I have been on this sub and playing around with selfhosting for almost two years now but I feel like I’ve barely scratched the surface.
I often feel inadequate when I see people on this sub discussing what I consider to be advanced networking terms and technologies, especially when discussing remote access.
Will getting a certification like Network+ help me feel more comfortable managing my homelab?
If not, can someone recommend any resources I should look into to get good at being my own sysadmin?
It’s entirely up to you. I did have a bunch of such certs, but none of them were actually useful for real-world setups; the knowledge I used for self-hosting came from me mucking around on the internet and reading RFCs and instruction manuals.
