<p><em>Les serveurs DNS sont des machines discutant entre elles afin de se communiquer les correspondances entre nom de domaine et adresses IP.</em></p>
<h3 id="prérequis">Prérequis</h3>
<p><em>À partir de la version 209, systemd contient un démon de configuration réseau nommé <u>systemd-networkd</u> qui peut être utilisé pour la configuration basique du réseau. De plus, depuis la version 213, la résolution de nom DNS peut être prise en charge par <u>systemd-resolved</u> au lieu dun fichier /etc/resolv.conf statique. <u>Ces deux services sont activés par défaut</u></em></p>
<p class="warning">Si vous utilisez un résolveur local (par exemple bind, dnsmasq, unbound, etc), ou tout autre logiciel générant un fichier <strong>/etc/resolv.conf</strong> (par exemple <strong>resolvconf</strong>), le service <strong>systemd-resolved</strong> ne doit pas être utilisé.<br />
Pour désactiver <strong>systemd-resolved</strong>, exécutez la commande suivante : <code class="language-plaintext highlighter-rouge">sudo systemctl disable systemd-resolved</code><br />
Effacer puis recréer un fichier <code class="language-plaintext highlighter-rouge">/etc/resolv.conf</code> avec une directive dns, par exemple : <code class="language-plaintext highlighter-rouge">nameserver 1.1.1.1</code></p>

<h3 id="blocage-des-dmp">Blocage des DMP</h3>
<p><strong>Blocage des DMP (Data Management Platforms) avec Unbound</strong></p>
<p><em>Configuration nécessaire pour Unbound afin de bloquer certaines “Data Management Platforms” (DMP) utilisées par de plus en plus de sites (liberation.fr, oui.scnf, lemonde.fr, fnac.com…) et qui échappent pour linstant aux bloqueurs de traqueurs traditionnels (uBlock Origin ou uMatrix par exemple)</em></p>
<p><strong>Le cœur du problème</strong> <br />
Dernièrement, une conjoncture déléments est venue semer le trouble chez nos aspirateurs :</p>
<ul>
<li>Lentrée en vigueur du RGPD en Europe</li>
<li>La part de plus en plus grande dinternautes utilisant des bloqueurs de publicités</li>
<li>La volonté des éditeurs de navigateurs web (Chrome et Firefox et donc leurs dérivés) de bloquer par défaut les traqueurs ou les cookies tiers.</li>
</ul>
<p>Un mouchard est dit tiers ou 3rd-party quand on est disruptif quand il nest pas chargé depuis le domaine (ou un de ses sous domaines) que vous visitez. Par exemple quand on visite https://liberation.fr/, le script chargé depuis www.google-analytics.com est tiers. Si le même mouchard est chargé depuis un sous-domaine de liberation.fr, il est dit 1st-party (primaire a priori en bon français).
