Epicyon, meaning "more than a dog". Largest of the Borophaginae which lived in North America 20-5 million years ago.
Epicyon is a modern ActivityPub compliant server implementing both S2S and C2S protocols and sutable for installation on single board computers. It includes features such as moderation tools, post expiry, content warnings, image descriptions, news feed and perimeter defense against adversaries. It contains no javascript and uses HTML+CSS with a Python backend.

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 /etc directory. It's not essential that it be installed there, and it could be in any other preferred directory.
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
Environment=USER=epicyon
Environment=PYTHONUNBUFFERED=true
Restart=always
StandardError=syslog
[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;
server_name YOUR_DOMAIN;
ssl_stapling off;
ssl_stapling_verify off;
ssl on;
ssl_certificate /etc/letsencrypt/live/YOUR_DOMAIN/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/YOUR_DOMAIN/privkey.pem;
#ssl_dhparam /etc/ssl/certs/YOUR_DOMAIN.dhparam;
ssl_session_cache builtin:1000 shared:SSL:10m;
ssl_session_timeout 60m;
ssl_prefer_server_ciphers on;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA:ECDHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES256-SHA:ECDHE-ECDSA-DES-CBC3-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS';

}
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.
certbot certonly -n --server https://acme-v02.api.letsencrypt.org/directory --standalone -d YOUR_DOMAIN --renew-by-default --agree-tos --email YOUR_EMAIL
And restart the web server:
systemctl restart nginx
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.
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.
Adding Themes
If you want to add a new theme then open theme.py
and add the theme name to the list within getThemesList
. Add a function with the name setTheme[YourThemeName]
. Have a look at the other themes to get an idea of how to set the colors and fonts.
Add the name of your theme to the translations files.
Within the img
directory add a default profile background image called image_[YourThemeName].png
and a banner image banner_[YourThemeName].png
. Because the banner image will be reloaded occasionally it should be small - preferably kilobytes rather than megabytes.
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 values within your setTheme
function.
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
