SSH is a protocol allowing a user to access the command shell of a device. This is often used for debugging purposes, as it allows engineers to connect to a device remotely.
You can easily enable SSH access on the Plasma Cloud console:
- Log into the Plasma Cloud console;
- Select the organisation and network containing the device you want to grant SSH access to from the top right menus;
- Navigate to Settings > Network in the main menu on the left; and
- Enable the SSH toggle in the System section.
At this point, you need to configure the access method you want to use. You can use one or both of the following by filling in the related sections that appear after enabling SSH in the console:
- Public key authentication: Every user can create its own SSH key. This key-based authentication method allows you to log into a remote device without a password and is more secure than a password-based authentication. You can add as many public keys as you want to permit access to multiple users.
- Password authentication: You can set up a password to log into a remote device via SSH. Everyone can then use the configured password and the default username "root" to access the device.
If no public key or password is provided, SSH access will be disabled by default.
