Re: faster scans? (nmap)

I'm doing vanilla tcp connect scans (Syns aren't reliable in this case), so I was wondering if any of you have any tips on speeding up the process and not loosing reliablity. Here's the actual syntax nmap -sT -v -n -P0 -p 1- ip.ip.ip.ip-ip.
Try using -PT instead of -P0 to do a tcp-ping of the host before trying to scan it. This should get around the lack of icmp which is why I presume you are using -P0. If icmp is allowed, you could also do a ping scan with -sP. ---------------------------------------------------------------------------- This list is provided by the SecurityFocus Security Intelligence Alert (SIA) Service.
