You will need python version 3.7 or later.
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
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
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.
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 --logLoginFailures 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:
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 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:
Running a security audit
To run a 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.
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
If you want to use your own favicon then copy your
favicon.ico file to the base directory where you installed Epicyon.
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.
If you want to add a new theme then first add the name of your theme to the translations files.
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
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
