Check the IP address of the resolver in use using: $ systemctl status dnscrypt-proxy You can change it after you know everything works, if you want.
#Opendns dnscrypt for windows installer install
Installation and startup is easy: apt install dnscrypt-proxyĬheck to make sure it is running and determine which IP/port it listens on: $ lsof -i -n | grep dnscryptĭnscrypt- 27114 _dnscrypt-proxy 3u IPv4 15407729 0t0 TCP 127.0.2.1:domain (LISTEN)ĭnscrypt- 27114 _dnscrypt-proxy 4u IPv4 15407730 0t0 UDP 127.0.2.1:domainīy default dnscrypt is configure to use the OpenDNS/Cisco resolver and I suggest you keep using it during setup because they offer a nifty utility to validate you are dnscrypt enabled. What we will end up with is this:ĭnscrypt-proxy Installation and First Run My goal is to insert dnscrypt-proxy into the DNS query flow to encrypt all queries along as they transit the untrusted zone.
A rough diagram of how DNS queries flow through my network is below, where green indicates a trusted zone or encrypted link, and red indicates untrusted/unencrypted. I run BIND on my Ubuntu-based mini-PC router.
I decided to set up dnscrypt-proxy as a forwarder on my home router so that all DNS traffic leaving my network is encrypted.
This toolset and infrastructure encrypts DNS queries from your machine or network so that your ISP can’t snoop on them. I’m always looking for ways I can add layers of encryption and security to my network and I recently came across the DNSCrypt project created by OpenDNS.
