iPython ssh from Windows qtconsole to a remote iPython kernel

I want to run an iPython kernel on a Linux box and then connect to it remotely on a windows machine. The ipython kernel works fine and I can connect a qtconsole to it locally on the Linux box. On Windows I have installed ipython and paramiko as its ssh client. I run the following command on Windows 7 x64 cmd

D:\...\.ssh>ipython qtconsole --IPythonConsoleApp.sshserver='user@hostname:22' --IPythonConsoleApp.sshkey='myKey' --IPythonConsoleApp.password='1234'

I get the following error:

[IPythonQtConsoleApp] Could not setup tunnels
Traceback (most recent call last):
  File "C:\Python27\lib\site-packages\IPython\frontend\consoleapp.py", line 289, in init_ssh

  File "C:\Python27\lib\site-packages\IPython\lib\kernel.py", line 245, in tunnel_to_kernel
    if tunnel.try_passwordless_ssh(sshserver, sshkey):

  File "C:\Python27\lib\site-packages\paramiko\client.py", line 493, in _auth
    raise saved_exception
SSHException: not a valid DSA private key file

The key is even created with RSA.

Has anybody had a success in connecting remotely from a Windows machine to a remote ipython kernel?

You say

The key is even created with *R*SA.

but

SSHException: not a valid *D*SA private key file

RSA and DSA are different algorithms.

Either create a DSA private key file, or configure ipython to use RSA.

(I am not familiar with ipython, so cannot advise on the specifics. Sorry.)
