instant at the authoritative server, but anyone querying through a recursive resolver could still get the old status until the ttl expires. what ttl would you use for this?
I too am using Firefox on Linux. Are you by chance using a VPN hosted in AWS? I normally let VPS through but AWS has some special abusers that got my attention. I moved that out of the way for now. Thus far 2795 real people and 8888 bots. I have some room for improvement on false positives but we are getting there.
The real challenge is not finding another channel for transmitting personal information. It is finding something else for the FINGER protocol to do. (-:
Old versions of Safari could get that. I am being an opinionated ass and practicing hostile security paternalism because the safety and bot-filtering benefits outweigh the cost of supporting old clients. I do even stranger things.
If a site has a large set of TXT records, they can be used by clients that spoof packets to request large volumes of answers by DNS servers. This is called an amplification attack. Many tiny spoofed requests in, many large answers out.
Indeed. For what it's worth the spoofing aspect got better for a while then plateaued. [1] bcp84 / bcp38 adoption has pretty much stalled out. No idea what to do with the remaining ISP's.
What is this altchan.org place? Looks very new. Where's the reply button?
Its just a private fork of an open source anonymous image board. I had a static blog for it but I got bored and moved all my blog posts to the image board. Probably a rather unorthodox experiment. The reply button is at the bottom right. I might change that.
And why do we want finger to exist?
There were discussions in the past about the finger service and how hardly anyone runs it any more and even less likely to be found on the open internet. DNS seemed like a good replacement for it to me as more and more people have domains now and authoritative DNS servers are likely to be more secure and distributed I think. Maybe one day specific groups of people do something like this in place of sites like X. half kidding
Now instead of having a special purpose client, one need only query a DNS record. In this case I use "dig" as the example but there are other DNS tools people might prefer to use.
Just found out macOS has it too. Created a .plan file and used finger on my user name and it showed the plan. There's no fingerd or anything listening on the port though, but it worked locally. Neat.
It's just a shell function so in this case if one had a terminal app that has a shell one could add the function. No idea how feasible that is on a phone.

Fun. But a status needs to be updated semi-frequently and my dns service only offers api mgmt for bigger customers.
I guess I could delegate a zone to another provider who does.

That's a good idea. One could delegate to a stand alone instance for instant updates.

Something low like 60 to 90 seconds should be fine unless they are an influencer, then we could monitor their live stream.
Page does not seem to work with Firefox on Linux, or maybe its just down.

I don't need it.

Seems like I get served gibberish bytes in the response body when visiting this site! I promise I’m not a bot :(

> many large TXT records can be abused for DDoS purposes. dig -t txt ebay.com for a DDoS Example used today
What does this mean, I see a bunch in the lookup but I don't understand the ddos part
If a site has a large set of TXT records, they can be used by clients that spoof packets to request large volumes of answers by DNS servers. This is called an amplification attack. Many tiny spoofed requests in, many large answers out.
That's just the braindeqd design of DNS, responding to arbitrary UDP packets without authenticating the IP address of the sender.

Because it allows for an easy interface to see what someone else is up to without needing to load a JS-heavy page.
Assuming you have this finger app installed. My Android store does not seem to have one, for example.
Finger is a protocol. It's older than IP.
You can read about it in RFC 742.
Unix, Linux and BSD have finger built in.
Just found out macOS has it too. Created a .plan file and used finger on my user name and it showed the plan. There's no fingerd or anything listening on the port though, but it worked locally. Neat.

A terminal emulator is more heavy than a dedicated app is
I will leave writing an app to someone else. I've watched others go through all the challenges of getting into app stores and it's just not for me.
Fortunately some phones allow you to install apps, not just get them through the overpriced shit store.
If it has a shell and telnet/nc it has finger:
echo user | nc example.com 79
