|
||
<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>
|
||
<section id="auto-interface">
|
||
<span id="interfaces-auto"></span><h2>Auto Interface<a class="headerlink" href="#auto-interface" title="Permalink to this heading">#</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>
|

<p>If you are connected to the Internet with IPv6, and your provider will route

IPv6 multicast, you can potentially configure the Auto Interface to globally

the discovery scope by setting it to one of <code class="docutils literal notranslate"><span class="pre">link</span></code>, <code class="docutils literal notranslate"><span class="pre">admin</span></code>, <code class="docutils literal notranslate"><span class="pre">site</span></code>,

<section id="i2p-interface">

||
<span id="interfaces-i2p"></span><h2>I2P Interface<a class="headerlink" href="#i2p-interface" title="Permalink to this heading">#</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.</p>
|
||
<p>To use the I2P interface, you must have an I2P router running
|
||
on your system. The easiest way to achieve this is to download and
|
||
install the <a class="reference external" href="https://github.com/PurpleI2P/i2pd/releases/latest">latest release</a>
|
||
of the <code class="docutils literal notranslate"><span class="pre">i2pd</span></code> 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>
|
||
<span class="n">connectable</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
|
||

<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>To connect to a TCP server interface, you would naturally use the TCP client

|

<p>The TCP interface types can also tolerate intermittency in the IP link layer.

This means that Reticulum will gracefully handle IP links that go up and down,

|

<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>

<p>The built-in announce control mechanisms and the default <code class="docutils literal notranslate"><span class="pre">announce_cap</span></code>
|
||
option described above are sufficient most of the time, but in some cases, especially on fast
|
||
interfaces, it may be useful to control the target announce rate. Using the

||
<code class="docutils literal notranslate"><span class="pre">announce_rate_target</span></code>, <code class="docutils literal notranslate"><span class="pre">announce_rate_grace</span></code> and <code class="docutils literal notranslate"><span class="pre">announce_rate_penalty</span></code>
|
||
options, this can be done on a per-interface basis, and moderates the <em>rate at

<div class="line">The <code class="docutils literal notranslate"><span class="pre">announce_rate_target</span></code> option sets the minimum amount of time,

in seconds, that should pass between received announces, for any one

|
||
<p>These mechanisms, in conjunction with the <code class="docutils literal notranslate"><span class="pre">annouce_cap</span></code> mechanisms mentioned
|
||
above means that it is essential to select a balanced announce strategy for
|
||
your destinations. The more balanced you can make this decision, the easier
|
||
it will be for your destinations to make it into slower networks that many hops
|
||
away. Or you can prioritise only reaching high-capacity networks with more frequent
|
||
announces.</p>
|
||
<p>Current statistics and information about announce rates can be viewed using the
|
||
<code class="docutils literal notranslate"><span class="pre">rnpath</span> <span class="pre">-r</span></code> command.</p>
|
||
<p>It is important to note that there is no one right or wrong way to set up announce
|
||
rates. Slower networks will naturally tend towards using less frequent announces to
|
||
conserve bandwidth, while very fast networks can support applications that
|
||
need very frequent announces. Reticulum implements these mechanisms to ensure
|
||
that a large span of network types can seamlessly <em>co-exist</em> and interconnect.</p>
