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.
Create your public key¶
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:
Copy the public key to your device¶
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 filemanager.
Or transfer the key via the internet by mailing it to yourself, or uploading it to your own cloud storage, or webserver, etc.
You can also connect via adb and use the following command to copy it:
adb push ~/.ssh/id_rsa.pub /home/phablet/
Configure your device¶
Now you have the public key on the UBports device.
Let’s assume it’s stored as
/home/phablet/id_rsa.pub. Use the terminal app or and adb connection to perform the following steps on your phone.
mkdir /home/phablet/.ssh chmod 700 /home/phablet/.ssh cat /home/phablet/id_rsa.pub >> /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 phone:
sudo android-gadget-service enable ssh
If you are using a Linux-based phone (like the Pinephone):
sudo service ssh start
Now everything is set up and you can use
To identify the ip-address of your UT device , open Terminal application in your phone and run the following command:
The output is a list of IP addresses separated by spaces . Use the first IP address from the list.
Of course you can now also use
sshfs to transfer files.
