stubby VS dnscrypt-proxy

Let's use patchelf to reduce the Docker image size for Stubby — a name resolver that supports DNS-over-TLS. We will use Debian as the base image but the process is specific neither to this Linux distribution nor to this application.

U used Stubby for a while, that worked but I've since switched to Unbound.

Overall, while DoT, DoH, and DNSCrypt are all far better than nothing in terms of privacy and security, I would say that DoH is probably the simplest and most effective choice for the average user, while DNSCrypt (or DoT with a flexible client like Stubby) are preferable for users who desire more robust configuration options, or have niche use cases. I tend toward DoH for devices that frequently travel with me, and DNSCrypt or DoT for devices that rarely leave my home.

For encrypted DNS, I suggest you to install Stubby. It can be used along with a VPN. The Arch wiki is very good as well as the official website to explain how to install it. But the best tutorial is from LinuxBabe.

You can also use any of three different encryption methods (DoT, DoH, or DNScrypt) to encrypt your query when you send it to us (look at Stubby as an example of how to do that).

There is more than one way to do this but I have decided to use dnscrypt-proxy. We will not be using dnscrypt for the dnscrypt protocol though you could elect to use that as the underlying DNS protocol. dnscrypt-proxy lets's us use a SOCKS5 proxy through which the DNS queries will be sent. We will use a Tor SOCKS5 proxy here. You can choose which protocols should be enabled and which ones should be disabled. There are two points:

I tried installing the RPM from the Fedora repos but it's out-of-date and there were no instructions on how to get it operational, so I went with the manual approach as per their wiki: https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Installation-linux

This is awesome, thanks -- going to look into that now. I found SmartDNS interesting and thought I would share it, it's pretty simple to setup. I can see why it's Chinese focused, they have "interesting" internet access over there :-).

I have been looking into DNS quite a bit lately (Unbound, etc), as DNS lookup performance has been pretty subpar lately. I'm in Perth, Australia, and we're pretty remote so our latency is meh at best, and Cloudflare performance has been all over the shop lately, I think they're having issues in WA). DNS can also cause really routing issues here sometimes as we get better latency to Singapore than Sydney, so we might get shunted off to SG.

I've also been using dnscrypt-proxy2 (https://github.com/DNSCrypt/dnscrypt-proxy) for a while, but the above issues with Cloudflares DNS is what triggered me to look into other options.

I use a min-cache-ttl of 15 minutes, which seems to work well.

Thank you for sharing this tip about, looking into this now :).

Sure. I run dnscrypt_proxy behind a pihole. https://github.com/DNSCrypt/dnscrypt-proxy
