PyControl driving me round the bend!!

All,

Disclaimer first - I am an iControl n00b. Total hours messing with iControl is ~8.

Status: ran through the pyControl setup doc but did the Mac OSX equivalents to get it up and running.

Tried to use the sample apps, which have run once or twice, but refuse now to run, with no change that I am aware of having taken place between the run that worked, and the run that did not. obviously I have modified the section of the system_quick_audit.py script to make sure my bigip's IP/username/password combo is set.

Current status:

    Based the exception being thrown, looks like the path/file changed or something related that caused the script to not be able to find the wsdl.

    hmm.. is there a way to instruct pyControl to ignore it's cache? I assume the WSDL is exposed on the BigIP? (showing my ignorance here I am sure...)

    Odd. It may be worth poking around a bit more to see if there's not a path issue. Could you print out your sys.path and compare it to your WSDL_CACHE dir?

    Here's an example: 

     
  In: import sys   
  In: sys.path   
  Out:   
   ['',   
    '/usr/bin',   
    '/usr/lib/python2.5/site-packages/setuptools-0.6c9-py2.5.egg',   
    '/usr/lib/python2.5/site-packages/ipython-0.9.1-py2.5.egg',   
    '/usr/lib/python2.5/site-packages/MySQL_python-1.2.2-py2.5-linux-i686.egg',   
    '/usr/lib/python2.5/site-packages/pyControl-1.3.0_beta-py2.5.egg',   
    '/usr/lib/python2.5/site-packages/ZSI-2.1_a1-py2.5.egg',   
    '/usr/lib/python25.zip',   
    '/usr/lib/python2.5',   
    '/usr/lib/python2.5/plat-linux2',   
    '/usr/lib/python2.5/lib-tk',   
    '/usr/lib/python2.5/lib-dynload',   
    '/usr/local/lib/python2.5/site-packages',   
    '/usr/lib/python2.5/site-packages',   
    '/var/lib/python-support/python2.5',   
    '/usr/lib/python2.5/site-packages/ipython-0.9.1-py2.5.egg/IPython/Extensions']   
      
   In: import pycontrol.pyControl as pc   
    
   In: pc.WSDL_CACHE   
   Out: '/usr/lib/python2.5/site-packages/pyControl-1.3.0_beta-py2.5.egg/pycontrol/BIGIP_WSDL_CACHE_DIR/wsdl'

    The WSDL_CACHE attribute should point to the pyControl egg file. This should help you identify what is going on. On my debian system I had fits with path issues across multiple apt-installed python versions, so keep an eye out for something like this as well.

    By the way, this points out a bug that I'll need to fix, and this is a variant of another issue posted to the forums regarding needing elevated perms to write to this directory. It would be nice to be able to set this all up and point it at a $TMP directory on a particular system.

    It should be possible to manually set this attribute but it's not behaving the way I expect when I do this. I'll try and fix this up and submit a new (and overdue) pyControl egg.

    Upon a closer look, it appears that you may have a typo in the demo script. From a python command prompt, try and simply load the WSDL: 

       
   In: b = pc.BIGIP(hostname = '192.168.1.245', username='admin', password='admin', wsdl_files = ['System.SystemInfo'])   
      
   Loading WSDL: System.SystemInfo.wsdl   
      
   In: b.System_SystemInfo.get_version()   
   Out: {'return': 'BIG-IP_v9.4.5'}

    HTH,
