怎样在获得和设置mac 地址呢？？

[guaiwei]

请教各位大侠怎样编程才能获得和设置mac地址？小弟先谢过了

[pacman2000]

在linux下获得需要用ioctl调用，更改好像没办法的吧。。。

[qiaoerfu]

铅入式系统应该是可以改的
正在研究．．．．．．
嘿嘿！

system("ipcopnfig /all");
投機取巧

MAC地址是固化在网卡的flashrom里的，不可能更改。只能通过spoof方式改变与Ip的对应关系。

如果是设置mac地址，搜索windows的registry注册库，找到所有的Mac地址，一个一个该，看哪个能行。

MAC地址也是可以更改的

论坛里有mac地址的总结，可以去看看

环境:w2k server + vc6.0 说明：这里只能获得MAC地址。
#include <stdio.h>
#include <stdlib.h>
#include <httpext.h>
#include <windef.h>
#include <Nb30.h>
int getMAC(char * mac)
{
NCB ncb;
typedef struct _ASTAT_
{
ADAPTER_STATUS adapt;
NAME_BUFFER NameBuff [30];
} ASTAT, * PASTAT;
ASTAT Adapter;

typedef struct _LANA_ENUM
{ // le
UCHAR length;
UCHAR lana[MAX_LANA];
} LANA_ENUM ;
LANA_ENUM lana_enum;

UCHAR uRetCode;
memset( &ncb, 0, sizeof(ncb) );
memset( &lana_enum, 0, sizeof(lana_enum));

ncb.ncb_command = NCBENUM;
ncb.ncb_buffer = (unsigned char *) &lana_enum;
ncb.ncb_length = sizeof(LANA_ENUM);
uRetCode = Netbios( &ncb );
if( uRetCode != NRC_GOODRET )
return uRetCode ;

for( int lana=0; lana<lana_enum.length; lana++ )
{
ncb.ncb_command = NCBRESET;
ncb.ncb_lana_num = lana_enum.lana[lana];
uRetCode = Netbios( &ncb );
if( uRetCode == NRC_GOODRET )
break ;
}
if( uRetCode != NRC_GOODRET )
return uRetCode;

memset( &ncb, 0, sizeof(ncb) );
ncb.ncb_command = NCBASTAT;
ncb.ncb_lana_num = lana_enum.lana[0];
strcpy( (char* )ncb.ncb_callname, "*" );
ncb.ncb_buffer = (unsigned char *) &Adapter;
ncb.ncb_length = sizeof(Adapter);
uRetCode = Netbios( &ncb );
if( uRetCode != NRC_GOODRET )
return uRetCode ;
sprintf(mac,"%02X-%02X-%02X-%02X-%02X-%02X",
Adapter.adapt.adapter_address[0],
Adapter.adapt.adapter_address[1],
Adapter.adapt.adapter_address[2],
Adapter.adapt.adapter_address[3],
Adapter.adapt.adapter_address[4],
Adapter.adapt.adapter_address[5]
);
return 0;
}
int main(int argc,char* argv[])
{
char mac[200];
getMAC(mac);
printf(" mac : %s \n",mac);
return 0;
}

运行结果：
D:\work\mac\Debug>m
mac : 00-0A-EB-50-89-C2

D:\work\mac\Debug>ipconfig /all
