I am not familiar with de-ice, however:
It is trivial to deny user access. Maybe as it is a test system that your user was easily found with a hydra scan but that user (adamsa) is denied ssh access!
Of course, the password might be wrong!
Of course, the port may no longer be open!
Incorrect choice of protocol (1 or 2) in your ssh client
Might I also suggest:
man ssh
man sshd
