I run ipython 0.12.1 on Ubuntu 12.04. You can run it in browser using notebook interface by running:

ipython notebook --pylab

Configuration files can be found in ~/.config/ipython/profile_default/. It seems that connection parameters for every kernel is placed in ~/.config/ipython/profile_default/security/kernel-4e424cf4-ba44-441a-824c-c6bce727e585.json. Here is the content of this file (new files are created as you start new kernels):

{
  "stdin_port": 54204, 
  "ip": "127.0.0.1", 
  "hb_port": 58090, 
  "key": "2a105dd9-26c5-40c6-901f-a72254d59876", 
  "shell_port": 52155, 
  "iopub_port": 42228
}

It’s rather self-explanatory but how can I set a server that would have a permanent configuration, so I can use notebook interface from other computers in the LAN?

    If you are using an old version of the notebook, the following could still apply. For new versions see the other answers below.

    Relevant section of the IPython docs

    The Notebook server listens on localhost by default. If you want it to be visible to all machines on your LAN, simply instruct it to listen on all interfaces:

    ipython notebook --ip='*'

    Or a specific IP visible to other machines:

    ipython notebook --ip=192.168.0.123

    Depending on your environment, it is probably a good idea to enable HTTPS and a password when listening on external interfaces.

    If you plan on serving publicly a lot, then it’s a also good idea to create an IPython profile (e.g. ipython profile create nbserver) and edit the config accordingly, so all you need to do is:

    ipython notebook --profile nbserver

    To load all your ip/port/ssl/password settings.
