Easy Onion Federation (Tor)¶
Tor can free people from the necessity of a domain, in addition to helping protect their privacy. As Akkoma's goal is to empower the people and let as many as possible host an instance with as little resources as possible, the ability to host an instance with a small, cheap computer like a Raspberry Pi along with Tor, would be a great way to achieve that. In addition, federating with such instances will also help furthering that goal.
This is a guide to show you how it can be easily done.
This guide assumes you already got Akkoma working, and that it's running on the default port 4000. This guide also assumes you're using Nginx as the reverse proxy.
To install Tor on Debian / Ubuntu:
apt -yq install tor
WARNING: Onion instances not using a Tor version supporting V3 addresses will not be able to federate with you.
Create the hidden service for your Akkoma instance in
/etc/tor/torrc, with an HTTP tunnel:
HiddenServiceDir /var/lib/tor/akkoma_hidden_service/ HiddenServicePort 80 127.0.0.1:8099 HiddenServiceVersion 3 # Remove if Tor version is below 0.3 ( tor --version ) HTTPTunnelPort 9080
systemctl restart email@example.com
Next, edit your Akkoma config.
If running in prod, navigate to your Akkoma directory, edit
and append this line:
config :pleroma, :http, proxy_url: "http://localhost:9080"
su akkoma MIX_ENV=prod mix deps.get MIX_ENV=prod mix ecto.migrate exit
systemctl restart akkoma
Tor Instance Access¶
Make your instance accessible using Tor.
If creating a Tor-only instance, open
config/prod.secret.exs and under "config :pleroma, Akkoma.Web.Endpoint," edit "https" and "port: 443" to the following:
url: [host: "onionaddress", scheme: "http", port: 80],
Existing Instance (Clearnet Instance)¶
If not a Tor-only instance,
add the nginx config below to your existing config at
For both cases, disable CSP in Akkoma's config (STS is disabled by default) so you can define those yourself separately from the clearnet (if your instance is also on the clearnet).
Copy the following into the
config/prod.secret.exs in your Akkoma folder (/home/akkoma/akkoma/):
config :pleroma, :http_security, enabled: false
Use this as the Nginx config:
systemctl reload nginx
You should now be able to both access your instance using Tor and federate with other Tor instances!
- In Debian, make sure your hidden service folder
/var/lib/tor/akkoma_hidden_service/and its contents, has debian-tor as both owner and group by usingIf it's not, run:
ls -la /var/lib/tor/
chown -R debian-tor:debian-tor /var/lib/tor/akkoma_hidden_service/
- Make sure only the owner has only read and write permissions.
If not, run:
chmod -R 600 /var/lib/tor/akkoma_hidden_service/
- If you have trouble logging in to the Mastodon Frontend when using Tor, use the Tor Browser Bundle.
