Due to some other conflicts, I disabled/stopped NetworkManager in Fedora 15,
Now, for network configuration I used system-config-network-gui to config & enable Ethernet interface,
Problem is, when system starts, the Ethernet does not become enabled. Although in configuration through system-config-network, I specifically checked "Activate device when computer starts" "Allow all users to enable and disable the device",
and cleared "Controlled by NetworkManager"
I double checked the config file "/etc/sysconfig/networking/devices/ifcfg-eth0" to see if the configurations are saved correctly and onboot is enabled. And they look OK.
so, Why still it does not become enabled automatically on boot?
