title: git clone hangs forever on github
body: <p>When I follow point 5 (Test everything out) in the github <a href="http://help.github.com/linux-set-up-git/" rel="noreferrer">guide</a>, the ssh command also hangs forever. According to the guide, I should be presented with a message that "Github does not provide shell access". Below is my output from ssh -vT git@github.com</p>
