无线网卡支持的模式[0]

Posted on 2023年11月14日 by

无线网卡一共有4种工作模式。

  • Managed (被管理,即你的无线网卡处理被管理的模式)模式:该模式用于你的无线客户端直接与无线接入点(Access Point,即AP)进行接入连接。在这个模式中,我们可以进行无线接入internet上网,无线网卡的驱动程序依赖无线AP管理整个通信过程。
  • Master (主模式,即你的无线网卡充当AP)模式:一些无线网卡支持Master模式。这个模式允许无线网卡使用特制的驱动程序和软件工作,作为其他设备的无线AP。它主要使用于无线接入点AP提供无线接入服务以及路由功能。比如无线路由器就是工作在Master模式下了,对于普通的pc机来说,如果有合适的硬件它也可以变成一台无线AP。
  • Ad hoc(对等,点对点)模式:当你的网络由互相直连的设备组成时,就使用这个模式。在这个模式中,各设备之间采用对等网络的方式进行连接,无线通信双方共同承担无线AP的职责。
  • Monitor(监视) 模式:Monitor模式主要用于监控无线网络内部的流量,用于检查网络和排错。要使Wireshark捕获无线数据包,你的无线网卡和配套驱动程序必须支持监听模式(也叫RFMON模式,(Radio Frequency MONitor,射频监视器))。Monitor模式是指无线网卡可以接收所有经过它的数据流的工作方式。监听模式不区分所接收数据包的目标MAC地址,这点和混杂模式类似。然而,和混杂模式不同的是,监听模式的不需要和无线接入点(AP)或Ad-hoc网络建立连接。监听模式是无线网卡特有的特殊模式,而混杂模式应用于有线网卡和无线网卡。监听模式通常用于网络发现、流量监听和分组分析。Linux、Mac、OS X、Windows以及其他Unix-like平台有使用监听模式的网络发现、抓包工具,如KisMAC、Kismet、Wireshark、Aircrack-ng等。

大部分用户只使用无线网卡的被管理模式或ad hoc模式
