After starting dnscrypt-proxy, you will need to point your
local DNS server to 127.0.0.1. You can do this by going to
System Preferences > "Network" and clicking the "Advanced..."
button for your interface. You will see a "DNS" tab where you
can click "+" and enter 127.0.0.1 in the "DNS Servers" section.
By default, dnscrypt-proxy runs on localhost (127.0.0.1), port 53,
and under the "nobody" user using the default OpenDNS DNSCrypt-enabled
resolver. If you would like to change these settings (e.g., switching to
a DNSCrypt-enabled resolver with DNSSEC support), you will have to edit the
plist file (e.g., --resolver-address, --provider-name, --provider-key, etc.)
To check that dnscrypt-proxy is working correctly, open Terminal and enter the
following command:
dig txt debug.opendns.com
You should see a line in the result that looks like this:
debug.opendns.com. 0 IN TXT "dnscrypt enabled (......)"
Note: This will only work if you are using the default OpenDNS DNSCrypt-enabled
resolver. If you are using a different resolver, you can use a tool like tcpdump
to verify that everything is working correctly.
