<p><em>Dig ( <a href="https://en.wikipedia.org/wiki/Dig_(command)">Domain Information Groper</a> ) est un utilitaire de ligne de commande qui effectue une recherche DNS en interrogeant les serveurs de noms et en affichant le résultat. Dans ce tutoriel, vous trouverez toutes les utilisations de base de la commande que vous devez connaître dans le système dexploitation Linux.</em></p>
<p>Par défaut, dig envoie la requête <a href="https://www.hostinger.com/tutorials/what-is-dns">DNS</a> aux serveurs de noms répertoriés dans le résolveur (/etc/resolv.conf) à moins quil ne lui soit demandé dinterroger un serveur de noms spécifique.</p>
<h2 id="installer-dig-sur-linux">Installer Dig sur Linux</h2>
<p>Dig fait partie du package dutilitaires DNS qui est souvent installé avec des serveurs de noms BIND. Vous pouvez également installer le package dutilitaires qui contient dig séparément en accédant à votre VPS via SSH et en utilisant les commandes suivantes dans la ligne de commande:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>apt-get install dnsutils # Debian et Ubuntu
yum install bind-utils # CentOS 7
pacman -S bind-utils # archlinux
</code></pre></div></div>
<p>Une fois installé, vérifiez la version, pour vous assurer que la configuration sest terminée avec succès:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig -v
</code></pre></div></div>
<h2 id="syntaxe-dig">Syntaxe Dig</h2>
<p>Dans sa forme la plus simple, la syntaxe de lutilitaire dig ressemblera à ceci:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig [serveur] [nom] [type]
</code></pre></div></div>
<p>[serveur] - ladresse IP ou le nom dhôte du serveur de noms à interroger.</p>
<p>Si largument serveur est le nom dhôte, dig résoudra le nom dhôte avant de poursuivre linterrogation du serveur de noms.<br />
Il est facultatif et si vous ne fournissez pas dargument serveur, alors dig utilise le serveur de noms répertorié dans <strong>/etc/resolv.conf</strong></p>
<p>[nom] - le nom de lenregistrement de ressource à rechercher.</p>
<p>[type] - le type de requête demandé par <code class="language-plaintext highlighter-rouge">dig</code>. Par exemple, il peut sagir dun enregistrement <strong>A</strong>, dun enregistrement <strong>MX</strong>, dun enregistrement <strong>SOA</strong> ou de tout autre type. Par défaut, <code class="language-plaintext highlighter-rouge">dig</code> effectue une recherche pour un enregistrement <strong>A</strong> si aucun argument de type nest spécifié.</p>
<h2 id="comment-utiliser-la-commande-dig">Comment utiliser la commande Dig</h2>
<p>Permet dentrer dans les utilisations de base de la commande</p>
<h3 id="dig-un-nom-de-domaine">dig un nom de domaine</h3>
<p>Pour effectuer une recherche DNS pour un nom de domaine, passez simplement le nom avec la commande dig:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig hostinger.com
</code></pre></div></div>
<p>Par défaut, la commande <code class="language-plaintext highlighter-rouge">dig</code> affichera lenregistrement A lorsquaucune autre option nest spécifiée. La sortie contiendra également dautres informations telles que la version dig installée, des détails techniques sur les réponses, des statistiques sur la requête, une section de questions ainsi que quelques autres.</p>
<h3 id="réponses-courtes">Réponses courtes</h3>
<p>La commande <code class="language-plaintext highlighter-rouge">dig</code> ci-dessus comprend de nombreuses informations utiles dans différentes sections, mais il peut arriver que vous ne souhaitiez que le résultat de la requête. Vous pouvez le faire en utilisant loption <code class="language-plaintext highlighter-rouge">+short</code>, qui affichera ladresse IP (enregistrement A) du nom de domaine uniquement:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig hostinger.com +short
</code></pre></div></div>
<h3 id="réponses-détaillées">Réponses détaillées</h3>
<p>Parfois, vous souhaitez afficher la section des réponses en détail. Par conséquent, pour une information détaillée sur la section des réponses, vous pouvez arrêter dafficher toute la section en utilisant loption <code class="language-plaintext highlighter-rouge">+noall</code> et interroger la section des réponses uniquement en utilisant loption <code class="language-plaintext highlighter-rouge">+answer</code> avec la commande <code class="language-plaintext highlighter-rouge">dig</code>.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig hostinger.com +noall +answer
</code></pre></div></div>
<p>Spécification des serveurs de noms</p>
<p>Par défaut, les commandes <code class="language-plaintext highlighter-rouge">dig</code> interrogeront les serveurs de noms répertoriés dans <strong>/etc/resolv.conf</strong> pour effectuer une recherche DNS pour vous. Vous pouvez modifier ce comportement par défaut en utilisant le symbole <code class="language-plaintext highlighter-rouge">@</code> suivi dun nom dhôte ou dune adresse IP du serveur de noms.</p>
