Well a few things come to mind. 1) Are you running the scan as root? If not it will default to the -sT (TCP Connect()) option. If you are then it defaults ton -sSS (TCP SYN stealth). Running it as a stealth scan would most likely be quicker.
I don't have root privileges :(
I tried them with very slight performance gain. It took 5 mins with -T5. In fact I have given my own timing parameters and brought it down to 4 mins. But there is one more doubt.. there is a huge performance gain if I remove the option -P0. It takes just 1.5 minutes. But it fails to detect around 10% of the ftp servers. Any idea how to tackle this?2) There is the -T flag which you can specify timing. You could try Aggressive or Insane. These would be the flags -T4 or -T5 respectively.
Steven securityzone.orgI am using following command :- nmap -n -P0 -p 21 -oG ftpLog.gnmap -iL IPs.txt Are their other better options? or improvements to above command? It takes around 7 mins to scan a list of 8960 IPs. Its ok, but I am still looking for faster options. -- I do know everything, just not all at once. It's a virtual memory problem.
