RFE: Pseudo target for local network(s)

[Thomas Henlich <thenlich () users sourceforge net>]

Hi,

it would be neat to have an option to tell nmap to scan all hosts on the
local net on a specified network interface, or on all active network
interfaces (excluding loopback), without having to specify the
addresses/masks myself (e.g. on mobile machines).

I propose a pseudo target (e. g. "*") for this. For example:

On a machine with two interfaces
eth0: 192.168.1.0/24 broadcast 192.168.1.255
eth1: 10.1.2.0/24 broadcast 10.1.2.255

the following commands should have these equivalents:
nmap -e eth0 * -> nmap -e eth0 192.168.1.0-254
nmap -e eth1 * -> nmap -e eth1 10.1.2.0-254
nmap * -> nmap 192.168.1.0-254 10.1.2.0-254

Regards,
 Thomas.
