On any flavor/version of Linux I have installed in the past, I would install and then $ping yahoo.com and get a very warm fuzzy feeling that networking was working when I would get replies back.
After installing CentOS6, I cannot get networking to work. anyone know why?
I tried:
/etc/rc.d/init.d/network start
but that did nothing.
Is there a conspiracy to keep amateurs & hobbyists off CentOS 6 and leave it to untilmate ninja hackers to get working?
I don't know what is wrong that networking does not seem to work on the box. It is attached to a live, internet wire that worked with Fedora 9.
How does networking start?

No, the conspiracy is to turn everyone into touchscreen users, judging from the latest changes in various things.
Look in /etc/sysconfig/network-scripts for ifcfg-eth0
It probably has (though, this is judging by Fedora, don't know if CentOS has gotten to this point yet,) NM_Controlled=yes
That means, it assumes you want network manager to control your interface. If you're not running network manager, it might not start the interface.
If you post the contents of that file, we can possibly be of more help.
Also, take a look at the links in my signature, you are leaving out some information, such as do you boot into a GUI, if so, which GUI, and so on.

Re: How does networking start?
During the setup, when it comes time to setup the hostname, I click the networking button, and then go into network manager and tell it to activate on boot. (and setup IP info).
I haven't figured out how to do it otherwise yet, but now I will watch this thread :lol:

Well, I have a page, more aimed at troubleshooting wireless in Fedora, but still possibly useful, for getting NM out of the equation.

On the other hand, if you're using Gnome, then there may be no reason to take NetworkManager out of the equation, if it's working for you.

RHEL-6 and thus CentOS-6 default to NetworkManager. I am not happy with this direction either, but it is pretty simple to either turn it off and use the network service, or set it up to start the Ethernet interface at boot time, which should IMNSHO be the default, but is not.

Re: How does networking start?
# vi /etc/sysconfig/network-scripts/ifcfg-eth0
edit so that 'onboot=yes' then save file and reboot. This will enable eth0 on every bootup, the default is set to no, even on minimal install in my experience.
