Akka远程处理-无法分配请求的地址

Question

我正在尝试Akka远程处理的示例。 每次启动远程actor系统时，都会收到此异常

details 这是我的详细信息

remoteCalculator{
  akka {
  actor {
    provider = "akka.remote.RemoteActorRefProvider"
  }
  remote {
    transport = "akka.remote.netty.NettyRemoteTransport"
    log-received-messages = on
    log-sent-messages = on
    log-remote-lifecycle-events = on
    enabled-transports = ["akka.remote.netty.tcp"]
    netty.tcp {
      hostname = "10.147.137.44"
      port = 2555
      log-received-messages = on
      log-sent-messages = on
      log-remote-lifecycle-events = on
    }
   }
  }
}

我试图通过执行以下命令来发现另一个应用程序侦听端口2555的可能性

sudo netstat -anp | grep 2555

但这并不能提供任何东西。 请帮助我找出应用程序无法在配置的地址上绑定的原因。

我找到了问题的根本原因。 实际上，这不是配置/编程问题。 我正在窗口操作系统内的虚拟主机（Ubuntu）上工作，但尚未启用网桥。 . 因此，虚拟主机无法识别 。 启用网桥后，问题得到解决。
