Doubt grows with knowledge.
I was going to start a link log when I realized what I actually want is my own version of r/todayilearned with blackjack and hookers some sort of breadcrumbs to preserve my path to new findings.

Looking for ways to expose SSH behind NAT? Search no further!
Publish SSH server port of your laptop, which is behind NAT:
ssh any-username@ssh-j.com -N -R laptop-behind-nat:22:localhost:22
╭─╯ unique ╰─╮ │ device name ╭───╯ │destination│
│ namespace │ │ and port │ │address and│
│for your hosts│ ╰──────────────╯ │ port │
╰──────────────╯ ╰───────────╯
Connect to the published SSH:
ssh -J any-username@ssh-j.com laptop-behind-nat
↖
It's THAT easy!
Published hosts are bound to the username. Other usernames can't access them.
Pick a unique username (not root 😁) and get access to your devices anywhere!
Limits: 6 exposed services (ports) per username.make ☺It is rare in this world that the silly name us developers think up for a new project makes it into the final, public, product. We might name the company database Delaware (because that’s where all the companies are registered), but you can be sure by the time it hits production it will be CompanyMetadataDatastore. But rarely, when all the stars align and the boss is on vacation, one slips through the cracks.
Use active voice whenever possible. Passive voice can be used to describe the error condition.
Use past tense if an attempt to do something failed, but could perhaps succeed next time (perhaps after fixing some problem). Use present tense if the failure is certainly permanent.
