![]() The next steps require some decision making on your part and what you are comfortable with. I have dnscrypt-proxy listening on port 4053 only on IPv4 interfaces. The port number you choose can be to anything you want, but it should not be in the range of 0–1024 or any commonly used ports. You must change the port number if you also have Pi-hole installed. By default, dnscrypt-proxy will listen for DNS requests on port 53 for both IPv4 and IPv6 interfaces. nano dnscrypt-proxy.tomlįind listen_addresses. cd dnscrypt-proxy cp example-dnscrypt-proxy.toml dnscrypt-proxy.tomlĭnscrypt-proxy.toml is the configuration file read by dnscrypt-proxy, so open up a text editor (ie. Now cd into the directory and make a copy of the configuration file in case you make a mistake. This isn’t a great name, so I’ll change it to dnscrypt-proxy. You should now have a directory with the name of the platform for which you downloaded dnscrypt-proxy for. Remove the archive - you don’t need it any more. If your platform is a Raspberry Pi, you’ll want the dnscrypt-proxy-linux_arm-2.0.21.tar.gz release (ARM).ĭownload the archive. For me, at this time of writing, it is dnscrypt-proxy-linux_x86_64-2.0.21.tar.gz, so that is what I will be using here. Next, navigate to the dnscrypt-proxy project page on GitHub and find the most appropriate, latest release for your platform. NOTE: this article assumes you have the appropriate permissions. On your Linux machine, change into the directory you want to download dnscrypt-proxy to. So I’m going to assume that you’re installing/configuring it on a headless machine (ie. SimpleDNSCrypt is a GUI for dnscrypt-proxy, the latter of which is what I’ll be using here. In my previous post, I explained how I used SimpleDNSCrypt to make use of the DNSCrypt protocol. Anyone who has access to the network in the same way as before will only see a bunch of gibberish instead of the domains you are trying to look up. You can think of DNSCrypt as a method of creating a kind of ‘tunnel’ between your computer and a DNS server. Anyone who has access to the network, at any point between your computer and the DNS server, will likely be able to see what domains you are trying to access, and potentially modify the response. The problem is that these requests and responses between your computer and DNS servers are not encrypted. In my case, the DNS servers are operated by the ISP. When your computer wants to connect to, it will use the IP addresses of these DNS servers to lookup 's IP address. If, as in my case, when you connect to the Internet, your ISP will tell your router/modem/gateway where to make DNS requests by giving it one or two IP addresses of DNS servers. ![]() Your computer uses DNS to look up the IP address of a domain before it can connect. DNS does exactly the same thing but for domains. If you want to know a person’s phone number, you need to look it up before you can dial the number. This is where DNS fits in.ĭNS is like a phone book. They need to know the IP address of a domain like first. Computers don’t communicate over networks with names. ![]() When you use your browser to lookup, your computer needs to find out where is. It is beyond the scope of this post on how to install Pi-hole, so just follow the instructions on the Pi-hole website to get started. ![]() I didn’t have a Raspberry Pi at the time I began using Pi-hole, so I installed it on an Ubuntu machine I had instead. Pi-hole is a fantastic piece of software which kills a huge number of ads and other bad stuff™ from your network.
