As a new sage user, I recently compiled Sage-4.7 from source and it runs smoothly in the command line. However, when I set up the sage notebook, the expression returns no result in browser For instance, if you enter 1+1, then click "Evaluate", the cell turns green but then it keeps running and never returns anything. The terminal displays the following:

sage: notebook(interface='', server_pool=['sage1@localhost'],                 
....: ulimit='-v 500000', secure=True, directory="/tmp/work", accounts=True)  
The notebook files are stored in: work.sagenb                                 
*                                                  *                          
* Open your web browser to https://localhost:8000  *                          
*                                                  *                          
There is an admin account.  If you do not remember the password,              
quit the notebook and type notebook(reset=True).

I tried checking the installation using make check and it is fine. Can someone give me some ideas on how to proceed?

Thanks so much!

From the sound of things, it seems like the problem is coming from the server_pool=['sage1@localhost'] option you're passing to notebook. For that to work, you need to have a sage1 user created on localhost as well as making it so that the user that runs the notebook can SSH into the sage1 account without a password.

You should try to see if the notebook works correctly for you without the server_pool option and then check to see that those two conditions I mentioned above are satisfied.

Yes, that works for me. Thank you for the pointer!! Interestingly, there is actually an account called sage1 which I never created on the server.
