Install SSH Keys on Yocto Project* Target

Two tools – data streams optimizer and cache configurator – need to be able to automatically connect the host system to the target system via SSH. If you would like your target system to be password-protected, Intel recommends creating a public SSH key and installing it on the target system. Otherwise, you will need to enter the password into a plaintext file when using these tools.
To create a public SSH key and install it on the target system:
  1. On the host system
    , generate an SSH key:
    ssh-keygen -t rsa -b 3072
  2. Copy the SSH key to the target system. Replace
    with the IP address or hostname of the target system.
    ssh-copy-id root@<target>
    cat .ssh/ | ssh <user>@<target> 'cat >> .ssh/authorized_keys'
  3. Test the installed key:
    ssh root@<target> ls
  4. Confirm that the connection is established without additional prompts.
