Autologin using bash script

1. Create a new ssh RSA keygen:

[root@linuxtutors# ~]# ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (//.ssh/id_rsa):

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in //.ssh/id_rsa.

Your public key has been saved in //.ssh/id_rsa.pub.

The key fingerprint is:
