我正在尝试设置一个kafka集群，其中有一个zookeeper示例运行在与kafka服务器不同的计算机上。
我可以从同一台计算机连接到zookeeper示例（通过在该计算机上创建kafka服务器），但无法从本地网络中的计算机连接其他kafka服务器。
所有服务器都运行在私有云中，默认情况下所有端口都是打开的。我可以ping和telnet到机器，但我似乎无法访问zookeeper示例：

# On the ZooKeeper machine

> telnet 10.155.208.82 2181
Trying 10.155.208.82...
Connected to 10.155.208.82.

# On any other machine

> telnet 10.155.208.82 22
Trying 10.155.208.82...
Connected to 10.155.208.82.

> telnet 10.155.208.82 2181
Trying 10.155.208.82...

# Nothing happens ...

Kafka在超过连接zookeeper的超时时间后出错： [2015-12-28 18:52:21,632] INFO Initiating client connection, connectString=10.155.208.82:2181 sessionTimeout=6000 watcher=org.I0Itec.zkclient.ZkClient@43ee72e6 (org.apache.zookeeper.ZooKeeper) [2015-12-28 18:52:21,645] INFO Opening socket connection to server 10.155.208.82/10.155.208.82:2181.
