Re: [sage-devel] Re: Notebook stuck on "N?" with a worksheet
Here's a quite popular service to share Jupyter notebooks together with a preset environment (e.g., a SageMath kernel) : http://mybinder.org/ Quite a different workflow compared to sharing a notebook on a SageNB server, though.

Running ./sage --notebook=jupyter will run the Jupyter server, NOT JupyterHub. This is a single-user setting: the Jupyter server runs as your user, and can acces any file your user can access (the file explorer is rooted in your working dir, but you can go anywhere in the file system using Python). JupyterHub is a different beast: it is a server that waits for connections and spawns Jupyter servers under different userids. So this is similar to running ./sage --notebook=jupyter as two different users in their respective homedirs. If you want to try out JupyterHub, you will have to install it separately, and link the Sage kernel to it. I find the JupyterHub docs pretty well written and easy to follow for a Hello world test https://jupyterhub.readthedocs.io/en/latest/getting-started.html You can test them in a virtualenv for an easy throwaway setup. Volker's scripts may be another good starting point, although I haven't tested them. Alternatively, there is a docker container here : https://hub.docker.com/r/jupyterhub/jupyterhub/ which is also good for testing. I agree with Dima that a tutorial for setting up JupyterHub in a SageNB-like way would be much welcome. I have the feeling that the Jupyter/JupyterHub/SageMath integration is still a bit of a moving target ATM, but we should try to write this sooner than later.

Re: [sage-devel] Re: Notebook stuck on "N?" with a worksheet
> As far as I know, Jupyter(hub) does not have such a feature since it > completely relies on the OS for access checks. That's not correct. JupyterHub supports arbitrary authenticators: https://jupyterhub.readthedocs.io/en/latest/authenticators.html In particular, there is an LDAP authenticator: https://github.com/jupyterhub/ldapauthenticator If I understands Jori's loud thoughts, he wants to mix an LDAP authenticator with the default PAM authenticator. It shouldn't be too hard to write a class that tries them in some order, although I'm not sure that's the best solution. > A notebook is just an ordinary file owned by some Unix user. That is pretty much configurable too : https://jupyterhub.readthedocs.io/en/latest/spawners.html I think the hardest thing to achieve with jupyterhub is notebook sharing, at least in a fashion similar to the classic notebook. There is a concept of *admin account* in JupyterHub (disjoint from Unix admins). Admins can run the Jupyter notebook as any other user, so they can see and run all the students' notebooks. > How others teach Sage? Here I make a Sage account of the form > "Coursecode-Year", and the teacher asks students to share worksheet > with that account. For the first year this time, I set up a jupyterhub with a PAM authenticator. I create a unix user account for each student (and teacher). This is fine with us, because we want them to also have ssh access (and it's only ~10 students). They can use Python, Sage, and Julia via the Jupyter notebook, and can also run any of those and much more from a shell. Added bonuses: - There is an in-browser shell in JupyterHub. Very practical for those students who don't know how to run ssh on their home computers. - JupyterHub file view lets the students upload and download any kind of file from the server, not only noteboks. So this makes a very simple "cloud host" for them to have all their work available from anywhere (e.g., the C files they write in the system programming class). When I want to share a notebook with the students, I share a static .ipynb file via gist, and visualize it via nbviewer. e.g.: http://nbviewer.jupyter.org/gist/defeo/4adb727f7608dfd2c75eb7699d670fb7 When I want to see the student's work, I ask them to send me the .ipynb by mail, or directly access their notebooks using my admin account. Works like a charm. I'll be looking at custom authentication soon. Luca -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

Hmm... OK. Thinking aloud: As Sage may eat much CPU and/or memory, I want it to be on it's own server. That server should connect to our LDAP, and have normal Unix accounts. Also we need some local accounts for courses. Managing users is then not possible from Sage UI, but with normal Linux commands. But that's not a problem for us. Normal shell logins should be disabled for almost all users, but some researcher might use Sage from command line too. I must check if sharing worksheets works, see if I can run plain Python2, R and Octave too from UI. What else? Check how much memory every worksheet eats (no, we don't have memory ballooning in our virtualization environment) and so.

You can use the developer tools in your browser to try to track what responses are coming, but if the sagenb log isn't showing anything unusual, I'm not sure what else to say.
