Purpose of this tool:

• The purpose of this tool is to create a packet or set of packets to send to a target, then observe the target's response with a packet capturing tool like Packet Viewer or Wireshark. You can also view the results of those packet attacks in the log files on the target. This tool can also be used to help determine where specific packet types are being lost between machines. This tool works best with wired ethernet interfaces.

Tool Capabilities

• Sends TCP, UDP, ICMP, CDP, ARP/RARP or RAW Packets to the IPv4 address specified.
• Full header control for predefined packet types. You can specify most parameters in the header such as source and destination IPv4 address, packet length, packet types, flags and checksums. The ethernet source and destination address can also be defined.
• Data Payloads can be added for certain types of packets. 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 or creating RAW packets.
• RAW Packet mode gives you full control. RAW packet mode simply means that you define the packet from ethernet header to the end using our Hex Editor or another editor. Then you send it. The length of the raw packet is limited by the interface MTU.
• 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 - if you need lots of packets, use our Packet Flooder tool. Burst rate of this tool is about 20Khz and this may vary from computer to computer.
• This is not a bandwidth testing tool - our Packet Flooder tool can pump out lots of packet through an interface and show you a bandwidth gauge and historical chart.
• This is not a traffic generator capable of stressing a network interface - again, use our Packet Flooder.
• This tool does not do handshaking of TCP connections - in other words, it does not listen for a response during a TCP handshake and send a different TCP packet in reply.
• Do not use this tool through 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.
