Hi guys,

I explained myself in a bad way,I try to more precise here ;

I know a bit Idle scan but I still have to find a good zombie,meanwhile I
did that :

I firstly issued a simple scan like that :
nmap -vv -P0 -T4 -sS xxx.xxx.xxx.50

and I obtained 2 open ports, 21 and 23

then I tried to spoof my ip scanning the same target like that :
nmap -vv -P0 -T4 -S xxx.xxx.xxx.xxx ( spoofed ) -e eth0 xxx.xxx.xxx.50 (
same target as simple scan ) but I obtained every port closed even if nmap
scanned clearly the same target as the original trivial scan against
xxx.xxx.xxx.50.

Am I badly synthaxing ?..or anything alse that I am missing ?

Thanks guys

Yashin

P.S. : beeing new here I still have to understand how to proprerly reply to
messages :-( , thanks Tim about helping me :-)
