No one is immune from this

Next hardware reset and automatic reorientation for Voyager 2 is October 15th. Yes the device automatically resets itself about four to five times a year. Communications are expected to be reestablished then.
- In the meantime, they're going to shout at it.
- That's good news! I was about to ask whether they have some absolute software recovery procedure and glad they do!
- That's great to know. This post made me weirdly depressed and was a bad way to start the morning lol.
- Almost like real engineers planned for such an event!

Someone ran 'systemctl restart networking' while SSH'd into the probe.
- Unrelated but I've been wondering this for years: What's your avatar from and why do so many people across the web have that exact same one?
  
  No idea, I found it somewhere a decade ago and have been using it. I think I’ve only seen someone with it like one other time. 🤷🏻‍♂️
  
  I remember it used to be popular in gaming groups and some music around 2008-2012 and a lot of variations of the same gas mask character were made
  
  The guy I know who uses gasmasks everywhere does it because it's a fetish.

sudo rm -rf --no-preserve-root /
- starman is not in the sudoers file.
  This incident will be reported.
  
  Oh no, Linus Torvalds is gonna call me again

  oops...
- sudo rm -rf /*

Wikipedia states: "In July 2023, communication with Voyager 2 was lost when flight control pointed its antenna away from Earth, moving it by 2 degrees away from Earth. The NASA dish antenna in Canberra is being used to search for the space probe and will be used to saturate its location with commands to re-align the probe's antenna in an attempt to re-establish the radio link. If NASA fails to contact the probe, it is expected that an automatic system on Voyager 2 will direct its dish toward Earth in October 2023."
- So essentially someone probably wanted to move it one way and it moved the other. It should automatically reposition itself in contact with NASA in 2 months. It's amazing the foresight we had in 1977 to write in all sorts of catch-alls... In 2 months we'll get back in contact with the probe and it will have its own place, hanging out with aliens.
- Great that they included these automatic hardware resets. Way to go if your computer will never see a human or human-made thing ever again

V2 be like: "WHAT did you say about my mother? F... you, Earth man."
Mission control: "Dude you don't have a mother it was a typo. Dude. Talk to me."
seen
Mission control: "Dude."
seen
Mission control: "C'mon man."
This message could not be sent. V2 may have blocked your number

Sounds like it's a recoverable error (if the scientists can't do it the spacecraft has an automated process that'll kick in in October.) Still, I can't imagine what that must feel like.

  Probably a lot like the person responsible for dropping the NOAA-19 satellite.
- I imagine they feel bad. Not really bad, like a loved one died, but pretty bad, like a passion they worked really hard for just fizzled out.

You just need to reboot it manually
- Just press and hold the power button smh

That's why your color your production windows red.

When you ufw enable but forgot to whitelist port 22

Hello IT, have you tried turning it off and on again?

Probably played with the firewall settings and accidentally disabled port 22... It sucked when I did that

There's no going into the office to fix this one...

Looks like someone removed the ssh keys

Wow! Wondering how the guy is being treated who sent the wrong command. I did it once at my work and people were acting really Weird. In my defense, I never really liked the job.
- I bet you don't simply send random commands to the probe. There are likely a dozen of people who need to approve literally every keystroke.
  
  This. And even then there should be procedures in place to essentially make it impossible to send the wrong inputs.
  It's like when an intern accidentally drops the production database. It's not the interns fault for sending the wrong command. It's the managements fault for not restricting access in the first place.
  
  "I'm gonna click approve without looking because the tons of people before / after me must have / will review it."
  
  🤦‍♂️

Patching recent ssh vulnerabilities I see

Tfw you conf t and shut a management port down on accident and don't have a backup console connection

UP ARROW!!

FUC-

Have you tried turning it off and on again?

No biggie just get someone to mount the files system and edit the ssh file 😌

Must have been an intern.

iptables -P INPUT DROP

Awww, what a shame though. This probe was doing some really cool stuff, it's kinda iconic in my head.
- It should be ok. It's due to self-reset its orientation on October 15, they put measures in place for if they accidentally lost contact.
  I would still be besides myself if I had made that error though.
- Yeah all jokes aside this is a actually pretty big loss for the scientific community. Assuming it's completely unrecoverable. We blew our chance to actually measure the conditions in interstellar space and see if it lines up with our theories, and another probe is not only not planned for the foreseeable future by any space agency, it will also take decades to get to where Voyager 2 is now.
  Edit: Nevermind, see the other comment. It's likely not permanently lost!
  
  Also haven't we been gathering interstellar readings for a while now?

Wow, I just read the wiki. It has a 64 Megabyte tape storage, so after it realigns the antenna they can receive the data they've missed. Pretty state of the art for 1977. I wonder how they shielded it from radiation. The fuel source of the reactor lasts probably until 2026. After that, it'll travel as a brick, most likely long after humans rm -rf'd

Sounds like those two need to go to couples therapy.
