English Actions
[[!meta title="Managing the circuits of Tor"]]
<span class="application">Onion Circuits</span> displays information about
the current Tor circuits and connections.
To open **Onion Circuits**, click on the
Tor status icon ([[!img lib/symbolic/tor-disconnected.png alt="Tor status menu" link="no" class="symbolic"]]
or [[!img lib/symbolic/tor-connected.png alt="Tor status menu" link="no"
class="symbolic"]]) in the top-right corner and choose **View Tor Circuits**.
<h1 id="view">Understanding Tor circuits</h1>
If Tails is already [[connected to the Tor network|doc/anonymous_internet/tor]], a list of Tor circuits appears in the left pane of *Onion Circuits*.
<!-- Note for translators: the entry guards in use when you take the screenshot
onion-circuits.png is in a position to identify you. You might prefer to leave it
untranslated. -->
When you connect to a destination server, for example, when visiting a website, the connection appears in the list below the circuit it uses.
Click on a circuit to display the technical details about each relay in the right pane.
[[!img onion-circuits.png link=no]]
Each Tor circuit is made of 3 Tor relays. In the example above, the connection to **tails.net** goes through the 3 relays **drk**, **kicka**, and **Quetzalcoatl**.
The first relay, here **drk**, is called the *entry guard*.
If you use a Tor bridge:
Tor uses the bridge as your entry guard.
If you don't use a Tor bridge:
Tor uses only 2 different relays as your entry guards, as a way of [protecting against *end-to-end correlation* attacks](https://support.torproject.org/about/entry-guards/).
Your entry guards change every time you restart Tails.
To keep the same entry guard across different Tails sessions, use a
Tor bridge instead.
The second relay, here **kicka**, is called the *middle relay*.
The third relay, here **Quetzalcoatl**, is called the *exit node*.
[[!img doc/anonymous_internet/tor/tor.png link="no" alt="Schematics of a connection to Tor with the client, the 3 relays, and the destination server."]]
<h1 id="change">Closing and replacing a Tor circuit</h1>
You can close a given Tor circuit to help replace a particularly slow Tor circuit or troubleshoot issues on the Tor network. To do so:
Right-click (on Mac, click with two fingers) on the circuit that you want to close.
Choose **Close this circuit** in the shortcut menu.
When you close a circuit that is being used by an application, your
application gets disconnected from this destination service.
For example, when you close a circuit while <i>Tor Browser</i> is
downloading a file, the download fails.
If you connect to the same destination server again, Tor uses a different circuit to replace the circuit that you closed.
For example, if you download the same file again, Tor uses a new circuit.
