1.1.1.1 - DNSCrypt/dnscrypt-proxy GitHub Wiki

In somecases if you want to run dnscrypt-proxy as a non-root user you'll get the error "[FATAL] listen udp 0.0.0.0:53: bind: permission denied"

to solve this problem you can run the following command and allow dnscrypt to have access to a low level port :

sudo setcap cap_net_bind_service=+ep $(which dnscrypt-proxy)
