Map: http://tinyurl.com/cd6l WHAT IS IT? ~~~~~~~~~~~ This is one of a series of Linux/Open-Source Technology Seminars to be presented by the Ottawa Canada Linux Users Group (OCLUG) and ExitCertified. ExitCertified has generously made their classroom space available to OCLUG for these training sessions and other events. WHAT IS THIS MONTH'S TOPIC? ~~~~~~~~~~~~~~~~~~~~~~~~~~~ Packets for streaming network protocols are usually handled with hand-written parsers. Those parsers can be error prone, insecure, slow, and hard to maintain. This talk will introduce the idea of using context free grammars to build network parsers, and present libqcap, an experimental library for parsing all levels of the network stack including IP, TCP, and any streaming protocol. You can learn more about libqcap from http://qcap.sf.net/. Note: this topic was announced in October, but the speaker was ill and unable to give the talk. He is better now. ABOUT THE INSTRUCTOR ~~~~~~~~~~~~~~~~~~~~ Evan Hughes is a recent graduate of Carleton University's Masters of Computer Science Program. He has spent the past six years working in and around industry and doing academic research. REGISTRATION ~~~~~~~~~~~~ Registration for this class is on a first-come, first-served basis.
