Virtual machines must limit console sharing.

SedangLevel 1Otomatisvmware

Deskripsi

By default, remote console sessions can be connected to by more than one user at a time. Permit only one remote console connection to a VM at a time. Other attempts will be rejected until the first connection disconnects. Expected: RemoteDisplay.maxConnections = "1". The audit parses every .vmx file under /vmfs/volumes/ on the host and lists the VMs that do not comply; it passes when none are found (or no VMs exist). Runs in the ESXi Shell (busybox sh) as root.

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

To set this configuration utilize the vSphere interface as follows: 1. Select the VM then select Actions followed by Edit Settings. 2. Click on the VM Options tab then expand Advanced. 3. Click on EDIT CONFIGURATION. 4. Click on ADD CONFIGURATION PARAMS then input RemoteDisplay.maxConnections with a value of 1. 5. Click OK, then OK again. Alternatively, run the following PowerCLI command for VMs that do not specify the setting: # Add the setting to all VMs Get-VM | New-AdvancedSetting -Name "RemoteDisplay.maxConnections" -value 1 Run the following PowerCLI command for VMs that specify the setting but have the wrong value for it: # Add the setting to all VMs Get-VM | New-AdvancedSetting ...
