Hello, I'm not seeing free range routing (frr) packages for CentOS 8. The RHEL8 docs say frr is the replacement for quagga. https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/setting-your-routing-protocols_configuring-and-managing-networking What am i missing? Cheers, Dan

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

...t: If it's not set to 'yes', then you'll want to do so: nmcli connection modify eth0 connection.autoconnect yes As to the 'why,' I don't know.

...e than one adapter. See here if you have access: https://access.redhat.com/solutions/2435891 Anyway perhaps you could manage order of names customizing /usr/lib/systemd/network/99-default.link At least as described here: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/consistent-network-interface-device-naming_configuring-and-managing-networking but I never tried it HIH, Gianluca

...foo.subdomain.company.com has address 1.2.3.4 [root at localhost ~]# The expected result is that the lookup for foo.subdomain works, like it does under CentOS < 8. I tested this also on a RHEL8 machine and followed https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/manually-configuring-the-etc-resolv-conf-file_configuring-and-managing-networking to disable DNS processing by NM, but this did not change the outcome. How can the pre-CentOS 8 behaviour be restored?

I have need to use the old network-scripts and not NetworkManager. I did yum install network-scripts, I have ifcfg-eth0 set for ONBOOT=yes but it is not starting on boot. What have I missed ? Jerry
