Epicyon, meaning "more than a dog". Largest of the Borophaginae which lived in North America 20-5 million years ago.

Epicyon is a fediverse server suitable for self-hosting a small number of accounts on low power systems.

Key features:

  • Open standards: HTML, CSS, ActivityPub S2S and C2S, RSS, CalDAV.
  • Supports common web browsers and shell browsers.
  • Will not drain your mobile or laptop battery.
  • Customisable themes. It doesn't have to look bland.
  • Emoji reactions.
  • Geospatial hashtags.
  • Does not require much RAM, either on server or client.
  • Suitable for installation on single board computers.
  • No timeline algorithms.
  • No javascript.
  • No database. Data stored as ordinary files.
  • No fashionable web frameworks. "Boring by design".
  • No blockchain garbage.
  • Written in Python, with few dependencies.
  • AGPL license, which big tech hates.

Epicyon is for people who are tired of big anything and just want to DIY their online social experience without much fuss or expense. Think water cooler discussions rather than shouting into the void, in which you're mainly just reading and responding to the posts of people that you're following.

Package Dependencies

You will need python version 3.7 or later.

On Arch/Parabola:

sudo pacman -S tor python-pip python-pysocks python-cryptography \
               imagemagick python-requests \
               perl-image-exiftool python-dateutil \
               certbot flake8 bandit
sudo pip3 install pyqrcode pypng

One package needs to be built manually from the Arch User Repository (AUR), since it is not included in the usual repositories.

su - epicyon
cd /tmp
git clone https://aur.archlinux.org/python-django-timezone-field.git
cd python-django-timezone-field.git
makepkg -sir
exit

Or on Debian:

sudo apt install -y \
    tor python3-socks imagemagick \
    python3-setuptools \
    python3-cryptography \
    python3-dateutil \
    python3-idna python3-requests \
    python3-django-timezone-field \
    libimage-exiftool-perl python3-flake8 \
    python3-pyqrcode python3-png python3-bandit \
    certbot nginx wget

Installation

In the most common case you'll be using systemd to set up a daemon to run the server.

The following instructions install Epicyon to the /opt directory. It's not essential that it be installed there, and it could be in any other preferred directory.

Clone the repo, or if you downloaded the tarball then extract it into the /opt directory.

cd /opt
git clone --depth 1 https://gitlab.com/bashrc2/epicyon

Add a dedicated user so that we don't have to run as root.

adduser --system --home=/opt/epicyon --group epicyon

Link news mirrors:

mkdir /var/www/YOUR_DOMAIN
mkdir -p /opt/epicyon/accounts/newsmirror
ln -s /opt/epicyon/accounts/newsmirror /var/www/YOUR_DOMAIN/newsmirror

Edit /etc/systemd/system/epicyon.service and add the following:

[Unit]
Description=epicyon
After=syslog.target
After=network.target

[Service]
Type=simple
User=epicyon
Group=epicyon
WorkingDirectory=/opt/epicyon
ExecStart=/usr/bin/python3 /opt/epicyon/epicyon.py --port 443 --proxy 7156 --domain YOUR_DOMAIN --registration open --log_login_failures
Environment=USER=epicyon
Environment=PYTHONUNBUFFERED=true
Environment=PYTHONIOENCODING=utf-8

PrivateDevices=true
PrivateIPC=true
MemoryDenyWriteExecute=true
NoNewPrivileges=true
LockPersonality=true
RestrictRealtime=true
RestrictSUIDSGID=true
RestrictNamespaces=true
SystemCallArchitectures=native

[Install]
WantedBy=multi-user.target

Here the server was installed to /opt/epicyon, but you can change that to wherever you installed it.

Then run the daemon:

systemctl enable epicyon
chown -R epicyon:epicyon /opt/epicyon
systemctl start epicyon

Check the status of the daemon with:

systemctl status epicyon

If it's not running then you can also look at the log:

journalctl -u epicyon

You'll also need to set up a web server configuration. For Nginx edit /etc/nginx/sites-available/YOUR_DOMAIN as follows:

server {
    listen 80;
    listen [::]:80;
    server_name YOUR_DOMAIN;
    access_log /dev/null;
    error_log /dev/null;
    client_max_body_size 31m;
    client_body_buffer_size 128k;

    index index.html;
    rewrite ^ https://$server_name$request_uri? permanent;
}

server {
    listen 443 ssl http2;
    server_name YOUR_DOMAIN;

    gzip on;
    gzip_disable "msie6";
    gzip_vary on;

    }
}

Changing your domain name as appropriate. Activate the configuration with:

ln -s /etc/nginx/sites-available/YOUR_DOMAIN /etc/nginx/sites-enabled/

Generate a LetsEncrypt certificate.

systemctl stop nginx
certbot certonly -n --server https://acme-v02.api.letsencrypt.org/directory --standalone -d YOUR_DOMAIN --renew-by-default --agree-tos --email YOUR_EMAIL
systemctl start nginx

And restart the web server:

systemctl restart nginx

If you need to use fail2ban then failed login attempts can be found in accounts/loginfailures.log.

If you are using the Caddy web server then see caddy.example.conf

Running Static Analysis

Static analysis can be run with:

./static_analysis

Running a security audit

To run a security audit:

./security_audit

Note that not all of the issues identified will necessarily be relevant to this project. Consider its output as a list of things which potentially can be investigated but usually will turn out not to be relevant.

Installing on Onion or i2p domains

If you don't have access to the clearnet, or prefer not to use it, then it's possible to run an Epicyon instance easily from your laptop. There are scripts within the deploy directory which can be used to install an instance on a Debian or Arch/Parabola operating system. With some modification of package names they could be also used with other distros.

Please be aware that such installations will not federate with ordinary fediverse instances on the clearnet, unless those instances have been specially modified to do so. But onion instances will federate with other onion instances and i2p instances with other i2p instances.

Custom Fonts

If you want to use a particular font then copy it into the fonts directory, rename it as custom.ttf/woff/woff2/otf and then restart the Epicyon daemon.

systemctl restart epicyon

Custom Favicon

If you want to use your own favicon then copy your favicon.ico file to the base directory where you installed Epicyon.

Changing Themes

When changing themes you may need to ensure that your nginx cache is cleared (/var/www/cache/*) and that your local browser cache is cleared for the site (Shift + Reload). Otherwise images and icons from the previous theme may remain.

Adding Themes

If you want to add a new theme then first add the name of your theme to the translations files.

Within the theme directory create a directory with the name of your theme and add icons and banners. As a quick way to begin you could copy the contents of theme/default, then edit the graphics. Keep the size of images as small as possible to avoid creating a laggy user interface.

On a running instance you can experiment with colors or fonts by editing epicyon.css and then reloading the web page. Once you are happy with the results then you can update the changed variable values within your theme/yourtheme/theme.json file.

Epicyon normally uses one set of CSS files whose variables are then altered per theme. If you want to use entirely bespoke CSS then copy epicyon-*.css into your theme directory and edit it to your requirements. This will be used rather than the default CSS files. Be warned that if you're maintaining the CSS files yourself then you may need to keep up with whatever changes are happening upstream, otherwise your user interface will break.

Running Unit Tests

To run the unit tests:

python3 epicyon.py --tests

To run the network tests. These simulate instances exchanging messages.

python3 epicyon.py --testsnetwork
