wide-scan?

[Bradley Kite <bradley () deathsgate demon co uk>]

Hi everybody.

I'm considering adding a 'wide-scan' option to nmap,
so that instead of scanning all ports on each host,
then moving to the next host (a deep scan) it will
scan port 1 on all hosts, and then move to port 2
(well it will actually move through the user-supplied
port list but you get my meaning...)

I think that it will provide increased paralellism(?)
when scanning a lot of hosts with paranoid (-T) timing options
because while you are waiting, you can scan other hosts.

The down side is that it will require a lot more memory,
but you can get around this by reducing the number of ports
you want to scan.

Comments/Suggestions requested.
