Come with all the stuff you normally spend another $800 making a $150 printer work a little better, so its not that bad a deal when you tally up all the stuff a $150 printer is missing. Plus its 3 or 4 times faster than the $150 printer. The X-MAX 3 is the top of their line of printers. > There are so many things in this paragraph that I don't understand. > What is "QIDI"? Why would enabling full net access "overwrite stuff"? > What "stuff"? What is "kiauh.sh" and how is it relevant to this > question? They claim they custmized it to drive their printer better, but I'll reserve judgement on that. kiauh.sh (Klipper Installer And Update Helper) is a shell script that keeps a klipper and friends install up to date AND also keeps the OS up to date too, run it 2 or 3 times a week, and you always got the latest stuff as klipper, somewhat like marlin but faster is under fairly rapid development. And its doing things months ahead of marlin. > Either configure a static IP address for this host Which is what I want to do but I've been told that /etc/network/interfaces is not the "today way" to do it. OTOH its buster and I think that works in buster. However, my only access to work on this is ssh -X root@address, so I have to be sure I don't brick it. or set up a DHCP > server which will assign it the desired IP address.

I had set a 30 character passwd from a random generator based on the number of centuries it would take a hacker to get thru it.

Every other machine on my local net has a desktop and a browser, fully capable of downloading the newest yak milk recipe from a satellite fed, solar powered yurt 35 klicks north of Ulan Bator. Firefox is an IRQ pig, playing hell with the machines latency, so I don't cut steel and run firefox a the same time. > It sounds like you don't want a *physically* isolated network, but rather, > some kind of numeric subnet whose packets won't be routed to the public > Internet.

Sounds like something I could do with a bananapi-m5, And it would reduce my footprint at debians time servers by aabout 8 machines banging on them now. But that project is 4 or 5 lines from the top of the list. At present I'd like to blow away the systemd and install chrony, configuring that to take over one machine at a time. Can someone lead me to do that? The original protocol could push at intervals and ISTR I had it working on my amiga 2000 and on my color computer 3 running nitros9, circa 1999-2001.
