|
||
<p>Reticulum supports using many kinds of devices as networking interfaces, and
|
||
allows you to mix and match them in any way you choose. The number of distinct
|
||
network topologies you can create with Reticulum is more or less endless, but
|
||
common to them all is that you will need to define one or more <em>interfaces</em>
|
||
for Reticulum to use.</p>
|
||
<p>The following sections describe the interfaces currently available in Reticulum,
|
||
and gives example configurations for the respective interface types.</p>
|
||
<p>For a high-level overview of how networks can be formed over different interface
|
||
types, have a look at the <a class="reference internal" href="networks.html#networks-main"><span class="std std-ref">Building Networks</span></a> chapter of this
|
||
manual.</p>

<div class="section" id="auto-interface">
|
||
<span id="interfaces-auto"></span><h2>Auto Interface<a class="headerlink" href="#auto-interface" title="Permalink to this headline">¶</a></h2>
|
||
<p>The Auto Interface enables communication with other discoverable Reticulum
|
||
nodes over autoconfigured IPv6 and UDP. It does not need any functional IP
|
||
infrastructure like routers or DHCP servers, but will require at least some
|
||
sort of switching medium between peers (a wired switch, a hub, a WiFi access
|
||
point or similar), and that link-local IPv6 is enabled in your operating
|
||
system, which should be enabled by default in almost all OSes.</p>

<span id="interfaces-i2p"></span><h2>I2P Interface<a class="headerlink" href="#i2p-interface" title="Permalink to this headline">¶</a></h2>
|
||
<p>The I2P interface lets you connect Reticulum instances over the
|
||
<a class="reference external" href="https://i2pd.website">Invisible Internet Protocol</a>. This can be
|
||
especially useful in cases where you want to host a globally reachable
|
||
Reticulum instance, but do not have access to any public IP addresses,
|
||
have a frequently changing IP address, or have firewalls blocking
|
||
inbound traffic.</p>
|
||
<p>Using the I2P interface, you will get a globally reachable, portable
|
||
and persistent I2P address that your Reticulum instance can be reached
|
||
at. The I2P</p>
|
||
<p>To use the I2P interface, you must have an I2P router running
|
||
on your system. The easiest way to acheive this is to download and
|
||
install the <a class="reference external" href="https://github.com/PurpleI2P/i2pd/releases/latest">latest release</a>
|
||
of the <a href="#id1"><span class="problematic" id="id2">``</span></a>ì2pd```package. For more details about I2P, see the
|
||
<a class="reference external" href="https://geti2p.net/en/about/intro">geti2p.net website</a>.`</p>
|
||
<p>When an I2P router is running on your system, you can simply add
|
||
an I2P interface to reticulum:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="p">[[</span><span class="n">I2P</span><span class="p">]]</span>
|
||
<span class="nb">type</span> <span class="o">=</span> <span class="n">I2PInterface</span>
|
||
<span class="n">interface_enabled</span> <span class="o">=</span> <span class="n">yes</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>On the first start, Reticulum will generate a new I2P address for the
|
||
interface and start listening for inbound traffic on it. This can take
|
||
a while the first time, especially if your I2P router was also just
|
||
started, and is not yet well-connected to the I2P network. When ready,
|
||
you should see I2P base32 address printed to your log file. You can
|
||
also inspect the status of the interface using the <code class="docutils literal notranslate"><span class="pre">rnstatus</span></code> utility.</p>
|
||
<p>To connect to other Reticulum instances over I2P, just add a comma-separated
|
||
list of I2P base32 addresses to the <a href="#id3"><span class="problematic" id="id4">``</span></a>peers```option of the interface:</p>
|
||
<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="p">[[</span><span class="n">I2P</span><span class="p">]]</span>
|
||
<span class="nb">type</span> <span class="o">=</span> <span class="n">I2PInterface</span>

||
<span class="n">interface_enabled</span> <span class="o">=</span> <span class="n">yes</span>

