Now that nmap has the ability to log MAC addresses does it use the fact
that it got an arp reply to establish that the host is in fact up, my
idea here basically is that an ARP reply is basically the only sure way
to determine if a host is up or not, if you don't get one, then that
host must be down, if you do in 99.99% of cases it is up (feel free to
correct me), so does, or should nmap use a positive ARP reply to say
that the host is up?
On top of that, ARP replies are also much faster than scanning all
ports on closed hosts (-P0).
Adam
Where is it written in the Constitution, in what article or section is
it contained, that you may take children from their parents and parents
from their children, and compel them to fight the battles of any war in
which the folly and wickedness of the government may engage itself?
Under what concealment has this power lain hidden, which now for the
first time comes forth, with a tremendous and baleful aspect, to
trample down and destroy the dearest right of personal liberty? Who
will show me any Constitutional injunction which makes it the duty of
the American people to surrender everything valuable in life, and even
life, itself, whenever the purposes of an ambitious and mischievous
government may require it? . . . A free government with an uncontrolled
power of military conscription is the most ridiculous and abominable
contradiction and nonsense that ever entered into the heads of men.
-Daniel Webster
