<snip> # nmap -P0 -p80,99,113 scanme.nmap.org As you can see above, Nmap starts by sending a SYN probe back to each of the three ports. Port 113 replies with the RA (RST/ACK) flags and thus is listed by Nmap as closed. Port 80 returns SA (SYN/ACK) and so is listed as open. Port 99 does not reply, so Nmap retransmits after 1.1 seconds. There is still no reply, so Nmap lists the port as filtered. </snip> Hey Fyodor When are you expecting to release with --reason ? <Shamelessly recruiting> We are looking for experienced penetration testers to come and join us.
