Here's the relevant link from the upstream vendor's release notes: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/6.1_Release_Notes/ar01s01.html Naming convention for network interfaces Traditionally, network interfaces in Linux are named eth[X]. However, in many cases, these names do not correspond to actual labels on the chassis. Modern server platforms with multiple network adapters can encounter non-deterministic and counterintuitive naming of these network interfaces. Red Hat Enterprise Linux 6.1 introduces biosdevname, an optional convention for naming network interfaces. biosdevname assigns names to network interfaces based on their physical location. Note, however that biosdevname is disabled by default, except for a limited set of Dell systems. Refer to the Red Hat Knowledge Base for further information on using biosdevname. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] No eth0 on centos 6.2
Just installed centos 6.2. I run and ifconfig -a I see and em1 em2 and lo interface. If I go to /etc/sysconfig/network-scripts, I don't see an ifcfg-eth0. If I run ifup eth0 it comes back with Device eth0 does not seem to be present, delaying initialization. Anybody have a clue? Thanks in advance. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

The 'emX' are likely your interfaces. If you check you should have ifcfg-emX files. If you would like to rename them, you can follow this; https://alteeve.com/w/Changing_the_ethX_to_Ethernet_Device_Mapping_in_EL6_and_Fedora_12%2B That talks about change eth0 - eth1, but it can just as easily be em0 - eth0. -- Digimer E-Mail: digi...@alteeve.com Freenode handle: digimer Papers and Projects: http://alteeve.com Node Assassin: http://nodeassassin.org omg my singularity battery is dead again. stupid hawking radiation. - epitron ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] No eth0 on centos 6.2
I simply decided to set onboot to yes, bootproto to static, and assign an address. Thank you! ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If you would like to rename them, you can follow this; Not sure about RH 6.x, but in Fedora 16 and up, one also should remove the biosdevname package (rpm -e biosdevname) if they want to go back to the ethX naming scheme. http://fedoraproject.org/wiki/Features/ConsistentNetworkDeviceNaming and http://fedoraproject.org/wiki/Talk:Features/ConsistentNetworkDeviceNaming -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6 Buffy: I didn't jump to conclusions.
