jNetStream Description
jNetStream is a sniffer and a protocol analyzer. 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.SlyCopyOr shorthand for SlyDecoder using the default main class:-> java -jar JNetStream.jarNote: /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.
