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.
Crea la tua chiave pubblica#
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:
ssh-keygen
Copia la chiave pubblica sul tuo dispositivo#
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/id_rsa.pub /home/phablet/
Configura il tuo dispositivo#
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 an ADB connection to perform the following steps on your device.
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:
sudo service ssh start
Connettere#
Ora tutto è pronto per usare `` 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
192.168.42.41 2001:982:89e9:1:bc6b:758:7ba2:c190
On the phone:
phablet@ubuntu-phablet:~$ hostname -I
10.55.74.177 192.168.42.52 2001:982:89e9:1:ef68:5f7c:3db4:c0d3
In this case you use the second IP address
Ovviamente ora puoi anche usare `` scp`` o `` sshfs`` per trasferire i file.
