Introduction

PacketGen is a pure ruby library to handle network packets.

Create network packets

PacketGen makes creating network packets in a ruby way easy. Multiple layers may be put together easily, and depending data from one layer to another is automatically updated. You even may create erroneous low-level packets to stress your network devices.

Send packets on network

Home-made packets may be easily sent over the network. Packets may be sent at levels 2 or 3 from OSI model. Erroneous packets may be sent (by example, a IP packet with bad checksum) to test network devices.

Capture packets from network

PacketGen provides an easy way to capture network packets, as Wireshark does, but these packets may be processed with ruby code, in a ruby way. Capture is always done on level 2 from OSI model.
