网络管理器也支持消息处理 - 任何位于 `/etc/NetworkManager/dispatcher.d/pre-up.d/` 的脚本在建立网络连接之前都会被执行。
NetworkManager also supports hooks - any script placed in `/etc/NetworkManager/dispatcher.d/pre-up.d/` is run before a connection is brought up.

最后，我查看了 `ifconfig`的输出结果，我发现端口MAC地址已经变成了随机生成的地址，而不是我真实的MAC地址。
As a final check, if I look at `ifconfig` I can see that the `HWaddr` is the spoofed one, not my real MAC address:
