Etebase - Encrypt Everything

An Etebase (EteSync 2.0) server so you can run your own.

Installation

Requirements

Etebase requires Python 3.7 or newer and has a few Python dependencies (listed in requirements.in/base.txt).

From source

Before installing the Etebase server make sure you install virtualenv (for Python 3):

  • Arch Linux: pacman -S python-virtualenv
  • Debian/Ubuntu: apt-get install python3-virtualenv
  • Mac/Windows (WSL)/Other Linux: install virtualenv or just skip the instructions mentioning virtualenv.

Then just clone the git repo and set up this app:

git clone https://github.com/etesync/server.git etebase

cd etebase

# Set up the environment and deps
virtualenv -p python3 .venv  # If doesn't work, try: virtualenv3 .venv
source .venv/bin/activate

pip install -r requirements.txt

Configuration

If you are familiar with Django you can just edit the [settings file](etebase_server/settings.py) according to the Django deployment checklist. If you are not, we also provide a simple [configuration file](etebase-server.ini.example) for easy deployment which you can use. To use the easy configuration file rename it to etebase-server.ini and place it either at the root of this repository or in /etc/etebase-server.

There is also a wikipage detailing this basic setup.

Some particular settings that should be edited are:

  • ALLOWED_HOSTS -- this is the list of host/domain names or addresses on which the app will be served. For example: etebase.example.com
  • DEBUG -- handy for debugging, set to False for production
  • MEDIA_ROOT -- the path to the directory that will hold user data.
  • SECRET_KEY -- an ephemeral secret used for various cryptographic signing and token generation purposes. See below for how default configuration of SECRET_KEY works for this project.

Now you can initialise our django app.

./manage.py migrate

And you are done! You can now run the debug server just to see everything works as expected by running:

uvicorn etebase_server.asgi:application --host 0.0.0.0 --port 8000

Using the debug server in production is not recommended, so please read the following section for a proper deployment.

Production deployment

There are more details about a proper production setup using uvicorn and Nginx in the wiki.

The webserver should also be configured to serve Etebase using TLS. A guide for doing so can be found in the wiki as well.

The Etebase server needs to be aware of the URL it's been served as, so make sure to forward the Host header to the server if using a reverse proxy. For example, you would need to use the following directive in nginx: proxy_set_header Host $host;.

Data locations and backups

The server stores user data in two different locations that need to be backed up:

  1. The database - how to backup depends on which database you use.
  2. The MEDIA_ROOT - the path where user data is stored.

Usage

Create yourself an admin user:

./manage.py createsuperuser

At this stage you need to create accounts to be used with the EteSync apps. To do that, please go to: www.your-etesync-install.com/admin and create a new user to be used with the service. No need to set a password, as Etebase uses a zero-knowledge proof for authentication, so the user will just create a password when creating the account from the apps.

After this user has been created, you can use any of the EteSync apps to signup (or login) with the same username and email in order to set up the account. The password used at that point will be used to setup the account. Don't forget to set your custom server address under "Advanced".

SECRET_KEY and secret.txt

The default configuration creates a file “secret.txt” in the project’s base directory, which is used as the value of the Django SECRET_KEY setting. You can revoke this key by deleting the secret.txt file and the next time the app is run, a new one will be generated. Make sure you keep the secret.txt file secret (e.g. don’t accidentally commit it to version control). However, backing it up is okay, and it makes it easier to restore the database to a new EteSync server, but it's not essential. If you want to change to a more secure system for storing secrets, edit etesync_server/settings.py and implement your own method for setting SECRET_KEY (remove the line where it uses the get_secret_from_file function). Read the Django docs for more information about the SECRET_KEY and its uses.

Updating

Updating from version 0.5.0 onwards

First, run git pull --rebase to update this repository. Then, inside the virtualenv:

  1. Run pip install -U -r requirements.txt to update the dependencies.
  2. Run python manage.py migrate to perform database migrations.

You can now restart the server.

Updating from version 0.5.0 or before

The 0.5.0 release marks the change to the EteSync 2.0 protocol. EteSync 2.0 accounts are substantially different to 1.0 accounts, and require additional upgrade steps. In addition, the servers are incompatible, so 0.5.0 requires a fresh installation.

Here are the update steps:

  1. Chose any of the the migration tools and make sure the underlying apps are up to date with all of your data. So for example, if you are using the Android client, make sure to sync before commencing.
  2. Install the 0.5.0 version to a new path (you can't reuse the same database).
  3. Run the 0.5.0 account and create the appropriate users as described in the installation/upgrade steps above.
  4. Run the migration tool to migrate all of your data.
  5. Add your new EteSync 2.0 accounts to all of your devices.

Testing

Docker images named etesync/test-server:<version> and :latest are available for testing etesync clients. This docker image starts a server on port 3735 that supports user signup (without email confirmation), is in debug mode (thus supporting the reset endpoint), and stores its data locally. It is in no way suitable for production usage, but is able to start up quickly and makes a good component of CI for etesync clients and users of those clients.
