如何取得客户端网卡MAC地址？谢谢！

[baker_gw]

我想是不是有权限问题，可能直接使用asp.net无法实现，是否需要做一个activeX程序，写activeX我又不太懂。
我还有一个想法：
1.asp.net能取得客户机IP地址
2.server里可以通过命令行nbtstat -a IP取得ip对应的网卡的IP地址
把以上两个结合起来，最终取得客户机的mac
可行吗
最主要的问题是服务端运行的asp.net程序如何执行命令行并取得结果值
从中找出mac地址
谢谢

string sendip=Request.ServerVariables["REMOTE_ADDR"].ToString(); //取得用户IP

好像直接用命令是不能实现的

用asp.net取不到的

[huangsuipeng]

IP是可以的，但是MAC地址就应该不行了，况且如果不是使用802。3的话，根本不会用到MAC，

[bestytlds]

只有在局域网中，才能取到MAC地址。

server里可以通过命令行nbtstat -a IP取得ip对应的网卡的IP地址

我相信你用nbtstat是ping不到我的机器的，我上网是通过了n层代理，就连IP你也取不到吧。

用WMI应该可以

WMI的WIN32_NETWORKADAPTERCONFIGRATION

[huangsuipeng]

获取网卡硬件地址
using System.Management;
...
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach(ManagementObject mo in moc)
{
if((bool)mo["IPEnabled"] == true)
Console.WriteLine("MAC address\t{0}", mo["MacAddress"].ToString());
mo.Dispose();
}
}

using System.Management;
...
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();

foreach(ManagementObject mo in moc)
{
if((bool)mo["IPEnabled"] == true)
Console.WriteLine("MAC address\t{0}", mo["MacAddress"].ToString());
mo.Dispose();
}
}

看一个帖子：

Because of the way that the internet was designed and the way that the IP protocol works, you wouldn't be able to find a mac address of someone unless you were local to them. The post earlier about using ping and arp is correct. The mac address is put into the IP packet at the 2nd level of the OSI model, its a physical address... once you go out through a router the mac address of the reported packet is changed, and is changed each and every time.. think of the mac as a "Return" address. You send out a packet and it goes across the country, and goes through 5 routers, the mac address on the packet will change each and every time it goes through a router, where the IP address won't. It's a type of routing code that the routers use to identify where the packet came from and where to send a response to.

example

Machine A sends a packet to Machine B, and it passes through Firewall C and D. The packet does this:

Machine A sends the packet to firewall C, firwall C repackages the packet with its mac address and looks for the quickest route to machine B, it determines that firewall D is the closest to it, so it repackages the packet with its own mac address (since that is where D will send a response to if it cant get to machine B) and sends it on to D.. D does the exact same thing and sends the packet to B. Once Machine B receives the packet the entire process starts over again, the last mac address that is reported is for firewall D, but the IP points to Machine A, thats how it knows where to go.

webdiyer说的都是 基于广域网的！ 楼主如果是在互联网上应用的话 获取mac 是不可行的

[ahui_net]

路由是不转发客户的mac的

各位同志
我就是在局域网内取MAC
是为了控制系统安全
要获取登陆方的MAC地址
