Stem: is a Python controller library for TOR.TOR: Is an abbreviation of 'The Onion Project', a project that seeks to create a low latency distributed communication network above the Internet layer so that the data of the users who use it will be never reveal, thus maintaining a private and anonymous network.To develop agents that perform scraping anonymously on a proxy server, it is necessary install a Linux distribution (with Ubuntu packages) with following tools:

On the other hand this server will run under a Linux distribution based on Ubuntu packages (in this tutorial a Linux Mint 18.1 has been used). In this tutorial we will explain how to configure a proxy server for scraping websites anonymously through the TOR network, using TOR ( ), Privoxy ( ) and the python-Stem library ( ).
