Wireshark: The capture session could not be initiated on interface

Wireshark是個不錯的抓包工具，可以捕獲HTTP，TCP和UDP的包，對於前後端開發非常有用。在Mac上安裝完Wireshark之後提示如下錯誤：The capture session could not be initiated on interface 'en0' (You don't have permission to capture on that device).

查了一圈資料，發現是沒有權限查看/dev/bfp*這些文件夾造成的。於是修改文件夾解決了問題。

sudo chmod o+r /dev/bpf*
