Passwordless sftp issue
Hello Experts,

I am trying to setup passwordless sftp from one of linux box to solaris box.

I have generated key-pair and below is the permissions of the respective files.

Code:
drwx------. 2 sftpuser sftpuser 4096 Dec 17 23:57 .ssh

drwx------. 2 sftpuser sftpuser 4096 Dec 17 23:57 .
-rw-r--r--. 1 sftpuser sftpuser  609 Dec 17 23:57 id_dsa.pub
-rw-------. 1 sftpuser sftpuser  668 Dec 17 23:57 id_dsa
-rw-r--r--. 1 sftpuser sftpuser  220 Dec 17 23:45 known_hosts
-rw-------. 1 sftpuser sftpuser 1675 Dec 17 23:44 id_rsa
-rw-r--r--. 1 sftpuser sftpuser  401 Dec 17 23:44 id_rsa.pub
drwx------. 5 sftpuser sftpuser 4096 Dec 17 23:40 ..

I copied id_rsa.pub using sftp to my solaris box and while trying to connect using public key it is still asking for password as shown in below snapshot.

Code:
bash-3.00$ sftp -o IdentityFile=id_rsa.pub sftpuser@IP
Connecting to IP...
sftpuser@IP's password:

Am I missing something here? Are there any configs that needs to be made for password less ssh to work..

Thanks in Advance for your kind help..

You don't copy the public key to the remote side, you append it to authorized_keys.

If still problem exists, run
Code:
ssh -vv user@IP

and post the output here.

Code:
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAtvWvGQMIpwuUxaMEShLkxw1BiAo9MHlrMI6rfjM8C+bfhzMxk7wXvtX/6M5Q3qLRxtb8YRgow9p81IJ7geDqbf3tETPh5G8NF6h8OkdfSssUC5phEic8D7tXXN+UM+jBj8aN
