By default all know the original log/pass of the Dreambox
root
dreambox
I use personal password to protect intruder via ftp or http.
My personal password was inserted long time ago and at this day i can't remember, today finally i found the solution.
Thx to add-on TUBOX COMMANDER (TuxCom)
Without access from any other place, that tool is great, it’s a full internal DM explorer and you can edit any files on your DM.
Navigate to var/etc and there is the password file
passwrd
I edit and change the first line with this
root:V26.Uf.kSvoYg:0:0::/:/bin/sh
That restores the root/dream box original password
