WebDESCRIPTION top. Raw sockets allow new IPv4 protocols to be implemented in user space. A raw socket receives or sends the raw datagram not including link level headers. The IPv4 layer generates an IP header when sending a packet unless the IP_HDRINCL socket option is enabled on the socket. When it is enabled, the packet must contain an IP header. WebThe header consists of a 32-bit Message ID, 32-bit Length Field, 32-bit Request ID/Session ID, 8-bit Protocol Version/8-bit Interface Version/8-bit Message Type/8-bit Return Code.
