• Introduction Nping is an open source tool for network packet generation, response analysis and response time measurement. Nping can generate network packets for a wide range of protocols, allowing users full control over protocol headers. While Nping can be used as a simple ping utility to detect active hosts, it can also be used as a raw packet generator for network stack stress testing, ARP poisoning, Denial of Service attacks, route tracing, etc. Nping's novel lets users see how packets change in transit between the source and destination hosts. That's a great way to understand firewall rules, detect packet corruption, and more. Nping has a very flexible and powerful command-line interface that grants users full control over generated packets.

Nping is an open source tool for network packet generation, response analysis and response time measurement. It is free and open source and runs on Linux, *BSD.

Nping's features include: • Custom TCP, UDP, ICMP and ARP packet generation. • Support for multiple target host specification. • Support for multiple target port specification.

• Unprivileged modes for non-root users. • for advanced troubleshooting and discovery. • Support for Ethernet frame generation. • Support for IPv6 (currently experimental). • Runs on Linux, Mac OS and MS Windows. • Route tracing capabilities.

• Highly customizable. • Free and open-source.

A Packet Generating and Crafting Tool The NetScanTools Pro Packet Generator tool allows you to craft or build a TCP, UDP, ICMP, CDP (Cisco® Discovery Protocol), ARP/RARP or RAW packet and send one or more packets to a target IPv4 address. You have full control over the headers: ethernet source and destination MAC addresses, IP, TCP, UDP or ICMP header fields.

You can send different types of packets in succession using scripting. You can also play back a previously saved packet capture file. Related Tool Links • • • • • •. Packet Generator 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 simply means that you define the packet from ethernet header to the end using our Hex Editor or another editor. Then you send the packet. The length of the raw packet is limited by the interface MTU. • Playback previously saved.pcap files at the rate they were captured or as fast as possible. • The packet size is limited to the MTU of your network, typically 1460 bytes for ethernet.

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. • Virtual machine ethernet interfaces. This tool works best with physical ethernet interfaces and we do use it with Oracle VirtualBox VMs. Just be sure to set the VM network interface to bridged mode so that it goes directly to your host physical ethernet interface without going through the VM NAT interface. What this tool does not do • This tool is NOT a traffic generator or packet flooding tool capable of stressing a network interface - if you need to send lots of UDP packets, use our. Burst rate of the Packet Generator tool is about 20Khz and this may vary from computer to computer.

• This is not a bandwidth testing tool. You are looking for dedicated hardware: Agilent Technologies and Fluke both make these type of devices. • This tool does not support 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. So if you send a SYN and a SYN/ACK comes back, this tool does not continue to build up the TCP connection. • This tool may or 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 does not have the ability to send custom packets through WAN (PPP/SLIP) interfaces like modems or wireless cellular modems. This tool is limited to sending through wired ethernet or wireless 802.11x interfaces.
