ssh authentication with key based access

[ankush grover]

Hey friends,

 I have configured cvs server on Fedora Core 3 .There are 2
repositories on the server.I am using SSH protocol for authencation
but the problem is that I am not able to do key based
authentication.Everytime I do import module or checkout module i get
the prompt for password whereas it should prompt for passphrase.

Let I am explaining what I have done.

I downloaded Cygwin and OpenSSH for windows.

create a home directory under c:\cygwin  for ex c:\cygwin\ankush.

Under c:\cygwin\ankush i created a directory .ssh .Then I generated
the key pair  with

ssh-keygen -t dsa.

I imported the id_dsa.pub to the cvs server .On the Cvs server for the
user ankush I did this

cat id_dsa.pub >> .ssh/authorized_keys.

I have checked the permission for .ssh it is 700 and for
authorized_keys it is 600.

Under /etc/ssh/sshd_config it is can seen that the Authorizedfiles is
authorized_keys.

I checked the log /var/log/secure but it seems there is no error in logs.

Can anybody guide me what wrong steps I am doing and what steps to
take to make it happen.

Thanks & Regards

Ankush Grover