Le hic, pour nos amis start-uppers est que les mouchards/cookies tiers sont triviaux à bloquer. Ne pas charger les cookies tiers est dailleurs une option répandue dans les navigateurs depuis des années.</p>
<p><strong>La fourberie</strong><br />
La technique développée par les marketeux pour ne pas voir les juteuses données personnelles leur échapper est à la fois techniquement très simple et redoutable. Il suffit de transformer les crasses 3rd-party en 1st-party afin de les cacher sous le cyber-tapis pour reprendre lexpression de Reflets. Et pour se faire passer par le DNS et ses possiblités.</p>
<p><strong>Bloquer les indésirables avec Unbound</strong><br />
On entre dans la partie technique, pour faire court, on va décréter à Unbound que nous contrôlons les domaines indésirables (eulerian.net par exemple) afin de faire échouer la résolution DNS. La technique est <a href="https://www.shaftinc.fr/escalade-traque-eulerian.html">développée plus en détail sur un blog</a>.</p>
<p>Pour mémoire :</p>
<ul>
<li>On crée un fichier de zone (<strong>eulerian.net.zone</strong>) où lon met un enregistrement SOA.</li>
<li>On lassocie à chaque domaine à bloquer dans la configuration dUnbound (<strong>adblock-war.conf</strong>)</li>
</ul>
<p>Cette technique sera valable, pour les versions dUnbound supérieures à 1.7.0.</p>
<p>Créer un fichier <code class="language-plaintext highlighter-rouge">/var/lib/unbound/eulerian.net.zone</code></p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$TTL 10800
eulerian.net. IN SOA localhost. nobody.invalid. (
1
3600
1200
604800
10800
)
</code></pre></div></div>
<p>Dans le détail, on indique la durée de vie par défaut des enregistrements ($TTL 10800) puis le début de lautorité pour la zone (avec le nom du serveur faisant autorité (localhost.), le mail de ladmin (nobody@invalid. le @ est un caractère particulier dans le DNS, on le remplace donc par un point) et cest tout, le reste du domaine sera vide.</p>
<p>créer 2 copies de ce fichier nommées <code class="language-plaintext highlighter-rouge">eulerian.com.zone</code> et <code class="language-plaintext highlighter-rouge">eulerian.fr.zone</code> et changer le domaine.</p>
<p>fichier <code class="language-plaintext highlighter-rouge">/var/lib/unbound/eulerian.com.zone</code></p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>$TTL 10800

1

1200
604800
10800
)
</code></pre></div></div>
<p>Configuration dUnbound</p>
<p>Dans un fichier .conf spécifique, typiquement <code class="language-plaintext highlighter-rouge">/etc/unbound/unbound.conf.d/block-eurelian.conf</code> sous Debian et dérivés, ajouter :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>auth-zone:
name: "eulerian.net."
zonefile: "/var/lib/unbound/eulerian.net.zone"
auth-zone:
name: "eulerian.fr."
zonefile: "/var/lib/unbound/eulerian.fr.zone"
auth-zone:
name: "eulerian.com."
zonefile: "/var/lib/unbound/eulerian.com.zone"
</code></pre></div></div>
<p>On définit donc 3 zones sur lesquelles nous décrétons avoir lautorité et pour chacune dentre elles, on dit à Unbound dutiliser les fichiers correspondants. On sauvegarde et on relance Unbound et normalement, le blocage est effectif :</p>

<ul>
<li>Article original <a href="https://coagul.org/drupal/publication/r%C3%A9solution-noms-resolvconf-sous-linux-debian">Résolution des noms avec resolvconf sous Linux Debian</a> du 27/08/2106</li>
</ul>
<p><em>En fonction du type de connexion utilisé, il est parfois nécessaire de faire appel à différents serveurs de noms (DNS). Par exemple, lors dune connexion à son lieu de travail, il faut utiliser le serveur DNS de son réseau, mais lors dune connexion à internet, il faut utiliser les serveurs DNS de son fournisseur daccès. Dans ce cas, le paquet <strong>“resolvconf”</strong> sous Debian permet de résoudre ces problèmes.</em></p>
<p><strong>Rappel sur lutilité du fichier « /etc/resolv.conf »</strong><br />
Ce fichier permet dindiquer le ou les domaines de recherche et les différents serveurs DNS à utiliser.</p>
<p>Par exemple, dans un réseau local, nous pourrions avoir un serveur DNS à ladresse 192.168.0.1 chargé de gérer le domaine « mon-domaine.local ». En cas de défaillance du DNS local, nous pourrions faire appel aux serveurs DNS de notre fournisseur daccès. Dans ce cas, le contenu du fichier « /etc/resolv.conf », pourrait ressembler à cela :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>nameserver 192.168.0.1
nameserver 212.27.53.252
