Shell access via SSH

You can use SSH to access a shell from your PC. This is useful for debugging or more advanced shell usage.

You need a SSH key-pair for this. Logging in via password is disabled by default.

Создайте публичный ключ

If not already created, create your public key. Default choices should be fine for LAN. You can leave empty password if you don’t want to deal with it each time:


Скопируйте публичный ключ на устройство

You need then to transfer your public key to your device. There are multiple ways to do this. These are a few options:

  • Connect the UBports device and the PC with a USB cable. Then copy the file using your file-manager.

  • Or, transfer the key via the Internet by e-mailing it to yourself, or uploading it to your own cloud storage, web-server, etc.

  • You can also connect via adb and use the following command to copy it (Some devices cant support ADB, check the devices page to learn more.):

    adb push ~/.ssh/ /home/phablet/

Настройте устройство

Now you have the public key on the UBports device. Let’s assume it’s stored as /home/phablet/ Use the terminal app or an ADB connection to perform the following steps on your device.

mkdir /home/phablet/.ssh
chmod 700 /home/phablet/.ssh
cat /home/phablet/ >> /home/phablet/.ssh/authorized_keys
chmod 600 /home/phablet/.ssh/authorized_keys
chown -R phablet:phablet /home/phablet/.ssh

Now start the SSH server. If you are using an Android-based device:

sudo android-gadget-service enable ssh

If you are using a Linux-based device (like the PinePhone):

sudo service ssh start


Теперь все настроено, и можно использовать ssh

ssh phablet@ubuntu-phablet

or, if that does not work

ssh phablet@<ip-address>

To identify the IP-address of your UBports device, open the Terminal app on your device and run the following command:

hostname -I

The output is a list of IP addresses separated by spaces. Use the IP address that matches your subnet. On your PC or laptop:

debian2:~/$ hostname -I 2001:982:89e9:1:bc6b:758:7ba2:c190

On the phone:

phablet@ubuntu-phablet:~$ hostname -I 2001:982:89e9:1:ef68:5f7c:3db4:c0d3

In this case you use the second IP address

Конечно, теперь также можно использовать для передачи файлов сервисы scp или sshfs.
