定时获取公网ip并发送邮件提醒

article 2024/11/17 9:52:48

前一段时间路由器刷的老毛子固件“穿透服务”中定时更新阿里DDNS失败了，用了很久第一次遇到。所以需要做个备用的措施用来实时获取公网ip信息

1、基于python实现

  • 开启邮箱的SMTP功能
  • 拿到授权码(不是登录密码)

2、创建bat文件启动脚本

"D:\Program Files\Python310\python.exe" D:\Code\Code\sendWANIP\sendWANIP.py

3、Windows任务计划

添加windows任务计划，每隔10分钟执行bat文件获取公网ip
注意：

  • “程序或脚本”中写的可执行文件不要被引号包裹
  • 起始位置必填，为可执行文件所在的目录否则无法执行

4、shell脚本

路由器上跑的shell脚本，百度得来的出处忘记了，有需要的可以参考

#!/bin/bash
 
#SMTP配置   #（例子）
#SMTP服务器#smtpserver=smtp.126.com
#邮箱账号#fromaddress=xxxxxx@126.com
#邮箱密码fromaddresspwd=xxxxxxxxxxxxx
#收件人信息#toaddress=xxxxxx@qq.com 英文逗号分隔
 
 
 
#SMTP配置
smtpserver=smtp.163.com
fromaddress=xxxx@163.com
fromaddresspwd=xxxxxxxxxxxxx
toaddress=xxxxx@163.com
 
 
 
#文件路径，最新ip写入lastwanip.txt 
iptxt="/etc/storage/lastwanip.txt"
#文件路径，邮件正文，写入mail文件
mailtxtpath="/etc/storage/mail.txt"
 
 
 
 
#获取WANIP接口
newwanip=`wget http://members.3322.org/dyndns/getip -q -O -`
 
 
 
 
#如接口获取不到ip，本次取消发送
echo $newwanip
 
if [ x"$newwanip" = "x" ]; then
  newwanip=`wget https://ifconfig.me/ip -q -O -`
  echo $newwanip
  if [ x"$newwanip" = "x" ]; then
    exit
  fi
fi
 
if [ -f $iptxt ]; then
  oldwanip=`cat $iptxt`
else
  oldwanip="0.0.0.0"
fi
 
 
 
 
 
#对比上次IP，如相同则不发邮件，否则发送
echo $oldwanip
 
if [ "$newwanip" = "$oldwanip" ]; then
  exit
fi
if [ -f $mailtxtpath ]; then
  rm -f $mailtxtpath
fi
 
 
 
 
 
#配置邮件标题，修改“wanip”和在${newwanip} 后面加参数
#不能修改代码格式，行与行之间必须空格！
cat  <<EOF >>$mailtxtpath
Subject: WANIP:[ ${newwanip} ]
 
路由器型号 = RedMi AC2100
 
IP=    ${newwanip}
 
ok
 
To: $toaddress
From: $fromaddress
EOF
 
 
 
 
 
#调用系统邮件服务
sendmail -f $fromaddress -t $toaddress -S $smtpserver -au$fromaddress -ap$fromaddresspwd < $mailtxtpath
 
 
 
 
#缓存最新ip地址，写入/etc/storage/lastwanip.txt"
echo $newwanip > $iptxt
 
 
 
 
#打印系统日志，调用logger接口
logger 发现WANIP变化，外网IP= $newwanip 
logger （$fromaddress）已邮件通知（$toaddress）
