Article original : <a href="https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point?view=all">Setting up a Raspberry Pi as a WiFi access point</a></p>
<p>Voulez-vous utiliser votre Pi comme routeur WiFi? Ou peut-être lavoir comme point daccès de filtrage spécial? La configuration dun Pi en tant que point daccès est un peu plus avancée que son utilisation en tant que client, mais il ne lui reste quune demi-heure à taper pour la configurer. Si vous le souhaitez, grâce à ce didacticiel, le Pi diffuse un service WiFi puis achemine le trafic Internet vers un câble Ethernet. Comme cest tout Linux, vous pouvez y aller et le mettre à jour ou le configurer comme bon vous semble.</p>
<p>Jai utilisé les pages suivantes comme guide pour créer ce didacticiel; veuillez noter que nombre dentre elles ne fonctionneront pas complètement, mais vérifiez si vous êtes intéressé!</p>

<p>maintenant que nous savons que cela fonctionne, il est temps de le configurer en tant que “démon” - un programme qui démarrera lorsque le Pi démarrera.<br />
Lancer les commandes suivantes:<br />

<h3 id="connecter-et-tester">Connecter et tester</h3>
<p>Maintenant que le logiciel est installé sur un Pi, il est temps de sy connecter et de tester la connexion. Jutilise un ordinateur Windows mais tout type devrait bien fonctionner</p>
<p>Sur le Pi, exécutez la commande tail -f / var / log / syslog pour afficher les données du journal système, ce qui est pratique pour vérifier et déboguer ce qui se passe!</p>
<p>Connectez-vous avec un autre ordinateur au point daccès créé à létape précédente.</p>
<p><img src="/images/raspberry_pi_connectAP.gif" alt="" /></p>
<p>Entrez la clé WPA que vous avez spécifiée à létape précédente.</p>
<p><img src="/images/raspberry_pi_key.gif" alt="" /></p>
<p><img src="/images/raspberry_pi_connecting.gif" alt="" /></p>
<p>Dans le syslog Pi, vous devriez voir des choses comme ça! Il indique quun client sest connecté, à quelle heure et quelle adresse IP lui a été donnée</p>
<p>Si vous ne pouvez pas vous connecter du tout, quelque chose ne va pas avec <strong>hostapd</strong></p>
<p><img src="/images/raspberry_pi_tailf.gif" alt="" /></p>
<p>Sur votre ordinateur, ouvrez un Terminal (mac / linux) ou Démarrer-&gt; Exécuter-&gt; cmd pour ouvrir une ligne de commande.</p>
<p>Commencez par vérifier ce que ifconfig (mac / linux) ou ipconfig (windows) dit. Vous devriez avoir une adresse IP dans la plage 192.168.42.10-50</p>
<p><img src="/images/raspberry_pi_ipconfig.gif" alt="" /></p>
<p>Essayez denvoyer une requête ping au Pi. Son adresse est 192.168.42.1 . Sous Windows, elle sonnera 3 fois et sarrêtera. Sur mac / linux, appuyez sur Control-C pour quitter après quelques pings. Vous devriez avoir des pings réussis comme vu ci-dessous</p>
<p>Si cela ne fonctionne pas, quelque chose ne va pas avec <strong>hostapd</strong> ou <strong>dhcpd</strong> (plus probable)</p>
<p><img src="/images/raspberry_pi_ping192.gif" alt="" /></p>
<p>Ensuite, essayez le <code class="language-plaintext highlighter-rouge">ping 8.8.8.8</code> , si cela ne fonctionne pas mais que le précédent fonctionne, il y a un problème avec <strong>dhcpd</strong> ou la configuration NAT (plus probablement).</p>
<p><img src="/images/raspberry_pi_ping8888.gif" alt="" /></p>
<p>Pour finir, nous allons vérifier que le DNS fonctionne, essayez de faire un ping sur www.mit.edu . Si cela ne fonctionne pas, il y a un problème avec dhcpd</p>
<p>Si tout va bien jusquà présent, essayez de naviguer sur Internet, denvoyer des emails, etc. Vous utilisez maintenant votre Pi comme routeur Wifi!</p>
