Correção do DNS

Algumas vezes os servidores Ubuntu 18.04 podem não ser capazes de resolver nomes corretamente. Normalmente esse problema está atrelado ao resolv.conf que está incorreto. Para resolver esse problema de forma permanente siga os passos descritos.

...

Remover o link simbólico atrelando ao arquivo stub.

cd /etc && rm /etc/resolv.conf && ln -s /run/systemd/resolve/resolv.conf


Após isso edite o arquivo resolved.conf.

vim /etc/systemd/resolved.conf


Edite o campo de DNS. Abaixo segue exemplo do arquivo editado:

[Resolve]
DNS=8.8.8.8
#FallbackDNS=
#Domains=
#LLMNR=no
#MulticastDNS=no
#DNSSEC=no
#Cache=yes
#DNSStubListener=yes


Feita a edição reiniciei o serviço systemd-resolved.

service systemd-resolved restart
