+# WIRESHARK
+
+[![WIRESHARK](img/ws-logo.svg)](https://www.wireshark.org/)
+
+Comment installer Wireshark et capturer le traffic réseau d'un serveur distant via SSH.
+
+### Installation
+
+```bash
+sudo apt install wireshark tcpdump -y
+```
+> Note: A installer sur le serveur ainsi que sur la machine cliente "streamant" le flux réseau.
+
+### Configuration
+
+- Ajouter l'utilisateur au groupe wireshark
+```bash
+sudo usermod -aG wireshark $USER
+```
+
+- Récupérer l'interface réseau du serveur distant:
+```bash
+ssh -p 2222 remote-user@123.45.67.89
+# L'interface connectée au réseau est celle qui donne l'adresse IP publique
+ip a
+```
+
+> Note: Il est préférable d'avoir éffectué l'échange de clefs SSH via la commande:
+```bash
+ssh-copy-id remote-user@server-ip
+```
+
+#### Interface Wireshark
+
+- Cliquer sur SSH remote capture dans le menu Capture:
+
+![WS](img/ws1.png)
+
+- Entrer l'adresse IP publique du serveur ainsi que le port SSH de connection:
+
+![WS](img/ws2.png)
+
+- Entrer le nom de l'utilisateur distant du serveur ainsi que le chemin vers la clef SSH privée:
+
+![WS](img/ws3.png)
+
+- Renseigner l'interface du serveur distant dans Remote interface ainsi que dans la remote command:
+
+![WS](img/ws4.png)
+
+> Note: Il est d'usage d'ajouter l'argument 'not(host server-IP and port SSH)' pour ne pas polluer la capture avec le traffic généré par la connection au serveur.
+
+Le remote filter se configure automatiquement à la première connection pour enlever le traffic du loopback (127.0.0.1) ainsi que de la machine cliente capturant le flux du serveur.
