Does dom0 keep any logs of your randomized mac adresses for connecting to wifi?

[webmazter]

in either 4.1 or 4.2?

[Felicia]

yes

[webmazter]

How do you delete the log and stop this?

The qubes logs are in dom0 /var/log/xen/console/ directory.
You can delete them and mount this directory as tmpfs:

After setting /var/log to tmpfs, all VMs refuse to start up

Untested: Configure /var/log mount to tmpfs in /etc/fstab: tmpfs /var/log tmpfs defaults,noatime,size=32M 0 0 You can get the directories and subdirectories with their permissions with this command: [user@dom0 ~]$ sudo find /var/log -type d -exec stat -c 'd %n %a %U %G -' {} \; d /var/log 755 root root - d /var/log/journal 2755 root systemd-journal - d /var/log/private 700 root root - d /var/log/xen 770 root qubes - d /var/log/xen/console 2750 root qubes - d /var/log/chrony 750 chrony chrony…

Actually dom0 doesn’t connect to WiFi and doesn’t run any networking code, sys-net does. AFAIK all related logs should only be in sys-net, which, if disposable, is reset every reboot by itself.

The VM is made by Xen, Dom0 does have the log, and you can see the base HW address in the log file

The qube console logs are stored in /var/log/xen/console/ directory.
You can check the /var/log/xen/console/guest-sys-net.log and you’ll see all its log including NIC MAC address.

Thanks for correction! I expected a stronger isolation of the hardware from dom0.
