First of all, thank you for your videos. I learn a lot from it. Second, your main page doesn’t have secure certificate if you just type learnlinux.tv. I believe it should force ssl.
Now to a real question.
I understood that ssh key is best way to remote manage a server. Let’s say I have 4 homelab VM server and I am managing all from my personal PC. Can I copy public and private key and move to new PC if I reinstall OS. Because what if I disable password authentication and only way was my old pc to remote manage those 4 homelab VM or cloud VM on linode for instance.
I would appreciate your help. Thank you.
