Tom’s Hardware: Mad lad stores and loads Doom from within DNS — TXT record type abused to store game data. “Network administrators in the audience are advised to grab their unsee juice from the shelf, as today’s home project is quite the double-whammy. First, it involves everyone’s favorite problem child, DNS. Second, a madlad named Adam Rice has managed to put Doom in it. That’s a paragraph […]

@bart heard me say when I moved my server that I didn’t really understand all of the DNS record stuff @tage told me to do. In this nerdier-than-usual Chit Chat Across the Pond, Bart explains all of it and teaches us about email sender validation. His explanation will help you to be able to send mail from your server that actually arrives at the intended inboxes.

#SelfHosting community, how do you get notifications about your projects?

I'm setting up a couple of #BASH #Scripts to back things up and notify me about events on my #RaspberryPi, but I've hit some roadblocks. Here's my situation:

- I know #email is one option, but I'm not set up for it yet. My domain is on porkbun.com, but its nameservers point to vultr.com, where my #WordPress site is hosted. The Vultr server is managed by a friend, so I don't have access to add #DNSRecords for platforms like #Brevo. I've asked him to add the records but am waiting on that.

- I've been using a #Discord webhook, but I've run into issues with rate limiting when scripts send too many messages. Long messages also cause errors.

Now, I'm exploring other ways to send notifications. Does anyone have suggestions for reliable methods or tools that work well in self-hosted setups?

I’ve got a #DNSRecords question, in case someone can help me solve it 🙂

I bought a .org domain with #Cloudflare Registrar and I need to set up its DNS records via the Cloudflare dashboard.

I’ve already added a CNAME record so that “www” resolves to ***.org; how do I set up an A, AAAA, or CNAME record for the root domain so that ***.org resolves even without the “www” at the beginning?
