title: tmux not re-attaching
body: <p>I recently switched from using screen to tmux (obtained through macports), as I like the feature set more. However, I can't seem to get tmux to reattach from an alternate location, like I can screen.</p>
  
  <p>At home on my mac, I will open up iTerm2, my default shell is zsh, and I will begin a tmux session with <code>tmux</code>. I get all my spits set up, ssh'd into the proper servers, etc., and work for a while. Time to go to work. <code>&lt;C-a&gt; d</code> - tmux detaches.</p>
  
  <p>I get to work, where I use a windows xp machine. I fire up putty, ssh into my mac back at home, attempt a <code>tmux attach</code>, and get an error message:</p>
  
  <p><strong><code>no sessions</code></strong></p>
  
  <p>I cannot seem to determine why this would happen. I am not afraid to dig into this, but don't even know where to start. Thoughts?</p>
  
  <p>P.S. I have already removed my .tmux.conf file, so it's using the default config.</p>
