Changing Default Credentials Using bf.cfg

Ubuntu users are prompted to change the default password (ubuntu) for the default user (ubuntu) upon first login. Logging in will not be possible even if the login prompt appears until all services are up ("DPU is ready" message appears in /dev/rshim0/misc).

Warning

Attempting to log in before all services are up prints the following message: "Permission denied, please try again."

Alternatively, Ubuntu users can provide a unique password that will be applied at the end of the BFB installation. This password would need to be defined in a bf.cfg configuration file. To set the password for the ubuntu user:

  1. Create password hash. Run:

    Copy
    Copied!
                

    # openssl passwd -1 Password: Verifying - Password: $1$3B0RIrfX$TlHry93NFUJzg3Nya00rE1

  2. Add the password hash in quotes to the bf.cfg file:

    Copy
    Copied!
                

    # vim bf.cfg ubuntu_PASSWORD='$1$3B0RIrfX$TlHry93NFUJzg3Nya00rE1'

    The bf.cfg file is used with the bfb-install script in the steps that follow.

    Warning

    Password policy:

    • Minimum password length – 8

    • At least one upper-case letter

    • At least one lower-case letter

    • At least one numerical character
