<h2 id="ntfy">Ntfy</h2>
<h3 id="installation">Installation</h3>
<p>Le CLI de ntfy vous permet de publier des messages, de vous abonner à des sujets et dhéberger vous-même votre propre serveur ntfy. Cest très simple. Il suffit dinstaller le binaire, le paquet ou limage Docker, de le configurer et de lexécuter.</p>
<p class="info">Les étapes suivantes ne sont nécessaires que si vous voulez héberger votre propre serveur ntfy ou si vous voulez utiliser le CLI ntfy. Si vous voulez juste envoyer des messages en utilisant ntfy.sh, vous navez pas besoin dinstaller quoi que ce soit. Vous pouvez simplement utiliser curl.</p>
<p>Le serveur ntfy se présente sous la forme dun binaire lié statiquement et est livré sous forme de paquetage tarball, deb/rpm et sous forme dimage Docker. Nous supportons amd64, armv7 et arm64.<br />
Veuillez consulter la <a href="https://github.com/binwiederhier/ntfy/releases">page des versions</a> pour les binaires et les paquets deb/rpm.</p>

<h3 id="configuration-du-serveur-ntfy">Configuration du serveur ntfy</h3>
<p>Le serveur ntfy peut être configuré de trois manières :</p>
<ol>
<li>Par défaut, en utilisant un fichier de configuration (typiquement dans <code class="language-plaintext highlighter-rouge">/etc/ntfy/server.yml</code>)</li>
<li>via des arguments de ligne de commande</li>
<li>ou en utilisant des variables denvironnement.</li>
</ol>
<h4 id="ntfy-derrière-un-proxy">ntfy derrière un proxy</h4>
<p>Si vous exécutez ntfy derrière un proxy, vous devez activer le drapeau behind-proxy. Cela demandera à la logique de limitation de taux dutiliser len-tête X-Forwarded-For comme identifiant principal dun visiteur, plutôt que ladresse IP distante. Si lindicateur “behind-proxy” nest pas activé, tous les visiteurs seront comptés comme un seul, car du point de vue du serveur ntfy, ils partagent tous ladresse IP du proxy.</p>

<h3 id="instance-privée">Instance privée</h3>
<h4 id="configurer-serveryml">Configurer server.yml</h4>
<p>La façon la plus simple de configurer une instance privée est de définir <code class="language-plaintext highlighter-rouge">auth-default-access: deny-all</code> dans le fichier <code class="language-plaintext highlighter-rouge">/etc/ntfy/server.yml</code> :</p>
<div class="language-yaml highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="na">auth-file</span><span class="pi">:</span> <span class="s">/var/lib/ntfy/user.db</span>

<span class="c1"># web-root: "disable"</span>
</code></pre></div></div>
<p>Explications</p>
<ul>
<li>Listen-http - Le port sur lequel le serveur Web HTTP écoute (par défaut = 80). Vous pouvez également ajouter une adresse IP à laquelle vous connecter (<code class="language-plaintext highlighter-rouge">listen-http : "127.0.0.1:8100"</code>)</li>
<li><strong>auth-file</strong> - Emplacement du user.dbfichier dauthentification.</li>
<li><strong>auth-default-access</strong> - Définir ceci sur <strong>“deny-all”</strong> forcera tous les sujets à être privés par défaut.</li>
<li><strong>behind-proxy</strong> - Si ntfy est déployé derrière un proxy comme Caddy, nginx, etc., alors cela doit être défini sur true.</li>
<li><strong>web-root</strong> - Emplacement du répertoire racine pour ntfy. Le réglage sur « désactiver » désactive le client Web.</li>
</ul>
<p>Redémarrer le serveur ntfy</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo systemctl restart ntfy
</code></pre></div></div>
<h4 id="créer-utilisateur">Créer utilisateur</h4>
<p>Passer en mode su : <code class="language-plaintext highlighter-rouge">sudo -s</code></p>
<p><strong>Créer utilisateur dans NTFY</strong> (<a href="https://docs.ntfy.sh/config/#users-and-roles">Users and roles</a>)<br />
Puisque nous avons déjà défini l attribut <code class="language-plaintext highlighter-rouge">auth-file</code> et <code class="language-plaintext highlighter-rouge">auth-default-access</code>, nous pouvons passer à lajout de notre premier utilisateur administrateur “notif”.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ntfy user add --role=admin notif
</code></pre></div></div>
<p>Lappel de cette commande avec un nom dutilisateur vous invitera automatiquement à créer un mot de passe pour le nouvel utilisateur.<br />
Saisir un mot de passe pour “notif”<br />
<code class="language-plaintext highlighter-rouge">user leno added with role admin</code></p>
<p>Une fois lutilisateur créé, nous pouvons labonner à notre premier sujet de notification.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ntfy access notif notif_infos rw
</code></pre></div></div>
<p>Explications</p>
<ul>
<li><strong>rw</strong> spécifie le niveau daccès de lutilisateur <strong>notif</strong> pour le sujet <strong>notif_infos</strong>. Puisque cet utilisateur sera utilisé pour envoyer des notifications, nous devons lui donner la possibilité décrire sur le sujet.</li>
<li><strong>wo</strong> “write-only” (écriture seule)</li>
<li><strong>rw</strong> “read-write” (lecture-écriture)</li>
<li><strong>ro</strong> “read-only” (lecture seule)</li>
</ul>
<p>Vous pouvez modifier les autorisations daccès à tout moment, en réexécutant la commande ci-dessus avec un niveau daccès différent.</p>
<p>Créez maintenant un deuxième utilisateur <strong>notifmob</strong> avec les autorisations sur le sujet en lecture seul.<br />
Ce deuxième utilisateur sera utilisé pour notre application mobile.</p>

