Having multiple users be able to log into jupyterhub

[Grant Herman]

So I am relatively new to Jupyterhub, so I apologize for my ignorance. 

I have set up Jupyterhub and I am able to log in with the system user that I am logged in to my computer with. However, when I tried to log in with another system user name I got this error:

[I 2015-12-14 15:22:32.833 JupyterHub spawner:363] Spawning jupyterhub-singleuser --user=grant --port=49311 --cookie-name=jupyter-hub-token-grant --base-url=/user/grant --hub-prefix=/hub/ --hub-api-url=http://localhost:8081/hub/api --ip=localhost

Failed to set groups [Errno 1] Operation not permitted

[E 2015-12-14 15:22:32.848 JupyterHub orm:382] Unhandled error starting grant's server: Exception occurred in preexec_fn.

How can I allow for multiple users to have access to jupyterhub, even if jupyterhub is not being started on that user's account?

[Brian Granger]

I think the issue may be the following.

What user did you start jupyterhub as? To log in as other users, you
would need to start it as root.

The other thing to look at is the Authenticator.whitelist
configuration setting. It either needs to be empty (allow all users)
or contain the set of usernames that should be allowed.

Let us know if that helps.

That is what I thought! ok thank you!!

[Grant Herman]

Hey so I made all of this changes and I still and getting a 500 internal error. Do you know what else it could be?

I have also been getting this error

  warn("IPython.utils.traitlets has moved to a top-level traitlets package.")

when jupyterhub starts, could that mess things up? 

[MinRK]

It’s possible. What versions of packages do you have (pip list)?

Here are my version:

 

ipython (4.0.1)

ipython-genutils (0.1.0)

jupyter-client (4.1.1)

jupyter-core (4.0.6)

jupyterhub (0.4.0.dev0

[Grant Herman]

I will also get the following error:

  FileNotFoundError: [Errno 2] No such file or directory: 'jupyterhub-singleuser'

[MinRK]

If you don't have `jupyterhub-singleuser`, then either JupyterHub
installed somewhere not on your PATH, or didn't successfully install.
I think you want to install the `notebook` package as well:

pip install notebook

What do you get for `which jupyterhub`?

[Grant Herman]

I get this after which jupyterhub:

alias jupyterhub='/usr/local/bin/jupyterhub'

/usr/local/bin/jupyterhub

[Grant Herman]

I added jupyterhub to the $PATH and I have been getting this error: 

  

raise DistributionNotFound(req)

pkg_resources.DistributionNotFound: jupyterhub==0.4.0.dev0

[MinRK]

That suggests that the current version of JupyterHub is not installed
for the Python that's executing the script. You can check things like
this with `head $(which jupyterhub)`, and probably fix it with a `pip
install -e /path/to/jupyterhub`.

[Grant Herman]

so I run that head $(which jupyterhub) command and get:

# EASY-INSTALL-DEV-SCRIPT: 'jupyterhub==0.4.0.dev0','jupyterhub'

__requires__ = 'jupyterhub==0.4.0.dev0'

__import__('pkg_resources').require('jupyterhub==0.4.0.dev0')

__file__ = '/home/centos/jupyterhub/scripts/jupyterhub'

exec(compile(open(__file__).read(), __file__, 'exec'))

So then I try to pip install the __file__, but I get this:

/home/centos/jupyterhub/scripts/jupyterhub should either be a path to a local project or a VCS url beginning with svn+, git+, hg+, or bzr+

[MinRK]

Where’s the #! line in the juptyerhub script? That should be the first line.

Sorry, the path you give to pip should the the repository, not the
script: pip install -e /path/to/jupyterhub/repo

Thanks for your help! I figured out the problem. So for each user I needed to clone the jupyterhub repo and then do the pip3 install requirements. Once I did that, I am able to log in with different users.

That’s not generally necessary. Can you perhaps share your config
and/or paths for installation, etc.? If you are doing pip install -e
(as opposed to just pip install), you do need to make sure that the
jupyterhub repo is readable by all your users.

So I have not been using a config file and I have exported the path of jupyterhub in the ~/.bash_profile. However, I have been having the same issue as before. Where would I have to download the jupyterhub so it will accessible for all system users?

The script used to start the single-user servers is inside the JupyterHub package. This needs to be read by the users to start their single-user server. If the users cannot read the JupyterHub package's location, they cannot read the script they need to run.

so my local jupyterhub is at /root

the jupyterhub is downloaded at /usr/local/bin/jupyterhub

head $(which jupyterhub) yields:

#!/usr/local/bin/python3.4

# EASY-INSTALL-DEV-SCRIPT: 'jupyterhub==0.4.0.dev0','jupyterhub'

__requires__ = 'jupyterhub==0.4.0.dev0'

__import__('pkg_resources').require('jupyterhub==0.4.0.dev0')

__file__ = '/root/jupyterhub/scripts/jupyterhub'

exec(compile(open(__file__).read(), __file__, 'exec'))

I am still getting the same error everytime I try to log onto jupyterhub and I am not sure why. I dont know where I should download jupyterhub so all the system users will have access.

[MinRK]

In order to start their servers, all users need to read the file that
is found by:

python3 -c 'import jupyterhub.singleuser; print(jupyterhub.singleuser.__file__)'

If you are installing with pip install -e, that’s the likely cause,
since that only installs references to files that may live elsewhere,
such as in your home (or root) directory, which may not be
world-readable. If you do a regular install (no -e), then it will copy
files to a system-readable location, such as /usr/local.
