# 什么是监听模式？

监听模式如何捕获无线帧以用于授权 WiFi 分析。

监听模式允许无线适配器捕获附近的 802.11 帧。它支持在特定范围内的 WiFi 评估中进行被动分析。

{% hint style="warning" %}
仅捕获你拥有或已获授权评估的设备上的流量。
{% endhint %}

### 为什么需要它

大多数无线评估工作流程都需要监听模式。适配器在不加入接入点的情况下进行监听。

这会暴露可供检查的无线管理帧和数据帧。它不会授予网络访问权限。

### 你可以观察到什么

监听模式可以显示附近无线流量中的元数据：

* 接入点和客户端的 MAC 地址。
* 网络名称、信道和信号强度。
* 身份验证、关联以及其他管理帧。

### 重要限制

捕获效果取决于距离、信道和适配器支持。若没有所需密钥，加密载荷仍然无法读取。

# 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/zh/hacking-wifi/wpa-wpa2-psk-network-attacks/fundamentals/what-is-monitor-mode.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.
