Todo lo que haces en Internet desde Tails pasa por la red Tor.

Tor cifra y anonimiza tu conexión pasándola a través de 3 repetidores. Los repetidores de Tor son servidores operados por diferentes personas y organizaciones en todo el mundo.

A Tor connection goes through 3 relays with the last one establishing the actual connection to the final destination

You cannot access the Internet from Tails until you are connected to Tor. For example, Tor Browser displays the error message Proxy server refusing connections until you are connected to Tor.

Because Tor routes your Internet traffic through 3 relays before reaching its destination, the connection is slower than when you are not using Tor.

See our documentation on why Tor is slow.

Para conectarse a la red Tor:

  1. Connect to a local network, wired, Wi-Fi, or mobile.

  2. The Tor Connection assistant appears to help you connect to the Tor network.

  3. Elige si deseas:

    • Conectar a Tor automáticamente

    • Ocultar a la red local que estás usando Tor

    Las implicaciones de ambos métodos se detallan a continuación.

Tor relays and bridges

  • Public Tor relays

    Most of the time, your local network does not block access to the Tor network and you can use a public relay as your first Tor relay.

    Using a public Tor relay as your first Tor relay makes it clear to your local network that you are connecting to Tor, while still keeping your online activity secure and anonymous.

  • Puentes Tor

    Tor bridges are secret Tor relays that keep your connection to the Tor network hidden.

    Use a bridge as your first Tor relay if connecting to Tor is blocked or if using Tor could look suspicious to someone who monitors your Internet connection.

    The technology used by Tor bridges is designed to circumvent censorship where connections to Tor are blocked, for example in some countries with heavy censorship, by some public networks, or by some parental controls.

    It does so by camouflaging your connection so it cannot be recognized as a connection to Tor. As a consequence, the same technology can be used to hide that you are using Tor if it could look suspicious to someone who monitors your Internet connection.

    Tor bridges are often less reliable and slower than public Tor relays.

Conectarse a Tor automáticamente

Recomendamos conectarse a Tor automáticamente si está en una red Wi-Fi pública o si muchas personas en su país usan Tor para eludir la censura.

Cuando eliges esta opción, Tails intenta diferentes formas de conectarse a Tor hasta que tiene éxito:

  1. Tails tries to connect to Tor directly using public relays, without using bridges.

  2. Tails tries to connect to Tor using one of the default bridges, already included in Tails, if connecting using public relays fails.

  3. Tails asks you to configure a custom bridge, if connecting using the default bridges fails.

Alguien que esté monitoreando tu conexión a Internet podría identificar estos intentos como provenientes de un usuario de Tails.

In the future, Tails will also automatically:

  • Detect if you have to sign in to the local network using a captive portal (#5785)

Hiding to your local network that you are connecting to Tor

You might need to go unnoticed if using Tor could look suspicious to someone who monitors your Internet connection.

When you choose this option, Tails will only connect to Tor after you configure a Tor bridge. Bridges are secret Tor relays that hide that you are connecting to Tor.

It is impossible to hide to the websites that you visit that you are using Tor, because the list of exit nodes of the Tor network is public.

Our team is doing its best to help you connect to Tor using the most discrete types of Tor bridges. That is why, when you decide to hide that you are connecting to Tor:

  • Default bridges are not available.

    You will have to know the address of a custom bridge.

    To request custom bridges, you can either:

    1. Request bridges on https://bridges.torproject.org/.

      We recommend doing so before starting Tails and ideally from a different local network than the one on which you want to hide that you are using Tor.

    2. Send an empty email to bridges@torproject.org from a Gmail or Riseup email address.

      Sending such an email, from your phone for example, does not reveal to your local network that you are trying to connect to Tor.

  • You can only use the types of bridges that our team considers discrete enough.

    Currently in Tails, only obfs4 bridges hide that you are using Tor.

To save the last Tor bridge that connected to Tor successfully, turn on the Tor Bridge feature of the Persistent Storage.

In the future, we will make it easier to use custom bridges by:

Viewing the status of Tor

The status of Tor appears as an onion icon in the notification area:

  • Onion icon You are connected to Tor.

  • Onion icon that is crossed
out You are not connected to Tor.
