How to open a terminal on my PC to the PinePhone?

[amosbatto]

When I connect my Librem 5 to a Linux PC via a USB cable, I can use the command picocom /dev/ttyACM0 on my PC to open a terminal inside the Librem 5. This is very convenient, since it allows me to use my PC's screen and keyboard and to easily cut and paste into the Librem 5 terminal.

However, I can't figure out how to get picocom to work with the PinePhone. How can I open a terminal in the PinePhone on my PC?
I'm currently running Mobian, but I would be interested in hearing solutions for other operating systems as well.

【On your phone】

Code:

sudo apt install ssh
sudo systemctl enable ssh

Then check your IP address (should be 192.168.x.x, 172.16.x.x, or 10.x.x.x, replace "x" with whatever shows up).

Code:

ip a

【On your PC】
ssh mobian@(IP address of your phone)

Then to skip the password (optional step, but very convenient if you frequently login):
【On your PC】

Code:

cat .ssh/id_rsa.pub

(Copy the output, if there is none or an error message, generate your SSH key.)

【On your phone】

Code:

mkdir .ssh # If not done already
nano .ssh/authorized_keys # or vi .ssh/authorized_keys, or vim .ssh/authorized_keys, or mcedit .ssh/authorized_keys etc.

(Paste the output you copied and save the file.)

If you really want a serial terminal rather than ssh you'll need to check how they configure the USB gadget mode. This is more of a pointer for research than a set of instructions as I don't know the details. There's an example in the Mobian wiki for changing between different networking gadgets at runtime using entries under /sys/kernel/config/usb_gadget/g1

There should be a similar way to add a serial gadget.
Once you have a serial interface you need to start getty or similar on the serial port, whether manually or using a service file like getty@ttyGS0.service
