Load Configuration File with Juniper PyEZ

I am trying to load override a config stored on the juniper device (vSRX) with PyEZ. The code looks like this
from jnpr.junos import Device
from jnpr.junos.utils.config import Config
dev = Device(host="x.x.x.x", user='user', password='pass').open()
with Config(dev, mode='private') as cu:
cu.load('load override minimal.conf', format='set')
cu.pdiff()
if cu.commit_check():
cu.commit()
When I run the script I get below error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/jnpr/junos/utils/config.py", line 534, in load
ignore_warning=ignore_warning)
File "/usr/local/lib/python2.7/dist-packages/jnpr/junos/utils/config.py", line 455, in try_load
raise ConfigLoadError(cmd=err.cmd, rsp=err.rsp, errs=err.errs)
jnpr.junos.exception.ConfigLoadError: ConfigLoadError(severity: error, bad_element: load, message: error: unknown command)
Can't find a solution to my problem. Any help is greatly appreciated!

If you are trying to load config from a local file (on junos device), you should use url option
Check for url in:
http://junos-http://junos-pyez.readthedocs.io/en/2.1.8/jnpr.junos.utils.html#jnpr.junos.utils.config.Config.load

Your cu.load() is wrong.

Unable to get twemproxy to work with Python redis

I installed nutcracker 0.4.0 and have this in the config:
redis:
listen: 127.0.0.1:22121
hash: fnv1a_64
distribution: ketama
auto_eject_hosts: true
redis: true
server_retry_timeout: 2000
server_failure_limit: 10
servers:
- 127.0.0.1:6379:1
Code:
>>> client = redis.StrictRedis(host='127.0.0.1', port=22121, db=1)
>>> client.set('a', 'b')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/sudheer/workspace/pvenvs/p2s/lib/python2.7/site-packages/redis/connection.py", line 137, in _read_from_socket
(e.args,))
redis.exceptions.ConnectionError: Error while reading from socket: ('Connection closed by server.',)
How can I get Twemproxy to work with redis-py?

I figured out the solution to my problem. Python redis client was sending SELECT command when the configuration had URL like: 127.0.0.1:6379?db=1. The db=1 triggers the SELECT command which is not supported by nutcracker. I changed it to db=0 and things work well now.

SUDS Exception Imported Schema Failed

I'm getting the error:
Exception: imported schema (http://www.w3.org/2001/XMLSchema) at
(http://www.w3.org/2001/XMLSchema.x sd), failed
when passing a Doctor (constructed with ImportDoctor) to the suds Client constructor.
I'm working on two Windows machines, both of them got the same version of suds installed, but only one of them rises the error above.
Could someone guide me here to know why this error rises?, so I can figure out what's missing on the machine where it happens?.
Thanks in advance!!!.
UPDATE: I don't really know if this is important, but it's worth noting that my Windows machine that is rising the error is an Amazon Web Services instance. At my local machine everything's working well!.
UPDATE: Here's some code I ran at the python interpreter of the machine I mentioned. Here you can detail how the error is rising...
>>> from suds.client import Client
>>> from suds.xsd.doctor import ImportDoctor, Import
>>> missing_import = Import("http://www.w3.org/2001/XMLSchema")
>>> missing_import.filter.add("http://tempuri.org/")
>>> doctor = ImportDoctor(missing_import)

raise Exception(msg)
Exception: imported schema (http://www.w3.org/2001/XMLSchema) at (http://www.w3.org/2001/XMLSchema.xsd), failed
UPDATE:
I realized that suds connections always open in TCP increasing ports, and if it reaches the maximum TCP port (65535) then it starts opening again from the minimum TCP port available, so there's no problem with this.
The problem shows up when using suds ImportDoctor, because it has to open a previous connection to the location where the import should be retrieved, and for some reason, if the system reaches the maximum TCP port count, then suds somehow assumes that there's no TCP port available to open the connection for obtaining the import, and in consecuence it throws the exception:
Exception: imported schema (http://www.w3.org/2001/XMLSchema) at (http://www.w3.org/2001/XMLSchema.xsd), failed
I repeat, this only happens if suds has to open this previous connection for obtaining the import. If ImportDoctor is not used, then suds has no problem if the TCP port count reaches its maximum, it just restarts at the minimum port available.
Does anyone has any clue on how to resolve this issue???. I'd really appreciate the help!!!.

