Homelab nâng cấp Proxmox/Docker gặp lỗi: sau cập nhật, các share bị mất truy cập, WebUI không thể kết nối. Thử tham số "optional=1" để snapshot nhưng gặp sự cố. PiHole với NGINX SSL cũng không hoạt động dù trước ổn định. Cần hỗ trợ từ cộng đồng! #Homelab #Proxmox #Docker #TrueNAS #PiHole #Linux #TechIssue #VănHóaMaker #CôngNghệ #KỹThuật #Upgrader #SysAdmin

In this blog post, I describe a bit how was my introduction to self-hosting, which is essentially a practice to host websites or services (like e-mail, file sharing, dedicated game servers, etc) in my own servers so I can have better control over data, privacy and computing infrastructure to potentially save costs and improve my computing skills:

Mise à jour ⚙️ réussie vers Mastodon v4.5.3 !
En tant qu'administrateur système sous Linux, j'apprécie toujours quand la mise à jour se passe sans accroc. Merci Docker de m'épargner le RAILS_ENV=production bundle exec rails assets:precompile ! 😅
🚀 Le Fédivers continue de tourner !
2.5 Admins 277: Battering RAM
The Crucial brand of consumer SSDs and RAM is going away, AMD and Intel memory encryption can be bypassed with cheap hardware, more AI buffoonery, and monitoring users’ usage on a network.
We're live!

I can’t believe how fast this semester went. Teaching Linux Administration at #JCCC has been one of the highlights of my year.
Watching students go from “what’s a terminal?” to confidently managing services, firewalls, accounts, and networks never gets old.
Huge shoutout to my students — thanks for showing up, asking great questions, and pushing yourselves. Can’t wait to do it again.

🔍 USB over IP Architecture Explained
Modern USB over IP systems follow a clear layered design: the USB Server handles device virtualization, the Client manages session forwarding, and the Protocol layer ensures reliable data transport. With optimized latency control, smart compression, and USB QoS, it supports dongles, instruments, storage devices, and more—securely and efficiently across networks.

I'm trying out this new thing on my server called "don't have Apache consistently crash every 5-10 minutes after restarting"
Ya know, just for shits and giggles
Customer complained that two of his systems were shutting down at random times. Not hang, not halt, just shutdown nicely. Hardware was replaced once already (not my call, before I was involved).
First thing I checked, /var/log/messages. Lots of stack traces, but at other times. "Linux version", yups, it was shutdown nicely.
Then I saw these two innocent lines:
2025-11-28T04:34:27 localhost auditd: Audit daemon is low on disk space for logging
2025-11-28T04:34:28 localhost auditd: The audit daemon is now halting the system
I knew that the machines were running auditd, but I had never looked further than that as it was non-enforcing. Checking auditd.conf, it says:
admin_space_left_action = halt
I checked this file from many other systems, and they're all set to "email" instead of "halt", except for the latest release of software.
And that is how I found out that PD had implemented the CIS Linux Benchmark Security Recommendations!
As usual: "We didn't think that it would cause any problems."
i revived and updated my 2007 thinkpad R61i, which hadn't been used in years. it's running arch linux and xfce. it developed hardware issues while shelved: intermittently unresponsive keys, nonworking battery, and unreliable optical drive. i had been thinking of setting up an environment for light web work on this low-end, low-res laptop. but it's so heavy, slow, and hot that might just be time to recycle it.
A new Admin Update landed in my inbox. It included the interestingly-titled article "Fishing with Remora" - https://www.admin-magazine.com/Articles/Fishing-with-Remora?utm_source=Mastodon
This immediately brought a Gary Larson cartoon… and, in a way, it is totally appropriate. Image source in alt text.
