Change vSphere PowerCLI proxy settings

January 24, 2011 — 5 Comments

Today I was performing a test in the vSphere cluster I have in my laptop and when I tried to connect to the vCenter Server with PowerCLI I got the following error.

[vSphere PowerCLI] % get-vc vcenter.mlab.local -user Administrator -Password vmwarerules!
Connect-VIServer : 24/01/2011 12:58:33    Connect-VIServer        Could not connect using the requested protocol.

[vSphere PowerCLI] %

My first thought after that was to check network connectivity and the firewall configuration of the vCenter Server but everything was OK. Then after a quick search in the VMware Communities I found the solution in this post.

The problem was the proxy server configuration of PowerCLI, I’m used to do everything directly from the vCenter desktop, where I have installed PowerCLI and the vSphere Client, but this time I tried to connect directly from my laptop and since I was connected to the corporate network PowerCLI was trying to connect through the proxy server. Following is how I fixed this thanks to the above VMTN post.

First retrieve the PowerCLI proxy configuration with the Get-PowerCLIConfiguration cmdlet.

[vSphere PowerCLI] % Get-PowerCLIConfiguration

Proxy Policy    Default Server
------------    ---------------
UseSystemProxy  Multiple       

[vSphere PowerCLI] %

As you can see Proxy Policy is set to UseSystemProxy. To set this value to NoProxy use the cmdlet Set-PowerCLIConfiguration.

[vSphere PowerCLI] % Set-PowerCLIConfiguration -ProxyPolicy NoProxy

Perform operation?
Performing operation 'Update vSphere PowerCLI configuration.'?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "Y"): y

Proxy Policy    Default Server
------------    ---------------
NoProxy         Multiple       

[vSphere PowerCLI] %

Now try to reconnect to the vCenter Server and everything should go without errors.

[vSphere PowerCLI] % get-vc vcenter.mlab.local -user Administrator -Password vmwarerules!
