VyOS: Getting Your Feet Wet

Goals For VyOS to be a viable replacement for my typical OpenBSD deployments, it must … Pffft. The goals were defined in a previous post … so let’s just get on with it, shall we? First Step Hints tab or question mark (?) provides command completion / hints enter configuration mode with the configure command after describing changes, use commit to make the changes live after changes are live, the save command will update the boot configuration exit configuration mode with the exit command NAT Outbound NAT NOTE: translation address can be specified; the use of masquerade results in usage of the primary address of the interface.

VyOS on a Serial Console

The Hardware I went scrounging for no-longer-used equipment I could play with, and found a couple of firewall appliances from yesteryear, originally used at two customer sites before being replaced with something a bit faster. At a previous job, I used several units just like these to implement a mesh-type network between 3 sites over ipsec. With OpenBSD, of course. These are neat little boxes with zero moving parts - they boot off CF cards, and their entire case is one big heatsink.

VyOS ... is it Vyable?

See what I did there? Yeah, I know. Pretty lame … Quick History I’ve been providing networking services for quite a while now. It all started with Data Generic’s Generic Barracks in the early 80’s, which was my 24-hour BBS running on the venerable Commodore 64. Over the past few decades I’ve leveraged a bunch of other technologies and products to provide networking services for customers. This includes Bay/Nortel/Juniper/ADTRAN/Cisco/NetWare/Microsoft/Linux and pretty much all the BSD flavors.

Well, that was fun. Our 2010 Chevy Traverse decided it didn’t want to play. 100 miles from home. At 9PM. In the dark. Worse, my wife was driving - and she was alone. You know, 100 miles from home. At 9PM. In the dark. Her description made it sound like the battery was at fault. Thankfully, we had extended family nearby and a quick jumpstart helped to get her on her way home safely.

Twinkle, twinkle

Just a quick data point … I had planned a 24-hour fast (not a big deal - skip meals between the last dinner and the next). In a moment of weakness last night I downed a bit of chips. Processed carbs - not the best choice. Not the worst, but … ok, fine - probably the worst. At any rate, at about the 18-hour mark, though I had not yet felt hunger or anything else, my eyesight started going wonky.

I'm Not Fast

During a bit of research on type 2 diabetes, I came across a book by Jason Fung, MD, titled The Obesity Code: Unlocking the Secrets of Weight Loss. I purchased the audiobook and listened on the way to/from work. Surprisingly, I actually enjoyed the book. The narrator did a great job. The book was engaging, funny at times, and written on my level. The author gave what amounted to a history lesson - describing how and why our diets have changed over the years, and what we have learned along the way.

Moore's Law

Way back in the 60’s and 70’s, a fellow named Gordon Moore posited that computer processor complexity would double every two years. That is not precisely what he predicted (I have simplified it somewhat), and he amended this a few times since. But the idea that most of us take away from Moore’s Law is that computer speed/capacity/capability doubles every couple of years. And for the most part, this has turned out to be true.
