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?
CompTIA is very high level, general, and basic. You’ll learn far more by doing than studying for CompTIA. Those certs are only useful to get yourself in the door for entry level positions at orgs.
