Question

我在thrift中创建了一个服务器和一个客户端。然后我在计算机上启动了thrift服务器。我使用我的机器IP地址在局域网中的另一台计算机上运行客户端。

public class ArithmeticClient {

private void invoke() {
    TTransport transport;
    try {
        transport = new TSocket("192.168.0.232"/*this is my machine,which the sever runs' IP address*/, 7911);

        TProtocol protocol = new TBinaryProtocol(transport);

        ArithmeticService.Client client = new ArithmeticService.Client(protocol);
        transport.open();

        long addResult = client.add(100, 200);
        System.out.println("Add result: " + addResult);
        long multiplyResult = client.multiply(20, 40);
        System.out.println("Multiply result: " + multiplyResult);

        transport.close();
    } catch (TTransportException e) {
        e.printStackTrace();
    } catch (TException e) {
        e.printStackTrace();
    }
}

public static void main(String[] args) {
    ArithmeticClient c = new ArithmeticClient();
    c.invoke();
}

}

我收到了错误

我该如何解决这个问题。

两台电脑都运行Fedora。版本不同（17和19）

the docs说的是什么，以及我猜的是什么。这可能是原因吗？如果您尝试ping或telnet该计算机会发生什么？
