I ssh’d into my printer and got a notification of updates available. Is updating recommended or asking for trouble?

Definitely do not update the Linux operating system on a 3D printer. The entire system needs to work together. The 3D printer bits were written to work with a specific release of Linux, which is an entire system with the kernel and a lot of other software layered on top of that. It’s a good idea …

[image] Liberty4Ever: keep your 3D printers off the internet NOTE: If you don’t install any remote access extensions on your klipper host your router firewall SHOULD effectively isolate your printer from the internet while still allowing you to use the “local network” to interact with your pr…

[image] Liberty4Ever: Updating Linux will almost certainly break a 3D printer because the 3D printer specific code is written to work on that specific “frozen in time” Linux system. It’s very unusual for Linux based appliances to have routine OS updates in the manner of desktop and server Lixux …

But they have to get past the firewall first. Assuming, of course, your Printer OS is free of intentional backdoors. You may not recall but a while back there was an issue with low cost cameras SHIPPING with back door code in their firmware what punched OUT through your firewall.

[image] Vergo: Because it’s far easier for the bad actor to integrate the printer to be part of a bot network thanks to a fully writable root filesystem than it is to do the same for a nanny cam. So THAT’S why msheldon’s Zero is working overtime and running hot when it’s idle. :smiley: …

[image] cardoc: Assuming, of course, your Printer OS is free of intentional backdoors. Obico Cloud is pre-installed, running and enabled by default. It’s up to you if that counts or not. I’ve stopped and disabled it in my printer at least since I have no use for it.

[image] Vergo: Obico Cloud is pre-installed, running and enabled by default. Yes that is a back door… or a feature waiting to be hacked. @sovol3d you really should ASK before enabling internet vulnerabilities.

I thought I disabled Obico on my Zero, but it’s running. I must have been thinking of my SV08, where I commented out all references to Obico in the configuration files and that eliminated it. That trick didn’t work on the Zero. I can turn off Obico in Mainsail’s pull down power menu but it turns …

Sovol & Obico have some kind of deal with the SV06 ACE & up…it is baked in so users can easily turn it on if they subscribe. I had to update Janus, but otherwise it worked fine.

Debian updates?
