Damon McCoy and Anmol Sheth wrote Zulu, “a light weight 802.11 wireless frame generation tool to enable fast and easy debugging and probing of 802.11 networks”. It’[s available for download here.
The tool has numerous application beyond malicious, such as testing wireless device drivers. 20+ command line options, works on Linux. Good defaults, doesn’t require you to memorize the command line syntax before you start using it.

Where might one find the Zulu tool?
