Mr.Freeze

I have tried that and for some reason I couldn't connect and I guess all the attempts has locked me out. This is the error message I'm getting.

Just bought the pineapple nano to to start experimenting with since I plan to make networking security a career. I have a macbook pro and am trying to change the addresses on the pineapple to match my ICS, but the issue I am having is I don't know the ssh password. I have tried every password i could think of and have found in guides. Any help would be greatly appreciated thanks.
