1.4 ESXI-80-000010

Information

The ESXi host client must be configured with an idle session timeout.

GROUP ID: V-258731
RULE ID: SV-258731r958402

The ESXi host client is the UI served up by the host itself, outside of vCenter. It is accessed at https://<ESX FQDN>/ui. ESXi is not usually administered via this interface for long periods, and all users will be highly privileged. Implementing a mandatory session idle limit will ensure that orphaned, forgotten, or ignored sessions will be closed promptly.

Solution

From the vSphere Client, go to Hosts and Clusters.

Select the ESXi Host >> Configure >> System >> Advanced System Settings.

Click "Edit". Select the "UserVars.HostClientSessionTimeout" value and configure it to "900".

or

From a PowerCLI command prompt while connected to the ESXi host, run the following command:

Get-VMHost | Get-AdvancedSetting -Name UserVars.HostClientSessionTimeout | Set-AdvancedSetting -Value "900"
