Hi TTT
Welcome to the forum.

... but seems it donest support raw socket. ...

I don't know why you would think that. This is how I set up a raw socket:

Code: [Select]

/******************************************************************/
/* Configures the socket for the Sniffer routine */
static void SetupRawSockets(void)
{
sniffersock=socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL));
fcntl(sniffersock, F_SETFL, fcntl(sniffersock, F_GETFL) | O_NONBLOCK);
return;
}
/******************************************************************/sniffersock is defined as an int.

You can find the source code it came from here:

Hi TTT

thanks so much. ...

You are welcome.

If you are new to network programming, this is worth checking out. It doesn't cover raw sockets, but it's easy to understand and
covers important concepts. It also has coding samples:

Raw sockets means you will likely be packing data structures. This large site covers many protocols and the data layout of
their respective packets:
