Hi! I'm compiled a Kernel using the GENERIC config-file that comes with the default 5.2.1 installation adding support for ipfw. I tried to scan my computer with a linux machine running nmap, but nmap tells me that the host seems to be down altough I was able to ping the freebsd-host. So I flushed all rools for the firewall with ipfw flush (the still existing default rule enables all trafic because I compiled this in my kernel, ipfw -c list told me that this is true.) Anyway, nothing changes, all ports seem to be closed running nmap, pings are successfull again! 1) What's wrong with my configuration? 2) I've tried to add all kernel options to this mail using the online handbook from www.freeebsd.org. I realized that the firewall section covers now the OpenBSD filter pf. What=B4s the state of the art? How do I enable pf under 5.2.1 - package or port? 3) Is there something similar like nmap or is there a BSD-network scanner, which usage is recommended? Thanks in advance, Florian ------------------------------------------------------ Florian Hengstberger e0025265@student.tuwien.ac.at http://stud3.tuwien.ac.at/~e0025265 ------------------------------------------------------
