Nord: an unofficial NordVPN client

DEPRECATION NOTICE: This repository will no longer be actively worked on now that NordVPN has an official Linux client: https://support.nordvpn.com/Connectivity/Linux/

Overview

Nord is a client for interacting with the NordVPN service.

At its core is a high-level Python API for interacting both with the web service provided by NordVPN, and for connecting to VPN servers using OpenVPN.

Nord also contains components that expose this API as a command line tool, and (soon) as a web service and frontend.

Licence

Nord is licensed under the terms of the GNU GPLv3. See the LICENSE file for details.

Installation

pip install nord

Usage

Run nord --help for the full usage instructions.

Connect to a specific NordVPN server:

nord connect -u my_user -p my_password us893

Connect to any NordVPN server in a given country:

nord connect -u my_user -p my_password US

Serve a web app that allows you to select the country to which you wish to connect:

nord web -u my_user -p my_password

You can also supply your password from a file using the -f flag. The special value - means "read from stdin". This is particularly useful when your password is stored in a utility such as pass:

pass nordvpn_password | nord connect -u my_user -f - us893

Prerequesites

GNU/Linux system
Python 3.6
openvpn
sudo

nord contains many Linux-isms (e.g. using the sudo program to obtain root access) so it will certainly not work on Windows, it may possibly work on OSX and *BSD, but support for these platforms is not a goal.

Most recent versions of popular GNU/Linux distributions (with the exception of Debian) have both an OpenVPN client and Python 3.6 in their official repositories. Debian users will have to take additional steps to get a Python 3.6 installation.

Ubuntu 16.10 and newer

Ubuntu comes with sudo already installed, so we just need to install Python and openVPN:

sudo apt-get install python3.6 openvpn

Fedora 26 and newer

Fedora comes with sudo already installed, so we just need to install Python and openVPN:

sudo dnf install python36 openvpn

Arch Linux

Run the following as root:

pacman -S sudo python openvpn

Then configure sudo by following the Arch wiki to give privileges to the user that nord will be running as.

Debian

First run the following as root to install the openVPN client and sudo from the Debian repositories:

apt install sudo openvpn

Then configure sudo by following the Debian wiki to give privileges to the user that nord will be running as.

There are a couple of options for installing Python3.6 on Debian:

Installing from the unstable repositories
Installing from source (easier than you might think

Both of these methods are explained in top-rated answers to this stackexchange question.

Developing

You will need Python 3.6 and Yarn (for the web components).

git clone https://github.com/jbweston/nord
cd nord
virtualenv -p python3.6
source venv/bin/activate
pip install -e .[dev]
yarn install

Periodically check your code with the linter:

pylint nord

Web components

When developing the web frontend you can execute the following command to run an auto-reloading web server:

yarn dev
