Qt using WOL to achieve a remote key to boot (LAN, the need for the target computer motherboard support, and plug in the network cable, with Udpsocket.writedatagram a sentence can)

Function: Let the computer shut down a key to boot, need the target computer motherboard support, and plug in the network cable;

Effect: the equivalent of manually pressing the target computer's switch button.

No technical content, simple came David ...

1. Get the target MAC address

Qbytearray smacaddr ("00-1f-16-26-d5-73");

2. Package Magic Package Chmagicpacket

Char chmacaddr[9];//should be 6 characters, but if you write 6 characters, the following sscanf_s will error, so write a large point char chmagicpacket[104]; const char *lpmacaddr=smacaddr.data (); sscanf_s (lpmacaddr, "%2x-%2x-%2x-%2x-%2x-%2x",           &chmacaddr[0],&chmacaddr[1],&chmacaddr[2],           &CHMACADDR[3],&CHMACADDR[4],&CHMACADDR[5]); memset (chmagicpacket,0xff,6); int packetsize=6; for (int i=0;i<16;i++) {     memcpy (chmagicpacket+packetsize,chmacaddr,6);        packetsize+=6; }

3. Send a magic Packet

Udpsocket.writedatagram (Chmagicpacket, 102, qhostaddress ("255.255.255.255"), 50209);
