<h2><a name="topology"></a>Topology</h2>
<p>Nodes with <code>tor</code> service will run a Tor relay with some pre-defined settings, which can be changed with some configuration (see <em>Configuration</em> below). You can enable an exit or a hidden service with additional configuration.</p>
<h2><a name="configuration"></a>Configuration</h2>
<p>By default, if a node has service ‘tor’ configured, it will run a tor relay (not an exit). The relay will be configured with bandwidth limitations, contacts, a nickname and a family. The defaults for these (shown below), can be overridden as desired.</p>
<ul>
<li><code>tor.bandwidth_rate</code>: the max bandwidth allocated to Tor, in KB per second, when used as an exit node (default: 6550 KB/sec).</li>
<li><code>tor.type</code>: what type of tor node to make, at this moment only ‘exit’ is supported. If not specified, acts as a relay.</li>
<li><code>tor.contacts</code>: the contact information for the relay (default: the list of provider contacts)</li>
<li><code>tor.nickname</code>: the nickname of the relay (default: a combination of the node name and a hash of the family)</li>
<li><code>tor.family</code>: a list of the other nicknames that are part of the same provider</li>
<li><code>tor.hidden_service</code>: to enable a hidden service, set ‘active’ to be true (see below for an example), do <em>not</em> configure “services”: [“tor”] for the node!</li>
</ul>
<p>Examples:</p>
<p>To add a relay to a node:</p>
<pre><code>{
"services": ["tor"]
}
</code></pre>
<p>To enable a hidden service, without a relay, do <em>not</em> specify the tor service (it is not considered secure to have a node configured as a relay and a hidden service at the same time, see: <a href="https://trac.torproject.org/8742">https://trac.torproject.org/8742</a>), instead configure the node to have the following:</p>
<pre><code>{
"tor": {
"hidden_service": {
"active": true
}
}
</code></pre>
<p>If activated, you can list the hidden service .onion addresses this way:</p>
<p> leap ls –print tor.hidden_service.address tor</p>
<p>Then just add ‘.onion’ to the end of the printed addresses.</p>
<p>To enable a Tor exit node:</p>
<pre><code>{
"tor": {
"bandwidth_rate": 6550,
"type": "exit"
}
}
</code></pre>
