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 machine, ip a showed eth0… but with the firmware MAC.
And I’m wondering if it went to renew its IP address, and lost the spoofed MAC. That might explain his freezes.
Anyway, does anyone have any idea if there’s some networkmangler or systemd configuration that would force it to pay attention?
Note that my hack to fix it was ifdown eth0/ifup eth0, and it’s fine.
