> Problems that occurred and got solved along the way:
> • The tuturial on the web had some dead links to port the arch linux - SOLUTION: googled around and found an updated tutorial
> • Installed python >3 via pacman on the arch linux since it is default - SOLUTION: removed all python installs and used the "pacman -S python2 ipython2 python2-<package_name>" this meant that in order to initiate the notebook we had to run "ipython2 notebook --profile observer"
> • The notebook started on a wrong ip address (127.##..) which meant we couldn't see it - SOLUTION: changed the address in the notebook profile to 192.168.#.###
'Wrong' is relative. We start with not listening on external IP adress for security reason.
Hope you made it use https and password protected ! :-)
> • Changing the notebook profile was done via dropbox. Opened a config file and changed the settings and got it onto the arch linux by the command: "wget https:link.to.config/file.py". Finding the directory on the arch was a bit tricky until we discovered the "ipython2 locate" command. It would be great if there existed some easy way to edit the profile within a ipython session.??
A hack would be to use %load `profilefile` to set the next prompt as the `profilefile`
the use the `%%file profilefile` cell magic to re-write it on disk after editing.

`! command` ? or `%%bash` magic ? You don't have stdin (yet) in notebook so sudo will not be able to ask for pwd.
Sudo should have an option to give the password from command line, but be carefull to disable history before.

I think this will need IPython patches.
Happy you got it to work.
