I2P Federation and Accessability¶
This guide is going to focus on the Akkoma federation aspect. The actual installation is neatly explained in the official documentation, and more likely to remain up-to-date. It might be added to this guide if there will be a need for that.
We're going to use I2PD for its lightweightness over the official client. Follow the documentation according to your distro: https://i2pd.readthedocs.io/en/latest/user-guide/install/#installing
How to run it: https://i2pd.readthedocs.io/en/latest/user-guide/run/
I2P Federation¶
There are 2 ways to go about this. One using the config, and one using external software (fedproxy). The external software works better so far.
Using the Config¶
Warning: So far, everytime I followed this way of federating using I2P, the rest of my federation stopped working. I'm leaving this here in case it will help with making it work.
Assuming you're running in prod, cd to your Akkoma folder and append the following to config/prod.secret.exs:
config :pleroma, :http, proxy_url: {:socks5, :localhost, 4447}
su akkoma
MIX_ENV=prod mix deps.get
MIX_ENV=prod mix ecto.migrate
exit
systemctl stop i2pd.service --no-block
systemctl start i2pd.service
You can change the socks proxy port in /etc/i2pd/i2pd.conf.
Using Fedproxy¶
Fedproxy passes through clearnet requests direct to where they are going. It doesn't force anything over Tor.
To use fedproxy you'll need to install Golang.
apt install golang
echo "export GOPATH=/home/ren/.go" >> ~/.bashrc
go get -u github.com/majestrate/fedproxy$
cp $(GOPATH)/bin/fedproxy /usr/local/bin/fedproxy
fedproxy 127.0.0.1:2000 127.0.0.1:4447
127.0.0.1:9050 to that command.
You'll also need to modify your Akkoma config.
Assuming you're running in prod, cd to your Akkoma folder and append the following to config/prod.secret.exs:
config :pleroma, :http, proxy_url: {:socks5, :localhost, 2000}
su akkoma
MIX_ENV=prod mix deps.get
MIX_ENV=prod mix ecto.migrate
exit
systemctl stop i2pd.service --no-block
systemctl start i2pd.service
You can change the socks proxy port in /etc/i2pd/i2pd.conf.
I2P Instance Access¶
Make your instance accessible using I2P.
Add the following to your I2PD config /etc/i2pd/tunnels.conf:
[akkoma]
type = http
host = 127.0.0.1
port = 14447
keys = akkoma.dat
systemctl stop i2pd.service --no-block
systemctl start i2pd.service
Now you'll have to find your address.
To do that you can download and use I2PD tools.[^1]
Or you'll need to access your web-console on localhost:7070.
If you don't have a GUI, you'll have to SSH tunnel into it like this:
ssh -L 7070:127.0.0.1:7070 user@ip -p port.
Now you can access it at localhost:7070.
Go to I2P tunnels page. Look for Server tunnels and you will see an address that ends with .b32.i2p next to "akkoma".
This is your site's address.
I2P-only Instance¶
If creating an I2P-only instance, open config/prod.secret.exs and under "config :pleroma, Pleroma.Web.Endpoint," edit "https" and "port: 443" to the following:
url: [host: "i2paddress", scheme: "http", port: 80],
Existing Instance (Clearnet Instance)¶
If not an I2P-only instance, add the nginx config below to your existing config at /etc/nginx/sites-enabled/akkoma.nginx.
And 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:
proxy_cache_path /tmp/akkoma-media-cache levels=1:2 keys_zone=akkoma_media_cache:10m max_size=10g inactive=720m use_temp_path=off;
# The above already exists in a clearnet instance's config.
# If not, add it.
server {
listen 127.0.0.1:14447;
server_name youri2paddress;
# Comment to enable logs
access_log /dev/null;
error_log /dev/null;
gzip_vary on;
gzip_proxied any;
gzip_comp_level 6;
gzip_buffers 16 8k;
gzip_http_version 1.1;
gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript application/activity+json application/atom+xml;
client_max_body_size 16m;
location / {
add_header X-XSS-Protection "0";
add_header X-Permitted-Cross-Domain-Policies none;
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;
add_header Referrer-Policy same-origin;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_pass http://localhost:4000;
client_max_body_size 16m;
}
location /proxy {
proxy_cache akkoma_media_cache;
proxy_cache_lock on;
proxy_ignore_client_abort on;
proxy_pass http://localhost:4000;
}
}
systemctl stop i2pd.service --no-block
systemctl start i2pd.service
You should now be able to both access your instance using I2P and federate with other I2P instances!

Possible Issues¶
Will be added when encountered.
