title: Can I reopen a jupyter notebook running on my server?
body: <p>I need to run some code that takes a lot of time, so I did the following:</p>
  
  <ol>
  <li>use ssh to connect to my server, use screen to start jupypter notebook server without web browser.</li>
  <li><p>use the following to redirect localhost:portOnMyMachine to port 8888 on my server:</p>
  
  <p>myName@serverAddress -NL portOnMyMachine:localhost:8888 ubuntu@DNSofMyServer</p></li>
  <li><p>Open my browser with localhost:portOnMyMachine</p></li>
  </ol>
  
  <p>And I could edit notebooks on my browser. Every time I need to edit my notebook, I just need to repeat 2 and 3. </p>
  
  <p>However, if I run some large program, I cannot see which line the kernel is working on when I log in again. There is no "<em>" symbol after the line number anymore. I guess it is still running something, because it will put a '</em>' after any new line I want to execute. </p>
  
  <p>So I was wondering if anybody could tell me how to re-open a running notebook and have it in the status before I close it?</p>
