It's a long standing bug in NetworkManager. You *should* be able to disable this globally - you cant. What you can do is set "ipv4.dhcp-send-hostname no" for EACH connection. You would, of course, have to do this before connecting for the first time to avoid leaving trace. Some Alternatives : Dont use NM - its' horrible anyway. Dont use Qubes default names for system qubes - good practice in any case. Use a throwaway random name (like Windows-PC-2456) for whatever you use for sys-net. You can set up a simple script to do this each time you start your Qubes box,providing you have disabled relevant autostarts. I think this is best practice. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
