d-prox is a DNS proxy which tunnels DNS requests over a SOCKS proxy using TCP. This allows you to use a SOCKS proxy (e.g. Tor) for name resolution.

0.1

Open up d-prox.h in a text editor and change the configuration to suit your requirement.

Examples:

1. For running d-prox with Tor Browser. Assuming tor is running on 127.0.0.1 using port 9050

````d-prox.h```

#define DNS_PORT "53" //port to listen on
#define SOCKS_PORT "9050" //port to connect to (port of SOCKS proxy)(Tor)
#define DNS_SERVER "0.0.0.0" //address to listen on
#define SOCKS_SERVER "127.0.0.1" //address of SOCKS proxy(Tor)
#define REMOTE_DNS_SERVER "8.8.8.8" //dns server to be used by proxy for name resolution (Google DNS)

1. Using a remote machine as a SOCKS Server for DNS Resolution. This requires the remote machine to be accessible remotely via the host. If you are using a public IP, this can be done my using a service such as http://dynu.com. If the machine is behind a NAT, you will also have to set up port forwarding for this machine.

On the Ubuntu machine to be used as the SOCKS server, run the following command to set it up as a SOCKS proxy

ssh -N -D 0.0.0.0:8888 localhost

Then on the host machine

````d-prox.h```

#define DNS_PORT "53" //port to listen on
#define SOCKS_PORT "8888" //port to connect to (port of SOCKS proxy)(port of remote machine)
#define DNS_SERVER "0.0.0.0" //address to listen on
#define SOCKS_SERVER "192.168.43.75" //address of SOCKS proxy(address of remote machine)
#define REMOTE_DNS_SERVER "8.8.8.8" //dns server to be used by proxy for name resolution (Google DNS)

d-prox works on Linux and OS X. To install, download and unzip the repository.

$ cd d-prox
$ make

If the configuration d-prox.h is changed, run make again.

You need to run this program as root because it binds to port 53 of your local machine. To change this, edit d-prox.h.

$ [sudo] ./d-prox

To test if the program is working:

$ dig @127.0.0.1 google.com [-p <port> (if you have changed the default port)]
