--rpclisten=[::]:8334	all IPv6 interfaces on port 8334
--rpclisten=127.0.0.1:8334	only IPv4 localhost on port 8334
--rpclisten=[::1]:8334	only IPv6 localhost on port 8334
--rpclisten=:8336	all interfaces on non-standard port 8336
--rpclisten=0.0.0.0:8336	all IPv4 interfaces on non-standard port 8336

1. Copy rpc.cert to /usr/share/ca-certificates: # cp /home/user/.btcd/rpc.cert /usr/share/ca-certificates/btcd.crt
2. Add btcd.crt to /etc/ca-certificates.conf: # echo btcd.crt >> /etc/ca-certificates.conf
3. Update the CA certificate list: # update-ca-certificates
