MediumLevel 1Automatedros

Description

The inetd daemon listens for well known services and dispatches the appropriate daemon to properly respond to service requests. The audit requires openbsd-inetd not to be installed. Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

How it is checked

Audit method: Shell command

shell

command -v dpkg-query >/dev/null 2>&1 || exit 1
bad=0
for p in openbsd-inetd; do
  s=$(dpkg-query -W -f='${Status}' "$p" 2>/dev/null)
  case "$s" in *' installed') echo "$p is installed"; bad=1 ;; esac
done
[ "$bad" -eq 0 ] && echo compliant

Expected output: compliant

How it is fixed
