Ne drzi.

iz man nmap:

The result of running nmap is usually a list of  interesting  ports  on  the  
machine(s) being  scanned  (if  any).   Nmap  always gives the port's "well 
known" service name (if any), number, state, and protocol.  The state is 
either "open", "filtered",  or  "unfiltered".   Open  means  that  the target 
machine will accept() connections on that port. Filtered means that a 
firewall, filter, or other network obstacle is covering  the  port and 
preventing  nmap  from determining whether the port is open.  Unfiltered 
means that the port is known by nmap to be closed and no firewall/filter 
seems  to  be  interfering with  nmap's  attempts  to determine this.  
Unfiltered ports are the common case and are only shown when most of the 
scanned ports are in the filtered state.

To vse je bilo v tem threadu ze povedano, ceprav ne s citatom iz man page-a.

Kar pa me privede do necesa drugega. Zanima me, zakaj morajo ljudje nekaj 
pripomnit (po moznosti napacen odgovor, ali pa povsem nekoristnega), ceprav 
je bilo na zadevo ze PRAVILNO odgovorjeno 12 ur prej, poleg vsega pa je 
odgovor ociten tudi iz man pagea? Jaz osebno na tej mailing listi zelo zelo 
pogresam odgovore v stilu RTFM, kadar so vprasanja tako preprosta, kot je 
bilo v tem threadu. Mogoce bi ljudi (spet) morali nauciti porabiti par minut 
svojega casa, preden posljejo preprosto vprasanje in ukradejo (skupno) vec 
casa tistim, ki to listo beremo.

To bo v bodoce moj modus operandi na tej listi, v primerih ko se ljudje ne 
bojo niti minimalno potrudili, da bi poiskali odgovor na svoje vprasanje 
najprej kje drugje (vsaj google, man). RTFM,M (RTFM, moron).

Podpiranje lenobe ne pelje nikamor. Tistim, ki so leni, je treba porabljeni 
cas zaracunat.

lp,
Borut.
