# DNS Over HTTPS Proxy
[](https://travis-ci.org/facebookexperimental/doh-proxy)
[](https://badge.fury.io/py/doh-proxy)
A set of python 3 scripts that supports proxying DNS over HTTPS as specified
in the [IETF Draft draft-ietf-doh-dns-over-https](https://tools.ietf.org/html/draft-ietf-doh-dns-over-https-13).
DOH provides a way to run encrypted DNS over HTTPS, a protocol which can freely
traverse firewalls when other encrypted mechanism may be blocked.
The project comes with a set of 4 tools:
* [doh-proxy](#doh-proxy): A service that receives DOH queries over HTTP2 and forwards them
to a recursive resolver.
* [doh-httpproxy](#doh-httpproxy): Like `doh-proxy` but uses HTTP instead of HTTP2.
The main intent is to run this behind a reverse proxy.
* [doh-stub](#doh-stub): A service that listens for DNS queries and forwards them to a DOH server.
* [doh-client](#doh-client): A tool to perform a test DNS query against DOH server.
See the `CONTRIBUTING` file for how to help out.
DOH Proxy was created during [IETF Hackathon 100](https://www.ietf.org/how/runningcode/hackathons/100-hackathon/) as a proof-of-concept and is not used at Facebook.
You are welcome to use it, but be aware that support is limited and best-effort.
## Installing
To install an already packaged version directly from PyPi:
```shell
$ pip3 install doh-proxy
```
## Usage
### doh-proxy
`doh-proxy` is a stand alone server answering DOH request. The proxy does not do
DNS recursion itself and rather forward the query to a full-featured DNS
recursive server or DNS caching server.
By running `doh-proxy`, you can get and end-to-end DOH solution with minimal
setup.
```shell
$ sudo doh-proxy \
--upstream-resolver=::1 \
--certfile=./fullchain.pem \
--keyfile=./privkey.pem
```
### doh-httpproxy
`doh-httpproxy` is designed to be running behind a reverse proxy. In this setup
a reverse proxy such as [NGINX](https://nginx.org/) would be handling the
HTTPS/HTTP2 requests from the DOH clients and will forward them to
`doh-httpproxy` backends.
While this setup requires more upfront setup, it allows running DOH proxy
unprivileged and on multiple cores.
```shell
$ doh-httpproxy \
--upstream-resolver=::1 \
--port 8080 \
--listen-address ::1
```
`doh-httpproxy` now also supports TLS, that you can enable passing the
args `--certfile` and `--keyfile` (just like `doh-proxy`)
### doh-stub
`doh-stub` is the piece of software that you would run on the clients. By
providing a local DNS server, `doh-stub` will forward the DNS requests it
receives to a DOH server using an encrypted link.
You can start a stub resolver with:
```shell
$ doh-stub \
--listen-port 5553 \
--listen-address ::1 \
--domain foo.bar \
--remote-address ::1
```
and query it.
```shell
$ dig @::1 -p 5553 example.com
```
### doh-client
`doh-client` is just a test cli that can be used to quickly send a request to
a DOH server and dump the returned answer.
```shell
$ doh-client \
--domain dns.dnsoverhttps.net \
--qname sigfail.verteiltesysteme.net \
--dnssec

## Development
### Requirements
* python >= 3.5
* aiohttp
* aioh2
* dnspython
### Building
DOH Proxy uses Python'setuptools to manage dependencies and build.
To install its dependencies:
```shell
$ python3 setup.py develop
```
To build:
```shell
$ python3 setup.py build
```
To run unittests:
```shell
$ python3 setup.py test
```
To run the linter:
```shell
$ python3 setup.py flake8
# Also run flake8 on the testing files
$ flake8 test
```
From within the root of the repository, you can test the proxy, stub and client respectively
by using the following commands:
```shell
$ sudo PYTHONPATH=. ./dohproxy/proxy.py ...
```
```shell
$ PYTHONPATH=. ./dohproxy/httpproxy.py ...
```
```shell
$ PYTHONPATH=. ./dohproxy/stub.py ...
```
```shell
$ PYTHONPATH=. ./dohproxy/client.py ...
```
