ping: unknown host error
 

I get a "ping: unknown host" error when I try to ping.

etc/resolv.conf:
etc/sysconfig/ifconfig.eth0:
etc/hosts:
Can anyone check the attachment to see if eth0 is booted up correctly ? eth0 is up but before that there is some patch error.
Btw, every output has [OK] at the right end which cannot be seen in the attachment.

"link down" is the opposite of up.

I would try providing that firmware it's trying to load. Have you tried that? It's not hard to find a firmware file named rtl8168g-2.fw on the Internet. If this were happening to me, I would compile the kernel with the Ethernet driver not built in (module instead) and copy that firmware file to /lib/firmware/rtl_nic (or whatever dir the realtek stuff is in). It's a harmless and reversible thing to try anyway.

Thank you stoat. I will do that. But for now I have solved the problem. I was using the wrong ip address for my interface.
