Hi Cory,

On Sun, Jan 25, 2009 at 08:49:14PM -0500 or thereabouts, Cory K. Walker wrote:
I was hoping someone would comment on the usefulness of a more
general method to specify a list of hosts in an external file for decoys,
DNS servers, etc..

I'm not against such a feature especially if it results in more
uniform command line behaviour. I just want to point out how I
would do this:

nmap --dns-servers `cat servers.txt|perl -ne 's/\s+/,/g;print'` -sL microsoft.com/24

where servers.txt holds a list of IPs separated by newlines,
spaces, tabs, or commas so it will accept -iL files.

Also note that by leaving off --dns-servers it will use a
file by default: /etc/resolv.conf (or, on windows, the
registry). This format is different than the format used
by -iL.

Hope this helps,

Doug
