Precedence: list

I have followed exactly the instruction but still with the same problem.

135 ssh-keygen -t dsa
137 cd .ssh/
139 cat id_dsa.pub >> authorized_keys2
141 chmod 644 authorized_keys2

when I do ssh localhost , i get still this

oar@lion:~$ ssh localhost
*Enter passphrase for key '/home/oar/.ssh/id_dsa':*
Linux lion 2.6.24-19-generic #1 SMP Wed Aug 20 22:56:21 UTC 2008 i686

What are other reasons that can causes that!

Wait a minute, rom the command listing in your original post it seems
that you might have generated and added the public key on the same
machine, is that correct?

You need to generate id_dsa.pub on the local machine, then copy it to
the remote host and add it _there_ to ~/.ssh/authorized_keys2

If you follow the instructions on
https://help.ubuntu.com/8.04/serverguide/C/openssh-server.html to the
letter, it should be fine.

Perhaps the issue is with the steps you took to generate the key. The
message you show above does not show that ssh is prompting you for
your login password, it shows that it's prompting you for your key
password.

Note that you can generate your dsa keys either with or without a
password. I always generate mine without a password, so I don't know
what I would see with the password. But I do know that when I don't
have a key set up at all, I get a different password prompt than the
one you show.

Here's from the ssh-keygen man page:

Normally this program generates the key and asks for a file in which
to store the private key. The public key is stored in a file with the
same name but ``.pub'' appended. The program also asks for a
passphrase. The passphrase may be empty to indicate no passphrase
(host keys must have an empty passphrase), or it may be a string of
arbitrary length. A passphrase is similar to a password, except it
can be a phrase

I hope this helps.
