server/client not working on ubuntu16.04

[truewq]

Hi @minhanghuang
I built the cyberRT on ubuntu16.04. I did the server/client test, but it's not working. Do you have any suggestion?

The ./cyber/examples/cyber_example_server does not receive request from ./cyber/examples/cyber_example_cilent

I checked the service and node, seems client_node status is wrong.

Hi 大佬黄
我测试server/client时，发现client与server的通信异常。用cyber_xx脚本检查，发现client的节点信息查不到。请教一下定位问题的建议思路。

Hi @truewq 会不会是test@test-desktop:/xxxxx/cyberRT/CyberRT/build$ cyber_node info client node 中间遗漏_的造成的? 我不确定你当时出入的命令 可以试试cyber_node info client_node查看节点信息

HI @minhanghuang

确实是拼写错误，cyber_node可以正常显示：

但是，cilent与server之间的通信还是异常的……

需要配一下日志的路径, 你可以把example里的AINFO改成std::cout
