Hello!

While running nmap against a host on my internal network today, I specified a pair of mutually incompatible options 
by mistake.  nmap displayed an error message and terminated without running the scan, as it should, but the error 
message returned didn't quite match the problem:

$ sudo nmap -sP -v -v -v -p1-1024 192.168.3.62

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2006-10-11 09:36 AKDT
No ports specified -- If you really don't want to scan any ports use ping scan...
QUITTING!
$

As you can see, I *was* using a ping scan, and I *did* specify ports.  Of course, that was the problem--you shouldn't 
specify ports when running a ping scan.  Not a big problem, but I thought I would point it out, in case you'd like to 
fix it.

Here is the relevant system information regarding the host from which I was running the scan:

$ uname -a
Linux 2.6.17-gentoo-r8 #1 SMP PREEMPT Wed Sep 20 15:51:03 AKDT 2006 i686 Genuine Intel(R) CPU           T2600  @ 
2.16GHz GNU/Linux
$ sudo nmap -V

Nmap version 4.11 ( http://www.insecure.org/nmap/ )
$

I experience the same issue in Slackware 11.0 using nmap-4.11
