Script for testing if interface works ok and restart some services after interface recovers from failure.
#!/bin/bash
# script for checking if specified interface is UP and properly connected to network (so ping can work)
# enter test ping address. IF ping fails it's marked by creation of file. When ping starts working again
# it restart few services (domoticz, mosquitto, samba) and docker containers (you need to specify your
# own containers IDs).
# script also write to syslog when the ping fail first time (when interface failed), and when recovered.
# crontab entry for running every 1min:
# * * * * * /root/restart-services.sh >/dev/null 2>&1

Preview monitor for Octoprint on Raspberry Pi and DSI screen

Pre-req.

  1. Raspberry Pi (2,3,4 ; 0 and 1 might be to weak... )
  2. Display - I used 5" DSI from BTT (BigTreeTech)
  3. Octoprint with mjpeg-streamer

Setup

  1. Burn latest RaspiOS (I used raspbian 11 bullseye 2022-04-04-raspios-bullseye-armhf-lite ) on SD,
  2. Create default user (pi) and enable ssh (fastes use headless method - need 2 files to drop on sd boot partition: userconf and ssh)
  3. Run raspi-config and enable kms driver (raspi-config will install some packages doing this): 8. -> A2. -> G2. , also set RaspiOS to console-autologin mode, don't reboot yet.
  4. Edit /boot/config.txt, find line with dtoverlay and vc4-kms... , change kms to fkms: dtoverlay=vc4-fkms-v3d - otherwise vlc won't work 😒 , now reboot,

Prereqs

  1. Burn raspios image on card - the one with desktop (no need to additional software) - tested using 2023-12-05-raspios-bookworm-arm64.img on RPi4 & RPi5.
  2. Install few additional packages to build a wayland plugin that hide cursor 
    sudo apt install libglibmm-2.4-dev libglm-dev libxml2-dev libpango1.0-dev libcairo2-dev wayfire-dev libwlroots-dev libwf-config-dev meson
  3. Clone github repo: https://github.com/saper-2/wayfire-plugins-extra , and compile plugins (but not install them)

git clone https://github.com/WayfireWM/wayfire-plugins-extra && cd wayfire-plugins-extra

Debian on HP T620 terminal - hints

Installation tips

I use only Debian and net-inst image to install linux, and I use text install 😄

  • When partitioning primary disk where will be Debian installed, create first partiton of size 256-512M as EFI System partition - this will set this partition as Bootable, and FileSystem=vfat .
  • Don't forget about swap partition if you have not much too much RAM (at least of size of RAM), I usually create 4-8GB as 2nd partition on disk.
  • You can optionally create partition for /boot that have about 1-2GB , FS=ext4,
  • Or just use whole disk as / , FileSystem=ext4 - I almost always choose this setup - it's the most optimal.
