Si vous tentez de <strong>redémarrer/éteindre</strong> une machine distance par <strong>ssh</strong>, vous pourriez constater que votre session ne se termine pas correctement, vous laissant avec un terminal inactif jusquà lexpiration dun long délai dinactivité. Il existe un bogue 751636 à ce sujet. Pour linstant, la solution de contournement à ce problème est dinstaller :</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo apt-get install libpam-systemd # Installé par défaut sur debian buster

<p>Le protocole RPC na pas la réputation dêtre bien sécurisé, mais la version 4 de NFS entend corriger ce problème, elle est donc à privilégier. Il est déconseillé deffectuer un partage NFS via internet, ou bien dans ce cas, opter pour un tunnel crypté.</p>
<ul>
<li>Sassurer que les partages sont réservés à certaines IP dans /etc/exports</li>
<li>Sappuyer sur rpcbind (/etc/hosts.deny et /etc/hosts.allow) pour sécuriser laccès au serveur NFS</li>
<li>Configurer convenablement iptables</li>
</ul>
<p><strong>hosts.deny , hosts.allow</strong><br />
Tout le monde est interdit, puis le LAN est autorisé:</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>echo "rpcbind mountd nfsd statd lockd rquotad : ALL" &gt;&gt; /etc/hosts.deny
echo "rpcbind mountd nfsd statd lockd rquotad: 192.168.0." &gt;&gt; /etc/hosts.allow
</code></pre></div></div>
<p><strong>iptables (NFS)</strong><br />
Par défaut, les différents services NFS (lockd, statd, mountd, etc.) demandent des assignations de ports aléatoires à partir du portmapper (portmap/rpcbind), ce qui signifie que la plupart des administrateurs doivent ouvrir une gamme de ports dans leur base de règles de pare-feu pour que NFS fonctionne.</p>
<p>Il va donc falloir fixer les ports de ces services afin de créer les règles iptables.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>echo 'STATDOPTS="--port 32765 --outgoing-port 32766"' &gt;&gt; /etc/default/nfs-common
echo 'RPCMOUNTDOPTS="-p 32767"' &gt;&gt; /etc/default/nfs-kernel-server
echo 'RPCRQUOTADOPTS="-p 32769"' &gt;&gt; /etc/default/quota
</code></pre></div></div>
<p>Relance sysctl</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sysctl --system

fs.protected_hardlinks = 1
fs.protected_symlinks = 1
* Applying /etc/sysctl.conf ...
</code></pre></div></div>
<p>Relancer le service</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>systemctl restart nfs-kernel-server
</code></pre></div></div>
<p>Voici les règles à fixer dans le parefeu</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>iptables -A INPUT -s 192.168.0.0/24 -p tcp -m multiport --ports 111,2049,32764:32769 -j ACCEPT -m comment --comment "NFS Server"

</code></pre></div></div>
<h3 id="configurer-le-partage-nfs-avec-setgid">Configurer le partage NFS avec SetGID</h3>
<p>Maintenant que le serveur NFS est configuré avec le point de montage NFS de base /srv/nfs, nous devons configurer SetGID dans ce répertoire, comme indiqué ci-dessous.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo chmod 2770 /srv/nfs
</code></pre></div></div>
<p>Cela a également défini les autorisations 770 sur le répertoire, de sorte que lutilisateur racine et le groupe défini disposent dautorisations complètes. Le 2 permet setgid.</p>
<p>Ensuite, nous créons un groupe appelé partage et modifions le répertoire /srv/nfs afin que le propriétaire du groupe soit ce groupe partage.<br />
Nous spécifions également manuellement le GID qui sera utilisé pour le groupe en tant que 9999; il doit sagir dun <u>numéro libre sur votre client et votre serveur</u>.</p>
<p>Exécuter <code class="language-plaintext highlighter-rouge">groupadd</code> sur le client et sur le serveur, et ajouter un utilisateur à ce groupe.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>sudo groupadd -g 9999 partage # sur client et serveur
sudo usermod -a -G partage $USER # sur client et serveur
sudo chgrp partage /srv/nfs # serveur uniquement
</code></pre></div></div>
<blockquote>
<p>NE PAS OUBLIER DE SE DECONNECTER/CONNECTER</p>
</blockquote>
<p>Nous pouvons confirmer que setgid est en place, comme indiqué ci-dessous, où le bit dexécution pour les autorisations de groupe est une minuscule. Cela passera à une majuscule S si le groupe ne dispose pas de lautorisation dexécution et que seul setgid est en place.</p>
<div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>ls -la /srv/nfs/
</code></pre></div></div>
<p>drwxrws— 5 root partage 4096 mars 16 07:57 .</p>
<p>Désormais, tous les fichiers ou répertoires créés dans /srv/nfs se verront automatiquement attribuer le propriétaire du groupe partage, ce qui permettra essentiellement la collaboration de groupe, car tout utilisateur appartenant au groupe partage pourra désormais accéder aux fichiers créés par dautres utilisateurs du groupe. même groupe dans le répertoire /srv/nfs.</p>

<h3 id="blocage-des-dmp-avec-unbound-non-implante">Blocage des DMP avec Unbound (NON IMPLANTE)</h3>
<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)<a href="https://gitea.cinay.eu/yann/blocage-dmp-unbound">https://gitea.cinay.eu/yann/blocage-dmp-unbound</a></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>blocked.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>
