OPNsense ISO does not boot! – How to Fix

Matthew 0 Comments

Recently, I have begun to pay more attention to my “Home Lab” as I strive to deepen my knowledge of the digital world.  One of the first things I was looking to do was to strengthen my network protection.  Like most folks, I have my internet provider’s modem/router as the only protection for my network.  So to fix this, I was looking into open-source solutions.  One of these solutions was OPNsense.

I had just received my FIREBAT Mini PC (pictured above), which had dual NIC cards and wanted to implement a strong firewall. I had heard a lot about OPNsense online, and did my research into a few of the top choices. …

Samba Based Active Directory on Ubuntu 22.04

Preface

I have been waiting for a long time to write this post.  In order to test this out, I needed to upgrade my home lab.  I had a VM machine running XCP-NG (I tried Proxmox, it’s just not the same), but it had an old dual core Intel and 8GB of ram, so not much I could do with other than host a good single VM… which is pointless, the server might as well be the function of that single VM.  So recently I was able to upgrade my main system to a Ryzen 5 5600X with a new mobo, RAM, and PSU, so I figured I would use my old Ryzen 5 1600X in the server. …

I moved my web server from VestaCP to HestiaCP and here is why.

Matthew 0 Comments

I recently took on the task of updating my webserver. The decision to do this was mainly because my web server’s operating system was nearing end of life. For those who know, CentOS 7 is the last of it’s kind, a stable enterprise OS based off of Redhat. With full release updates ending at the end of 2020 and security updates till 2024, I decided to jump ship… to Ubuntu.

Wait… What?… Ubuntu? Yes… Ubuntu (Ick, I hate myself for even saying it…)

Now do not get me wrong, Ubuntu is great, for those who are hobbyists. But for stability and enterprise applications, RedHat has been the leading OS, and hence CentOS (Except the Stream version) was also stable.…

[ FIX ] Unable to SSH into TNAS after update? TOS 4.2.28

Matthew 14 Comments

If you are like me, you use your TerraMaster NAS proficiently. By this I mean you use its full capabilities like SSH and SCP. But sadly the TerraMaster has changed their policy with the latest update.

With the latest version, 4.2.28-220119172 they enabled a lot of cool features, one being PAM, which blocks a user if they login with a bad password more than 3 times. However they enabled a feature I am not too fond of: SSH is not limited only to the Admin account. This means that if you had other users who logged into SSH, after the update, after attempting to login into an account other than admin, after a few tries you till get this message:

There is a fix… not official, and I could not find it in the forums… In fact TerraMaster’s
official stance is “Admin only”.…

Resetting Lost Root Password in Ubuntu when “single” fails.

Background Story (skip)

Quite a few times a year I head out to my best friend Eric’s place back in Ontario. We’ve known each other for the better part of our lives as we met in high school.  One of the passions we share is the Linux operating system, although different ends of the spectrum.  Eric is more into Ubuntu, and he runs it for his work and personal servers, as well as his desktop.  I on the other hand prefer Red Hat based systems, working on servers running Red Hat or CentOS, and have extensively used Fedora as a workstation for my work (although my home PC is still Windows based), and most recently I did switch to Zorin Pro (Ubuntu derivative) and currently use Arch Linux for my workstation for professional use.…

Installing epel-release in CentOS 8 and Oracle Linux 8 – The EASY Way

Matthew 1 Comment

TLDR:

Centos 8:

Oracle Linux 8:

NOTE: if you absolutely need to have “epel-release” installed due to dependancies on Oracle Linux – then use the rpm way:

 

 

The Whole Story

With the news late last year, that Redhat was killing off CentOS, there was a shockwave throughout the industry.  To those outside of the linux server environment, I am not sure you could comprehend the vast affect this will have. …

VestaCP offsite backup script

Matthew 0 Comments

I have always been an advocate for using a control panel when dealing with multi site hosting.  In my case I use VestaCP, which is a great, simple, free alternative to the big boys like Plesk and cPanel.  The only issue though, is space for backups.  On the server I normally have 3 to 5 days backed up, which is great, however if you find out your site had been hacked 7 days ago, all your backups on the server are tainted.  This happened to me a few years back, and one of my sites was hacked for almost a month before I found out.…

Creating a Local LAN with Zerotier

https://www.youtube.com/watch?v=Af758HL6VkA

I have been meaning to create a video about this for some time.  I am a tech fanatic, and when a better solution than Hamachi crossed my path, I was instantly indulging myself with its vast capabilities.  Zerotier is an amazing application.  It can be used to create a Local LAN so that gamers can play legacy titles like Warcraft III and the like, but it can also be “privatized” giving you full control over who has access to your network.  I have tested it on Windows and Linux, and use several personally created networks to play games with my friends back in Ontario, as well as administer my web servers, and lock down SSH to use only the internal network.…

Ansible: reboot and wait for response

Matthew 2 Comments

With my new job title of Linux System Administrator (more correctly “Administrateur Systèmes Linux“), there are some new things I have had to learn. One is the wonderful world of Ansible.

However, there is one thing that plagued me, rebooting the system and having it wait to run the next command. This is important for patching up a server then making sure everything came back up alright.

After scouring the web and trying out every post I found. I found a post that I was able to piece together other’s response to get a valid, working, solution.

Thank you to gvenka008c and andyhky who’s answers were what i needed to piece together the correct metod.…
