This is an internal USB connection which provides RShim connectivity between the BMC and BlueField.

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).

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.
