TrueNAS UGREEN DXP4800 Plus Status LED Guide

UGREEN DXP4800 Plus TrueNAS Status LED Guide

20240609_035951642_iOS

The following is a quick guide on getting basic status LED functionality working with TrueNAS running on the UGREEN DXP4800 Plus. Theoretically, it should work on all models (with some small revisions to the script), but I only have a DXP4800 Plus. :)

This guide is for cron job that runs a script to update the LEDs every couple minutes, but I'm sure the following can be modified for blinky LEDs as well.

Steps:

Debian 13 trixie upgrade

Debian 13

Caution Upgrading from Debian 12 to Debian 13 on machines with mdadm has intermittently failed for me; symptom is that grub EFI is not up to date and system boots into BIOS. Root cause under investigation; it might not be related to mdadm.

To start, read the official release notes.

If your install fits into "vanilla Debian plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Debian 13 "trixie" from Debian 12 "bookworm" can be helpful. 3rd-party repos are handled with a find command.

Note upgrade is only supported from Debian 12 to Debian 13. If you are on Debian 11, upgrade to Debian 12 first. Then once on Debian 12, you can upgrade to Debian 13.

Humble bundle book bundles - download all books at once
/*
After purchasing a humble book bundle, go to your download page for that bundle.
Open a console window for the page and paste in the below javascript
this fork downloads all formats and does so without using jquery (since that didnt work for me)
note that if you are in chrome, chrome will not download the pdfs for you by default, to fix this
type “about:plugins” in the address bar and disable chrome's pdf viewer

Export TOTP tokens from Authy

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.
