UDP Packet Generator Description

Craft and send UDP packets using the NetScanTools Pro Packet Generator.

About sending UDP packets using the Packet Generator

The Packet Generator tool has a UDP mode that allows you to create and send one or more UDP packets to a target. You have full control over the header flags and the other fields within the UDP header. You can add a payload either in the form of text or of a file to the packet. This tool currently sends packets with IPv4 headers. IPv6 will be coming soon.

Scripted packet transmission can be used to send multiple different UDP 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 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 Packet Viewer 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 address specified.
  • 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 ethernet.
  • 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 of devices.
  • 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.
