Hi, if you setup MAC randomization via network manager in a debian 9 template as described here: https://www.qubes-os.org/doc/anonymizing-your-mac-address/ you still leak your hostname.
Once your MAC address is randomized you might also want to prevent the disclosure of your netvm's hostname to the network, since "sys-net" might be a unique hostname (that links all your random MAC addresses and the fact that you likely use qubes). To prevent the hostname leak via DHCP option (12): - start the debian 9 template - open the file /etc/dhcpd/dhclient.conf - in line number 15 you should see "send host-name = gethostname();" - comment (add "#" at the beginning) or remove that line and store the file - reboot your netvm I tested the change via inspecting dhcp requests and can confirm that the hostname is no longer included in dhcp requests. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
