Using Reticulum on Your System
|
|
******************************
|
|
|
|
Reticulum is not installed as a driver or kernel module, as one might expect
|
|
of a networking stack. Instead, Reticulum is distributed as a Python module.
|
|
This means that no special privileges are required to install or use it. It
|
|
is also very light-weight, and easy to transfer to and install on new systems.
|
|
Any program or application that uses Reticulum will automatically load and
|
|
initialise Reticulum when it starts.
|
|
|
|
In many cases, this approach is sufficient. When any program needs to use
|
|
Reticulum, it is loaded, initialised, interfaces are brought up, and the
|
|
program can now communicate over any Reticulum networks available. If another
|
|
program starts up and also wants access to the same Reticulum network, the
|
|
instance is simply shared. This works for any number of programs running
|
|
concurrently, and is very easy to use, but depending on your use case, there
|
|
are other options.
|
|
|
|
Included Utility Programs
|
|
-------------------------
|
|
|
|
If you often use Reticulum from several different programs, or simply want
|
|
Reticulum to stay available all the time, for example if you are hosting
|
|
a transport node, you might want to run Reticulum as a separate service that
|
|
other programs, applications and services can utilise.
|
|
|
|
The rnsd Utility
|
|
================
|
|
|
|
To do so is very easy. Simply run the included ``rnsd`` command. When ``rnsd``
|
|
is running, it will keep all configured interfaces open, handle transport if
|
|
it is enabled, and allow any other programs to immediately utilise the
|
|
Reticulum network it is configured for.
|
|
|
|
You can even run multiple instances of rnsd with different configurations on
|
|
the same system.
|
|
|
|
.. code:: text
|
|
|
|
# Install Reticulum
|
|
pip3 install rns
|
|
|
|
# Run rnsd
|
|
rnsd
|
|
|
|
.. code:: text
|
|
|
|
usage: rnsd [-h] [--config CONFIG] [-v] [-q] [--version]
|
|
|
|
Reticulum Network Stack Daemon
|
|
|
|
optional arguments:
|
|
-h, --help show this help message and exit
|
|
--config CONFIG path to alternative Reticulum config directory
|
|
-v, --verbose
|
|
-q, --quiet
|
|
--version show program's version number and exit
|
|
|
|
You can easily add ``rnsd`` as an always-on service by :ref:`configuring a service<using-systemd>`.
|
|
|
|
The rnstatus Utility
|
|
====================
|
|
|
|
Using the ``rnstatus`` utility, you can view the status of configured Reticulum
|
|
interfaces, similar to the ``ifconfig`` program.
|
|
|
|

The rnpath Utility
|
|
====================
|
|
|
|
With the ``rnpath`` utility, you can look up and view paths for
|
|
destinations on the Reticulum network.
|
|
|
|
.. code:: text
|
|
|
|
# Run rnpath
|
|
rnpath eca6f4e4dc26ae329e61
|
|
|
|
# Example output
|
|
Path found, destination <eca6f4e4dc26ae329e61> is 4 hops away via <56b115c30cd386cad69c> on TCPInterface[Testnet/frankfurt.rns.unsigned.io:4965]
|
|
|
|
.. code:: text
|
|
|
|
usage: rnpath.py [-h] [--config CONFIG] [--version] [-t] [-r] [-d] [-D] [-w seconds] [-v] [destination]
|
|
|
|
Reticulum Path Discovery Utility

