im trying to configure a DNS Server on a VM (VirtualBox). OS is Ubuntu 18.04. I used netstat -tulpn and no port were being used. Can anyone help me?

Error:

My named.conf.local:

//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";

zone "nome.com.br"
{
        type master;
        file "/etc/bind/nome.com.br.forward";
        allow-transfer { 192.168.2.75; };
};

My nome.com.br.forward file:

;
; BIND data file for local loopback interface
;
$TTL    604800
@       IN      SOA     ns1.nome.com.br. root.nome.com.br. (

And /etc/resolv.conf file:

Do you have another DNS server installed and running?

no, I configured only this one, and as I said, none process is using any port...

but the server says differently: "creating TCP socket: address in use"

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
