1) Generate your keys on your local machine:
	- ssh-keygen -t rsa
2) When prompted for a password, do not enter one.  This will generate a
password-less key called id_rsa, and a public key id_rsa.pub
3) Copy the id_rsa.pub key over to the machine you want to ssh to.  NOTE:
change the filename first or you may overwrite your existing RSA key for
your remote host.  Like this:
	- local: cp id_rsa.pub local.key
	- scp local.key remote:
	- cat local.key >> .ssh/authorized_keys
