用了nutzmore里面的dubbo插件在本地测试环境已经完全可以运行了，但是用了远程的服务器之后就报出了下面的问题，远程服务器的端口和zookeeper都正常运行着，端口也开了可以telnet得通

zookeeper在哪个服务器上？看上去是连不上zookeeper所在的服务器哦

@wendal 但是我本地另外一个dubbox工程直接就连上了。。。

@chafferer 你本地能连，跟该服务器是否能连，有什么关联性呢？他们处于同一个内网？在该服务器上能telnet通zookeeper服务器？

@wendal 我本地有两个工程，一个是dubbox的工程，一个是nutz-dubbo的，然后dubbox那个可以连得上服务器，nutz-dubbo连不上，所以我很困惑啊。telnet没问题。我在想是不是timeout时间太短

都是写ip吗？有时候dns也会卡壳

@wendal 恩，都是ip。 看来是网络不咋地，timeout写了20000，成功连上了~ 不好意思兽总

... 网络那么差
