I’ve been a system engineer in and Windows environment for 17 years. My goal is to be a DevOps engineer by 2024. Your videos and books make learning Linux simple besides I love technology and have a passion for it. I really enjoy your content. Please keep the videos coming sir.

[Anthony-Webb]

What a great video! I thought I had a good routine for setting up servers, but man was I wrong.

Thanks so much, Jay!

[rnlvshe]

A year latter and the video still kicks ass ;~o

[davemeech]

This is amazing stuff. I'm going to be referencing this when starting my homelab projects for sure.

[brotaque]

Great video! One of the most valuable channels that I ever subscribed to.

[navidan]

What a great timing. I am about to build my first server and of course I'm going to install Linux on it. Just waiting for a motherboard, everything else already arrived.

[rayjaymor]

Your videos are so amazing, thank you Jay!

[model.citizen.ps]

Great video amigo! Keep up the good content 🤩

[altan_duman]

This is the only channel I keep checking.

To add a user in Debian I use adduser(8) or addgroup(8) instead of usermod(8) to add secondary group to an account, as that has less switch and easier to remember.

Usually one change configurations for the sshd by adding files into /etc/ssh/sshd_config.d/ direcotory instead of editing /etc/ssh/sshd_config.

[AdrianGoodyer]

Great video.
- Next steps would be to configure your firewall (ufw on Debian) and setup and VPN connections etc.
- then automating everything (e.g. via Ansible) for repeatable infrastructure

[GrindAlchemyNation]

Thank you for all you are doing sir! 💪🏾👽👌🏽

[AlbandAquino]

Again, when upgrading your packages, don't do it blindly. Read the list of upgraded packages.

If you see something you were not expecting, press "n". "Just like that." 😉

[VirendraBG]

I am your old subscriber.
Your all videos are gold mines.
👍🏻👌🏻

[wyfyj]

Love the new Intro. Don't remember if I said

[TheChrissutcliffe]

Nice Video :) This is my first time owning a VPS and viewing /var/log/auth.log was a little unnerving. I feel a little more confident now. Thanks.

[asdf]

Useful video! I will be going through this shortly once I finish building this 7900 (non-x) PC that I plan to put Mint Cinnamon on.

[johnnycoding]

Nice tutorial with very clear and detail introduced steps, would be even better with some basic firewall setup steps :D

[jojobobbubble]

Pretty solid video! Thanks much! Is there a concise guide for hardening a Linux Server you would recommend?

I've been a linux guy for over 20 years and I didn't know about copy-ssh-id.. I've been copy/pasting my RSA keys into ~/.ssh/authorized_keys like a dummy this entire time. I assume the command appends, so as not to remove existing keys, if so I'm gonna have to start using that!
