Use unprivileged port numbers for your services.

Not sure I can expand on it a ton more in a way that will make sense if it already doesn’t sound familiar.

Basically, there are various methods to authenticate yourself to most services. Password is usually the weakest and most succeptible to brute-force and social engineering. There’s certificates, key pairs, RBAC…etc. You can even setup TOTP/MFA really easily for anything that supports it these days. Just don’t leave a service hanging out on the Internet to get brute-forced by password though.

If you’re unfamiliar with this, start with SSH and key pairs. It’s probably the simplest intro and you can be up and running to try it out in seconds.

You cant. You can only do your best to make it as secure as possible, but given enough time, someone can break it.

Basic tips:

• don’t run any services on their defaults ports
• don’t allow password auth for any exposed service. Ever.
• run intrusion detection (fail2ban for simple ssh / Crowdsec for something a little beefier)

For ssh specifically, lock down your sshd config, make sure only key-based auth is enabled, and maybe as an extra step, create a dedicated user, and jail it by only allowing it access for the commands you need to interact with.

Look into a Gl.Inet device. Ships with OpenWRT and can run whatever you want as an integration.

Well if you’re talking about isolated networks, that’s a different story, and not in your post. That’s a completely different scenario than what you posted about.

In that case, you could also use port forwarding and IPP via CUPS to achieve the same result without needing to build a web form. If you’re unfamiliar with CUPS, try enabling the WebUI and setting it up from there, but there is an option to allow printing from the internet, meaning it’s enabling IPP and accepting requests from outside the source network it’s hosted on (not the global internet, because surely you have a firewall on the edge router of your home network), effectively creating a bridge between your two networks for this specific purpose and only using that one port for printing.

Just going to say it again: IPP (Internet Printing Protocol) via CUPS solves for all of this, but you seem destined for a specific thing you want to do and don’t actually need help with your current issues, so not sure why you posted here.

🙄

“Pedantic Asshole tries the whole ‘You seem upset’ but on the Internet and proceeds to try and explain their way out of being embarrassed about being wrong, so throws some idiotic semantics into a further argument while wrong.”

Great headline.

Computers also don’t learn, or change state. Apparently you didn’t read the CS101 link after all.

Also, another newsflash is coming in here, one sec:

“Textbooks and course plans written by educators and professors in the fields they are experts in are not ‘peer reviewed’ and worded for your amusement, dipshit.”

Whoa, that was a big one.

I am saying that CUPS requires zero drivers or anything else from clients. It advertises the printer on the network, a device sees it, and submits a job. That’s it. Exactly what you are describing doing with a web form, except CUPS already does all of this.

Sounds like you’re not sure how it works.

CUPS already does this though, and that’s where I’m getting confused. This is the entire point of CUPS. If your issue is with drivers, then you need to configure it to just print from its own driver via a spooled queue like PostScript, or maybe IPP.

That’s not what he’s asking at all

Gotta say, this question and the process explained threw me for a loop.

You have a network print server where it’s advertising an available printer, but instead of the native printer system on a client device, you want to NOT use the CUPS server to print? That’s what it’s there for. I’m confused on why you have it then.

If your goal is just to have clients print as directly as possible to a printer…you already have that with CUPS running. I guess I’m not getting why submitting via web form is useful in this case.

LITERALLY from a “baby’s first 'puter” course: https://highered.mheducation.com/sites/007256380x/student_view0/part1/chapter2/reading_selection_quiz.html#:~:text=Although computers may appear to,humans who programmed the computers.&text=Humans are smarter than computers.&text=It is extremely time-consuming,that it makes correct decisions.

Or if you need something more ELI5: https://www.reddit.com/r/explainlikeimfive/comments/160lwe8/eli5_where_exactly_do_computers_make_decisions/

It’s Boolean. This isn’t an opinion, it’s a fact. Feel free to get informed though.

Everything you just described is instruction. Everything from an input path and desired result can be tracked and followed to a conclusory instruction. That is not decision making.

Again. Computers do not make decisions.

Using that as an example. Same premise.

Just use whatever works best for you. Just make sure there is a way you can easily export data from the tool in case you need to migrate to something else in the future.

The problem is that OP is asking for something to automatically make decisions for him. Computers don’t make decisions, they follow instructions.

If you have 10 similar images and want a script to delete 9 you don’t want, then how would it know what to delete and keep?

If it doesn’t matter, or if you’ve already chosen the one out of the set you want, just go delete the rest. Easy.

As far as identifying similar images, this is high school level programming at best with a CV model. You just run a pass through something with Yolo or whatever and have it output similarities in confidence of a set of images. The problem is you need a source image to compare it to. If you’re running through thousands of files comprising dozens or hundreds of sets of similar images, you need a source for comparison.

I think you’re doing this on hard mode. K8s and Longhorn gets you what you want.

You could try Ceph in your setup, but you’re going to run into issues if your environments aren’t all exactly the same.

Well how would you know which ones you’d be okay with a program deleting or not? You’re the one taking the pictures.

Deduplication checking is about files that have exactly the same data payload contents. Filesystems don’t have a concept of images versus other files. They just store data objects.
