Dear all,

I have installed centos 6.4 in a server but now the network doesn't seem to work.When i try to start or restart the network, it gives me the following error:

Code:

eth0 device not present , delaying initialization

It was working perfectly fine before...So can anyone please tell what must have gone wrong?

Is there any error or warning in boot-up message? What's output, lspci?

SarahGurung · 10-08-2013, 10:09 PM

well the one that i pasted above is the error.

lspci and mii-tool shows that the device eth0 and eth1 is not present. Don't know what could be the issue.

If NIC device isn't in lspci, hardware and driver module should be checked.

SarahGurung · 10-09-2013, 11:28 PM

well how should that be done?

Check the network config files to see if it's trying to bind eth0 / eth1 to specific MAC addresses. I've seen similar problems when the network subsystem was replaced in a server, and also in a virtual server where the VM settings assigned pseudo-random MAC addresses to the VM on reboot.

The error you posted above isn't from boot-up message and is from network starting. Based on the error information, hardware or driver could have problem.
Using dmesg command can check boot-up message. The information in dmesg can tell you where is problem, hardware or driver.
