Hmmm, I have something along the same lines....
Here's a scenerio:
DB Name: yoda1_vb3
DB User: yoda1_user1
DB User Password: 12345
So, I have a dump I want to populate the DB with. The common command would be:
mysql -uyoda1_user1 -p12345 yoda1_vb3 <yoda1_file.sql.2
That should upload the file yoda1_file.sql.2 to the yoda1_vb3 DB.
It won't, access denied.
I can't use user=da_admin and passwd, that is not a valid user to the DB.
How do you upload a dump to a DB via ssh??
