This is supposed to work between two servers and one client: a server in charge of creating, signing and verifying the certificates, a server with the OpenVPN service running and the client making the request.</p> <p>This is supposed to work something like: 1) a client wants to use the VPN service, so it creates a requests and sends it to the signing server, 2) this server checks the requests and signs the request, returning the certificates to both the VPN service and the client and 3) the client can now connect to the VPN service using the signed certificate which the OpenVPN server knows about. In a nutshell, I’m no expert.</p> <p>… but, to be honest, all of this is a hassle and (in my case) I want something simple to use and manage. So I’m gonna do all on one server and then just give away the configuration file for the clients, effectively generating files that anyone can run and will work, meaning that you need to be careful who you give this files (it also comes with a revoking mechanism, so no worries).</p> @@ -129,7 +128,7 @@ openssl dhparam -out dh.pem 2048 openvpn --genkey secret ta.key </code></pre> <p>That’s it for the PKI stuff and general certificate configuration.</p> -<h2 id="openvpn">OpenVPN</h2> +<h3 id="openvpn">OpenVPN<a class="headerlink" href="#openvpn" title="Permanent link">¶</a></h3> <p><a href="https://wiki.archlinux.org/title/OpenVPN">OpenVPN</a> is a robust and highly flexible VPN daemon, that’s pretty complete feature wise.</p> <p>Install the <code>openvpn</code> package:</p> <pre><code class="language-sh">pacman -S openvpn @@ -277,7 +276,7 @@ ufw reload systemctl enable openvpn-server@server.service </code></pre> <p>Where the <code>server</code> after <code>@</code> is the name of your configuration, <code>server.conf</code> without the <code>.conf</code> in my case.</p> -<h3 id="create-client-configurations">Create client configurations</h3> +<h4 id="create-client-configurations">Create client configurations<a class="headerlink" href="#create-client-configurations" title="Permanent link">¶</a></h4> <p>You might notice that I didn’t specify how to actually connect to our server.
