Edit the cd /etc/sysconfig/network-scripts/ifcfg-ethX (X is the index of your NIC) according to your network topology and manipulate with the NIC up/down status with commands ifup/ifdown.

eth0 - How to enable?

Postby pschaff » 2011/11/28 21:17:01

CentOS-6 uses NetworkManager by default. If you wish to use the "traditional" network service from the command line then use chkconfig to disable NetworkManager and make sure the network service is running. If etc/sysconfig/network-scripts/ifcfg-eth0 (or whatever your device is named) has a line
Code: Select all
NM_CONTROLLED="yes"
change it to
Code: Select all
NM_CONTROLLED="no"


See also CentOS-6 FAQ #2. Why does my Ethernet not work unless I log in and explicitly enable it?

If more help is needed then please explain the problem more completely and provide more information about your system by running "./getinfo.sh network" and showing us the output file.

I did a minimal CentOS installation on Hyper-V and by default I didn't have network file in /etc/sysconfig/ and ifcfg-eth0 in /etc/sysconfig/network-scripts so I had to create those two files.
