Zulu is a light weight 802.11 wireless frame generation tool to enable fast and easy debugging and probing of 802.11 networks. It has an intuitive command line interface and operates with the unmodified madwifi-ng and partially with prism based Linux network drivers. Individual fields in frames can be set or unset, generating frames that possibly violate the IEEE 802.11 protocol. It can generate all control, data, and management frame types and subtypes.

Zulu is planned to be a tool similar to hping only for wireless instead of TCP/IP.
