Using the ESP8266 RTOS SDK on Linux

By -

The following procedure shows how to use Espressif's Real-Time Operating System Software Development Kit for ESP8266 microcontrollers on Debian-based Linux distributions.

==========

1. INSTALLATION

1.1. Update package indexes and install the prerequisites.

user@host: $ sudo apt-get update
user@host: $ sudo apt-get install bison libbison-dev
user@host: $ sudo apt-get install cmake
user@host: $ sudo apt-get install flex libfl-dev libfl2
user@host: $ sudo apt-get install git
user@host: $ sudo apt-get install gperf
user@host: $ sudo apt-get install libncurses-dev
user@host: $ sudo apt-get install python3 python3-dev python3-pip python3-venv python3-wheel

1.2. Clone the repository from GitHub. This will download to a directory with the same name.

user@host: $ mkdir esp
user@host: $ cd esp
user@host: $ git clone --recursive https://github.com/espressif/ESP8266_RTOS_SDK.git

1.3. Install the Python packages required by the ESP8266 Internet-of-Things Development Framework.

user@host: $ cd ESP8266_RTOS_SDK
user@host: $ python -m pip install --user -r requirements.txt

1.4. Install the ESP8266 IDF toolchain.

user@host: $ ./install.sh

1.5. Temporarily add the ESP8266 IDF toolchain to the shell path.

user@host: $ . ./export.sh
or
user@host: $ source ./export.sh

1.6. Verify if the toolchain has been added to the shell path.

user@host: $ echo $PATH

2. TESTING

2.1. Once the toolchain is on the shell path, go to the examples provided by the SDK.

user@host: $ cd examples/get-started/hello_world

2.2. Configure the IDF settings for the project.

user@host: $ make menuconfig

2.2.1. Use the arrow keys to highlight menu items.
2.2.2. Choose [ Save ] to accept the current settings.
2.2.3. Choose [ Exit ] to leave the menu.

2.3. Remove old build files, if any.

user@host: $ make clean

2.4. Build the ESP8266 project binaries.

user@host: $ make all

2.5. Flash the binaries to the ESP8266 microcontroller.

user@host: $ make flash

Enabling HTTPS in Home Assistant

By -
Image
The following procedure activates HTTPS for the Home Assistant server. The secure protocol uses TLS/SSL certificates to encrypt the data transferred between user and server. Although it is possible to make this home automation system, whether in  Linux or  FreeBSD , accessible over the Internet, Home Assistant is usually operated within private networks, either physical or virtual. In this case, self-signed certificates may be acceptable to use and quicker to deploy. ========== 1. Log in as the system account. 1.1. Linux, with $HOME "bin" included in $PATH (-i) of system account (-u). user@host: $ sudo -i -u homeassistant 1.2. FreeBSD, coming from "root" superuser. root@host: # su - homeassistant 2. Go to the Home Assistant configuration directory. user@host: $ cd ~/.homeassistant 3. Make a directory for SSL certificates. user@host: $ mkdir ssl 4. Ensure that only the system account and members of its group can access the directory. user@host: $ chmod 7

Configuring the FreeBSD Firewall with IPFW

By -
Image
IPFW is one of several firewalls included in FreeBSD by default. It has a command-line tool to handle the policies for incoming and outgoing connections. In the configurations discussed here, network connections "from any to any" are deliberately avoided to prevent potential bounce attacks from happening, if the server is not intended to act as a router. Instead, a request/respond or incoming/outgoing rule pair is adopted to direct the flow of network traffic. The main objective is to set up IPFW to block unauthorized remote access to unsecured ports on the server. But if attackers manage to break in through a vulnerability on some programs running on authorized incoming ports, the outgoing restrictions will prevent massive data exfiltration, stopping intruders dead in their tracks. A similar approach can be done on Debian-based Linux distributions using UFW . ========== 1. STRICT CONFIGURATION 1.1. Create a custom shell script for IPFW commands. root@host: #  ee /etc/myip

Running Home Assistant on FreeBSD Servers

By -
Image
Home Assistant is an open-source home automation system powered by Python, primarily intended to run on single-board computers like the Raspberry Pi, with Linux as the host operating system. The following procedure shows how to run Home Assistant Core on FreeBSD servers, on either physical or virtual machines. ========== 1. PREPARING THE SERVER 1.1. Update the package list and upgrade the existing packages. root@host: # pkg update && pkg upgrade -y 1.2. Install Python and other required packages. root@host: # pkg install python38 py38-sqlite3 openssl autoconf libffi rust 1.3. Create a system account with disabled login (-w no), a dedicated home directory (-m), and some informational text (-c comment). root@host: #  pw useradd homeassistant -w no -m -c "Home Assistant" 1.3.1. If groups for hardware input/output are present, append the system account. Else, skip this step for now. root@host: #  pw groupmod gpio -m homeassistant root@host: #  pw groupmod i2c -m homeassis
