如何监听无线设备请求的套接字？ [英] How to listen socket requested from wireless device?

问题描述

作为标题。

As title.

private void StartServerToListen()
{
    try
    {
        ServerPort = 1001;
        IPEndPoint ServerIPEndPoint = new IPEndPoint(IPAddress.Any, ServerPort);
        ServerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        ServerSocket.Bind(ServerIPEndPoint);
        ServerSocket.SetSocketOption(SocketOptionLevel.Tcp, SocketOptionName.AcceptConnection, true);
        //ServerSocket.SetSocketOption(SocketOptionLevel.Tcp,SocketOptionName.
        ServerSocket.Listen(32767);
        ServerSocket.BeginAccept(new AsyncCallback(ServerBeginAccept), ServerSocket);
    }
    catch (SocketException se)
    {
        LogAccess.WriteSocketException(ref se, DateTime.Now);
    }
    catch (Exception ex)
    {
        LogAccess.WriteException(ref ex);
    }
}

这是我如何从以太网开始监听套接字的子程序。它在以太网内部（有线）很好用，但是我无法接受来自无线设备的任何套接字连接。请教我一下我应该改变接受soc来自无线设备的连接。并且，我确保服务器端和客户端连接到同一个AP，在同一子网掩码中，IP为192.168.x。*

This is the subroutine that how I start to listen socket from Ethernet. It works well inside the Ethernet (with wire ) but I can't accept any socket connection from wireless device. Please teach me what should I change to accept socket connection from wireless device. And, I ensure that the server side and client side are connected to same AP, in the same subnet mask, IPs are 192.168.x.*

推荐答案

它不应该无论设备是有线还是无线，只要它们连接到同一个子网（相同的IP地址范围和网络掩码），并且它们在相同的端口号上运行/侦听。



如果设备未配置/连接到同一子网，则需要通过UDP进行广播或多播以查找和通信。

It should not matter whether the device is wired or wireless as long as they are connected to the same subnet (same IP address range and netmask) and they are running/listening on the same port number.

If the device is not configured/connected to same subnet you would need broadcasting or multi-casting via UDP to find and communicate.
