    This book provides complete information and step-by-step Instructions for analyzing protocols and network traffic on Windows, Unix or Mac OS X networks. First, readers will learn about the types of sniffers available today and see the benefits of using Ethereal. Readers will then learn to install Ethereal in multiple environments including Windows, Unix and Mac OS X as well as building Ethereal from source and will also be guided through Ethereal's graphical user interface. The following sections will teach readers to use command-line options of Ethereal as well as using Tethereal to capture live packets from the wire or to read saved capture files. This section also details how to import and export files between Ethereal and WinDump, Snort, Snoop, Microsoft Network Monitor, and EtherPeek. The book then teaches the reader to master advanced tasks such as creating sub-trees, displaying bitfields in a graphical view, tracking requests and reply packet pairs as well as exclusive coverage of MATE, Ethereal's brand new configurable upper level analysis engine. The final section to the book teaches readers to enable Ethereal to read new Data sources, program their own protocol dissectors, and to create and customize Ethereal reports.

    This book will cover customizing Snort to perform intrusion detection and prevention; Nessus to analyze the network layer for vulnerabilities; and Ethereal to sniff their network for malicious or unusual traffic. The book will also contain an appendix detailing the best of the rest open source security tools. Each of these tools is intentionally designed to be highly customizable so that users can torque the programs to suit their particular needs. Users can code their own custom rules, plug-ins, and filters that are tailor-made to fit their own networks and the threats which they most commonly face. The book describes the most important concepts of coding and customizing tools, and then provides readers with invaluable working scripts that can either be used as is or further refined by using knowledge gained from the book.

    This book provides system administrators with all of the information as well as software they need to run Ethereal Protocol Analyzer on their networks. There are currently no other books published on Ethereal, so this book will begin with chapters covering the installation and configuration of Ethereal. From there the book quickly moves into more advanced topics such as optimizing Ethereal's performance and analyzing data output by Ethereal. Ethereal is an extremely powerful and complex product, capable of analyzing over 350 different network protocols. As such, this book also provides readers with an overview of the most common network protocols used, as well as analysis of Ethereal reports on the various protocols. The last part of the book provides readers with advanced information on using reports generated by Ethereal to both fix security holes and optimize network performance. Provides insider information on how to optimize performance of Ethereal on enterprise networks. Book comes with a CD containing Ethereal, Tethereal, Nessus, Snort, ACID, Barnyard, and more! Includes coverage of popular command-line version, Tethereal.

  • PyAnnolib

    - Present

    PyAnnolib is a Python library to read the "annotation" file produced by Electric Cloud's "Electric Accelerator" (emake) product. It lets you use Python to analyze your builds and to extract very low-level information about your builds, like the complete file dependency graph. This project also includes report scripts to present useful errors to end users, to analyze conflicts, and to calculate a histogram of the parallelism seen during a build ("what % of the time were N agents running at a…

  • Instmake

    - Present

    I developed instmake over many years at Cisco, and received permission to release it as open source.

    Instmake is a Python-based tool which embeds itself as the shell used during the run of GNU make. By doing this it can record every command executed during a build, along with data about that command. The resulting log file is much more detailed than the traditional output of GNU make. The log files can be analyzed to investigate what happened during the build.

    Wrote a C++ library for reading FOCUS database files.
    Wrote C++-based analysis programs making use of this library, which ran faster than the equivalent FOCUS programs.
