can't produce to kafka with a remote standalone zookeeper

Guys,
it can work if i use kafka server (0.8) and zookeeper (3.4.5) in same machine (centos 6.3 final), but failed by seperating them into two machines.
1, when trying to produce, find some error messages,
2,, try to consume, failed because " WARN [console-consumer-65386_server3-1390013879485-3f815f14], no brokers found when trying to rebalance. (kafka.consumer.ZookeeperConsumerConnector)"
But the topic is created successfully in kafka datadir.
I have logged details in github issue 48 (https://github.com/kafka-dev/kafka/issues/48)

please help me

Thanks
