Huh. The Remarkable2 tablet has a USB port for charging, but if you plug it into a PC it shows up as an ethernet adapter. So then you can SSH into it.

@foone Is it still like the rM1 where the root password is shown somewhere in the on-device help/manual/licenses?

that's an interesting approach to PC connectivity. Why be a serial port or a mass storage device when you can just be ETHERNET, with a virtual network to the tablet.

the SSH is also weird: It's not a fixed password. It apparently generates a random password, and if you go into the menus (Menu->Settings->Help->Copyright and licences) it'll tell you the SSH password it generated

I guess that's a good (or at least not terrible?) way to do it. It's slightly more secure, you're not going to get hacked by someone SSHing into your tablet because you're on their wifi, but anyone with physical access can SSH in if they need to

still you could have skipped all of this and just made it a serial port. you don't need authentication if it's a serial port.

I guess doing it this way makes it possible to reuse the same functionality to connect to the device from both wifi and USB? Since it's just some kind of linux machine.

@foone that's the way the OpenWRT One routers work: plug USB-C cable in from laptop and open up screen /dev/ttyX 115200I'd done something similar with physical wires/UART on an esp8266; but the singular USB cable, direct from laptop to machine port, was a much nicer experience 😜

@foone if you have physical access, how long does it take to bypass the screen lock?. That might be the answer.

@foone The GP2040-CE is an open USB gamepad input encoder design. It's got a button on the PCB which turns it into a USB flash drive (because it's based on the RP2040, so that's not new). It's got another button which turns it into a USB ethernet adapter to give you access to a configuration web site.

@foone See how many USB classes you can emulate in one device. Hold down another button and your keyboard turns into an HID mouse which is controlled Asteroids style by the keyboard. Hold yet another button and it becomes a webcam which displays abstract animations depending on the keyboard inputs. Etc, etc.

@foone This is how BB10 devices worked, too. Shows up as an Ethernet device. All the management utilities work over the network (which means some of them can also trivially work over wifi).

@foone oh, this is the default for a bunch of devices (all the Raspberry Pi ones for example) in the Nerves IoT framework. For development.USB Gadget networking over USB for both power and networking is really convenient.Though we typically shove an SSH key on there instead of password.How are you liking the Remarkable2?

@foone the authentication is a feature! otherwise anyone could snoop out all your notes if you leave your tablet unattended for a minute. RM has optional screen lock. so the physical port should be at least equally well protected

@foone I used to use the web interface using wifi all the time. Occasionally I would ssh into it too. But at some point someone had the bright idea to disable this interface at every reboot and the setting to enable it shows up only after plugging the remarkable using a usb.

@foone you can also enable ssh over wifi on the reMarkable, which is how my cronjob scp's updates to my page-a-day calendar with events from nextcloud and gcal. https://github.com/osresearch/pdfcal

@foone I’m still confused about why they called it remarkable 2. There’s been tons of other tablets before it that were able to be marked over and over again, this isn’t new.

@foone There are a bunch of advantages to the way that they've done it:After initial setup, you can use an SSH key and disable the password.Someone with physical access must crack the PIN (rate limited) or SSH to connect to the device.You can use scp / rsync to copy files, without needing to run kermit or something (who even has a kermit client installed these days).You can create a simple port-forwarding rule to expose it to your network.They also allow SSH over the WiFi if you enable it, now your device interactions are the same via WiFi and wired.Their sync software can work wired or wireless with the same TCP/IP code.TCP error correction comes for free, they don't need to do anything custom.
