I have all NetworkManager services masked out. I have network-scripts installed and network enabled. I have these files in /etc/sysconfig/network-scripts: ifcfg-p6p1 looks like: NM_CONTROLLED="no" DHCPV6C="no" DEVICE="p6p1" ONBOOT="yes" PEERDNS="no" HWADDR="00:0B:0E:0F:00:ED" BRIDGE=br0 ifcfg-br0 looks like: NM_CONTROLLED="no" DHCPV6C="no" BOOTPROTO="dhcp" DEVICE="br0" ONBOOT="yes" PEERDNS="no" TYPE=Bridge On fedora 30, br0 automagically shows up with the same MAC as p6p1. On fedora 31, br0 gets the wacky MAC address: 26:b0:0b:12:b4:6c The corporate DHCP service then thinks I have a different hardware and gives me the wrong IP address which doesn't lead to my hostname. Anyone know what is going on? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
