Password-less SSH Login
Here is the procedure to establish trust relationships between Unix boxes for a particular user using SSH. it can be helpful in script file transfers and other admin activities.
Here i am using the source server as server1 and destination server as server2 as example.
1.Login as user whom you want to login without password on server1
2.Type: ssh-keygen -t rsa
Note: If you do not want to be prompted, leave passphrase blank
The default directory for SSH keyfiles is /.ssh/
4.copy the contents of /.ssh/id_rsa.pub (there should only be one line)
5.Place this line on server2,in /.ssh/authorized_keys
that's it, you should now be able to ssh/sftp/scp from server1 to server2 without being prompted for a password!
Note: Make sure, "RSAAuthentication yes" in your /etc/ssh/sshd_config file. On many Linux installations this setting is commented out in a default install
