error 403 with ein over proxy #76

Open sam-s opened 3 years ago

sam-s commented 3 years ago

according to @dickmao in https://github.com/tkf/emacs-request/issues/193#issuecomment-728884166, the bug described in https://github.com/tkf/emacs-request/issues/193 and https://github.com/millejoh/emacs-ipython-notebook/issues/754 is coming from websocket. Please let me know if I could be of any assistance in debugging. thank you.

This isn't really possible for me to debug, AFAICT. The websocket library offers a way to send headers. Those headers can be authentication headers. Websockets aren't going to cause authentication problems itself - that's the server's doing. It could be that the necessary info isn't coming over via websockets to the server. I can think of a few reasons for this.

  1. ein isn't sending the authentication information via the header. By tracing websocket-open you should be able to see the headers sent to the websocket library. Maybe ein has no way to do this, maybe it does, but you are doing it incorrectly. I'm not sure.
  2. websocket isn't correctly sending the header information ein provides. You can trace websocket-create-headers to verify that the headers are being created correctly, or perhaps try and snoop on the network traffic to see what is going on.
  3. You mentioned in another bug there's a proxy involved - it is possible that the websocket library and the proxy server have some incompatibility.
  4. It's possible that whatever you are connecting to expects some other form of authentication that websocket cannot provide. If it should be providing that according to the websocket spec, that's a bug, and something that I can fix.

Can you look at the above possibilities and let me know?

I can connect to the jupyter server using chrome; here are the headers:

ahyatt commented 3 years ago

Thanks for the response. What is interesting is that you have cookies for this site already in emacs. Do you know where those come from? Can you connect to the notebook in emacs with eww?

If this is an internal server for your organization, is there any chance you can ask what authentication they are expecting? Or if they have logs of when you access with websockets, to see what the problem is on the server side.

There's a few things here that could be interesting - what you can try to do is to add some of these headers to the websocket-open call in ein (I don't know if ein provides a good mechanism for you to do that, but if not you could perhaps use advise the websocket-open call to do this). You can try the various headers you see here, but to me the interesting one is upgrade-insecure-requests.

Thanks for the response.

Thank you!

What is interesting is that you have cookies for this site already in emacs. Do you know where those come from?

Yes, they are written by Emacs/curl. When I remove the local file ~/.config/emacs/request/curl-cookie-jar, ein:bnotebooklist-login asks me for the token (stored on the server in ~/.local/share/jupyter/runtime/nbserver-*.json and, after I enter it, never asks me again until the jupyter server is restarted (with the new token). Please see https://github.com/millejoh/emacs-ipython-notebook/issues/754#issuecomment-726109727 et al.

sam-s commented 3 years ago

Can you connect to the notebook in emacs with eww?

Sort of... I can "get in" using https://data-science.k8s.region-001.p-use-1.braze.com/tree/?token=XXXXX but the page does not show the actual list of notebooks because Jupyter Notebook requires JavaScript (and Emacs/eww does not support JavaScript for ideological reasons). When I try to access https://data-science.k8s.region-001.p-use-1.braze.com/notebooks/Untiled.ipynb directly, I get the same JavaScript message.

sam-s commented 3 years ago

If this is an internal server for your organization, is there any chance you can ask what authentication they are expecting?

this is the standard jupyter server:

jupyter notebook --port=8080 --ip=0.0.0.0 --allow-root \
     --NotebookApp.iopub_data_rate_limit=1.0e10 \
     --NotebookApp.iopub_msg_rate_limit=1.0e10

with token authentication

Or if they have logs of when you access with websockets, to see what the problem is on the server side.

here is the relevant part of the jupyter server log:

[W 12:15:34.907 NotebookApp] Couldn't authenticate WebSocket connection
[W 12:15:34.908 NotebookApp] 403 GET /api/kernels/17a98983-0ab0-489a-80e9-8e5498fbb74d/channels?session_id=e21e701d-c904-4ddd-9e97-fb1e906c51eb (100.108.90.236) 2.21ms referer=None

Interesting, thanks for sharing. Let's summarize - and let me know if anything I say is wrong.

  1. You get a 403 error with ein over a proxy.
  2. Most people using ein don't get this error.
  3. The websocket headers are probably fine.
  4. Your jupyter notebook isn't unusual.

My guess is that it has to be a proxy issue - that seems to be the only difference from normal. Is there any relevant info on the proxy you are using you can share? I don't know much about proxies, but I do know that websocket doesn't have any special support for them.

Also, have you seen https://github.com/jupyter/notebook/issues/3389? It seems very similar to your issue.

could be - my jupyter works with chrome & firefox but not with ein.

There is a glimpse of hope - when I append &token=XXX to the url that I pass to websocket-open, everything works just fine.

Same error on ubuntu 18.04 jupyter 6.1.6

@sam-s Interesting that the token works. I wonder if this means that ein should be setting it. The websocket library is agnostic about such things. It seems like, from the headers you have provided, that ein is asking for it but not passing it along to the websocket library. Does that sound plausible to you?

@cw1427 Can you also try to manually append the token in the same way described above to see if that solves your problem? Is there anything unusual about your jupyter installation?
