Pyhaystack is a module that allow python programs to connect to a haystack server project-haystack.org. Connection can be established with Niagara Platform running the nhaystack, Skyspark and Widesky. For this to work with Anaconda IPython Notebook in Windows, be sure to use "python setup.py install" using the Anaconda Command Prompt in Windows. If not, module will be installed for System path python but won't work in the environment of Anaconda IPython Notebook. You will need hszinc 1.3+ for this to work.

Authentication problem with Niagara 4.6 #67

Closed tybeady closed 5 years ago

tybeady commented 6 years ago

I have been getting the following error when trying to connect to a JACE 8000:

File "C:\ProgramData\Anaconda3\lib\site-packages\pyhaystack\client\ops\grid.py", line 133, in _do_auth_failed raise AuthenticationProblem()

AuthenticationProblem

I have set up the user as a basicHTTP user but I still can't connect. After watching the traffic it looks like the JACE sends back a Hello handshake but then pyhaystack just gives up and tries again.

I don't have access yet to 4.6..... but here is what I do with 4.4 The user I use is configured with digest using all rights I need (html5 web Profile) and for get_bql to work, we need the hx_view checked in the web profile (going from memory here... may be slightly different name.

Then I use this script to log in : 

from pyhaystack.client.niagara import Niagara4HaystackSession
session = Niagara4HaystackSession(uri='https://192.168.1.149',
                                 username=user,
                                 password=password,
                                 http_args={'debug':True, 'tls_verify':False, 'insecure_requests_warning':False})

Hope it'll help

@tybeady It work on my side with 4.6 using SSL. Is this still a problem for you ?

Really, we should pull our fingers out and come up with a more helpful error message… when I wrote that code I didn't bother trying to add code to diagnose it further and it does make things difficult at times.

The http_args={'debug': True}, coupled with setting up logging (do import logging; logging.basicConfig(level=logging.DEBUG) prior to attempting to connect) can help diagnose a lot of issues.
