网络唤醒程序代码

发布时间：2005-01-06 11:15:20

I 根据网络唤醒数据包编写的网络唤醒程序，只实现了基本的代码部分，还不能发送密码。
for linux 的，要有LIBNET库的支持哦。

#include <unistd.h>
#include <stdio.h>
#include <libnet.h>
main()
{

u_char *packet;
u_short packet_size=0;
u_char enet_dst[6]={0x00,0x11,0x22,0x33,0x44,0x55};
u_char enet_src[6]={0x00,0x40,0x05,0x47,0x23,0xfb};
u_char *payload;
int payload_size=0;
char *dev="eth0";
char ebuf[LIBNET_ERRBUF_SIZE];
struct libnet_link_int *s;
int i,c;

payload=(u_char *)malloc(102);

packet_size=LIBNET_ETH_H+102;

if((libnet_init_packet(packet_size,&packet))==-1)
{ }
if((s=libnet_open_link_interface(dev,ebuf))==NULL)
{ }

memset(payload,0xff,6);
payload_size+=6;

for(i=0;i<16;i++){
memcpy(payload+payload_size,enet_dst,6);
payload_size+=6;
}

libnet_build_ethernet(enet_dst,
enet_src,
0x842,
payload,
payload_size,
packet);
for(i=0;i<packet_size;i++)
printf("%2.2x ",packet[i]);

c=libnet_write_link_layer(s,dev,packet,packet_size);

printf("/nsend size is: %d",c);
libnet_destroy_packet(&packet);
}

//IPAddress: 除去网络号后的IP段全部补255 ,如 210.45.234.255
// MacAddress : 6个字节的字符型数组，每块网卡都有一个物理地址，在Window98中可以用
// winipcfg.exe 查询出来。

void TWakeUpOnLanForm:: WakeRemoteComputer(AnsiString IPAddress,unsigned char * MacAddress)
{
        unsigned char SendBuf[102];
        for( int i = 0; i < 102; i ++)
        {
                SendBuf[i] = (i < 6) ? 0xFF : MacAddress[i%6];
        }
        TMemoryStream * MemoryStream = new TMemoryStream();

        MemoryStream -> Clear();
