| What nmap does different when scanning "own machine ip address" to when
it scans remote machines.??? or it uses the same algo???
I feel nmap must be doing something different when scanning own
machine(eth 0) as i myself have wrritten the port scanner which scans
remote machines well but not the machine on which it is running.
I tried to look at nmap code but it is difficult to understand what's
happening there

I'd suggest taking this question to either an nmap group (it's possible
that there aren't any on the Usenet but that you will have to use
mailinglists or forums).

Just a guess, are you aware that 'localhost' and 'your-hostname' are
different like e.g. '127.0.0.1' and '182.168.0.42'? Maybe the difference
is simply that.

They might appreciate some help refactoring code for readability, just ask
them...

Ya I know there is a difference , I'm talking about '182.168.0.42'.
