Spyder Crashes on Windows During Remote Kernel Connection

This issue occurs for me on both spyder 2.3.4 and 2.3.5.2. I am running Windows 8.1 (x64), with Python 3.4.3 installed.

SSH keys are configured such that no password is needed to connect to server

From Git-Bash

ogi@OGI-DESKTOP ~/.ssh
$ ssh ogi@ubuntu

I can confirm a connection with Paramiko (note: I had to apply some commits from a fork due to a known_hosts issue here: https://github.com/paramiko/paramiko/pull/473 )

Generating the kernel on my server:

ogi@ubuntu:~$ ipython kernel --ip='*'
NOTE: When using the `ipython kernel` entry point, Ctrl-C will not work.

To exit, you will have to explicitly quit this process, by either sending
"quit" from a client, or using Ctrl-\ in UNIX-like environments.

To read more about this, see https://github.com/ipython/ipython/issues/2049


To connect another client to this kernel, use:
    --existing kernel-4481.json

In my working directory, I have my kernel-4481.json file with the following contents:

{
  "signature_scheme": "hmac-sha256",
  "control_port": 43208,
  "stdin_port": 42048,
  "ip": "0.0.0.0",

Suggestions?

Just wondering if there is a way to connect to Docker Linux Ipython running, I have similar error connection.

Thanks

I am trying to start a remote IPython process (kernel) in remote server and connect Spyder to it. But still fighting with this!!!

The remote server is Ubuntu server running as Virtual Machine (VirtualBox). The IP is 10.0.2.15.

Local Spyder is running on Windows 7. Version is 2.3.5.2.

I define port forward in VirtualBox from 127.0.1.1:22 to 10.0.2.15:22, by which I can use PuTTY to connect to the remote server by SSH.

Anaconda is installed in the remote server. To start a ipython kernel on the remote server, I use:

I copy the kernel-remote.json file from the remote server to my local Windows.

Then in my local Spyder, I add the remote kernel as:

Then when I click OK to connect, the python crashes with the error message:

Then I open a command window, try to connect to the remote ipython kernel by:

I get the error message below:

Now I am confused it is the problem from Spyder, or IPython, or the configuration of remote server. I lose my direction where to go. Using the remote kernel is very important in my project, so Please help me!!!
