There are a few dependencies which we recommend you get from your distribution's archives.
sudo apt-get install build-essential python-dev python-setuptools openssl
You will need a Tor binary on your system. For complete instructions, see also:
https://www.torproject.org/docs/tor-doc-unix.html.en
https://www.torproject.org/docs/rpms.html.en
If you've already got Tor, or plan to compile it yourself from source, great! You can skip this step. Otherwise, if you're installing Tor (or reinstalling), you'll want to make sure to get our keyring package in Debian:
echo "deb http://deb.torproject.org/torproject.org wheezy main" | \
sudo tee -a /etc/apt/sources.list
gpg --keyserver keys.gnupg.net --recv EE8CBC9E886DDD89
gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo apt-key add -
sudo apt-get update
sudo apt-get install deb.torproject.org-keyring tor tor-geoipdb
We recommend using the Pip>=1.3.0 because it included several important security and privacy related patches:
- It forces the use of HTTPS for PyPI.
- and checks package hash sums before installation, with support for hashes more collision-resistant than MD5.
The least painful way (that we know of) to install a newer Pip is to use Pip's get-pip script:
# Grab the get-pip installer to make sure we have pip>=1.3.0
curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py
sudo python ./get-pip.py ## pip (>=1.3.0) is recommended for security reasons
# And make sure we're actually using the newer one:
sudo update-alternatives --install /usr/bin/pip pip /usr/local/bin/pip 0
We recommend that you use a python virtualenv. The recommended commands for setting up this up and installing are:
sudo pip install --upgrade virtualenv virtualenvwrapper
# Setup the virtualenv directory:
export WORKON_HOME=~/.virtualenvs && mkdir -p $WORKON_HOME
source /usr/local/bin/virtualenvwrapper.sh
# Clone ooni-backend:
git clone https://github.com/TheTorProject/ooni-backend.git && cd ooni-backend
# Create the virtualenv for ooni-backend...
mkvirtualenv -a $PWD --unzip-setuptools --setuptools --no-site-packages oonib
# ...and install ooni-backend (sudo is not necessary since we're in a virtualenv):
pip install -r requirements.txt --use-mirrors
# Note: it is important that you install the requirements before you run
# the setup.py script. If you fail to do so they will be downloaded over
# plaintext.
python setup.py install
Copy the example config file to oonib.conf.
cp oonib.conf.example oonib.conf
Then edit your configuration to fit your needs. The fields you should probably
end up changing are report_dir (the public web server directory where you
would like ooni-probe clients to be able to submit reports to, for example, if
the clients should submit POSTs to https://abcdef0123456789.onion/report then
this would simply be 'report') and tor_datadir (where you would
like the spawned Tor process to keep its data). If you compiled Tor yourself,
you'll likely want to specify it for the tor_binary option.
If you want to use the HTTPS test helper, you will need to create a certificate:
openssl genrsa -des3 -out private.key 4096
openssl req -new -key private.key -out server.csr
cp private.key private.key.org
# Remove passphrase from key
openssl rsa -in private.key.org -out private.key
openssl x509 -req -days 365 -in server.csr -signkey private.key -out certificate.crt
rm private.key.org
rm server.csr
If you decide to put your certificate and key somewhere else, don't forget to
update oonib.conf options helpers.ssl.private_key and helpers.ssl.certificate !
The following iptables commands will map connections on low ports to those bound by oonib:
# Map port 80 to config.helpers['http-return-json-headers'].port (default: 57001)
iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j REDIRECT --to-ports 57001
# Map port 443 to config.helpers.ssl.port (default: 57006)
iptables -t nat -A PREROUTING -p tcp -m tcp --dport 443 -j REDIRECT --to-ports 57006
# Map port 53 udp to config.helpers.dns.udp_port (default: 57004)
iptables -t nat -A PREROUTING -p tcp -m udp --dport 53 -j REDIRECT --tor-ports
# Map port 53 tcp to config.helpers.dns.tcp_port (default: 57005)
iptables -t nat -A PREROUTING -p tcp -m tcp --dport 53 -j REDIRECT --tor-ports
WARNING: provides no anonymity! Use only if you know what you are doing! Tor2webmode will improve the performance of the collector Hidden Service by discarding server-side anonymity.
You will need to build Tor from source. At the time of writing, the latest stable Tor is tor-0.2.3.25. You should use the most recent stable Tor.
Example:
git clone https://git.torproject.org/tor.git
git checkout tor-0.2.3.25
git verify-tag -v tor-0.2.3.25
You should see:

Build Tor with enable-tor2web-mode
./autogen.sh ; ./configure --enable-tor2web-mode ; make
Copy the tor binary from src/or/tor somewhere and set the corresponding options in oonib.conf.
To launch oonib on startup, you may want to use supervisord (www.supervisord.org) The following supervisord config will use the virtual environment in /home/ooni/venv_oonib and start oonib on boot:
[program:oonib]
command=/home/ooni/venv_oonib/bin/python /home/ooni/ooni-probe/bin/oonib
autostart=true
user=oonib
directory=/home/oonib/
To test the deployment of oonib you may use vagrant.
Once installed you will be able to install oonib in the virtual machine via:
vagrant up
