In my travels, I've come across some interesting (and frankly stupid)
things.

This one takes the cake!

The following article showed up in a hackers newsgroup
and I thought I'd place it here for comment (and possible solutions
to reduce its effectivenes).

so. here goes......
**************************************************

Here is the source code to httpdkiller.c . It is one of the simplest 
and most effective apache web server attacks I have seen. It is 
written for linux but could be ported to other platforms. If you 
port it to a different os, email me the source code and I'll post 
it up here on the site. Save the following file as httpdkiller.c . 
Then compile it by typing: gcc httpdkiller.c -O2 -o httpdkiller
