error of connecting to remote IPython notebook server via ssh tunnel

This is what I did:

   remote.server$ ipython notebook --no-browser --port=8889
   local$ ssh -v -N -L localhost:8888:localhost:8889 remote.server

Then I tried to launch it with localhost:8888. But on the remote server, there is this error:

[E 21:41:40.853 NotebookApp] Uncaught exception in write_error
    Traceback (most recent call last):

        "application to use %s" % (name, feature))
    Exception: You must define the 'cookie_secret' setting in your application to use secure cookies

And nothing showed up in the webpage. I did the same thing for another server and it worked. What is the problem for this server and how to fix it?

I am using virtual environment from miniconda. The versions are:

ipython                   3.2.1                    py27_0  
ipython-notebook          3.2.1                    py27_0  
jinja2                    2.7.3                    py27_1
tornado                   4.2                      py27_0  
zeromq                    4.0.5                         0

I've resolve this problem by reading Jupyter notebook official documents.

1.run

    jupyter notebook --generate-config

2.Then you will get

    jupyter_notebook_config.py

in '.jupyter'.

3.open 

    jupyter_notebook_config.py

and write 

    c.NotebookApp.cookie_secret = b'anything'

and it will work

Ok, so I looked into it a bit, seems like the automatic generation of the cookie secret somehow fails. What you can do to resolve this issue though, is to run:

ipython profile create

And then open this file (it shows you the exact location):

[ProfileCreate] Generating default config file: '/home/username/.ipython/profile_default/ipython_config.py'
...

with your favorite text editor. At the end of the file append:

c.NotebookApp.cookie_secret = b"your secret that should not be on the internet"

And it should work.

If the browser still won't load the page, force refresh with Ctrl+F5
