DNS

Port 53 already alocated​

If you have any issue related to the port 53, check if you have another DNS server running on your machine (dnsmasq, docksal, ddev dns for example), if so stop it and try again.

Example with docksal :

fin system stop

Example with dnsmaq on MacOS :

sudo brew services stop dnsmasq

Example with dnsmaq on Linux :

sudo systemctl stop dnsmasq
# Can be disabled to avoid restarting it on reboot
sudo systemctl disable dnsmasq

Example with systemd-resolved on Linux :

In the file /etc/systemd/resolved.conf, uncomment this line

/etc/systemd/resolved.conf
[Resolve]
...
DNSStubListener=no

Then replace symlink for /etc/resolv.conf

sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

Add the nameserver:

echo "nameserver 127.0.0.1" | sudo tee -a /etc/resolv.conf

Finally restart systemd-resolved

sudo systemctl restart systemd-resolved
