How do you set up a Tor bridge relay?

If you're starting Tor Browser for the first time, click "Tor Network Settings" to open the Tor settings window. Under the "Bridges" section, select the checkbox "Use a bridge", choose "Provide a bridge I know" and enter each bridge address on a separate line. Click "Connect" to save your settings.

Can I run a Tor relay?

While the EFF believes running a Tor "exit node is legal," its Tor Challenge stated, "Exit relays raise special concerns because the traffic that exits from them can be traced back to the relay's IP address." Furthermore, the EFF does not recommend running an exit relay from your home, since it's realistic that someone ...

What is a Tor relay?

Tor relays are also referred to as "routers" or "nodes." They receive traffic on the Tor network and pass it along. Check out the Tor website for a more detailed explanation of how Tor works. There are three kinds of relays that you can run in order to help the Tor network: middle relays, exit relays, and bridges.

Why should I run a Tor relay?

By running a Tor relay you can help make the Tor network: faster (and therefore more usable) more robust against attacks. more stable in case of outages.

How is a Tor circuit created?

A Tor circuit is made up of a guard node, a middle node, and an exit node. The client starts the circuit formation process by contacting the node it has chosen as its guard node. The client and guard node negotiate a TLS session, and the client asks the guard node to help it initialize a Tor circuit.

How does a Tor circuit work?

Tor works by sending your traffic through three random servers (also known as relays) in the Tor network. The last relay in the circuit (the “exit relay”) then sends the traffic out onto the public Internet. The image above illustrates a user browsing to different websites over Tor.

How much bandwidth does a Tor relay use?

It is recommended that a relay have at least 16 Mbit/s (Mbps) upload bandwidth and 16 Mbit/s (Mbps) download bandwidth available for Tor. More is better. The minimum requirements for a relay are 10 Mbit/s (Mbps). If you have less than 10 Mbit/s but at least 1 Mbit/s we recommend you run a bridge with obfs4 support.

How much RAM does Tor use?

All of this said, fast Tor relays do use a lot of ram. It is not unusual for a fast exit relay to use 500-1000 MB of memory.

How many relays are in a Tor circuit?

A Tor circuit is made of three relays: The first relay or entry guard. If you configured Tor bridges, one of your bridges is the first relay. The second relay or middle node.

Who maintains Tor relays?

Tor (aka The Onion Router) is software that allows users to browse the web anonymously by encrypting and routing requests through multiple relay layers or nodes. This software is maintained by the Tor Project, a nonprofit organization that provides internet anonymity and anti-censorship tools.

Does Tor use UDP or TCP?

Tor only supports TCP. Non-TCP traffic to the Internet, such as UDP datagrams and ICMP packets, is dropped.

Why does Tor use 3 relays?

Tor uses only three relays by default because that's the bare minimum you need for safety. You can always use more…at a price. One would be pointless, since whoever operates that node you chose will see everything. Two is dangerous, because the entry and exit nodes would then be directly connected.

How to set up Torrc?

The torrc is in the Tor Browser Data directory at ~/Library/Application Support/TorBrowser-Data/Tor . Note the Library folder is hidden on newer versions of macOS. To navigate to this folder in Finder, select "Go to Folder..." in the "Go" menu. Then type ~/Library/Application Support/ in the window and click Go.

How do Tor bridges work?

Bridges are private Tor relays that serve as stepping stones into the network. When the Tor network is blocked, users can get a bridge to circumvent censorship.

How does Tor choose relays?

Tor chooses an exit relay which actually allows you to exit the Tor network. Some only allow web traffic (port 80) which is not useful when someone wants to send emails. The exit relay has to have available capacities. Tor tries to choose such exits which have enough ressources available.

What ports need to be open for Tor?

Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) ports commonly affiliated with Tor include 9001, 9030, 9040, 9050, 9051, and 9150.

How do you show a Tor circuit?

You can view your current Tor circuit by clicking on the [i] on the URL bar.

Where is the config of Tor?

Installation. First of all, install the tor plugin (os-tor) from the plugins view. After a page reload you will get a new menu entry under services for Tor. Open the menu and choose “Configuration” to configure the plugin.
