校园网H3C认证成功后，十几秒显示"No response is received from the server.."

Ubuntu下安装iNodeClient_Linux.tar.gz出现问题
----------------------
: You have passed the identity authentication
十几秒后显示
: No response is received from the server, and you will be forced to log off. Please check whether the terminal can properly access the network, or contact with the administrator.
: Disconnecting to the network...
: Connection closed.

原来英文系统用这个版本么问题，后来重装了中文的，就出现了这个问题。
----------------------
Windows系统下用iNodeSetup5.0(E0101).exe也会出现同样的问题，改回用iNodeSetup3.60-6210.exe就不会被强制下线了。旧版的iNode提示是“你的计算机可能只能访问隔离区的网络资源”，新版iNode是直接强制下线。
----------------------
不知道有没有方法解决呢？
