Dear jupyter developers.
I am the manager of a large HPC system and users have requested and
received a central jupyter installation.
Today two users alerted me to two different issues:
(a) the ports are not user specific, but system specific
(b) with these ports being system specific there is a security issue:
without being alerted or identified the system asks for the user's
password on attaching to the notebook
and if no password is set in the jupyter setup, any user can access
that notebook.
The former is troublesome, as different users do not know what ports are
already used. This can lead to confusion. Is there a means of controlling
this on system level?
The latter (b) poses a security risk. Is there a means of enforcing a
password or linking the jupyter password to the user's system password?
I am a total newbie of using jupyter and if there are answers in the
documentation to the questions, could you please point me to them?
If not, are there possible answers?
