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 node with several serial port based interfaces, it can be
beneficial to use the fixed name device nodes 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 node name
assignment varies from one boot to another.
Run Reticulum as a 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=network.target
StartLimitIntervalSec=0
[Service]
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
