I installed 2 VMs on VirtualBox.

1. VM 1:
   Windows XP with FreeSSHd and PuTTY installed.
   IP address: 10.0.0.2
2. VM 2:
   Ubuntu 12.04 LTS Server Edition with OpenSSH installed.
   IP address: 10.0.0.3

From VM 1, I run PuTTY with the IP address of VM 2 (10.0.0.3) and port number 22. I get prompted to input the username and password of VM 2 and everything works fine.

From VM 2, I run on the terminal (Ubuntu): ssh [email protected] , I get prompted to enter the password of VM 1. I do so, but it says my password is invalid (while it is the correct one). I even deactived the Firewall on VM 1, but still the problem is here: my password is not accepted from VM 2.

Is this due to some settings maybe I must do on VM 1 (Windows XP) so as I can access it with SSH ? Maybe it has something to do with the Firewall of Windows XP ?

Important information:
ping 10.0.0.2 from VM 1 and ping 10.0.0.3 from VM 2 are working successfully.
