the owner's permission to scan.

UDP Packet Generator Description
Craft and send UDP packets using the NetScanTools Pro Packet Generator.
Purpose of the UDP Portion of the Packet Generator Tool
- The purpose of this tool is to
give you a way to craft a UDP packet or set of UDP packets
to send to a target, then observe the target's response
with a packet capturing tool like
or view the results of those packets attacks in the
log files on the target. For example, you might alter
a UDP packet with information that is not usually found
in the packet in order to see the response of a program
or firewall to the malformed packet.
UDP Packet Generator Capabilities
- Sends UDP Packets to the IPv4
- Full header control for the UDP
packet. You can specify most parameters in the header
such as source and destination IPv4 address, source
and destination ports, packet length, packet types and
checksums. The ethernet source and destination address
can also be defined.
- Data Payload can be added.
The payload can be simple text or a file of your choosing.
The length of the data payload is limited by the interface
MTU and the packet type. We provide a Hex Editor to
assist in creating or editing binary packet payloads.
- The packet size is limited to
the MTU of your network, typically 1460 bytes for
- Scripting. Simple scripting
is provided so that you can send different types 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
- This is not a UDP traffic generator
capable of stressing a network interface.
- This tool may not operate
properly from within a 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 - be sure to
set it into 'bridged' mode.
- This tool cannot send custom packets
through WAN (PPP/SLIP) interfaces like modems or
wireless cellular modems.
