Enable SSH on Target Host

Refer: https://gist.github.com/slowkow/8798394

The hostname of your remote server.

host=myserver.com

Create this folder if it does not exist: ~/.ssh

mkdir ~/.ssh

Set the correct permissions (required)

chmod 700 ~/.ssh

Generate an RSA key pair for identification with the remote server

ssh-keygen -t rsa

Copy your public key to the remote server

cat ~/.ssh/id_rsa.pub | ssh $host 'cat >> ~/.ssh/authorized_keys'

ssh is very strict about correct permissions, let's not change home folder persmissions

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

At this point, you can connect to your server without typing a password:

ssh username@myserver.com
