Installation

Install this application into your Python site libraries with:

$ python setup.py install

Dependencies

• Python 2.7
• Twisted 11.0 or later (utilizes HTTP connection pools with Twisted 12.1 or later)

Configuring the Target Windows Machines

You can enable the WinRM service on Windows Server 2003, 2008 and 2012. Run Command Prompt as Administrator and execute the following commands

$ winrm quickconfig
$ winrm s winrm/config/service @{AllowUnencrypted="true";MaxConcurrentOperationsPerUser="4294967295"}
$ winrm s winrm/config/service/auth @{Basic="true"}

WQL Queries

You can pass a single host and query via the command line...

$ winrm -r host -u user -p passwd -f "select * from Win32_NetworkAdapter"

..., or create an ini-style config file and hit multiple targets with multiple queries. Example config is at examples/config.ini

$ winrm -c path/to/config.ini

This will send WinRM enumerate requests to the hosts listed in config.ini. It will send a request for each WQL query listed in that file. The output will look like

<hostname> ==> <WQL query>
    <property-name> = <value>
    ...
    ---- (indicates start of next item)
    <property-name> = <value>
    ...
...

Here is an example...

cupertino ==> Select name,caption,pathName,serviceType,startMode,startName,state From Win32_Service
  Caption = Application Experience
  Name = AeLookupSvc
  PathName = C:\Windows\system32\svchost.exe -k netsvcs
  ServiceType = Share Process
  StartMode = Manual
  StartName = localSystem
  State = Stopped
  ----
  Caption = Application Layer Gateway Service
  Name = ALG
...

A summary of the number of failures if any and number of XML elements processed appears at the end. The summary and any errors are written to stderr, so redirect stdin to /dev/null if you want terse output.

$ winrm -c path/to/config.ini >/dev/null

The '-d' option increases logging, printing out the XML for all requests and responses, along with the HTTP status code.

WinRS

Here is an example of running the Windows typeperf command remotely using the winrs script...

$ winrs -u Administrator -p Z3n0ss -x 'typeperf "\Processor(_Total)\% Processor Time" -sc 1' -r gilroy
{'exit_code': 0,
 'stderr': [],
 'stdout': ['"(PDH-CSV 4.0)","\\\\AMAZONA-Q2R281F\\Processor(_Total)\\% Processor Time"',
            '"04/15/2013 21:26:55.984","0.000000"',
            'Exiting, please wait...',
            'The command completed successfully.']}
