On a 4.5-RELEASE firewall ports 1021 1022 1023 are shown open by /usr/ports/security/portscanner, but not listed in /etc/services. Are they daemons doing auto decrement allocation from 1024 ? ( I'm using ipfw firewall, not using diverts (yet), not using X server, am using various other daemons inc. nfs amd lpd timed whod etc) Should I block some 1023 port range with ipfw on non {localhost & local ethernet} interfaces ? What range ? submission=587 is also open. Could someone please remind me the name of a command to back trace the port to whatever's opened it ? Would it be a good idea to add a commented hint at entry 1023 of /etc/services ?
