-OnionPerf has a couple dependencies in order to perform measurements or analyze and visualize measurement results. These dependencies include Tor, TGen (traffic generator), and a couple Python packages. +OnionPerf has several dependencies in order to perform measurements or analyze and visualize measurement results. These dependencies include Tor, TGen (traffic generator), and a few Python packages.

The following description was written with a Debian system in mind but should be transferable to other Linux distributions and possibly even other operating systems.

In that case, OnionPerf runs without needing any additional configuration. For direct measurements via exit nodes, firewall rules or port forwarding may be required to allow inbound connections to the TGen server.
