pywinrm is a Python client for Windows Remote Management (WinRM). This allows you to invoke commands on target Windows machines from any machine that can run Python.

WinRM allows you to call native objects in Windows. These include, but are not limited to, running batch scripts, powershell scripts and fetching WMI variables. For more information on WinRM, please visit Microsoft's WinRM site.

• Linux, Mac OS X or Windows
• CPython 2.6-2.7, 3.2-3.5 or PyPy 1.9
• python-kerberos is optional

$ pip install pywinrm

$ sudo apt-get install python-dev libkrb5-dev
$ pip install kerberos

import winrm

s = winrm.Session('windows-host.example.com', auth=('john.smith', 'secret'))
r = s.run_cmd('ipconfig', ['/all'])
>>> r.status_code
0
>>> r.std_out
Windows IP Configuration

   Host Name . . . . . . . . . . . . : WINDOWS-HOST
   Primary Dns Suffix  . . . . . . . :
   Node Type . . . . . . . . . . . . : Hybrid
   IP Routing Enabled. . . . . . . . : No
   WINS Proxy Enabled. . . . . . . . : No
...
>>> r.std_err

NOTE: pywinrm will try and guess the correct endpoint url from the following formats:

• windows-host -> http://windows-host:5985/wsman
• windows-host:1111 -> http://windows-host:1111/wsman
• http://windows-host -> http://windows-host:5985/wsman
• http://windows-host:1111 -> http://windows-host:1111/wsman
• http://windows-host:1111/wsman -> http://windows-host:1111/wsman

import winrm

ps_script = """$strComputer = $Host
Clear
$RAM = WmiObject Win32_ComputerSystem
$MB = 1048576

"Installed Memory: " + [int]($RAM.TotalPhysicalMemory /$MB) + " MB" """

s = winrm.Session('windows-host.example.com', auth=('john.smith', 'secret'))
r = s.run_ps(ps_script)
>>> r.status_code
0
>>> r.std_out
Installed Memory: 3840 MB

>>> r.std_err

Powershell script will be base64 UTF16 little endian encoded prior to sending to Windows host. Error messages are converted from the Powershell CLIXML format to a human readable format as a convenience.

from winrm.protocol import Protocol

p = Protocol(
    endpoint='http://windows-host:5985/wsman',
    transport='plaintext',
    username='john.smith',
    password='secret')
shell_id = p.open_shell()
command_id = p.run_command(shell_id, 'ipconfig', ['/all'])
std_out, std_err, status_code = p.get_command_output(shell_id, command_id)
p.cleanup_command(shell_id, command_id)
p.close_shell(shell_id)

• Enable basic WinRM authentication (Good only for troubleshooting. For hosts in a domain it is better to use Kerberos authentication.)
• Allow unencrypted message passing over WinRM (not secure for hosts in a domain but this feature was not yet implemented.)

winrm set winrm/config/client/auth @{Basic="true"}
winrm set winrm/config/service/auth @{Basic="true"}
winrm set winrm/config/service @{AllowUnencrypted="true"}
