Nmap
</h1>
</header>
<hr class="divider">
<p>As an alternative to the router-based device tracking, it is possible to directly scan the network for devices by using Nmap. The IP addresses to scan can be specified in any format that Nmap understands, including the network-prefix notation (<code class="highlighter-rouge">192.168.1.1/24</code>) and the range notation (<code class="highlighter-rouge">192.168.1.1-255</code>).</p>
<p>If youre on Debian or Ubuntu, you might have to install the packages for <code class="highlighter-rouge">arp</code> and <code class="highlighter-rouge">nmap</code>. Do so by running <code class="highlighter-rouge">$ sudo apt-get install net-tools nmap</code>. On a Fedora host run <code class="highlighter-rouge">$ sudo dnf -y install nmap</code>.</p>
<p>Host detection is done via Nmaps “fast scan” (<code class="highlighter-rouge">-F</code>) of the most frequently used 100 ports, with a host timeout of 5 seconds.</p>
<p>To use this device tracker in your installation, add the following to your <code class="highlighter-rouge">configuration.yaml</code> file:</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry</span>
<span class="s">device_tracker</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">platform</span><span class="pi">:</span> <span class="s">nmap_tracker</span>
<span class="s">hosts</span><span class="pi">:</span> <span class="s">192.168.1.1/24</span>
</code></pre>
</div>
<p>Configuration variables:</p>
<ul>
<li><strong>hosts</strong> (<em>Required</em>): The network address to scan (in any supported NMap format). Mixing subnets and IPs is possible.</li>
<li><strong>home_interval</strong> (<em>Optional</em>): The number of minutes nmap will not scan this device, assuming it is home, in order to preserve the device battery.</li>
<li><strong>exclude</strong> (<em>Optional</em>): Hosts not to include in nmap scanning.</li>
<li><strong>scan_options</strong> (<em>Optional</em>): Configurable scan options for nmap. Default to <code class="highlighter-rouge">-F --host-timeout 5s</code></li>
</ul>
<p>A full example for the <code class="highlighter-rouge">nmap</code> tracker could look like the following sample:</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml entry for nmap</span>
<span class="c1"># One whole subnet, and skipping two specific IPs.</span>
<span class="s">device_tracker</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">platform</span><span class="pi">:</span> <span class="s">nmap_tracker</span>
<span class="s">hosts</span><span class="pi">:</span> <span class="s">192.168.1.1/24</span>
<span class="s">home_interval</span><span class="pi">:</span> <span class="s">10</span>
<span class="s">exclude</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">192.168.1.12</span>
<span class="pi">-</span> <span class="s">192.168.1.13</span>
</code></pre>
</div>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="c1"># Example configuration.yaml for nmap</span>
<span class="c1"># One subnet, and two specific IPs in another subnet.</span>
<span class="s">device_tracker</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">platform</span><span class="pi">:</span> <span class="s">nmap_tracker</span>
<span class="s">hosts</span><span class="pi">:</span>
<span class="pi">-</span> <span class="s">192.168.1.1/24</span>
<span class="pi">-</span> <span class="s">10.0.0.2</span>
<span class="pi">-</span> <span class="s">10.0.0.15</span>
</code></pre>
</div>
<p>In the above example, Nmap will be call with the process:
<code class="highlighter-rouge">nmap -oX - 192.168.1.1/24 10.0.0.2 10.0.0.15 -F --host-timeout 5s</code></p>
<p>An example of how the Nmap scanner can be customized:</p>
<p>Add the capabilities to Nmap. Be sure to specify the full path to wherever you installed Nmap:</p>
<p><code class="highlighter-rouge">sudo setcap cap_net_raw,cap_net_admin,cap_net_bind_service+eip /usr/bin/nmap
</code></p>
<p>And you can set up the device tracker as</p>
<div class="language-yaml highlighter-rouge"><pre class="highlight"><code><span class="pi">-</span> <span class="s">platform</span><span class="pi">:</span> <span class="s">nmap_tracker</span>
<span class="s">hosts</span><span class="pi">:</span> <span class="s">192.168.1.1-25</span>
<span class="s">scan_options</span><span class="pi">:</span> <span class="s2">"</span><span class="nv"> </span><span class="s">--privileged</span><span class="nv"> </span><span class="s">-sP</span><span class="nv"> </span><span class="s">"</span>
</code></pre>
