Hi, in its Auditing Report tiger throws this message: # Performing check of services with tcp wrappers... --FAIL-- [inet021f] Tcp wrappers does not seem to be installed in this system. As far as I understand the script /usr/lib/tiger/scripts/check_tcpd checks for the system variable $TCPD for the tcpd path. But $TCPD seems to be empty on Debian Buster. Means I couldn't find it with "echo $TCPD" or by "env | grep -i tcpd" as root. tcp wrappers are installed and actively used and working on this system. Kind regards Steffen
