Create connection to host without password need

Well, the first step is to create a RSA key. This can be done by executing:

ssh-keygen -t rsa

The second step is to tranfer this key to host so it can authenticate out connection. You shall transfer only the .pub file into ~/.ssh/authorizedkeys folder by executing:

scp ~/.ssh/myrsakey.pub <username>@<hostname>:~/.ssh/authorized_keys

Now, you must be able to ssh the host without using your password:

ssh <user>@<hostname>
