jupyter notebook not starting - new Mini-conda install

I have a new Miniconda install on openSUSE linux 42.3

I’ve installed jupyter and various other bits, and jupyter notebooks won’t start without extra parameters:

> jupyter notebook --no-browser
Traceback (most recent call last):
  File "/home/admin/Anaconda3/envs/udacity-nd101/bin/jupyter-notebook", line 11, in <module>

    sock.bind(sockaddr)
OSError: [Errno 99] Cannot assign requested address

I’ve added:

c.NotebookApp.port = 8888
c.NotebookApp.ip = '127.0.0.1'

to ~/Anaconda3/envs/env-name/lib/python3.6/site-packages/jupyter_core/tests/dotipython_empty/profile_default/ipython_notebook_config.py and that didn’t help.

It runs OK if started: jupyter notebook --ip='127.0.01' --no-browser

Should I put these lines somewhere else or is this a defect?

OK. Wrong config files.

Added the settings to ~/.jupyter/jupyter_notebook_config.py (after generating it) and it now works without extra command line parameters.

But … there’s still a defect somewhere.

I get pretty much the same error message on Antergos. Runs fine when started with jupyter notebook --ip='127.0.0.1'

I noticed something interesting.

jkbr:~/ $ ssh jkbr@localhost                                                                                          
ssh: connect to host localhost port 22: Cannot assign requested address
# looks like it doesn't work
jkbr:~/ $ ssh jkbr@127.0.0.1

# Seems like my firewall is doing its job

It seems to me that this issue doesn’t have anything to do with jupyter or miniconda but localhost not being properly set on the system. This seems like something with basic knowledge about this kind of stuff should be able to fix pretty easily, however I’m not one of those people.
