If you want more info on what this does then do a search on Google for winnuke. Basically this program connects to port 139 of an unpatched Windows PC and causes it to go into the Blue Screen of Death (BSOD) and so if you get any script kiddies trying to hack you then you can try using this.
Syntax is:
./winnuke 123.123.123.123
where 123.123.123.123 is the tcp/ip address of the attacker.
Ping them after you have run winnuke and if they dont respond then you have successfully put them into BSOD-land :-)

Copy winnuke to /boot/home/config/bin so that you can use it anywhere in your BeOS Terminal session.

Source is included as is a BeOS Project file. If you compile it for PPC add it below where it says "Add Additional Location".
