OONI, the Open Observatory of Network Interference, is a global observation network which aims is to collect high quality data using open methodologies, using Free and Open Source Software (FL/OSS) to share observations and data about the various types, methods, and amounts of network tampering in the world.

"The Net interprets censorship as damage and routes around it."

• John Gilmore; TIME magazine (6 December 1993)

ooniprobe is the first program that users run to probe their network and to collect data for the OONI project. Are you interested in testing your network for signs of surveillance and censorship? Do you want to collect data to share with others, so that you and others may better understand your network? If so, please read this document and we hope ooniprobe will help you to gather network data that will assist you with your endeavors!

Running ooniprobe is a potentially risky activity. This greatly depends on the jurisdiction in which you are in and which test you are running. It is technically possible for a person observing your internet connection to be aware of the fact that you are running ooniprobe. This means that if running network measurement tests is something considered to be illegal in your country then you could be spotted.

Furthermore, ooniprobe takes no precautions to protect the install target machine from forensics analysis. If the fact that you have installed or used ooni probe is a liability for you, please be aware of this risk.

On Debian testing or unstable:

sudo apt-get install ooniprobe

On Debian stable (jessie):

echo 'deb http://ftp.debian.org/debian jessie-backports main' | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get install ooniprobe

On Ubuntu 16.04 (xenial), 15.10 (wily) or 14.04 (trusty):

echo 'deb http://deb.torproject.org/torproject.org $RELEASE main' | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get install ooniprobe

Note: You'll need to swap out $RELEASE for either xenial, wily, or trusty. This will not happen automatically. You will also need to ensure that you have the universe repository enabled. The universe repository is enabled by default in a standard Ubuntu installation but may not be on some minimal on not standard installations.

On unix systems:

sudo pip install ooniprobe

To install it from the current master run:

sudo pip install https://github.com/TheTorProject/ooni-probe/archive/master.zip

Then run:

mkdir my_decks
oonideckgen -o my_decks/

If you're using the Debian package, you will be asked when installing whether you would like to run OONI daily. On other platforms, if you would like to contribute measurements to OONI daily you can also add this to your crontab:

@daily ooniprobe $THE_OONI_COMMAND

Run this command to automatically update your crontab:

(crontab -l 2>/dev/null; echo "@daily ooniprobe $THE_OONI_COMMAND") | crontab -

You can install ooniprobe on OSX if you have installed homebrew (http://mxcl.github.io/homebrew) with:

brew install ooniprobe

Make sure you have installed the following dependencies:

• build-essential
• python (>=2.7)
• python-dev
• pip
• libgeoip-dev
• libdumbnet-dev
• libpcap-dev
• libssl-dev
• libffi-dev
• tor (>=0.2.5.1 to run all the tor related tests)

On debian based systems this can generally be done by running:

sudo apt-get install -y build-essential libdumbnet-dev libpcap-dev libgeoip-dev libffi-dev python-dev python-pip tor

Then you should be able to install ooniprobe by running:

sudo pip install ooniprobe

or as a user to install inside a virtualenv:

pip install ooniprobe

1. Install Vagrant (https://www.vagrantup.com/downloads.html) and Install Virtualbox (https://www.virtualbox.org/wiki/Downloads)
2. On OSX:

If you don't have it install homebrew http://mxcl.github.io/homebrew/:

brew install git

On debian/ubuntu:

sudo apt-get install git

3. Open a Terminal and run:

   git clone https://git.torproject.org/ooni-probe.git
   git clone https://github.com/TheTorProject/ooni-backend.git
   cd ooni-probe/
   vagrant up

4. Login to the box with:

   vagrant ssh

ooniprobe will be installed in /ooni.

5. You can run tests with:

   ooniprobe blocking/http_requests -f /ooni/var/example_inputs/alexa-top-1k.txt

Net test is a set of measurements to assess what kind of internet censorship is occurring.

Decks are collections of ooniprobe nettests with some associated inputs.

Collector is a service used to report the results of measurements.

Test helper is a service used by a probe for successfully performing its measurements.

Bouncer is a service used to discover the addresses of test helpers and collectors.

You may edit the configuration for ooniprobe by editing the configuration file found inside of ~/.ooni/ooniprobe.conf.

By default ooniprobe will not include personal identifying information in the test result, nor create a pcap file. This behavior can be personalized.

To generate decks you will have to update the input resources of ooniprobe.

This can be done with:

ooniresources

If you get a permission error, you may have to run the command as root or change the ooniprobe data directory inside of ooniprobe.conf.

