Question

嘿伙计们，我一直试图制作一个简单的控制台应用程序来查看我的网络流量：P我试图只是阅读它。

无论如何我从WSAIoctl函数得到一个错误，错误代码WSAGetLastError给我的是10022，MSDN告诉我它与此相关：

无效的参数。提供了一些无效参数（例如，为setsockopt函数指定了无效级别）。在某些情况下，它还引用套接字的当前状态 - 例如，在未侦听的套接字上调用accept。

我试过没有运气搞乱这些争论：/请帮助我：P

这是我的代码：

WSADATA wsaData;
int startup = WSAStartup(0x0202, &wsaData);

if(startup != 0) {
    cout << "Error: could not initalize WSADATA for target socket." << endl;
    system("pause");
}

unsigned long BytesReturned;
int InBuffer, OutBuffer, LPCVoid;
int optValue = 1;
SOCKET sock = socket(AF_INET, SOCK_RAW, IPPROTO_IP);

Sleep(await);
cout << "creating and configuring RAW_SOCK" << endl;

int listening = listen(sock, SOMAXCONN); // tried debugging using this.
int sockopt = setsockopt(sock, IPPROTO_IP, 2, (char*)&optValue, sizeof(optValue));
int SockMode = WSAIoctl(sock, SIO_RCVALL, &InBuffer, sizeof(InBuffer), &OutBuffer, sizeof(OutBuffer), &BytesReturned, NULL, NULL);
//0x98000001
if(SockMode == 0) {
    Sleep(await);
    cout << "RAW_SOCKET created successfully!" << endl << "Trying to listen for incoming network packets..." << endl;
    int listeningk = listen(sock, SOMAXCONN);

    if(listening == 0) {
        Sleep(await);
        cout << "socket listening without problems, looking for incoming request..." << endl;
    }
    else {
        Sleep(await);
        cout << "Error: could not listen on socket." << endl;
        exit(EXIT_FAILURE);
    }
}
else {
    Sleep(await);
    cout << "Error: could not create RAW_SOCKET..." << endl << "Dumping SockMode!\r\nint SockMode = " << SockMode << endl;
    cout << "setsockopt = " << sockopt << endl; 
    cout << "WSAGetLastError: " << WSAGetLastError() << endl;
    system("pause");
}

在收听之前，您的套接字需要绑定。此外，对于此WSAIoctl选项，您必须遵守（来自MSDN docs）：

套接字也必须绑定到显式本地IPv4或IPv6 interface，表示您无法绑定到INADDR_ANY或 IN6ADDR_ANY。

我建议在尝试推进此代码之前先进行一些基本的自我教育。有一些常见操作的代码示例，如MSDN中的套接字设置。
