title: How to log out of SSH session without closing tmux
body: <p>Is there a command I can use to log out of an SSH session where I have tmux running?
  Currently, if I want to leave tmux running, I either close the entire window of my ssh session without logging out, or I just let the SSH connection die after inactivity. </p>
  
  <p>But I want to use a command to log out without closing the entire window. If I just type <code>logout</code>, then it closes my tmux session and still keeps me logged in to SSH. I then have to type logout again to close the SSH session. But I just want to type one command that disconnects SSH without closing tmux.
  Is this possible?</p>
