I am running a sample code which just list down the networks available.

please find below code 

#!/usr/bin/python
from os import environ as env
import keystoneclient.v2_0.client as ksclient
from neutronclient.v2_0 import client as neutronclient
keystone = ksclient.Client(auth_url=env['OS_AUTH_URL'],
    username=env['OS_USERNAME'],
    password=env['OS_PASSWORD'],
    tenant_name=env['OS_TENANT_NAME'])
endpoint_url = keystone.service_catalog.url_for(service_type='network')
print endpoint_url
token = keystone.auth_token
neutron = neutronclient.Client(endpoint_url=endpoint_url, token=token)
neutron.list_networks()

But i am facing following error

Traceback (most recent call last):
  File "./list_network.py", line 8, in <module>
    tenant_name=env['OS_TENANT_NAME'])
  File "/usr/lib/python2.6/site-packages/keystoneclient/v2_0/client.py", line 147, in __init__
    self.authenticate()
  File "/usr/lib/python2.6/site-packages/keystoneclient/utils.py", line 318, in inner

    resp = self.get_raw_token_from_identity_service(**kwargs)
  File "/usr/lib/python2.6/site-packages/keystoneclient/v2_0/client.py", line 181, in get_raw_token_from_identity_service
    return plugin.get_auth_ref(self.session)
  File "/usr/lib/python2.6/site-packages/keystoneclient/auth/identity/v2.py", line 79, in get_auth_ref
    authenticated=False, log=False)
  File "/usr/lib/python2.6/site-packages/keystoneclient/session.py", line 430, in post
    return self.request(url, 'POST', **kwargs)
  File "/usr/lib/python2.6/site-packages/keystoneclient/utils.py", line 318, in inner
    return func(*args, **kwargs)
  File "/usr/lib/python2.6/site-packages/keystoneclient/session.py", line 346, in request
    raise exceptions.from_response(resp, method, url)
keystoneclient.openstack.common.apiclient..exceptions.Unauthorized: Could not find project, ESS. (HTTP 401)

When i rune "neutron net-list" from the command line it works absolutely fine.

Has anything needs to be changed on the keystone to accept API calls ? am i missing anything. I checked the environment variables. They are set corrctly in both the cases .

check whether the neutron service is up, also check you are running script where neutron is running

It seems that the script isn't passing the tenant name correctly. Could you try to print the query to stdout instead to sending it and see if everything is correct?

Here is a quick update i modified my code to use v3 and now my keystone client is getting created. But now i am stuck at keystone.service_catalog.url_for(service_type='network')

is there a new error or something with the new code or just the same error?

can you try this to see what happens?

endpoint_url = keystone.service_catalog.url_for(service_type='network', endpoint_type='publicURL')
