We had a system at work that generated 4 character alphanumeric reference numbers. Originally to avoid this they just excluded vowels from the letters but eventually they grew enough they ran out of available reference numbers so they added the vowels back in and I had to built the blacklist to avoid stuff like this happening. I reckon I probably tripped every IT filter known to man in a week long period looking for swear words in a variety of languages 😂
The part where people share asterisks when they talk about their passwords? Just seems like good security honestly 😂 Glad Lemmy is keeping up with this pinnacle of security best practices.
What’s even wilder is if you look at the code of that package, all it does is include the is-odd package and then return !is-odd. And the is-odd package isn’t much better, it does some basic checks on the input and then returns n % 2 === 1.
I’d second afraid.org, have been using them for years and they’ve always been great. They also support dynamic DNS so if you’re on a dynamic IP address you can have the address be updated automatically when your IP address does.
More relevant to the question, I’m pretty sure you can create NS records for a subdomain as well. I was experimenting once a few years back with a DNS tunnel service and was able to get the DNS side of it configured. Never did get the service itself working but it was more of a curiosity at the time so didn’t spend a massive amount of time on it.
I use ocserv to provide a Cisco AnyConnect compatible VPN server. There’s an SSL proxy running on port 443 of my gateway so the VPN is only accessible using the right domain name, and the server is running in a Docker container.
Main reason I go for ocserv over OpenVPN or Wireguard is when I used to travel to China for work I found it was able to get past the Chinese firewalls. No idea if it still holds true but a few years ago it was fine.
I can only assume this was the registration form for that Mr Beast video where he had 100 people in a room with one person of each age from 1 to 100.
For most of my internal services that are sitting behind Traefik I use step-ca which basically gives you a Let’s Encrypt style certificate while working over the local network. The root CA has a long expiry (so might not be what you want if your goal Is a short lived root CA) but the actual certificates for each service are short lived (a touch over 24 hours from memory?)
