Ensure xinetd services are not in use

MediumLevel 1Automatedlinux

Description

The eXtended InterNET Daemon (xinetd) is an open source super daemon that replaced the original inetd daemon. The xinetd daemon listens for well known services and dispatches the appropriate daemon to properly respond to service requests.

How it is checked

Audit method: Shell command

shell

alt0() { command -v rpm >/dev/null 2>&1 || { echo "step1: rpm not installed"; return 1; }; o=$(bash -c 'rpm -q xinetd' 2>&1); printf '%s\n' "$o" | tr -s ' \t' '  ' | sed 's/^ //;s/ $//' | grep -Fxq -- 'package xinetd is not installed' || { echo step1: missing 'package xinetd is not installed'; return 1; }; }; alt1() { command -v grep >/dev/null 2>&1 || { echo "step1: grep not installed"; return 1; }; command -v systemctl >/dev/null 2>&1 || { echo "step1: systemctl not installed"; return 1; }; o=$(bash -c 'systemctl is-enabled xinetd.service 2>/dev/null | grep '"'"'enabled'"'"'' 2>/dev/null); [ -z "$o" ] || { echo "step1: $o" | head -c 300; return 1; }; command -v grep >/dev/null 2>&1 || { echo "step2: grep not installed"; return 1; }; command -v systemctl >/dev/null 2>&1 || { echo "step2: systemctl not installed"; return 1; }; o=$(bash -c 'systemctl is-active xinetd.service 2>/dev/null | grep '"'"'^active'"'"'' 2>/dev/null); [ -z "$o" ] || { echo "step2: $o" | head -c 300; return 1; }; }; if alt0 || alt1; then echo compliant; fi

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following commands to stop xinetd.service, and remove the xinetd package: # systemctl stop xinetd.service # dnf remove xinetd - OR - - IF - the xinetd package is required as a dependency: Run the following commands to stop and mask the xinetd.service: # systemctl stop xinetd.service # systemctl mask xinetd.service
