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.
