dnsdist runs as the dnsdist user. 2 things might be the case

1. the /var/lib directory is not accessable to all users
2. a protection setting in the systemd service file might prevent thist
(most likely ProtectSystem=full)

Have a look at what might be the culprit here.

Hi,

I think, I ran into the same problem ob Ubuntu 20.04. My solution was, to create an folder /var/log/dnsdist with write-permission to the _dnsdist-User and configured all logfiles for dnsdist to this location.

Best regards,
Markus
