Network / Socket Selector : client crashing with 3 or more clients

« on: February 13, 2012, 04:12:08 pm »

I have a server with a socket selector and a client. They exchange data by TCP. When I run clients on the local machine (127.0.0.1, same as server) everything works fine.

However, if I run 3 or more clients from different addresses, the first client that connected crashes.

To sum things up :
Server (127.0.0.1) + Client1 (127.0.0.1) + Client2 (other ip) = OK
Server (127.0.0.1) + Client1 (127.0.0.1) + Client2 (other ip) + Client3 (other ip) = Client1 crashes

Thanks for any info regarding this.

Network / Socket Selector problem

« on: January 25, 2012, 05:24:50 pm »

I put a breakpoint on the Receive line in the server, but when I step over nothing happens. The Socket is neither Done, NotReady, Disconnected or Error. The program doesn't end either. I'm not sure what is going on...

Network / Socket Selector problem

« on: January 25, 2012, 04:25:48 pm »

I used the code on this page to make a server with sfml 2.0 : http://www.sfml-dev.org/documentation/2.0/classsf_1_1SocketSelector.php

This is where I have a problem :

Code: [Select]

// The client has sent some data, we can receive it
sf::Packet packet;
if (client.Receive(packet) == sf::Socket::Done)
{
// Extract the message and display it
std::string Message;
packet >> Message;
std::cout << "A client says : \"" << Message << "\"" << std::endl;
}

The program is stuck on the Receive method. This is the code for the client :

Code: [Select]

// Create a socket for communicating with the server
sf::TcpSocket socket;

socket.Connect("127.0.0.1", 1000);
// Send a message to the server
const char out[] = "Hi, I'm a client";
socket.Send(out, sizeof(out));

std::cout << "Message sent to the server: \"" << out << "\"" << std::endl;

// Receive an answer from the server
char buffer[1024];
std::size_t received = 0;
socket.Receive(buffer, sizeof(buffer), received);
std::cout << "The server said: " << buffer << std::endl;

I run both programs on the same computer. The client is also stuck on the Receive method.

Thanks for any help.
