Execute cell when using SSH: ein: [warn] Kernel is not ready yet! (or closed already.)

davidpham87 commented 6 years ago

Check list

[x] Read the "Avoiding Common Emacs Traps" section in https://github.com/millejoh/emacs-ipython-notebook/blob/master/CONTRIBUTING.md
[x] Does IPython works from the web browser?
[x] Confirm the problem was not due to badly compiled files by removing all the *.elc files from source directory of EIN and its dependencies.
[x] Confirm that the libraries are loaded as expected and are at the required version. (You can check the location in the "System info" section below)

Description of the problem you have

Hello,

I am using EIN through a AWS server and recently I can't execute any cell anymore in any notebook anymore.

Steps to reproduce the problem

Create ipython notebook over an instance on network.
Launch jupyter notebook and connect to it with ein.
Execute any cell in the notebook.

Expected output

Execute the cell as in a local notebook.

Your EIN configuration (in .emacs.d/init.el or somewhere else)

  (setq request-curl-options '("--insecure"))
  (setq ein:console-args
  '((8000 . '("--ssh" "aws-jupyter" "--simple-prompt"))
    (default . "--simple-prompt"))
    ein:console-security-dir "~/jupyter_security")

Your IPython configuration

What is your IPython version? (run ipython --version): jupyter 4.4.0
How do you start IPython? (e.g., ipython notebook --port 9999): jupyter notebook --port=8888
What is your IPython notebook port number or URL?: 8888

Additional information (if any)

It was working until a few months ago.

Note: I tested it using the spacemacs environment and I used it on two different computers and get the same undesired behavior.

millejoh commented 6 years ago

So, I set up a jupyter notebook server on an AWS instance using a cert file and password. Believe me, no one was more surprised than I when everything worked the way it should. I was able to log in from my local windows machine and do all the normal notebook things.

This makes me think there is a configuration issue.

Are you able to log in and view the notebooklist buffer? What are the contents of the ein:log-all and, if you are able, the messages emitted by jupyter when you try to open a notebook and execute a cell?

davidpham87 commented 6 years ago

Dear @millejoh,

Thanks a lot for your swift answer. I can log in and read any notebook. My issue is when I try to execute any cell.

Here is the content of ein:log-all:

julienchastang commented 6 years ago

Maybe related to a similar problem, though I am not seeing any websocket errors in your output. Question for @davidpham87, the Jupyter server is running on AWS but the logs show localhost. Are you also running Emacs/EIN on AWS rather than from a local emacs session?

davidpham87 commented 6 years ago

@julienchastang I am not sure if I understand correctly the question, but I forwarded the port on the server jupyter notebok --port=8888 to localhost:8000, which could be the reason why it is written localhost.

I tried to debug the elisp code and the function returning if a kernel is open or not (the function returns nil).

millejoh commented 6 years ago

The port forwarding is probably causing the problem - EIN is writing an auth cookie tagged for the localhost:8000 URL, but jupyter may be expecting a cookie tagged with the url:port of the AWS instance. If you were able to see the log of the jupyter server running in debug mode (start via jupyter notebook --debug) it might give some more details in this respect.

It would be good to know how the web browser client reconciles all this, and maybe I could recreate it in EIN. To be honest, thinking about this gives me a headache...

davidpham87 commented 6 years ago

So I tested without the forwarding to localhost, so connecting directly to the ip with amazon.com:8888 at the end. However, I still had the issue. Please find below the output of jupyter notebook --debug.

[Edit]: I don't know if this is relevant, but I decided to open emacs25 in the terminal directly from the remote server and their, whenever I try to connect to the notebook, there is a *Network Security Manager* asking me to continue connecting. If I accept, the notebook is working fine. However, this message is not sent when I use on my local computer.

Can you tell me which steps you did for connecting and running your notebook on aws? Thanks a lot for your support!

millejoh commented 6 years ago

Below is the config file I'm running on the EC2 instance. The instance is running Ubuntu and has jupyter notebook v5.6.0 installed.

It was working, and now it isn't, but it doesn't quite feel like an ein issue so much as a configuration problem. I'll write more if I can get everything working again.

millejoh commented 6 years ago

At the bottom of #163 I've tried to describe a bit what EIN is doing when it opens a websocket connection. One thing you can try doing is call M-x url-cookie-list in the notebook buffer that is not executing and see if the cookies that appear there have the correct host name and port.

Note there also might be an issue with the certificate for the https connection, especially if the certificate is self-signed. In that case you need to ensure curl is called with the --insecure argument.

davidpham87 commented 6 years ago

I set the --insecure argument from request-curl-option already. I can connect to the remote notebooks and navigate in the tree, open a notebook, but I can't execute its content :-(

As far as the cookies, I see two lines which are really similar to what you showed in the #163, thanks for the comments by the way! I tried also with GCE and get the same problem, so probably not an issue from the provider.

I can tell that this function returns nil and this is what makes the ein:execute-kernel stopping:

(defun ein:websocket-open-p (websocket)
  (eql (websocket-ready-state (ein:$websocket-ws websocket)) 'open))

When I tried to debug using debug-on-entry on ein:execute-kernel, I got (long text)

Do you mind sharing the cookies? What version of curl are you using? Also, if you are feeling adventurous, could you set websocket-debug to t and then look for what appears in the info buffer for the websocket. The buffer is *websocket URL debug* where URL is the URL of the connection.
