check the permissions on the /home and /home/.ssh folders of both machines. you can also use the -v option with ssh to output all debugging to stdout.

ssh -v -l user machine

so you moved the id_rsa.pub or id_dsa.pub file to the remote server and added the contents to the .ssh/authorized_keys file? It might be authorized_keys2 depending on the config file. it kinda sounds like you either moved the wrong file, IE your private key or you need to tweak teh config file.

Hi,
Thanks for response, i copied 1d_rsa.pub key to remote server and append to authorized_keys2. In the config like this authorized_keys2.

What i am done is correct?

check the permissions on the authorized_keys2 file and you home directory, maybe run the ssh -v again.

Permission i given 600 to remote user /home/user/.ssh

how about on the local machine, ssh will not accept a key from a dir with loose permissions.
