The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa 2048 1b:12:d7:f0:4b:d2:3e:36:f8:48:2e:fc:98:6f:ae:60
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.

• Store key in cache? (y/n) y

Using username "root".

• root@noezel.tuxmen.de's password:xxxxxx
