Think of that file as an ASCII database file which applications can access for converting name/port/datatype to other values. Contents in those files are registered by different vendors at http://www.iana.org for their apps. Two examples from my firewall rules. ACCEPT net:$CHRIS_IP all tcp ssh REJECT net:$LAN_GATEWAY all udp netbios-ns That way I do not have to lookup the actual port number.
