# Analyse des paquets de réponse d’association

Analyser les paquets de réponse d’association dans une capture sans fil autorisée.

Une réponse d’association est envoyée après que le client a soumis une requête d’association. Cette page montre comment identifier ces paquets et examiner leurs adresses MAC dans une capture.

Analysez des captures provenant de réseaux que vous possédez ou que vous êtes autorisé à évaluer.

### Filtrer les réponses d’association

Utiliser le sous-type `1` pour filtrer les paquets de réponse d’association :

{% code overflow="wrap" %}

```bash
tshark -r CAPTURE-01.cap -Y "wlan.fc.type_subtype==1" 2>/dev/null
```

{% endcode %}

Les résultats montrent des paquets de réponse d’association.

### Lister les adresses MAC

Pour lister les adresses MAC dans les réponses d’association, utilisez :

{% code overflow="wrap" %}

```bash
tshark -r CAPTURE-01.cap -Y "wlan.fc.type_subtype==1" -Tfields -e wlan.addr 2>/dev/null | tr ',' '\n' | sort -u
8e:60:c4:67:1c:9f
```

{% endcode %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/fr/hacking-wifi/wpa-wpa2-psk-network-attacks/packet-analysis/association-response-packet-analysis.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
