Hello,
I've recently updated my laptop to F31. Then I was no longer
able to ssh into it. After a little debugging... it turns
out my laptop was not getting the expected ip address
from DHCP. The reason for that was the MAC address it was
sending to dhcpd had change!!! Looking at the interfaces
bridge0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.31.1.175 netmask 255.255.0.0 broadcast 172.31.255.255
inet6 fe80::98f9:f0d0:4b79:cdaa prefixlen 64 scopeid 0x20<link>

TX packets 256704 bytes 39319273 (37.4 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
enp0s31f6: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
ether 8c:16:45:fe:c1:f1 txqueuelen 1000 (Ethernet)
RX packets 355186 bytes 134328851 (128.1 MiB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 256743 bytes 40395059 (38.5 MiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 16 memory 0xec200000-ec220000
The bridge0 interface has as different MAC that the enp0s31f6 interface.
How can that be?? Esp when the hardware address (HWADDR=8C:16:45:FE:C1:F1)
is set in the ifcfg-bridge0_slave_1.
What has changed and where is the bridge MAC address coming from???
tia,
steved.
