Ubuntu 14.04 - 绑定 2 个 WIFI 卡

Question

我正在尝试在 Ubuntu 14.04 中绑定 2 个 WIFI 卡。

我已经安装了 ifenslave-2.6，然后更改了 /etc/network/interfaces并添加了一个 /etc/wpa_supplicant0.conf和/etc/wpa_supplicant1.conf 文件 ，如下所示。

不能让它工作，请指教。2 个 WIFI 卡显示已连接，请参阅下面的iwconfig。 还可以在下面找到诊断消息。

我在接口文件中尝试了各种 wpa 细节的变化，在接口中使用 ifenslave 上下，但没有运气。

谢谢你。

/etc/网络/接口

Answer 1

因为大多数与无线网络的“关联”（“物理链路层”上的连接，如插入以太网电缆）是通过MAC 地址完成的完成的，因此欺骗/发送错误的数据包将很棘手

以下提示可能会有所帮助：

• 许多路由器（和网桥）都启用了STP（生成树协议），可以防止链路级别的循环，而且还可以过滤类似您想要的情况（数据包来自路由器不期望的另一个端口）STP 维基百科条目

• 绑定驱动程序中的balance_xx模式需要混杂模式，请参阅此处以将您的wifi卡设置为此模式

• 路由器需要关闭客户端隔离，并且可能还需要修补 hostapd/wpa-supplicant以接受不属于关联 MAC地址的数据包

• 解决方法：尝试使用tinc或gretap 拥有一个 IP 端点，并将该虚拟隧道连接到路由器端的网桥

你无法让它发挥作用，因为这是不可能的
