Ensure dhcp server services are not in use

SrednjaNivo 1Automatskaaix

Opis

The dhcpsd deamon is the DHCP server that serves addresses and configuration information to DHCP clients in the network. Unless a system is specifically set up to act as a DHCP server, it is recommended that the dhcpd fileset be removed to reduce the potential attack surface. Audit: the dhcpsd start line in /etc/rc.tcpip must be commented out and the dhcpsd subsystem must not be active.
