<h1>Configuring a Tor relay</h1>

<hr>

<p>
    The Tor network relies on volunteers to donate bandwidth. The more
    people who run relays, the faster the Tor network will be. If you have
    at least 50 kilobytes/s each way, please help out Tor by configuring your
    Tor to be a relay too.
    </p>

<p>You can run a Tor relay on pretty much any operating system. Tor relays
    work best on Linux, OS X Tiger or later, FreeBSD 5.x+, NetBSD 5.x+, and
    Windows Server 2003 or later.
    </p>

<p>If you're comfortable editing text files, skip this page and
    go to our dedicated <a href="<page docs/tor-relay-debian>">Relay
    Configuration Instructions on Debian/Ubuntu</a> page. That page is
    the best one for relay operators on BSD, Unix, etc as well.</p>

    <h2><a class="anchor" href="#install">Step One: Download and Install Tor</a></h2>
    <br>

<p>Before you start, you need to make sure that Tor is up and running.
    </p>

<p>Visit our <a href="<page download/download>">download page</a> and
    install the "Installation Bundle" for your OS.
    </p>

<p>If it's convenient, you might also want to use it as a client for a
    while to make sure it's actually working.</p>

    <h2><a class="anchor" href="#setup">Step Two: Set it up as a relay</a></h2>
    <br>
    <ol>

<li>Verify that your clock and timezone are set
    correctly. If possible, synchronize your clock with public <a
    href="http://en.wikipedia.org/wiki/Network_Time_Protocol">time
    servers</a>.
    </li>

<li><strong>Configuring Tor with the Vidalia Graphical Interface</strong>:
    <ol>

<li>
    	<dt>Right click on the Vidalia icon in your task bar.  Choose <tt>Control Panel</tt>.</dt>
    	<dd><img alt="vidalia right click menu" src="$(IMGROOT)/screenshot-win32-vidalia.png" /></dd>
    </li>

<li>Click <tt>Setup Relaying</tt>.</li>

<li>
    	<dt>Choose <tt>Relay Traffic for the Tor network</tt> if you
want to be a public relay (recommended), or choose <tt>Help
censored users reach the Tor network</tt> if you want to be a <a
href="<page docs/faq>#RelayOrBridge">bridge</a> for users in countries
that censor their Internet.</dt>
    <dd><img alt="vidalia basic settings" src="$(IMGROOT)/screenshot-win32-configure-relay-1.png" /></dd>
    </li>

<li>Enter a nickname for your relay, and enter contact information in
    case we need to contact you about problems.</li>

<li>Leave <tt>Attempt to automatically configure port forwarding</tt> clicked.
    Push the <tt>Test</tt> button to see if it works.  If it does work, great.
    If not, see number 3 below.</li>

<li><dt>Choose the <tt>Bandwidth Limits</tt> tab.  Select how much bandwidth you want to provide for Tor users like yourself.</dt>
    <dd><img alt="vidalia bandwidth limits" src="$(IMGROOT)/screenshot-win32-configure-relay-2.png" /></dd>
    </li>

<li><dt>Choose the <tt>Exit Policies</tt> tab.  If you want to allow others
    to use your relay for these services, don't change anything.  Un-check
    the services you don't want to allow people to <a href="<page
    docs/faq>#ExitPolicies">reach from your relay</a>.  If you want to
    be a non-exit relay, un-check all services.</dt>
    <dd><img alt="vidalia exit policies" src="$(IMGROOT)/screenshot-win32-configure-relay-3.png" /></dd>
    </li>

<li>Click the <tt>Ok</tt> button.  See Step Three below for confirmation
    that the relay is working correctly.</li>
    </ol>

<li>If you are using a firewall, open a hole in your firewall
    so incoming connections can reach the ports you configured
    (ORPort, plus DirPort if you enabled it). If you have a
    hardware firewall (Linksys box, cablemodem, etc) you might like <a
    href="http://portforward.com/">portforward.com</a>. Also, make sure you
    allow all <em>outgoing</em> connections too, so your relay can reach the
    other Tor relays.
    </li>

<li>Restart your relay. If it <a
    href="<page docs/faq>#Logs">logs
    any warnings</a>, address them.
    </li>

<li>Subscribe to the <a
    href="https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-announce">tor-announce</a>
    mailing list. It is very low volume, and it will keep you informed
    of new stable releases. You might also consider subscribing to <a
    href="<page docs/documentation>#MailingLists">the higher-volume Tor lists</a>
    too.</li>
    <li><a href="https://weather.torproject.org/">Tor Weather</a> provides
    an email notification service to any users who want to monitor the
    status of a Tor node. Upon subscribing, you can specify what types of
    alerts you would like to receive. The main purpose of Tor Weather is
    to notify node operators via email if their node is down for longer
    than a specified period, but other notification types are available.
    </li>

    <h2><a class="anchor" href="#check">Step Three: Make sure it is working</a></h2>
    <br>

<p>As soon as your relay manages to connect to the network, it will
    try to determine whether the ports you configured are reachable from
    the outside. This step is usually fast, but may take up to 20
    minutes. Look for a <a href="<page docs/faq>#Logs">log entry</a> like
    <tt>Self-testing indicates your ORPort is reachable from the outside. Excellent.</tt>
    If you don't see this message, it means that your relay is not reachable
    from the outside &mdash; you should re-check your firewalls, check that it's
    testing the IP and port you think it should be testing, etc.
    </p>

<p>When it decides that it's reachable, it will upload a "server
    descriptor" to the directories, to let clients know
    what address, ports, keys, etc your relay is using. You can <a
    href="http://194.109.206.212/tor/status-vote/current/consensus">load one of
    the network statuses manually</a> and
    look through it to find the nickname you configured, to make sure it's
    there. You may need to wait up to one hour to give enough time for it to
    make a fresh directory.</p>

<hr>
    <a id="after"></a>
    <h2><a class="anchor" href="#after">Step Four: Once it is working</a></h2>
    <br>

<p>Read
    <a href="<wiki>doc/OperationalSecurity">about operational security</a>
    to get ideas how you can increase the security of your relay.
    </p>

<p>
    If you control the name servers for your domain, consider setting your
    reverse DNS hostname to 'anonymous-relay', 'proxy' or 'tor-proxy', so when
    other people see the address in their web logs, they will more quickly
    understand what's going on. Adding the <a
    href="<gitblob>contrib/tor-exit-notice.html">Tor
    exit notice</a> on a vhost for this name can go a long way to deterring abuse
    complaints to you and your ISP if you are running an exit node.
    </p>

<p>
    When you change your Tor configuration, remember to verify that your
    relay still works correctly after the change.
