WSMAN enables you to access information about the server and change it remotely and securely. Client systems communicate with Servers to obtain this data. Both Windows and Linux clients could be used. The question we often stumble upon is how to set up and configure client machines for establishing such communication. The following steps are required for successful Windows client (WinRM) setup:
Install & Configure WinRM
Step 1: Determining WinRM version:
- Windows must be running WinRM version 2.0. This is native to Windows 7 and Windows Server 2008 R2.
- You can determine the winrm version installed on your system by running: winrm id
- The Version number is shown in the command output after "Stack:"
- If you do not have version 2.0, follow the instructions in the article below.
For more information about how to install WinRM 2.0 as a part of the Windows Management Framework Core package, see article 968929 in the Microsoft® Knowledge Base.
- Run the following in a cmd window as administrator:
winrm quickconfig (it will indicate if already setup, otherwise select "y" each time as prompted)
Step 2: Configuring WinRM settings:
Run the following: winrm get winrm/config
And make sure the following settings are returned:
MaxEnvelopeSizekb = 150
MaxTimeoutms = 60000
MaxBatchItems = 50
NetworkDelayms = 60000
Basic = true (this is Under Client > Auth)
Leave all other settings at their default values. If you need to change any of the above use the corresponding commands below:
winrm set winrm/config @{MaxEnvelopeSizekb="150"}
winrm set winrm/config @{MaxTimeoutms="60000"}
winrm set winrm/config @{MaxBatchItems="50"}
winrm set winrm/config/client @{NetworkDelayms="60000"}
winrm set winrm/config/Client/Auth @{Basic="true"}
Step 3: Check Functionality
Run the following command to verify basic winrm functionality:
winrm e cimv2/root/dcim/DCIM_ComputerSystem -u:root -p:calvin -r:https://10.210.112.54/wsman -SkipCNcheck -SkipCAcheck -encoding:utf-8 -a:basic
*Substitute the IP shown above with the IP address of your iDRAC.