<p>La commande dig suivante envoie la requête DNS au serveur de noms de Google (8.8.8.8) en utilisant loption <code class="language-plaintext highlighter-rouge">@ 8.8.8.8</code></p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig @8.8.8.8 hostinger.com
</code></pre></div></div>
<h3 id="interroger-tous-les-types-denregistrement-dns">Interroger tous les types denregistrement DNS</h3>
<p>Pour interroger tous les types denregistrement DNS disponibles associés à un domaine, utilisez loption <code class="language-plaintext highlighter-rouge">ANY</code> qui inclura tous les types denregistrement disponibles dans la sortie:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig hostinger.com ANY
</code></pre></div></div>
<h3 id="rechercher-le-type-denregistrement">Rechercher le type denregistrement</h3>
<p>Si vous souhaitez rechercher un enregistrement spécifique, ajoutez simplement le type à la fin de la commande.</p>
<p>Par exemple, pour rechercher uniquement la section déchange de courrier - <strong>MX</strong> - réponse associée à un domaine, vous pouvez utiliser la commande dig suivante:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig hostinger.in MX
</code></pre></div></div>
<p>De même, pour afficher les autres enregistrements associés à un domaine, spécifiez le type denregistrement à la fin de la commande <code class="language-plaintext highlighter-rouge">dig</code>:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig hostinger.com txt (Query TXT record)
dig hostinger.com cname (Query CNAME record)
dig hostinger.com ns (Query NS record)
dig hostinger.com A (Query A record)
</code></pre></div></div>
<h3 id="tracer-le-chemin-dns">Tracer le chemin DNS</h3>
<p>Dig permet de tracer le chemin de recherche DNS en utilisant loption <code class="language-plaintext highlighter-rouge">+trace</code> . Loption effectue des requêtes itératives pour résoudre la recherche de nom. Il interrogera les serveurs de noms à partir de la racine et parcourt ensuite larborescence de lespace de noms à laide de requêtes itératives suivant les références en cours de route:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig hostinger.com +trace
</code></pre></div></div>
<h3 id="recherche-dns-inversée">Recherche DNS inversée</h3>
<p>La recherche DNS inversée vous permet de rechercher le domaine et le nom dhôte associés à une adresse IP. Pour effectuer une recherche DNS inversée à laide de la commande dig, utilisez loption <code class="language-plaintext highlighter-rouge">-x</code> suivie de ladresse IP choisie. Dans lexemple suivant, dig effectuera une recherche DNS inversée pour ladresse IP associée à google.com:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig +answer -x 172.217.166.46
</code></pre></div></div>
<p>Noubliez pas que si un enregistrement PTR nest pas défini pour une adresse IP, il nest pas possible deffectuer une recherche DNS inversée car lenregistrement PTR pointe vers le domaine ou le nom dhôte.</p>
<h3 id="requêtes-par-lots">Requêtes par lots</h3>
<p>Avec lutilitaire dig, vous pouvez effectuer une recherche DNS pour une liste de domaines au lieu de la faire individuellement. Vous devez fournir à dig une liste de noms de domaine , un par ligne, dans un fichier. Une fois le fichier prêt, spécifiez son nom avec loption <code class="language-plaintext highlighter-rouge">-f</code></p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>nano domain_name.txt
</code></pre></div></div>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>hostinger.com
google.com
ubuntu.com
</code></pre></div></div>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dig -f domain_name.txt +short
</code></pre></div></div>
<h3 id="contrôle-du-comportement-de-dig">Contrôle du comportement de dig</h3>
<p>La sortie de la commande peut être personnalisée en permanence en définissant des options dans le fichier <strong>~/.digrc</strong> qui sexécuteront automatiquement avec la commande.</p>
<p>Supposons que vous souhaitiez afficher uniquement la section des réponses - spécifiez les options requises dans le fichier <strong>~/.digrc</strong>, afin de ne pas avoir à les saisir lors de lexécution de la requête.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>echo "+noall +answer" &gt; ~/.digrc
</code></pre></div></div>
<p>Effectuez maintenant une recherche de serveur DNS pour un domaine. La sortie confirme que dig sexécute avec les options définies dans le fichier <strong>~/.digrc</strong></p>
<h2 id="conclusion">Conclusion</h2>
<p>Cest tout ce dont vous avez besoin pour commencer à utiliser <strong>dig</strong> In Linux. Vous pouvez désormais effectuer des recherches <strong>DNS</strong> pour les domaines à laide de diverses options.<br />
Consultez la page de manuel en utilisant la commande man dig pour découvrir toutes les utilisations et options possibles.</p>
