-sT (SYN helyett OS nativ connect() hivas hasznalata) segit valamelyest, bar warning ekkor is erkezik:


 $ sudo nmap -sT -e fxp0 -p 1-12345 -PN 333.33.333.10

Strange error from connect (65):No route to host
Interesting ports on 333.33.333.10:
Not shown: 12344 filtered ports
PORT   STATE SERVICE
80/tcp open  http

Nmap done: 1 IP address (1 host up) scanned in 31.06 seconds

Sajnos ez az nmap verzio mar kicsit elavult (5.21 a jelenlegi stabil kiadas), tehat eleve itt kellene kezdeni a problemakeresest.
