Can't bring up eth0 or eth1 after replacing main harddrive (centos)

abefroman · 08-10-2013, 08:41 AM

I replaced the harddrive on my box with one with centos preinstalled (the previous drive with centos went bad).

However it would not let me bring up any of the eth interfaces and would give the error:

Code:

]#ifup eth0
Device eth0 does not seem to be present, delaying initialization.

If there a way to get it to recognize the interfaces without reinstalling the OS?

TIA

Post the output of

Code:

ifconfig -a

and

Code:

cat /etc/sysconfig/network-scripts/ifcfg-eth0

Hmm.. looks like no driver for your ethernet. What hardware do you have?

Easiest way to check is

Code:

lspci |grep Ether

abefroman · 08-10-2013, 10:32 AM

# lspci |grep Ether
0d:00.0 Ethernet controller: Intel Corporation 82573E Gigabit Ethernet Controller (Copper) (rev 03)
0f:00.0 Ethernet controller: Intel Corporation 82573L Gigabit Ethernet Controller

Please try:

Code:

modprobe e1000
ifconfig -a

Have you found the solution yet?

A lot of times if /etc/sysconfig/network-scripts/ifcfg-eth* has a detailed "static" configuration it will not work on any other box as is... being preconfigured, I'm guessing this is the issue.

The OP stated that he installed a new harddisk with an pre-installed OS. I bet he's having problems with udev rules.
@abe Check in /etc/udev/rules.d. There should be a net-persistent rules file. Remove all references to the eth devices and restart your system.

Cheers

yes you can remove 70-persistent-net.rules in cd /etc/udev/rules.d/ and must restart the box.