I've figured out what the problem was. The schema that was missing from the WSDL I was trying to use with suds was:
http://www.w3.org/2001/XMLSchema
And the XSD file for this schema is at:
http://www.w3.org/2001/XMLSchema.xsd
So when I used suds ImportDoctor to add this schema import, sometimes the w3.org domain was denying my access (don't know why really) and that's why this error was rising:
Exception: imported schema (http://www.w3.org/2001/XMLSchema) at (http://www.w3.org/2001/XMLSchema.xsd), failed
What did I do to solve this problem?. I just downloaded this schema to my machine and used suds ImportDoctor to retrieve this import locally.
And that was it!!!. Confusing bug!!!. But SOLVED.

OpenShift Python mongoDB environment variables not set / can't connect

This is in my application file head:
import os
import sys
from cgi import parse_qs, escape
import pymongo
from pymongo import MongoClient
I have the mongoDB 2.4 gear installed, and am trying to connect via
client = MongoClient('mongodb:$OPENSHIFT_MONGODB_DB_HOST:$OPENSHIFT_MONGODB_DB_PORT/')
I get the errors:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/var/lib/openshift/531b77fd500446980900010d/python/virtenv/lib/python2.7/site-packages/pymongo/mongo_client.py", line 239, in __init__

raise ConfigurationError("Port number must be an integer.")
pymongo.errors.ConfigurationError: Port number must be an integer.
looks like OPENSHIFT_MONGODB_DB_PORT isn't set
print OPENSHIFT_MONGODB_DB_PORT --> NameError: name 'OPENSHIFT_MONGODB_DB_PORT' is not defined
Same with OPENSHIFT_MONGODB_DB_HOST
What would I need to do, to set up a connection?
Update:
I was able to connect directly via client by hardcoding info from rockmongo
client = MongoClient('mongodb://admin:password#[ip addr]:[port]/')
but when I do
client = MongoClient('mongodb:admin:password#%s:%s/' % os.environ['OPENSHIFT_MONGODB_DB_HOST'], os.environ['OPENSHIFT_MONGODB_DB_PORT']))
I get
[error] (<type 'exceptions.KeyError'>, KeyError('OPENSHIFT_MONGODB_DB_HOST',), <traceback object at 0x7f7bc8367248>)

The OpenShift connection variables are defined as environment variables, they cannot be accessed as normal Python variables. So the print statement you gave does not work, the following should;
import os
print os.environ['OPENSHIFT_MONGODB_DB_PORT']
You should change your code to;
client = MongoClient('mongodb:%s:%s/' % (os.environ['OPENSHIFT_MONGODB_DB_HOST'], os.environ['OPENSHIFT_MONGODB_DB_PORT))
You can refer to an example here.

Accessing the Atlassian Crowd SOAP API with Suds (python SOAP library)

Has anybody had any recent success with accessing the Crowd SOAP API via the Suds Python library?
I've found a few people successfully doing it in the past but Atlassian seems to have changed their WSDL since then to make the existing advice not entirely helpful.
Below is the simplest example I've been trying:
from suds.client import Client
url = 'https://crowd.hugeinc.com/services/SecurityServer?wsdl'
client = Client(url)
Unfortunately that generates the following error:
Traceback (most recent call last):
File "<input>", line 1, in <module>
File "/Users/soconnor/.virtualenvs/hugeface/lib/python2.6/site-packages/suds/client.py", line 116, in __init__
sd = ServiceDefinition(self.wsdl, s)
File "/Users/soconnor/.virtualenvs/hugeface/lib/python2.6/site-packages/suds/servicedefinition.py", line 58, in __init__
self.paramtypes()
File "/Users/soconnor/.virtualenvs/hugeface/lib/python2.6/site-packages/suds/servicedefinition.py", line 137, in paramtypes
item = (pd[1], pd[1].resolve())
File "/Users/soconnor/.virtualenvs/hugeface/lib/python2.6/site-packages/suds/xsd/sxbasic.py", line 63, in resolve
raise TypeNotFound(qref)
TypeNotFound: Type not found: '(AuthenticatedToken, http://authentication.integration.crowd.atlassian.com, )'
I've tried to both binding and doctors to fix this problem to no avail. Neither approach resulted in any change. Any further recommendations or suggestions would be incredibly helpful.

There is a patch for the Crowd WSDL here:
