Unhappy Network not activting on boot


I installed Fedora 12 on a couple of boxes that are to become headless monitoring stations. When I reboot them, I still have to go in via the console to activate the network device (eth0). I have the box checked to activate on boot. I even went and looked in ifcfg-eth0 and ONBOOT is set to "yes". I've worked with earlier versions of Fedora and I also have Redhat 5 installations, and networking always comes up when the system are booted. Also, in various directories under /etc/sysconfig/networking, I found three additional copies of ifcfg-eth0 and they all agree, "ONBOOT=yes".

Any ideas?

Re: Network not activting on boot

I am pretty sure that in F12 NetworkManager is/was the default "network manager". If you are configuring your eth0 network device using system-config-network (netowrk), then you would need for "network" to be your active network service and have the "NetworkManager" service disabled.

Also, in the eth0 setup, there is the option "controlled by nm=", which if you are using the "network" service should be set to "no". If you are using the "network" service and not "NetworkManager", and that is set to "yes", then network will ignore eth0 at bootup, as it has been told the "other guy" is responsible for it.

The only ifcfg-eth0 file that you should be concerned with is the one in /etc/sysconfig/network-scripts/.
The others are created automatically from that one. For direct edits, only edit the file in /etc/sysconfig/network-scripts/.

Thumbs up Re: Network not activting on boot

Thanks. All I ended up having to do was to delete the startup (chkconfig --del Networkmanager) and it's working now.