|
||
</pre></div>
|
||
</div>
|
||
<p>It can take anywhere from a few seconds to a few minutes to establish
|
||
I2P connections to the desired peers, so Reticulum handles the process
|
||
in the background, and will output relevant events to the log.</p>
|
||
<p><strong>Please Note!</strong> While the I2P interface is the simplest way to use
|
||
Reticulum over I2P, it is also possible to tunnel the TCP server and
|
||
client interfaces over I2P manually. This can be useful in situations
|
||
where more control is needed, but requires manual tunnel setup through
|
||
the I2P daemon configuration.</p>
|
||
<p>It is important to note that the two methods are <em>interchangably compatible</em>.
|
||
You can use the I2PInterface to connect to a TCPServerInterface that
|
||
was manually tunneled over I2P, for example. This offers a high degree
|
||
of flexibility in network setup, while retaining ease of use in simpler
|
||
use-cases.</p>

|
||
<p>If you’re using Reticulum on amateur radio spectrum, you might want to
|
||
use the AX.25 KISS interface. This way, Reticulum will automatically
|
||
encapsulate it’s traffic in AX.25 and also identify your stations
|
||
transmissions with your callsign and SSID.</p>
|
||
<p>Only do this if you really need to! Reticulum doesn’t need the AX.25
|
||
layer for anything, and it incurs extra overhead on every packet to
|
||
encapsulate in AX.25.</p>
|
||
<p>A more efficient way is to use the plain KISS interface with the

||
beaconing functionality described above.</p>

<span id="interfaces-options"></span><h2>Common Interface Options<a class="headerlink" href="#common-interface-options" title="Permalink to this headline">¶</a></h2>
|
||
<p>A number of general options can be used to control various
|
||
aspects of interface behaviour.</p>
|
||
<p>The <code class="docutils literal notranslate"><span class="pre">outgoing</span></code> option sets whether an interface is allowed
|
||
to transmit. Defaults to <code class="docutils literal notranslate"><span class="pre">True</span></code>. If set to <code class="docutils literal notranslate"><span class="pre">False</span></code> the
|
||
interface will only receive data, and never transmit.</p>
|
||
<p>The <code class="docutils literal notranslate"><span class="pre">interface_mode</span></code> option allows selecting the high-level
|
||
behaviour of the interface from a number of options.</p>
|
||
<blockquote>
|
||
<div><ul class="simple">
|
||
<li><p>The default value is <code class="docutils literal notranslate"><span class="pre">full</span></code>. In this mode, all discovery,
|
||
meshing and transpor functionality is available.</p></li>
|
||
<li><p>In the <code class="docutils literal notranslate"><span class="pre">access_point</span></code> (or shorthand <code class="docutils literal notranslate"><span class="pre">ap</span></code>) mode, the
|
||
interface will operate as a network access point. In this
|
||
mode, announces will not be automatically broadcasted on
|
||
the interface, and paths to destinations on the interface
|
||
will have a much shorter expiry time. This mode is useful
|
||
for creating interfaces that are mostly quiet, unless when
|
||
someone is actually using them. An example of this could
|
||
be a radio interface serving a wide area, where users are
|
||
expected to connect momentarily, use the network, and then
|
||
disappear again.</p></li>
|
||
</ul>
|
||
</div></blockquote>
|
||
<p>The <code class="docutils literal notranslate"><span class="pre">interface_enabled</span></code> option tells Reticulum whether or not
|
||
to bring up the interface. Defaults to <code class="docutils literal notranslate"><span class="pre">False</span></code>. For any
|
||
interface to be brought up, the <code class="docutils literal notranslate"><span class="pre">interface_enabled</span></code> option
|
||
must be set to <code class="docutils literal notranslate"><span class="pre">True</span></code> or <code class="docutils literal notranslate"><span class="pre">Yes</span></code>.</p>
