通过SSH端口转发连接到Zookeeper

Question

我可以在本地连接到我的Zookeeper实例：

[zookeeperServer] #zkCli.sh -server 127.0.0.1:2181

但是，如果我尝试通过SSH转发端口进行操作，它最初会连接，但会立即断开连接：

[myLaptop] #ssh -L 1234：127.0.0.1：2181 zookeeperServer

[myLaptop] #zkCli.sh -server 127.0.0.1:1234

2014-10-03 15:25:18,989 [myid:] - INFO  [main-SendThread(127.0.0.1:1234):ClientCnxn$SendThread@852] - Socket connection established to 127.0.0.1/127.0.0.1:1234, initiating session

..... 前3行（打开套接字，已建立套接字连接，无法读取其他数据）开始重复 .....

还有什么其他的（一些主机名等）Zookeeper依赖，需要配置以便与Zookeeper的连接在转发端口上工作？
