Host must automatically terminate idle DCUI sessions

How it is checked

Audit method: Shell command

out=$(esxcli system settings advanced list -o /UserVars/DcuiTimeOut 2>/dev/null) || exit 1
v=$(printf '%s\n' "$out" | awk '$1=="Int" && $2=="Value:" {print $3; exit}')
case "$v" in ''|*[!0-9-]*) echo '/UserVars/DcuiTimeOut: no integer value'; exit 1 ;; esac
if [ "$v" -gt 0 ] && [ "$v" -le 600 ]; then echo compliant; else echo "/UserVars/DcuiTimeOut = $v (expected 1-600)"; fi

Expected output

compliant

How it is fixed

Fix method: Guidance or infrastructure patch

To correct the DCUI timeout setting, perform the following steps: 1. From the vSphere Web Client, select the host. 2. Click Configure, then under System select Advanced System Settings. 3. Select Edit then enter UserVars.DcuiTimeOut in the filter. 4. Click in the box for the current value, then set the value to 600 seconds or less. Alternately, use the following PowerCLI command: Get-VMHost | Get-AdvancedSetting -Name UserVars.DcuiTimeOut | Set-AdvancedSetting -Value 600
