My Synology NAS will then take care of pure file related tasks like backups and media management. I’ve decided to use mine for some network related stuff since the fourth version has gigabit Ethernet. Unless you need a lot of processing power it’s good enough to run as a small home server. The Raspberry Pi is a great little computer you can use for many different things.

You can check to see if port 53 is in use or not by running sudo lsof -i :53 - if port 53 is not in use, this command shouldn’t show any output.📆 🍱 server adguard docker privacy dns raspberry pi Port 53 should now be free on your Ubuntu system, and you shouldn’t be getting errors like “listen tcp 127.0.0.1:53: bind: address already in use” anymore. Here, -s is for creating a symbolic and not hard link, and -f is for removing any existing destination files (so it removes /etc/nf if it exists). Create a symbolic link for /run/systemd/resolve/nf with /etc/nf as the destination: To save the file using Nano text editor, press Ctrl + x, then type y and press Enter.Ģ. This is how the file should look after you’ve made these changes (I’m using 1.1.1.1 as the DNS server here, which is the Cloudflare DNS):

127.0.0.1 to use a local proxy, 1.1.1.1 to use the Cloudflare DNS, etc.), and also change the DNSStubListener= value from yes to no. Next, change the DNS= value in this file to the DNS server you want to use (e.g. open it with Nano console text editorĪnd uncomment (remove # from the front of the line) the DNS= line and the DNSStubListener= line. I am new to ubuntu, yet from my research I would suggest editing your nf to free up the port imho.ġ, Edit /etc/systemd/nf with a text editor (as root), e.g.
