HELP: Setting up I2Pd on Raspberry Pi 4 (feddit.org)

Hey folks!

I just learned about I2P and already tested it successfully with I2Pd on my debian PC.

But I want to support the network 24/7 so I need to set it up on my raspberry pi 4 and I plan to use it from LAN.

So I installed it like described in the documentation for debian (https://docs.i2pd.website/en/latest/user-guide/install/#linux).

I changed my config via sudo nano /etc/i2pd/i2pd.conf and edited some things like this:

[http]
enabled = true
address = 0.0.0.0
port = 7070

[httpproxy]
enabled = true
address = 0.0.0.0
port = 4444

and I restarted with sudo systemctl restart i2pd

I am using the I2Pd-Firefox-Bundle and I changed the Firefox-settings (Settings -> Network Settings) to this:

(pointing to my raspberry pi)

.i2p-Sites are working well so far, but I am not able to open the webconsole with this configuration. I try to open it with http://192.168.178.26:7070/ but I only get host mismatch.

What am I doing wrong?

Thanks in advance!

Edit:

A solution has been found with nginx:

On the Pi:

sudo apt update
sudo apt install nginx

Followed by:

sudo nano /etc/nginx/sites-available/i2pd

Edit to:

server {
    listen 8080;
    server_name _;

    location / {
        proxy_pass http://127.0.0.1:7070/;
        proxy_set_header Host localhost;
    }
}

Enable the file:

sudo ln -s /etc/nginx/sites-available/i2pd /etc/nginx/sites-enabled/

Deleted the nginx-default-site

sudo rm /etc/nginx/sites-enabled/default

i2pd web interface doesn't like when you don't address it as localhost. Try http://localhost:7070/

Unlike curl 127.0.0.1:7070 (which gives a host mismatch as well) curl localhost:7070 is actually working, but sadly, only locally on the Pi itself :(.

I made a quick demo of an nginx server block that forwards like that, listening on :7071 of whereever you run nginx. It's completely untested so may have issues.

server {
  listen      7071;
  listen [::]:7071;
  
  location / {
    proxy_http_version 1.1;
    proxy_set_header  Host  localhost;
    proxy_pass http://<pi-ip>:7070;
  }
}

Thanks! I will take a look at it, when I'm home (I'm not that familiar with nginx).

I missed that you are using it remotely.
You can set up a proxy with nginx that changes the host parameter to localhost then connect to that.
Or you can for example use an addon that sends a custom Host value.

Fundamentally the hostname is just a freetext field you can fill however you want.
