=head1 NAME
flood - perform a DoS attack
=head1 SYNOPSIS
Flood the target computer with packets.
B<flood> [ B<-d> I<seconds> ] [ B<-s> I<bytes> ] [ B<-t> I<threads> ] I<address>
=head1 DESCRIPTION
B<flood> is a program designed to perform a DoS (denial-of-service) attack
against a target computer. The target can either be a host on a local
network, a host on the Internet or any other reachable IPv4 destination.
=head2 Types of Attack
B<flood> can currently execute two different types of DoS attacks; a UDP
flood and a SYN flood.
=head3 UDP Flood
A UDP flood involves sending UDP packets of a fixed length carrying
arbitrary data. The packets are given random source addresses as well as
random source and destination ports. This attack primarily relies on the
volume of packets being transmitted to overwhelm a target. A UDP flood
can also strain a target of other resources such as memory and processor
time. When an most operating systems receive a UDP packet on a closed port,
they respond with an ICMP packet to indicate the failure. Transmitting
these ICMP packets also costs the target valueable resources.
=head3 SYN Flood
A SYN flood involves sending TCP SYN (synchronize) packets to the target.
The goal of this attack is to starve the targets possible clients by
creating dozens of 'half-open' connections.
=head1 OPTIONS
The following options are accepted:
=over 8
=item B<-d> I<seconds>
Specify the duration of the attack in seconds.
=item B<-s> I<bytes>
Overrides the default packet size.
=item B<-t> I<threads>
Set the number of threads to attack with.
=item I<address>
Target host to attack. I<address> can either be an IPv4
address or a DNS hostname. DNS names will automatically
be resolved.
=back
=head1 RETURN VALUE
Exit status is 0 if B<flood> is able to begin the attack without
any errors. If errors occur (such as the result of a bad address),
the exit status is -1.
=head1 EXAMPLES
B<flood> -d 60 example.com
Floods I<example.com> for 1 minute.
