NetProg - Raw RAW Socket Raw Sockets | What  A raw socket allows direct access to lower-level networking protocols, bypassing some of the abstractions provided by standard socket APIs.  Requirements:  Administrative privilege  Key Features:  Direct manipulation of IP headers and payloads.  Useful for custom protocols or advanced network diagnostics. Use Cases  Custom Protocol Implementation  Packet Manipulation  Build diagnostics and monitoring tools like packet sniffers or ping utilities  Simulate specific traffic patterns or attack scenarios Raw Socket  Setup the socket (Chose which ProtocolType you are interested in): Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Raw, ProtocolType.IP);  Bind the socket s.Bind(new IPEndPoint(IPAddress.Parse("192.168.8.138"), 0));  If you want to allow the application to provides the IP header for outgoing datagrams. s.SetSocketOption(SocketOptionLevel.IP, SocketOptionName.HeaderIncluded, true);  Set socket to promiscuous mode byte[] optionIn = new byte { 1, 0, 0, 0 }; s.IOControl(IOControlCode.ReceiveAll, optionIn, null);  Start Receiving and parsing Raw Socket Privilege Error
