I used to use notebook sagenb for teaching purposes.
Each student had a login and password to work on the same server.
I ran into several internal server errors 500 using it. so I though since it seems that jupyter notebook is more recommended I should try and switch to it.
However, I am concerned because I am not sure it allows the same type of multi-users server.
Hint from jupyter notebook login page that points to
https://jupyter-notebook.readthedocs.io/en/stable/public_server.html
tell me that it might not.
So the questions are:
1/ with "sage -n jupyter --ip='*'" is it possible to have 16 or so students connecting to the same server and working on similar worksheets (as it seemed to work rather smoothly for sagenb)?
2/ if not, is there another way to have sage use jupyter notebook for multi users?
3/ if not, is an install of jupyterhub or sagemathcloud reasonnable with no particular sysadmin skill?
4/ if not is there anything else I should try?
5/ if not, do some of you have experience of sagenb under sage 8.3 usability?
Installing sagemath on all computers is not an option for me at the moment.
Best regards,
b
PS : my sagemath on a debian 9 server compiled from source (I used to use debian packages but though it might work more smoothly with install from source)bb16Thu, 11 Oct 2018 09:30:33 -0500http://ask.sagemath.org/question/43919/jupyter tutorialhttp://ask.sagemath.org/question/45346/jupyter-tutorial/ My university department is updating the instance of sagemath that we use to 8.6. This will use the new Jupyter interface. I have two questions about the upgrade:
1) The old instance of sage we are running has many users each with their own notebooks. How do we migrate the multi-user environment to sagemath with Jupyter?
2) All of our sagemath users will need to migrate to using Jupyter. Is there a good tutorial for using sagemath in Jupyter? The [http://www.sagemath.org/help.html](http://www.sagemath.org/help.html) documentation and tutorials in sagemath's website still are referencing the old notebooks.
thanks

I am a systems administrator at University of Southern California and I am attempting to include SageMath-7.6 in our lab image (around 400 computers, thousands of students). Students log in with non-administrative active directory accounts,thus when launching SageMath-7.6 they get a "read-only" error. How significantly does this affect their use of the application? If I chmod -R 777 on the SageMath-7.6.app this corrects the issue, but (security issues aside) how does this impact other users that will be using the application and making changes to it? If application changes and configurations are not being stored in the user's profile then how does the application isolate changes from multiple users?
Thanks in advance for your assistance.dkaurlotSun, 20 Aug 2017 05:27:52 -0500http://ask.sagemath.org/question/38589/Installing SageMath for multiple users?http://ask.sagemath.org/question/37505/installing-sagemath-for-multiple-users/ I have been asked to look into installing SageMath on a server for use by multiple users (I am a sysadmin and not a mathematician). I had initially looked into this a couple of years ago, but then priorities were changed.
From the previous occasion, I recall that SageMath installation is generally from a tarball (or a possibly quite fearsome compilation from source), and that the SageMath notebook interface runs in the user's web browser. I seem to recall then that it would be difficult or impossible for more than one end user to run SageMath, as, when it opens a web browser, it is not aware of there actually being different end users on a multi-user server computer and the notebook interface would not be able to cope with this (without somehow running multiple web interfaces on separate network ports?). The SageMath documentation also rather seems to assume the use case of an individual user with sysadmin powers installing SageMath on their own personal computer for their own stand-alone personal use (if there is specific documentation about setup for multiple users, I have not yet found it, unfortunately).
Is it (easily) possible to install SageMath on a (Linux) server for multiple end users to be able to use it via the notebook interface, or would it realistically be substantially easier to consider the use of the SageMath Cloud service instead?
Thank you for any advice.dave559Thu, 04 May 2017 05:42:58 -0500http://ask.sagemath.org/question/37505/Virtual machine appliancehttp://ask.sagemath.org/question/9824/virtual-machine-appliance/The sage appliance wiki suggests editing the sage user .bash_profile as follows
"and replace the line
>
> ./sage -notebook interface=\'\' port=8000 open_viewer=False require_login=False
>
with
>
> ./sage -notebook interface=\'\' port=8000 open_viewer=False require_login=True secure=True
however the 5.6 appliance does not have thses lines but merely alias=sage-hg
Where do I alter the notebook launch to make the appliance launch for other users.
