Python 路由器IP变革邮件通知
添加时间:2013-6-1 点击量:比来碰到一个题目:实验室内部的收集是经由过程路由器分派IP的,然则经常又须要经由过程校园网长途实验室内部的电脑,而路由器的外网IP是由DHCP办事器动态分派的,IP地址无法绑定成静态的。RadminViewer长途的速度斗劲快,然则没办法穿墙,必须知道直连的IP地址,经由过程在实验室的路由器上设置转发端口,就可以实实际验室内部多台电脑同时长途。然则因为路由器上IP会变,天然想到在办事器上运行一个法度,每隔一段时候监测下路由器的IP,若是变更,就发送邮件通知。
应用Python编写,因为是一个后台的法度,天然想到要做出办事,就不会有窗口一向显示。将Python法度以Windows 办事体式格式启动,须要用到pywin32。
底本想实现可以获取每一层的IP,因为收集可能经过了多层的IP地址转换。但还不知道怎么做,最后参考了这里的办法后,今朝是只能针对TP-Link的路由器获取外网IP,其他路由器没测试过。
后面还可以进一步扩大,实现很多功能,然后可以发邮件通知。应用的时辰,须要先安装办事,然后再启动。办事安装后,默认是手动启动,若是须要设置为主动启动,还须要到Windows经管对象,办事设置中,将该办事设置为主动启动。

我们永远不要期待别人的拯救,只有自己才能升华自己。自己已准备好了多少容量,方能吸引对等的人与我们相遇,否则再美好的人出现、再动人的事情降临身边,我们也没有能量去理解与珍惜,终将擦肩而过。—— 姚谦《品味》
