PacGen is an Ethernet IP TCP/UDP packet generating tool for Linux. Experimental ARP
generation removed until next release. This tool enables custom packets with configurable
Ethernet, IP, TCP, and UDP layers as well as custom payloads. As an added
feature there are configurations for packet count and a programmable time
interval between packet sends. Plaintext config files control all the functions
and represent all layers used to build packets. Included in the archive is
commented source code and a recompiled binary along with example
configs.
