About me 🐧🐧🐧

My name is Lennart, I thought I would put together this little site for myself and others to let them know I am still in the game, or trying to be, it is a work in progress 🤩. I have been working in the IT industry since 1994, when I got my CNE, I did start rather late in this endeavor but it has been very rewarding and I just love working, and tinkering with computers in general, Linux to be more specific, I have always built my own computers since my first one in 1994, a i386 DX40, I have used multiple OS's, like Windows, Mac OSX, gentoo, ArchLinux, libranet, Debian, Redhat, Fedora, and now since 2011 Arch based distros, I can say with certainty, Linux/Arch is my absolute favorite. For sure there are challenges and that is the great thing about Linux, you actually have to use your brain to figure things out. That, in my opinion, is the greatest appeal of Linux to me. No one wants to be a drone..... 🤣

My interests are in no particual order, Linux, Cyber Security, hacking (Figuring out how things work...), Networking, and technology in general.

What I am doing now?

Below is what I am focused on at the moment! 🐧🐧🐧

Health, family and (education).
PAUSED, indefinitely; Linux, Cyber Security, Security+, CySA+, Pen+, CEH, & technology.
Health is the most important thing, I had surgery in 2022, and since then my life has been in turmoil, so much pain; in my arms and neck, and not being able to focus on anything do to that, dizzy, and a whole bunch of other health problems....so to anyone that needs a neck fusion, DON'T do it, it destroyed my health.

My distro of choice! 🐧🐧🐧

I have been using Arch based distros since 2011, Arch Linux is my goto now and it has been for a while.

I use i3wm as my desktop, and also on my laptop. This is a tiling window manager, it is in my opinion the best one out there for people that want a specific workflow, it is easy to use and configure. My browser choice, I am a bit torn as I like Qutebrowser a lot, but for somethings it is not very friendly, so I mostly use brave, for the day to day and qutebrowser for everything else. As I also used Mac's once, one utility I missed on ArchLinux was "Dash" it is a great helper tool for any tech person, and "Yes", there is a linux version which is call Zeal, a very cool program, everyone should use it. I use beyond grep ack to find things, this helps a lot if you are looking through logs everyday. File manager is ranger, as it supports, with a hack viewing images in the console.

Shell - zsh - Terminal - st

Zsh has been my shell for a while, and I use the zsh-pure-prompt, it is clean, fast and has some great features.

My terminal of choice is st, small lightweight and very good, I did user rxvt for a long time

Cool Stuff

Here is some cool stuff I have found to make things easier using the terminal, use aliases/functions, there are so many options that can be made and it will make your life more productive. For example, if you are into pentesting, set up some aliases/functions, use zsh-pentest as a custom plugin, if you do not have oh-my-zsh, just source it from your .zshrc, and the same with quiver, awesome tools that someone have taken great care in creating for you. Shoutout to Steve Mcilwain for Quiver, just an awesome tool for Kali Linux. If you do have oh-my-zsh there are some really cool plugin`s, like nmap, git, archlinux, systemd, etc, check it out for your self.

Cyber Security & Scam Awareness Resources 🐧🐧🐧

In today’s hyper-connected world, protecting oneself online is no longer an optional technical skill, but a fundamental necessity for personal safety. As we migrate more of our lives into the digital realm—managing bank accounts, healthcare records, shopping, and social interactions via the internet—we leave behind a vast trail of sensitive information known as a digital footprint. Cybercriminals utilize increasingly sophisticated methods, such as phishing, identity theft, and malware, to exploit vulnerabilities in this data. A single successful breach can lead to devastating consequences, ranging from direct financial loss and unauthorized credit card charges to the much more complex and long-lasting trauma of identity theft and the exposure of deeply personal communications.

Beyond the immediate risk of financial ruin, online protection is essential for maintaining privacy and autonomy. In an era where information is permanent and easily searchable, failing to secure your digital presence can lead to lasting damage to your reputation and professional life. Data scraped from social media or leaked through insecure accounts can be used by bad actors for stalking, harassment, or even social engineering attacks against your friends and family. Therefore, practicing good digital hygiene—such as using strong, unique passwords, enabling multi-factor authentication, and staying vigilant against suspicious links—is a critical responsibility that safeguards not only your own assets but also the security of the broader digital community.

Sites to help you stay informed and protect yourself and others online.
