I was trying to access an old mongodb server that I havnt used for weeks. But RoboMongo and 3TStudio were both rejected, so I logged on with putty and found this:

```
> show dbs;
WRITE_ME  0.000GB
admin     0.000GB
local     0.000GB
thaihome  0.000GB

```

This pretty much looks like we were hacked, which is really strange cause the mongodb password were very long and full of numbers/letters/characters etc.. So we have no idea how they got in.

I do have backups of everything, so no harm done (other than hurt pride hehe). 

Question: Right now there is nothing in admin, so how so I log on to the database from e.g. Robomongo or Studio3T? How can you create a user so you can login again?

Question2: Does debian/ubuntu have a undelete command or otherway to recover deleted data? (if not I will restore from backup but it will take time)
