Citrix NetScaler, the industry's most popular load balancer, can also be configured to use SMS authentication, with Citrix Receiver, XenApp and XenDesktop.
Citrix partner SMS passcode makes the SMS software, it is easy to install and easy to use. The Citrix Reciever already supports SMS Authentication.

In previous posts Citrix has shown how Authentication can be done at the Citrix Server Web Interface, or using LDAP. Now that Citrix Receiver runs on a variety of mobile devices, you can use SMS Authentication and Receiver on your device of choice.

Citrix has used the previous infrastructure for this Proof Of Concept, because it was already setup with XenApp and XenDesktop. The only new piece was the SMS Passcode server.

Citrix has a ton of documentation for Perl/C/C# and Java ( None for Python ). SOAP client support has not been the best for Python, but is getting better.
If you have soappy/ZSI, which have had issues with regards to consuming Broken WSDL files ( Having to fix the Broken WSDL file manually, SUCKS!).

Enter SUDS. This module is by far, the best SOAP client for Python.
There documentation is simple and straight to the point, with a bunch of nice samples to get you on your way.

Install SUDS before proceeding further. You can get suds from here. https://fedorahosted.org/suds/

Connection to my netscaler was as simple as this...

Python 2.4.3 (#1, Sep  3 2009, 15:37:37)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-46)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from suds.client import Client
>>> url = "http://nsip/api/NSConfig.wsdl"
>>> from suds.xsd.doctor import *
>>> imp = Import('http://schemas.xmlsoap.org/soap/encoding/')
>>> imp.filter.add("urn:NSConfig")
>>> d = ImportDoctor(imp)
>>> client = Client(url, doctor=d, location="http://nsip/soap/")
>>> client.service.login(username="login", password="pass")
(simpleResult){
 rc = 0
 message = "Done"
 }
>>>

As you can see above,  here we used the xsd doctor to import Soap encoding URL and added a filter for the Netscaler URN.
If you do not import the SOAP encoding schema, this is the error you will receive..

suds.TypeNotFound: Type not found: '(Array, http://schemas.xmlsoap.org/soap/encoding/, )

Once you type the above, you can now run commands in the python shell. for instance...

• client.service.getlbvserver()
• client.service.getservice()
• client.service.getservicegroup()

I am attaching a script that I have written, to get Load Balanced Virtual Servers and its Services and ServiceGroups.
This script can also just list all the Virtual Servers, Services, or Service Groups. Examples below..

python queryns.py -c "ZenossTest2_svc" -n "nsip" -u "login" -p "pass"

Service Name              Server Name         Status               IPAddress              Port       Protocol  
ZenossTest2_svc           zenossTest          OUT OF SERVICE       192.168.101.221        9090       HTTP

python queryns.py -s foobar_test -n "nsip" -u "login" -p "pass"

Virtual Server            State      IPAddress              Port       Protocol  
foobar_test               UP         192.168.101.19         55555      HTTP

"Foo Bar"                 ENABLED              billyboy             UP         192.168.101.31      8080       HTTP      
"Foo Bar"                 ENABLED              zenossTest           UP         192.168.101.221     8080       HTTP      

Service Name              Server Name          Status               IPAddress            Port       Protocol  
ZenossTest2_svc           zenossTest           OUT OF SERVICE       192.168.101.221        9090       HTTP
