I installed a Centos 6.2 min install. I have edited /etc/sysconfig/network-scripts and I have ifcfg-eth0,eth1

I have tried to setup static IPs but I only get IPV6 address back on both adapters and can't ping anything since the rest of the network is IPV4.

I have copied my working settings from another Centos 6 server I have setup and working. Not sure what to do next?

I already added a line to say NETWORKING_IPV6=no

Please post the ifcfg scripts so we can take a look! Is your network manager set to IPV6 (if it's installed)? If network manager is running, it'll override your static settings unless you explicitly say to not manage the interface. – FloppyDisk Mar 20 '12 at 11:19

Something along the lines of this in your ifcfg-eth0 file should work:


If you're having trouble, posting your network scripts would be helpful.

I will try that when I get home and let you know thanks. I have edited in and out so many times. Was starting to think problem with 6.2??? Used same settings as my other working server 6.0, and didnt work. – Rodger Bruce Mar 21 '12 at 20:39
ok mine is just like your except i have hardware= for network adapter that was already there. I also have a gateway and 2 dns addresses defined. still not working. – Rodger Bruce Mar 22 '12 at 0:35
I have tried editing also probmode.conf files as some suggested along with network file. Im at the point of reinstalling with Centos 6.0 instead of 6.2. I have a 6.0 version running fine with static ipv4 no problems. – Rodger Bruce Mar 22 '12 at 23:03
Loaded Centos 6.0 network adapters working fine ipv4. – Rodger Bruce Mar 23 '12 at 2:44
