Well, I thought it worked great but it doesn't. I applied all these commands to the BBB in question and specifically to the root password entry but I am still unable to get into it. When I attempt to log in with root, and enter a null password, I still get "access denied". Same with all other usernames and passwords.
Could it be a file permissions problem? On Wed, Mar 31, 2021 at 9:10 AM Bob Hammond <[email protected]> wrote: > amf, > > THIS works great!
