RWXBO eh um programa simples nascido da ide'ia de pegar os engracadinhos
que ficam destruindo o computador de pobres mulheres indefesas.

RWXBO is a simple program that will log attemps to scan your ip range, and
logs some commands that the attacker might type.
Look at your syslog file for the logs (Usually /var/log/messages)

Tested on RedHat 5.1 Linux and SlackWare 3.5 Linux
