Python SDK ABC example — not working (SSL: UNKNOWN_PROTOCOL error)

benridescout — Tue, 23 Jun 2015 14:58:37 GMT

New to Splunk and Python... Trying to get up and running with the Python SDK. Installed the SDK for Python libraries, and modified the splunk-sdk-python-master/examples/abc/a.py file with values that work to log in to our Enterprise installation via the web:

import httplib 
#etc

HOST = "54.xxx.xxx.xxx"
PORT = 8000
USERNAME = "my-username"
PASSWORD = "my-password"

#etc etc

When I run this from the terminal with

python a.py

I get the following error:

Traceback (most recent call last):
File "/Users/ben/Desktop/splunk-sdk-python-master/examples/abc/a.py", line 38, in <module>

    self._sslobj.do_handshake()

Can anyone suggest what I might be doing wrong? Thanks!

Can you please copy some code from a.py file, specially some code around line 38 (few lines above and below).

File "/Users/ben/Desktop/splunk-sdk-python-master/examples/abc/a.py", line 38, in
connection.request("POST", "/services/auth/login", body, headers)

The rest of the file is as downloaded from the SDK for Splunk. Here's the file in its entirety, as used, except for the server/login credentials:

Make sure you are using the right port for your instance.

Re: Python SDK ABC example — not working (SSL: UNKNOWN_PROTOCOL error)

benridescout — Tue, 23 Jun 2015 17:03:36 GMT

Ah, OK. The port 8000 works for accessing the instance through the web interface. Should I use a different port for access via the Python SDK?

vinitatsky — Tue, 23 Jun 2015 17:04:43 GMT

Can you try 8089

Re: Python SDK ABC example — not working (SSL: UNKNOWN_PROTOCOL error)

jnicholsenernoc — Tue, 23 Jun 2015 17:08:13 GMT

Should be the Splunk management port, 8089

Re: Python SDK ABC example — not working (SSL: UNKNOWN_PROTOCOL error)

benridescout — Tue, 23 Jun 2015 17:09:21 GMT

OK, I tried port 8089—it still fails at line 38, but the error message is now:

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)

Re: Python SDK ABC example — not working (SSL: UNKNOWN_PROTOCOL error)

jnicholsenernoc — Tue, 23 Jun 2015 19:58:14 GMT

Are you using a self-signed cert? Keystore up to date?

Re: Python SDK ABC example — not working (SSL: UNKNOWN_PROTOCOL error)

I don't know—let me find out. Thank you for the suggestion!

PORT = 8000

That is the wrong port.
The SplunkD Management port is 8089 by default (as per what is actually in the a.py example).

PORT = 8089

OK, folks—I think I figured a few things out here. Thank you to all of you who suggested using port 8089 instead of 8000. That was certainly part of the problem.

The two other problems I've identified are:

The ABC examples, at least (I don't know about the rest of the python SDK), don't seem to work under Python v2.7.10. When I tried running the c.py example (with port 8089) under Python v2.7.8, I was able to get it to work—it connects and returns the list of installed apps as expected.
The a.py example, however, seems to have another problem. With the same login credentials, port, and in the same environment, it returns this error:

(splunksnake)Bens-MacBook-Pro-2:~ ben$ python /Users/ben/Desktop/splunk-sdk-python-master\ 2/examples/abc/a.py
Traceback (most recent call last):
File "/Users/ben/Desktop/splunk-sdk-python-master 2/examples/abc/a.py", line 45, in
sessionKey = ElementTree.XML(body).findtext("./sessionKey")
File "/Users/ben/anaconda/envs/splunksnake/lib/python2.7/xml/etree/ElementTree.py", line 1301, in XML
return parser.close()
File "/Users/ben/anaconda/envs/splunksnake/lib/python2.7/xml/etree/ElementTree.py", line 1654, in close
self._raiseerror(v)
File "/Users/ben/anaconda/envs/splunksnake/lib/python2.7/xml/etree/ElementTree.py", line 1506, in _raiseerror
raise err
xml.etree.ElementTree.ParseError: no element found: line 1, column 0

Using curl from the terminal, I can see the Splunk instance is returning a sessionKey, so perhaps there is an issue with the way that key is being handled.

Anyway, thanks again for your help sorting this out!

I'm getting exactly the same issue. From 2.7.10 not working, downgraded to 2.7.6, to a.py not working and c.py working. Ports and credentials checked.