|
|
|
positional arguments:
|
|
destination hexadecimal hash of the destination
|
|
|
|
optional arguments:
|
|
-h, --help show this help message and exit
|
|
--config CONFIG path to alternative Reticulum config directory
|
|
--version show program's version number and exit
|
|
-t, --table show all known paths
|
|
-r, --rates show announce rate info
|
|
-d, --drop remove the path to a destination
|
|
-D, --drop-announces drop all queued announces
|
|
-w seconds timeout before giving up
|
|
-v, --verbose
|
|
|
|
|
|
The rnprobe Utility
|
|
====================
|
|
|
|
The ``rnprobe`` utility lets you probe a destination for connectivity, similar
|
|
to the ``ping`` program. Please note that probes will only be answered if the
|
|
specified destination is configured to send proofs for received packets. Many
|
|
destinations will not have this option enabled, and will not be probable.
|
|
|
|
.. code:: text
|
|
|
|
# Run rnprobe
|
|
python3 -m RNS.Utilities.rnprobe example_utilities.echo.request 9382f334de63217a4278

|
Improving System Configuration
|
|
------------------------------
|
|
|
|
If you are setting up a system for permanent use with Reticulum, there is a
|
|
few system configuration changes that can make this easier to administrate.
|
|
These changes will be detailed here.
|
|
|
|
|
|
Fixed Serial Port Names
|
|
=======================
|
|
|
|
On a Reticulum instance with several serial port based interfaces, it can be
|
|
beneficial to use the fixed device names for the serial ports, instead
|
|
of the dynamically allocated shorthands such as ``/dev/ttyUSB0``. Under most
|
|
Debian-based distributions, including Ubuntu and Raspberry Pi OS, these nodes
|
|
can be found under ``/dev/serial/by-id``.
|
|
|
|
You can use such a device path directly in place of the numbered shorthands.
|
|
Here is an example of a packet radio TNC configured as such:
|
|
|
|
.. code:: text
|
|
|
|
[[Packet Radio KISS Interface]]
|
|
type = KISSInterface
|
|
interface_enabled = True
|
|
outgoing = true
|
|
port = /dev/serial/by-id/usb-FTDI_FT230X_Basic_UART_43891CKM-if00-port0
|
|
speed = 115200
|
|
databits = 8
|
|
parity = none
|
|
stopbits = 1
|
|
preamble = 150
|
|
txtail = 10
|
|
persistence = 200
|
|
slottime = 20
|
|
|
|
Using this methodology avoids potential naming mix-ups where physical devices
|
|
might be plugged and unplugged in different orders, or when device name
|
|
assignment varies from one boot to another.

|
|
Reticulum as a System Service
|
|
=============================
|
|
|
|
Instead of starting Reticulum manually, you can install ``rnsd`` as a system
|
|
service and have it start automatically at boot.
|
|
|
|
If you installed Reticulum with ``pip``, the ``rnsd`` program will most likely
|
|
be located in a user-local installation path only, which means ``systemd`` will not
|
|
be able to execute it. In this case, you can simply symlink the ``rnsd`` program
|
|
into a directory that is in systemd's path:
|
|
|
|
.. code:: text
|
|
|
|
sudo ln -s $(which rnsd) /usr/local/bin/
|
|
|
|
You can then create the service file ``/etc/systemd/system/rnsd.service`` with the
|
|
following content:
|
|
|
|
.. code:: text
|
|
|
|
[Unit]
|
|
Description=Reticulum Network Stack Daemon
|
|
After=multi-user.target
|
|
|
|
[Service]
|
|
# If you run Reticulum on WiFi devices,
|
|
# or other devices that need some extra
|
|
# time to initialise, you might want to
|
|
# add a short delay before Reticulum is
|
|
# started by systemd:
|
|
# ExecStartPre=/bin/sleep 10
|
|
Type=simple
|
|
Restart=always
|
|
RestartSec=3
|
|
User=USERNAMEHERE
|
|
ExecStart=rnsd --service
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
|
|
Be sure to replace ``USERNAMEHERE`` with the user you want to run ``rnsd`` as.
|
|
|
|
To manually start ``rnsd`` run:
|
|
|
|
.. code:: text
|
|
|
|
sudo systemctl start rnsd
|
|
|
|
If you want to automatically start ``rnsd`` at boot, run:
|
|
|
|
.. code:: text
|
|
|
|
sudo systemctl enable rnsd |
