Protocol specific port lists - setting TCP ports removes UDP default list

[Marcus Haebler <haebler () gmail com>]

Hi,

I am trying to figure out if the following behavior is a bug or a feature:

nmap -vvv -n -r -sS -sU -p T:1-100 <target>

This will scan TCP ports 1-100 but no UDP ports. The UDP port list is empty
and consequently no scan is done. I would have expected that the UDP port
list is still the default list of ports.

The documentation does not mention this behavior. If it turns out to be the
desired behavior it should be added to the documentation.

BTW what I really want to do is scan the top 1000 UDP ports and all 64k TCP
ports in one scan. This seems to be impossible in a single scan at this
point since --top-ports seems to take precedence over everything specified
with -p.

# nmap -V
Nmap version 5.35DC1 ( http://nmap.org )


Thanks,

Marcus
