you could try this private void SendToServer(IPAddress IP, int Port) { try { TcpClient tcpclnt = new TcpClient(); tcpclnt.Connect(IP, Port); //your code here } UPDATE For the server you’ll use this public static void Main() { TcpListener serverSocket = new TcpListener(9999); TcpClient clientSocket = default(TcpClient); int counter = 0; serverSocket.Start(); Console.WriteLine(” >> ” + “Server … Read more
That is a unique feature of web page access and can’t be used with regular sockets. It can be used with servlets, though, because they are basically web pages. Edit: Now that the question has been revised, I can now answer the underlying question much better than the original question. It is not a good … Read more
t=”POST / HTTP/1.0\r\nAuthentication: Bot {token}\r\nHost: discord.com/api/guilds/{702627382091186318}/channels\r\n\r\n” This is not a valid HTTP request. You essentially send (line breaks added for clarity): POST / HTTP/1.0\r\n Authentication: Bot {token}\r\n Host: discord.com/api/guilds/{702627382091186318}/channels\r\n \r\n But a correct POST request would look like this instead: POST /api/guilds/{702627382091186318}/channels HTTP/1.0\r\n Authentication: Bot {token}\r\n Host: discord.com\r\n Content-length: … \r\n <body, where size matches … Read more
I’m guessing you use TCP? Then you have to remember that TCP is a streaming protocol, without message boundaries and without any start or end (except connection established and closed). A single recv call may receive less or more than what was sent in a single send call. You need to come up with a … Read more
Introduction TCP is a reliable, connection-oriented protocol used for communication between two hosts over a network. It is one of the most commonly used protocols in computer networks. The Transmission Control Protocol (TCP) is responsible for ensuring that data is sent and received in the correct order. This article will discuss the order in which … Read more
If server and client are on the same network, you will have to use ARP. This protocol is designed to get the MAC address to a given IP address. As soon as there is something like a router between client and server, ARP will only reveal the MAC address of the router since this is … Read more
Well…no, there wouldn’t be, ServerSockets don’t have streamed input/output. A ServerSocket accepts connections, creating a Socket for each connection received (see accept), which is where the streams for that connection are. solved Where is the getInputStream() function in java 1.8?
listenfd = lacz_tcp(wiadomosc->port); From what I can tell, the port has not been initialized before you call bind. Log the port to be sure that the server is listening on the correct port. 2 solved Connection refused – tcp socket in linux [closed]
in short, you have 3 main options: open a thread per client, that spawns after you accept(), and the run a loop in this context, that does read() => …. => write() run a main loop that uses select() on clients after accept() for each, and handle dispatching yourself. best option – use an async … Read more
while(true) is an infinite loop, the only way of getting out of it is using break. Or changing while(true) to some condition that alternatively ends. In this code, the while(true) part makes no real sense to me, you should probably add something else to that part as well, e.g. some connection stuff etc. 6 solved … Read more
since I don’t have response for my question. I would like to share with you the response for that problem. The acsd service take the port because the socket is not closed and the option SO_REUSEADDR is set solved My linux application port is taken by another service when it’s stopped
In your server code the read() should use the socket descriptor returned from the accept() not from the call to socket(). So try reading using newSocket rather than welcomeSocket. n = read(newSocket,buffer,255); 1 solved Server Client program in C using sockets and tcp
There are multiple ways to approach this problem (REST, WebSocket, etc.) I recommend using sockets in this case but I’ll leave it up to you to read up on the pros/cons of different approaches. Socket.IO has a popular Android library for real-time bidirectional event-based communication between two nodes. At a high level, to use Socket.IO … Read more
Introduction Sharing text and numbers over the internet can be a daunting task, especially when it comes to developing a client-side application. Fortunately, there are a few simple solutions that can help you quickly and easily share text and numbers over the internet. In this article, we will discuss how to create a simple sharing … Read more
Simple: int my_int = 1234; send(socket, &my_int, sizeof(my_int), 0); The above code sends the integer as is over the socket. To receive it on the other side: int my_int; recv(socket, &my_int, sizeof(my_int), 0); However, be careful if the two programs runs on systems with different byte order. Edit: If you worry about platform compatibilities, byte … Read more
