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.
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
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
--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.
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