nameserver 212.27.52.252
search mon-domaine.local
</code></pre></div></div>
<p>La première ligne indique ladresse du serveur DNS du réseau local. En cas de défaillance de ce serveur, les serveurs suivants seront utilisés (Serveurs du fournisseur daccès à Internet).</p>
<p>La dernière ligne permet dindiquer le nom du domaine géré par le serveur DNS local. Par exemple, si nous cherchons à contacter le serveur « <strong>MonServeur</strong> », le système cherchera en fait à contacter ladresse complète « <strong>MonServeur.mon-domaine.local</strong> », car le nom du serveur indiqué ne comportait pas le domaine de recherche.</p>
<p><strong>Présentation et installation de resolvconf</strong><br />
Le programme <strong>resolvconf</strong> garde la trace des informations du système sur les serveurs de noms de domaine actuellement disponibles. Il ne faut pas le confondre avec le fichier de configuration <strong>resolv.conf</strong> qui porte malencontreusement presque le même nom. <u>Le programme resolvconf est optionnel sur les systèmes Debian.</u></p>
<p>Le fichier de configuration <strong>resolv.conf</strong> contient des informations sur les serveurs de noms de domaine que le système doit utiliser. Néanmoins, quand plusieurs programmes doivent modifer dynamiquement le fichier de configuration resolv.conf, ils peuvent se chevaucher et le fichier peut ne plus être synchronisé. Le programme resolvconf soccupe de ce problème. Il agit comme un intermédiaire entre les programmes qui fournissent des informations sur les serveurs de noms de domaine (par exemple les clients dhcp) et les programmes qui les utilisent (par exemple resolver).</p>
<p>Quand <strong>resolvconf</strong> est correctement installé, le fichier de configuration resolv.conf du répertoire <strong>/etc/resolv.conf</strong> est remplacé par un lien symbolique pointant vers le fichier /etc/resolvconf/run/resolv.conf et le résolveur utilise plutôt le fichier de configuration qui est généré dynamiquement par resolvconf à cet emplacement /etc/resolvconf/run/resolv.conf.</p>
<p>Le programme resolvconf est en général seulement nécessaire quand un système a plusieurs programmes qui ont besoin de modifier de façon dynamique les informations sur les serveurs de noms de domaine. Sur un système simple où les serveurs de noms de domaine ne changent pas souvent ou bien ne sont modifiés que par un programme, le fichier de configuration resolv.conf est suffisant.</p>
<p>Si le programme resolvconf est installé, vous naurez pas à modifier à la main le fichier de configuration resolv.conf car il sera changé de façon dynamique par les programmes. Si vous avez besoin de définir vous-même les serveurs de noms de domaine (comme avec une interface statique), ajoutez au fichier de configuration interfaces du répertoire /etc/network/interfaces une ligne comme celle-ci :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>dns-nameservers 127.0.0.1 80.67.169.12 80.67.169.40
</code></pre></div></div>
<p>Mettez la ligne indéntée dans un paragraphe iface, par exemple juste après la ligne gateway. Entrez les adresses IP des serveurs de noms de domaine dont vous avez besoin après dns-nameservers, toutes sur la même ligne, séparées par des espaces. Noubliez pas le “s” à la fin de dns-nameservers.</p>
<p>Le programme resolvconf est un ajout plutôt récent à Debian et plusieurs anciens programmes ont besoin dêtre mis à jour ou reconfigurés pour fonctionner correctement avec lui . Si vous rencontrez des problèmes, regardez <em>/usr/share/doc/resolvconf/README</em> qui contient beaucoup dinformations sur la manière de faire fonctionner resolvconf avec dautres programmes.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>apt install resolvconf -y
echo "nameserver 127.0.0.1" &gt;&gt; /etc/resolvconf/resolv.conf.d/head
</code></pre></div></div>
<blockquote>
<p>Une fois le paquet « <strong>resolvconf</strong> » installé, <u>il ne faut plus modifier le fichier</u> « <strong>/etc/resolv.conf</strong> », car le contenu de celui-ci sera automatiquement géré et remplacé par « <strong>resolvconf</strong> ».</p>
</blockquote>
<p>Le résultat de la commande</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>nslookup afnic.fr | grep Server
</code></pre></div></div>
<p>devrait ressembler à ceci:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>Server: 127.0.0.1
</code></pre></div></div>
<p>Vérifier la résolution de nom à partir du serveur :</p>
