In the lifetime of your printer, you'll likely have moments where you need to start over from scratch and re-flash your microSD with a new OctoPi.
I really wouldn't complicate matters by dropping the PiVPN on there as well. A Raspberry Pi Zero W is $5, you can get a 4GB microSD card for almost nothing these days, the power adapter is another $5 and a case for it is another $5 = $19 plus tax plus shipping. It's a small price to pay for the remote access you get in return.
And it's not just for your printer, you can remote into your desktop computers and servers, whatever.
Maybe it helps someone to make a first few steps into basic auth using the already installed haproxy on Octopi. I know this is not the most secure way, but I know 2 things: every installation out there that was at least secured a little bit is less risk, and most users won't use VPNs but cloud solutions instead, probably. Since clouds are insecure by design, I guess using the available haproxy and some basic user auth is a big step forward. Also, you can use every standard browser, there is no need for using any additional software or service. A small manual
You likely can, but... You know, depending on the firmware, your PI could have lots of load already, so I wouldn't recommend it. Get a Pi Zero W and a power supply, and print a case for it.
I'd say this is kinda overkill. You need to have your home computer running, being waste of energy and an additional potential risk (yes, every electrical device operating while you are not at home is a risk). Plus, I tried to operate a TV-controlled PC through my iPhone. Once. Will never do it again. Never ever.
if you just type octoprint in the search of shodan.io, you sadly get a bunch of secured but often unsecured octoprint istaces for anyone to mess around with!!
Sou should cange the title to a warning and make a pic like tis one as the webcam stream, to help em
Honestly, I think foosel's done a good-enough job of first telling them what not to do and then upping the stakes by including a warning on their interface. She's created at least one thread on the subject, talked about it in video blog posts and has spent a fair amount of time educating people.
And here within the forum we do everything we can to convince people how to correctly setup their printers for safety.
OctoPrint Anywhere - very limited doest not even let you send gcode to machine.
So I hooked up a old laptop and installed TeamViewer on it , Now I can access Original octoprint UI from anywhere.
Next I am planing to replace laptop with Android Phone to conserve energy .
"Whether you use a reverse proxy, or VPN to access OctoPrint; I recommend putting it on a separate physical box to the box connected to your printer. Running everything on a single server is just asking for trouble."
So I had a few questions here. I'm currently using a Raspberry Pi 2 running Octopi. I'm thinking about purchasing another Pi, just deciding which version I should choose. Are there any specific specifications I should be looking for when purchasing another Rpi to solely run as a VPN server? Will the Rpi Zero W perform the same or close to, as say, the new Rpi 4? Would the Gbit ethernet connection on the Rpi 4 attached to the router give me better performance vs Rpi Zero W's wireless & is it enough to justify the price difference?
Also, is a VPN connection to my octopi instance enough on it's own? Should I also use a reverse proxy in addition to the VPN or would that be redundant? How about running SSL?
I have a firewall between my cable modem and my local network. The firewall software includes OpenVPN so I can establish a secure tunnel between something connected to the outside internet and my local network. Many commercial routers have VPN capabilities as well so it depends on your configuration to determine if an extra RPi would be the best solution.
Note: my cable modem is actually a cable router but I've configured it in bridge mode so I can use my firewall instead. My firewall runs IPFire which is a Linux-based solution.
I believe the router my ISP provided has built in VPN settings. I may try going that route first.
Are there any latency issues with setting up a VPN? I'm assuming in general that there is some in normal web browsing. Not sure what, if any lag running an Octopi instance with multiple Webcam servers running.
Let me see if I understand correctly. So any latency has more to do with my home internets upload speed than the specs of my rpi? So would a wired ethernet connection help minimize any possible latency? Also, I mentioned the Rpi Zero W earlier. Would a Rpi 1 or even an old android phone work as a server?
Yes a wired connection would reduce latency but you have to have a really bad wifi to make much of a difference
I don't know which bandwidth a pi 1 or an old phone will be capable of - but yes - it would work
Yes but those things impact more on the bandwidth than on the latency in my experience.
But I never tested how much lag you get when you're using 100% of a bad connection.
I happen to have bad wifi atm. I'm not in charge of the internet here, but we're only getting 50Mbps. (very slow)..and there's interference issues on top of that. I ask about latency because I'd like to eventually have a few printer's up and running with 2 HD camera feeds on each machine . So with that in mind, I'm wondering if buying a used router running DD-WRT, set up in repeater mode and with a VPN server on it would get me farther than a Raspberry Pi.
