如何取得局域网内网卡的物理MAC地址,或一个指定IP地址的MAC地址.谢谢了.

[hansyswin]

好象都不能解决问题, 再顶, 希望高手多多指教.谢谢

可以考虑发送arp包给局域网的所有机器

[huzhangyou]

arp协议就是用来获取对方机器的MAC地址的

可以参考一下这个

季兄,好象只能读出本机的,网内的还是读不出来.

GetMACAddress("输入IP");
成功返回 MAC Address
失败返回 0

#include <winsock2.h>
#include <stdio.h>
#include <iphlpapi.h>
#pragma comment(lib, "Iphlpapi.lib")

IPAddr ipAddr;
ULONG pulMac[2];
ULONG ulLen;

ipAddr = inet_addr(ipaddr);
memset (pulMac, 0xff, sizeof (pulMac));
ulLen = 6;

SendARP (ipAddr, 0, pulMac, &ulLen);

size_t i, j;
char * szMac = new char[ulLen*3];

if (!~pulMac[0] && !~pulMac[1]) {
return 0;
}

PBYTE pbHexMac = (PBYTE) pulMac;
for (i = 0, j = 0; i < ulLen - 1; ++i) {

}

sprintf (szMac + j, "%02X", pbHexMac[i]);

过去是用批处理执行arp来解决的,现在想之间解决它, 请给个例子,或少许详细点,谢谢了.

[huzhangyou]

You can develop it with Winpcap
And see the examples at http://www.codeproject.com/internet/winarpspoof.asp

[huzhangyou]

Packages required
To download the WinPcap Driver: http://winpcap.polito.it/
To download WinArpSpoofer: http://www.nextsecurity.net/

[huzhangyou]

Also the project on sourceforge.net
http://sourceforge.net/projects/choparp/

请各位查分,我发现今天的分有点不正常.谢谢大家!!!
