Why is my ethernet not working?

I’m using Fedora 9 and am unable to start network on my distro. Can anyone help me start networking or at least find eth0 hardware address so that I can edit my eth0 file?

My network card is not shown when I execute:

ifconfig -a 

lspci shows my ethernet card is present as:

02:00.0 Ethernet controller : Realtek semi......RTL8111/8168B PCI EXPRESS GIGA.....CONTROLLER
