原理

通过 dns日志来获得目标,通过nf_conntrack 80/443判断是否允许httping,允许的整个域名所有ip进行httping,如果超时或者rst,将结果加入ipset gfwlist,并且重试httping,如果不可用会取消加入ipset gfwlist

安装

openwrt 免手动https://github.com/rufengsuixing/luci-app-autoipsetadder
依赖:httping,awk,ipset,curl,tail,stdbuf
安装httping:opkg install httping
安装stdbuf:opkg install coreutils-stdbuf

  • 二选一设置dns服务器日志记录:
    • smartdns:
    audit-enable yes
    audit-file /var/log/smartdns-audit.log
    audit-size 64K
    
    • dnsmasq:
      以下开启dnsmasq的dns日志,并调整到需要的详细程度
    uci set dhcp.@dnsmasq[0].logfacility='/tmp/dnsmasq.log'
    uci delete dhcp.@dnsmasq[0].logqueries
    echo log-queries >> /etc/dnsmasq.conf
    uci commit dhcp
    
  • 对应你的dns服务程序复制autoaddlist.sh,testip.sh,delayretest.sh到/usr/bin/
  • 修改权限
    chmod 755 /usr/bin/autoaddlist.sh
    chmod 755 /usr/bin/testip.sh
    chmod 755 /usr/bin/delayretest.sh
    
  • 手动运行/usr/bin/autoaddlist.sh &
    或者记录日志nohup /usr/bin/autoaddlist.sh >>/tmp/nohup.out &
  • crontab备用指令: 每小时删除日志
    0 * * * * rm -f /tmp/log/smartdns*.gz
    0 * * * * echo "" > /tmp/dnsmasq.log
    
    停止指令备用:
    killall tail
    killall awk
    
  • debug用于寻找ipset gfwlist中的符合ipset china ip在/tmp/nohup.out中的日志
    debugip.sh

本程序输出日志:

输出 解释
[ip] [domain] is in gfwlist pass" ip已经在ipset里
[ip] [domain] [port] 记录检测到的可httping
[浮点数值]/failed, httping得到的延迟结果,异步结果无参考价值
can not connect autoaddip [ip] [domain] 直连无回应超时
doname rst autoaddip [ip] [domain] 疑似直连rst
proxy can not connect autodelip [ip] [domain] ipset后连接无回应超时
doname proxy rst autodelip [ip] [domain] 疑似ipset后连接rst
direct so slow autoaddip [ip] [domain] 直连有回应3s超时
direct Connection refused autoaddip [ip] [domain] 直连拒绝连接
change back to direct [ip] [domain] 尝试都失败或者都3s超时
direct ssl so slow autoaddip [ip] [domain] httping超时无效bug被触发,ssl时间很久但成功了
pass by packets=[number] [ip] [domain] 实验性质,在请求前看已经发送的包的数量>12放过
[ip] [domain] pass by same domain ok 如果有一个可连接同域名ip放过
warning china [ip] [domain] is in gfwlist 检测到china ipset与gfwlist重合
ping packet loss autoaddip [ip] [domain] httping成功后,ping 5个包,返回收到1-3个包触发

注:同ip如果httping过不会重复探测,也不会有日志。
[ ]httping在ssl上有问题,包括超时失效卡住和cloudflare的兼容不好,考虑之后用curl全部重写
