Python library for Windows Remote Management

Project description

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.

Requirements

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

Installation

To install pywinrm with support for basic, certificate, and NTLM auth, simply

$ pip install pywinrm

To use Kerberos authentication you need these optional dependencies

# for Debian/Ubuntu/etc:
$ sudo apt-get install python-dev libkrb5-dev
$ pip install pywinrm[kerberos]

# for RHEL/CentOS/etc:
$ sudo yum install gcc krb5-devel krb5-workstation
$ pip install pywinrm[kerberos]

Example Usage

Run a process on a remote host

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:

Run Powershell script on remote host

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 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.

Run process with low-level API with domain user, disabling HTTPS cert validation

from winrm.protocol import Protocol

p = Protocol(
    endpoint='https://windows-host:5986/wsman',
    transport='ntlm',
    username=r'somedomain\someuser',
    password='secret',
    server_cert_validation='ignore')
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)

Enabling WinRM on remote host

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"}
