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

Types of Packets Generated

These pages explore the modes of Packet Generation:

Sending a TCP Packet

Sending a UDP Packet

Sending an ICMP Packet

Sending a CDP Packet

Sending an ARP Packet

RAW packet sends are the most versatile. You specifiy the whole packet from ethernet headers to the end and send it. Any protocol that works with ethernet can be sent.
