检测MAC地址？ - 通过浏览器，没有一个插件 [英] Detect MAC Addresses? - via browser, without a plugin

问题描述

有关验证目的，有没有一种方式，他们在网页上注册，例如检测用户的MAC地址？我想preFER一个LAMP的方法，但也开到ASP.NET的可能性。

For validation purposes, is there a way to detect a user's mac address as they're signing up on a webpage, for example? I'd prefer a LAMP approach, but also open to ASP.NET possibilities.

推荐答案

我想你可以通过阅读 ARP缓存底层操作系统，假定客户机和服务器在同一个网络上。

I guess you could by reading the ARP cache of the underlying OS, assuming that the client and server are on the same network.

然而，使用的MAC地址验证是在大多数情况下的馊主意

However, using the MAC address for validation is under most circumstances a bad idea:

• MAC地址可以很容易地欺骗。许多网络驱动程序允许您设置地址到任何你想要的。

• The MAC address can be easily spoofed. Many network drivers allow you to set the address to whatever you want.

MAC地址是链路本地。如果在服务器和客户端之间的至少一个路由器，服务器将看到最近的路由器的MAC地址

The MAC address is link local. If there is at least one router between the server and the client, the server will see the closest routers MAC address.
