Current OS: BackTrack 2 (Figured You'd Need This Info)
Nmap Version: (Tried 4.20 Standard With BackTrack, Now Installed 4.22)
I'm running scans on 50 hosts at a time, scanning the 4th Octet of the ip address. The Command I'm using is provided below:
nmap -p 21,42,445,1433,1434,3389,5900 -P0 -T Insane xxx.xxx.xxx.1-50
My issue is nmap is returning invalid results, its telling me all of the ports are open on each individual machine. Why is this? All help/suggestions are appreciated. Thank you in advanced.
