我正在使用 RMI 客户端，但是当我尝试从除 localhost 之外的任何机器连接到它时，它会收到拒绝的连接堆栈跟踪。我确认我的防火墙已关闭。我还需要做什么？这是我的代码

public class FrontManagerClient {

    boolean state;
    String command;
    String value;

    public FrontManagerClient(String cmd,String value) {
        this.command=cmd;
        this.value=value;
    }

    public  boolean getCommand() throws RemoteException, NotBoundException, MalformedURLException{

        FrontPanelManagerIntrface f=(FrontPanelManagerIntrface)Naming.lookup("lookup=//localhost//frontPanelRequestControllerService");
        state=f.Communicate(command, value);
        return state;
    }

    public static void main(String[] args) throws RemoteException, NotBoundException, MalformedURLException {
        FrontManagerClient f = new FrontManagerClient("Password_Enter", "admin");
        System.out.println(""+f.getCommand());
    }
}

当我运行服务器并运行客户端时，它会显示此错误消息

主机 10.96.28.6 上没有运行 RMI 注册表，或者您没有修复防火墙。
