BWScanner

https://travis-ci.org/TheTorProject/bwscanner.svg?branch=develop https://coveralls.io/repos/github/TheTorProject/bwscanner/badge.svg?branch=develop&reload=1

BWScanner is a tool for measuring the bandwidth of Tor relays. Its aim is to replace the existing Torflow system.

This project is still under active development and is not ready for active use or production deployment yet.

Installation

BWScanner is not yet compatible with Python 3 due to the `txsocksx ` dependency.

In Debian/Ubuntu systems, you can install Python 2 and other systems requirements running:

sudo apt install python2.7 python2.7-dev

The bandwidth scanner and its dependencies can be installed as follows:

git clone https://github.com/TheTorProject/bwscanner.git
cd bwscanner
python setup.py install

In case your system is using Python 3 by default, you need to run Python 2 explicitely, changing last line by:

python2.7 setup.py install

Running

After installation the bwscan tool should be available in your path. This tool has a number of subcommands for running scans and for aggregating the collected data for use by the bandwidth authorities.

Collecting bandwidth measurements

The --partitions option can be used to split the consensus into subsets of relays which can be scanned on different machines. The results can later be combined during the measurement aggregation step.

bwscan scan

Aggregating scan results

This command will aggregate the data for the latest five completed scans.

bwscan aggregate -n 5

The final aggregation script is not yet integrated with the CLI. It should be called with the path to the directory containing the most recent aggregated data:

python scripts/aggregate.py ~/.config/bwscanner/measurements/1474278776
