PubkeyAuthentication yes but it doesn't connect using the key file and asks for password

Hi

I try to use rsync by connecting from server 2 (backup) to server 1 (main) and get the backup files and i create the correct key and add it on the second server and i close the firewall on both and then i try to run my script.sh that is using a key file that i was create and is asking for a password and is not using the key file

---

I enable the:

Code:

PubkeyAuthentication yes

on server two in sshd config file and restart sshd but nothing

I was try also to disable the:

Code:

PermitRootLogin yes

so i can force it to use the key but nothing

Any ideas?

Maybe is related to an authentication method that the old Centminmod server is using?

Maybe old server is using RSA and new DSA?

How can i check it?

Do we use something newer now as the server 1 is a new Centminmod one?

Thanks

 

Main server has:

Code:

[root@server .ssh]# ls -l *
-rw-r--r--. 1 root root 398 Mar  3 22:26 authorized_keys2
-rw-r--r--  1 root root 395 Mar  3 21:41 known_hosts

Backup server has:

Code:

[root@ns363621 .ssh]# ls -l *
-rw-r--r--. 1 root root   0 Mar  3 13:28 authorized_keys2
-rw-r--r--  1 root root 403 Mar  3 16:43 known_hosts
