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.

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.

Para conectarse a la red Tor:

1. Conéctate a una red local, cableada, Wi-Fi, o móvil.

2. El asistente Tor Connection aparece para ayudarte a conectarte a la red Tor.

   

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.

Repetidores Tor y puentes

• Repetidores Tor públicos

  La mayoría de las veces, tu red local no bloquea el acceso a la red Tor y puedes usar un repetidor público como tu primer repetidor Tor.

  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.

  Los puentes Tor suelen ser menos fiables y más lentos que los repetidores Tor públicos..

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:

1. First, Tails synchronizes the clock of the computer automatically, because a correct time is needed to be able to connect to the Tor network.

   Tails learns the current time by connecting to the captive portal detection service of Fedora, which is used by most Linux distributions. This connection does not go through the Tor network and is an exception to our policy of only making Internet connections through the Tor network.

   You can learn more about our security assessment of this time synchronization in our design documentation about non-Tor traffic.

   If you choose instead to hide that you are connecting to Tor, you might have to fix the computer clock manually.

2. If Tails fails to synchronize the clock because you have to sign in to the network using a captive portal, an error screen is displayed that helps you do so.

   For detailed instructions, see how to sign in to the network using a captive portal.

3. Then, Tails tries different ways of connecting to Tor until it succeeds:

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

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

      Tails uses the default obfs4 bridges from Tor Browser.

   3. If public relays and default bridges don't work, 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.

Ocultar a la red local que estás usando 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.

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

• Tails does not automatically detect whether you have to sign in to the network using a captive portal.

• Default bridges are not available.

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

  To request a custom bridge, you can either:

  1. Request a bridge 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.

     For example, you can send the email from your phone and type the bridge in Tails.

     Sending the email reveals to Gmail or Riseup that you are trying to connect to Tor but not to someone who monitors your Internet connection.

     Even someone who knows your bridge cannot know what you are doing online from Tails.

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

Viewing the status of Tor

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