Mate trochu stary nmap, ne?

Ac tvrdite, ze "firewallovacima pravidlama by to byt nemelo", tak nmap na
nejake filtry nejspis narazil (srazka s filtrem je typicke vysvetleni
toho, kdyz send() resp. sendto() vrati na Linuxu EPERM).

Zajimave: tohle trvalo 19 sekund, zatimco localhost jen 0 sekund.
U 192.168.1.1 ten udaj bohuzel chybi. Ovsem ten velky rozdil naznacuje,
ze by v tom mohl mit prsty nejaky filtr.

Rozhodne bych doporucil zkusit otevrit normalni spojeni (napr. netcatem,
telnetem nebo normalnim klientem pro danou sluzbu) a odposlechnout, co se
na te siti deje (nastroju je spousta: tcpdump, ethereal atd.).
