sys-whonix starting spontaneously after update

Support
#1

After a recent dom0(?) / TemplateVM(?) update sys-whonix has been starting spontaneoulsy. If I shut it down it starts right back up. I use a different naming convention to prevent confusion between, for example my Tor versioning based VMs and my default whonix-gw based VMs. I don’t often use my sys-whonix “named” VM. sys-whonix is not set to autostart, no VMs have sys-whonix as netvm and I don’t have sys-whonix set as default qubes-prefs or updatevm.

Journalctl output from dom0 keeps showing sys-whonix (sdwdate) logs to VMs that are not even conected to sys-whonix

Anything that can be done if using multiple named DispVMs (based on the same dvm) with each named DispVM using a differnt sys-whonix-VM? For Example

anon-whonix-disp-1 is based on whonix-dvm-1 which uses sys-whonix-1 as netvm.

anon-whonix-disp-2 is based on whonix-dvm-1 which uses sys-whonix-2 as netvm.

pretty sure I know the answer. :frowning_face:

Edit: What if someone wants to change the netvm of their anon-whonix DispVM from sys-whonix-1 to sys-whonix-2 on the fly?

If /usr/local/etc/sdwdate-gui.d/50_user.conf contains gateway=sys-whonix-1 wouldn’t it cause issues if netvm is changed to sys-whonix-2?

Note: in the context of NOT disabing sdwdate autostart

Yes, that config file is a bash fragment. Therefore supports scripting. The contents of the gateway setting variable could be derived from output of qubesdb-read /name.

Will still send sdwdate-gui notifications to old gateway.

Tested in simulation (setting vm_name variable) but not actually tested on real system.

set -x
set -e

vm_name="$(qubesdb-read /name)"

## example vn_name:
## anon-whonix-disp-1

vm_number="$(echo "$vm_name" | str_replace "anon-whonix-disp-" "")"

## example vm_number:
## 1

target_gateway="sys-whonix-${vm_number}"

## example target_gateway:
## sys-whonix-1

gateway="$target_gateway"

Works for me. No issues since using the script. Thank You!
