I followed these instruction and everything worked as advertised until I tried to login to the linux machine from putty. When I put in my machine local ip address (192.168.x.y) the putty screen remains blank then times out. On the other hand, if I put in the hostname of my linux machine (John-HP-laptopname) the SSH server connects and prompts "login as:"
I then enter the only user name I have for linux and it then prompts "username's password:" to which I enter the password for that username. The system then promps, "Access denied followed by the same prompt "username's password:"

I have tried entering anonymous and that does not help. I have not idea what password it is asking for.
