But since were speaking about a virtual interface, and the feature were talking about is a hardware feature, implemented by manufacturers such as intel inside their ethernet silicon to offload the Checksum calculations from the CPU, consider this thing just a naggie and no more.

But generating only this file for CentOS networking simply isnt enough.

Modify etcsysconfignetwork-scriptsifcfg-eth0 to match the MAC of the full-speed NIC Modify etcudevrules.d70-persistent-net.rules as follows: The first device (usually tulip, change the mac addr to match the full-speed NIC.

Save that file, and run this command: chattr i etcudevrules.d70-persistent-net.rules Reboot.

I set my network config to DHCP and want it that way in the CentOS install.

Can someone please pass on what I need to to have my eth0 enabled.

Thanks in advance Ray.

Please see the recommended reading for new users linked in my signature.

See url FAQ 2. Why does my Ethernet not work unless I log in and explicitly enable iturl That may explain the issue but fixing it in a minimal install may be a bit more tricky.

You could have a look at the command-line tools bnm-toolb and bnmclib or you could disable bNetworkManagerb and use the old bnetworkb service with bsystem-config-network-tuib.

A working bNetworkManagerb etcsysconfignetwork-scriptsifcfg-eth0 example: codeDEVICEeth0 NMCONTROLLEDyes ONBOOTyes HWADDR00:1F:D0:0E:6E:ED TYPEEthernet BOOTPROTOdhcp DEFROUTEyes PEERDNSyes PEERROUTESyes IPV4FAILUREFATALyes IPV6INITno NAMESystem eth0 UUID5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03code Obviously the HWADDR and UUID would be different for your system.

If using the bnetworkb service then you need bNMCONTROLLEDnob.

Thanks again for the help and hope this helps someone else in the future.

Centos Minimal Network How To Enable Networking

I did not explicitly recommend reinstalling to fix the issue as the question was about how to enable networking on the already installed system.

Anyway, glad you are up and running, and thanks for reporting back.
