My first thought (although I am very tired so it may be useless) is that
SSH is kicking the authentication attempt after 3 tries - admittedly
Medusa should have established another connection and carried on with
the brute force, but like I said, its just the first thought that
entered my tired brain.

Just had another thought - have you even enabled the ability for root to
login on your Ubuntu?!

Cheers
