Problem with ssh using RSA authentication on Windows 7

I am working on a 64-bit windows 7 machine.

I have installed ssh on my machine through cygwin.

I am trying to connect an XP machine to this windows7 machine through SSH using RSA authentiation..I am proceeding as follows:

1. On the XP machine, I create an RSA public/private key pair using the command

ssh-keygn -t rsa

following 2 files get created at ~/.ssh/ location :

id_rsa and id_rsa.pub

2. Next I copy the id_rsa.pub file on my windows7 machine.

3. Then I append the contents of id_rsa.pub to the file ~/.ssh/authorized_keys on the windows7 machine.

cd ~/.ssh

cat id_rsa.pub >> authorized_keys

chmod 600 authorized_keys

chmod 755 ~/.ssh

4. I restart the sshd service on this machine

5. I try to ssh from the XP machine to the win7 machine.



I am observing the following output:

...

..

debug1: Offering public key: /home/Administrator/.ssh/id_rsa

debug2: We sent a public key packet, wait for reply

connection closed by xx.xx.xx.xx
