This is a joke, I didn’t really lock myself out
good reason to take a day out, will tell it to my boss.
I try to remember to always open two SSH connections when altering iptables or the ssh config - just in case
i feel that. Hetzner support has a special place in my heart
Happened to me once. Had a little Pi at my parent’s house and that was a nice excuse to visit them.
Except when you get there and don’t want to talk or do all the meeting and greeting until you know the server still works.

Doing this is a right of passage.
Believe it or not, “rite” is the, uh, right, word here.
Messing up the spelling is a wrong of passage.
You have a right to pass once you’ve done this rite of passage.
Believe it or not, straight to jail
I don’t belief it.
Just breath!

this sounds like something chip from sales would do
It’s gray on the bottom.
Hello Derek you fucking idiot
Almost the same thing happened to me. I accidentally fucked up the internet connection in my home while in Japan, and I had to video call my mom to have her fix it. It was a pain for both of us, but thankfully it went rather smoothly. Thank you mom!
Do you mind explaining the details? I’m trying to learn as much as possible!
So I connected through ssh back home to fiddle with the router settings, and in the PPPoE settings (where you set a pair of username and password that your router sends to the ISP such that the ISP knows you and knows what IP to assign to you) I made a typo, and apparently that instantly killed the internet connection at home and also for me. I had to call my mom to instruct her to fix the typo in the username. TBH I don’t know that much about PPPoE either, I only do it so that the ISP assigns us the same IP address every time.
Most corporate network devices like Cisco will reset their config to the one written in memory when they lose power.
So in that case, just unplug and replug them to restore to previous config.
Just make sure you write your new config to memory or it will reset when there is ever a power failure.
I’ll always be grateful for the firewalls like OpenWRT that will automatically revert any changes if you don’t log back in after a few minutes (at least on the web interface). I’m not proud of how many times that’s saved me.
No connection, no hackers.
Before you make a change, do this in a screen-session:
sleep 300 && iptables-restore old_fw_rules.bak
permission denied
fuuuu
Found the debian user.
user permissions is a debian thing now?
A long time ago, Debian 8 or so it was a bug with Debian. Something about the command running without root despite the sudo command.
Yeah except it would be iptables-restore < old_fw_rules.bak
Fun fact: When you do iptables-save, you have to redirect the output if you want to save it to a file. But when you use iptables-restore, you don’t need to pipe it back in, you can just use the filename!
It wasn’t always that way. At one time you had to so I still do.
Totally! I still catch myself doing that sometimes. Old habits die hard
Lol.
Just tailscale it and this will never happen again.
(Set the whole interface of tailscale0 as a trusted network)
Nice drive to clear your head.
This is the NetAdmin’s problem. And he’s got 3 ways to get into the datacenter, so he goddamn well better have an answer that doesn’t involve airfare. Worst case, he’s gotta use remote hands, but that would be embarrassing, and I’d not let him forget it. Nobody forgives me when I screw up a server cluster, so he gets no latitude when he takes a datacenter offline.

What’s really fun is hearing “oh shit” from the UPS maintenance tech followed by darkness and silence.
