Greetings friends.
I want to set up a simple ‘data drop’ where some sensors I have in the real world — I use for class usually — can live. Most of the sensors live on *nix compatible devices (RaspberryPi, some Arduino Yun), so I figured I’d use scp or sftp worst case to get things from the device to the data drop. Eventually, I suppose I’d like to use an HTTP POST sort of thing so it will work with the newer Arduino WiFi, but baby steps…
As I am an ancient being, I figured,
- create unprivileged user of some sort
- give them a sandbox to upload that can be accessed from the outside world via some SSH related thing
- copy keys for no login and all that
- profit$
So I created a ‘server’ pi.flipphillips.com where that stuff could live. Now to create a user.
I’ve noticed a few things - there are multiple ways to create FTP ‘users’ in cpanel. I can create a ‘user’ and give them FTP (really sftp I assume?) access… or I can create an ‘ftp user’ and do something with that. But… hmph…
Alas- nothing I did user-wise seems to even allow me to manually sftp in to my machine (thanks for the new Ninja Captcha thing so I don’t have to keep sending help-desk tickets from trying 100x different ways of logging in) let alone ssh or other things using these newly created users. I can ssh in as ‘me’ but was thinking I’d rather not have my account-wide ssh keys out in a Pi that is buried underground in the woods measuring ground temperature.
Is there a ‘best practices’ for this sort of thing? I’ve searched the tutorials and documentation without much success… I’d file a help ticket but I’m on my way to a pleasant vacation, and there’s no hurry on this…
