cf-auto-passwall.sh

#!/bin/bash

# 使用说明：加在 openwrt 上系统 计划任务里 添加定时运行，如 0 4 * * 2,4,6 bash /root/cf-auto-passwall.sh > /dev/null
# 0 4 * * 2,4,6 的意思是在每周二、周四、周六的凌晨4点会自动运行一次。/root/cf-auto-passwall.sh 是你脚本的绝对地址

#########################################注意注意注意注意注意############################################

# 1、请在脚本中修改你期望优选 IP 的带宽大小（默认5M）

# 2、请更改 422 行 的 xxxxxxxxxx 字符串，为你自己 PassWall 的节点值（不会请看视频教程或是博客）
