Configuring a Windows host
Configures a Windows host to allow ViPR to run commands on it.
Before you begin
u
You must be logged in to the Windows host as administrator.
u
For the ViPR server to connect to Windows remote hosts, the host must accept remote
Windows PowerShell commands. You can do this by enabling Windows remote
access over HTTP.
Procedure
1. At an administrator command prompt on the Windows host, issue the following
command:
winrm quickconfig
This starts up a listener on port 5985. The port on which you start the listener must be
consistent with the port that you configure for the host in the host asset page.
2. You may need to make some configuration changes depending on how you want to
connect to the host.
l
If you want ViPR to connect to the host as a local user, you need to:
a. Check the winrm settings by running:
winrm get winrm/config/service
Basic Authentication and AllowUnencrypted must be set to true.
b. If basic authentication is not set to true, run:
winrm set winrm/config/service/auth @{Basic="true"}
c. If AllowUnencrypted is not set to true, run:
winrm set winrm/config/service @{AllowUnencrypted="true"}
d. The host must be added to the Admin > Physical Assets > Hosts page.
l
If you want ViPR to connect to the host as a domain user, you need to:
a. Ensure Kerberos is enabled. You can check using:
winrm get winrm/config/service
b. If you need to enable Kerberos, run:
winrm set winrm/config/service/auth @{Kerberos="true"}
c. Ensure that your domain has been configured as an authentication provider in
ViPR by a System Administrator (Admin > Security > Authentication Providers).
