jNetStream For Linux

jNetStream is a protocol analyzer and a sniffer. A set of applications and complete Java library are provided with a comprehensive API.

Hundreds of protocols have been defined, and the list can be expanded with a simple NPL language. It is appropriate for custom protocol development, grad students, and network teachers/professors.

Supplied applications provide all of the common functionality you may expect from a packet sniffer:

*) slydecoder - a packet decoder that is extremely flexible. -> group packets by flows (-g option). i.e. TCP stream will be grouped into a flow -> you have the option to supply your own protocol definitions -> decode multiple files at once -> decode different types of capture files at once -> most powerful filter engine available

*) slycopy - capture (or trace) file manipulator -> merge multiple capture files into single output file -> merge multiple capture files even if they are of different types -> apply filters during the manipulation -> In the future you will be able to modify packets during copy (i.e. remove a specific header from packets such as decapsulate VLANs)

*) Also you can execute both of these applications using java runtime environment like this: -> java -jar JNetStream.jar com.voytechs.jnetstream.tools.SlyDecoder

-> java -jar JNetStream.jar com.voytechs.jnetstream.tools.SlyCopy

Or shorthand for SlyDecoder using the default main class: -> java -jar JNetStream.jar

Note: /opt/jnetstream directory is the default installation directory, if you install JNetStream into a different directory adjust the base dir name appropriately.

What's New in This Release:

� This release introduces a number of new features and bugfixes. � NPL protocol definitions are now only loaded on demand and allow user-definable binding overrides. � New packet counting options have been added which run under several different models, including a statistical model. � Packets can be counted in very large, multi-gig files quickly. � Lots of logging (Apache CommonsLogging and Log4j) has been added.
