I am wondering if this is possible, or I can not perform such manual manipulation of sockets? If so, how can I try? I'm not trying to make this old DoS attack, just curious how to send it through C #. Thanks
You must do this by creating a socket using the SocketType.Rawand parameters ProtocolType.IP.
SocketType.Raw
ProtocolType.IP
You can then write the bytes that form the SYN packet to the socket.
