![]() ![]() How to check status of DNS on Ubuntu Desktop and Ubuntu Server: You can check settings from the netplan conf fileĬat /etc/netplan/00-installer-config.yaml.How to check Ubuntu SERVER DNS settings and status: Nmcli -t -f IP4.DNS device show $interface_name As pointed out You can check settings from nmcli:.How to check Ubuntu Desktop DNS settings and status: Dont change this file, stop looking at it, stop messing with it.
