I have a christmas present for you: I am going to show you how to take down an entire subnet using a very sophisticated DoS attack. You must meet these prerequsites:

• Get yourself a very incompetent ISP.
• Make sure that there is absolutely no alternative to using this ISP. Alternatively: Live in a rather rural area and forget about fast Internet connections.
• Download netcat or hping. These tools are so 1337...they almost approach 1338.

Now find a comfortable chair and practice an evil laugh. Quotes such as "Yppee-ki-yay, motherf*cker" or "Army or not, you must realize you are doomed!" are always helpful.

As a last step send one UDP packet to a certain port (> 1024) to one of the machines in your ISP's net. Since your ISP is incompetent, a formidable UDP storm will arise and with less than 2kb data, you have taken an entire network down. Congratulations.

This article contains irony, but most of it is true. According to my ISP, our net has been "attacked" several times. They do not believe me that this has to be some kind of weird error (since Counter-Strike uses this port, too, our net has become quite unstable...).

Anyway: Fröhliche Weihnachten. Merry christmas. Joyeux Noël.
