Description
When the ESXi Shell or Secure Shell (SSH) services are enabled on a host, they will run indefinitely. To avoid having these services left running, set the "ESXiShellTimeOut". The "ESXiShellTimeOut" defines a window of time after which the ESXi Shell and SSH services will be stopped automatically.
ℹ️ Check
From the vSphere Client, go to Hosts and Clusters. Select the ESXi Host >> Configure >> System >> Advanced System Settings. Select the "UserVars.ESXiShellTimeOut" value and verify it is set to less than "600" and not "0". or From a PowerCLI command prompt while connected to the ESXi host, run the following command: Get-VMHost | Get-AdvancedSetting -Name UserVars.ESXiShellTimeOut If the "UserVars.ESXiShellTimeOut" setting is set to a value greater than "600" or "0", this is a finding.
✔️ Fix
