主要的原因是需要在电脑上同时连接内外网的时候，每次都需要在我所使用的 Wi-Fi 网卡上附加一个我们内网的 IP：172.28.20.1/16 之后再加上一个路由。但是每次重启电脑后都得重新添加。当然，我们可以以脚本的形式在登录时进行执行，或者用 automator 建立一个小程序，给用户进行 LoginItems 内弄上。但这觉得都不是根本的解决办法。
一句话介绍
networksetup 是在系统偏好设置中对网络设定进行配置的工具。 networksetup 命令最少需要
admin 权限。 大多数的配置命令都需要 root 权限。
在任何需要密码的地方，可以用
- 代替，表示从标准输入读入密码。概要
