darkfi/bin/dnet

dnet

A simple tui to explore darkfi p2p network topology. Connects to nodes on the darkfi network using RPC and displays the following info:

1. Every inbound, outbound and manual connections.
2. Events such as peer discovery, new connections, disconnections etc.
3. All messages per connection.

All darkfi node types are supported, i.e. darkfid, darkirc, taud, fud, etc.

dnet is based on the design-pattern Model, View, Controller. We create a logical seperation between the underlying data structure or Model; the ui rendering aspect which is the View; and the Controller or game engine that makes everything run.

Run

Using a venv

Dnet requires Python 3.14. Make sure Python is installed and on the latest version.

Depending on your setup you may need to install a virtual environment for Python. Do so as follows:

% python -m venv python-env
% source python-env/bin/activate

Then install the requirements:

% pip install -r requirements.txt

Run dnet:

% python dnet

You will need to reactivate the venv in your current terminal session each time you use dnet as follows:

% source python-env/bin/activate

Without a venv

If you don't require a venv, install the requirements and run dnet as follows:

% pip install -r requirements.txt
% python dnet

Config

On first run, dnet will create a config file in the config directory specific to your operating system.

To use dnet you will need to open the config file and modify it to display the individual nodes you want to inspect. By node we mean daemon such as darkirc, darkfid, taud etc. Each node in the dnet config has the following parameters:

• name: An arbitary string (whatever you want to call your node, e.g. darkirc).
• host: The network host, set to localhost by default, but you can replace this with hostnames or external IP addresses.
• port: The rpc_listen port of the node you want to connect to.
• type: Specify whether it is a NORMAL or a LILITH node. (If you don't know what this means, such stick with NORMAL).

Next, make sure that this line is commented in the config file of the node you are trying to connect to:

## Disabled RPC methods
#rpc_disabled_methods = ["p2p.get_info"]

If necessary, restart the node to apply the change.

Usage

Navigate up and down using the arrow keys. Scroll the message log using PageUp and PageDown. Type q to quit.

Logging

dnet creates a log file in bin/dnet/dnet.log. To see json data and other debug info, tail the file like so:

tail -f dnet.log
