These details don't matter but I am on a Ubuntu 12.04 machine and I want to ssh into my RaspberryPi without a password. I followed the standard procedure for setting up ssh without a password:

local $  ssh-keygen -t rsa

(hit enter for defaults to the questions)

local $  scp ~/.ssh/id_rsa.pub matt@raspihost:~/.ssh/authorized_keys

I logged onto the raspihost and checked all my permissions on ~/.ssh/ and on the authorized_keys file itself. It was still not working!
