hi everybody, i have an issue with my asio-client that wants to connect to an asio-server. when i set my server on a machine in our network to listening on a port (>1024) and then try to connect with my client via this port, i get a "Connection refused"-exception. this happens every time the server and client are located on different machines. if i try this on the same machine it works fine! also, if i try to connect via telnet from another machine it works! here's the client-setup-code snippet, maybe i missed a special config there?: tcp::resolver resolver( _io ); //_io is class-member tcp::resolver::query query( server, port ); //server and port are char-buffers tcp::resolver::iterator iter = resolver.resolve( query ); _socket = new tcp::socket( _io ); tcp::resolver::iterator end; // End marker. boost::system::error_code error = error::host_not_found; while (error && iter != end) { _socket->close(); _socket->connect(*iter++, error); } if (error) throw boost::system::system_error( error ); } catch( std::exception& e ) { cout << "NetClient Konstruktor: " << e.what() << endl; }
