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.

Version 11 Packet Generator Tool Slideshow

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.
  • 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.
