Getting Started Fast
|
|
********************
|
|
|
|
The best way to get started with the Reticulum Network Stack depends on what
|
|
you want to do. This guide will outline sensible starting paths for different
|
|
scenarios.
|
|
|
|
|
|
Try Using a Reticulum-based Program
|
|
=============================================
|
|
If you simply want to try using a program built with Reticulum, you can take
|
|
a look at `Nomad Network <https://github.com/markqvist/nomadnet>`_, which
|
|
provides a complete encrypted communications suite built with Reticulum.
|
|
|
|

|
|
:target: _images/nomadnet_3.png
|
|
|
|
`Nomad Network <https://github.com/markqvist/nomadnet>`_ is a user-facing client
|
|
for the messaging and information-sharing protocol
|
|
`LXMF <https://github.com/markqvist/lxmf>`_, another project built with Reticulum.
|
|
|
|
You can install Nomad Network via pip:
|
|
|
|
.. code::
|
|
|
|
# Install ...
|
|
pip3 install nomadnet
|
|
|
|
# ... and run
|
|
nomadnet
|
|
|
|
**Please Note**: If this is the very first time you use pip to install a program
|
|
on your system, you might need to reboot your system for your program to become
|
|
available. If you get a "command not found" error or similar when running the
|
|
program, reboot your system and try again.
|
|
|
|
|
|
Using the Included Utilities
|
|
=============================================
|
|
Reticulum comes with a range of included utilities that make it easier to
|
|
manage your network, check connectivity and make Reticulum available to other
|
|
programs on your system.
|
|
|
|
You can use ``rnsd`` to run Reticulum as a background or foreground service,
|
|
and the ``rnstatus``, ``rnpath`` and ``rnprobe`` utilities to view and query
|
|
network status and connectivity.
|
|
|
|
To learn more about these utility programs, have a look at the
|
|
:ref:`Using Reticulum on Your System<using-main>` chapter of this manual.
|
|
|
|
|
|
Creating a Network With Reticulum
|
|
=============================================
|
|
To create a network, you will need to specify one or more *interfaces* for
|
|
Reticulum to use. This is done in the Reticulum configuration file, which by
|
|
default is located at ``~/.reticulum/config``. You can edit this file by hand,
|
|
or use the interactive ``rnsconfig`` utility.
|
|
|
|
When Reticulum is started for the first time, it will create a default
|
|
configuration file, with one active interface. This default interface uses
|
|
your existing ethernet network (if there is one), and only allows you to
|
|
communicate with other Reticulum peers within your local broadcast domain.
|
|
|
|
To communicate further, you will have to add one or more interfaces. The default
|
|
configuration includes a number of examples, ranging from using TCP over the
|
|
internet, to LoRa and Packet Radio interfaces.
|
|
|
|
Possibly, the examples in the config file are enough to get you started. If
|
|
you want more information, you can read the :ref:`Building Networks<networks-main>`
|
|
and :ref:`Interfaces<interfaces-main>` chapters of this manual.
|
|
|
|
|
|
Develop a Program with Reticulum
|
|
===========================================
|
|
If you want to develop programs that use Reticulum, the easiest way to get
|
|
started is to install the latest release of Reticulum via pip:
|
|
|
|
.. code::
|
|
|
|
pip3 install rns
|
|
|
|
The above command will install Reticulum and dependencies, and you will be
|
|
ready to import and use RNS in your own programs. The next step will most
|
|
likely be to look at some :ref:`Example Programs<examples-main>`.
|
|
|
|
For extended functionality, you can install optional dependencies:
|
|
|
|
.. code::
|
|
|
|
pip3 install pyserial netifaces
|
|
|
|
|
|
Further information can be found in the :ref:`API Reference<api-main>`.
|
|
|
|
|
|
Participate in Reticulum Development
|
|
==============================================
|
|
If you want to participate in the development of Reticulum and associated
|
|
utilities, you'll want to get the latest source from GitHub. In that case,
|
|
don't use pip, but try this recipe:
|
|
|
|
.. code::
|
|
|
|
# Install dependencies
|
|
pip3 install cryptography pyserial netifaces
|
|
|
|
# Clone repository
|
|
git clone https://github.com/markqvist/Reticulum.git
|
|
|
|
# Move into Reticulum folder and symlink library to examples folder
|
|
cd Reticulum
|
|
ln -s ../RNS ./Examples/
|
|
|
|
# Run an example
|
|
python3 Examples/Echo.py -s
|
|
|
|
# Unless you've manually created a config file, Reticulum will do so now,
|
|
# and immediately exit. Make any necessary changes to the file:
|
|
nano ~/.reticulum/config
|
|
|
|
# ... and launch the example again.
|
|
python3 Examples/Echo.py -s
|
|
|
|
# You can now repeat the process on another computer,
|
|
# and run the same example with -h to get command line options.
|
|
python3 Examples/Echo.py -h
|
|
|
|
# Run the example in client mode to "ping" the server.
|
|
# Replace the hash below with the actual destination hash of your server.
|
|
python3 Examples/Echo.py 3e12fc71692f8ec47bc5
|
|
|
|
# Have a look at another example
|
|
python3 Examples/Filetransfer.py -h
|
|
|
|
When you have experimented with the basic examples, it's time to go read the
|
|
:ref:`Understanding Reticulum<understanding-main>` chapter.
|
|
|
|
|
|
Reticulum on ARM64
|
|
==============================================
|
|
On some architectures, including ARM64, not all dependencies have precompiled
|
|
binaries. On such systems, you will need to install ``python3-dev`` before
|
|
installing Reticulum or programs that depend on Reticulum.
|
|
|
|
.. code::
|
|
|
|
# Install Python and development packages
|
|
sudo apt update
|
|
sudo apt install python3 python3-pip python3-dev
|
|
|
|
# Install Reticulum
|
|
python3 -m pip install rns
|
|
|
|
|
|
Reticulum on Android
|
|
==============================================
|
|
Reticulum can be used on Android in different ways. The easiest way to get
|
|
started is using the `Termux app <https://termux.com/>`_, at the time of writing
|
|
available on `F-droid <https://f-droid.org>`_.
|
|
|
|
Termux is a terminal emulator and Linux environment for Android based devices,
|
|
which includes the ability to use many different programs and libraries,
|
|
including Reticulum.
|
|
|
|
Since the Python cryptography.io module does not offer pre-built wheels for
|
|
Android, the standard one-line install of Reticulum does not work on Android,
|
|
and a few extra commands are required.
|
|
|
|
From within Termux, execute the following:
|
|
|
|
.. code::
|
|
|
|
# First, make sure indexes and packages are up to date.
|
|
pkg update
|
|
pkg upgrade
|
|
|
|
# Then install dependencies for the cryptography library.
|
|
pkg install python build-essential openssl libffi rust
|
|
|
|
# Make sure pip is up to date, and install the wheel module.
|
|
pip3 install wheel pip --upgrade
|
|
|
|
# To allow the installer to build the cryptography module,
|
|
# we need to let it know what platform we are compiling for:
|
|
export CARGO_BUILD_TARGET="aarch64-linux-android"
|
|
|
|
# Start the install process for the cryptography module.
|
|
# Depending on your device, this can take several minutes,
|
|
# since the module must be compiled locally on your device.
|
|
pip3 install cryptography
|
|
|
|
# If the above installation succeeds, you can now install
|
|
# Reticulum and any related software
|
|
pip3 install rns
|
|
|
|
It is also possible to include Reticulum in apps compiled and distributed as
|
|
Android APKs. A detailed tutorial and example source code will be included
|
|
here at a later point.
