Accessing and Using WS-Management


This chapter describes how to access the SMASH Web Services interface (WS-Management) and provides limited information about its use. For detailed information about using the SMASH WS-Management tool, see the DMTF documentation at this URL:

http://www.dmtf.org/standards/smash

This chapter contains the following topics:

Obtaining and Installing a WS-Management Client

To use WS-Management, you must obtain and install a WS-Management client for your operating system. Free clients are available for common operating systems, including Windows, Macintosh OS X, and Linux.

For this guide, we will use Microsoft Windows Remote Management (WinRM) as an example. WinRM is included with current Windows desktop and server versions, and is available as a download from Microsoft for selected earlier versions. Refer to Microsoft's documentation for instructions on obtaining and installing the appropriate version of WinRM for your client computer.

After installation, WinRM can be run from a Windows command prompt in any directory. To test the installation, enter the winrm id command at the Windows command prompt. The command output should appear as in the following example:

C:\> winrm id
IdentifyResponse
    ProtocolVersion = http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd
    ProductVendor = Microsoft Corporation
    ProductVersion = OS: 5.1.2600 SP: 2.0 Stack: 1.1

Configuring WinRM

By default, WinRM has the following restrictions:

Requires a secure connection (https)

Disallows basic authentication

Trusts no host

You must configure the client to allow unencrypted communication and basic authentication, and to trust certain hosts for unencrypted communication. To make these configuration changes, enter the following commands at the Windows command prompt:

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

This example shows how to verify the configuration:

C:\> winrm get winrm/config/client
Client
    NetworkDelayms = 5000
    URLPrefix = wsman
    AllowUnencrypted = true
    Auth
        Basic = true
        Digest = true
        Kerberos = true
        Negotiate = true
        Certificate = true
    DefaultPorts
        HTTP = 80
        HTTPS = 443
    TrustedHosts = *
C:\>

Viewing the Available Commands

To display the WinRM command options, enter the winrm command at the Windows command prompt, as in the following example:

C:\>winrm
Windows Remote Management Command Line Tool

Windows Remote Management (WinRM) is the Microsoft implementation of
the WS-Management protocol which provides a secure way to communicate
with local and remote computers using web services.

Usage:
  winrm OPERATION RESOURCE_URI [-SWITCH:VALUE [-SWITCH:VALUE] ...]
        [@{KEY=VALUE[;KEY=VALUE]...}]

For help on a specific operation:
  winrm g[et] -?        Retrieving management information.
  winrm s[et] -?        Modifying management information.
  winrm c[reate] -?     Creating new instances of management resources.
  winrm d[elete] -?     Remove an instance of a management resource.
  winrm e[numerate] -?  List all instances of a management resource.
  winrm i[nvoke] -?     Executes a method on a management resource.
  winrm id[entify] -?   Determines if a WS-Management implementation is
                        running on the remote machine.
  winrm quickconfig -?  Configures this machine to accept WS-Management
                        requests from other machines.
  winrm configSDDL -?   Modify an existing security descriptor for a URI.
  winrm helpmsg -?      Displays error message for the error code.

Command Structure

The following example shows a typical winrm get command:

C:\> winrm get 
cimv2/CCIM_IndicatorLED?SystemCreationClassName=CCIM_ComputerSystem+SystemName=srv:1+Creat
ionClassName=CCIM_IndicatorLED+DeviceID=LED_FPID  -r:https://192.0.20.137:443  -a:Basic 
-u:admin -p:password -encoding:utf-8 -f:text  -skipCAcheck -skipCNcheck

The following table describes the fields of this command:

Field
Description
winrm

The main winrm command.

get

This command is a GET CIM Object instance WSMAN operation, which retrieves management information.

cimv2/

The cimv2 path is an alias to the full resource URI that we are trying to retrieve. In this case, it is an alias for a DMTF CIM schema. For more information, enter the winrm help aliases command.

CCIM_IndicatorLED?

This is the object whose properties are being queried.

SystemCreationClassName=CCIM_ComputerSystem

The first of four object identification keys.

+

The + operator links multiple instances of key=value pairs.

SystemName=srv:1

The second of four object identification keys.

CreationClassName=CCIM_IndicatorLED

The third of four object identification keys.

DeviceID=LED_FPID

The last of four object identification keys.

-r:https://192.0.20.137:443

The resource URI. Specifies an HTTP secure connection to the server at the given IP address at port 443. For more information, enter the winrm help remoting command.

-a:Basic

Basic authentication will be used for the server connection. For more information, enter the winrm help auth command.

-u:admin

The username for logging in with basic authentication.

-p:password

The password for logging in with basic authentication.

-encoding:utf-8

Data exchanged with the server will be in UTF-8 enconding. For more information on this field and the remaining fields, enter the winrm help switches command.

-f:text

The format of data exchanged with the server will be formatted as text.

-skipCAcheck

The SSL certificate authority (CA) of the server need not be a trusted root authority.

-skipCNcheck

The SSL common name (CN) of the server need not match the hostname of the server.
