Hi,
I have installed HestiaCP with no DNS (bash hst-install.sh -k no -s hostname -e [email protected] -p password). After the installation when I go to Firewall I see that port 53 TCP & UPD is opened but I choose to not install the DNS option. So when I not select the DNS parameter to install is any service that use this port? I want to use port 53 with a another service and I have some error, show me that this port is used somewhere?
