pywinrm is a Python client for the Windows Remote Management (WinRM) service. It allows you to invoke commands on target Windows machines from any machine that can run Python.
WinRM allows you to perform various management tasks remotely. 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
- requests-kerberos is optional

# for RHEL/CentOS/etc:
$ sudo yum install gcc krb5-devel krb5-workstation

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

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

Enable WinRM over HTTP and HTTPS with self-signed certificate (includes firewall rules):
# from powershell:
Invoke-Expression ((New-Object System.Net.Webclient).DownloadString('https://raw.githubusercontent.com/ansible/ansible/devel/examples/scripts/ConfigureRemotingForAnsible.ps1'))
Enable WinRM over HTTP for test usage (includes firewall rules):
winrm quickconfig
Enable WinRM basic authentication. For domain users, it is necessary to use NTLM or Kerberos authentication (both are enabled by default).
# from cmd:
winrm set winrm/config/service/auth @{Basic="true"}
Allow unencrypted message passing over WinRM (recommended only for troubleshooting and internal use)
# from cmd:
winrm set winrm/config/service @{AllowUnencrypted="true"}
