Strange NMAP 4.0 Behavior

Derek, The default scan when not specified is -sS -F. If you only wanted to do an ICMP Echo Ping Scan and no more, use -sP -PE. So while there is no bug, I looked over the man pages and nmap's defaults are not explicitly detailed in any section. For the novice, it is not clear what actions the command "nmap scanme.insecure.org" will invoke. Maybe we (the nmap community) can work on documenting that better, especially with the recent additions of things like nmap's own ARP stack, and DNS resolution. Thanks for the feedback. kx On 2/20/06, Derek Nash <ddnash () gmail com> wrote:
I was just noticing when running an ICMP Echo scan (-PE) in NMAP version 4.00 that it seems to be including a SYN scan on all Service ports (-sS -F) scan as part of this scan type. I have witnessed this on 2 separate installs and systems, I couldn't find documentation that states this is a new default behavior. Has anyone else witnessed this strange behavior? If this is a new default behavior does anyone know if this behavior is defeatable? This seems like a bug to me, but I thought I would post here prior to submitting a bug report.
