For jailbroken iOS device, GuizmoDNS is an app to change DNS settings (for 3G/4G and Wifi), with support for DNSCrypt. It is available on Cydia. The command-line dnscrypt-proxy client is also available on Cydia.
dnscrypt-proxy implements the latest revision of the protocol and works on many platforms, including Windows, macOS, Linux, OpenBSD, FreeBSD, NetBSD, Android and iOS. It can be extended with plugins.
Use dnscrypt-proxy, Simple DNSCrypt, and OSXClient to:
- Review the DNS traffic originating from your network in real time, and detect compromised hosts and applications phoning home
- Locally block ads, trackers, malware, spam, and any website whose domain names or IP addresses match a set of rules you define.
- Prevent queries for local zones from being leaked.
- Reduce latency by caching responses and avoiding requesting IPv6 addresses on IPv4-only networks.
- Force traffic to use TCP, to route it through TCP-only tunnels or Tor.
A Docker image for dnscrypt server is also available, and is the easiest and fastest way to deploy a DNSSEC-validating, DNSCrypt-enabled caching DNS server. It includes a pre-configured Unbound server, dnscrypt-wrapper, and all the scripts required to perform key rotation and supervision.
The first line is not required if you are using different IP addresses instead of different ports. The forward-addr lines indicate addresses and ports of dnscrypt clients to use as upstream resolvers.
DNSCrypt wraps unmodified DNS traffic between a client and a DNS resolver in a cryptographic construction in order to detect forgery. Though it doesn't provide end-to-end security, it protects the local network against man-in-the-middle attacks.[1] The free and open source software implementation dnscrypt-proxy additionally integrates ODoH.[1][2]
dnscrypt-proxy is a DNS proxy client with support for the encrypted DNS protocols DNS over HTTPS and DNSCrypt, which can be used to prevent man-in-the-middle attacks and eavesdropping. dnscrypt-proxy is also compatible with DNSSEC.
By leaving server_names commented out in the configuration file, dnscrypt-proxy will choose the fastest server from the sources already configured under [sources] [3]. The lists will be downloaded, verified, and automatically updated [4]. Thus, configuring a specific set of servers is optional.
A full list of resolvers is located at the upstream page or Github. If dnscrypt-proxy has run successfully on the system before, /var/cache/dnscrypt-proxy/public-resolvers.md will also contain a list. Look at the description for servers note which validate DNSSEC, do not log, and are uncensored. These requirements can be configured globally with the require_dnssec, require_nolog, require_nofilter options.
Open the browser and head to DnsLeakTest and do an extended test, if the results show servers that you have set in the configuration files it means that dnscrypt-proxy is working, otherwise something is wrong.
It is recommended to run dnscrypt-proxy as a forwarder for a local DNS cache if not using dnscrypt-proxy's cache feature; otherwise, every single query will make a round-trip to the upstream resolver. Any local DNS caching program should work. In addition to setting up dnscrypt-proxy, you must setup your local DNS cache program.
In order to forward queries from a local DNS cache, dnscrypt-proxy should listen on a port different from the default 53, since the DNS cache itself needs to listen on 53 and query dnscrypt-proxy on a different port. Port number 53000 is used as an example in this section. In this example, the port number is larger than 1024 so dnscrypt-proxy is not required to be run by root.
it all went well and dnscrypt working fine. the next time i turn on the computer i just can't connect to internet. so i tried to uninstall dnscrypt proxy and refollow the guide to undo the change i made but it still doesn't connect. i have no idea what wrong here and i really appreciate any help.
If I reboot, then in Terminal, I issue:
sudo dnscrypt-proxy status
... it says it cannot load the dnscrypt-proxy.toml configuration file, saying it's a FATAL error. Of course, DNS resolution doesn't work then.
I can start it manually after boot, but that's obviously not ideal, as I have to leave a Terminal window open to keep it running. Something's not right with how it's configured to start during boot, and I suspect it's not loading the .toml file, given that's the error I get when checking dnscrypt-proxy's status.
I upgraded to 2.1.2 by downloading the latest from the developer's website, shutting down dnscrypt, extracting the .tar.gz file, then copying over the .bin file, the dnscrypt-proxy.toml configuration file and the dnscrypt-proxy-example.toml example file. I then edited the example file, then saved it as the configuration file.
I get the same behavior... when starting up during boot or restarting the service after boot, it fails after it cannot bind to 127.0.0.2:53 despite nothing else using that port when dnscrypt is shut down:
I used to run dnscrypt-proxy inside of sys-net to encrypt and secure dns-requests. Meanwhile I moved the service to a separate sys-dns and would like to share the setup with the community. Prerequisite is a fedora-36-minimal and fedora-36-minimal-dvm with dnscrypt-proxy installed and disabled.
set in /etc/dnscrypt-proxy/dnscrypt-proxy.toml. I disabled systemd-resolved in the template, it might be possible to deinstall it. Actually I like systemd but sometimes systemd (and others like NetworkManager) do stuff in the background which I do not fully understand.
What happens in sys-dns is: systemctl status dnscrypt-proxy shows that the service starts successfully but for some reason it cannot connect to the network. The last message in the journal is (skipping the timestamps):
and it remains like this forever. The Internet connection is definitely fine - in sys-net I can ping and so on. FWIW, all my config files in /etc/dnscrypt-proxy are taken from another (physical) machine running Linux where they work fine. In case that might be interesting regarding the current issue, in dnscrypt-proxy.toml I have netprobe_timeout = -1.
we still need firewall rules in the network service qube (which will run the dnscrypt-proxy service). Does this remove the need for sys-firewall-2 which only direct DNS traffic to the network service qube? The doc says:
This directory should be the same as the one used in subsections of section [sources] in /etc/dnscrypt-proxy/dnscrypt-proxy.toml. I am using a subdir of /run in order to hopefully have cache in RAM (/run is a tmpfs mount):
So I did some digging around and came across a recommendation to use dnscrypt-proxy instead of cloudflared. After looking at it, I found this a better solution since not only does is support DoH and DNS over TLS (which cloudflared does as well), it also support DNSCrypt. So it is more versatile than cloudflared. Additionally, which I admire what Cloudflare does and provides, I would like to move aware from a single vendor for these type of things, and have something which makes it easy to switch my external DNS name resolver.
ok so i have read many guides on setting up dnscrypt-proxy in linux its very easy and straightforward. So to my understanding i download and install dnscrypt-proxy which i have done via yaST install package center that went fine and i added Add 127.0.0.1 as my dns servers in the network settings. BUT when i reboot i noticed i cant find the service in the list of services to start in yaST>system>service manager. and when i try to start the service i get this

How i understand dnscrypt you can use it with this dnscrypt protocol for really anon DNS resolver like where my client IP address is also hidden from the Resolver.
DoH has not my interest.
I only will fight back my privacy and every step to get a little more invisible is a good step in the right direction.
DNSCrypt runs as user _dnscrypt-proxy by Debian dnscrypt package default. That user on Whonix-Gateway has neither clearnet system default networking access nor torified system default networking access.
dnscrypt-proxy2 is configured with Google DNS and Cloudflare DNS by default.You can change it to Google DNS or any other DoH or DNSCrypt provider.Use resolvers supporting DNSSEC validation if necessary.Specify several resolvers to improve fault tolerance.
