I have never had an issue with dns other than with this raspberry setup (and I'd rather keep the things standard in the raspbian side)
I haven't done any configuration changes on the raspberry from the default configuration (other than enabling ssh)
- dhcpd checks:
With the command "sudo dhcpcd -o domain_name_servers -T" I get a lot of information and among it:new_domain_name_servers='192.168.1.19 192.168.1.20 127.0.0.1'
- systemd-resolve checks
With the command "systemd-resolve --status" I get only a single dns server as outputDNS Servers: 127.0.0.1
I could add dnsmasq in the mix, but if possible I would like to have the most standard possible system.
