Deal with winsock and UDP. Write on one PC, no LAN. On the client send a broadcast request: sockaddr_in broadcast; // enable broadcasts int enableBroadcast = 1; setsockopt(ClientSocket, SOL_SOCKET, SO_BROADCAST, (char*)&enableBroadcast, sizeof(enableBroadcast)); broadcast.sin_family was = AF_INET; broadcast.sin_port =...

There is a server on the PC, then start the client (All UDP). How to make a network broadcast to find the server to get its ip (well, there is 127.0.0.1 and in any case I think) and the port to fill the structure : RecvAddr.sin_family was = AF_INET; RecvAddr.sin_port = htons(Port); RecvAddr.sin_addr.s_addr = inet_addr("127....

The fact that after some undefined time the phone loses the network, although they were included (that is, power available for PoE is), not pre...

Hi all! Need an alternative to ssh which was working on udp

There are 2 bit fields are combined into one structure. Previously, when the total structure size allowed, did the Union via union in a uint64. Now the size of the structures was more give in the QByteArray from the server to the client and now there is a problem with the reception and analysis. How do normal people? you c...

You need to write tcp/udp server-client for macos and ios, with the help of some tools you can implement it? would be cool if more references, and video tutorials will be found on this topic)

You need to send the saved web page to the client: Try to split and upload the file in parts: Server:private static void SendFile() { // Create a file stream and translate it into bytes Byte[] bytes = new Byte[UdpFileServer.fs.Length]; Console.WriteLine("Sending file size" + UdpFileServer.fs.Length + "bytes"); UdpFil...
