Seems still being unable to login: "Failed to login to 8888"

yarikoptic commented 11 years ago

I am running ipython 0.13.2 notebook server... I wonder how could I trigger EIN to provide more details so you could troubleshoot it, in case it works for you -- any directions would be useful. EIN v0.2.0-59-g203ff99

How did you login? M-x ein:notebooklist-login? http://tkf.github.io/emacs-ipython-notebook/#ein:notebooklist-login

I wonder how could I trigger EIN to provide more details

You can start from M-x ein:dev-bug-report-template :) Fill the section and paste it in the comment.

Check list

[X] I read "Avoid standard Emacs traps" section in https://github.com/tkf/emacs-ipython-notebook/blob/master/CONTRIBUTING.md
[X] I checked that IPython works with the browser interface.
[X] I checked that the problem was not due to badly compiled files. Removing *.elc files from source directory of EIN and its dependencies did not solve the problem.
[X] I checked that the libraries are loaded from intended place. (You can check the location in the "System info" section below)

Description of the problem you have

Steps to reproduce the problem

$PWD/lisp/zeroein.el
Enter Get "ein: [error] Error (error) while opening notebook list at the server 8888."
M-x ein:notebooklist-login Enter enter password -- get "Failed to login to 8888"

Expected output

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

Your IPython configuration

What is your IPython version? (run ipython --version): 0.13.2
How do you start IPython? (e.g., ipython notebook --port 9999):

ipython notebook --pylab=inline

What is your IPython notebook port number or URL?:

8888

I installed IPython 0.13.2 and tried to reproduce your problem but couldn't. Here is my procedure:

ipython profile create eintest
ipython notebook --port 9999 --profile eintest --NotebookApp.password='sha1:******'

Then in another terminal:

cd PATH/TO/EIN
lisp/zeroein.el

Then in the opened Emacs:

C-g
M-x ein:notebooklist-login RET 9999 RET
M-x ein:notebooklist-open RET

Your profile might contain some stuff that EIN does not support. So, can you create a new profile to localize the problem?

Also, can you check installed version of IPython dependencies, especially tornado? Updating it could help you. I checked with these versions:

% pip search ipython tornado pyzmq jinja2 | grep -B1 INSTALLED
ipython                   - IPython: Productive Interactive Computing
  INSTALLED: 0.13.2 (latest)
--
Jinja2                    - A small but fast and easy to use stand-alone template engine written in pure python.
  INSTALLED: 2.6 (latest)
--
pyzmq                     - Python bindings for 0MQ
  INSTALLED: 13.1.0 (latest)
tornado                   - Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.
  INSTALLED: 3.0.1 (latest)

FWIW -- here are the versions of dependencies you have mentioned:

ii  ipython01x                      0.13.2-1~nd70+1      all                  enhanced interactive Python shell
ii  python-jinja2                   2.6-1                amd64                small but fast and easy to use stand-alone template engine
ii  python-tornado                  2.3-2                all                  scalable, non-blocking web server and tools
ii  python-zmq                      2.2.0-1              amd64                Python bindings for 0MQ library

so yes -- some of them are dated ... but I wonder if I could really troubleshoot this case - e.g. get more information from ein on what actually went wrong?

yarikoptic commented 10 years ago

aha -- it might be related also to have ipython server not listening on localhost but rather on some other interface -- in my case 10.0.0.1. So if I enter https://10.0.0.1:8888 then ipython kernel actually reacts and spits an error:

WARNING:root:SSL Error on 7: [Errno 1] _ssl.c:504: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca

Similar situation happens if I run similar build of ipython in Debian sid chroot (so dependencies are freshier). It is all I guess because ipython's SSL certificate is not signed by any known ca... but in a regular browser I just acknowledge all the security hazard associated with using ipython's certificate and proceed forward with authentication -- no such error is spitted out I believe.

tkf commented 10 years ago

I guess you should tell Emacs and curl to ignore CA but I don't know how to... Or maybe you can kind of port forward 10.0.0.1:8888 to 127.0.0.1:8888?

eefire commented 9 years ago

For me (similar setup, server listening on a non-localhost interface), this solves the issues:

$ echo insecure >> ~/.curlrc
