Network / Problem with IP

« on: September 22, 2010, 03:00:10 pm »

So, can you try the SFML network samples ? Is this working ?

No
It's working only with "127.0.0.1", not "83.145.154.170".

Have you a firewall ?
Can you modify the ports the modem let available ?

No, I don't have firewall and I don't know why it doesn't work.

I used about 30 port and nothing. They are reserved or what? How I can check free ports in my router?

When I use

Code: [Select]

IPAddress ClientAddress/ServerAddress = "83.145.154.170"; it doesn't work! It works only with:

Code: [Select]

IPAddress ClientAddress/ServerAddress;

Why?

Hello,
I've problem with server and client connection.

Server:

#include <SFML/Network.hpp>
#include <iostream>


int main()
{
    const unsigned short Port = 2435;

    sf::SocketUDP Server;
    if (!Server.Bind(Port))
    {
        std::cout << " error" << std::endl;
    }

    sf::Packet Packet;
    sf::IPAddress ClientAddress;
    unsigned short ClientPort;
    Server.Receive(Packet, ClientAddress, ClientPort);

    int a;
    Packet >> a;
    std::cout << "packet : " << a << " from "<< ClientAddress <<" port: "<< ClientPort << std::endl;

    a=12345;
    Packet.Clear();
    Packet << a;
    Server.Send(Packet, ClientAddress, ClientPort);

    std::cin.ignore(10000, '\n');
    Server.Close();
    return EXIT_SUCCESS;
}

Client:

#include <SFML/Network.hpp>
#include <iostream>


int main()
{
    const unsigned short Port = 2400;

    sf::SocketUDP Client;
    if (!Client.Bind(Port))
    {
        std::cout << " error" << std::endl;
    }

    sf::Packet Packet;
    sf::IPAddress ServerAddress;
    unsigned short ServerPort=2435;

    int a;
    a=54321;
    Packet << a;
    Client.Send(Packet, ServerAddress, ServerPort);

    Packet.Clear();
    Client.Receive(Packet, ServerAddress, ServerPort);

    Packet >> a;
    std::cout << "packet : " << a << " from "<< ServerAddress <<" port: "<< ServerPort << std::endl;

    std::cin.ignore(10000, '\n');
    Client.Close();
    return EXIT_SUCCESS;
}

When I use "IPAddress ClientAddress;" it works. But when I use:

IPAddress::GetPublicAddress();

or

IPAddress Address("83.145.154.170");

it doesn't work!

This IP is from http://whatismyip.org

The use of sockets and packets is explained in the tutorials.

I know. But I can't make "server <-> client" using UDP packets.

Hello,
I'm having problem with using  packets. Can someone makes easy server and client using UDP?

Code: [Select]


// With UDP sockets

Socket.Send(Packet, Address, Port);
Socket.Receive(Packet, Address);

Example:

       
client sends "123" to server and server receives it,
server sends "456" to client and client receives it.
