Good place to start, I think. Still, nothing beats hands-on. It’s useful to build a small server-based network at home. taht way, you can experiment and get immediate results - one way or the other - as you learn.
Probably will do that - I’ve got enough hardware to put something together. My problem’s mostly (I think) the terminology and getting a grounding. I’m pretty good technically and like self study.
I did just check the local comm colleges. HaHa.Auto mechanic, boat repair, fishing, carpentry, EMT, firefighter, etc.