<p>Une fois que vous avez fait cela, vous pouvez publier et vous abonner en utilisant lauthentification de base avec le nom dutilisateur/mot de passe donné. Veillez à utiliser HTTPS pour éviter les écoutes et lexposition de votre mot de passe.</p>

<p><a href="https://docs.ntfy.sh">Doc ntfy</a></p>
<h3 id="utilisateur--mot-de-passe">Utilisateur + mot de passe</h3>
<p><a href="https://docs.ntfy.sh/publish/#username-password">Username + password</a><br />
Lorsque lagent utilisateur souhaite envoyer des informations dauthentification au serveur, il peut utiliser le champ den-tête <strong>Authorization</strong></p>
<p>Le champ den-tête <strong>Authorization</strong> est construit comme suit :</p>
<ul>
<li>Le nom dutilisateur et le mot de passe sont combinés avec un seul deux-points ( <code class="language-plaintext highlighter-rouge">:</code>). Cela signifie que le nom dutilisateur lui-même ne peut pas contenir de deux points.</li>
<li>La chaîne résultante est encodée en une séquence doctets. Le jeu de caractères à utiliser pour cet encodage est par défaut non spécifié, tant quil est compatible avec US-ASCII, mais le serveur peut suggérer lutilisation dUTF-8 en envoyant le paramètre charset.</li>
<li>La chaîne résultante est encodée à laide dune variante de Base64 (+/ et avec remplissage).</li>
<li>La méthode dautorisation et un caractère despacement (par exemple “Basic “) sont ensuite ajoutés à la chaîne encodée.</li>
</ul>
<p>Par exemple, si le navigateur utilise <em>Aladdin</em> comme nom dutilisateur et <em>open sesame</em> comme mot de passe, la valeur du champ est le codage Base64 de <em>Aladdin:open sesame</em>, ou <em>QWxhZGRpbjpvcGVuIHNlc2FtZQ==</em>. Le champ den-tête Authorization se présente alors comme suit :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==
</code></pre></div></div>
<p>Pour générer len-tête dautorisation, utilisez la norme base64 pour encoder les <code class="language-plaintext highlighter-rouge">&lt;nom d'utilisateur&gt;:&lt;mot de passe&gt;</code> séparés par deux points et ajoutez-y le mot Basic, cest-à-dire Authorization : Basic base64(<code class="language-plaintext highlighter-rouge">&lt;username&gt;:&lt;password&gt;</code>).<br />
Voici un pseudo-code qui, je lespère, lexplique mieux :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>username = "testuser"
password = "fakepassword"
authHeader = "Basic " + base64(username + " :" + password) // -&gt; Basic dGVzdHVzZXI6ZmFrZXBhc3N3b3Jk
</code></pre></div></div>
<p>La commande suivante génère la valeur appropriée pour vous sur les systèmes *nix :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>echo "Basic $(echo -n 'testuser:fakepassword' | base64)"
</code></pre></div></div>
<p>INFO: Entête autorisation au format <strong>utilisateur:Mot_de_passe</strong> base 64 <br />
<code class="language-plaintext highlighter-rouge">echo -n 'leno:mot de passe' | base64</code><br />

<h3 id="jetons-tokens">Jetons (Tokens)</h3>
<p><em>Le jeton peut être utilisé à la place du nom dutilisateur et du mot de passe lors de lenvoi de messages. (<a href="https://docs.ntfy.sh/config/#access-tokens">Access tokens</a>)</em></p>
<p>En plus de lauthentification par nom dutilisateur/mot de passe, ntfy fournit également une authentification par jetons daccès. Les jetons daccès sont utiles pour éviter davoir à configurer votre mot de passe dans plusieurs applications de publication/abonnement. Par exemple, vous pouvez utiliser un jeton dédié pour publier à partir de votre hôte de sauvegarde, et un autre à partir de votre système domotique.</p>
<p>Vous pouvez créer des jetons daccès en utilisant la commande <code class="language-plaintext highlighter-rouge">ntfy token</code>, ou dans lapplication web dans la section “Compte” (lorsque vous êtes connecté). Voir les <a href="https://docs.ntfy.sh/config/#access-tokens">jetons daccès</a> pour plus de détails.</p>
<p>Une fois le jeton daccès créé, vous pouvez lutiliser pour vous authentifier auprès du serveur ntfy, par exemple lorsque vous publiez ou vous abonnez à des sujets.</p>
<p>La commande ntfy token permet de gérer les jetons daccès des utilisateurs. Les jetons peuvent avoir des étiquettes, et ils peuvent expirer automatiquement (ou ne jamais expirer). Chaque utilisateur peut avoir jusquà 20 jetons (codés en dur).</p>
<p>Exemples de commandes (tapez ntfy token help ou ntfy token COMMAND help pour plus de détails)</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ntfy token list # Affiche la liste des jetons pour tous les utilisateurs
ntfy token list phil # Affiche la liste des jetons de l'utilisateur phil
