Hi mansour77@yahoo.com,

Why do you create both RSA and DSA keys?

I would suggest trying the same steps with _only_ one type, say
"ssh-keygen -t dsa" on both servers, and cat over into authorized_keys.

Basically, my understanding of your log is:

1. Client is trying to authenticate with rsa key, but somehow it's not
there (on local box).

2. Client send dsa key, but remote box cannot recognize/ understand (it
expects rsa according to entry in it's authorized_keys) so the
last option is used as to prompt for a password.


I might be wrong, please correct me.
