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! 🐧🐧🐧

  1. Health, family and (education).
  2. PAUSED, indefinitely; Linux, Cyber Security, Security+, CySA+, Pen+, CEH, & technology.
  3. 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 wezterm, 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.
