Can not assign requested address / Unable to set static ip

Fedora uses two different methods to control network cards. 1) Network Manager. 2) Network Configurations.

By default fedora uses Network Manager. But the disadvantage of using Network Manager is that we can not use static ip address.

So in order to use we need to stop/disable Network Manager, for this follow the command

>To Stop

service NetworkManager stop 

>To Disable permanently 

chkconfig NetworkManager off

Now restart you network as follows

service network restart

To start network with every boot

chkconfig network on
