Network / TCP doesn't work on remote computer

« on: June 11, 2021, 09:19:43 pm »

I created a simple application that sends a string to another machine. It works fine with both the client and the server connected to the same network, but it doesn't connect to a public address. Wireshark shows that the server is not responding if I send a request to the remote computer.

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

int main()
{
        sf::Packet packet;
        char who;
        std::cout << "Are you a server (s) or a client (c)?" << std::endl;
        std::cin >> who;
        if (who == 's')
        {
                sf::TcpSocket client;
                std::cout << "Public: " << sf::IpAddress::getPublicAddress() << std::endl;
                std::cout << "Local: " << sf::IpAddress::getLocalAddress() << std::endl;
                sf::TcpListener listener;
                if (listener.listen(3005) != sf::Socket::Done)
                        std::cout << "Could not bind port" << std::endl;
                if (listener.accept(client) != sf::Socket::Done)
                        std::cout << "Could not connect to client" << std::endl;
                client.receive(packet);
                std::string name;
                packet >> name;
                std::cout << name << std::endl;
        }
        else if (who == 'c')
        {
                sf::TcpSocket server;
                sf::IpAddress ip;
                std::cin >> ip;
                if (server.connect(ip, 3005) != sf::Socket::Done)
                        std::cout << "Could not connect to server" << std::endl;
                packet << "Some random text";
                server.send(packet);
                std::cout << "Packet was sent" << std::endl;
        }
        system("pause");
}

Oh, I fixed that. Just installed older version of MinGW

That's the call stack

placing sfml-system after the sfml-network didn't help
using binary didn't help either

Network / ftp.download crash

« on: September 26, 2020, 11:10:12 am »

Tied using this one (ftp.download( "test.txt", "", Ftp::Ascii); ), but my app crashes with windows sending data error. Other functions work properly: I connected to server, changed directory, it even shows me a directory list, and there is a test.txt in it. MinGW isn't showing any errors and compiles the app as always. Changing transfer mode didn't help.

This surprisingly does nothing. The same error.
Ftp::Response x = ftp.download("test.txt", "");
cout << "FTP Download: " << x.getStatus() << " : " << x.getMessage() << "\n";

Using windows 10 and MinGW. Compiling with this:
g++ main.cpp -o main.exe -ID:\\SFML-2.5.1\\include -LD:\\SFML-2.5.1\\lib -lsfml-graphics -lsfml-window -lsfml-system -lsfml-network
