I dont think you need to restart the daemon, have the .pub key from the client to .ssh_authorized_keys on server and do a scp.

If you are performing SSH from oracle user on source to root user on destination.

1.Generate SSh keys from oracle user source machine.
2.Copy the contents of .pub key from the generated keys into the destination machine .ssh/authorized_keys file for the root user.

then you can perform a

sourcemachine#scp /tmp/test.txt
root@destinationmachine

Hi ,
I have followed step by step the method given but still prompt for a password ,

Hi,
Here is the steps to make auto ssh.

First login on Server-A as user "a" and generate a pair of authentication keys.

[a@A]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/a/.ssh/id_rsa):
Created directory '/home/a/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/a/.ssh/id_rsa.
Your public key has been saved in /home/a/.ssh/id_rsa.pub.
The key fingerprint is:
3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A

Then login on server-B as user "b" and generate a pair of authentication keys. Do not enter a passphrase:
[b@b]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/b/.ssh/id_rsa):
Created directory '/home/b/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/b/.ssh/id_rsa.
Your public key has been saved in /home/b/.ssh/id_rsa.pub.
The key fingerprint is:
3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 b@B

Finally append a@A's new public key to b@B:.ssh/authorized_keys and enter b's password one last time:

[a@A]# cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'

b@B's password:

From now we can login to server-B as b from server-A as a without password:
[a@A]# ssh b@B hostname
B

Hi Toni,

If still not working check the permission for authorized_keys. It should be 644.

Hi Toni,

Let me simplify the steps.

1. On source system login as orcale user and execute ssh-keygen -t dsa
Hit 3 times enter key.
2. Copy id_dsa.pub to the destination systems /tmp directory and update this key to the /.ssh/authorized_keys as root user.
eg:
/tmp/id_dsa.pub >> /.ssh/authorized_keys

Make sure that /.ssh/authorized_keys has 644 permission.

Now login as orcale user on the system where you gerenrated key.
Then do scp root@
