The Nestea attack is very similar to the Teardrop attack, in that it sends IP fragments to a machine connected to the Internet or a network. But, while Teardrop affects Windows based systems, Nestea is specific to the Linux operating system, and exploits a bug (commonly known as the "off by one IP header" bug) in the Linux refragmentation code (the code that reformats, or puts back together, oversize packets when they are received from a client system).
The Nestea attack is very similar to the Teardrop attack, and is run against Linux versions 2.0 and 2.1.
