Warning:
NEVER send specially constructed
packets a computer you do not own or have
the owner's permission to scan. |

ARP/RARP Packet Generator Description
Craft and send ARP or RARP packets using the NetScanTools Pro Packet Generator.
About sending ARP or RARP packets using the Packet Generator
The Packet
Generator tool's ARP/RARP mode allows you to create and send one
or more ARP or RARP packets to a group of systems in an
IPv4 subnet. You have full control
over the fields within the header. This protocol
is used by ethernet connected IPv4 devices to
find the MAC address of an interface given an
IPv4 address.Scripted packet
transmission can be used to send multiple
different ARP or RARP packets.

Important Notes:
-
This tool
uses WinPcap to send packets. The interface
you use to send packets must be compatible with
WinPcap. Best results are usually obtained from a wired ethernet interface or a 802.11
wireless interface.
-
This is not
a
Packet Flooder or Traffic Generator. It cannot send packets
at a rate necessary to stress or otherwise saturate
an interface.

Purpose of the ARP/RARP Portion of the Packet Generator Tool
- The purpose of this tool is to
give you a way to craft an ARP or RARP packet or set of
ARP packets
to send to network, then observe the response
by various devices with a packet capturing tool like
Packet Viewer
or view the results of those packets attacks in the
log files on the target. ARP can be used to find
devices on a subnet even if they are hidden from
view with a firewall.
ARP/RARP Packet Generator Capabilities
- Sends ARP or RARP Packets to the
network mac address you specify. There are seven
presets: B31, B16, B8, GRP, M0, M1 and M3. There is
also a standard ARP preset (all Fs).
- Full header control for the
ARP
packet. You can specify most parameters in the
header such as hardware type, protocol type,
hardware address length, protocol length, operation,
source and destination IPv4 and MAC addresses.
- Scripting. Simple scripting
is provided so that you can send different types of
ARP packets.
Scripted packet transmission can be used to send packets
with parameters changing according to your script.
What this tool does not do:
- This is not a packet flooding
tool. Burst rate is about 20Khz and this may vary
from computer to computer.
- This is not a bandwidth testing
tool. You are looking for a piece of dedicated hardware:
Agilent Technologies and Fluke both make these type
of devices.
- This is not a traffic generator
capable of stressing a network interface.
- Do not use this tool if you have
an active virtual machine ethernet interface. This
tool works best with physical ethernet interfaces. You
are welcome to try it with your virtual machine, but
do not count on it working perfectly.
- This tool cannot send custom packets
through WAN (PPP/SLIP) interfaces like modems or
wireless cellular modems.
