同Winsock1相比,最明显的就是支持了Raw Socket套接字类型,通过原始套接字,我们可以更加自如地控制Windows下的多种协议,而且能够对网络底层的传输机制进行控制。 1、创建一个原始套接字,并设置IP头选项。 SOCKET sock; sock = socket(AF_INET,SOCK_RAW,IPPROTO_IP); 或者: s = WSASoccket(AF_INET,SOCK_RAW,...
使用raw socket,包的包头部分由我们自己实现,操作系统只负责把数据原本发出去,它不会在上面添加修改任何东西,比如其他“包头” The Unix operating system has raw socket support since ancient times. But the problem is with Windows. None of Windows 95, 98, 98SE supported raw sockets. Raw sockets became...

可以用它来发送和接收 IP 层以上的原始数据包, 如 ICMP, TCP, UDP...int sockRaw = socket(AF_INET, SOCK_RAW, IPPROTO_RAW);这样我们就创建了一个 Raw Socket Sniffer: 嗅探器 关于嗅探器的原理我想大多数人可能都知道 1. 把网卡置于混杂模式;2. 捕获数据包;3. 分析数据包.但具体的实现知...

raw-socket-sniffer.exe 127.0.0.1 capture.cap Replace127.0.0.1with an IP address from the network interface for which packets should be captured, and the filecapture.capwith the name of the file to which to write packets. If the Windows Firewall is enabled it will likely require an update to...
SOCKET_SECURITY_PROTOCOL Indicates the type of security protocol to be used on a socket to secure network traffic. SOCKET_USAGE_TYPE Used to specified the usage type for the socket. TCPSTATE Indicates the possible states of a Transmission Control Protocol (TCP) connection. WSAECOMPARATOR The Wind...
This socket type uses the User Datagram Protocol (UDP) for the Internet address family (AF_INET or AF_INET6). SOCK_RAW 3 A socket type that provides a raw socket that allows an application to manipulate the next upper-layer protocol header. To manipulate the IPv4 header, the IP_HDRINCL ...
FWP_CONDITION_FLAG_IS_RAW_ENDPOINT(表示原始端點的旗標) 0x00000010 表示傳送和接收流量的本機端點是原始端點。 此旗標適用於下列篩選層: FWPM_LAYER_INBOUND_TRANSPORT_V4 FWPM_LAYER_INBOUND_TRANSPORT_V6 FWPM_LAYER_INBOUND_TRANSPORT_V4_DISCARD (入站傳輸V4丟棄層) ...
