maybe old stuff, just happened to me and can't find something in the docs
or elsewhere. When dong the -sP with an ASA in between you and the target,
the tcp-syn on port 80 will be answered by a RST from the ASA, thereby making
nmap think the host is responding and alive. Of course the results of such
a scan are basically useless then.
Would it be possible to ignore RST in such a szenario? Or have a command
line switch to trigger this?
That can be a problem with port 80. You may want to try a different
type of ping scan (such as ICMP only) or change the TCP ping probe
Ok, my error, seems like I do write a very stupid mail every few years, this
has been it for this period :( Could have seen in the manpage that the -PE
disables the syn on port 80.
