Rooted, what a great box. Leant loads on this one so a massive thanks to the creator,
User hint : enumerate the obvious services and you will find some creds to use.
Root hint : This took me ages but look at the key service running on the box (the box name helps here) and the group membership of the user. Then google the service and how it can be configured from the command prompt. Dont give up on first attempt.
Enjoy.
Nugget!
