khan, Yuri Gordienko
    Abstract:

    This chapter discusses how to install Sniffer Pro and covers the issues that could be faced while installing and upgrading. The in-depth information focuses on the minimum requirements for every platform. The chapter also describes how to configure the drivers and why special drivers are needed for Ethernet, Token Ring, or any other platform used with Sniffer Pro. Sniffer Pro is as simple as installing any other application on Microsoft Windows and it uses the standard InstallShield Wizard to guide through the setup Process. Promiscuous mode Network cards and drivers should be used to capture traffic. Otherwise, the Sniffer Pro system only sees frames destined for it. To gain most from the system, an NAI-supported NIC with NAI enhanced drivers should be installed. These drivers are optimized for use with Sniffer Pro and Provide the best capture performance as well as the ability to monitor physical layer errors.

  • Sniffer Pro Network Optimization and Troubleshooting Handbook - Chapter 7 – Analyzing Network Issues
    Sniffer Pro Network Optimization and Troubleshooting Handbook, 2002
    Co-Authors: Robert J. Shimonski, Wally Eaton, Umer Khan, Yuri Gordienko
    Abstract:

    This chapter shows that many of the Problems might be masked by other things, but through Sniffer Pro can determine hidden issues or the Problems that might be masked by other things easily. Excessive collisions are studied from an historical perspective and modern day apProach to controlling them is examined. By explaining the functionality of repeaters, hubs, bridges, and switches, these Networking devices' ability to manage collisions have been evaluated. The advantage of full-duplex operation, in-so-far as collisions and bandwidth are concerned. Broadcast traffic, including broadcast domains and the Problem of excessive broadcasts, known as broadcast storms have been explored. Multistation access units (MAUs) have been scrutinized and their ability to automatically repair a broken ring is highlighted. The chapter also covers Dynamic Host Configuration Protocol (DHCP). By demonstrating the powerful ability of Sniffer Pro and its Help functions to be both a tool and a mentor, this chapter seeks to Provide the knowledge and confidence necessary to apProach a Network Problem with a positive attitude and an assurance of success.
