A simple mesh network communications app powered by the Reticulum Network Stack.
NOTE: micron format parsing is still in development, some pages may not render or work correctly at all.
You can download the latest version for Windows, Mac and Linux from the releases page.
Alternatively, you can download the source and run it manually from a command line.
See the "How to use it?" section below on how to do this.
Once you've downloaded, installed and launched Reticulum MeshChat, there's a few things you need to do in order to start communicating with other people on the network.
Create an Identity
On the Reticulum Network, anyone can have any number of Identities. You may opt to use your real name, or you may decide to be completely anonymous. The choice is yours.
A Reticulum Identity is a public/private key-pair. You control the private key used to generate destination addresses, encrypt content and prove receipt of data with unforgeable delivery acknowledgements.
Your public key is shared with the network when you send an announce, and allows others on the network to automatically discover a route to a destination you control.
At this time, Reticulum MeshChat generates a new Identity the first time you launch it. A future update will allow you to create and manage multiple identities.
For now, if you want to change, or reset your identity, you can access the identity file at ~/.reticulum-meshchat/identity
.
Configure your Display Name
The next thing you should do, is set a display name. Your display name is what everyone else on the network will see when looking for someone to communicate with from the Peers list.
You can do this in the My Identity
section in the bottom left corner. Enter a new display name, and then press Save
.
Send an Announce
When using the Reticulum Network, in order to be contactable, you need to send an Announce
. You can send an announce as often, or as infrequently as you like.
Sending an announce allows other peers on the network to discover the next-hop across the network their packets should take to arrive at a destination that your identity controls.
If you never send an announce, you will be invisible and no one will ever be able to send anything to you.
When you move across the network, and change entrypoints, such as moving from your home WiFi network, to plugging in to an Ethernet port in a local library or even climbing a mountain and using an RNode over LoRa radio, other peers on the network will only know the previous path to your destinations.
To allow them to discover the new path their packets should take to reach you, you should send an announce.
Discover Peers and start sending messages
In the Reticulum Network, you can control an unlimited number of destination addresses. One of these can be an LXMF delivery address.
Your Reticulum Identity allows you to have an LXMF address. Think of an LXMF address as your very own, secure, end-to-end encrypted, unspoofable, email address routed over a mesh network.
When someone else on the network announces themselves (more specifically, their LXMF address), they will show up in the Peers tab.
You can click on any of these discovered peers to open a messaging interface. From here, you can send text messages, files and inline images. If they respond, their messages will show up there too.
As well as being able to announce your LXMF address and discover others, Reticulum MeshChat can also discover Nomad Network nodes hosted by other users. From the Nodes tab, you are free to explore pages and download files they may be publicly sharing on the network.
A future update is planned to allow you to host your own Node and share pages and files with other peers on the network. For now, you could use the official Nomad Network client to do this.
Remember, in order to connect with other peers or nodes, they must announce on the network. So don't forget to announce if you want to be discovered!
Configuring additional Network Interfaces
TODO: this section is yet to be written. For now, you can check out the official documentation for configuring interfaces in the Reticulum config file. This file is located at
~/.reticulum/config
It is recommended that you download a standalone application.
If you don't want to, or a release is unavailable for your device, you will need to;
meshchat.py
.# clone repo
git clone https://github.com/liamcottle/reticulum-meshchat
cd reticulum-meshchat
# install nodejs deps
# if you want to build electron binaries, remove "--omit=dev"
npm install --omit=dev
# build frontend vue components
npm run build-frontend
# install python deps
pip install -r requirements.txt
# run meshchat
python meshchat.py
NOTE: You should now be able to access the web interface at http://localhost:8000
For a full list of command line options, you can run;
python meshchat.py --help
usage: meshchat.py [-h] [--host [HOST]] [--port [PORT]] [--headless] [--identity-file IDENTITY_FILE] [--identity-base64 IDENTITY_BASE64] [--generate-identity-file GENERATE_IDENTITY_FILE] [--generate-identity-base64]
[--reticulum-config-dir RETICULUM_CONFIG_DIR] [--storage-dir STORAGE_DIR]
ReticulumMeshChat
options:
-h, --help show this help message and exit
--host [HOST] The address the web server should listen on.
--port [PORT] The port the web server should listen on.
--headless Web browser will not automatically launch when this flag is passed.
--identity-file IDENTITY_FILE
Path to a Reticulum Identity file to use as your LXMF address.
--identity-base64 IDENTITY_BASE64
A base64 encoded Reticulum Identity to use as your LXMF address.
--generate-identity-file GENERATE_IDENTITY_FILE
Generates and saves a new Reticulum Identity to the provided file path and then exits.
--generate-identity-base64
Outputs a randomly generated Reticulum Identity as base64 and then exits.
--reticulum-config-dir RETICULUM_CONFIG_DIR
Path to a Reticulum config directory for the RNS stack to use (e.g: ~/.reticulum)
--storage-dir STORAGE_DIR
Path to a directory for storing databases and config files (default: ./storage)
It is possible to run on Android from source, using Termux. You will need to install a few extra dependencies and make a change to requirements.txt
.
pkg install git
pkg install rust
pkg install python-pip
pkg install binutils
pkg install build-essential
You should now be able to follow the how to use it instructions above.
Before running pip install -r requirements.txt
, you will need to comment out the cx_freeze
dependency. It failed to build on my Android tablet, and is not actually required for running from source.
nano requirements.txt
Ensure the cx_freeze
line is updated to #cx_freeze
Note: Building wheel for cryptography may take a while on Android.
Once MeshChat is running via Termux, open your favourite Android web browser, and navigate to http://localhost:8000
Note: The default
AutoInterface
may not work on your Android device. You will need to configure another interface such asTCPClientInterface
.
The first time you run this application, a new Reticulum identity is generated and saved to storage/identity
.
If you want to use an existing identity;
storage/identity
with another identity file.To use a custom identity file, provide the --identity-file
argument followed by the path to your custom identity file.
python meshchat.py --identity-file ./custom_identity_file
If you would like to generate a new identity, you can use the rnid utility provided by Reticulum.
rnid --generate ./new_identity_file
If you don't have access to the rnid
command, you can use the following:
python meshchat.py --generate-identity-file ./new_identity_file
Alternatively, you can provide a base64 encoded private key, like so;
python meshchat.py --identity-base64 "GCN6mMhVemdNIK/fw97C1zvU17qjQPFTXRBotVckeGmoOwQIF8VOjXwNNem3CUOJZCQQpJuc/4U94VSsC39Phw=="
NOTE: this is a randomly generated identity for example purposes. Do not use it, it has been leaked!
Reticulum MeshChat can be run from source via a command line, as explained above, or as a standalone application.
To run as a standalone application, we need to compile the python script and dependencies to an executable with cxfreeze and then build an Electron app which includes a bundled browser that can interact with the compiled python executable.
This allows for the entire application to be run by double clicking a single file without the need for a user to manually install python, nor run any commands in a command line application.
To build a .exe
when running on Windows or a .dmg
when running on a Mac, run the following;
pip install -r requirements.txt
npm install
npm run dist
Note: cxfreeze only supports building an executable for the current platform. You will need a Mac to build for Mac, and a Windows PC to build for Windows.
Once completed, you should have a .exe
or a .dmg
in the dist
folder.
I normally run the following commands to work on the project locally.
Install dependencies
pip install -r requirements.txt
npm install
Build and run Electron App
npm run electron
or; Build and run MeshChat Server
npm run build-frontend
python3 meshchat.py --headless
I build the vite app everytime without hot reload, since MeshChat expects everything over its own port, not the vite server port. I will attempt to fix this in the future.
