Yes, they are different, but mostly in the way the device names are managed. Both essentially randomize the order of detection and the numbers each device gets, but in 5.x having the right HWADDR= and mac address in the ifcfg-eth? file was sufficient to rename the device to match the DEVICE= in the file. In 6.x the names are set according to the rules in /etc/udev/rules.d/70-persistent-net.rules (which will be recreated at reboot, possibly in a different order if you delete it after a change). The /etc/sysconfig/networking-scripts/ifcfg-xxx files have to match the DEVICE= and HWADDR= entries to work. There is also some special handling for netbios names in a weak attempt at consistency that only works on certain Dell servers. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] centos 6.4 networking problem
Have you verified MAC address of your two NIC's with their respective network configuration file? Are they same? Sometime that can cause a problem.

The system was working properly at the begining. So I don't understant probably I made a bad modification some where. For now, I scrapped the 6.4 and push back to 5.9 because of a lack of time to get a better understanding of the situation. 6.0 and up seems to be far different from 5 am I wright?

[CentOS] centos 6.4 networking problem
On this system I have two nics If I look at the network connection There is nothing there. If I do ifconfig -a the two nics are there If I do ifup eth0 I get device doesn't seem to be present If I do ifup eth1 the system search to determine the IP information for this device. Do somebody have an idea to bring them up? --- Michel Donais ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
