Another post, of the top of my head!
I seem to recall that when I first installed my MyBook, I could ssh login via terminal on my MackBook to the NAS. When logged in you could use su to perform root tasks like changing chmod codes and file ownership.
Now (one NAS firmware and several OS X updates later) I try to change into root (su) and the NAS respond that su is an unrecognized command. Neither su, sudo nor root works. There are files on the disk that I would like to change owner/permission status for. But I can’t chmod or chown because I don’t have sufficient permission. I cannot become superuser anymore, so I cannot do anything about it!
Anyone have any suggestions or ideas as to why su doesn’t work, and maby if it can be enabled again?
