  ANNOUNCING: libqcap, context free grammars for network stream parsing

 Topic:          libqcap
 Date:           Thursday, November 30th, 2006
 Time:           6:30pm to 8:30pm (Come a bit early for drinks and snacks)

 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.

 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.

 Note: this topic was announced in October, but the speaker was ill and
