title: Git (SSH) hangs during clone/push/pull
body: <p>Whenever I try and perform an operation using <code>git</code> (e.g. <code>clone</code>, <code>pull</code>, or <code>push</code>) over SSH the git client seems to hang and time out indefinitely (I've left it running for half an hour to no avail). I have my SSH keys loaded (using BitBucket). I am able to perform anything I need via HTTPS, and SSH is the only thing that appears to break. </p>
  
  <p>Here is some console output from an attempted pull</p>
  
  <pre><code>$ GIT_TRACE=1 git pull
  16:44:05.679911 git.c:344               trace: built-in: git 'pull'
  16:44:05.681453 run-command.c:334       trace: run_command: 'fetch' '--update-head-ok'
  16:44:05.686650 exec_cmd.c:120          trace: exec: 'git' 'fetch' '--update-head-ok'

  </code></pre>
  
  <p>Anyone have any idea what could be happening?</p>
