Scraper

A full event-loop based scraper following a publish-subscribe model. Backed by Redis, so you need it (!) Requires a recent Python 3 installation. Install dependencies with pip3 install -r requirements.txt.

You can define your queues in config.json. You can reload the scraper without killing it with kill -s SIGHUP <pid> or systemctl reload service.

TorFone has been developped for Windows. However it appears that it works pretty well with Wine on Linux.

This guide is targetting Fedora 29, but most of the instructions will be the same with other Linux distributions and even on Windows, it will be mostly the same steps.

You must start by installing required dependencies:

sudo dnf install wget wine tor unzip

superboum

const fs = require('fs')
const content = fs.readFileSync('single-host_latency.json').toString('utf-8').split("\n")
content.pop()
const parsed = content.map(JSON.parse)

console.log("Number of RTT measured for Tor Circuit 0:", parsed[0][10].length)
console.log("Number of Tor Circuit created:", parsed.length)

const broken_from_beginning = parsed.filter(l => l[10].length == 0).length
const broken_en_route = parsed.filter(l => l[10].length > 0 && l[10].length < 600).length
