DNScrypt proxy not working [duplicate]

  • 772

I've installed DNScrypt proxy from https://github.com/opendns/dnscrypt-proxy/downloads and installed it under Ubuntu 11.10 x64. I started the proxy by

sudo /usr/sbin/dnscrypt-proxy --daemonize

syslog states

dnscrypt-proxy[2615]: dnscrypt-proxy is ready: proxying from [127.0.0.1] to [208.67.220.220]

I set the dns to localhost and restart the connection by gui. But the local dns can not be reached:

dnscrypt-proxy[2615]: dnscrypt-proxy is ready: proxying from [127.0.0.1] to [208.67.220.220]

netstat

PID/Program name
tcp        0      0 127.0.0.1:53            0.0.0.0:*               LISTEN          2231/dnscrypt-proxy

Someone has an idea? Thanks a lot!

  1. At least for Ubuntu 12.04 the issue is local DNS cache running on 127.0.0.1 (dnsmasq). Webupd8.org has a walk through and a script to change the local listening IP to 127.0.0.2.

    Scroll down to the Ubuntu section. I have it working for both 11.10 x64 and 12.04 x64 using their script. Initially it was not working on 11.10 but a full reboot resolved it.

  2. Try setting the DNS servers to: 208.67.222.222, 208.67.220.220.

  3. Try

    sudo /usr/sbin/dnscrypt-proxy --daemonize --tcp-only

    I think there is a bug in UDP connection to dnscrypt