You can generate decks for your country thanks to the oonideckgen command.

If you wish, for example, to generate a deck to be run in the country of Italy, you can do so (be sure to have updated the input resources first) by running:

oonideckgen --country-code IT --output ~/

You will now have in your home a folder called deck-it, containing the ooni deck (ends with .deck) and the inputs. Note: that you should not move the deck-* directory once it has been generated as the paths to the inputs referenced by the test in the deck are absolute. If you want your deck to live in another directory you must regenerated it.

You will find all the installed decks inside of /usr/share/ooni/decks.

You may then run a deck by using the command line option -i:

As root:

ooniprobe -i /usr/share/ooni/decks/mlab.deck

Or as a user:

ooniprobe -i /usr/share/ooni/decks/mlab_no_root.deck

Or:

As root:

ooniprobe -i /usr/share/ooni/decks/complete.deck

Or as a user:

ooniprobe -i /usr/share/ooni/decks/complete_no_root.deck

The above tests will require around 20-30 minutes to complete depending on your network speed.

If you would prefer to run some faster tests you should run: As root:

ooniprobe -i /usr/share/ooni/decks/fast.deck

Or as a user:

ooniprobe -i /usr/share/ooni/decks/fast_no_root.deck

You may list all the installed stable net tests with:

ooniprobe -s

You may then run a nettest by specifying its name for example:

ooniprobe manipulation/http_header_field_manipulation

It is also possible to specify inputs to tests as URLs:

ooniprobe blocking/http_requests -f httpo://ihiderha53f36lsd.onion/input/37e60e13536f6afe47a830bfb6b371b5cf65da66d7ad65137344679b24fdccd1

You can find the result of the test in your current working directory.

By default the report result will be collected by the default ooni collector and the addresses of test helpers will be obtained from the default bouncer.

You may also specify your own collector or bouncer with the options -c and -b.

ooniprobe submits reports to oonib report collectors through Tor to a hidden service endpoint. By default, ooniprobe uses the installed system Tor, but can also be configured to launch Tor (see the advanced.start_tor option in ooniprobe.conf), and ooniprobe supports bridges (and obfsproxy bridges, if obfsproxy is installed). The tor.bridges option in ooniprobe.conf sets the path to a file that should contain a set of "bridge" lines (of the same format as used in torrc, and as returned by https://bridges.torproject.org). If obfsproxy bridges are to be used, the path to the obfsproxy binary must be configured. See option advanced.obfsproxy_binary, in ooniprobe.conf.

Install the latest version of obfsproxy for your platform.

Download Obfsproxy: https://www.torproject.org/projects/obfsproxy.html.en

If your distribution supports capabilities you can avoid needing to run OONI as root:

setcap cap_net_admin,cap_net_raw+eip /path/to/your/virtualenv's/python2

You can report bugs and issues you find with ooni-probe on The Tor Project issue tracker filing them under the "Ooni" component: https://trac.torproject.org/projects/tor/newticket?component=Ooni.

You can either register an account or use the group account "cypherpunks" with password "writecode".

You can download the code for ooniprobe from the following git repository:

git clone https://git.torproject.org/ooni-probe.git

It is also viewable on the web via: https://gitweb.torproject.org/ooni-probe.git.

You should then submit patches for review as pull requests to this github repository:

https://github.com/TheTorProject/ooni-probe

Read this article to learn how to create a pull request on github (https://help.github.com/articles/creating-a-pull-request).

If you prefer not to use github (or don't have an account), you may also submit patches as attachments to tickets.

Be sure to format the patch (given that you are working on a feature branch that is different from master) with:

git format-patch master --stdout > my_first_ooniprobe.patch

On Debian based systems a development environment can be setup as follows: (prerequisites include build essentials, python-dev, and tor; for tor see https://www.torproject.org/docs/debian.html.en):

sudo apt-get install python-pip python-virtualenv virtualenv
sudo apt-get install libgeoip-dev libffi-dev libdumbnet-dev libssl-dev libpcap-dev
git clone https://github.com/TheTorProject/ooni-probe
cd ooni-probe
virtualenv venv

virtualenv venv will create a folder in the current directory which will contain the Python executable files, and a copy of the pip library which you can use to install other packages. To begin using the virtual environment, it needs to be activated:

source venv/bin/activate pip install -r requirements.txt pip install -r requirements-dev.txt python setup.py install ooniprobe -s # if all went well, lists available tests
