evand/pyProbe

A Python implementation of Freenet topology probing and analysis using TMCI.

pyProbe

pyProbe is a collection of data gathering and analysis tools for Freenet network probes.

Requirements

• Python 2.6.6-ish
• pysqlite
• Freenet
• gnuplot
• libGEXF (Optional - only for exporting network topology.)

Setup

Installing pysqlite

• Download and extract the source tarball.
• sudo python setup.py install

Enabling TMCI

• Shut down Freenet. Freenet will write out its settings on shutdown so these changes cannot be made while the node is running.
• In freenet.ini, set these options, or add them if they do not exist:
  • console.enabled=true
  • console.directEnabled=true
• Start Freenet again.

Installing libGEXF

• Download and extract the source tarball. (Word of warning: as of this writing the archive contains no top-level directory.)
• Install swig.
• ./autogen.sh
• ./configure
• make
• cd binding/python
• sudo python setup.py install

Usage

The three tools are:

• probe.py: connects to a Freenet node and makes probe requests to random locations, storing the results in a database.
• analyze.py: reads probe results from a database, generating plots of the data and optionally a network topology graph.
• util.py: provides statistics on the amount of information held by the database and allows easily running the sqlite commands analyze and vacuum.

Help screens are available by running a tool with the --help or -h arguments.
