Is there anyway to create a sandboxed SFTP server to interact with an outdated document scanner?

I have a ADS-27000w and it only seems to work with rss keys to upload documents to an SFTP server.

I did update the firmware. I would prefer not to lessen the security on my server pc just for this scanner.

Is there a simple way to run an SFTP server so I can upload documents securely to it?

Thank you.

You could run a 2nd sshd service with systemd where you use namespacing, chroot & drop most capabilities. (Basically a container) You can also change the default logindir of sftp. Look at https://www.redhat.com/sysadmin/mastering-systemd and man sftp-server.

Linux Questions

@linuxquestions@kbin.social

A place to ask Linux-related questions, post advice and suggestions, etc.

Any questions pertaining to Linux from novice to greybeard level are welcome.

Asking Questions:

Please provide enough info to for people to actually help you. While there are some things that are generally the same, there is no one "Linux" - every distro has some things they do different and you'll get better answers if you provide some info.

And remember the people here are helping you purely out of their own good will - so be nice!

If you are encountering a problem, please include:

Which distro you are using
A brief summary of the problem
Any steps you have attempted
Relevant details such as hardware specs (see below), application versions, etc.

Capturing System Specs

In almost all cases, posting output from

inxi -Fmz

either as in a code block, as a linked file, or as a screenshot - will be appreciated. Some distros may pre-install inxi but on others (such as Fedora), you may need to install it yourself. But we understand that there will be times when you are unable to provide this info (such as with boot problems).

The output from inxi info should be safe (especially with the -z option)... But in general,YOU SHOULD ALWAYS REVIEW OUTPUT AND REMOVE ANY PRIVATE DATA BEFORE POSTING ONLINE (e.g. replace "Your Name" with <redacted> or something similar - this helps in preventing doxxing, identity theft, and similar issues).

Some common graphical screenshot apps:gnome-screenshot, ksnip, shutter, and flameshot . There are also terminal-based ones like maim and scrot.
There are plenty of free, text-pasting sites (e.g. pastebin.com) out there that are arguably better than pastebin itself. Any of these should work. We recommend any of the instances of the opensource PrivateBin. But you can find more options listed here.
To copy text from a terminal app, first open a terminal (Ctrl+Alt+T), then run the command, then to select text hold down the left-mouse and drag to select. Once selected, release left mouse and either press Ctrl+Shift+C or right-click on the selected text and choose "Copy" to copy text to clipboard.
You can also format the text as a codeblock. To do so, select the text in your post and clicking the icon that looks like a </> symbol. For larger outputs (more than 2-3 lines), it is recommended to add a blank line above and below the output to help with formatting.

Recommended Beginner Distros:

Please keep in mind that this is not to say other distros are necessarily "bad" for beginners. Linux is not Windows or Mac, so there will be things to adjust to. This list of the distros is what we think users trying Linux for the first time (and presumably having little or no experience with it) will have the easiest times adjust to. It is still recommended to try them and to watch videos on youtube etc.

Rules

Rules

Please try to be decent with each other.

This is not the place for debating which distro/app/text-editor/etc is superior, nor is it the right place for showing off memes/jokes/news/tweaked desktops/wearables/stickers or so on. If that's what you are looking for, see above for places where you can post those things.

Spamming sites and/or asking for payment are categorically not welcome here.

When asking for help:

Please remember there is no paid staff here - the people helping are everyday people just like you that are taking time out of their day to try and help. We all know that running into problems can be frustrating but do your best not to rant too much or take it out on others.
Try to provide enough info for people to help (see above) without going overboard and drowning in detail.
You are welcome to post your question elsewhere as well (in fact, it is encouraged).
Please remember to update your post as SOLVED whether you get help here or somewhere else - kbin, unlike reddit, allows you to edit your post titles.
If you find a solution to your problem that isn't mentioned here, please consider documenting the steps here as well - that might potentially help someone else facing the same issue!

When leaving responses:

Please avoid "RTFM" style comments. Yes, we know it was sort of an in-joke back in the days, but aside from not really being helpful, many newbies won't understand that it's often a joke. Likewise, simply leaving a link to a top-level document can be confusing. Especially if the documentation has many sections or the site later goes down. Instead, please consider an answer that address the immediate ask as best as you can, along with a link to the relevant section of the documentation (if possible) for more information.
We all have our own software/distro/etc preferences but please make every effort to avoid putting down what you may see as bad choices. If you don't like snaps or something else it's fine to say as much, just please no ranks or insulting the askers for using a given distro/app/whatever.

So with my homelab computer, I want to have it so that it stays on during the day, and then at night it will hibernate. Do any of the desktop environments allow you to set this up? Or is there a tool out there that will let me schedule power management in this way? #Linux #linuxquestions
