Wireshark: The capture session could not be initiated on interface

Wireshark是个不错的抓包工具，可以捕获HTTP，TCP和UDP的包，对于前后端开发非常有用。在Mac上安装完Wireshark之后提示如下错误：The capture session could not be initiated on interface 'en0' (You don't have permission to capture on that device).

查了一圈资料，发现是没有权限查看/dev/bfp*这些文件夹造成的。于是修改文件夹解决了问题。

sudo chmod o+r /dev/bpf*
