similar to: eno1 and eth0 on centos 7.1

I have installed CentOS 7. I added "biosdevname=0 net.ifnames=0" at install time. I still have a network name of en01 and not eth0. How do I get eth0 when viewing ifconfig? dmesg | grep eth0 show its being detected, and being renamed. systemd-udev renaming eth0 to en01... I then looked in /etc/udev and dont see anything of value... Thanks, Jerry

There may be ways to force NIC naming, I've done so but only on Ubuntu so you'll need to do the research if it's important to you. Things to look for based on my experience: 70-persistent-net.rules, net.ifnames=0, biosdevname=0. ________________________________ From: CentOS <centos-bounces at centos.org> on behalf of Nicolas Kovacs <info at microlinux.fr> Sent: Sunday,

I have built a CentOS 8 base image from a kickstart, for use in OpenStack. This image boots fine but the problem I have is that I can't stop udev from renaming the network device from eth0 to ens<something>. I have /etc/sysconfig/network-scripts/ifcfg-eth0 with the correct HWADDR defined in it, and have set net.ifnames=0 and biosdevname=0 in the grub configuration, but nothing I have

Odd situation: I've mentioned before that I have several users for whom I have to spoof the MAC address, due to a software license. Now, I've got net.ifnames=0 biosdevname=0 on the grub2 command line, and I've got the spoofed MAC address in /etc/sysconfig/network-sctipts/ifcfg-eth0. But he had a serious problem - X froze, and he thought to reboot, rather than call me. It came up with

Hi, I am currently struggling with the right way to configure a bonding device via kickstart (via PXE). I am installing servers which have "eno" network interfaces. Instead of the expected bonding device with two active slaves (bonding mode is balance-alb), I get a bonding device with only one active slave and an independent, non-bonded network device. Also the bonding device

Got a problem: a user's workstation froze. He wound up rebooting, without calling me in first, so I dunno. But, and this is a show-stopper, when it came up, it came up with the firmware MAC, not the spoofed one. In /etc/sysconfig/network-scripts/ifcg-eth0, I've got the spoofed MAC address, and a UUID. In the grub.conf, I've got net.ifnames=0 biosdevname=0. But when I logged onto his

Here is my script for post install if you want to try it. In order for the shuffling to not occur you do need to create the udev rules file somehow. I am not sure how mangled this will be in email but it is worth a try. It should run OK with nothing else. I have a better version in the works but the enhancements are mainly useful for Fedora 19-21. I did forget to say I also block

Dear Simon, every second IP-address is unwanted. We restarted? eno4: nmcli con down eno4; nmcli con up eno4 and the second address vanishes. Then after a few ours, the second ip address reappears.

This should be easy to answer (I hope).? We routinely kickstart boxes to use for managing our customers RADIUS/DHCP configurations (along with other things).?

Hi, I encountered a problem when creating a VLAN interface according to the Red_Hat_Enterprise_Linux-7-Networking_Guide. I configuered the parent interface ifcfg-eno1 as follows: DEVICE=eno1 TYPE=Ethernet BOOTPROTO=none ONBOOT=yes And I created a new file named ifcfg-eno1.5, the content is: DEVICE=eno1.5 BOOTPROTO=none ONBOOT=yes IPADDR=192.168.81.3 PREFIX=24

Define out of order in this case just so I know for sure what you mean. What my solution does, or at least does reliably in my case, is make sure the interfaces are in the same order once installed as the install kernel saw them. It won't re-order them to be sequential based on bus, mac or driver. I am working on that but it will also include naming the devices based on the module

Starting back in RHEL/Cent 5 I found that the only way to make sure your interface enumeration was consistent after install with what you had during install was to create a udev rules file using the mac addresses as the key. It is easy to run a short script in postinstall to create it based on how anaconda has seen them. In order for this to work on Cent 6 you have to set biosdevname=0

The issue here may be systemd (I've seen/agree with the venting, this is another example). If you're getting non-eth names there's a program called biosdevname which may be deciding how to name NICs for you. If that's the case then then the <nn>-net.rules may be ineffective unless the following is added as kernel command line parameters: net.ifnames=1 and biosdevname=0 I
