Oracle Linux Host Firewall Config

The default firewall configuration of Oracle Linux in the OCI environment basically denies everything. To enable traffic of any kind these following commands are needed.

sudo systemctl status firewalld
sudo firewall-cmd --list-all
sudo firewall-cmd --zone=public
sudo firewall-cmd --zone=public --add-port=5201/tcp --permanent
sudo firewall-cmd --zone=public --add-port=5201/udp --permanent

WARNING: orphaned

This worked for me. It will probably work for you with minor touches if you insist. After I ran this for a while I didn't like how unreliable Duplicati was with the actual work of backing up and I began to investigate Duplicacy instead. I will leave this here for a year or so because it will probably remain more or less valid for that long and I did spend a lot of time putting it together to just thwack it because it's not useful to me. YMMV. GL. GG.

Duplicati on TrueNAS

This is a note on installing Duplicati, a free Backup server into a TrueNAS Core jail.

1 - Set up and configure the Jail

In TrueNAS create a Jail running the latest FreeBSD image available (13.2-RELEASE-p4). I am calling this jail instance backup

HADS

https://github.com/sinedied/hads

A simple, markdown-based wiki written in Node. It does just enough for what I need and not much more.

Installed on TrueNas in a FreeBSD jail. HADS lives in /mnt/HADS/

Prep & Install

• Create DNS A record for home pointing to 10.39.6.46
• pkg install setsid npm sudo

import RPi.GPIO as GPIO # Import Raspberry Pi GPIO library

GPIO.setwarnings(False) # Ignore warning for now
GPIO.setmode(GPIO.BCM)  # Use Broadcom GPIO numbers
                        # not BOARD for pin numbers
# This example is based on using the buttons in this hardware:
# https://learn.adafruit.com/adafruit-2-2-pitft-hat-320-240-primary-display-for-raspberry-pi/
Button1 = 17 # Board pin 11
Button2 = 22 # Board pin 15
Button3 = 23 # Board pin 23

on the raspberry pi with the camera attached:

libcamera-vid -t 0 --listen -o tcp://0.0.0.0:8888

on the client (my mac laptop)

ffplay tcp://10.39.6.55:8888 -vf "setpts=N/30" -fflags nobuffer -flags low_delay -framedrop

Notes:

Obviously, change the IP address in the client command to the IP or hostname of the raspberry pi. The picture quality isn't super great, but when setting up the frame for a time-lapse shot this gives a quick view of what's in the picture and may help with initial focus.
