aircrack-ng 1:0.9-1 (sparc binary) in ubuntu hardy

 aircrack-ng is an 802.11a/b/g WEP/WPA cracking program that can recover a
 40-bit, 104-bit, 256-bit or 512-bit WEP key once enough encrypted packets have
 been gathered. Also it can attack WPA1/2 networks with some advanced
 methods or simply by brute force.
 .
 It implements the standard FMS attack along with some optimizations,
 thus making the attack much faster compared to other WEP cracking tools.
 It can also fully use a multiprocessor system to its full power in order
 to speed up the cracking process.
 .
 aircrack-ng is a fork of aircrack, as that project has been stopped by
 the upstream maintainer.
