#SETUP TOR PROXY LINUX INSTALL#

Once the iptables configuration is complete, the script waits for a keypressing for starting deactivation process: a simple flush of iptables rules and a restore of previous configuration, and a brief cleanup of support files.

This rules are configured for all system users except for root user (that starts the script and conseguently the tor process). The next step is the configuration of firewalls rules, that first forward all dns request to the DNS relay port, then route all traffic throught the transparent proxy port opened by tor. Just be careful to pay attention to network throughput. You could easily use a Raspberry Pi 3 or similar type device as long as it supports Linux. For this build, I chose to go with a Raspberry Pi 4. Then kills other tor processes and start a brand-new session with custom torrc. Step 1: Assemble Your Hardware To get started, we need to gather a few parts. That enable a transparent proxy port and a DNS relay on TOR. The purpose of this 'exercise' is to create a script that allows semi-automatically to configure the system to route all output connections made by the current user through TOR.īased on this tutorial, the script (that need to be started as root: also this not a best practice!) creates a custom torrc file with this options: So, consider this script as a simple exercise, not privacy-focused. Most default setting should be sufficient.

Operating system updates, emails, web browsing, and fetching information about media you play will all share the same circuit, so the exit node could connect all of these things together and link them to a single entity: things intended to be anonymous could be linked to things which reveal your identity or used as a fingerprint that an observer watching Exit traffic could piece together. If Tor is not installed you can install it on Debian based Linux systems (Ubuntu, Debian, etc) with the following command: sudo apt install tor then /etc/init.d/tor start or sudo systemctl enable -now tor depending on your system configuration. When you take your whole operating system and stick it behind transparent proxying, everything goes over Tor using, by default, the same circuit.

Please note: this is not a best practice. Using operating system's packet filtering system is possible to redirect all outbound connections into a transparent proxy. Tor has support for transparent proxy connections in addition to SOCKS connections. Yes, It's possible, using a specific feature of Tor. The starting idea comes from a colleague that asked me: 'Is it possibile routing all system traffic thougth TOR, using it as a sort of VPN?'. The installation sequence described above was tested on the current Ubuntu, Fedora, and Manjaro Linux distributions.
