JGroupsAnalyser

by Francois Billard <francois@alyseo.com>

JGroupsAnalyser allow you to get and display JGroups disassembled packets 

Features

  • Scan network interface for JGroups packets like wireshark (with IP defragmentation)
  • Load and decode pcap file
  • Display payload message (binary to string, uncompress)
  • Load externals jars to unserialize object found in the payload and display .toString() method
  • Save decoded content as CSV file

Prerequisites

  • Java jre 1.5+
  • pcap library, version 0.9 if possible, it works with v0.8 and v0.9 symbolic link
  • libjnetpcap.so version 1.3, available on http://jnetpcap.com/download

Usage

Just launch binary (in target directory) :

  • on Linux : /linux.gtk.x86/JGroupsAnalyser/JgroupsAnalyser
  • on Windows (a setup is coming soon): /win32.win32.x86/JGroupsAnalyser\JGroupsAnalyser

Compatibility

  • JGroups 2.10
  • JGroups 2.11
  • JGroups 2.12

JGroupsAnalyser will work with all next JGroups versions as long as the parse class will be present in the JGroups distrib. (Thank you Bela to keep it :)

TODO

  • JGroups FRAG2 protocol defragmentation
  • filter and sorting on column (workaround today: export to CSV and sort/filter with programm like Excel)
  • find why Linux version is slower than Windows version (a pcap load is five time faster)
Something went wrong with that request. Please try again.
