Hi all,
       I faced a problem running two tools producing totally different results.
What i did is described as ...I ran nmap on a IP with these parameters
: syn scan,dont ping,very verbose ,aggressive scan..it showed ports 80
n 1723 filtered.I ran this scan from Linux box.
Same time ,i used netwag to scansame ip which showed these ports open.

What can be the problem..??please help.

Run tcpdump and see what the packets going out and coming back
are. You can soon see which is reporting correctly. FWIW, my money is
on nmap being correct. Have a look at the nmap manpage to see what it
terms 'filtered'.

PS. You may want to change your handle. Someone else called "Aleph
One" used to moderate bugtraq, amongst other things, and people will
get confused.
