scala - akka actor 远程启动，但无法远程登录

Question

从下面的运行日志中，它说远程启动正常并监听 2552 端口：

[INFO] [08/16/2014 21:05:57.523] [run-main-0] [Remoting] Starting remoting
[INFO] [08/16/2014 21:05:57.692] [run-main-0] [Remoting] Remoting started; listening on addresses :[akka.tcp://HelloRemoteSystem@127.0.1.1:2552]
[INFO] [08/16/2014 21:05:57.694] [run-main-0] [Remoting] Remoting now listens on addresses: [akka.tcp://HelloRemoteSystem@127.0.1.1:2552]

但是telnet那个端口失败了。这是否意味着无法使用 telnet 验证远程，或者
远程处理有问题？正在尝试 127.0.0.1... telnet：无法连接到远程主机：连接被拒绝
