<h2><b>Initial Setup </b></h2>
<p>On your server, edit the torrc file like so:</p>
<pre><code class="nim">
[ Datura ] [ /dev/pts/9 ] [~]
→ cat /etc/tor/torrc
HiddenServiceDir /var/lib/tor/onions/daturab6drmkhyeia4ch5gvfc2f3wgo6bhjrv3pz6n7kxmvoznlkq4yd.onion/
HiddenServicePort 22 127.0.0.1:22
HiddenServicePort 80 127.0.0.1:4443
</code></pre>
<p>Then just edit your local .ssh config to access it:</p>
<pre><code class="nim">
[ mainpc ] [ /dev/pts/7 ] [~]
→ cat .ssh/config
Host web-gw2024-dedi

Host datura

</code></pre>
<p>Then connect to the host via SSH:</p>

<p>So <b>that's how you do it if you cannot access the server via a public IP directly</b>, but keep in mind that the latency is most likely unbearable due to the 6 hops circuit (since we're doing it via the .onion link, rather than connecting to the IP directly)</p>
<p> so you're probably better off just connecting to the IP directly but <b>forcing the SSH connection through tor using torsocks, which greatly reduces the latency (3 hops instead of 6)</b>:</p>
