  3. Deactivate the login with user name and password.

    NOTE

    Ensure login

    Perform this step only when you are sure that you can login with the created private key! Otherwise, you can no longer login to the IoT2040 and must reinstall the firmware.

    • Create a backup before you perform the next steps.

    • Open the file "/etc/ssh/sshd_config".

    • Change the parameter: PermitRootLogin without-password.

    • Change the parameter: PermitEmptyPasswords no.

    • Remove any superfluous packages from the Yokto image (optional).
      For security reasons, we recommend that the superfluous packages and binaries made available in the default image of the IoT2040 are deleted.

    • opkg remove gdbserver --force-removal-of-dependent-packages

    • opkg remove gdb-dev

    • opkg remove gdb
