配置FEDORA13网络时出现如下问题
ERROR : Connection activiation failed :Device not managed by NetworkManager
解决:http://www.cnblogs.com/google4y/archive/2011/07/13/2105546.html
you have problem because both of NetworkManager and network using same Network driver and default network blocking access for NetworkManager. if you disable NetworkManager your problem will disappeared after restart.
这句话我翻译一下:
你出现问题是因为NetworkManager 和 network 使用的是同样的网络驱动,默认使用network,理所当然就要阻塞NetwrokManager了。
如果你把NetwrokManager关掉,那么重启系统后, 你的问题就会消失了。
